Efforts to reduce the global burden of common mental disorders have focused on scaling up evidence-based training programs for non-specialist providers to deliver brief psychological interventions. To evaluate these provider training programs, appropriate and scalable assessments of competency need to be developed alongside them. We followed a systematic approach for the cultural adaptation and translation into Hindi of a valid, English, multiple-choice applied knowledge measure to assess non-specialists' competence to deliver a brief psychological intervention for depression in rural India. We then explored the relationship between the performance of 30 non-specialist providers on the same written measure compared with a structured performance-based measure consisting of two role-plays. The results of the multiple-choice assessment had an overall mean score of 37.40 (SD = 11.31) compared to the mean scores of role-play A (the easier role-play) of 43.25 (SD = 14.50) and role-play B (the more difficult role-play) of 43.25 (SD = 13.00). Role-play performance-based measures and written applied knowledge measures represent different approaches with unique strengths and challenges to measuring competence. Scaling up training programs requires the development of scalable methods for competency assessment. Exploring the relationship between these two measures, our team found no apparent differences between the two modes of assessment. Continued comparison of these approaches is needed to determine the consistency of outcomes across the two formats and to link the scores on these measures with clinical performance as reflected by the quality of care and patient outcomes.Trial Registration: ClinicalTrials.gov Identifier: NCT04157816; 8th November 2019.

To map and examine the systematic review evidence base regarding the effects of cognitive-behavioral therapy (CBT) for eating disorders (EDs), especially against active interventions.This systematic review is an extension of an overview of CBT for all health conditions (CBT-O). We identified ED-related systematic reviews from the CBT-O database and performed updated searches of EMBASE, MEDLINE, and PsychInfo in April 2021 and September 2022.The 44 systematic reviews included (21 meta-analyses) were of varying quality. They focused on "high intensity" CBT, delivered face-to-face by qualified clinicians, in BN, BED and mixed, not specifically low-weight samples. ED-specific outcomes were studied most, with little consensus on their operationalization. The, often insufficient, reporting of sample characteristics did not allow assessment of the generalizability of findings. The meta-analytic syntheses show that high intensity one-to-one CBT produces better short-term effects than a mix of active controls especially on ED-specific measures for BED, BN, and transdiagnostic samples. There is little evidence favoring group CBT or low intensity CBT against other active interventions.While this study found evidence consistent with current ED treatment recommendations, it highlighted notable gaps that need to be addressed. There were insufficient data to allow generalizations regarding sex and gender, age, culture and comorbidity and to support CBT in AN samples. The evidence for group CBT and low intensity CBT against active controls is limited, as it is for the longer-term effects of CBT. Our findings identify areas for future innovation and research within CBT.This study provides a comprehensive mapping and quality assessment of the current large systematic review research base regarding the effects of cognitive behavioral therapy (CBT) for eating disorders (EDs), with a focus on comparisons to other active interventions. By transcending the more limited scope of individual systematic reviews, this overview highlights the gaps in the current evidence base, and thus provides guidance for future research and clinical innovation.Mapear y examinar la base de evidencia de la revisión sistemática con respecto a los efectos de la terapia cognitivo-conductual (TCC) para los trastornos de la conducta alimentaria (TCA), especialmente contra las intervenciones activas. MÉTODO: Esta revisión sistemática es una extensión de una visión general de la TCC para todas las afecciones de salud (TCC-O, Fordham et al., 2021a). Se identificaron revisiones sistemáticas relacionadas con los TCA a partir de la base de datos TCC-O y se realizaron búsquedas actualizadas en EMBASE, MEDLINE y PsychInfo en abril de 2021 y septiembre de 2022.Las 44 revisiones sistemáticas incluidas (21 metanálisis) fueron de calidad variable. Se centraron en la TCC de “alta intensidad”, administrada cara a cara por clínicos calificados, en BN, TpA y muestras mixtas, no específicamente de bajo peso. Los resultados específicos de los TCA fueron los más estudiados, con poco consenso sobre su operacionalización. El informe, a menudo insuficiente, de las características de la muestra no permitió evaluar la generalización de los hallazgos. Las síntesis metaanalíticas muestran que la TCC uno a uno de alta intensidad produce mejores efectos a corto plazo que una combinación de controles activos, especialmente en medidas específicas de TCA para TpA, BN y muestras transdiagnósticas. Hay poca evidencia a favor de la TCC grupal o la TCC de baja intensidad frente a otras intervenciones activas. DISCUSIÓN: Si bien este estudio encontró evidencia consistente con las recomendaciones actuales de tratamiento de los TCA, también destacó las brechas notables que deben abordarse. No hubo datos suficientes para permitir generalizaciones con respecto al sexo y el género, la edad, la cultura y la comorbilidad y para apoyar la TCC en las muestras de AN. La evidencia para la TCC grupal y la TCC de baja intensidad contra los controles activos es limitada, al igual que para los efectos a más largo plazo de la TCC. Nuestros hallazgos identifican áreas para la innovación y la investigación futuras dentro de la TCC.

Many individuals with lifetime histories of eating disorders (EDs) report exposure to interpersonal trauma and posttraumatic stress disorder (PTSD). However, this relationship is not well-understood, and there are no established, evidence-based therapies for the concurrent treatment of EDs and PTSD. This review focuses on studies of the mechanisms associating trauma exposure and/or PTSD with EDs. Possible mechanisms of the trauma-ED association identified from the literature include self-criticism, low self-worth, guilt, shame, depression, anxiety, emotion dysregulation, anger, and impulsivity/compulsivity. ED behaviors may be used as coping strategies to manage PTSD symptoms and negative affect. Avoidance of hyperarousal symptoms by engaging in binge eating, purging, and/or restriction may serve to maintain both the ED as well as the PTSD. Given the evidence of the bidirectional relationship between EDs and PTSD, we describe an integrated cognitive behavioral theory that may account for the persistence of comorbid PTSD and EDs. The integrated model is based on the theoretical models that underpin existing evidence-based treatments for PTSD and ED and incorporates many of the potential mechanisms highlighted to date. The primary aim of the model is to identify potential treatment targets as well as elucidate future directions for research.

Background The effectiveness of psychotherapeutic interventions for eating disorders (EDs) is widely studied in Europe, North America, and Australia/New Zealand. However, few controlled studies and no randomized controlled trials (RCTs) have been conducted in Japan despite the relatively high prevalence of EDs in the Japanese population. The aim of this study is to evaluate the effect of enhanced cognitive behavior therapy (CBT-E), an evidence-supported ED-focused form of cognitive behavior therapy (CBT), for the treatment of bulimia nervosa (BN) in Japan. Methods/design This multicenter RCT will compare CBT-E with treatment as usual (TAU), which is widely used in Japan. A group of 140 adult outpatients with a Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) diagnosis of BN, ≥18 years of age, a body mass index (BMI) > 17.5 and 2 will be randomly assigned to CBT-E or TAU. Participants will be stratified by intervention site and BN severity. CBT-E participants will receive 20 sessions of focused form CBT-E for 20 weeks. Those in the TAU group will receive routine treatment provided by specialists. Assessment will be performed in a blinded manner prior to the start of treatment, after 6 weeks of treatment, at the end of treatment (20 weeks), and at follow-up at 40 and 80 weeks after the start of treatment. The primary outcome is the remission of BN, defined by the absence, in the previous 4 weeks, of symptoms required to meet the DSM-5 criteria for a diagnosis of BN. Secondary outcomes include the levels of ED psychopathology and impairment due to the ED, anxiety, depression, family function, and satisfaction with treatment. Discussion This will be the first RCT conducted in Japan to compare CBT-E and TAU for the treatment of BN. If CBT-E is found to be more effective than TAU, then the evidence would support its wider use for patients with BN in Japan. Because it is possible to train therapists who do not possess extensive specialist experience, wider use is also likely to be practically feasible. In addition, demonstrating the effectiveness of CBT-E in Japan would demonstrate that it could be successfully extended to additional world cultures and regions.

It is well documented that sexual minority individuals are more likely to report disordered eating (DE) than those identifying as heterosexual. Although DE is prevalent in veterans, investigation of potential disparities in DE among sexual minority veterans is limited. This study examined rates of DE in post-9/11 United States (U.S.) veterans identifying as sexual minorities and explored their association with discrimination because of marginalized identities.A national sample of recently separated post-9/11 U.S. veterans were recruited. Women (N = 805; heterosexual [n = 656]; lesbian [n = 51]; bisexual [n = 98]) and men (N = 558; heterosexual [n = 540]; gay [n = 11]; bisexual [n = 7]) completed a survey assessing eating behaviors, mental health, and military experiences. Weighted correlational and regression analyses were conducted. Analyses in men were exploratory.DE was prevalent across gender and sexual orientation identity groups. Women identifying as bisexual and men identifying as gay reported higher rates of DE and consequent impairment compared to veterans who identified as heterosexual. There were no differences in DE between heterosexual and lesbian female veterans, but lesbian women reported lower DE-related impairment. Experiencing any discrimination in the military was positively related to DE.This study found evidence of disparities in DE among sexual minority U.S. military veterans. While the factors contributing to these differences, such as the role of discrimination, are not completely understood, DE is a health concern for sexual minority veterans and requires continued investigation.Sexual minority individuals experience disparities in disordered eating; yet, this has not been explored in military veterans. This study found that disordered eating is a significant health concerns for veteran women and men, especially among those identifying as sexual minorities. More research is needed to explore why these disparities exist, such as the role of minority stress, in order to address the unique healthcare needs of these veterans.

Healthcare use is elevated among individuals with eating disorders (EDs); however, most people with EDs do not receive ED-specific care, likely due to factors such as the cost and availability of treatment as well as stigma. U.S. military veterans historically have been understudied in ED research. We investigated healthcare use and barriers to care among recently separated veteran men and women.In this cross-sectional study, 1494 participants completed an online or paper survey assessing ED symptoms, healthcare use, and logistical and attitudinal barriers to care. We estimated logistic regression models to investigate the association of ED status with healthcare use variables and examined gender similarities and differences in barriers to care.Men and women with probable EDs reported low rates of ED treatment but greater healthcare use, during military service and since separating from service, compared to veterans without probable EDs (odds ratios = 1.57-7.05). Large proportions of participants reported that they did not know where to get help for EDs and that treatment is too costly. There were few gender differences in barriers to care (Cramer's V = 0.02-0.32).Veterans reported high healthcare use but low rates of ED treatment. Findings underscore the need to increase the reach and accessibility of ED treatment in potentially vulnerable groups.

Background Cognitive–behavioural therapy aims to increase quality of life by changing cognitive and behavioural factors that maintain problematic symptoms. A previous overview of cognitive–behavioural therapy systematic reviews suggested that cognitive–behavioural therapy was effective for many conditions. However, few of the included reviews synthesised randomised controlled trials. Objectives This project was undertaken to map the quality and gaps in the cognitive–behavioural therapy systematic review of randomised controlled trial evidence base. Panoramic meta-analyses were also conducted to identify any across-condition general effects of cognitive–behavioural therapy. Data sources The overview was designed with cognitive–behavioural therapy patients, clinicians and researchers. The Cochrane Library, MEDLINE, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Child Development & Adolescent Studies, Database of Abstracts of Reviews of Effects and OpenGrey databases were searched from 1992 to January 2019. Review methods Study inclusion criteria were as follows: (1) fulfil the Centre for Reviews and Dissemination criteria; (2) intervention reported as cognitive–behavioural therapy or including one cognitive and one behavioural element; (3) include a synthesis of cognitive–behavioural therapy trials; (4) include either health-related quality of life, depression, anxiety or pain outcome; and (5) available in English. Review quality was assessed with A MeaSurement Tool to Assess systematic Reviews (AMSTAR)-2. Reviews were quality assessed and data were extracted in duplicate by two independent researchers, and then mapped according to condition, population, context and quality. The effects from high-quality reviews were pooled within condition groups, using a random-effect panoramic meta-analysis. If the across-condition heterogeneity was I 2 Results A total of 494 reviews were mapped, representing 68% (27/40) of the categories of the International Classification of Diseases, Eleventh Revision, Mortality and Morbidity Statistics. Most reviews (71%, 351/494) were of lower quality. Research on older adults, using cognitive–behavioural therapy preventatively, ethnic minorities and people living outside Europe, North America or Australasia was limited. Out of 494 reviews, 71 were included in the primary panoramic meta-analyses. A modest effect was found in favour of cognitive–behavioural therapy for health-related quality of life (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval –0.05 to 0.50, I 2 = 32%), anxiety (standardised mean difference 0.30, 95% confidence interval 0.18 to 0.43, prediction interval –0.28 to 0.88, I 2 = 62%) and pain (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval –0.28 to 0.74, I 2 = 64%) outcomes. All condition, subgroup and sensitivity effect estimates remained consistent with the general effect. A statistically significant interaction effect was evident between the active and non-active comparator groups for the health-related quality-of-life outcome. A general effect for depression outcomes was not produced as a result of considerable heterogeneity across reviews and conditions. Limitations Data extraction and analysis were conducted at the review level, rather than returning to the individual trial data. This meant that the risk of bias of the individual trials could not be accounted for, but only the quality of the systematic reviews that synthesised them. Conclusion Owing to the consistency and homogeneity of the highest-quality evidence, it is proposed that cognitive–behavioural therapy can produce a modest general, across-condition benefit in health-related quality-of-life, anxiety and pain outcomes. Future work Future research should focus on how the modest effect sizes seen with cognitive–behavioural therapy can be increased, for example identifying alternative delivery formats to increase adherence and reduce dropout, and pursuing novel methods to assess intervention fidelity and quality.

Increased interest in disseminating and implementing psychological treatments has focused on the need for evidence-based training programs for providers, especially those without specialized training. To evaluate provider-training programs, validated outcome measures are necessary; however, the scalable measurement of training outcomes has been largely overlooked. Current methods of assessing providers' ability to deliver psychological treatments are generally time-consuming and costly, representing a major bottleneck in scaling up mental health care for commonly occurring disorders such as depression. The present study describes the development and initial validation of a scalable measure for assessing provider competence in delivering a brief behavioral activation treatment for depression, called the Healthy Activity Program, adapted for primary care settings. The measure focuses on testing knowledge about the treatment and applied knowledge regarding how to skillfully deliver the treatment, both essential features of competence. The measure was tested on a sample of 531 respondents with a variety of educational levels and professional backgrounds and found to meet the requirements of the Rasch model. Three versions of the measure each of equal difficulty were derived to allow repeat testing of training outcomes over time. A scalable measure of provider competence is an essential first step towards supporting the wider dissemination and implementation of brief psychological interventions for depression, especially in low-resource settings.

Objective: Understanding the mechanisms of action of psychological treatments is a key first step in refining and developing more effective treatments. The present study examined hypothesized mediators of change of enhanced cognitive behavior therapy (CBT‐E) and interpersonal psychotherapy for eating disorders (IPT‐ED).Method: A series of mediation studies were embedded in a randomized controlled trial (RCT) comparing 20 weeks of CBT‐E and IPT‐ED in a transdiagnostic, non‐underweight sample of patients with eating disorders (N = 130) consecutively referred to the service. Three hypothesized mediators of change in CBT‐E (regular eating, weighing frequency, and shape checking) and the key hypothesized mediator of IPT‐ED (interpersonal problem severity) were studied.Results: The data supported regular eating as being a mediator of the effect of CBT‐E on binge‐eating frequency. The findings were inconclusive regarding the role of the other putative mediators of the effects of CBT‐E; and were similarly inconclusive for interpersonal problem severity as a mediator of the effect of IPT‐ED.Discussion: This research highlights the potential benefits of embedding mediation studies within RCTs to better understand how treatments work. The findings supported the role of regular eating in reducing patients' binge‐eating frequency. Other key hypothesized mediators of CBT‐E and IPT‐ED were not supported, although the data were not inconsistent with them. Key methodological issues to address in future work include the need to capture both behavioral and cognitive processes of change in CBT‐E, and identifying key time points for change in IPT‐ED.

Background Training non-specialist health workers (NSHWs) at scale is a major barrier to increasing the coverage of depression care in India. This trial will test the effectiveness of two forms of digital training compared to conventional face-to-face training in changing the competence of NSHWs to deliver a brief evidence-based psychological treatment for depression. Methods This protocol is for a three-arm, parallel group randomized controlled trial comparing three ways of training NSHWs to deliver the Healthy Activity Program (HAP), a brief manualized psychotherapy for depression, in primary care. The arms are: digital training (DGT); digital training combined with individualized coaching support (DGT+); and conventional face-to-face training (F2F). The target sample comprises N = 336 government contracted NSHWs in Madhya Pradesh, India. The primary outcome is change of competence to deliver HAP; secondary outcomes include cost-effectiveness of the training programs, change in participants' mental health knowledge, attitudes and behavior, and satisfaction with the training. Assessors blind to participant allocation status will collect outcomes pre- (baseline) and post- (endpoint) training to ascertain differences in outcomes between arms. Training program costs will be collected to calculate incremental costs of achieving one additional unit on the competency measure in the digital compared to face-to-face training programs. Health worker motivation, job satisfaction, and burnout will be collected as exploratory outcome variables. Discussion This trial will determine whether digital training is an effective, cost-effective, and scalable approach for building workforce capacity to deliver a brief evidence-based psychological treatment for depression in primary care in a low-resource setting.

In the past few weeks, coronavirus disease 2019 (COVID-19) has dramatically expanded across the world. To limit the spread of COVID-19 and its negative consequences, many countries have applied strict social distancing rules. In this dramatic situation, people with eating disorders are at risk of their disorder becoming more severe or relapsing. The risk comes from multiple sources including fears of infection and the effects of social isolation, as well as the limited availability of adequate psychological and psychiatric treatments. A potential practical solution to address some of these problems is to deliver enhanced cognitive behaviour therapy (CBT-E), an evidence-based treatment for all eating disorders, remotely. In this guidance we address three main topics. First, we suggest that CBT-E is suitable for remote delivery and we consider the challenges and advantages of delivering it in this way. Second, we discuss new problems that patients with eating disorders may face in this period. We also highlight potential opportunities for adapting some aspects of CBT-E to address them. Finally, we provide guidelines about how to adapt the various stages, strategies and procedures of CBT-E for teletherapy use in the particular circumstances of COVID-19. Key learning aims (1) To appreciate that CBT-E is suitable for remote delivery, and to consider the main challenges and potential advantages of this way of working. (2) To identify and discuss the additional eating disorder-related problems that may arise as a result of COVID-19, as well as potential opportunities for adapting some aspects of CBT-E to address them. (3) To learn how to adapt CBT-E for remote delivery to address the consequences of COVID-19. Specifically, to consider adaptations to the assessment and preparation phase, the four stages of treatment and its use with underweight patients and adolescents.

Background Loneliness is a transdiagnostic clinical phenomenon that can significantly impact mental health and well-being across the lifespan. Objective The aim was to combine existing theory and evidence-based treatment approaches to propose a comprehensive transdiagnostic cognitive-behavioral analysis of the maintenance of chronic loneliness relevant across disorders, age groups, and populations. Method A distillation and matching model-framework approach was taken to identify interventions designed to reduce loneliness. Eligible studies were coded for the presence of practice elements. The findings were combined with an analysis of the broader literature on loneliness and psychopathology to derive a comprehensive cognitive-behavioral analysis of the maintenance of loneliness over time across populations. Results The search yielded 11 studies containing 14 practice elements with relative frequencies ranging from 7% to 64%. The identified practice elements target putative mechanisms such as negative interpersonal appraisals, anxiety, and social skills deficits. Counterproductive behavior and cognitive processes such as self-focused attention were identified as maintenance factors based on the broader literature. A modular transdiagnostic model with multiple pathways is proposed to be consistent with the existing theoretical and treatment literature. Conclusions Combining the distillation and matching model framework with existing theory from the literature is a novel approach for developing a model of factors that maintain loneliness over time. The model has varying treatment implications for different populations including children with autism spectrum disorders and bereaved older adults. Targeting transdiagnostic processes has the potential to transform interventions for loneliness across a range of formats and settings. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Objective To characterize loss-of-control eating following sleeve gastrectomy surgery by comparing relevant patient groups. Method Participants were 431 adults seeking treatment for eating/weight concerns categorized into one of four groups: 1) overweight/obesity (OW/OB), 2) binge-eating disorder (BED), 3) “Bariatric Binge-Eating Disorder” (Bar-BED) defined as meeting all criteria for DSM-5 binge-eating disorder, except for the requirement of an unusually large amount of food, following sleeve gastrectomy surgery, and 4) “Bariatric Loss-of-Control Eating” (Bar-LOC Only), defined as experiencing at least once weekly loss-of-control eating episodes during the past month without the other associated clinical features and distress that characterize Bar-BED, following sleeve gastrectomy surgery. Results The Bar-BED and BED groups reported comparable levels of overall eating-disorder and depressive symptoms, and these levels were significantly higher than those levels reported by the OW/OB and Bar-LOC Only groups. Adjusting for age, body mass index, and race did not change the overall pattern of findings. Conclusion “Bariatric Binge-Eating Disorder” shares clinical features of DSM-5 binge-eating disorder, regardless of the quantity of food consumed. Careful assessment of loss-of-control eating, associated behavioral features, and distress is warranted following surgery. More broadly, our findings highlight the importance of assessing loss-of-control eating across patient groups with obesity.

Background Clinical assessment of eating behaviors with patients who undergo bariatric surgery is challenging because of the complexity of symptom presentation postoperatively. The Eating Disorder Examination (EDE) is a widely-used semistructured clinical interview of eating-disorder psychopathology, yet no studies have examined the interrater reliability among postoperative bariatric surgery patients. Objectives The present study aimed to examine the interrater reliability of the EDE, and an alternative classification of size-specific thresholds of binge-eating episodes in a postoperative bariatric surgery sample. Setting University School of Medicine, United States. Methods Participants interviewed were a randomly selected subset (n = 20) from a consecutive series of adults seeking treatment for eating concerns after bariatric surgery. Audio-taped interviews were rated independently by 1 of 4 expert raters. Interrater reliability was assessed using intraclass correlation coefficients (ICC) and kappa statistic. Results ICCs for the original 4 EDE subscales were excellent, ranging from .88 to .98. ICCs for the alternative brief 3 subscales were also excellent, with a range of .78 to .97. ICCs for bariatric loss-of-control eating episodes were in the good to excellent range, with a range of .66 to .99. Kappa agreement for bariatric overeating episodes was moderate (.60). Conclusions These findings, based on 4 expert raters, suggest that complex eating-disorder psychopathology, as well as the newly proposed eating behavior with size thresholds relevant to bariatric patients, can be reliably assessed. To our knowledge, this is the first study to provide initial evaluation and support for the interrater reliability of the original EDE with additional modified eating categories developed for postbariatric surgery patients.

The majority of those who seek treatment for binge eating disorder also have accompanying obesity or overweight. The best available psychological treatments for binge eating disorder produce good and lasting outcomes with regard to control over eating but virtually no weight loss, yet control over eating and weight loss are both important and valued goals of those who seek treatment. We have devised a model of the processes maintaining both the binge eating and the overweight or obesity that occurs in many patients with binge eating disorder who seek treatment. The model draws on previous research findings to highlight and integrate the factors maintaining both the disordered eating and the accompanying overweight or obesity. We outline a new treatment based on the proposed model that explicitly addresses the twin goals of cessation of binge eating and weight loss in an integrated fashion. The proposed treatment incorporates and integrates elements from two previously tested evidence-based interventions, enhanced cognitive behavioural therapy for eating disorders shown to reduce binge eating and cognitive behaviour therapy of obesity, which produces weight loss. To meet a major challenge for the treatment of binge eating disorder (BED), we have proposed that an integrated treatment with the goals of addressing both binge eating and overweight or obesity is worth researching further. Should this treatment be successful, the goals of many patients who seek treatment for BED are more likely to be met. This brief report proposes a new approach to clinical practice to be researched further. The evidence on the basis of which the case is made is derived from Level 1: evidence obtained from at least one properly designed randomized controlled trial; systematic reviews and meta-analyses; and experimental studies.

BACKGROUND One of the major barriers to the dissemination and implementation of psychological treatments is the scarcity of suitably trained therapists. A highly scalable form of Web-centered therapist training, undertaken without external support, has recently been shown to have promise in promoting therapist competence. OBJECTIVE The aim of this study was to conduct an evaluation of the acceptability and effectiveness of a scalable independent form of Web-centered training in a multinational sample of therapists and investigate the characteristics of those most likely to benefit. METHODS A cohort of eligible therapists was recruited internationally and offered access to Web-centered training in enhanced cognitive behavioral therapy, a multicomponent, evidence-based, psychological treatment for any form of eating disorder. No external support was provided during training. Therapist competence was assessed using a validated competence measure before training and after 20 weeks. RESULTS A total of 806 therapists from 33 different countries expressed interest in the study, and 765 (94.9%) completed a pretraining assessment. The median number of training modules completed was 15 out of a possible 18 (interquartile range, IQR: 4-18), and 87.9% (531/604) reported that they treated at least one patient during training as recommended. Median pretraining competence score was 7 (IQR: 5-10, range: 0-19; N=765), and following training, it was 12 (IQR: 9-15, range: 0-20; N=577). The expected change in competence scores from pretraining to posttraining was 3.5 (95% CI 3.1-3.8; P CONCLUSIONS Independent Web-centered training can successfully train large numbers of therapists dispersed across a wide geographical area. This finding is of importance because the availability of a highly scalable method of training potentially increases the number of people who might receive effective psychological treatments.

Background One of the major barriers to the dissemination and implementation of psychological treatments is the scarcity of suitably trained therapists. The currently accepted method of training is not scalable. Recently, a scalable form of training, Web-centered training, has been shown to have promise. Objective The goal of our research was to conduct a randomized comparison of the relative effects of independent and supported Web-centered training on therapist competence and investigate the persistence of the effects. Methods Eligible therapists were recruited from across the United States and Canada. They were randomly assigned to 1 of 2 forms of training in enhanced cognitive behavior therapy (CBT-E), a multicomponent evidence-based psychological treatment for any form of eating disorder. Independent training was undertaken autonomously, while supported training was accompanied by support from a nonspecialist worker. Therapist competence was assessed using a validated competence measure before training, after 20 weeks of training, and 6 months after the completion of training. Results A total of 160 therapists expressed interest in the study, and 156 (97.5%) were randomized to the 2 forms of training (81 to supported training and 75 to independent training). Mixed effects analysis showed an increase in competence scores in both groups. There was no difference between the 2 forms of training, with mean difference for the supported versus independent group being –0.06 (95% Cl –1.29 to 1.16, P=.92). A total of 58 participants (58/114, 50.9%) scored above the competence threshold; three-quarters (43/58, 74%) had not met this threshold before training. There was no difference between the 2 groups in the odds of scoring over the competence threshold (odds ratio [OR] 1.02, 95% CI 0.52 to 1.99; P=.96). At follow-up, there was no significant difference between the 2 training groups (mean difference 0.19, 95% Cl –1.27 to 1.66, P=.80). Overall, change in competence score from end of training to follow-up was not significant (mean difference –0.70, 95% CI –1.52 to 0.11, P=.09). There was also no difference at follow-up between the training groups in the odds of scoring over the competence threshold (OR 0.95, 95% Cl 0.34 to 2.62; P=.92). Conclusions Web-centered training was equally effective whether undertaken independently or accompanied by support, and its effects were sustained. The independent form of Web-centered training is particularly attractive as it provides a means of training large numbers of geographically dispersed therapists at low cost, thereby overcoming several obstacles to the widespread dissemination of psychological treatments.

Current methods of classifying eating disorders are concerned with the distinctions between the various clinical presentations within the eating disorders. Anorexia nervosa, bulimia nervosa, and binge eating disorder are regarded as distinct clinical states and, as such, each requires its own form of treatment. In this chapter, we argue for an alternative transdiagnostic approach, which might better reflect clinical reality. The transdiagnostic treatment derived from this theory is described in outline together with its numerous extensions and variations. Evidence supporting both the theory and the treatment is presented, and future directions for research are identified.

Purpose: To determine if physiotherapist-led cognitive-behavioural (CB) interventions are effective for low back pain (LBP) and described sufficiently for replication. Method: Randomised controlled trials (RCTs) of patients with LBP treated by physiotherapists using a CB intervention were included. Outcomes of disability, pain, and quality of life were assessed using the GRADE approach. Intervention reporting was assessed using the Template for Intervention Description and Replication. Results: Of 1898 titles, 5 RCTs (n = 1390) were identified. Compared to education and/or exercise interventions, we found high-quality evidence that CB had a greater effect (SMD; 95% CI) on reducing disability (−0.19; −0.32, −0.07), pain (−0.21; −0.33, −0.09); and moderate-quality evidence of little difference in quality of life (−0.06; −0.18 to 0.07). Sufficient information was provided on dose, setting, and provider; but not content and procedural information. Studies tended to report the type of CB component used (e.g., challenging unhelpful thoughts) with little detail on how it was operationalised. Moreover, access to treatment manuals, patient materials and provider training was lacking. Conclusions: With additional training, physiotherapists can deliver effective CB interventions. However, without training or resources, successful translation and implementation remains unlikely. Researchers should improve reporting of procedural information, provide relevant materials, and offer accessible provider training. Implications for RehabilitationPrevious reviews have established that traditional biomedical-based treatments (e.g., acupuncture, manual therapy, massage, and specific exercise programmes) that focus only on physical symptoms do provide short-term benefits but the sustained effect is questionable. A cognitive-behavioural (CB) approach includes techniques to target both physical and psychosocial symptoms related to pain and provides patients with long-lasting skills to manage these symptoms on their own. This combined method has been used in a variety of settings delivered by different health care professionals and has been shown to produce long-term effects on patient outcomes. What has been unclear is if these programmes are effective when delivered by physiotherapists in routine physiotherapy settings. Our study synthesises the evidence for this context.We have confirmed with high-quality evidence that with additional training, physiotherapists can deliver CB interventions that are effective for patients with back pain. Physiotherapists who are considering enhancing their treatment for patients with low back pain should consider undertaking some additional training in how to incorporate CB techniques into their practice to optimise treatment benefits and help patients receive long-lasting treatment effects.Importantly, our results indicate that using a CB approach, including a variety of CB techniques that could be easily adopted in a physical therapy setting, provides greater benefits for patient outcomes compared to brief education, exercise or physical techniques (such as manual therapy) alone. This provides further support that a combined treatment approach is likely better than one based on physical techniques alone.Notably, we identified a significant barrier to adopting any of these CB interventions in practice. This is because no study provided a description of the intervention or accessible training materials that would allow for accurate replication. Without access to provider training and/or resources, we cannot expect this evidence to be implemented in practice with optimal effects. Thus, we would urge physiotherapists to directly contact authors of the studies for more information on how to incorporate their interventions into their settings.

Anorexia nervosa is difficult to treat and no treatment is supported by robust evidence. As it is uncommon, it has been recommended that new treatments should undergo extensive preliminary testing before being evaluated in randomized controlled trials. The aim of the present study was to establish the immediate and longer-term outcome following “enhanced” cognitive behaviour therapy (CBT-E). Ninety-nine adult patients with marked anorexia nervosa (body mass index ≤ 17.5) were recruited from consecutive referrals to clinics in the UK and Italy. Each was offered 40 sessions of CBT-E over 40 weeks with no concurrent treatment. Sixty-four percent of the patients were able to complete this outpatient treatment and in these patients there was a substantial increase in weight (7.47 kg, SD 4.93) and BMI (2.77, SD 1.81). Eating disorder features also improved markedly. Over the 60-week follow-up period there was little deterioration despite minimal additional treatment. These findings provide strong preliminary support for this use of CBT-E and justify its further evaluation in randomized controlled trials. As CBT-E has already been established as a treatment for bulimia nervosa and eating disorder not otherwise specified, the findings also confirm that CBT-E is transdiagnostic in its scope., Highlights ► CBT-E is designed to address eating disorder psychopathology. ► The findings show that CBT-E can be used with patients with marked anorexia nervosa. ► Two-thirds of the patients completed treatment. ► Among the completers there was a substantial, and well maintained, response. ► The findings confirm that CBT-E is transdiagnostic in its scope.

Large numbers of therapists worldwide wish to receive training in how to deliver psychological treatments. Current methods of training are poorly suited to this task as they are costly and require scarce expertise. New forms of training therefore need to be developed that are more cost-effective and scalable. Internet-based methods might fulfil these requirements whilst having the added advantage of being able to provide trainees with extensive exposure to the treatment as practised. New strategies and procedures for evaluating training outcome are also required. These need to be capable of assessing the therapist's knowledge of the treatment and its use, as well as the therapist's ability to apply this knowledge in clinical practice. Standardised role play-based techniques might be of value in this regard. © 2011 Elsevier Ltd.

It is remarkably difficult for people with obesity to maintain a new lower weight following weight loss. The aim of the present study was to examine the immediate and longer-term effects of a new cognitive behavioural treatment that was explicitly designed to minimise this post-treatment weight regain. One hundred and fifty female participants with obesity were randomized to the new treatment, behaviour therapy (the leading alternative psychological treatment) or guided self-help (a minimal intervention). Both of the main treatments resulted in an average weight loss of about ten percent of initial weight whereas weight loss was more modest with guided self-help. The participants were subsequently followed-up for three years post-treatment. The great majority regained almost all the weight that they had lost with the new treatment being no better than the behavioural treatment in preventing weight regain. These findings lend further support to the notion that obesity is resistant to psychological methods of treatment, if anything other than a short-term perspective is taken. It is suggested that it is ethically questionable to claim that psychological treatments for obesity “work” in the absence of data on their longer-term effects.

Background Many risk factors have been implicated in the development of anorexia nervosa. Little is known about their relative contributions, nor in most cases is it clear whether they are specific to anorexia nervosa or risk factors for all eating disorders or for psychiatric disorder in general. Methods We used a case-control design involving the comparison of 67 female subjects with a history of anorexia nervosa with 204 healthy control subjects, 102 subjects with other psychiatric disorders, and 102 subjects with bulimia nervosa. A broad range of risk factors was assessed by interview. Results The subjects with anorexia nervosa and the healthy controls differed in their exposure to most of the putative risk factors. There was no greater exposure to factors that increased the likelihood of dieting, once the influence of other classes of risk factors had been taken into account. Premorbid perfectionism and negative self-evaluation were especially common and more so than among the general psychiatric controls. Parental obesity and an early menarche, together with parental psychiatric disorder, distinguished those with bulimia nervosa from those with anorexia nervosa. Conclusions There appears to be a broad range of risk factors for anorexia nervosa and bulimia nervosa, some of which are shared with other psychiatric disorders. Factors that increase the likelihood of dieting seem to have more important influence as risk factors for bulimia nervosa than anorexia nervosa. Perfectionism and negative self-evaluation appear to be particularly common and characteristic antecedents of both eating disorders.

SummaryThe DSM–IV scheme for classifying eating disorders is a poor reflection of clinical reality. In adults it recognises two conditions, anorexia nervosa and bulimia nervosa, yet these states are merely two presentations among many. As a consequence, at least half the cases seen in clinical practice are relegated to the residual diagnosis ‘eating disorder not otherwise specified’. The changes proposed for DSM–5 will only partially succeed in correcting this shortcoming. With DSM–6 in mind, it is clear that comprehensive transdiagnostic samples need to be studied with data collected on their current state, course and response to treatment. Only with such data will it be possible to derive an empirically based classificatory scheme that is both rooted in clinical reality and of value to clinicians.

Interpersonal psychotherapy (IPT) is a leading evidence-based treatment for those eating disorders in which binge eating is a feature. This article begins with a consideration of the rationale for using IPT to treat patients with eating disorders. This is followed by a review of the evidence supporting its use and a brief description of treatment including an illustrative clinical case vignette. The article closes with a discussion of possible future directions for research on IPT for eating disorders. Copyright © 2012 John Wiley & Sons, Ltd. Key Practitioner Message IPT for eating disorders (IPT-ED) closely resembles IPT for depression and primarily focuses on current interpersonal problems. It is well suited for helping patients to address interpersonal difficulties which appear to be maintaining the eating disorder.

It is a consistent finding that, among obese patients, the weight lost as a result of the most widely available treatments for obesity is almost always regained. This relapse appears to be attributable to the individual's inability to persist with the behavioural strategies needed to maintain the new lower weight. Little research has investigated the psychological mechanisms that might account for this phenomenon. This study aimed to identify psychological factors that predict weight regain. Fifty-four women with obesity who had lost weight by attending community slimming clubs were interviewed immediately after losing 10% of their initial body weight, and then followed-up every 2 months for a period of 1 year by means of telephone interviews. The results identified two prospective predictors of weight regain: one cognitive factor (dichotomous thinking) and one historical variable (maximum lifetime weight). The finding that a specific cognitive style is a significant predictor of relapse has implications for the treatment of obesity.

In recent years there has been widespread acceptance that cognitive behavior therapy (CBT) is the treatment of choice for bulimia nervosa. The cognitive behavioral treatment of bulimia nervosa (CBT-BN) was first described in 1981. Over the past decades the theory and treatment have evolved in response to a variety of challenges. The treatment has been adapted to make it suitable for all forms of eating disorder—thereby making it “transdiagnostic” in its scope— and treatment procedures have been refined to improve outcome. The new version of the treatment, termed enhanced CBT (CBT-E) also addresses psychopathological processes “external” to the eating disorder, which, in certain subgroups of patients, interact with the disorder itself. In this paper we discuss how the development of this broader theory and treatment arose from focusing on those patients who did not respond well to earlier versions of the treatment.

SummaryBinge eating occurs across the entire range of eating disorders. It is required for a diagnosis of bulimia nervosa but it is also seen in some cases of anorexia nervosa and in many cases of eating disorder not otherwise specified (usually referred to as eating disorder NOS or atypical eating disorder). This article focuses on the management of those eating disorders in which binge eating is a prominent feature.

Hetherington has recently argued that psychology's concern with anecdotal evidence, introspective data and rare or one-off events renders the methodology and explanatory model of the natural sciences inappropriate and inadequate; and as such psychology needs to develop its own methods of inquiry. However, an examination of his arguments reveals that psychological data do not require explanation of a radically different kind from that employed in the natural sciences. Hetherington is correct in emphasizing that what is distinctive about the subject matter of psychology is its concern with intentional content; however, the conclusions he draws about the special nature of psychological explanation are unwarranted.

The EDE is a semistructured interview which has been developed as a measure of the specific psychopathology of anorexia nervosa and bulimia nervosa. To establish its discriminant validity it was administered to 100 patients with anorexia nervosa or bulimia nervosa and to 42 controls. The two groups differed significantly on all items. Five subscales were derived on rational grounds and evaluated on the two populations. The α coefficients for each subscale indicated a satisfactory degree of internal consistency. The EDE provides clinicians and research workers with a detailed and comprehensive profile of the psychopathological features of patients with eating disorders.

Cognitive behavioral therapy (CBT) is the leading evidence-based treatment for bulimia nervosa. A new "enhanced" version of the treatment appears to be more potent and has the added advantage of being suitable for all eating disorders, including anorexia nervosa and eating disorder not otherwise specified. This article reviews the evidence supporting CBT in the treatment of eating disorders and provides an account of the "transdiagnostic" theory that underpins the enhanced form of the treatment. It ends with an outline of the treatment's main strategies and procedures.

“Eating disorder NOS” is the most common eating disorder encountered in outpatient settings yet it has been neglected. The aim of this study was to describe the characteristics of eating disorder NOS, establish its severity, and determine whether its high relative prevalence might be due to the inclusion of cases closely resembling anorexia nervosa or bulimia nervosa. One hundred and seventy consecutive patients with an eating disorder were assessed using standardised instruments. Operational DSM-IV diagnoses were made and eating disorder NOS cases were compared with bulimia nervosa cases. Diagnostic criteria were then adjusted to determine the impact on the prevalence of eating disorder NOS. Cases of eating disorder NOS comprised 60.0% of the sample. These cases closely resembled the cases of bulimia nervosa in the nature, duration and severity of their psychopathology. Few could be reclassified as cases of anorexia nervosa or bulimia nervosa. The findings indicate that eating disorder NOS is common, severe and persistent. Most cases are “mixed” in character and not subthreshold forms of anorexia nervosa or bulimia nervosa. It is proposed that in DSM-V the clinical state (or states) currently embraced by the diagnosis eating disorder NOS be reclassified as one or more specific forms of eating disorder.

Consistent predictors, and more especially moderators, of response to psychological treatments for eating disorders have not been identified. The present exploratory study examined predictors and moderators of outcome in adult patients who took part in a randomised clinical trial comparing two leading treatments for these disorders, enhanced cognitive behavioural therapy (CBT-E) and interpersonal psychotherapy (IPT). Four potentially important findings emerged. Firstly, patients with a longer duration of disorder were less likely to benefit from either treatment. Second, across the two treatments the presence, at baseline, of higher levels of over-evaluation of the importance of shape predicted a less good treatment outcome. Third DSM-IV diagnosis did not predict treatment outcome. Fourth, with the exception of patients with baseline low self-esteem who achieved a better outcome with CBT-E, it was generally not possible to identify a subgroup of patients who would differentially benefit from one or other treatment., Highlights • Investigated predictors and moderators of outcome in CBT-E and IPT for eating disorders. • Those with longer duration of disorder less likely to benefit from either treatment. • In both treatments high levels of shape concern associated with less good outcome. • DSM-IV diagnosis did not predict treatment outcome. • Generally, not possible to identify those who differentially benefit from CBT-E or IPT.

Background: Clinical perfectionism is a risk and maintaining factor for anxiety disorders, depression and eating disorders. Aims: The aim was to examine the psychometric properties of the 12-item Clinical Perfectionism Questionnaire (CPQ). Method: The research involved two samples. Study 1 comprised a nonclinical sample (n = 206) recruited via the internet. Study 2 comprised individuals in treatment for an eating disorder (n = 129) and a community sample (n = 80). Results: Study 1 factor analysis results indicated a two-factor structure. The CPQ had strong correlations with measures of perfectionism and psychopathology, acceptable internal consistency, and discriminative and incremental validity. The results of Study 2 suggested the same two-factor structure, acceptable internal consistency, and construct validity, with the CPQ discriminating between the eating disorder and control groups. Readability was assessed as a US grade 4 reading level (student age range 9–10 years). Conclusions: The findings provide evidence for the reliability and validity of the CPQ in a clinical eating disorder and two separate community samples. Although further research is required the CPQ has promising evidence as a reliable and valid measure of clinical perfectionism.

Eating disorders may be viewed from a transdiagnostic perspective and there is evidence supporting a transdiagnostic form of cognitive behaviour therapy (CBT-E). The aim of the present study was to compare CBT-E with interpersonal psychotherapy (IPT), a leading alternative treatment for adults with an eating disorder. One hundred and thirty patients with any form of eating disorder (body mass index >17.5 to, Graphical abstract, Highlights • CBT-E had a substantial and sustained effect. • The effect was seen across the entire transdiagnostic sample. • The response almost exactly replicated that obtained in the original CBT-E trial. • The response to interpersonal psychotherapy (IPT) was slower and less pronounced.

OBJECTIVE: The aims of the study were to identify the characteristics of the dieters most at risk of subsequently developing an eating disorder and to evaluate the feasibility of using a brief questionnaire to identify such dieters in advance. METHOD: A general population cohort of 2,992 young women who were dieting was identified. On four occasions over the subsequent 2 years, this cohort was sent a questionnaire concerning eating habits and attitudes. Participants whose responses suggested that they had developed an eating disorder were interviewed to establish their true case status. The baseline questionnaires of those who did and did not subsequently develop an eating disorder were compared to identify features that predicted future case status. RESULTS: One hundred four of the dieters developed an eating disorder of clinical severity during the 2 years of follow-up. Their baseline questionnaire scores differed in many respects from those who had not developed an eating disorder. Items associated with developing an eating disorder were selected by using three different statistical methods. A simple case-predicting instrument based on one of five items scoring above an optimal cut point had a sensitivity of 71% and a specificity of 72% (overall efficiency of 72%). CONCLUSIONS: Dieters who will develop an eating disorder within the next 2 years have distinctive features. It is feasible to identify them in advance with reasonable efficiency with a brief questionnaire. This questionnaire could be incorporated into routine health assessments, thereby identifying those at high risk.
