Article
Previous research has shown a robust association between sudden gains (SGs) and treatment outcome in psychotherapy for various mental disorders including anorexia nervosa (AN). However, little is known about factors contributing to SGs. This study investigated the role of general change mechanisms in body-weight related SGs in AN. Data were drawn f...

Full-text available
Objective: The aim of this study was to examine the processes involved in a guided self-help (GSH) pre-treatment intervention (RecoveryMANTRA) for patients with anorexia nervosa (AN), by measuring the levels of patient/mentor Language Style Matching (LSM). RecoveryMANTRA was supported by student mentors or peer mentors (recovered individuals) over...
Article
Objective: Psychotherapy is the treatment of choice for anorexia nervosa (AN) but mechanisms of action are still largely unknown. Growing research suggests that synchrony between patient and therapist contributes to treatment success. Adding to this literature, this study examined the association between language style matching (LSM) among patient...
Article
Objective: Especially for adult patients with anorexia nervosa (AN), treatment response is generally low to moderate. The present study aimed to evaluate the efficacy of cognitive remediation therapy (CRT) as adjunctive treatment for AN regarding clinical and cognitive outcomes. Method: In this randomized controlled superiority trial, 167 adult and...
Article
Objective This study explored participants' experience of approach bias modification training (ABM) with transcranial Direct Current Stimulation (tDCS) for binge eating disorder (BED) within a randomised controlled trial (RCT). A subset of participants who completed the RCT were interviewed to attain feedback on treatment experience and outcomes....
Article
Full-text available
Objective Recent models of anorexia nervosa (AN) emphasise the role of reduced emotion recognition ability (ERA) in the development and maintenance of the disorder. However, methodological limitations impede conclusions from prior research. The current study tries to overcome these limitations by examining ERA with an audio-visual measure that focu...
Article
Full-text available
Objective: Very brief exposure to masked images of spider stimuli can facilitate approach behaviour towards spiders in fearful subjects. We hypothesized that a similar effect might occur for fear of food in patients with anorexia nervosa (AN), possibly offering a new treatment approach, with advantages over other methods of food exposure. Methods...
Article
Elevated consumption of sugar-sweetened beverages (SSBs) contributes to overweight and obesity. Automatic action tendencies like an approach bias might promote the consumption of SSBs. We investigated whether an Approach-Avoidance Training (AAT) reduces this approach bias and related behaviors like craving for and consumption of SSBs. Fifty-six hea...
Article
Full-text available
Most tasks for measuring automatic approach–avoidance tendencies do not resemble naturalistic approach–avoidance behaviors. Therefore, we developed a paradigm for the assessment of approach–avoidance tendencies towards palatable food, which is based on arm and hand movements on a touchscreen, thereby mimicking real-life grasping or warding movement...
Article
Full-text available
Background: Recent research has identified several cognitive biases in patients with eating disorders, such as a tendency to interpret ambiguous information about one's own body in a negative way. The so-called "negative interpretation bias" is considered to be a key factor in maintaining maladaptive cognitions and behaviors in eating disorders. S...
Article
Full-text available
Objective The two studies aimed to examine implicit affective evaluations of thin‐ideal and normal‐weight body shapes in women with anorexia nervosa (AN), taking identification with body shapes into account. Method In study 1, approach–avoidance bias for thin‐ideal and normal‐weight bodies was assessed in 40 women with AN and 40 healthy women by u...
Article
Regular physical activity is associated with better physical and mental health outcomes as well as higher quality of life. This pilot randomized controlled trial examined whether approach bias modification, an economical and easily accessible computerized cognitive training, could increase objectively and subjectively measured physical activity in...
Article
Objective Previous research has found increasing evidence for difficulties in emotion recognition ability (ERA) and social cognition in anorexia nervosa (AN), and recent models consider these factors to contribute to the development and maintenance of the disorder. However, there is a lack of experimental studies testing this hypothesis. Therefore,...

Full-text available
Introduction Binge eating disorder (BED) is a common mental disorder, closely associated with obesity. Existing treatments are only moderately effective with high relapse rates, necessitating novel interventions. This paper describes the rationale for, and protocol of, a feasibility randomised controlled trial (RCT), evaluating the combination of t...
Article
Impulsivity is a major component of various mental disorders. A short form of the Barratt Impulsiveness Scale-the BIS-15-assesses three facets of impulsivity: non-planning, motor, and attentional. A confirmatory factor analysis tested its factor structure composed of three first-order latent factors and a second-order impulsivity factor in 453 pati...

Article
Objective Bulimia nervosa (BN) and binge‐eating disorder (BED) are associated with poorly controlled approach behavior toward food resulting in binge eating. Approach bias modification (ABM) may reduce these automatic action tendencies (i.e., approach bias) toward food and may thus decrease binge eating and related symptoms. Method A total of 56 p...
Article
Objective Patients with anorexia nervosa (AN) often show difficulties in the perception, expression, and regulation of emotions and a strong avoidance of aversive feelings. According to psychobiological models, dietary restraint and accompanying weight loss may serve as a maladaptive mechanism of emotion regulation by attenuating aversive emotional...
Article
Full-text available
Individuals with bulimia nervosa (BN) or binge-eating disorder (BED) experience more frequent and intense food cravings than individuals without binge eating. However, it is currently unclear whether they also show larger food cue-induced increases in craving (i.e., food cue reactivity) than those without binge eating, as suggested by conditioning...
Data
Data set of the study reported in Meule, A., Küppers, C., Harms, L., Friederich, H.-C., Schmidt, U., Blechert, J., & Brockmeyer, T. (2018). Food cue-induced craving in individuals with bulimia nervosa and binge-eating disorder. PLoS ONE, 13(9), e0204151.
Article
Full-text available
Background: The aim of the study was a systematic review of studies evaluating psychotherapeutic treatment approaches in anorexia nervosa and to compare their efficacy. Weight gain was chosen as the primary outcome criterion. We also aimed to compare treatment effects according to service level (inpatient vs. outpatient) and age group (adolescents...
Article
A distorted body image and pronounced body dissatisfaction are hallmarks of anorexia nervosa (AN) that typically result in dietary restraint and compensatory behaviours. Cognitive biases such as negative interpretation bias are considered key maintaining factors of these maladaptive cognitions and behaviours. However, little attention has been paid...
Article
Strong implicit responses to food have evolved to avoid energy depletion but contribute to overeating in today's affluent environments. The Approach-Avoidance Task (AAT) supposedly assesses implicit biases in response to food stimuli: Participants push pictures on a monitor "away" or pull them near with a joystick that controls a corresponding imag...
Article
Background Anorexia nervosa (AN) is a disabling, deadly and costly mental disorder. Until recently, treatment recommendations were based on expert opinion and limited evidence. The aim of this systematic review is to synthesise recent evidence on established and emerging AN treatments and to forecast trends for future developments. Methods We syst...
Article
Background: Heightened sensitivity towards reward and insensitivity towards disadvantageous consequences may constitute a driving factor underlying unrestricted food intake and consequent weight gain in people with overweight and obesity. Therefore, the present study applied a behavioral economics approach to investigate the potential contribution...
Article
Objective: It is unclear whether observed memory impairment in anorexia nervosa (AN) depends on the semantic structure (categorized words) of material to be encoded. We aimed to investigate the processing of semantically related information in AN. Method: Memory performance was assessed in a recall, learning, and recognition test in 27 adult wom...
Article
Full-text available
Objective: Low inhibitory control and strong hedonic response towards food are considered to contribute to overeating and obesity. Based on previous research, the present study aimed at examining the potentially crucial interplay between these two factors in terms of long-term weight loss in people with obesity. Methods: BMI, inhibitory control...
Article
Full-text available
Background The core symptoms of bulimia nervosa (BN) and binge eating disorder (BED) are recurrent episodes of binge eating. Despite negative psychological and physical consequences, BN/BED patients show uncontrollable approach tendencies towards food. This cognitive bias occurs at an early stage of information processing. Cognitive bias modificati...
Article
Objective: Building on recent models of anorexia nervosa (AN) that emphasize the importance of impaired social cognition in the development and maintenance of the disorder, the present study aimed at examining whether women with AN have more difficulties with inferring other people's emotional and nonemotional mental states than healthy women. Me...
Article
Poor cognitive-behavioral flexibility is considered a trait marker in anorexia nervosa (AN) that can be improved by Cognitive Remediation Therapy (CRT). The present pilot study aimed at identifying changes in brain function potentially associated with CRT in AN. Data was obtained from a randomized, controlled trial. Twenty-four patients were assess...
Article
Full-text available
Several theories suggest that self-focused attention plays an important role in the maintenance of depression. However, previous studies have predominantly relied on self-report and laboratory-based measures such as sentence completion tasks to assess individual differences in self-focus. We present a prospective, longitudinal study based on a samp...
Article
Full-text available
Self-focused attention (SFA) is considered a cognitive bias that is closely related to depression. However, it is not yet well understood whether it represents a disorder-specific or a trans-diagnostic phenomenon and which role the valence of a given context is playing in this regard. Computerized quantitative text-analysis offers an integrative ps...
Article
Previous studies suggest that mood-incongruent processing constitutes an adaptive mood regulation strategy, and that difficulties in this process may contribute to the maintenance of depression. However, no study has yet examined whether mood-incongruent processing predicts the course and severity of clinical depression. To address this question, t...
Article
Even though people suffering from high levels of food craving are aware of the negative consequences of binge eating, they cannot resist. Automatic action tendencies (i.e. approach bias) towards food cues that operate outside conscious control may contribute to this dysfunctional behavior. The present study aimed to examine whether people with high...
Article
The aim of the present proof-of-concept study was to test a novel cognitive bias modification (CBM) programme in an analogue sample of people with subclinical bulimic eating disorder (ED) psychopathology. Thirty participants with high levels of trait food craving were trained to make avoidance movements in response to visual food stimuli in an impl...
Article
Background: Cognitive reactivity is the change in depressive thinking in response to negative mood. Previous research indicates that cognitive reactivity is an important variable in the etiology and course of depression. The present study tested which time interval after a negative mood induction is critical for the prediction of the depression ri...
Article
Although chronic depression is associated with lower global functioning and poorer treatment response than episodic depression, little is known about the differences between these two forms of depression in terms of psychological factors. Thus, the present study aimed at differentiating chronic and episodic depression regarding cognitive-behavioral...
Article
Background: In this meta-analysis we review the findings from neuropsychological studies on set-shifting in people with eating disorders (EDs) or overweight/obesity. Method: Four databases (PubMed, PsycINFO, PSYNDEX and Web of Science) were searched for eligible studies. Effect sizes (ESs) were pooled using random-effects models. Moderator analy...
Article
Mealtime support is a cornerstone of eating disorders (ED) inpatient and day-care treatment but has received only little attention in research so far and no valid recommendations are available for this type of intervention. Thus, the aim of the present study was to gather a comprehensive picture of how mealtime support is currently practiced in Ger...
Article
Full-text available
The anticipation of the pleasure derived from food intake drives the motivation to eat, and hence facilitate overconsumption of food, which ultimately results in obesity. Brain imaging studies provide evidence that mesolimbic brain regions underlie both general as well as food-related anticipatory reward processing. In light of this knowledge, the...
Article
Inefficient cognitive flexibility is considered a neurocognitive trait marker involved in the development and maintenance of anorexia nervosa (AN). Cognitive Remediation Therapy (CRT) is a specific treatment targeting this cognitive style. The aim of this study was to investigate the feasibility and efficacy (by estimating the effect size) of speci...
Article
The present study tested a theoretically derived link between rumination and depressive symptoms through behavioural avoidance and reduced motive satisfaction as a key aspect of positive reinforcement. Rumination, behavioural avoidance, motive satisfaction and levels of depression were assessed via self-report measures in a clinical sample of 160 p...
Article
Full-text available
The NMR-SF is the short form of the NMR Scale. The NMR-SF is a self-rating instrument to measure negative mood regulation expectancies. This construct is an important variable in the etiology and psychotherapy of mental disorders. The present study investigates the construct validity of the NMR-SF in 2 non-clinical samples and a sample of depressed...
Article
Theoretical models consider difficulties in emotion regulation (ER) as central trans-diagnostic phenomena across the spectrum of eating disorders (ED). However, there is a lack of studies directly comparing ED subtypes regarding ER problems. Furthermore, patients with anorexia nervosa-restricting type (AN-R) and patients with AN-binge/purge type (A...
Article
Food restriction and weight-loss have been proposed to represent pathogenic mechanisms of emotion regulation in anorexia nervosa (AN). However, there is a lack of studies empirically examining this hypothesis. Therefore, the present study compared 25 women with AN and 25 healthy control women (HC) regarding spontaneous emotional processing of autob...
Article
Full-text available
High ambivalence over the expression of emotions (AEE) has consistently been associated with high levels of depression in previous research. However, there is a lack of studies examining this construct and its associations in a clinical sample of patients with major depressive disorder (MDD). Therefore, the present study compared 76 MDD with 77 non...
Article
OBJECTIVE: This study examined the widely held but insufficiently studied hypothesis of autonomy disturbances in anorexia nervosa. METHOD: A total sample of 112 participants comprising patients with acute anorexia nervosa (AN), women recovered from anorexia nervosa (REC), clinical controls (CC), and healthy controls (HC) completed measures of depen...
Article
Emotion regulation (ER) difficulties have been considered to play an important role in the development and maintenance of various mental disorders such as depression and anorexia nervosa. However, previous research has failed to provide detailed insight into the disorder-specificity of ER difficulties. Therefore, the present study investigated spec...
Article
Impaired mood regulation has been considered to be a vulnerability factor for depression. However, there is a lack of studies specifically testing whether (a) negative mood regulation (NMR) expectancies and (b) emotion avoidance (EA) are associated with the risk for clinical depression. Therefore, the present study investigated these two specific f...
Article
Unlabelled: The aim of the present study was to examine the associations between self-esteem, motive satisfaction, and body weight in acute (acAN) and recovered (recAN) inpatients with anorexia nervosa (AN) and in healthy controls. Both acAN and recAN showed lower levels of self-esteem as compared with healthy controls but did not differ from each...
Article
Full-text available
There is substantial evidence supporting the hypothesis that cognitive reactivity is an important variable in the etiology of depression. However, there is a lack of studies examining possible mechanisms that underlie cognitive reactivity. The present study tested whether two specific mood regulation processes differentially appear in vulnerable an...
Article
Self-starvation, with concomitant weight loss, may serve as a dysfunctional behavior to attenuate negative affective states in anorexia nervosa (AN). A total of 91 participants composed of patients with acute AN, women recovered from AN, clinical controls with either depression or anxiety disorder, and healthy controls were tested on a measure of e...
