Family therapy for eating disorders (ED) is well-established and represents the treatment choice for ED in children and adolescents according to guidelines, with cognitive behavior therapy (CBT) as a second line treatment. There is limited knowledge about how these treatments work in routine clinical care. The goal of the present meta-analysis is t...
There are over 40 million displaced children and youth worldwide and there is a need promote their mental wellbeing. This study aimed to synthesize evidence regarding promotion interventions to increase wellbeing, resilience, and quality of life (primary outcomes), and prevention interventions to reduce internalizing and externalizing symptoms (sec...
Introduction:
In an uncontrolled study, we previously demonstrated the feasibility and preliminary efficacy of our virtual diabetes-specific version (Diabetes Body Project) of the eating disorder (ED) prevention program the Body Project. The aim of the current study was to evaluate further this program for women with type 1 diabetes (T1D) by asses...
The random-intercept cross-lagged panel model (RI-CLPM) is an extension of the traditional cross-lagged panel model. In RI-CLPM, prospective effects are estimated within rather than between individuals. In the present simulations, we found that RI-CLPM is susceptible to spurious findings when observed scores on the two variables are affected by com...
Objective
Cognitive behavior therapy (CBT) is a recommended treatment for eating disorders (ED) in adults given its evidence, mainly based on efficacy studies. However, little is known about how CBT works in routine clinical care. The goal of the present meta‐analysis is to investigate how CBT works for various ED when carried out in routine clinic...
Background
Eating disorders (EDs) are a group of mental illnesses associated with significant psychological and physiological consequences. Overall, only about one-fifth of individuals with EDs receive treatment and treatment is effective for only about one-third for those who receive care. The development and implementation of effective prevention...
Objective:

Background
There is a paucity of research on therapist competence development following extensive training in cognitive behavioural therapy (CBT). In addition, metacognitive ability (the knowledge and regulation of one’s cognitive processes) has been associated with learning in various domains but its role in learning CBT is unknown.
Aims
To inves...
Access to interventions that effectively reduce stress is limited and often costly. Lack of time, and stigma might also be significant barriers. This study examined the effectiveness of an Acceptance and Commitment Therapy (ACT)-based self-help book without therapist support for adults with moderate levels of stress, without psychiatric diagnoses....
In an anonymous online study (N = 824), we investigated the frequency of use of appearance and performance-enhancing drugs and supplements (APEDS) in a sample of young men (15–30 years) in Sweden, along with their self-reported eating disorder (ED) symptoms, drive for muscularity and sexual orientation. A total of 129 participants (16.1%) reported...
Each year, millions of people worldwide are forced to leave their homes. Many of those affected are families. There are already a considerable number of initiatives designed to support refugees who are resettling in new countries and cultures. However, few are promotive interventions aiming to support parents and thereby their children through the...
Offspring of parents with anxiety disorders have an increased risk of developing anxiety themselves. Very few studies have evaluated interventions aiming to prevent anxiety in offspring of anxious parents. This study was a small (N=40) randomized pilot study with three arms evaluating the feasibility of a novel parent support group for anxious pare...
We investigated whether brief non-judgmental focus on the details of one’s non-dominant hand might lead to changes in perception of its size, and if such a change would be related to central coherence, body dissatisfaction, or how much participants liked their hand. After two pilot experiments (N = 28 and N = 30 respectively: Appendix 1), a within-...
Psychiatric conditions in general, including eating disorders, are stigmatizing conditions. The stigma of eating disorders is even more pronounced among males. We conducted an anonymous, online survey to explore the feasibility of recruiting participants for collecting sensitive information, and the relation among eating disorders, drive for muscul...

We aimed to explore the occurrence of body-related mental images among females reporting a subjective sense of body dissatisfaction (study 1), and to investigate the potential efficacy of a single session of imagery rescripting (ImRS)...
Cognitive behavioral therapy (CBT) has strong research support for obsessive-compulsive disorder (OCD). However, less is known about how CBT performs when delivered in routine clinical care. A systematic review and meta-analysis was conducted of CBT for OCD in adults treated in routine clinical care. Ovid MEDLINE, Embase OVID, and PsycINFO were sys...
Background
Eating disorders (ED) are severe psychiatric conditions, characterized by decreased quality of life and high mortality. However, only a minority of patients with ED seek care and very few receive treatment. Internet-delivered cognitive behavioral therapy (ICBT) has the potential to increase access to evidence-based treatments.
Aims
The...
As evaluation of practitioners’ competence is largely based on self-report, accuracy in practitioners’ self-assessment is essential for ensuring high quality treatment-delivery. The aim of this study was to assess the relationship between independent observers’ ratings and practitioners’ self-reported treatment integrity ratings of Motivational int...

Methods:
An economic eval...
Introduction
Little is known about how early (eg, commencing antenatally or in the first 12 months after birth) obesity prevention interventions seek to change behaviour and which components are or are not effective. This study aims to (1) characterise early obesity prevention interventions in terms of target behaviours, delivery features and behav...
Introduction:
Behavioural interventions in early life appear to show some effect in reducing childhood overweight and obesity. However, uncertainty remains regarding their overall effectiveness, and whether effectiveness differs among key subgroups. These evidence gaps have prompted an increase in very early childhood obesity prevention trials wor...
Background: The present study aimed to test a model of perfectionism investigating parenting style, early maladaptive schemas and sensitivity to reinforcement theory.

This study aimed to investigate whether individuals with eating disorders (ED; N = 857) could be empirically classified into qualitatively distinct subgroups based on their emotion dysregulation profiles. A series of increasingly complex models (factor analysis; FA, latent class analysis; LCA, and factor mixture models; FMM) were evaluated to deter...
Background
The majority of Roux-en-Y gastric bypass (RYGB) patients are not sufficiently physically active post-surgery, yet little support from the Swedish healthcare system is offered. We investigated if a dissonance-based group intervention, aiming to increase health-related quality of life after surgery, had any effect on patients’ physical act...
Background
Parental self-efficacy (PSE) has been suggested as a key factor for enabling parents to support children in the development of healthy dietary and physical activity behaviors and to prevent childhood obesity. However, studies of intervention effects on PSE are lacking. The present study involved a secondary analysis of data on PSE collec...
Negowetti et al. (2021) have provided insightful perspectives on the public health implications of the labeling of “clean” dietary products in the United States through a scoping review, along with feasible strategies to counteract the risks of this trend. Although the European Union has already fairly strict regulations about declaration of ingred...
Background
A substantial proportion of patients receiving cognitive behavioural therapy (CBT) do not achieve remission, and drop-out is considerable. Motivational interviewing (MI) may influence non-response and drop-out. Previous research shows that MI as a pre-treatment to CBT produces moderate effects compared with CBT alone. Studies integrating...
Background
Self-harming behaviors in adolescents cause great suffering and can lead to considerable costs to the healthcare system. The aim of the current study was to investigate the cost of an integrated individual and family therapy (Intensive Contextual Treatment: ICT) and to compare the adolescent’s healthcare consumption 1 year before and 1 y...

The study aim was to evaluate the psychometric properties of the Swedish version of both scales. Two community samples were recruited through convenience sampling and were infor...
Background
Studies in Western cultures have shown that perfectionism is conceptualized by two-factor higher-order model including perfectionistic strivings and perfectionistic concerns. However, little is known about the construct of perfectionism in Eastern societies. Thus, we examined the two-factor higher-order model of perfectionism in Iranian...
Background: Self-harm is a major public healh concern and it is particularly prevalent among adolescents. The functions of self-harm are diverse, but can be devided into interpersonal and intrapersonal.

Purpose
Common mental disorders (CMDs) and musculoskeletal disorders are highly prevalent in the population and cause significant distress and disability, and high costs to society. The main objective of this systematic review and meta-analysis was to examine the outcome and comparative effectiveness of psychological interventions in reducing sickn...
Theories of maladaptive anxiety in children have suggested different developmental trajectories across age. Weems (2008) suggested that one subgroup of children demonstrates high and stable levels of broad anxiety, but shifting levels of dimension-specific symptoms in part due to related normative challenges. In a prospective longitudinal design, t...
Purpose: Despite positive health advantages of post-surgery physical activity (PA) for bariatric surgery patients, the majority is not sufficiently physically active. The aim was to explore women’s perceptions and experiences concerning PA five years after Roux-en-Y Gastric Bypass (RYGB) surgery.
