The efficacy of psychological prevention, and health promotion interventions targeting psychological health, wellbeing or resilience among forced migrant children and youth: a systematic review and meta-analysis.

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 (secondary outcomes) in this population. The review protocol was registered with PROSPERO (CRD42022329978). Medline, PsycINFO, and Web of Science were searched. Inclusion criteria were: ≥ 10 participants, sample ≤ 18 years of age, no parental participation, explicated forced migrant populations, implementation in non-clinical context, and validated measures. Fifteen studies (N interventions = 18, N participants = 5741) were eligible. Two studies included outcomes related to wellbeing and quality of life. The remaining studies reported depression, PTSD, anxiety, internalizing and externalizing behaviours, and behavioural and emotional problems. There was only sufficient data to perform random-effects meta-analysis of depression scores. No significant effects were observed in comparison to control condition in randomized trials (n = 4994, k = 5) but a small significant positive trend was observed in within-group analyses (n = 537, k = 12). Cochrane's risk of bias tools and the GRADE certainty of evidence tool were applied. No studies achieved low risk of bias and certainty of evidence was very low. In sum, there remains a dearth of rigorous intervention studies investigating the effects of promotive and preventative psychological interventions on the wellbeing, resilience, and quality of life of forcibly displaced minors. However, the few eligible studies in this review indicate promise.

A Bibliometric Analysis of Scientific Publications on Eating Disorder Prevention in the Past Three Decades.

BACKGROUND: Eating disorders (EDs) present a growing concern due to their widespread occurrence and chronic course, the low access to evidence-based treatment, and the significant burden they place on the patients and society. This picture justifies intensive focus on the prevention of EDs. The current study provides the first bibliometric analysis of research on the prevention of EDs, focusing on trends and contributions, to prompt further prevention research. METHODS: We conducted a bibliometric analysis of publications on the prevention of EDs using the Web of Science database, from 1993 to 2023. Focusing on universal and selective prevention strategies, our study involved a rigorous selection process, narrowing down from 10,546 to 383 relevant papers through manual screening. The analysis utilized the "bibliometrix" R package (version 4.2.2) and Python (version 3.9.6) for data processing, with VOSviewer employed for mapping collaboration networks. RESULTS: Our analysis revealed a consistent annual growth rate of 10.85% in ED prevention research publications, with significant contributions from the "International Journal of Eating Disorders" and some notable authors. The United States emerged as the dominant contributor. The analysis also highlighted key trends, including a surge in publications between 2010 and 2017, and the role of major institutions in advancing research in this field. DISCUSSION: The increasing rate of publications on the prevention of EDs is encouraging. However, the actual number of studies on the prevention of EDs are limited, and the majority of this work is performed by a few research groups. Given the high concentration of publications within a few countries and research groups, increased funding, facilitation of prevention research on a wider scale, and engagement of more researchers and further collaboration are called for.

A pilot study of a virtually delivered dissonance-based eating disorder prevention program for young women with type 1 diabetes: within-subject changes over 6-month follow-up.

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 assessing within-subject changes in outcomes from pretest over 6-month follow-up. METHODS: Young women with T1D aged 16-35 years were invited to participate in Diabetes Body Project groups. A total of 35 participants were allocated to five Diabetes Body Project groups (six meetings over 6 weeks). Primary outcome measures included ED risk factors and symptoms, and secondary outcomes included three T1D-specific constructs previously found to be associated with ED pathology: glycemic control as measured by HbA1c level, diabetes distress, and illness perceptions. RESULTS: Within-subject reductions, with medium-to-large effect sizes, were observed for the primary (ED pathology, body dissatisfaction, thin-ideal internalization, and appearance ideals and pressures) and secondary outcomes (within-condition Cohen's ds ranged from .34 to 1.70). CONCLUSION: The virtual Diabetes Body Project appears to be a promising intervention worthy of more rigorous evaluation. A randomized controlled trial with at least a 1-year follow-up is warranted to determine its efficacy compared to a control condition.

Cognitive behavior therapy for adult eating disorders in routine clinical care: A systematic review and meta-analysis.

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 clinical settings. METHOD: Ovid MEDLINE, Embase OVID, and PsycINFO were systematically searched for articles published until June 2023. The outcome of CBT, methodological quality, risk of bias (RoB), and moderators of treatment outcome were examined and benchmarked by meta-analytically comparing with efficacy studies for ED. Fifty studies comprising 4299 participants who received CBT were included. RESULTS: Large within-group effect sizes (ES) were obtained for ED-psychopathology at post-treatment (1.12), and follow-up (1.22), on average 9.9 months post-treatment. Attrition rate was 25.5% and RoB was considerable in the majority of studies. The benchmarking analysis showed that effectiveness studies had very similar ESs as efficacy studies (1.20 at post-treatment and 1.28 at follow-up). CONCLUSION: CBT for ED is an effective treatment when delivered in routine clinical care, with ESs comparable to those found in efficacy studies. However, the evidence needs to be interpreted with caution due to the RoB in a high proportion of studies. PUBLIC SIGNIFICANCE: Eating disorders are common in the population and often lead to multiple negative consequences. CBT has been found effective for ED and is recommended in clinical guidelines. Since these recommendations are primarily based on university studies we wanted to investigate how CBT performs in routine clinical care. Our meta-analysis found that CBT worked as well in routine care as in university setting studies.

OBJETIVO: La terapia cognitivo-conductual (TCC) es un tratamiento recomendado para los trastornos de la conducta alimentaria (TCA) en adultos debido a su evidencia, basada principalmente en estudios de eficacia. Sin embargo, se sabe poco sobre cómo funciona la TCC en la atención clínica rutinaria. El objetivo de este meta-análisis es investigar cómo funciona la TCC para diversos TCA cuando se lleva a cabo en entornos clínicos habituales. MÉTODO: Se realizó una búsqueda sistemática en Ovid MEDLINE, Embase OVID y PsycINFO de artículos publicados hasta junio de 2023. Se examinaron el resultado de la TCC, la calidad metodológica, el riesgo de sesgo y los moderadores del resultado del tratamiento, y se compararon metaanalíticamente con estudios de eficacia para TCA. Se incluyeron cincuenta estudios que comprendían a 4299 participantes que recibieron TCC. RESULTADOS: Se obtuvieron tamaños del efecto (TE) grandes dentro del grupo para la patología de los TCA en el post-tratamiento (1.12) y en el seguimiento (1.22), en promedio 9.9 meses después del post-tratamiento. La tasa de abandono fue del 25.5% y el riesgo de sesgo fue considerable en la mayoría de los estudios. El análisis de comparación mostró que los estudios de efectividad tenían TE muy similares a los estudios de eficacia (1.20 en el post-tratamiento y 1.28 en el seguimiento). CONCLUSIÓN: La TCC para los TCA es un tratamiento efectivo cuando se administra en la atención clínica rutinaria, con TE comparables a los encontrados en estudios de eficacia. Sin embargo, la evidencia debe interpretarse con cautela debido al riesgo de sesgo en una alta proporción de los estudios.

Effectiveness of virtually delivered Body Project groups to prevent eating disorders in young women at risk: a protocol for a randomized controlled trial.

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 approaches for those at risk is therefore pivotal. The Body Project is the most effective ED prevention program for at-risk women according to several meta-analyses, but reach is limited since delivery, traditionally, has been in-person. Moreover, peer-led Body Project groups have been reported to produce stronger effects than clinician-led Body Project groups when delivered in-person. This has not yet been examined for virtually delivered Body Project groups. This study therefore seeks to investigate the effect of virtual Body Project groups delivered by peers versus clinicians on ED risk factors, ED symptoms, and prospective ED onset. METHODS: Young women with body image concerns aged 16-25 years (N = 441) will be included in the study and randomized to three conditions: (i) virtually delivered Body Project groups led by clinicians; (ii) virtually delivered Body Project groups led by peers; and (iii) psychoeducational control group. Participants will complete assessments at five timepoints over two years (pretest, posttest, 6-months, 1-year, and 2-years). DISCUSSION: Further research is needed to examine approaches to increase the potential for broad implementation of prevention of EDs. The virtual modality of the Body Project could markedly expand the reach for young women at risk. If findings confirm that peers can deliver virtual Body Project groups as effectively as clinicians, this will further enhance the implementation potential. TRIAL REGISTRATION: The present study has been registered on clinicaltrials.gov (NCT05993728).

This Special Issue of Nutrients on "Eating disorders and nutritional beliefs, trends or practices" contains ten empirical papers that cover various aspects of the topic [...].

The cost-effectiveness of a virtual intervention to prevent eating disorders in young women in Sweden.

OBJECTIVE: To determine the cost-effectiveness of a virtual version of the Body Project (vBP), a cognitive dissonance-based program, to prevent eating disorders (ED) among young women with a subjective sense of body dissatisfaction in the Swedish context. METHOD: A decision tree combined with a Markov model was developed to estimate the cost-effectiveness of the vBP in a clinical trial population of 149 young women (mean age 17 years) with body image concerns. Treatment effect was modeled using data from a trial investigating the effects of vBP compared to expressive writing (EW) and a do-nothing alternative. Population characteristics and intervention costs were sourced from the trial. Other parameters, including utilities, treatment costs for ED, and mortality were sourced from the literature. The model predicted the costs and quality-adjusted life years (QALYs) related to the prevention of incidence of ED in the modeled population until they reached 25 years of age. The study used both a cost-utility and return on investment (ROI) framework. RESULTS: In total, vBP yielded lower costs and larger QALYs than the alternatives. The ROI analysis denoted a return of US $152 for every USD invested in vBP over 8 years against the do-nothing alternative and US $105 against EW. DISCUSSION: vBP is likely to be cost-effective compared to both EW and a do-nothing alternative. The ROI from vBP is substantial and could be attractive information for decision makers for implementation of this intervention for young females at risk of developing ED. PUBLIC SIGNIFICANCE: This study estimates that the vBP is cost-effective for the prevention of eating disorders among young women in the Swedish setting, and thus is a good investment of public resources.

A randomized controlled trial of Safer Kids - A program for parents reported for child abuse: Short-term effects on further reports of child abuse and related risk factors.

BACKGROUND: Millions of children are victims of child abuse world-wide. Consequences include long-term health impacts and large societal costs. Parent training is promising to prevent abuse, but challenges with motivation and attrition must be overcome to reach parents in need. OBJECTIVE: To assess the effectiveness and acceptability of Safer Kids, a cognitive behavioral therapy-based parenting program delivered immediately after a report of child abuse. Safer Kids is used within the Child Welfare Services (CWS) in Sweden but has never been evaluated in an RCT. PARTICIPANTS AND SETTING: In total, 112 families with children 2-12 years referred to the Swedish CWS for physical or emotional child abuse participated. METHODS: Families were randomized to Safer Kids or intervention as usual (IAU). Data from parents, children and CWS were analyzed with multilevel and survival analyses. Primary outcomes were parent-rated child abuse potential and re-reports of abuse. Secondary outcomes were child abuse risk factors and treatment satisfaction. RESULTS: Data 4 and 7 months from baseline were available for 96 % of the families. All except one family (98 %) who started Safer Kids completed the program. Both groups improved from baseline to follow-ups on most effectiveness outcomes. The changes were not statistically different between groups. Parents and social workers were more satisfied with Safer Kids than IAU. CONCLUSIONS: Short manualized parenting programs can be a way to reach parents reported for child abuse with support. Safer Kids is a viable option to the CWS's standard interventions, as it was equally effective and slightly better accepted than IAU.

School-based self-harm prevention programs: A systematic review with implications for international implementation.

Both self-harm and suicidal behaviors have been targeted through school-based prevention programs, many of which have been developed in the United States. The aims of this systematic review were to assess effects of school-based prevention programs on suicide and self-harm and to evaluate whether they are fit to the exporting culture. The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Our inclusion criteria, structured according to population/problem, intervention, control/comparison, outome, were: children and youth up to 19 years of age, school-based programs at universal, selective or indicated levels compared with teaching as usual or with other programs, and outcomes of suicide or self-harm measured at least 10 weeks after intervention. Studies without a control group or using non-behavioral outcomes were excluded. A comprehensive and systematic literature search was conducted from the 1990s to March 2022. Risk for bias was assessed with checklists adapted from the Cochrane Risk of Bias (ROB) tool. A total of 1,801 abstracts were retrieved. Five studies fulfilled our inclusion criteria, but one had high risk for bias. Confidence in the evidence for effect was assessed with Grading of Recommendations Assessment, Development and Evaluation (GRADE). Studies included in this review were evaluated with respect to applicability in the context of international export. Only two school-based programs demonstrated efficacy in preventing suicidal behaviors. Although implementation of evidence-based interventions is a crucial next step, further replication with simultaneous attention to dissemination and implementation issues are called for. Funding and registration: conducted on assignment by the Swedish government. The protocol is available at the SBU website in Swedish.

Cognitive behavior therapy for adult post-traumatic stress disorder in routine clinical care: A systematic review and meta-analysis.

Although different cognitive behavioral therapies (CBT) have strong research support for treatment of adult post-traumatic stress disorder (PTSD) more knowledge is needed about the performance of CBT in routine clinical care. The present study is a systematic review and meta-analysis of CBT for PTSD in adults treated in routine clinical care. Ovid MEDLINE, Embase OVID, and PsycINFO were systematically searched for studies published until the end of May 2022. The effectiveness of CBT, methodological quality, and moderators of treatment outcome were examined, and benchmarked by meta-analytically comparing with efficacy studies for PTSD. Thirty-three studies, comprising 6482 participants, were included. The within-group effect sizes (ES) for PTSD-severity at post-treatment (1.75), and follow-up (1.70), on average 6 months post-treatment, were large. The effectiveness studies had very similar ESs as efficacy studies at post-treatment (1.75 vs. 1.72) and follow-up (1.70 vs. 2.02), based on the benchmarking analysis. As the heterogeneity was large, we can only cautiously consider CBT for PTSD an effective treatment when delivered in routine clinical care. The outcomes of effectiveness studies for PTSD seem to be comparable to the results obtained in efficacy studies. PROSPERO REGISTRATION ID: CRD42021228828.

Evaluating whether a peer-led dissonance-based eating disorder prevention program prevents onset of each eating disorder type.

BACKGROUND: This study tested whether the dissonance-based Body Project eating disorder prevention program reduced onset of subthreshold/threshold anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD) over long-term follow-up. METHODS: Data were combined from three prevention trials that targeted young women at high-risk for eating disorders (N = 1092; M age = 19.3). Participants were randomized to Body Project groups led by peer educators or expressive writing/educational controls and completed masked diagnostic interviews over 2- to 4-year follow-ups. Logistic regressions tested whether onset of each eating disorder over follow-up differed between Body Project and control participants. RESULTS: Peer-led Body Project groups produced a 46% reduction in onset of subthreshold/threshold BN and a 62% reduction in onset of PD relative to controls over follow-up. Rates of onset of subthreshold/threshold AN and BED did not significantly differ between peer-led Body Project participants and control participants. CONCLUSIONS: Results support the dissemination of the peer-led Body Project for reducing future onset of BN and PD. This study and recent research suggest that thin-ideal internalization, the risk factor for eating disorders targeted in the Body Project, may be more relevant for predicting onset of BN and PD compared to AN and BED. Findings support the development of a version of the Body Project aimed to reduce risk factors that have predicted future onset of all four types of eating disorders (e.g. overvaluation of weight/shape, fear of weight gain), which may more effectively prevent all eating disorder types.

A broad range: From simple and brief to intensive single-session interventions: Commentary on Schleider et al. (2023).

To push research and treatment in the field of eating disorders (EDs) forward, we need to not only systematically develop our current knowledge and skills through established procedures for research and clinical practice, but also make room for disruptive innovations and thinking out of the box. The paper by Schleider et al. (2023, International Journal of Eating Disorders) provides a thoughtful invitation to think differently by considering single-session interventions (SSI) for prevention and treatment of EDs. Beyond expanding our intervention tools, SSI may force us to think more mechanistically about the processes of change, and about the format and delivery of our interventions, both for EDs and from a transdiagnostic perspective. In this commentary, we reflect on the possible benefits and implications of SSI, and the necessity of mechanistically driven and rigorous empirical research for developing efficacious SSI.

Cognitive behavior therapy for adult depressive disorders in routine clinical care: A systematic review and meta-analysis.

BACKGROUND: Different cognitive behavioral therapies (CBT) have strong research support for treatment of adult depressive disorders (DD). Given the scarcity of knowledge about the performance of CBT in routine clinical care, a systematic review and meta-analysis of CBT for adults with DD treated in this context was conducted. METHODS: Published studies until the end of September 2022, were systematically searched in Ovid MEDLINE, Embase OVID, and PsycINFO. The effectiveness of CBT, methodological quality, and moderators of treatment outcome were examined, and benchmarked by meta-analytically comparing with efficacy studies for DD. RESULTS: Twenty-eight studies, comprising 3734 participants, were included. Large within-group effect sizes (ES) were obtained for DD-severity at post-treatment, and follow-up, on average 8 months post-treatment. Benchmarking analysis showed that effectiveness studies had very similar ESs as efficacy studies at post-treatment (1.51 vs. 1.71) and follow-up (1.71 vs. 1.85). Remission rates were also very similar; effectiveness studies 44 % and 46 %, efficacy studies 45 % and 46 %, at post-treatment and follow-up, respectively. LIMITATIONS: Only studies published in English-language peer-reviewed journals were included and the use of pre-post ES in the meta-analyses could contribute to biased outcomes. CONCLUSIONS: CBT for DD is an effective treatment when delivered in routine clinical care and the outcomes of effectiveness studies for DD are comparable to the effects obtained in efficacy studies.

Swedish parents' satisfaction and experience of facilitators and barriers with Family Check-up: A mixed methods study.

Family Check-up (FCU) was introduced in Sweden more than a decade ago. Little is known about what parents experience as FCU's key mechanisms leading to changes in parenting. The aim of this study was to investigate Swedish parents' satisfaction with FCU, and their experiences of facilitators and barriers for making changes in their parenting. A mixed methods approach was employed using a parent satisfaction questionnaire (n = 77) and focus groups (n = 15). General satisfaction with FCU was adequate, with an average rating of 4 on a five-point scale (range 3.1-4.6). The analysis of quantitative and qualitative data resulted in eight themes representing facilitators and four themes representing barriers, organized into three categories: (1) access and engagement; (2) therapeutic process; and (3) program components. Ease of access to FCU facilitated initial engagement. Individual tailoring and access to FCU during different phases of change facilitated sustained engagement and change. Therapeutic process facilitators were a meaningful, supportive relationship with the provider, psychological benefits for parents and benefits for the whole family. Program components that facilitated change in parenting were new learning of parenting strategies and use of helpful techniques such as videotaping and home practice. Negative experiences with service systems prior to starting FCU, parent psychological barriers, and parent-provider mismatch were described as potential barriers. Some parents desired other program formats that were not offered, and some felt that new learning was insufficient to improve child behavior. Understanding the parent perspective can contribute to successful future work with implementing FCU.

Development of competence in cognitive behavioural therapy and the role of metacognition among clinical psychology and psychotherapy students.

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 investigate to what extent psychology and psychotherapy students acquired competence in CBT following extensive training, and the role of metacognition. METHOD: CBT competence and metacognitive activity were assessed in 73 psychology and psychotherapy students before and after 1.5 years of CBT training, using role-plays with a standardised patient. RESULTS: Using linear mixed modelling, we found large improvements of CBT competence from pre- to post-assessment. At post-assessment, 72% performed above the competence threshold (36 points on the Cognitive Therapy Scale-Revised). Higher competence was correlated with lower accuracy in self-assessment, a measure of metacognitive ability. The more competent therapists tended to under-estimate their performance, while less competent therapists made more accurate self-assessments. Metacognitive activity did not predict CBT competence development. Participant characteristics (e.g. age, clinical experience) did not moderate competence development. CONCLUSIONS: Competence improved over time and most students performed over the threshold post-assessment. The more competent therapists tended to under-rate their competence. In contrast to what has been found in other learning domains, metacognitive ability was not associated with competence development in our study. Hence, metacognition and competence may be unrelated in CBT or perhaps other methods are required to measure metacognition.

Developing a Brief Parent Training Intervention to Prevent Anxiety in Offspring.

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 parents, the Supporting Anxious Parents Program (SAPP). The primary objective was to evaluate the acceptability of the SAPP. In addition, we also evaluated preliminary effects on child anxiety, parent risk factors, and quality of life, and feasibility of the study design. Excessive parental worry and anxiety and having a child not meeting criteria for an anxiety disorder (6-12 years old), served as inclusion criteria. Thirteen parents were randomly allocated to a group-based intervention, 14 to an individual Internet-based version of the intervention, and 13 to a waitlist control condition. The intervention was developed to target three risk factors involved in the parent-child transmission of anxiety; criticism/low warmth, overprotective behaviors, and modeling of anxiety. The results showed that parents were generally very satisfied with the intervention. We did not find any significant decreases in child anxiety in the intervention conditions. However, for the parents, we found preliminary support for reduced overprotective behaviors, reduced worry, and increased quality of life. The study design was found to be feasible. According to the results, a revision of the intervention is recommended before a full randomized controlled trial could be conducted.

Appearance and Performance-Enhancing Drugs and Supplements, Eating Disorders Symptoms, Drive for Muscularity, and Sexual Orientation in a Sample of Young Men.

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 regular use of supplements (at least once a week), including one individual using anabolic steroids (0.1%), while a lifetime use of APEDS was reported by 32.3%. The overlap between those using protein supplements and creatine was large (83.6%). Some symptoms of ED (e.g., dietary restraint, objective binge eating, self-induced vomiting, and excessive exercise) significantly predicted the use of APEDS. In addition, the use of APEDS was significantly predicted by the drive for muscularity. The prediction was stronger for the behavioral component of drive for muscularity (Exponential B = 8.50, B = 2.14, SE = 0.16, p < 0.001, Negelkerke R2 = 0.517) than for its attitudinal component (Exponential B = 1.52, B = 0.42, SE = 0.06, p < 0.001, Negelkerke R2 = 0.088). A significantly larger proportion of those identifying as heterosexual reported using APEDS (34.4%) compared to those identifying themselves as homosexual (25.0%), bisexual (19.2%) or other (23.7%). Overall, our results suggest that the use of APEDS might be more related to the drive for muscularity and sexual orientation than symptoms of ED.

Cognitive behavior therapy for obsessive-compulsive disorder in routine clinical care: A systematic review and meta-analysis.

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 systematically searched for studies published until July 2021. The effectiveness of CBT, methodological quality, and moderators of treatment outcome were examined, and benchmarked by meta-analytically comparing with efficacy studies for OCD. Twenty-nine studies (8 randomized controlled trials) were included, comprising 1669 participants. Very large within-group effect sizes (ES) were obtained for OCD-severity at post-treatment (2.12), and follow-up (2.30), on average 15 months post-treatment. Remission rates were 59.2% post-treatment and 57.0% at follow-up. Attrition rate was 15.2%. Risk of bias was considerable in the majority of studies. The benchmarking analysis showed that effectiveness studies had almost exactly the same ES as efficacy studies at post-treatment and somewhat higher at follow-up. Furthermore, effectiveness studies had significantly higher remission rates than efficacy studies, both at post- and follow-up assessment. CBT for OCD is an effective treatment when delivered in routine clinical care, with ES comparable to those found in efficacy studies. However, the evidence needs to be interpreted with caution because of the risk of bias in a high proportion of studies. PROSPERO REGISTRATION ID: CRD42021228828.

Internet-based cognitive behavior therapy for eating disorders - Development and feasibility evaluation.

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 aims of the present study were to (1) develop and evaluate the usability of an Internet-delivered guided self-help treatment based on Enhanced Cognitive Behavioral Therapy (ICBT-E) for patients with full or subthreshold bulimia nervosa (BN) or binge eating disorder (BED) with a user centered design process, and (2) to evaluate its feasibility and preliminary outcome in a clinical environment. Method: The study was undertaken in two stages. In Stage I, a user-centered design approach was applied with iterative phases of prototype development and evaluation. Participants were eight clinicians and 30 individuals with current or previous history of ED. In Stage II, 41 patients with full or subthreshold BN or BED were recruited to a single-group open trial to evaluate the feasibility and preliminary outcome of ICBT-E. Primary outcome variables were diagnostic status and self-rated ED symptoms. Results: The user-centered design process was instrumental in the development of the ICBT-E, by contributing to improvements of the program and to the content being adapted to the needs and preferences of end-users. The overall usability of the program was found to be good. ICBT-E targets key maintaining factors in ED by introducing healthy eating patterns and addressing over-evaluation of weight and shape. The results indicate that ICBT-E, delivered in a clinical setting, is a feasible and promising treatment for full or subthreshold BN or BED, with a high level of acceptability observed and treatment completion of 73.2 %. Participation in ICBT-E was associated with significant symptom reductions in core ED symptomology, functional impairment as well as depressive symptoms, and the results were maintained at the 3-month follow-up. Conclusions: ICBT-E was developed with end-users' preferences in mind, in accordance with the identified recommendations, and the program was perceived as usable by end-users. The study demonstrated the potential of ICBT-E, which marks a step forward in the effort to make powerful, empirically supported psychological interventions targeting ED more widely available and accessible.

Perception of the non-dominant hand as larger after non-judgmental focus on its details.

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-subject experiment (N = 82) was conducted. Subjects were mainly university students. They were asked to rate the size of their non-dominant hand and how much they liked it, and the size of an external object (a X-box controller) on a visual-analog scale before and after focusing on their details for 5 min, as well as the size of another object (a calculator) before and after a 5 min long distraction task. After completing the tasks, they were asked to respond to a brief questionnaire on body dissatisfaction. A s significant interaction between time and factors (non-dominant hand, X-box controller and calculator) emerged (F(2, 78) = 6.41, p = .003). Participants rated their hand as larger after focusing on its details compared to baseline, and this change was significantly larger than those reported for the X-box controller. No significant change in how they liked their hand was observed, and contrary to the pilot experiments, the perceived change in size of the hand was not related to body dissatisfaction. The significant change in reporting of the size of the hand after focusing on its details seems to be an interesting finding, worth further replications.
