Abstract

Third-wave behavioural interventions are increasingly popular for treating and preventing mental health conditions. Recently, researchers have begun testing whether these interventions can effectively targeting eating disorder risk factors (disordered eating, body image concerns). This meta-analysis examined whether third-wave behavioural interventions (acceptance and commitment therapy; dialectical behaviour therapy; mindfulness-based interventions; compassion-focused therapy) show potential for being effective eating disorder prevention programs, by testing their effects on eating disorder risk factors in samples without an eating disorder. Twenty-four studies (13 randomized trials) were included. Most studies delivered selective prevention programs (i.e. participants who reported elevated risk factor). Third-wave interventions led to significant pre–post (g = 0.59; 95% CI = 0.43, 0.75) and follow-up (g = 0.83; 95% CI = 0.38, 1.28) improvements in disordered eating, and significant pre–post improvements in body image (g = 0.35; 95% CI = 0.13, 0.56). DBT-based interventions were associated with the largest effects. Third-wave interventions were also significantly more efficacious than wait-lists (g = 0.39; 95% CI = 0.09, 0.69) in reducing disordered eating, but did not differ to other interventions (g = 0.25; 95% CI = –0.06, 0.57). Preliminary evidence suggests that third-wave interventions may have a beneficial effect in ameliorating eating disorder risk.

... Pearson et al. (2012), por exemplo, encontraram que mulheres com diversos níveis de insatisfação com a imagem corporal apresentaram redução significativa da ansiedade em relação ao corpo e aumento dos processos de aceitação e flexibilidade psicológica após uma intervenção com a Terapia de Aceitação e Compromisso (em inglês, ACT), um modelo comportamental contextual que utiliza intervenções de aceitação, desfusão, ação comprometida e mindfulness para reduzir a esquiva experiencial. Indo ao encontro dos achados de Person et al. (2012), uma recente metanálise de intervenções comportamentais contextuais indicou que psicoterapias com elementos de aceitação, mindfulness e compaixão foram moderadamente eficazes para a redução da insatisfação com o corpo e aumento da flexibilidade da imagem corporal (Linardon et al., 2019). ...
... A efetividade das intervenções comportamentais na flexibilidade da imagem corporal salienta a necessidade de mais estudos focados na efetividade e na aceitabilidade de intervenções com imagem corporal, sobretudo no contexto brasileiro e com públicos alvos diversos (Griffiths et al., 2018;Guest et al., 2019;Laus et al., 2014;Linardon et al., 2019). O presente estudo objetivou (a) sistematizar e avaliar os efeitos de uma intervenção intensiva que busca promover flexibilidade da imagem corporal, flexibilidade psicológica e habilidade de atenção plena (mindfulness). ...
... Esses dados são coerentes com resultados anteriores de intervenções efetivas para a melhora da imagem corporal (Alleva et al., 2015). Mais importante para o presente estudo, a intervenção incluiu componentes de aceitação, mindfulness e autocompaixão que foram efetivos mesmo em um formato breve, o que sugere algum nível de aproximação com tratamentos de longo prazo efetivos para a melhora da imagem corporal (Linardon et al., 2019). Os resultados aqui apresentados são também similares a outras intervenções breves com populações de mulheres que apresentam insatisfação com a imagem corporal. ...

Esse estudo objetivou sistematizar e avaliar os efeitos de uma intervenção breve (Conecta) focada na promoção de flexibilidade da imagem corporal e na redução da insatisfação com a imagem corporal e dos comportamentos de risco para transtorno alimentar (TA). Buscou-se também avaliar a aceitabilidade e viabilidade da intervenção. Trata-se de um estudo pré experimental, no qual participaram 19 estudantes universitárias, com idades entre 18 e 33 anos. A intervenção breve consistiu em três encontros presenciais semanais. Os resultados revelaram um aumento significativo nos níveis de flexibilidade da imagem corporal, mindfulness, abertura à experiência e percepção atual de saúde, além de uma redução significativa na insatisfação da imagem corporal e no risco para o desenvolvimento de TA. Esses resultados sugerem que uma oficina breve pode ser útil para estudantes universitárias que apresentem dificuldades relacionadas à imagem corporal.
... For example, a recent review of the meta-analytic evidence on ACT identified 20 meta-analyses that were based on 133 studies and 12,477 participants [22]. Results showed that ACT was efficacious across a broad range of intervention targets, including depression, [23][24][25][26][27][28][29][30] anxiety, [24][25][26][28][29][30][31][32] chronic pain, [27,29,33] substance use, [34][35][36] eating disorders [37], psychosis, [38] stress, [26,30] somatic complaints, [34] physical conditions, [23] and transdiagnostic combinations of conditions [23,31,33,39] with small to medium controlled effect sizes. Three meta-analyses also identified 17 unique RCTs that found ACT to be efficacious for smoking and other drug use [34][35][36] with preliminary evidence of efficacy for treatment of co-occurring substance use and affective disorders [18,[41][42][43][44][45]. ...
... While none of these studies were randomized trials, all provided preliminary evidence to suggest that ACT is a promising intervention for alcohol use and comorbid stress, anxiety, and/or trauma. Thekiso et al. (2015) conducted a pilot study of a group-based ACT intervention designed to enhance treatment as usual (TAU) for inpatients with AUD and either depression or bipolar disorder [37]. The ACT group received 4 weeks of daily (5 sessions/week) group ACT-based therapy, while TAU received 4 weeks of standard integrated inpatient treatment [37]. ...

Alcohol use among people living with HIV (PWH) has been increasingly recognized as an important component of HIV care. Transdiagnostic treatments, such as Acceptance and Commitment Therapy (ACT), that target core processes common to multiple mental health and substance-related problems, may be ideal in HIV treatment settings where psychological and behavioral health comorbidities are high. In advance of a randomized clinical trial (RCT), the overall objective of this study was to systematically adapt an ACT-based intervention originally developed for smoking cessation, into an ACT intervention for PWH who drink at hazardous levels. Consistent with the ADAPT-ITT model, the adaptation progressed systematically in several phases, which included structured team meetings, three focus group discussions with PWH (N = 13), and in-depth interviews with HIV providers (N = 10), and development of standardized operating procedures for interventionist training, supervision, and eventual RCT implementation. The procedures described here offer a template for transparent reporting on early phase behavioral RCTs.
... Further, CBT is designed to help individuals modify negative thought patterns, such as ruminative negative thoughts [15,20]. ACT-, DBT-, or CBT-informed programs that primarily target body image, eating disorder prevention, or self-compassion have been found to improve body dissatisfaction or self-compassion [19,[21][22][23][24][25]. Studies of generalized programs (i.e., not specifically targeted for body image or self-compassion, but with some psychological component) have shown improvements in psychological well-being as well as body image [26,27]. ...
... This provided the unique opportunity to examine changes in body positivity and self-compassion in a setting that reflects real-world use of the program as much as possible (i.e., with individuals who self-voluntarily joined the program and minimal participation requirements). For this study's primary aim, based on past work on ACT, DBT, and CBT [19,[21][22][23][24][25], we hypothesized that body acceptance, body image flexibility, and self-compassion would significantly increase from baseline to end of the program and body-focused rumination (i.e., continuous negative thought patterns) would significantly decrease. We also hypothesized that these improvements would be independent of weight lost, with no significant associations between weight loss and body appreciation, body image flexibility, self-compassion, and body-focused rumination. ...
... Our results add to this literature by showing that body positivity and self-compassion significantly improved over time. Our findings are also consistent with studies showing improvements in body image from targeted CBT-, ACT-, or DBT-based programs, as well as programs specifically targeting self-compassion [21][22][23]47,48]. Our results also contribute new knowledge by showing that changes in body positivity and self-compassion can occur in individuals who voluntarily joined and used a digital publicly available program. ...

According to recent research, body positivity and self-compassion are key outcomes that are tied to better psychological and physical health. To date, it is unclear whether body positivity and self-compassion improve, stay constant, or deteriorate over the course of a weight management program, particularly one that addresses the psychological roots of behavior change. Additionally, beyond controlled settings, there are no studies on body positivity and self-compassion in individuals who choose to join a commercial weight management program. Therefore, this single-arm prospective study examined changes in body positivity and self-compassion from baseline to the 16 week milestone of Noom Weight, a commercial behavior change weight management program informed by acceptance and commitment therapy (ACT), dialectical behavior therapy (DBT), and cognitive behavioral therapy (CBT). We also examined how baseline and over-time changes in body positivity and self-compassion predicted engagement in program-measured relevant behaviors (e.g., exercises logged). Participants were a random subset of individuals who had recently self-enrolled in the program (n = 133). Body positivity and self-compassion were measured via survey at baseline and end of the core program (16 weeks). Self-reported weight and program-recorded engagement were extracted from the program database. Compared to baseline, body appreciation, body image flexibility, self-compassion, and body-focused rumination significantly improved at 16 weeks (all ps < 0.007). Participants lost a statistically significant amount of weight (3.9 kg; t(128)) = 10.64, p < 0.001) by 16 weeks, which was 4.4% body weight. Greater engagement, especially messaging a coach, reading articles, and logging meals, was associated with improvements over time in body appreciation (r = 0.17, p = 0.04), body image flexibility (r = −0.23, p = 0.007), and the brooding component of rumination (r = −0.23, p = 0.007). Greater engagement was also associated with baseline total self-compassion (r = 0.19, p = 0.03) and self-judgment (r = 0.24, p = 0.006). The results suggest that individuals experience improvements in body positivity and self-compassion while learning about ACT, DBT, and CBT through curriculum and coaching in this setting. The results also have important clinical implications, such as the possibility that psychologically-oriented (i.e., ACT, DBT, and CBT-based) weight management could be important to improve body positivity or that baseline self-compassion could be used to target individuals at risk for lower engagement. Future work should investigate these possibilities as well as delineate the causal relationships between body positivity, self-compassion, engagement, and weight loss.
... These disorders are frequently associated with alteration in the way of seeing and living the body: with the term dysmorphophobia the DSM-5 refers to the more or less conscious concern for one or more defects or imperfections perceived in the physical appearance that are not observable, or only slightly, by others. The individual, in response to this concern that causes clinically signi icant discomfort, can carry out repetitive behaviors or mental actions that give rise to an obsessive search for change in body shapes [16,19]. ...
... An early detection of alterations in eating behavior is important in order to prevent the development of ED such as Anorexia and Bulimia Nervosa [7,19,41]. In fact, early diagnosis is associated with early intervention, not only from a psychological but also medical point of view [42,43]. ...
... Indeed, high levels of physical activity in athletes with ED can cause numerous health problems: chronic fatigue, weakened immune system, longer healing times, anemia, electrolyte imbalance, endocrine abnormalities, amenorrhea and reduced bone density [36,37]. Therefore, the scienti ic literature emphasizes the need to prevent these problems by acting on the promotion, education and information aimed at young athletes and their instructors [7,19,23,29,[44][45][46]. ...

Objective: This preliminary study focused on the description of some dysfunctional perceptions of the body image and eating habits in a sample of young. Methods: The results obtained by 55 amateur and professional volleyball players belonging to volleyball sports clubs located in the province of Reggio Emilia were examined. The age of the sample is in a range between 11 and 44 years. The participants completed the Pisa Survey for Eating Disorders (PSED), a questionnaire aimed at examining eating behavior and the perception of one’s body image. The athletes’ height and body weight were subsequently detected through direct measurement. Conclusion: The data collected through the self-evaluation questionnaire and the measurements carried out by the study made it possible to analyze the perception of the body image and the eating habits of the volleyball players belonging to the sample and to compare them with the data in the literature. The data, albeit preliminary, allow us to confirm the existence of the discrepancy between the real body image and the desired one, in a group of young athletes, who favors the adoption of non-adaptive coping strategies to control one’s own weight and body shapes typical of the vicious circle - strict diet, bingeing episodes, compensatory behaviors - which characterizes eating disorders (ED). It is therefore considered essential that body image assessment is a practice implemented in the assessment routine of these athletes, especially in consideration of the fact that body image disturbance is a very common feature in this category and is one of the main risk factors of EDs.
... In treating AN, it is recommended that the client receives a combination of psychotherapy, nutritional rehabilitation, and medical monitoring (American Psychiatric Association, 2006;Linardon et al., 2019). For youth requiring more intensive medical services, the primary and initial focus will be on rehabilitation of the body (American Psychiatric Association, 2006). ...
... Third-wave behavioral interventions such as Dialectical Behavior Therapy (DBT) and Acceptance and Commitment Therapy (ACT) have yet to show the same effcacy as CBT for eating disorders. However, there is promise of their use in prevention programs (Linardon et al., 2019). Motivational interviewing can be a key part of therapy as well, as motivation is a key predictor of change for individuals with EDs (Wade et al., 2009). ...
... Though EDs, disordered eating, and body image dissatisfaction may represent different latent constructs, they often present together, including in transgender individuals (Galupo et al., 2021;Romito et al., 2021). Importantly, rates of disordered eating are rising, and disordered eating and body image dissatisfaction are early indicators for EDs (Linardon et al., 2019;Mitchison et al., 2012). For cisgender women, a consistent risk factor and a defining feature of many EDs is body image dissatisfaction and overvaluation of weight and shape (Striegel-Moore & Bulik, 2007;Striegel-Moore & Cachelin, 2001). ...
... Conceptually, this may parallel EDs broadly. For instance, in treating EDs, health care providers may address weight and body image without focusing on the cognitive symptoms necessary for full recovery (Fairburn et al., 2003;Keski-Rahkonen et al., 2009;Linardon et al., 2019). If providers unduly attend to physical criteria, they may fail their clients by not addressing the emotional avoidance and cognitive processes underlying and maintaining EDs. ...

Conceptualizations of eating disorders (ED) have primarily been based on the experiences of cisgender women. Yet trans and nonbinary individuals (TNB) may be at greater risk than cisgender individuals to suffer from eating disorders, disordered eating, and body image concerns. The current study takes a phenomenological approach to explore how TNB individuals conceptualize eating and/or body image issues. Qualitative data were obtained from 82 TNB participants who self-reported eating and/or body image concerns. Primary analyses focused on participants’ responses to an open-ended prompt regarding how participants understand the relationships among gender identity, gender expression, and weight and shape control behaviors. Thematic analysis identified five themes: (a) gender dysphoria, (b) puberty, (c) emotion (dys)regulation, (d) gender expression, and (e) recovery/transition. Results indicate various factors salient to gender identity and expression and eating concerns. Findings extend beyond the traditional focus on gender dysphoria by highlighting other important factors for TNB individuals, such as the function ED psychopathology serves (e.g., gender avoidance and self-punishment). This broadens the ED field’s understanding of how gender dysphoria relates to ED psychopathology, rather than focusing solely on the physical body. Distress and associated behaviors related to both gender dysphoria and eating disorder psychopathology may be reciprocal and reinforcing and, as such, should be considered in tandem in treating TNB clients experiencing EDs and body image concerns. This work may better identify ED risk and maintenance within this population and thus optimize prevention and intervention.
... Recent systematic reviews and meta-analyses have primarily focused on the effects of mindfulness-and acceptance-based treatments on weight-related outcomes, with a secondary focus on eating behaviours (Lawlor et al., 2020;Rogers, Ferrari, Mosely, Lang, & Brennan, 2017). Most have used combined measures of disordered eating behaviours and attitudes and/or combined measures of restricted and dysregulated forms of eating as well as body image concerns (Lawlor et al., 2020;Linardon, Gleeson, Yap, Murphy, & Brennan, 2019;Rogers et al., 2017). To date, systematic reviews and meta-analyses on ACT-based treatments for eating behaviour change have shown moderate-to-large effects on measures that combine restrained and dysregulated forms of eating (Godfrey, Gallo, & Afari, 2015;Lawlor et al., 2020;Linardon et al., 2019). ...

Background An increasing number of studies have investigated the efficacy of Acceptance and Commitment Therapy (ACT) for the reduction of dysregulated eating behaviours such as binge eating and emotional eating. However, little is known about their short- and long-term efficacy and underlying mechanisms of change. Objectives To conduct a systematic effect size analysis to estimate the efficacy of ACT-based treatments on measures of dysregulated eating and of psychological flexibility, a theorized ACT mechanism of change. Methods Literature searches were conducted in PsycInfo, Medline, Web of Science, and ProQuest Dissertations. Within-group and between-group standardized mean differences were computed using Comprehensive Meta-Analysis Version 3. Additional subgroup and meta-regression analyses by study characteristics were conducted. Results A total of 20 publications (22 samples, n = 1269) were included. Pre-post and pre-follow-up effects suggest that ACT-based treatments are moderately effective in reducing dysregulated eating behaviours and increasing psychological flexibility. These effects were comparable for binge-eating and emotional eating outcomes and for face-to-face interventions, Web-based interventions, and interventions that used a self-help book. Longer treatments were associated with larger outcome effect sizes, and changes in psychological flexibility were not associated with changes in dysregulated eating outcomes. Small significant effects were found in favour of ACT when compared to inactive control groups. The only three studies that included active control groups and did not show significant differences in outcomes between ACT and other treatments. Conclusion Future studies should aim to compare ACT-based treatments to active treatments and to provide empirical evidence for the theoretical mediating role of psychological flexibility in reported changes in eating behaviour.
... The preliminary conversational content and decision tree for KIT was developed by the authors, in collaboration with the helpline and communications teams at the Butterfly Foundation (a national charity based in Australia, which provides support for body image and eating disorders). The conversation content was based on evidence-based information/interventions for eating disorders, specifically, psychoeducation, cognitive behavioral therapy (CBT), acceptance commitment therapy (ACT), and mindfulness [25,26], and adapted for delivery by a chatbot. Owing to the short and simple style of conversations KIT was designed to deliver, we were highly selective in the therapeutic elements we chose from CBT (eg, education on cognitive distortions or unhelpful thinking styles), ACT (eg, practicing detaching from unhelpful thoughts via cognitive defusion exercises), and mindfulness (eg, mindful breathing) [17,25,26]. ...

Background Body image and eating disorders represent a significant public health concern; however, many affected individuals never access appropriate treatment. Conversational agents or chatbots reflect a unique opportunity to target those affected online by providing psychoeducation and coping skills, thus filling the gap in service provision. Objective A world-first body image chatbot called “KIT” was designed. The aim of this study was to assess preliminary acceptability and feasibility via the collection of qualitative feedback from young people and parents/carers regarding the content, structure, and design of the chatbot, in accordance with an agile methodology strategy. The chatbot was developed in collaboration with Australia’s national eating disorder support organization, the Butterfly Foundation. Methods A conversation decision tree was designed that offered psychoeducational information on body image and eating disorders, as well as evidence-based coping strategies. A version of KIT was built as a research prototype to deliver these conversations. Six focus groups were conducted using online semistructured interviews to seek feedback on the KIT prototype. This included four groups of people seeking help for themselves (n=17; age 13-18 years) and two groups of parents/carers (n=8; age 46-57 years). Participants provided feedback on the cartoon chatbot character design, as well as the content, structure, and design of the chatbot webchat. Results Thematic analyses identified the following three main themes from the six focus groups: (1) chatbot character and design, (2) content presentation, and (3) flow. Overall, the participants provided positive feedback regarding KIT, with both young people and parents/carers generally providing similar reflections. The participants approved of KIT’s character and engagement. Specific suggestions were made regarding the brevity and tone to increase KIT’s interactivity. Conclusions Focus groups provided overall positive qualitative feedback regarding the content, structure, and design of the body image chatbot. Incorporating the feedback of lived experience from both individuals and parents/carers allowed the refinement of KIT in the development phase as per an iterative agile methodology. Further research is required to evaluate KIT’s efficacy.
... While clarification of emotional experience may be a crucial first step, this might be followed by attempts to increase accessibility of existing adaptive regulation strategies and develop new ones, including emotion acceptance, in response to distress. Dialectical Behaviour Therapy (DBT) for BED and BN was developed in response to patients who do not always benefit from Cognitive Behaviour Therapy (CBT)-focused treatments [62], but this and other third-wave interventions such as acceptance and commitment therapy (ACT), compassion-focused therapy (CFT) and mindfulness have wider potential in the treatment of people with EDs [63]. Their relevance in this context comes from the fact that in contrast to pure CBT which attempts to prevent strong negative emotions being activated, third wave interventions are response-focused [64]: centred around accepting, managing and finding adaptive ways to moderate the experience of strong emotions when they arise. ...

Whether third wave, response-focus therapies might be useful at a time when people have limited control over the antecedents of negative emotion is an intriguing query for future researchers. ...

Objective The Covid-19 pandemic has wrought disruption to everyday life and services, and emerging evidence suggests that those with eating disorders (EDs) are likely to experience marked distress and exacerbation of their symptoms. However, little is known around the most relevant factors to symptom change; whether certain emotion regulation and coping strategies are linked to better outcomes; and how people with EDs are adjusting to psychological interventions moving online. Method In a mixed-method design, we collected qualitative and quantitative data from 207 (76 males) self-selected UK residents with self-reported ED, who described and ranked impacts of the pandemic on their symptoms. Regression analysis examined whether emotion regulation strategies were associated with self-reported symptom change, ED symptomatology, and negative emotional states. Thematic analysis explored participants’ experiences of the pandemic, particularly factors affecting their ED, coping strategies used, and experiences of psychological intervention. Results Most participants (83.1%) reported worsening of ED symptomatology, though factors affecting symptom change differed between specific EDs. Emotion regulation, such as having fewer strategies, poorer emotional clarity, and non-acceptance of emotions, explained nearly half of the variance in emotional distress during the pandemic. Qualitative findings indicated that difficult emotions (such as fear and uncertainty), changes to routine, and unhelpful social messages were triggering for participants during the pandemic. While some participants described employing positive coping strategies (such as limiting social media exposure), many reported using ED behaviours (among other maladaptive strategies, like alcohol use) to cope with the pandemic. Finally, loss of treatment support, feeling underserving of support and experiencing a ‘detached connection’ online were further exacerbating factors for these participants. Discussion While our sample was self-selected and may not represent all people with EDs, our results suggest that people with EDs have been strongly affected by the pandemic. Some aspects of online treatment were found to be beneficial but our findings suggest it also needs some improvement. Our paper discusses implications for online treatment such as taking into account personal circumstances and, in a time where people have limited control over the antecedents of negative emotion, the need to develop skills to manage emotions when they arise.

... Step 3: Formal intervention-patients also scoring poorly on psychometric measures could be referred for assessment by a trained mental health clinician either within the Hospital Trust or via their local NHS Talking Therapies for Anxiety and Depression Service (formerly known as IAPT). Here, specialist psychological interventions such as cognitive behavioural therapy and compassion focused therapy, which have been shown to be effective in the treatment of body image disturbance can be provided [33]. ...

Background Abdominal wall hernias (AWH) are frequently large and deforming. Despite this, little is known about how AWH impact upon body image. This study is the first study to qualitatively examine patients’ subjective lived experiences of how AWH affects their body image. Methods Fifteen patients were interviewed from a purposive sample of AWH patients awaiting surgery until no new narrative themes emerged. Interviews explored patient thoughts and experiences of AWH and body image. Data were examined using interpretative phenomenological analysis (IPA). Results Two key themes pertaining to body image were identified: “Changes to perceptions of self” and “Fears concerning other’s perceptions of them”. Both themes were often interrelated and displayed detrimental effects AWH had on patients’ body image. Conclusions Our findings illustrate that AWH detrimentally affected patients’ body image. This aspect of patient care can be treated and managed through better pre-operative information, including on body image as part of a holistic needs assessment (HNA), and ensuring the results are addressed in a patient care package. These development suggestions may positively affect the AWH patient’s experience and outcomes in terms of Quality of Life (QoL) by preparing patients better for realistic results regarding what can be achieved in terms of form, function thus making a more holistic recovery from surgery.
... However, comparing the two interventions did not result in significant differences over the follow-up years, suggesting that a new program such as DBT may be as effective as a well-established program such as TAU-CBT [29]. A recent meta-analysis, reported that DBT was found to produce the largest effects in reducing disordered eating behaviors among other third-wave interventions [30]. ...

Purpose Individuals with eating disorders (ED) and comorbid borderline personality disorder (BPD) may benefit from therapies focusing on emotion regulation, such as dialectical behavioral therapy (DBT). The aim of the study was to evaluate the effectiveness of one-year standard DΒΤ enhanced with cognitive-behavioral therapy (CBT) strategies for patients suffering from ED and BPD. Methods Seventy-two BPD and ED (anorexia and bulimia nervosa) participants were recruited from the eating disorders unit of the 1st Psychiatric Department of National and Kapodistrian University of Athens. All participants completed one year of standard DBT. ED-related behaviors were added to the treatment plan according to the DBT targeting hierarchy. Individual therapy and skills training group sessions were adapted to incorporate CBT strategies for nutritional and weight restoration. BPD and ED symptomatology were measured at the beginning and at the end of one year of treatment. Results The major finding of the study was the significant improvement of patients in all the outcome measurements after one year of treatment. The study's second finding was that the severity of BPD symptomatology was significantly related to the severity of ED symptomatology. It was also shown that improvement of the patients coping skills was correlated with the reduction of ED and BPD symptomatology. Conclusions These results support previous studies on the effectiveness of DBT for comorbid BPD and EDs. Despite the promising results, randomized controlled trials are needed to establish the efficacy of DBT for BPD and ED patients. Level of evidence Level IV: Evidence obtained from multiple time series with or without the intervention, such as case studies. Dramatic results in uncontrolled trials might also be regarded as this type of evidence.
... While usually considered as part of the CBT application, these interventions apply newer principles and techniques to target and improve the function or awareness of cognitive and emotional processes (Hayes, 2004). A meta-analysis of 24 studies (most studies were selective prevention programs) concluded that there is preliminary evidence supporting the benefits of third-wave behavioral interventions in reducing the risk of EDs (Linardon et al., 2019). Significant pre-post improvements were observed in disordered eating (g ¼ 0.59, 95% CI: 0.43-0.75) ...
... We know that these factors are essential for the appearance of the core symptoms of eating disorders, and among the most important, the following should be noted as determinants: the existence of some type of abuse during childhood, family presence of eating disorders or obesity, family presence of personality, mood or other mental disorders, rigid nutritional habits, body dysmorphia or dissatisfaction with selfimage, the presence of excessive physical activity routines, low self-esteem. A systematic review by showed that the identification of these elements is essential for a correct multidisciplinary intervention [230]. ...

Anorexia nervosa is a psychiatric disorder with an unknown etiology that is characterized by an individual’s preoccupation with their weight and body structure while denying the severity of their low body weight. Due to the fact that anorexia nervosa is multifaceted and may indicate the coexistence of genetic, social, hormonal, and psychiatric disorders, a description of non-pharmacological interventions can be used to ameliorate or reduce the symptoms of this condition. Consequently, the purpose of the present narrative review is to describe the profile’s context in the anorexic person as well as the support they would require from their family and environment. In addition, it is aimed at examining preventative and non-pharmacological interventions, such as nutritional interventions, physical activity interventions, psychological interventions, psychosocial interventions, and physical therapy interventions. To reach the narrative review aims, a critical review was conducted utilizing both primary sources, such as scientific publications, and secondary sources, such as bibliographic indexes, web pages, and databases. Nutritional interventions include nutritional education and an individualized treatment for each patient, physical activity interventions include allowing patients to perform controlled physical activity, psychological interventions include family therapy and evaluation of the existence of other psychological disorders, psychosocial interventions include management of the relationship between the patient and social media and physical therapy interventions include relaxation massages and exercises to relieve pain. All these non-pharmacological interventions need to be individualized based on each patient’s needs.

Disordered eating is a serious health concern globally. The etiology is complex and multidimensional and differs somewhat for each specific eating disorder. Several risk factors have been identified which include psychological, genetic, biochemical, environmental, and sociocultural factors. Poor body image, low self-esteem, teasing, family dynamics, and exposure to media images have also been identified as risk factors. While it is enticing to consider a single behavioral risk factor, doing so fails to consider the documented environmental, social, psychological, biological, and cultural factors that contribute to the development of an eating disorder in a multidimensional and complex integration that is undoubtedly unique to everyone. Focusing only on any one factor without taking the complex etiology into account is remiss. For example, it has been suggested that the use of dietary supplements may lead to eating disorders, despite a lack of evidence to support this conjecture. Therefore, the purpose of this review is to examine the evidence-based risk factors for eating disorders and discuss why connecting dietary supplements to eating disorder etiology is not supported by the scientific literature and may interfere with treatment. Established, effective prevention and treatment approaches for eating disorders should be the focus of public health initiatives in this domain.

... Weight is the force that is "experienced" by an object due to gravity. Hence, body image may be considered both "relative" and "subjective," as it may also be dynamic and seen as "amenable to change" [112]. However, human body image seems to be a more complex concept than only a mental picture of dimensions, but rather a multifaceted construct made of neurological, psychological, and sociocultural elements [113]. ...

Eating disorder, “a persistent disturbance in eating and its related behaviors” affects both “food consumption and its absorption”, and the overall physical and mental wellbeing of affected individuals. ED is reported worldwide, across gender, ethnical, racial, and socioeconomic strata. Societal emphasis on gender based body-ideals puts extra pressure on adolescents to achieve or maintain unattainable weigh or body shapes, at the cost of them becoming unwell. ED has a complex etiology where an interplay between genetics and environment brings about the onset of symptoms as early as prepubertal years. With their fluctuating and chronic nature, ED may affect perception, emotions, cognition, and behavior. The interface between ED, overeating and obesity, as well as the recent surge in reported cases of ED during Corona pandemic, has focused much attention on eating pathology amongst adolescents. Many adolescents (particularly boys) specially in a prodromal phases of ED, do not yet meet diagnostic thresholds for ED and hence do not receive timely or appropriate professional help. In the current chapter, we aim to 1- address the issues surrounding early recognition of ED symptoms in adolescents under a general umbrella term, “Disordered Eating”, and 2- highlight the importance of societal influence on vulnerable individuals.
... According to the prominent transdiagnostic CBT theory on which most CBTs including both CBT-E and MABTs are based, OSW contributes to restrictive eating and other weight-control behaviors (e.g., purging, compulsive exercise) that maintain BN symptoms. Reductions in weight/shape concerns on the Eating Disorder Examination (EDE; Cooper & Fairburn, 1987) have been associated with improvements in BN symptoms at post-treatment and follow-up (Dahlenburg et al., 2019;Linardon et al., 2019), suggesting that reductions in OSW may be a key mechanism underlying improvements in BN (Linardon et al., 2016;Vall & Wade, 2015). ...

Overvaluation of shape and weight (OSW) is supported as an important mechanism underlying improvement in bulimia nervosa (BN) during behavioral therapies (CBTs). It is not yet clear, however, whether changes in OSW temporally precede and prospectively predict changes in BN symptoms during CBTs, limiting the ability to establish causality. The present study is the first to examine whether session-by-session changes in OSW prospectively predict session-by-session changes in BN symptoms during CBTs and clinical outcomes at the end-of-treatment. Participants with BN (n = 44) who received 20 sessions of CBTs completed a brief survey at each session assessing OSW and BN symptom frequency during the past week. Results showed small but significant session-by-session reductions in OSW and BN symptoms during CBTs. Session-by-session improvements in OSW in any given week prospectively predicted reductions in restrictive eating, binge eating, and compulsive exercise in the following week but did not prospectively predict improvements in purging, while improvements in restrictive eating and compulsive exercise in any given week prospectively predicted reductions in OSW in the following week. Average session-by-session change in OSW during treatment was positively associated with remission status and improvements in eating pathology at the end-of-treatment. Changes in OSW temporally precede and prospectively predict changes in BN symptoms during CBTs, and vice versa. These findings may have critical implications for treatment planning and implementation.
... Thirdly, given the connection between anorexia and bullying, it is crucial to integrate blocks devoted to the principles of maintaining a healthy lifestyle, care for the body and a set of recommendations on how to critically evaluate messages about body-and beauty-related topics into prophylactic programs aiming to affect bullying victimization for students, parents, and school staff. As with bullying awareness programs the details on these programs could be found by school psychologists in metaanalytical reviews, to exemplify (Beccia et al., 2018;Leme et al., 2018;Linardon et al., 2019). ...

Eating disorders significantly impact the quality of life of the persons they affect, as well as their involvement in school bullying. People with bulimia and binge-eating disorders are known to be more likely to be victims of bullying; however, studies provide mixed evidence on the connection between bullying and anorexia. Therefore, in this paper, we suggest an explanation for the bullying victimization of people with anorexia. Our theoretical framework is based on psychoanalytical research on eating disorders, and we illustrate our arguments with the results of biographical interviews with 50 girls who have been diagnosed with anorexia. We show that a hostile family environment may influence the girls’ proneness to fall victim to school bullying. Therefore, school staff hoping to address the involvement of girls with anorexia in bullying should be aware of the role that family members play in bullying victimization and tailor interventions accordingly.

Eating disorders (ED) constitute a serious public health issue affecting predominantly women and appearing typically in adolescence or early adulthood. EDs are extremely difficult to treat, as these disorders are ego-syntonic, and many patients do not seek treatment. It is vital to focus on the development of successful early-intervention programs for individuals presenting at risk and are on a trajectory towards developing EDs. This study is a randomized controlled trial evaluating an innovative digital gamified Acceptance and Commitment early-intervention program (AcceptME) for young females showing signs and symptoms of an ED and at high risk for an ED. Participants (n = 92; Mage = 15.30 years, SD = 2.15) received either AcceptME (n = 62) or a waitlist control (n = 30). Analyses indicated that the AcceptME program effectively reduced weight and shape concerns with large effects when compared to waitlist controls. Most participants scored below the at-risk cut-off (WCS score < 52) in the AcceptME at end-of-intervention (57.1%) compared to controls (7.1%), with odds of falling into the at-risk group being 14.5 times higher for participants in the control group. At follow-up, 72% of completers reported scores below the at-risk cut-off in the AcceptME group. The intervention also resulted in a decrease in ED symptomatology and increased body image flexibility. Overall, results suggest that the AcceptME program holds promise for early-intervention of young women at risk for developing an ED.
... Overall, clinical research referred to the generic term of body image disturbance as a cognitive-affective attitude toward one's own body that embraces various concepts related to negative body image, such as body dissatisfaction, avoidance, or, on the contrary, compulsive control of one's own body, detachment, and estrangement feelings towards it and worries about particular body parts, shapes or functions [44]. All these psychopathological dimensions seem to pertain to a core feature preceding the onset of behavioural symptoms [45], often persisting after treatments [46], and being associated with a worse prognosis [2,47] and with a higher likelihood of relapse after remission [48]. ...

Cognitive, psychodynamic, and phenomenological scholars converged their attention on abnormal bodily phenomena as the core psychopathological feature of eating disorders (EDs). While cognitive approaches focus their attention on a need for “objective” (i.e., observable, measurable) variables (including behaviours and distorted cognitions), the phenomenological exploration typically targets descriptions of persons’ lived experience. According to a new emerging phenomenological perspective, the classic behavioural and cognitive symptoms of EDs should be considered as epiphenomena of a deeper core represented by a disorder of the embodiment. The cognitive–behavioural model is the most studied and, up till now, clinically efficacious treatment for EDs. However, as any coherent and scientifically grounded model, it presents some limitations in its application. Numerous patients report a chronic course, do not respond to treatment and develop a personality structure based on pathological eating behaviours, since “being anorexic” becomes a new identity for the person. Furthermore, the etiopathogenetic trajectory of EDs influences the treatment response: for example, patients reporting childhood abuse or maltreatment respond differently to cognitive-behavioural therapy. To obtain a deeper comprehension of these disorders, it seems important to shift attention from abnormal eating behaviours to more complex and subtle psycho(patho)logical features, especially experiential ones. This characterisation represents the unavoidable premise for the identification of new therapeutic targets and consequently for an improvement of the outcome of these severe disorders. Thus, the present review aims to provide an integrated view of cognitive, psychodynamic, and phenomenological perspectives on EDs, suggesting new therapeutic targets and intervention strategies based on this integrated model. Level of Evidence: Level V. Level of evidence Level V: Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

... While theoretically, this process is in line with those posited by ACT interventions, longitudinal replication of our analyses and research specifically examining cognitive defusion as a process mechanism in interventions for EDs is needed to support this notion. To date, there is a small but growing body of evidence suggesting that ACT is effective in decreasing ED symptom severity and body image concerns [6,50], and that among a sample of overweight/obese adults, led to significant improvements in the eating for physical rather than emotional reasons component of IE from pre-to post-intervention. However, to our knowledge, no studies have explicitly examined the use of ACT-based interventions targeting body image-related fusion within individuals with eating disorders, or examined this as a possible therapeutic mechanism of change that may promote adaptive eating behaviors, such as IE within these populations. ...

Purpose This study sought to explore the associations between Intuitive Eating (IE), eating disorder (ED) symptom severity, and body image-related cognitive fusion within a clinical sample. IE was also examined as a possible mediator in the relationship between body image-related fusion and ED symptoms. Methods This study includes cross-sectional analyses with data from 100 adult females and 75 adolescent females seeking residential treatment for an ED. Self-reported demographic information, ED symptoms, IE behaviors, and body image-related cognitive fusion were collected from participants within the first week of treatment following admission to the same residential ED treatment facility. Results ED symptom severity was significantly negatively associated with three of the four domains of IE; unconditional permission to eat, reliance on hunger and satiety cues, and body-food choice congruence. A significant mediational effect of IE on the relationship between body image-related fusion and ED symptoms through IE behaviors was observed (β = 11.3, SE = 0.003, p < 0.001). This effect was only observed for the unconditional permission to eat (β = 0.13, p = 0.003) and reliance on hunger and satiety cues (β = 0.10, p = 0.005) domains of IE when the domains were subsequently analyzed individually. Conclusion Unconditional permission to eat and reliance on hunger and satiety cues appear to be particularly influential domains of IE in the relationship between body image-related fusion and ED symptom severity. It is possible that changes in these IE domains may be mechanisms through which body image-related fusion influences ED symptoms. Future longitudinal research is needed to better understand the relationship between body image-related cognitive fusion and IE and the potential for targeting these constructs specifically in the context of ED treatment.

Eating disorders (ED) are defined as specific and severe alterations in food intake, observed in people who present distorted patterns in the act of eating and are characterized by either overeating or stopping do it. Contextual or third generation therapies are being used to treat eating disorders, their objective is to modify the way in which people relate to their thoughts about weight, their physical appearance and eating, to favor the processes of acceptance and cognitive flexibility. The objective of this study is to review the current panorama of contextual or third generation therapies as therapeutic intervention in eating disorders, selecting for their development of adaptations and specific processes in eating disorders, Dialectical Behavioral Therapy (DBT) and Dialectical Behavioral Therapy (DBT), Acceptance and Commitment (ACT) and also including in the review, the Mindfulness-based Conscious Eating Program (MB EAT). We consider that DBT has shown greater affective stabilization, improvement in levels of depression and anxiety, reduction of binge eating and greater adherence to treatment. ACT has been shown to be effective in binge-eating behavior and body dissatisfaction caused by cognitive inflexibility. MB EAT has achieved utility by creating greater acceptance and flexibility in the act of eating, recognizing signs of hunger and satiety, in addition to demonstrating reduction of compulsive eating and mindfulness in eating. More studies are necessary, especially with ACT and MB-EAT, to achieve a higher level of evidence.

Positive body image is a contemporary construct, having only received research attention within the past two decades in an effort to elicit a more holistic, comprehensive account of the concept of body image. Nevertheless, emerging literature has suggested its direct and indirect association with improved outcomes, including indicators of well-being (e.g. self-compassion) and feelings towards the self (e.g. self-esteem). Positive body image has therefore been suggested as both a potential technique and a target of actionable therapeutic work for cultivating both physical and psychological well-being. First, through insights from quantitative and qualitative seminal works, this paper demonstrates that positive body image is: (i) a multidimensional construct, distinct from negative body image; (ii) a confluence of theoretical disciplines and influences; (iii) protective, with therapeutic capacities; (iv) a positive outcome; (v) young, yet flourishing; and (vi) socially and politically relevant. Thus, complementing what positive body image is, this paper further situates therapeutic practice within the field of positive body image by delineating and contextualising their reciprocal capacities and relevant techniques.

PurposeFor patients with eating disorders (EDs), early engagement in care is usually considered as a positive prognostic factor. The aim of the present study is to investigate how a single-day intervention devoted to an early experiential exposure to a variety of psychotherapy approaches, supports transition to specialised care and commitment to change in patients with EDs.Methods One hundred and sixty-nine outpatients newly diagnosed with an ED took part in a single-day workshop for groups of up to 10 patients, where they discovered and experienced eight psychotherapeutic approaches. Motivation to change care, and level of insight were assessed at baseline and 10 days after the intervention.ResultsMotivation and commitment to take active steps toward change (expressed by the “Committed Action” composite score) significantly improved after intervention (p<0.001), and a significant number of patients specifically moved from “contemplation” to “action” stage (p<0.001). The improvement of motivation to change is significantly associated to an increase of insight capacity (p<0.001), and this for almost all dimensions.ConclusionA single-day session devoted to experiencing a range of group psychotherapies increased patients’ insight and motivation to actively engage in care. Further studies including different factors and long-term outcomes evaluation may be necessary to better establish which aspects are specifically involved in patients' increased motivation for care and confirm potential longer-term benefits of this intervention.Level of evidenceLevel V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Objective: Self-compassion - the tendency or ability to treat oneself kindly in times of failure or distress - may be a natural fit to support individuals who struggle with weight management. However, while self-compassion shows promise with improving health behaviours, the associations self-compassion has on weight management outcomes are unclear. The objective of this systematic review was three-fold: (1) to evaluate whether self-compassion interventions can increase individual self-compassion in the context of weight management, (2) to investigate if self-compassion interventions can improve weight management outcomes, defined as healthier eating, increased physical activity, or reduced weight and finally, (3) to explore whether these benefits can be sustained over the longer term. Methods: Following PRISMA guidelines, Scopus, PsycINFO, Medline, PubMed and Embase databases were searched. Studies including a measure of self-compassion and a self-compassion intervention reporting weight management outcomes were included. Studies in populations living with an eating disorder were excluded. The Quality Criteria Checklist from the American Dietetic Association was used to assess study quality. Prospero Registration #CRD42019146707. Results: Of the 9082 records screened, a total of 20 studies met inclusion criteria. Seventeen studies reported significant increases in self-compassion post-intervention. Improvements were also found for eating behaviours (15 of 18), physical activity behaviours (6 of 9), and weight loss (6 of 11). The majority of improvements were maintained at follow-up, except for physical activity behaviours (1 of 7). Conclusion: Self-compassion interventions tailored to weight management outcomes demonstrate efficacy with increasing self-compassion post-intervention. Methodological weaknesses and questions about the maintenance of any improvements in weight management outcomes limit our ability to make strong conclusions. However, there is promise and clear relevance for including self-compassion interventions to enhance weight management outcomes; directions for improved intervention and study design are given.

Background Motherhood is a time of intense physical, psychological, and identity transformation, and body dissatisfaction may emerge through the process of pregnancy, birth, and adaptation to parenting. We present a feasibility trial of the Body Confident Mums Challenge, a program developed by adapting existing, effective interventions that focus on self-compassion and appreciation of body functionality to be specific to mothers. Methods The program was delivered using the social learning function in a closed Facebook group. Qualitative evaluation of evidence of change was conducted by gathering individual written reflections posted during the challenge (n = 120). Feasibility and acceptability was determined using a feedback survey (n = 22). Results Participant’s reflective posts indicated that they were embracing self-compassion, and de-prioritising body image concerns during the challenge. Feedback indicated that the program was mostly feasible and acceptable for mothers, with recommendations from some participants relating to slowing the pace of content delivery and reducing the time commitment of the Challenge. Conclusions The social media environment may therefore be a useful setting in which to implement brief intervention programs to improve body image and wellbeing.

Meta-analyses of DBT and other third-wave psychotherapies (e.g., acceptance and commitment therapy, mindfulness-based interventions) have not found these treatments to be superior to active comparisons or CBT [95], but they may have promise for eating disorder prevention by reducing eating disorder risk factors like disordered eating [i.e., binge eating (e.g., of lower frequently than required for a clinical diagnosis), disinhibited/uncontrolled eating, or emotional eating behaviors] and body image concerns [96]. There also is growing interest in evaluating DBT using guided selfhelp versions for the treatment of BED [97,98]. ...

Purpose of Review Binge eating disorder (BED) is characterized by recurrent binge eating episodes (i.e., eating an objectively large amount of food accompanied by a sense of loss of control while eating) in the absence of regular compensatory behavior. BED follows a chronic course marked by significant dysfunction and impairment. This review focuses on advances in the understanding of BED, including its diagnosis, correlates, risk factors, and treatment, with particular attention to the past 5 to 8 years. Recent Findings BED remains the most common eating disorder in the USA and globally. BED occurs across the lifespan and among diverse gender, racial, and ethnic groups. Risk for and maintenance of BED results from multiple psychological, biological, and sociocultural factors. First-line treatment for reducing binge eating is cognitive behavioral therapy, with efficacy for interpersonal psychotherapy as well. Lisdexamfetamine is an FDA-approved medication for moderate to severe cases of BED. Summary Even with advances in its diagnosis and treatment, better assessment and understanding of BED in diverse gender, racial, and ethnic populations is needed. Studies of shared risk factors underlying BED and comorbid disorders may lead to a greater understanding of mechanisms for intervention. Future research should prioritize evaluating the implementation of established treatments among populations in need, as well as establishing new interventions that can be scaled for delivery in real-world settings. Given overlap between BED and overweight/obesity, a continued focus on developing treatments that effectively address binge eating and weight management is warranted.

This study aimed to (1) examine the unique role of mindfulness and self-compassion on eating disorder (ED) psychopathology and functional impairment, and (2) compare levels of mindfulness and self-compassion between health controls and individuals categorized with bulimia nervosa (BN), and binge-eating disorder (BED). Data were analyzed from 1101 community-based participants, of which 145 met criteria for BN, 150 for BED, and 286 for healthy controls. Results from a series of multiple regressions revealed that self-compassion accounted for substantially more variance in ED psychopathol-ogy and functional impairment than mindfulness in the total sample and across the three subgroups, at times explaining 20 times more variance than mindfulness. Results remained unchanged when excluding the mindfulness subscale from the Self-Compassion Scale. When comparing these variables across the three study groups, results showed that self-compassion and mindfulness levels were lowest in the BN group, followed by the BED group, and then the healthy control group. Findings overall suggest that non-judgmental awareness may be less important in explaining levels of ED psychopathology than the nature of one's interaction with emotionally charged, negative experiences. Findings also point to possible priority intervention targets in indicated prevention and treatment programs.

Disordered eating and body image concerns significantly impact a growing number of men. This systematic review assessed the evidence of the effectiveness of psychosocial interventions to improve body image and eating pathology in men. Searches were conducted in December 2022 in 13 databases (PsycINFO, MEDLINE, CINAHL Plus, AMED, PubMed, Scopus, Cochrane, EMBASE, ASSIA, British Nursing Index, Wiley and OpenGrey). Studies that quantitatively evaluated psychosocial interventions and reported pre-post body image or disordered eating outcomes in men aged 18 years and over were eligible. Articles including boys, uncontrolled designs, or not in English were excluded. Findings were narratively synthesised and presented according to intervention approach. Quality was assessed using EPHPP. Eight studies including six RCTs were reviewed. Five were assessed as being moderate quality and three as weak. Evidence from moderate quality studies suggested that dissonance-based interventions showed promising improvements in body image and disordered eating for up to six months post-intervention in men with and without body dissatisfaction. Evidence for media literacy and psychoeducational interventions was limited. Findings were limited by heterogeneity in outcome measures and homogeneity of participants preventing generalisability. Robust research with longer follow-ups is needed to confirm effectiveness.

Objective: Breast cancer patients often suffer from body image disturbance due to impairment of their body/appearance resulting from surgeries, other cancer treatments, and/or their complications. Cognitive-based interventions (CBIs) have recently been adopted for patients having breast cancer but their effects on improving body image are uncertain. This systematic review aimed to examine the effects of CBIs on body image in these patients, identify the optimal dose, characteristics, and/or component(s) of an effective intervention for these patients to inform future research and practice. Methods: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, ten online databases and five search engines were used to search for eligible studies. Quality appraisal of included studies and meta-analysis results were conducted using Rob 2 and Grading of Recommendations Assessment, Development and Evaluation profiler Guideline Development Tool, respectively. RevMan and comprehensive meta-analysis software were used to perform data analysis and synthesis. Results: Eleven eligible randomized controlled trials (RCTs) examining the effects of cognitive behavioral, acceptance and commitment, mindfulness, and self-compassion therapies were reviewed. Results of the meta-analysis showed that CBIs significantly reduced negative body image perception (Standardised Mean Difference, SMD = -0.49, 95% confidence interval [CI], [-0.87, -0.11], I 2 = 81%, 6 RCTs, 758 participants), when compared to the control groups (mainly usual care) at immediately post-intervention; in which, CBT-based (SMD = -0.37, 95% CI (-0.60, -0.13), I 2 = 0%) and group-based (SMD = -0.38, 95% CI (-0.62, -0.13), I 2 = 0%) programs had more consistent and significant effects. Conclusions: In view of the highly heterogeneous and limited RCTs identified, high-quality controlled trials of CBIs for improving the body image of patients having breast cancer are suggested. Systematic review registration: PROSPERO, CRD42021259173.

Unlabelled: The COVID-19 pandemic lockdown restrictions posed unique challenges for people living with eating disorders (EDs), particularly relating to social isolation and changes in treatment access. However, less is known about the experience of lockdown for people 'in recovery' from EDs or disordered eating (DE) (i.e., with an ED/DE history). This study explored: (i) how people with a self-reported ED/DE history responded to and managed the experience of lockdown, specifically in relation to their recovery, and (ii) coping strategies for the management of recovery. Semi-structured interviews were conducted between June and August 2020 with 20 adults with a self-reported ED/DE history living in the UK. Data were analysed using inductive thematic analysis within a critical realist framework. Three overarching themes were identified: (1) Seeking safety and stability during a pandemic, (2) Lockdown prompting realisations about recovery, and (3) Exploring self-compassion as a more adaptive approach. While most participants experienced a resurgence in ED symptoms during lockdown, many reflected on the successful management of these as reinforcing their recovery. These findings have important implications for understanding ED recovery, in addition to informing interventions to better promote recovery during the COVID-19 pandemic and beyond.

Recent studies have found increasing rates of overweight and obesity in bulimia nervosa (BN). However, the relationships between body mass index (BMI) and BN symptoms and other clinically relevant constructs are unknown. Participants (N = 152 adults with BN) were assigned to three groups by BMI: group with no overweight or obesity (NOW-BN; BMI <25; N = 32), group with overweight (OW-BN; BMI ≥25 and <30; N = 66), and group with obesity (O-BN; BMI ≥30; N = 54). We compared the groups on demographics, diet and weight histories, body esteem, BN symptoms, and depression using chi square, analysis of variance, analysis of covariance, and Poisson regression models. The O-BN group was older (d = 0.57) and OW-BN and O-BN groups had greater proportions of race/ethnic minorities than NOW-BN group. The O-BN group was significantly younger at first diet (d = 0.41) and demonstrated significantly higher cognitive dietary restraint (d = 0.31). Compared to NOW-BN, O-BN participants had lower incidence of objective binge eating (incidence rate ratio [IRR] = 4.86) and driven exercise (IRR = 7.13), and greater incidence of vomiting (IRR = 9.30), laxative misuse (IRR = 4.01), and diuretic misuse (d = 2.08). O-BN participants also experienced higher shape (d = 0.41) and weight (d = 0.42) concerns than NOW-BN and OW-BN, although NOW-BN experienced higher shape (d = 0.44) and weight (d = 0.39) concerns than OW-BN. Groups did not differ on depression scores. These results were replicated when examining BMI as a continuous predictor across the full sample, with the exception of objective binge eating and driven exercise, which were not significantly associated with BMI. Individuals with BN and comorbid obesity have distinct clinical characteristics. Existing interventions may need to be adapted to meet clinical needs of these individuals.

Im letzten Jahrzehnt hat sich die Datenlage zur Behandlung von Essstörungen deutlich verbessert. In verschiedenen Meta-Analysen wurde die klinische Effektivität für die unterschiedlichen psychotherapeutischen Verfahren geprüft. Die Ergebnisse zeigen, dass nach wie vor die kognitive Verhaltenstherapie (KVT) als Behandlung der Wahl bei Essstörungen im Erwachsenenalter gilt; neben dem erfolgreichen Einsatz bei der Bulimia nervosa (BN) und der Binge-Eating-Störung (BES) zeigen Studien auch Erfolge bei der Behandlung der Anorexia nervosa (AN). Zudem mehren sich Hinweise, dass die KVT auch zur Behandlung Jugendlicher mit Essstörungen erfolgreich eingesetzt werden kann. Diese empirischen Nachweise sind Grundlage der Leitlinienempfehlungen zur Behandlung von Essstörungen.

Acceptance and Commitment Therapy (ACT) is increasingly used to treat eating disorders (EDs); however, the evidence for ACT with EDs has not been the subject of a systematic review. The current study reviews the evidence of ACT for EDs through January of 2022. PubMed and PsycInfo were searched for treatment studies using three or more ACT processes with adolescents or adults with anorexia nervosa, bulimia nervosa, binge eating disorder and purging disorder spectrum diagnoses. Studies focusing primarily on obesity, weight loss or body image were excluded. Twenty-two intervention studies were identified with a combined total of 674 participants. Five were randomized controlled trials. While the majority of studies focused on anorexia nervosa, these tended to be smaller studies of fewer participants. Results indicated that ACT may show reasonable efficacy for improvements in ED symptoms. However, most studies lacked sufficient methodological rigor and were weak on two or more components of the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies. Future directions and limitations of using the EPHPP for quality assessment of psychological interventions are discussed, as well as strengths and weaknesses of the evidence base in light of the recent ACBS Task Force Report on the Strategies and Tactics of Contextual Behavioral Science Research.

Dialectical behavioural therapy (DBT) has become the gold standard in the treatment of patients with borderline personality disorder. This therapy includes the combination of stance and techniques, which are characterized by the dialectic of acceptance and change. In the meantime, this method has also been successfully applied to other psychiatric disorders. In the case of anorexia nervosa - a disorder with a tendency to chronification and a considerably increased mortality risk - the work on treatment motivation increases. Traditional concepts in clinics are increasingly being questioned and tested for their suitability for everyday use. Here, DBT offers a set of tools with which positive experiences of effectiveness have already been made in some clinics. Evidence based on randomized controlled trials is still lacking. In this article, the basic principles of DBT treatment for adolescent patients with anorexia nervosa are explained and experiences with the treatment concept are reported.

Purpose: For patients with eating disorders (EDs), early engagement in care is usually considered a positive prognostic factor. The aim of the study was to investigate how a single-day intervention devoted to early, brief, experiential exposure to a variety of psychotherapy approaches might support commitment to change and the decision to engage in care in patients with EDs. Methods: One hundred and sixty-nine adult outpatients newly diagnosed with an ED took part in a single-day workshop for groups of up to ten patients, where they experienced eight psychotherapeutic approaches. Motivation to change care and level of insight were assessed at baseline and 10 days after the intervention. Results: Motivation and commitment to take active steps toward change (expressed by the “Committed Action” composite score) signifcantly improved after the intervention (p<0.001), and a signifcant number of patients specifcally moved from “contemplation” to “action” stage (p<0.001). The improvement of motivation to change was signifcantly associated with an increase in insight capacity (p<0.001), and this increase was observed for almost all related dimensions such as recognition of illness or awareness of need for psychological treatment. Conclusion: A single-day session devoted to experiencing a range of group psychotherapies increased patients’ insight and motivation to actively engage in care. To confrm potential longer-term benefts of this intervention, further studies are needed to explore the contribution of each approach and process specifcally involved in patients' increased motivation for care, as well as the clinical characteristics of patients associated with better outcomes.

Accumulating evidence suggests that the presence of shape/weight overvaluation in binge-eating disorder (BED) is associated with more severe psychopathology and impairment. To further inform the role of the overvaluation construct in BED, we examined whether those with and without shape/weight overvaluation differ on four core processes that underpin the contextual behaviour therapies: distress tolerance, self-compassion, mindfulness, and experiential avoidance. These four processes were investigated as each are considered important change mechanisms in contextual behavioural therapies and are either compatible or incompatible with the emotion dysregulation known to precipitate binge eating. Participants were categorized into one of four study groups: probable BED with overvaluation (n = 60); probable BED without overvaluation (n = 108); obese control (n = 59); healthy control (n = 123). Analyses of covariance showed that the probable BED with overvaluation group reported lower levels of self-compassion and distress tolerance, and higher levels of experiential avoidance than the three other groups. The probable BED without overvaluation group did not differ to control groups on these processes, except experiential avoidance levels. Findings highlight potentially important intervention targets and constructs among a subgroup of individuals with BED.

The ongoing coronavirus (COVID-19) pandemic and attendant lockdown mandates may have detrimental effects on body image outcomes, which in turn highlights the importance of identifying protective factors. Here, we examined associations between COVID-19-related stress and body image disturbance, as well as the potential mediating and moderating role of self-compassion. During the third lockdown in the United Kingdom, we asked an online sample of adults (N = 600) to complete measures of COVID-19-related stress, body image disturbance, and self-compassion. Mediation analysis showed that higher COVID-19-related stress was significantly associated with greater body image disturbance, and that this relationship was mediated by self-compassion. In contrast, self-compassion did not significantly moderate the effects of stress on body image disturbance. These results suggest that promoting greater self-compassion may be a viable means of mitigating adverse outcomes from the COVID-19 pandemic on body image disturbance.

Introduction: The past several years have witnessed a significant increase in interest among the public in mindfulness with an unmistakable growth in the scientific literature investigating mindfulness-based therapies. A myriad of therapeutic uses of mindfulness have been studied. Given this burgeoning interest, the authors' objective was to conduct a broad-sweeping bibliometric analysis over the past two decades to describe overarching trends in the publications of randomized controlled trials (RCTs) investigating mindfulness to broadly identify both strengths and gaps in this field and inform a strategic plan for further advancing this research area. Materials and Methods: The authors retrieved mindfulness-focused RCTs available on PubMed in the past two decades (2000-2019). They synthesized the literature with respect to publication numbers, countries of publication, journal type, areas of research focus, characteristics of study designs, sample size, and trends in remote intervention delivery. Results: The resulting 1389 publications represent a near exponential growth trend over the past 20 years. Publications from the top three countries (the United States, the United Kingdom, and the Netherlands) with the highest productivity accounted for 60% of total number of publications. The most published modalities include acceptance-based therapy (n = 260), mindfulness-based stress reduction (n = 238), mindfulness-based cognitive therapy (n = 174), and dialectical behavior therapy (n = 82). Stress, depression, anxiety, pain, cancer, diet/healthy eating, and sleep were the most common major areas of focus. Studies included active (46%) or inactive controls (44%), and increasingly more studies with both types of controls (10%). The top 10 journals that published the most mindfulness RCTs were from behavioral sciences and psychiatry or psychology. There were 187 RCTs utilizing remote delivery, with 146 (87.1%) in the most recent 5 years. Conclusion: Publications of mindfulness-focused RCTs show a continuous increasing trend. Mindfulness research from non-Western countries and studies published in biomedical journals were less prevalent and potentially represent future opportunities. Trends of studies with both inactive and active controls support an overall advancement in research methodology. There has been a significant expansion of studies of remotely delivered mindfulness interventions. Future research might consider evaluation of a broader range of modalities and further examine optimal delivery formats.

Objective Shame is broadly implicated in the development and maintenance of eating pathology. However, the relationship between shame and binge eating symptoms specifically is less clear. This review aimed to clarify what types of shame are associated with binge eating symptoms, and the antecedents and maintenance factors in these relationships. Method A systematic search for quantitative and qualitative empirical studies was conducted to identify evidence of the relationship between shame and binge eating symptoms. Altogether, 270 articles were identified and screened for eligibility in the review. Results Results of the relevant empirical studies (n = 31) identified several types of shame associated with binge eating pathology: (i) internal shame, (ii) external shame, (iii) body shame, and (iv) binge eating-related shame, as well as several mechanisms and pathways through which shame was associated with binge eating symptoms. Discussion Drawing from the research findings, this review presents an original, integrated model of the cyclical shame-binge eating relationship. Clinical interventions that might break this cycle are discussed, as well as methodological weaknesses which limit causal inferences and important areas of future research.

Objective: Although maladaptive exercise (ME) is widely recognized as a clinical feature in transdiagnostic eating disorders, less is known about psychosocial factors that give rise to and perpetuate this behavior. This systematic review aimed to examine the empirical status of this association. Method: We reviewed 46 full text articles examining longitudinal associations between psychosocial variables and ME. Results: Eighteen studies met full inclusion criteria. Based on our qualitative synthesis, evidence suggests reasonably consistent associations between early concern with weight and shape, and negative affect on later development of ME. Discussion: Inconsistent and insufficient assessment of ME across a majority of studies underscores caution in interpretation of results, but guides important discussion for future clinical and research efforts.

Body image flexibility refers to the ability to openly experience thoughts or feelings about the body without acting on them or trying to change them. Accumulating evidence has demonstrated that body image flexibility is connected to numerous adaptive processes, and that it is sensitive to change during psychological interventions. However, a quantitative synthesis of empirical research on body image flexibility is lacking. We conducted the first meta-analysis on body image flexibility and its correlates. Sixty-two studies were included. Random effects meta-analyses were conducted on 19 psychological correlates, divided into three clusters: eating and body image disturbances, positive body-related and general psychological constructs, and general psychopathology. Meta-analyses showed inverse correlations between body image flexibility and each construct within the eating and body image disturbances cluster (rs= −.45 to −.67), and the general psychopathology cluster (rs= −.37 to −.58). Body image flexibility was positively associated with each positive psychology construct (rs = .23 – .58). Men reported higher levels of body image flexibility than women (d = 0.32). Psychological interventions were more effective than control groups at enhancing body image flexibility in randomized controlled trials (d = 0.42). Findings confirm that body image flexibility is consistently connected to indices of mental health, and that it can be enhanced during psychological interventions.

In response to questions regarding the scientific basis for mindfulness-based interventions (MBIs), we evaluated their empirical status by systematically reviewing meta-analyses of randomized controlled trials (RCTs). We searched six databases for effect sizes based on four or more trials that did not combine passive and active controls. Heterogeneity, moderators, tests of publication bias, risk of bias, and adverse effects were also extracted. Representative effect sizes based on the largest number of studies were identified across a wide range of populations, problems, interventions, comparisons, and outcomes (PICOS). A total of 160 effect sizes were reported in 44 meta-analyses (k = 336 RCTs, N = 30,483 participants). MBIs showed superiority to passive controls across most PICOS (ds = 0.10–0.89). Effects were typically smaller and less often statistically significant compared with active controls. MBIs were similar or superior to specific active controls and evidence-based treatments. Heterogeneity was typically moderate. Few consistent moderators were found. Results were generally robust to publication bias, although other important sources of bias were identified. Reporting of adverse effects was inconsistent. Statistical power may be lacking in meta-analyses, particularly for comparisons with active controls. Because MBIs show promise across some PICOS, future RCTs and meta-analyses should build on identified strengths and limitations of this literature.

Adult women report significant body dissatisfaction yet are often overlooked in body image promotion programs. Although few venues afford opportune settings for intervening with adult women, the church serves as a regular meeting place for many in the South of the United States. This study tested a dissonance-based body image program, Reclaiming Beauty (RB), adapted for adult women in church settings. Six groups (n = 30) were led by two trained church leaders (peer-led) and three groups (n = 21) were led by a trained peer leader and a researcher (researcher-co-led). RB participants, aged 30–77 years (M = 53.1 ± 12.7), completed assessments pre-intervention, immediately post-intervention, and 6 months post-intervention. Waitlist-controls (n = 31) completed assessments at time intervals consistent with intervention participants. RB participants reported significantly decreased thin-ideal internalization, body surveillance, and eating psychopathology at post-intervention and at 6 months post-intervention relative to controls. RB participants also reported significantly increased body satisfaction immediately post-intervention relative to controls, but this was not significant at 6 months post-intervention. Peer-led groups outperformed researcher-co-led groups on body surveillance at 6 months, but RB conditions did not otherwise differ. Our findings provide preliminary support for the dissemination of a culturally-modified dissonance-based body image program to adult women in church settings.

We evaluated the effects of mindfulness-based eating awareness training (MB-EAT) as a treatment for weight maintenance and psychological symptoms post-bariatric surgery. MB-EAT is an evidence-based group intervention originally developed for individuals who binge eat. It consisted of eight weekly 2-h sessions and was an adjunct to treatment as usual for post-bariatric surgery care. Participants’ body mass index (BMI) was calculated, and they completed self-report measures of depression, anxiety, binge eating, emotional eating, emotion regulation, and mindfulness before and immediately after MB-EAT and at 4 months follow-up. Participants rated the helpfulness of each session and recorded the amount of time spent practicing mindfulness between sessions. Twenty-eight participants were recruited (100% female, mean age = 54.30), 22 completed the intervention, and comparable data was available for between 13 and 17 participants depending on the measure. Depression significantly decreased from pre to post MB-EAT (p = 0.04, Cohen’s d = 0.39), and at 4 months follow-up, emotion regulation was significantly improved (p = 0.04, Cohen’s d = 0.12). Trends toward improvement were observed in binge eating and emotional eating from pre- to post-MB-EAT and in emotional eating from pre to 4 months follow-up. Time spent practicing mindfulness between sessions was associated with statistically significant improvements in emotional eating in response to anger from pre- to post-MB-EAT (p = 0.05). The positive results from this pilot study highlight the feasibility of MB-EAT for addressing eating problems and mental health symptoms in bariatric surgery patients.

This study examined the effects of a mindful eating intervention on health-related outcomes. Thirty-six obese, post-menopausal women were randomized to a 6-week mindful eating and living (MEAL) intervention or an active control group (CONT), consisting of nutritional counseling, goal setting, and group support. Additionally, there were ten monthly refreshers. Weight, body mass index (BMI), waist-hip ratio (WHR), binge eating, interleukin-6 (IL-6), and C-reactive protein (CRP) were assessed at baseline and four follow-up periods up to 1 year. Multilevel analyses showed that the MEAL group had reductions in weight, BMI, WHR, binge eating, IL-6, and CRP, and the CONT group had reductions in weight, BMI, and binge eating. The reductions in IL-6 and CRP were greater for the MEAL as compared with the CONT group. This study suggests that a mindfulness-based eating intervention may have various health benefits in post-menopausal women who are obese.

Weight self-stigma is a promising target for innovative interventions seeking to improve outcomes among overweight/obese individuals. Preliminary research suggests acceptance and commitment therapy (ACT) may be an effective approach for reducing weight self-stigma, but a guided self-help version of this intervention may improve broad dissemination. This pilot open trial sought to evaluate the potential acceptability and efficacy of a guided self-help ACT intervention, included coaching and a self-help book, with a sample of 13 overweight/obese individuals high in weight self-stigma. Results indicated a high degree of program engagement (77% completed the intervention) and satisfaction. Participants improved on outcomes over time including weight self-stigma, emotional eating, weight management behaviors, health-related quality of life, and depression. Although not a directly targeted outcome, participants improved on objectively measured weight, with an average of 4.18 pounds lost over 7 weeks, but did not improve on self-reported weight at 3-month follow-up. Processes of change improved over time, including psychological inflexibility, valued action and reasons to lose weight. Coaching effects indicated greater retention and improvements over time with one coach vs. the other, suggesting characteristics of coaching can affect outcomes. Overall, these results provide preliminary support for the acceptability and efficacy of a guided self-help ACT program for weight self-stigma. Implications of these results and how to address clinical challenges with guided self-help are discussed.

Background Middle-aged women are at risk of weight gain and associated comorbidities. Deliberate restriction of food intake (dieting) produces short-term weight loss but is largely unsuccessful for long-term weight management. Two promising approaches for the prevention of weight gain are intuitive eating (ie, eating in accordance with hunger and satiety signals) and the development of greater psychological flexibility (ie, the aim of acceptance and commitment therapy [ACT]). Objectives This pilot study investigated the usage, acceptability, and feasibility of “Mind, Body, Food,” a Web-based weight gain prevention intervention prototype that teaches intuitive eating and psychological flexibility skills. Methods Participants were 40 overweight women (mean age 44.8 [standard deviation, SD, 3.06] years, mean body mass index [BMI] 32.9 [SD 6.01] kg/m², mean Intuitive Eating Scale [IES-1] total score 53.4 [SD 7.46], classified as below average) who were recruited from the general population in Dunedin, New Zealand. Module completion and study site metrics were assessed using Google Analytics. Use of an online self-monitoring tool was determined by entries saved to a secure online database. Intervention acceptability was assessed postintervention. BMI, intuitive eating, binge eating, psychological flexibility, and general mental and physical health were assessed pre- and postintervention and 3-months postintervention. Results Of the 40 women enrolled in the study, 12 (30%) completed all 12 modules (median 7.5 [interquartile range, IQR, 2-12] modules) and 4 (10%) used the self-monitoring tool for all 14 weeks of the intervention period (median 3 [IQR 1-9] weeks). Among 26 women who completed postintervention assessments, most women rated “Mind, Body, Food” as useful (20/26, 77%), easy to use (17/25, 68%) and liked the intervention (22/25, 88%). From pre- to postintervention, there were statistically significant within-group increases in intuitive eating (IES-2 total score P<.001; all IES-2 subscale scores: P ≤.01), psychological flexibility (P=.01), and general mental health (P<.001) as well as significant decreases in binge eating (P=.01). At the 3-month follow-up, IES-2 improvements were maintained, and there were further improvements in binge eating (P<.001) and general mental health (P=.03), and a marginal yet nonsignificant tendency for further improvement in psychological flexibility (P=.06). There were no significant within-group changes in BMI from pre- to postintervention and postintervention to 3-month follow-up (P=.46 and P=.93, respectively). Conclusions The “Mind, Body, Food” prototype Web-based intervention is appealing to middle-aged women and may be a useful tool to help women learn intuitive eating and ACT skills, reduce binge eating, and maintain weight over 3 months. Further work to improve the user experience and engagement is required before testing the online intervention in a randomized controlled trial.

Background Chronic pain patients increasingly seek treatment through mindfulness meditation. PurposeThis study aims to synthesize evidence on efficacy and safety of mindfulness meditation interventions for the treatment of chronic pain in adults. Method We conducted a systematic review on randomized controlled trials (RCTs) with meta-analyses using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Quality of evidence was assessed using the GRADE approach. Outcomes included pain, depression, quality of life, and analgesic use. ResultsThirty-eight RCTs met inclusion criteria; seven reported on safety. We found low-quality evidence that mindfulness meditation is associated with a small decrease in pain compared with all types of controls in 30 RCTs. Statistically significant effects were also found for depression symptoms and quality of life. Conclusions While mindfulness meditation improves pain and depression symptoms and quality of life, additional well-designed, rigorous, and large-scale RCTs are needed to decisively provide estimates of the efficacy of mindfulness meditation for chronic pain.

Introduction: Schizophrenia and psychotic disorders are chronic conditions. Although antipsychotic medicationsare the first line of treatment, many patients continued to have symptoms. Acceptance and Commitment Therapy(ACT) is a therapy that applies mindfulness to teach patients accepting the existence of symptoms rather than avoidthem. A meta-analysis was conducted to measure the efficacy of ACT in treatment of psychosis.Methods: A systematic review search was conducted using the following keywords: "acceptance andcommitment therapy", "randomized", "clinical trials", "psychosis"," schizophrenia", and "major depressive disorderAND psychosis". All studies were read by two authors and checked for eligibility. Studies were included if randomlyallocate to ACT or usual treatment (TAU), and psychosis as diagnosis. Mantel and Haenszel approach was used todetermine the heterogeneity in the study. For quantitative outcomes, standardized mean difference between ACTand TAU was used to summarize effect size, while relative risk was used for categorical outcomes along with 95%confidence interval.Results: 217 studies were identified. 92 studies were selected for review after removing the duplications. Atotal of 4 studies were included in quantitative-synthesis. The mean age for the participants was 38 years of age.Regarding treatment outcomes, there was a significant difference between the two arms in the degree of change ofnegative symptoms (p=0.008), but the difference was not significant for positive symptoms. There was a reduction ofre-hospitalization rate at 4 months in ACT compared to TAU in participants with psychosis.Conclusions: ACT is a promising adjunctive therapy for patient with psychosis.

Introduction: Binge and loss of control (LOC) eating are significant concerns among many adolescents and are associated with poor physical, social, and psychological functioning. Black girls appear to be particularly vulnerable to binge and LOC eating. Yet, empirically validated, culturally sensitive treatments for these disordered eating behaviors are not well established. This investigation examined satisfaction, feasibility, and preliminary outcomes of a binge eating intervention for ethnically diverse adolescent girls. Methods: Participants were 45 girls (age 13-17years; 44.4% white, 42.2% black) randomized into a dialectical behavior therapy (DBT)-based intervention (Linking Individuals Being Emotionally Real, LIBER8) or a weight management group (2BFit). Following each meeting, participants completed satisfaction measures, and therapists assessed intervention feasibility. Participants also completed assessments of eating behavior and related psychological constructs at baseline, immediately following the intervention, and at 3-month follow-up. Results: Descriptive statistics indicated that LIBER8 was feasible, and participants were highly satisfied with this intervention. Significant reductions in eating disorder cognitions, dietary restraint, and eating in response to negative affect were observed for participants in both groups, with no differences between LIBER8 and 2BFit. Discussion: The acceptability and feasibility of LIBER8 and associated reductions in emotional eating show promise in ameliorating binge eating and provide insight into multiple options for treating this challenging eating concern.

Assessment in clinical psychology typically relies on global retrospective self-reports collected at research or clinic visits, which are limited by recall bias and are not well suited to address how behavior changes over time and across contexts. Ecological momentary assessment (EMA) involves repeated sampling of subjects' current behaviors and experiences in real time, in subjects' natural environments. EMA aims to minimize recall bias, maximize ecological validity, and allow study of microprocesses that influence behavior in real-world contexts. EMA studies assess particular events in subjects' lives or assess subjects at periodic intervals, often by random time sampling, using technologies ranging from written diaries and telephones to electronic diaries and physiological sensors. We discuss the rationale for EMA, EMA designs, methodological and practical issues, and comparisons of EMA and recall data. EMA holds unique promise to advance the science and practice of clinical psychology by shedding light on the dynamics of behavior in real-world settings.

Binge eating involves rapidly and uncontrollably eating a large amount of food in a short time period. Research suggests that binge eating is common among people seeking bariatric 1 (weight-management) services with prevalence rates upwards of 50 %. Binge eating is associated with poorer weight loss and weight regain after bariatric services or alternative attempts at weight loss [1, 2]. Given the high rates of binge eating among people seeking bariatric services and its negative impact on weight-loss outcomes [1-3], targeting binge eating in patients seeking bariatric services may be useful to enable optimal treatment response. However, programs aimed at targeting binge eating are not routinely offered in bariatric programs. This manuscript describes the implementation and evaluation of a targeted intervention for binge eating among a group of patients accessing bariatric services. The intervention used in the present study was adapted from Linehan's [4] manualized dialectical behavior therapy (DBT) and Safer, Telch, and Chen's [5] manualized dialectical behavior therapy for binge eating (DBT-BE). The theory underlying this treatment is based upon the affect regulation model that suggests binge eating is used in an attempt to manage painful or unpleasant emotional states [6, 7]. Available evidence suggests that DBT-BE is effective in reducing binge eating among community-dwelling, adults with eating disorders [8]. However, to date, no research has tested whether DBT-BE is effective in reducing binge eating among patients seeking bariatric services. The present study addresses this gap by testing the impact that a 10-week DBT-BE skills group has on binge eating and associated psychosocial functioning among patients seeking bariatric services. We hypothesized binge eating and associated psychosocial functioning would improve following participation in the DBT-BE skills group.

Mindfulness-based interventions are increasingly used to treat binge eating. The effects of these interventions have not been reviewed comprehensively. This systematic review and meta-analysis sought to summarize the literature on mindfulness-based interventions and determine their impact on binge eating behavior. PubMED, Web of Science, and PsycINFO were searched using keywords binge eating, overeating, objective bulimic episodes, acceptance and commitment therapy, dialectical behavior therapy, mindfulness, meditation, mindful eating. Of 151 records screened, 19 studies met inclusion criteria. Most studies showed effects of large magnitude. Results of random effects meta-analyses supported large or medium-large effects of these interventions on binge eating (within-group random effects mean Hedge’s g = −1.12, 95 % CI −1.67, −0.80, k = 18; between-group mean Hedge’s g = −0.70, 95 % CI −1.16, −0.24, k = 7). However, there was high statistical heterogeneity among the studies (within-group I 2 = 93 %; between-group I 2 = 90 %). Limitations and future research directions are discussed.

Background: The current study presents the results of a meta-analysis of 39 randomized controlled trials on the efficacy of ACT, including 1,821 patients with mental disorders or somatic health problems. Methods: We searched PsycINFO, MEDLINE, and the Cochrane Central Register of Controlled Trials. Information provided by the Association of Contextual Behavioral Science (ACBS) community was also included. Statistical calculations were conducted using Comprehensive Meta-Analysis software. Study quality was rated using a methodology rating form. Results: ACT outperformed control conditions (Hedges’s g = 0.57) at post-treatment and follow-up, in completer and intent-to-treat analyses for primary outcomes. ACT was superior to waitlist (Hedges’s g = 0.82), to psychological placebo (Hedges’s g = 0.51) and to TAU (Hedges’ g = 0.64). ACT was also superior on secondary outcomes (Hedges’s g = 0.30), life satisfaction/quality measures (Hedges’s g = 0.37) and process measures (Hedges’s g = 0. 56) when compared to control conditions. The comparison between ACT and established treatments (i.e., CBT) did not reveal any significant differences between these treatments (p = .140). Conclusions: Our findings indicate that ACT is more effective than treatment as usual or placebo and that ACT may be as effective in treating anxiety disorders, depression, addiction, and somatic health problems as established psychological interventions. More research that focuses on quality of life and processes of change is needed to understand the added value of ACT and its trans diagnostic nature.

Dialectical Behavior Therapy (DBT) has been shown to effectively target binge eating disorder (BED). This study pilots the effectiveness of group DBT for obese "emotional eaters" to reduce eating psychopathology and achieve weight maintenance. Thirty-five obese male and female emotional eaters receiving 20 group psychotherapy sessions of DBT adapted for emotional eating were assessed at end-of-treatment and 6 month follow-up for reductions in eating psychopathology and weight maintenance. DBT resulted in significant reductions in emotional eating and other markers of eating psychopathology at the end-of-treatment that were maintained at follow-up. The drop-out rate was very low, with only 1 participant dropping from treatment. Thirty-three (94%) of the sample provided data at every assessment point. Of these, 80% achieved either weight reduction or weight maintenance after treatment and throughout the follow-up period. The effect size for weight reduction was small. This pilot study demonstrates group DBT targeting emotional eating in the obese to be a highly acceptable and effective intervention for reducing eating related psychopathology at both at end-of-treatment and during follow-up. The ability of DBT to limit the upward trajectory of weight gain in obese patients with high degrees of emotional eating suggests that DBT may also help limit the increase or even prevent onset of obesity related morbidity in these patients.

Objective To examine temporal trends in the burden of eating disorder (ED) features, as estimated by the composite of their prevalence and impact upon quality of life (QoL) over a period of 10 years. Methodology Representative samples of 3010 participants in 1998 and 3034 participants in 2008 from the South Australian adult population were assessed for endorsement of ED features (objective binge eating, extreme dieting, and purging were assessed in both years; subjective binge eating and extreme weight/shape concerns were also assessed in 2008) and QoL using the Medical Outcomes Study Short Form (SF-36). Principal Findings From 1998 to 2008 significant increases in the prevalence of objective binge eating (2.7% to 4.9%, p<0.01) and extreme dieting (1.5% to 3.3%, p<0.01), but not purging, were observed. Lower scores on the SF-36 were significantly associated with endorsement of any of these behaviors in both 1998 and 2008 (all p<0.001). No significant difference was observed in the effect of the endorsement of these ED behaviors on QoL between 1998 and 2008 (all p>0.05). Multiple linear regressions found that in 1998 only objective binge eating significantly predicted scores on the mental health summary scale of the SF-36; however, in 2008 extreme weight/shape concerns, extreme dieting, and subjective binge eating were also significant predictors. Objective binge eating and extreme dieting were significant predictors of scores on the physical health summary scale of the SF-36 in both 1998 and 2008. Conclusions and Significance The prevalence of ED behaviors increased between 1998 and 2008, while their impact on QoL remained stable. This suggests an overall increase in the burden of disordered eating from 1998 to 2008. Given that binge eating and extreme dieting predict impairment in QoL, the necessity of interventions to prevent both under- and over-eating is reinforced.

Mindfulness and acceptance-based approaches to the treatment of clinical problems are accruing substantial empirical support. This article examines the application of these approaches to disordered eating. Theoretical bases for the importance of mindfulness and acceptance in the treatment of eating problems are reviewed, and interventions for eating problems that incorporate mindfulness and acceptance skills are briefly described. Empirical data are presented from a pilot study of mindfulness-based cognitive therapy adapted for treatment of binge eating.

Although third-wave behaviour therapies are being increasingly used for the treatment of eating disorders, their efficacy is largely unknown. This systematic review and meta-analysis aimed to examine the empirical status of these therapies. Twenty-seven studies met full inclusion criteria. Only 13 randomized controlled trials (RCT) were identified, most on binge eating disorder (BED). Pooled within- (pre-post change) and between-groups effect sizes were calculated for the meta-analysis. Large pre-post symptom improvements were observed for all third-wave treatments, including dialectical behaviour therapy (DBT), schema therapy (ST), acceptance and commitment therapy (ACT), mindfulness-based interventions (MBI), and compassion-focused therapy (CFT). Third-wave therapies were not superior to active comparisons generally, or to cognitive-behaviour therapy (CBT) in RCTs. Based on our qualitative synthesis, none of the third-wave therapies meet established criteria for an empirically supported treatment for particular eating disorder subgroups. Until further RCTs demonstrate the efficacy of third-wave therapies for particular eating disorder subgroups, the available data suggest that CBT should retain its status as the recommended treatment approach for bulimia nervosa (BN) and BED, and the front running treatment for anorexia nervosa (AN) in adults, with interpersonal psychotherapy (IPT) considered a strong empirically-supported alternative.

Objective: Mindfulness is being promoted in schools as a prevention program despite a current small evidence base. The aim of this research was to conduct a rigorous evaluation of the .b ("Dot be") mindfulness curriculum, with or without parental involvement, compared to a control condition. Method: In a randomized controlled design, students (Mage 13.44, SD 0.33; 45.4% female) across a broad range of socioeconomic indicators received the nine lesson curriculum delivered by an external facilitator with (N = 191) or without (N = 186) parental involvement, or were allocated to a usual curriculum control group (N = 178). Self-report outcome measures were anxiety, depression, weight/shape concerns, wellbeing and mindfulness. Results: There were no differences in outcomes between any of the three groups at post-intervention, six or twelve month follow-up. Between-group effect sizes (Cohen's d) across the variables ranged from 0.002 to 0.37. A wide range of moderators were examined but none impacted outcome. Conclusions: Further research is required to identify the optimal age, content and length of mindfulness programs for adolescents in universal prevention settings. Trial registration: ACTRN12615001052527.

Objective: Scientific research into compassion has burgeoned over the past 20 years and interventions aiming to cultivate compassion towards self and others have been developed. This meta-analysis examined the effects of compassion-based interventions on a range of outcome measures. Method: Twenty-one randomized controlled trials (RCTs) from the last 12 years were included in the meta-analysis, with data from 1,285 participants analyzed. Effect sizes were standardized mean differences calculated using the difference in pre-post change in the treatment group and control group means, divided by the pooled pre-intervention standard deviation. Results: Significant between-group differences in change scores were found on self-report measures of compassion (d = 0.55, k = 4, 95% CI [0.33-0.78]), self-compassion (d = 0.70, k = 13, 95% CI [0.59-0.87]), mindfulness (d = 0.54, k = 6, 95% CI [0.38-0.71]), depression (d = 0.64, k = 9, 95% CI [0.45-0.82]), anxiety (d = 0.49, k = 9, 95% CI [0.30-0.68]), psychological distress (d = 0.47, k = 14, 95% CI [0.19-0.56]), and well-being (d = 0.51, k = 8, 95% CI [0.30-0.63]). These results remained when including active control comparisons. Evaluations of risk of bias across studies pointed towards a relative lack of publication bias and robustness of findings. However, the evidence base underpinning compassion interventions relies predominantly on small sample sizes. Conclusions: Future directions are provided for compassion research, including the need for improved methodological rigor, larger scale RCTs, increased specificity on the targets of compassion, and examination of compassion across the lifespan. Although further research is warranted, the current state of evidence highlights the potential benefits of compassion-based interventions on a range of outcomes.

Objective: To systematically review and quantify the effectiveness of Eating Disorder (ED) prevention interventions. Methods: Electronic databases (including the Cochrane Controlled Trial Register, MEDLINE, PsychInfo, EMBASE, and Scopus) were searched for published randomized controlled trials of ED prevention interventions from 2009 to 2015. Trials prior to 2009 were retrieved from prior reviews. Results: One hundred and twelve articles were included. Fifty-eight percent of trials had high risk of bias. Findings indicated small to moderate effect sizes on reduction of ED risk factors or symptoms which occurred up to three-year post-intervention. For universal prevention, media literacy (ML) interventions significantly reduced shape and weight concerns for both females (-0.69, confidence interval (CI): -1.17 to -0.22) and males (-0.32, 95% CI -0.57 to -0.07). For selective prevention, cognitive dissonance (CD) interventions were superior to control interventions in reducing ED symptoms (-0.32, 95% CI -0.52 to -0.13). Cognitive behavioural therapy (CBT) interventions had the largest effect size (-0.40, 95% CI -0.55 to -0.26) on dieting outcome at 9-month follow-up while the healthy weight intervention reduced ED risk factors and body mass index. No indicated prevention interventions were found to be effective in reducing ED risk factors. Conclusions: There are a number of promising preventive interventions for ED risk factors including CD, CBT and ML. Whether these actually lower ED incidence is, however, uncertain. Combined ED and obesity prevention interventions require further research.

This randomized-controlled trial aims to test the efficacy of a group intervention (Kg-Free) for women with overweight or obesity based on mindfulness, ACT and compassion approaches. The intervention aimed to reduce weight self-stigma and unhealthy eating patterns and increase quality-of-life (QoL). Seventy-three women, aged between 18 and 55 years old, with BMI ≥25 without binge-eating seeking weight loss treatment were randomly assigned to intervention or control groups. Kg-Free comprises 10 weekly group sessions plus 2 booster fortnightly sessions, of 2h30 h each. The control group maintained Treatment as Usual (TAU). Data was collected at baseline and at the end of the Kg-Free intervention. Overall, participants enrolled in Kg-Free found the intervention to be very important and helpful when dealing with their weight-related unwanted internal experiences. Moreover, when compared with TAU, the Kg-Free group revealed a significant increased health-related QoL and physical exercise and a reduction of weight self-stigma, unhealthy eating behaviors, BMI, self-criticism, weight-related experiential avoidance and psychopathological symptoms at post-treatment. Results for self-compassion showed a trend towards significance, whereas no significant between-groups differences were found for mindfulness. Taken together, evidence was found for Kg-Free efficacy in reducing weight-related negative experiences and promoting healthy behaviors, psychological functioning, and QoL.

This study examined the effectiveness of Kg-Free: an acceptance-, mindfulness- and compassion-based group intervention for women with overweight and obesity at post-treatment and 3-month follow-up and explored the psychological processes that underlie changes in quality of life, weight self-stigma, body mass index and emotional eating at post-treatment. Overall, 53 women completed Kg-Free. At post-treatment and 3-month follow-up, participants reported increased quality of life, mindfulness and self-compassion abilities and decreased weight self-stigma, emotional eating, shame, weight-related experiential avoidance, self-criticism and body mass index. Shame and self-criticism reductions were important mediators of changes in health-related outcomes, whereas weight-related experiential avoidance, mindfulness and self-compassion mediated changes in weight and eating-related outcomes.

Emotional eating is an important predictor of weight loss and weight regain after weight loss. This two part study's primary aim was to explore changes in emotional eating in a general population of individuals taking the Mindfulness Based Stress Reduction (MBSR) program, with a secondary aim to explore whether changes in mindfulness predicted changes in emotional eating. Self-reported survey data exploring these questions were collected before and after the intervention for two sequential studies (Study 1 and Study 2). While there were no control groups for either study, in both studies emotional eating scores following the MBSR were significantly lower than scores prior to taking the MBSR (p < 0.001; p < 0.001) In Study 2, changes in mindfulness were correlated with changes in emotional eating (r = 0.317, p = 0.004). These results suggest that MBSR may be an effective intervention for emotional eating, and that further research is warranted to examine effects on weight loss and maintenance.

Aims The standardised mean difference (SMD) is one of the most used effect sizes to indicate the effects of treatments. It indicates the difference between a treatment and comparison group after treatment has ended, in terms of standard deviations. Some meta-analyses, including several highly cited and influential ones, use the pre-post SMD, indicating the difference between baseline and post-test within one (treatment group). Methods In this paper, we argue that these pre-post SMDs should be avoided in meta-analyses and we describe the arguments why pre-post SMDs can result in biased outcomes. Results One important reason why pre-post SMDs should be avoided is that the scores on baseline and post-test are not independent of each other. The value for the correlation should be used in the calculation of the SMD, while this value is typically not known. We used data from an ‘individual patient data’ meta-analysis of trials comparing cognitive behaviour therapy and anti-depressive medication, to show that this problem can lead to considerable errors in the estimation of the SMDs. Another even more important reason why pre-post SMDs should be avoided in meta-analyses is that they are influenced by natural processes and characteristics of the patients and settings, and these cannot be discerned from the effects of the intervention. Between-group SMDs are much better because they control for such variables and these variables only affect the between group SMD when they are related to the effects of the intervention. Conclusions We conclude that pre-post SMDs should be avoided in meta-analyses as using them probably results in biased outcomes.

Objective: This systematic review evaluated the efficacy of universal, selective, and indicated eating disorder prevention. Method: A systematic literature search was conducted in Medline, PsycINFO, Embase, Scopus, and the Cochrane Collaboration Library databases to January 2016. Studies were included if they were randomized, controlled trials (RCT) and tested an eating disorder prevention program. We retrieved 13 RCTs of universal prevention (N = 3,989 participants, 55% female, M age = 13.0 years), 85 RCTs of selective prevention (N = 11,949 participants, 99% female, M age = 17.6 years), and 8 RCTs of indicated prevention (N = 510 participants, 100% female, M age = 20.1 years). Meta-analysis was performed with selective prevention trials. As there were a limited number of universal and indicated trials, narrative synthesis was conducted. Results: Media literacy had the most support for universal prevention. Most universal approaches showed significant modest effects on risk factors. Dissonance-based was the best supported approach for selective prevention. Cognitive-behavior therapy (CBT), a healthy weight program, media literacy, and psychoeducation, were also effective for selective prevention and effects were maintained at follow-up. CBT was supported for indicated prevention and effects were maintained at follow-up. Discussion: The modest effects for universal prevention were likely due to floor effects. The evidence for selective prevention suggests that empirically supported approaches should be disseminated on a wider basis. Our findings suggest CBT should be offered for indicated populations. Overall, results suggest efficacy of several prevention programs for reducing risk for eating disorders, and that wider dissemination is required. © 2016 Wiley Periodicals, Inc.
