Gioia AN, Ali S, Reilly EE. Clinical Experiences Using Cognitive-Behavioral Therapy for Eating Disorders. Behav Ther 2024; 55:872-884. [PMID: 38937056 PMCID: PMC11219095 DOI: 10.1016/j.beth.2024.01.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 12/22/2023] [Accepted: 01/09/2024] [Indexed: 06/29/2024]
Abstract
Data suggests that despite the availability of evidence-based psychological treatments for eating disorders (EDs), techniques from these therapies may be less frequently used within real-life clinical practice. The aim of this study was to provide the opportunity for clinicians to give feedback on their experiences treating EDs using cognitive-behavioral therapy (CBT) through reporting on use of CBT techniques and barriers to treatment implementation in naturalistic settings. Clinicians (N = 126) who self-identified as using CBT for EDs reported demographic information, frequency/usefulness of empirically supported treatment techniques, problems/limitations of CBT, and barriers faced while implementing CBT. The most frequently used technique reported by clinicians was psychoeducation, and the least frequently used technique was use of surveys to address mind reading. Patients' unwillingness to follow a meal plan/nutritional guide was rated as the most impactful barrier, alongside ED severity. Of the problems/limitations of CBT, too little guidance on treating co-occurring symptoms was rated as the most impactful. This study provided a mechanism for clinicians to share their experiences using CBT for EDs in real-world settings. Overall, results regarding frequency of use and usefulness of techniques indicate a high level of endorsement. Moreover, the most frequently endorsed barriers to/limitations of CBT related to lack of guidance on treating complex ED presentations. Future research should explore ways to treat cases that go beyond the prototypical ED case and explore ways to adapt CBT to meet the needs of naturalistic treatment settings.

Marney C, Reid M, Wright B. A mixed methods study of schema modes amongst people living with eating disorders. J Eat Disord 2024; 12:78. [PMID: 38867308 PMCID: PMC11167903 DOI: 10.1186/s40337-024-01031-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 05/24/2024] [Indexed: 06/14/2024] Open
Abstract
BACKGROUND Schema therapy is promising for people with eating disorders, especially those unresponsive to cognitive behavioural therapy. Complex underlying psychological constructs include dysfunctional schemas and maladaptive modes. This study aimed to explore people living with eating disorders' schema modes and their identification with and understanding of their high scoring modes. METHODS Sixteen women with enduring eating disorders without prior exposure to schema therapy completed the schema mode inventory for eating disorders short form (SMI-ED-SF), then participated in semi-structured interviews discussing their high scoring modes. Interviews were analysed by thematic analysis. RESULTS All participants scored above clinical concern on at least one maladaptive mode and many scored high on multiple modes, most commonly Demanding Mode, Vulnerable Child and Detached Self-Soother. Qualitatively, four themes emerged: 1) Adverse family environments related to (a) trauma and the vulnerable and angry child and (b) unrealistically high standards; 2) Mode effects on (a) everyday life and (b) disordered eating; 3) Modes are psychologically protective in (a) avoiding emotion by detachment and soothing, (b) people pleasing by compliance and surrender; 4) Help seeking including (a) barriers to recovery from an eating disorder, (b) dissatisfaction with interventions experienced to date, (c) schema therapy as a promising alternative. DISCUSSION Participants recognised and identified with their high scoring schema modes. After negative experiences with previous interventions, they considered schema therapy to be a promising alternative that could understand and work on their deeper psychological issues. This suggests that schema modes are a promising way of understanding and working with enduring eating disorders.

Abstract
Randomized controlled trials can be used to generate evidence on the efficacy and safety of new treatments in eating disorders research. Many of the trials previously conducted in this area have been deemed to be of low quality, in part due to a number of practical constraints. This article provides an overview of established and more innovative clinical trial designs, accompanied by pertinent examples, to highlight how design choices can enhance flexibility and improve efficiency of both resource allocation and participant involvement. Trial designs include individually randomized, cluster randomized, and designs with randomizations at multiple time points and/or addressing several research questions (master protocol studies). Design features include the use of adaptations and considerations for pragmatic or registry-based trials. The appropriate choice of trial design, together with rigorous trial conduct, reporting and analysis, can establish high-quality evidence to advance knowledge in the field. It is anticipated that this article will provide a broad and contemporary introduction to trial designs and will help researchers make informed trial design choices for improved testing of new interventions in eating disorders. PUBLIC SIGNIFICANCE: There is a paucity of high quality randomized controlled trials that have been conducted in eating disorders, highlighting the need to identify where efficiency gains in trial design may be possible to advance the eating disorder research field. We provide an overview of some key trial designs and features which may offer solutions to practical constraints and increase trial efficiency.

Abstract
OBJECTIVE We present the protocol of a feasibility randomised controlled trial (RCT) of intermittent theta burst stimulation (iTBS) for young people with anorexia nervosa (AN). Effective first-line psychological therapies exist for young people with AN, but little is known about how to treat those who do not respond. Non-invasive neuromodulation, such as iTBS, could address unmet treatment needs by targeting neurocircuitry associated with the development and/or maintenance of AN. DESIGN Sixty-six young people (aged 13-30 years) with persistent AN will be randomly allocated to receive 20 sessions of real or sham iTBS over the left dorsolateral prefrontal cortex in addition to their usual treatment. Outcomes will be measured at baseline, post-treatment (1-month post-randomisation) and 4-months post-randomisation (when unblinding will occur). Additional open follow-ups will be conducted at 12- and 24-months post-randomisation. The primary feasibility outcome is the proportion of participants retained in the study at 4-months. Secondary outcomes include AN symptomatology, other psychopathology, quality of life, service utilisation, neurocognitive processes, and neuroimaging measures. DISCUSSION Findings will inform the development of a future large-scale RCT. They will also provide exploratory data on treatment efficacy, and neural and neurocognitive predictors and correlates of treatment response to iTBS in AN.

Abstract
Anxiety and fear are key characteristics of eating disorders (EDs). Exposure therapy is a specific type of intervention aimed at reducing fear and anxiety and is efficacious in treating a variety of anxiety and related disorders. A growing body of research suggests that exposure therapy is also efficacious for the treatment of EDs. However, there is currently little research investigating mechanisms of change during exposure therapy for EDs. The current study (N = 143) expanded on an open series trial of imaginal exposure for EDs that found significant reductions in ED symptoms and core ED fears. In the current study we investigated change in state drive for thinness, body dissatisfaction, and anxiety as mechanisms underpinning change in ED symptoms and core ED fears during four sessions of online imaginal exposure treatment for EDs. We found that state body dissatisfaction, but not state drive for thinness or anxiety, was a mechanism of change for ED symptoms and some core ED fears. Our findings suggest that body dissatisfaction may be a mechanism driving change during exposure therapy for EDs. Optimizing exposure treatments to focus on body dissatisfaction may improve treatment outcomes for EDs.

Abstract
Eating disorders (EDs) are complex conditions with one of the highest mortality rates among psychiatric illnesses. While outpatient evidence-based treatments for EDs in adults exist, there is often utilisation of more intensive interventions as part of treatment. However, a comprehensive analysis of the impacts of intensive treatment (inpatient, residential and day program) on physical and psychosocial outcomes is lacking. Thus, the current systematic review and meta-analysis aimed to investigate the effectiveness of intensive treatments in adults with EDs for the outcomes of body mass index (BMI), disordered eating, depression, and quality of life, as well as a moderation analysis investigating a range of clinical characteristics. Overall, 62 studies were included in the meta-analysis. The results revealed that intensive treatment in adults yielded significant improvements in BMI (for underweight patients), disordered eating, depression, and quality of life. Treatment setting, length of stay and geographical region of the study all served as moderators for disordered eating and depression. Nevertheless, given the high heterogeneity in the meta- and moderation analyses, these results should be interpreted with caution. Future high-quality research is needed to determine the most beneficial elements of intensive treatment (compared to outpatient) in adults with EDs.

The usefulness of an intervention with a serious video game as a complementary approach to cognitive behavioural therapy in eating disorders: A pilot randomized clinical trial for impulsivity management. EUROPEAN EATING DISORDERS REVIEW 2023; 31:781-792.

Abstract
OBJECTIVE The aim of the present study was to test the usefulness of an add-on serious video game approach (i.e., Playmancer) to treatment as usual (TAU) on reducing impulsive behaviours and psychopathology in individuals diagnosed with an eating disorder (ED). METHOD Thirty-seven patients diagnosed with an ED according to the DSM-5 were included in the present randomized clinical trial (RCT; study record 35,405 in ClinicalTrials.gov) and were randomly assigned to either the TAU or TAU + Playmancer group. All participants completed a clinical interview. Impulsivity (UPPS-P self reported questionnaire and Stroop task) and general psychopathology (SCL-90-R) measures were assessed at: baseline, 4 weeks into treatment, at the end of TAU (after 16 weeks), and follow-up (2 years). In addition, patients in the experimental group underwent a total of nine sessions with Playmancer over the span of 3 weeks. RESULTS Patients in both treatment groups (TAU + Playmancer or TAU) improved on Stroop task performance and psychological distress. Additionally, patients in TAU-Playmancer improved on the impulsive trait domain of lack of perseverance. No statistical differences were found regarding treatment outcomes (i.e., treatment adherence and remission of eating symptomatology) when comparing the two treatment groups. CONCLUSION Our results suggest that the impulsivity associated with EDs should be addressed and could be modified, as some facets of trait impulsivity improved after Playmancer add-on treatment. Yet, there were no significant differences in treatment outcomes when comparing the two groups and further research needs to be conducted.

Abstract
PURPOSE Bulimia nervosa (BN) is characterized by recurrent binge-eating episodes and inappropriate compensatory behaviors. This study investigated alterations in resting-state surface-based neural activity in BN patients and explored correlations between brain activity and eating behavior. METHODS A total of 26 BN patients and 28 healthy controls were enrolled. Indirect measurement of cerebral cortical activity and functional connectivity (FC) analyses were performed in Surfstat. A principal component analysis (PCA) model was used to capture the commonalities within the behavioral questionnaires from the BN group. RESULTS Compared with the healthy control group, the BN group showed decreased surface-based two-dimensional regional homogeneity in the right superior parietal lobule (SPL). Additionally, the BN group showed decreased FC between the right SPL and the bilateral lingual gyrus and increased FC between the right SPL and the left caudate nucleus and right putamen. In the FC-behavior association analysis, the second principal component (PC2) was negatively correlated with FC between the right SPL and the left caudate nucleus. The third principal component (PC3) was negatively correlated with FC between the right SPL and the left lingual gyrus and positively correlated with FC between the right SPL and the right lingual gyrus. CONCLUSION We revealed that the right SPL undergoes reorganization with respect to specific brain regions at the whole-brain level in BN. In addition, our results suggest a correlation between brain reorganization and maladaptive eating behavior. These findings may provide useful information to better understand the neural mechanisms of BN. LEVEL OF EVIDENCE V, descriptive study.

Abstract
OBJECTIVE The high burden of eating disorders (EDs) and limited availability of treatment speaks of a need to explore new avenues for treatment delivery. To understand if new treatment avenues are helpful and acceptable to patients, we investigated the effectiveness of Physical Exercise and Dietary Therapy (PED-t) in participants with bulimia nervosa or binge-eating disorder, and acceptability when the PED-t was implemented in a Healthy Life Center in a municipal primary healthcare service. METHOD Exercise physiologists and one dietitian were trained in ED literacy and to run PED-t, before screening women for eligibility. Effectiveness (n = 16) of PED-t and participants' experiences (n = 8) were evaluated by a mixed methods study design. Results were analyzed by relevant statistics and reflexive thematic analysis. RESULTS Of 19 eligible participants, 16 completed treatment. At post-treatment, the Eating Disorder Examination Questionnaire global score, binge-eating frequency, and symptoms of depression were lower, and nine (56% of completers) were in remission. Participants' treatment experiences were classified into two overarching themes: "competence" and "emotional support." Participants reported high acceptance for PED-t, the local venue and group format, and felt that PED-t provided them with coping tools and increased mental strength. However, many also spoke of an unmet need to address emotional eating. DISCUSSION Findings point to a potential for making an effective ED therapy more accessible, and that participants find the local low-threshold delivery within a group-format helpful. With small adjustments, the PED-t could emerge as a promising first-line treatment for bulimic EDs. PUBLIC SIGNIFICANCE STATEMENT Limited access to treatment for EDs, patients' high barriers to help-seeking, and the high rates of limited efficacy from psychotherapy speak of a need to explore new therapies and avenues for delivery. In this study, we build on findings from a controlled ED treatment trial and replicate the beneficial effects and find a high patient acceptance of "physical exercise and diet therapy" implemented in a real, non-clinical setting.

Abstract
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.

Abstract
OBJECTIVE This study assessed the associations of binge eating, compensatory behaviors, and dietary restraint with the composition and diversity of the intestinal microbiota among participants with binge-eating disorder or bulimia nervosa. METHODS We analyzed data from 265 participants aged 18 to 45 years with current binge-eating disorder or bulimia nervosa enrolled in the Binge Eating Genetics Initiative study. We evaluated the associations of binge-eating frequency; presence/absence and frequency of vomiting, laxative use, and compulsive exercise; and dietary restraint with abundances of gut microbial genera, species, and diversity (Shannon diversity, Faith phylogenetic diversity, and Peilou's evenness) from 16S rRNA gene sequencing. General linear regression models adjusted for potential confounders, including age and current body mass index, were used to test associations; p values were corrected for the false discovery rate. RESULTS The normalized abundance of four genus- and species-level gut microbes and three diversity indices were lower among Binge Eating Genetics Initiative participants who reported any laxative use compared with those who reported no laxative use. Vomiting frequency was positively associated with the normalized abundance of the genus Escherichia-Shigella , a potential pathobiont, although the association was attenuated to nonsignificance after adjustment for age, body mass index, and binge-eating episodes. CONCLUSIONS Laxative use was highly and uniformly predictive of a reduced gut microbial diversity including potential commensals and pathobionts, and should be assessed and accounted for in all future studies of eating disorders and the gut microbiota. Future studies should collect data on specific medications-particularly laxatives-and dietary intake to obtain unbiased estimates of the effect of eating disorders on the gut microbiota and identify potential downstream clinical implications.Trial Registration:ClinicalTrials.gov identifier: NCT04162574 .

Co-producing principles to guide health research: an illustrative case study from an eating disorder research clinic. RESEARCH INVOLVEMENT AND ENGAGEMENT 2023; 9:84. [PMID: 37730642 PMCID: PMC10510247 DOI: 10.1186/s40900-023-00460-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 06/26/2023] [Indexed: 09/22/2023]
Abstract
BACKGROUND There is significant value in co-produced health research, however power-imbalances within research teams can pose a barrier to people with lived experience of an illness determining the direction of research in that area. This is especially true in eating disorder research, where the inclusion of co-production approaches lags other research areas. Appealing to principles or values can serve to ground collaborative working. Despite this, there has not been any prior attempt to co-produce principles to guide the work of a research group and serve as a basis for developing future projects. METHODS The aim of this piece of work was to co-produce a set of principles to guide the conduct of research within our lived experience led research clinic, and to offer an illustrative case for the value of this as a novel co-production methodology. A lived experience panel were recruited to our eating disorder research group. Through an iterative series of workshops with the members of our research clinic (composed of a lived experience panel, clinicians, and researchers) we developed a set of principles which we agreed were important in ensuring both the direction of our research, and the way in which we wanted to work together. RESULTS Six key principles were developed using this process. They were that research should aim to be: 1) real world-offering a clear and concrete benefit to people with eating disorders, 2) tailored-suitable for marginalised groups and people with atypical diagnoses, 3) hopeful-ensuring that hope for recovery was centred in treatment, 4) experiential-privileging the 'voice' of people with eating disorders, 5) broad-encompassing non-standard therapeutic treatments and 6) democratic-co-produced by people with lived experience of eating disorders. CONCLUSIONS We reflect on some of the positives as well as limitations of the process, highlighting the importance of adequate funding for longer-term co-production approaches to be taken, and issues around ensuring representation of minority groups. We hope that other health research groups will see the value in co-producing principles to guide research in their own fields, and will adapt, develop, and refine this novel methodology.

Pharmacotherapy compared to placebo for people with Bulimia Nervosa: A systematic review and meta-analysis. Psychiatry Res 2023; 327:115357.

Abstract
Bulimia Nervosa is a disorder with high rates of psychiatric and medical comorbidity and substantial societal costs. Cognitive Behavioural Therapy is considered the preferred treatment, but access can be problematic. Pharmacotherapy is more accessible but remains significantly underutilised. We aimed to assess the efficacy, tolerability, and safety of all available forms of pharmacotherapy for the treatment of bulimia nervosa. We conducted a comprehensive search of PubMed, EMBASE, CENTRAL, ClinicalTrials.gov, and reference lists of relevant articles up until April 2023. The primary outcomes were remission and binge frequency. 52 randomised controlled trials (RCTs) involving 3313 participants were included in the meta-analysis. Overall, no significant difference was observed between drugs and placebo in terms of remission; however, the available data were limited. Notably, drugs, particularly antidepressants, demonstrated a significant reduction in the frequency of binge episodes compared to placebo. Antidepressants were also found to be more effective than placebo in terms of treatment response and other clinically meaningful outcomes. An important limitation is that few RCTs were available for individual drugs. Our findings provide evidence supporting the increased utilisation of pharmacotherapy in clinical practice and underscore the need for further research involving larger populations and a broader range of outcomes.

Abstract
Given the mortality, chronicity, and treatment drop-out rates observed among individuals with eating disorders (EDs), innovative approaches are needed. Ayahuasca, a psychedelic plant medicine from the Amazon, is currently being investigated. This study expands on prior exploratory research by describing the perspectives of ayahuasca ceremony leaders regarding their conceptualizations of EDs and the potential therapeutic mechanisms of action of ayahuasca for individuals with EDs. Qualitative content analysis of interviews with 15 ayahuasca ceremony leaders produced two main categories, with relevant subcategories. The first category encompassed the leaders' theories of EDs from a shamanic perspective, including that EDs are symptomatic of an underlying concern, serve a function and affect health in multiple domains. The second category described leaders' perspectives on the potential mechanisms of action of ayahuasca for EDs, including that ayahuasca facilitates "energetic healing"; helps identify, process, and integrate the "root" of the ED; promotes holistic healing; and enhances and/or reorganizes relationships. From the perspectives of ceremony leaders and consistent with previous exploratory research, ceremonial ayahuasca use may offer a potentially useful, novel and complementary intervention for EDs.

Abstract
OBJECTIVE Eating disorders (EDs) are serious psychiatric disorders associated with substantial morbidity and mortality that are prevalent among university students. Because many students do not receive treatment due to lack of access on university campuses, mobile-health (mHealth) adaptations of evidence-based treatments represent an opportunity to increase treatment accessibility and engagement. The purpose of this study was to test the initial efficacy of Building Healthy Eating and Self-Esteem Together for University Students (BEST-U), which is a 10-week mHealth self-guided cognitive-behavioral therapy (CBT-gsh) app that is paired with a brief 25-30-min weekly telehealth coaching, for reducing ED psychopathology in university students. METHOD A non-concurrent multiple-baseline design (N = 8) was used to test the efficacy of BEST-U for reducing total ED psychopathology (primary outcome), ED-related behaviors and cognitions (secondary outcomes), and ED-related clinical impairment (secondary outcome). Data were examined using visual analysis and Tau-BC effect-size calculations. RESULTS BEST-U significantly reduced total ED psychopathology and binge eating, excessive exercise, and restriction (effect sizes ranged from -0.39 to -0.92). Although body dissatisfaction decreased, it was not significant. There were insufficient numbers of participants engaging in purging to evaluate purging outcomes. Clinical impairment significantly reduced from pre-to-post-treatment. DISCUSSION The current study provided initial evidence that BEST-U is a potentially efficacious treatment for reducing ED symptoms and ED-related clinical impairment. Although larger-scale randomized controlled trials are needed, BEST-U may represent an innovative, scalable tool that could reach greater numbers of underserved university students than traditional intervention-delivery models. PUBLIC SIGNIFICANCE Using a single-case experimental design, we found evidence for the initial efficacy of a mobile guided-self-help cognitive-behavioral therapy program for university students with non-low weight binge-spectrum eating disorders. Participants reported significant reductions in ED symptoms and impairment after completion of the 10-week program. Guided self-help programs show promise for filling an important need for treatment among university students with an ED.

Abstract
BACKGROUND Treatment for anorexia nervosa (AN) is typically delivered on a continuum of care, starting with outpatient treatment, and moving onto intensive outpatient, day or residential treatment and/or inpatient hospitalisation. However, minimal attention has been afforded to the lived experiences of persons undergoing inpatient treatment for AN. In particular, qualitative literature pertaining to the lived experiences of specialist inpatient or residential treatment of AN remains fragmented and incomplete. The aim of this review was to synthesise current literature exploring patients' lived experiences of residential and inpatient treatment for AN within eating disorder-specific treatment services. METHODS Five databases were searched and a qualitative thematic systematic review and meta-synthesis of 11 studies were conducted. RESULTS Eleven studies of 159 participants were included. Four meta-themes were constructed from the data: (1) a medical discourse-"I don't think it's individualised here"; (2) restrictive practice-living in a "bubble"; (3) myself, others and "a similar demon"; and (4) I am "not just another anorexic". The data also revealed two cross-cutting themes: (1) more than a single experience; and (2) meaning making and identity. CONCLUSIONS These findings highlight the complex and multifaceted nature of the inpatient treatment experience as well as the inherent conflicts in balancing the necessity of medical and psychological intervention with person-centred treatment approaches in the treatment of AN.

Abstract
PURPOSE Fear of weight gain may play a central role in maintaining eating disorders (EDs), but research on the role of fear of weight gain during cognitive behavioral therapy (CBT-E) for binge-spectrum EDs is sparse. We examined changes in fear of weight gain during CBT-E for binge-spectrum EDs. We investigated whether fear of weight gain predicted loss of control (LOC) eating or weight change. METHODS Participants (N = 63) were adults of any gender recruited as part of a larger trial. Participants received 12 sessions of CBT-E, completed diagnostic assessments at pre-, mid-, and post-treatment, and completed brief surveys before sessions. RESULTS Fear of weight gain decreased across treatment, moderated by diagnosis. Those with bulimia nervosa spectrum EDs (BN-spectrum), compared to binge eating disorder, reported higher fear of weight gain at baseline and experienced a larger decrease in fear across treatment. Those reporting higher fear of weight gain at a given session experienced more frequent LOC episodes the following week. Fear of weight gain was not associated with session-by-session changes in BMI. CONCLUSION CBT-E results in decreases in fear of weight gain, but levels remain high at post-treatment, especially for those with BN-spectrum EDs. Future interventions should consider targeting fear of weight gain as a maintaining factor for LOC episodes TRIAL REGISTRATION: NCT04076553. LEVEL OF EVIDENCE Level II controlled trial without randomization.

Abstract
BACKGROUND AND OBJECTIVES This study compared the effect of imagery rescripting focusing on self-compassion, imagery rescripting focusing on mastery, and a positive memory control condition on (1) emotional responses towards the memory (one day after), (2) changes in the believability of negative core beliefs, and dysfunctional eating behaviors (one week after) in individual at risk for developing an eating disorder. METHODS Female participants (N = 69) were allocated to one of three conditions: ImRs focusing on self-compassion (N = 24), ImRs focusing on self-mastery (N = 23), and positive memory control condition (N = 22). Participants in the ImRs conditions received a 20-min self-guided ImRs intervention, whereas participants in the control condition received a 20-min self-guided task focusing on an unrelated positive memory. RESULTS The experimental manipulation successfully induced the use of self-compassion and mastery strategies in the respective imagery rescripting condition. However, our data show that a single 20-min session of self-guided imagery rescripting focusing on compassion and/or mastery has no effect on the emotional response towards the aversive memory or in the change of core beliefs and eating behaviors at follow up. LIMITATIONS We discuss potential reasons for the null findings, including the use of a single imagery rescripting session, the sample size and the measurement of manipulation checks. CONCLUSION Future studies are needed to rule out methodological explanations for the null results. These findings may be of value for the development of future experimental lab paradigms which aim to evaluate the causal effects and working mechanisms of imagery rescripting.

Abstract
OBJECTIVE 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. METHOD 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. RESULTS 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. DISCUSSION 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. PUBLIC SIGNIFICANCE 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.

Abstract
PURPOSE OF REVIEW To review the literature pertaining to the assessment and treatment of avoidant/restrictive food intake disorder (ARFID) ten years following its introduction to DSM-5. RECENT FINDINGS Several structured clinical interviews for assessing ARFID have been developed, each with its own strengths and limitations. There is no clear leading self-report measure for tracking treatment progress and outcome in ARFID. Medical assessment is comprised of examining anthropometrics, vitamin deficiencies, and other comorbidities. To date, several studies have reported on cognitive behavioral therapy, family-based treatment, and other approaches to the treatment of ARFID. These treatments appear promising; however, they rely on data from clinical case series and very small randomized controlled trials. Several promising assessments and treatments for ARFID are in the early stages of research. Yet, controversies remain. These include (a) overlap with criteria for pediatric feeding disorder; (b) the optimal method for assessing nutrient deficiencies; (c) disciplines involved in treatment. Future research innovation is necessary to improve the psychometric properties of ARFID assessments and evaluate treatment efficacy with larger samples and randomized designs.

[PMID: 36612445 PMCID: PMC9819826 DOI: 10.3390/ijerph20010119] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 12/13/2022] [Accepted: 12/14/2022] [Indexed: 05/30/2023]
Abstract
Bulimia nervosa is an eating disorder characterised by marked impairment to one's physical health and social functioning, as well as high rates of chronicity and comorbidity. This literature review aims to summarise existing academic research related to the symptom profile of BN, the costs and burden imposed by the illness, barriers to the receipt of care, and the evidence base for available psychological treatments. As a consequence of well-documented difficulties in accessing evidence-based treatments for eating disorders, efforts have been made towards developing innovative, diverse channels to deliver treatment, with several of these attempting to harness the potential of digital platforms. In response to the increasing number of trials investigating the utility of online treatments, this paper provides a critical review of previous attempts to examine digital interventions in the treatment of eating disorders. The results of a focused literature review are presented, including a detailed synthesis of a knowledgeable selection of high-quality articles with the aim of providing an update on the current state of research in the field. The results of the review highlight the potential for online self-help treatments to produce moderately sized reductions in core behavioural and cognitive symptoms of eating disorders. However, concern is raised regarding the methodological limitations of previous research in the field, as well as the high rates of dropout and poor adherence reported across most studies. The review suggests directions for future research, including the need to replicate previous findings using rigorous study design and methodology, as well as further investigation regarding the utility of clinician support and interactive digital features as potential mechanisms for offsetting low rates of engagement with online treatments.

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

Abstract
A significant proportion of those with eating disorders (EDs) do not respond to first-line treatments. This systematic review was conducted to identify whether personality disorders (PDs)/traits predict or moderate ED treatment outcomes and whether these outcomes were differentially influenced by ED or PD diagnostic subtypes, or treatment approach. A comprehensive systematic literature search was conducted using the PRISMA guidelines. A total of seven randomised controlled trials (RCTs) plus four follow-up studies were reviewed investigating the impact of PD and PD traits on treatment outcomes for EDs. The majority indicated that PD had some impact on treatment outcomes. Outcome measures and time-point measurements varied across studies. Included studies suggested that bulimia nervosa treatment outcomes were not hindered by co-morbidity of borderline PD; however, psychiatric impairment remained high at post-treatment and follow-up. Cluster C PDs were found to negatively impact treatment outcomes for binge ED and attrition rates for anorexia nervosa. Included studies suggested that interventions that addressed aspects of personality pathology showed greater main effects for ED treatment outcomes. There is an urgent need for future RCTs on ED treatments to include routine measures of core personality features to allow their impacts to be more thoroughly examined and for psychotherapies to be tailored accordingly.

Abstract
BACKGROUND Currently, there is limited empirical validation of feminist-informed or individualised interventions for the treatment of eating disorders. The aim of this study was to examine the effectiveness of a feminist-informed, individually delivered counselling intervention for the treatment of eating disorders at a community-based eating disorder treatment service. METHODS Eighty individuals aged between 17 and 64 years presenting to an outpatient eating disorder service were examined in a case series design at baseline, session 10, session 20 and end of treatment (session 30). Changes in eating disorder symptomology, depression, anxiety, stress, and mental health recovery over the course of treatment were examined in linear mixed model analyses. RESULTS The treatment intervention was effective in reducing eating disorder symptomology and stress and improving mental health recovery after 10 sessions in a sample of 80 eating disorder participants engaged with the treatment service. Reductions in eating disorder symptomology and stress and improvements to mental health recovery were maintained at session 20 and session 30. CONCLUSIONS The findings of this study provide preliminary support for feminist-informed and individualised interventions for the treatment of eating disorders in community-based settings.

Abstract
Over the past 30 years, attentional bias for body shape and weight content has been implicated in the precipitation and maintenance of body dissatisfaction and eating disorders. Although the existence of this bias toward body stimuli is well-established in female populations, it is comparatively understudied in men. This review aimed to examine the nature of this visual attentional bias toward male bodies in male samples across a range of different attentional paradigms, including eye-tracking, dot-probe, and the visual search task. Results were heterogenous, finding some evidence that men with higher body dissatisfaction and eating disorder symptoms demonstrated an attentional bias toward desirable bodies of other men, and undesirable features of their own bodies. These results suggest that schematic cognitive models of body dissatisfaction and eating disorders body may also be applicable to men, however more research is needed.

Abstract
Anorexia nervosa (AN) patients and their family-members share alexithymia, anxiety, depression, and other psychological symptoms, in the context of altered attachment. These domains have been individually studied in the context of eating disorders; few attempts have been made to study their interaction, especially including family members. In this study, alexithymia, parental-bonding, and psychopathology were assessed in 32 Italian families consisting of an adolescent AN patient, a sibling, and their parents. We aimed to (a) describe a sample of Italian families with a child affected by AN, notably including siblings; (b) investigate interactions between assessed constructs in patients and their siblings; and (c) investigate possible intergenerational effects. Results showed high alexithymia and psychopathological symptoms in patients but not in siblings, although the latter reported high obsession-compulsion and paranoid ideation scores. Patients' and siblings' alexithymia correlated with psychopathology. Parents reported generally low alexithymia. Perceived parental bonding was found to be suboptimal in most participants, yet no clear relationship was found between specific parenting styles and other measured traits, nor did we find any other relevant intergenerational effect. Anorexia nervosa implies psychological difficulties for all family members. Siblings' psychopathological traits are especially concerning and currently understudied. Implications for future research and clinical interventions are discussed.

Abstract
OBJECTIVE The pursuit of thinness and fear of gaining weight have been found to play an important role in eating disorder symptomatology. While these dimensions have typically been considered conjointly, emerging evidence suggests they may be distinct dimensions. The aim of this study was to explore the subjective experiences of fear of fatness and drive for thinness in young women with body image concerns. METHOD Young women endorsing weight concerns (N = 29, mean age = 20.86, SD = 2.70 years) were interviewed and asked to describe an experience of fear of fat and drive for thinness, respectively. RESULTS Qualitative analysis was conducted and identified four themes: (1) precipitating events; (2) physiological, emotional, cognitive, and proprioceptive experiences; (3) coping strategies; and (4) sociocultural influences. While similarities emerged, the experiences of fear of fatness, and of drive for thinness also evidenced clear differences situating the former in the context of fear-based avoidance patterns, and the latter in approach-based reward models. DISCUSSION These findings provide additional support for the usefulness of considering fear of fat and drive for thinness as distinct constructs. Further research examining the contributions of each of these constructs to eating pathology is warranted.

Abstract
This study aimed to determine the associations between psychosis symptoms and eating disorders among a national sample of college and university students ages 18 to 26 years. Data from the 2020-2021 Healthy Minds Study (United States) were analyzed (N = 96,791). Multiple modified Poisson regression analyses were conducted to estimate the association between four self-reported lifetime psychosis symptoms and a positive eating disorder screen (measured using the SCOFF) and any self-reported lifetime eating disorder diagnosis, while adjusting for demographic and confounding variables. Participants who reported all four lifetime psychosis symptoms were more likely to screen positive for an eating disorder, while participants who reported three lifetime psychosis symptoms were more likely to report any lifetime eating disorder diagnosis. Those who reported a higher cumulative number of lifetime psychosis symptoms and reported any psychosis symptoms in the past 12 months were more likely to screen positive for an eating disorder and report any lifetime eating disorder diagnosis. Psychosis symptoms were associated with eating disorders among a national sample of college students. Health care professionals should be aware of the relationship between psychosis symptoms and eating disorders to ensure effective screening and early-intervention.

Abstract
BACKGROUND This trial examined the feasibility, acceptability, and effect sizes of clinical outcomes of an intervention that combines inhibitory control training (ICT) and implementation intentions (if-then planning) to target binge eating and eating disorder psychopathology. METHODS Seventy-eight adult participants with bulimia nervosa or binge eating disorder were randomly allocated to receive food-specific, or general, ICT and if-then planning for 4 weeks. RESULTS Recruitment and retention rates at 4 weeks (97.5% and 79.5%, respectively) met the pre-set cut-offs. The pre-set adherence to the intervention was met for the ICT sessions (84.6%), but not for if-then planning (53.4%). Binge eating frequency and eating disorder psychopathology decreased in both intervention groups at post-intervention (4 weeks) and follow-up (8 weeks), with moderate to large effect sizes. There was a tendency for greater reductions in binge eating frequency and eating disorders psychopathology (i.e. larger effect sizes) in the food-specific intervention group. Across both groups, ICT and if-then planning were associated with small-to-moderate reductions in high energy-dense food valuation (post-intervention), food approach (post-intervention and follow-up), anxiety (follow-up), and depression (follow-up). Participants indicated that both interventions were acceptable. CONCLUSIONS The study findings reveal that combined ICT and if-then planning is associated with reductions in binge eating frequency and eating disorder psychopathology and that the feasibility of ICT is promising, while improvements to if-then planning condition may be needed.

Abstract
PURPOSE Mirror exposure (ME) is embedded within cognitive behavioral treatment of body image concern (BIC), and existing literature demonstrates its potential value as a BIC intervention. The purpose of the study is to provide a meta-analytic review of ME effects on attitudinal and behavioral BIC. METHODS Twelve studies met inclusion criteria, yielding six between-group and 18 within-group comparisons. RESULTS Random effects models demonstrated a medium effect of ME versus control conditions, on attitudinal BIC, from pre- to immediate posttreatment, small effect at follow-up (1 to 4 weeks posttreatment), and large effect on behavioral BIC pre- to immediate posttreatment. However, small sample sizes yielded nonsignificant findings and significant heterogeneity. Exploratory moderator analyses-ME type, ME dosage (session frequency, duration), and diagnosis-demonstrated that, among single group pre-post designs, higher ME dosage may be instrumental to pre-posttreatment improvements. Consistent with this finding, individual studies with high dosages of ME demonstrated the largest effect sizes. Conclusion: Results may suggest a strong ME effect on BIC at high dosages (>120 minutes). The current review highlights gaps in ME literature and the need for future clinical trials assessing ME, using a priori, high-quality research designs that further the understanding of ME's mechanisms of change.

Abstract
Current treatments for binge eating disorder (BED) and bulimia nervosa (BN) only show moderate efficacy, warranting the need for novel interventions. Impairments in food-related inhibitory control contribute to BED/BN and could be targeted by food-specific inhibitory control training (ICT). The aim of this study was to establish the feasibility and acceptability of augmenting treatment for individuals with BN/BED with an ICT app (FoodT), which targets motor inhibition to food stimuli using a go/no-go paradigm. Eighty patients with BED/BN receiving psychological and/or pharmacological treatment were randomly allocated to a treatment-as-usual group (TAU; n = 40) or TAU augmented with the 5-min FoodT app daily (n = 40) for 4 weeks. This mixed-methods study assessed feasibility outcomes, effect sizes of clinical change, and acceptability using self-report measures. Pre-registered cut-offs for recruitment, retention, and adherence were met, with 100% of the targeted sample size (n = 80) recruited within 12 months, 85% of participants retained at 4 weeks, and 80% of the FoodT + TAU group completing ≤8 sessions. The reduction in binge eating did not differ between groups. However, moderate reductions in secondary outcomes (eating disorder psychopathology: SES = -0.57, 95% CI [-1.12, -0.03]; valuation of high energy-dense foods: SES = -0.61, 95% CI [-0.87, -0.05]) were found in the FoodT group compared to TAU. Furthermore, small greater reductions in food addiction (SES = -0.46, 95% CI [-1.14, 0.22]) and lack of premeditation (SES = -0.42, 95% CI [-0.77, -0.07]) were found in the FoodT group when compared to TAU. The focus groups revealed acceptability of FoodT. Participants discussed personal barriers (e.g. distractions) and suggested changes to the app (e.g. adding a meditation exercise). Augmenting treatment for BED/BN with a food-specific ICT app is feasible, acceptable, and may reduce clinical symptomatology with high reach and wide dissemination.

Abstract
OBJECTIVE One of the prevailing theories of eating disorders (ED) is the transdiagnostic cognitive behavioural theory of eating disorders, which suggests that certain ED symptoms, such as over-valuation of eating, shape, and weight, may be more central than others. In the present study, network analyses were used to evaluate these assumptions in a patient sample. METHODS Participants were 336 individuals receiving treatment at an expert center for ED in the Netherlands. Eating disorder symptoms were used to create transdiagnostic and diagnosis-specific networks and assess symptom centrality and density of the networks. RESULTS Networks for patients with bulimia nervosa and binge eating disorder confirmed that over-valuation of shape, weight, and eating is the most central symptom in the network. A transdiagnostic network of ED symptoms and separate networks for patients with anorexia nervosa and bulimia nervosa showed that strict dieting was an additional central ED symptom. An exploratory analysis revealed that, although eating disorder symptoms decreased, there were no differences in density of the eating disorder networks before and after treatment with cognitive behavioural therapy. DISCUSSION In conclusion, the current study confirmed that over-valuation of shape, weight, and eating is a central symptom across eating disorders, in agreement with the transdiagnostic cognitive behavioural model of eating disorders. Specifically targeting this symptom in treatment could lead to other symptoms improving as a result.

The legacy of hope summit: a consensus-based initiative and report on eating disorders in the U.S. and recommendations for the path forward. J Eat Disord 2021; 9:145. [PMID: 34736511 PMCID: PMC8567556 DOI: 10.1186/s40337-021-00501-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Accepted: 10/21/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Several unsuccessful attempts have been made to reach a cross-disciplinary consensus on issues fundamental to the field of eating disorders in the United States (U.S.). In January 2020, 25 prominent clinicians, academicians, researchers, persons with lived experience, and thought leaders in the U.S. eating disorders community gathered at the Legacy of Hope Summit to try again. This paper articulates the points on which they reached a consensus. It also: (1) outlines strategies for implementing those recommendations; (2) identifies likely obstacles to their implementation; and (3) charts a course for successfully navigating and overcoming those challenges. METHODS Iterative and consensual processes were employed throughout the Summit and the development of this manuscript. RESULTS The conclusion of the Summit culminated in several consensus points, including: (1) Eating disorder outcomes and prevention efforts can be improved by implementing creative health education initiatives that focus on societal perceptions, early detection, and timely, effective intervention; (2) Such initiatives should be geared toward parents/guardians, families, other caretakers, and frontline healthcare providers in order to maximize impact; (3) Those afflicted with eating disorders, their loved ones, and the eating disorders community as a whole would benefit from greater accessibility to affordable, quality care, as well as greater transparency and accountability on the part of in-hospital, residential, and outpatient health care providers with respect to their qualifications, methodologies, and standardized outcomes; (4) Those with lived experience with eating disorders, their loved ones, health care providers, and the eating disorders community as a whole, also would benefit from the establishment and maintenance of treatment program accreditation, professional credentialing, and treatment type and levels of care guidelines; and (5) The establishment and implementation of effective, empirically/evidence-based standards of care requires research across a diverse range of populations, adequate private and government funding, and the free exchange of ideas and information among all who share a commitment to understanding, treating, and, ultimately, markedly diminishing the negative impact of eating disorders. CONCLUSIONS Widespread uptake and implementation of these recommendations has the potential to unify and advance the eating disorders field and ultimately improve the lives of those affected. A cross-disciplinary group of eating disorder professionals, thought leaders, and persons with lived experience have come together and reached a consensus on issues that are fundamental to the battle against the life-threatening and life-altering illnesses that are eating spectrum disorders. Those issues include: (1) the need for early detection, intervention, prevention, and evidenced-based standards of care; (2) the critical need to make specialized care more accessible and affordable to all those in need; (3) the importance of developing uniform, evidenced-based standards of care; (4) the need for funding and conducting eating spectrum disorder research; and (5) the indispensability of advocacy, education, and legislation where these illnesses are concerned. During the consensus process, the authors also arrived at strategies for implementing their recommendations, identified likely obstacles to their implementation, and charted a course for successfully navigating and overcoming those challenges. Above all else, the authors demonstrated that consensus in the field of eating spectrum disorders is possible and achievable and, in doing so, lit a torch of hope that is certain to light the path forward for years to come.

Abstract
OBJECTIVE A rise of endogenous oxytocin (OT) is associated with anxiety and meal size reduction, and the effects of intranasal OT (INOT) have been examined in the management of food intake and craving. However, the discrepancy INOT effects in different disease populations are not entirely clear. RESEARCH DESIGN AND METHODS Updated systematic review and meta-analysis. By systematically searching the PubMed, Embase and Cochrane Library, we obtained 12 controlled trials. We performed meta-analyses to examine food intake, craving, anxiety or stress reduction on INOT administration, using standard mean difference (SMD) with a 95% confidence interval (CI) and a random-effects model. RESULTS This study examined 12 trials with 266 non-psychiatric and 157 psychiatric participants. The pooled results showed that single-dose INOT induced a significant lesser food intake in non-psychiatric subjects (SMD: -0.66 [95% CI: -1.18, -0.14]), but no effects was found in anorexia nervosa (AN) (SMD: 0.17 [95% CI: -0.32, 0.66]), bulimia nervosa (BN) and binge eating disorder (BED) (SMD: -0.41 [95% CI: -0.94, 0.11]), and schizophrenia (SMD: 0.04 [95% CI: -0.94, 1.02] subjects. Further analysis on leisure food also indicated an inhibition of consumption of chocolate biscuits in non-psychiatric subjects. Neither the non-psychiatric (SMD: -0.08 [95% CI: -0.50, 0.33]) nor the BN and BED (SMD: -0.08 [95% CI: -0.72, 0.88]) and schizophrenia subjects (SMD: -0.07 [95% CI: -1.05, 0.91]) demonstrated a difference in food craving or hunger compared with placebo. Anxiety or stress level was not influenced by INOT in any subgroup (non-psychiatric, SMD: 0.19 [95% CI: -0.22, 0.60]; AN, SMD: -0.01 [95% CI: -0.28, 0.88]; BN and BED: SMD: 0.00 [95% CI: -0.80, 0.80]). CONCLUSIONS Single-dose INOT significantly reduces food intake in nonpsychiatric subjects, and further studies are necessary to assess the long-term effects and safety in obese patients. Whether INOT could be a treatment option for patients with eating disorders remains to be investigated.

Abstract
Abstract
Background
This study compared the effect of imagery rescripting (ImRs) of early autobiographical memories to ImRs of intrusive images and a no task control condition on eating disorder (ED) related core beliefs and ED symptoms in individuals at risk of developing an eating disorder. We qualitatively explored the content of ImRs scripts.
Method
Participants (N = 66, 87.8% females) were allocated to one of three conditions: ImRs of autobiographical memories, ImRs of intrusive images, or a no task control condition. Participants in the ImRs conditions received a 9-min self-guided ImRs intervention in the lab and practiced ImRs daily for the next 6 days online. Participants in the no task control condition took a 9-min break and did not do any further tasks. All participants attended a follow-up testing 1 week after the lab session.
Results
Both ImRs manipulations resulted in greater reductions in negative core beliefs and ED symptoms compared to the no task control group. However, there were no differences among the two ImRs groups. The most widely used rescripting strategy was self-compassion, followed by unhealthy, ED-confirming strategies. No significant associations were found between the ImRs strategies and any of the outcome measures.
Conclusion
ImRs may be a promising intervention for individuals with disordered eating and both early memories as well as intrusive images may be useful targets.

Cost-Effectiveness Comparison of Delivery Modalities for a Dissonance-Based Eating Disorder Prevention Program over 4-Year Follow-Up. PREVENTION SCIENCE : THE OFFICIAL JOURNAL OF THE SOCIETY FOR PREVENTION RESEARCH 2021; 22:1086-1095. [PMID: 34152570 DOI: 10.1007/s11121-021-01264-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/09/2021] [Indexed: 12/24/2022]
Abstract
The cost-effectiveness of delivery methods for an eating disorder prevention program is reported. In an effectiveness trial (enrollment 2013-2015) comparing three formats (clinician-led, peer-led, and Internet-delivered) for delivering the Body Project eating disorder prevention program to college women versus an educational video control, the peer-led method was more effective than the three alternatives at preventing onset of eating disorders over 4-year follow-up. Eating disorder incidence was 19.3% for clinician-led groups, 8.1% for peer-led groups, 15.5% for Internet-based eBody Project participants, and 17.6% for educational video controls. Delivery costs per person are reported for the Body Project, including participant time, and the cost-effectiveness is calculated for peer-led groups versus the video control. Data analyses were conducted in 2019-2021. Delivery costs per person for the Body Project, including participant time, were approximately $96 for clinician-led groups, $80 for peer-led groups, and $22 for the eBody Project, compared with $9 for the educational video control. For each additional case of eating disorder onset that was prevented by the peer-led groups, compared with the video control, the cost was about $740. There were no differences in health care utilization across condition. Eating disorder prevention costs via the Body Project compare very favorably with the costs for treating an eating disorder, which previously have been estimated to range from approximately $20,300 for cognitive-behavioral therapy for bulimia nervosa to approximately $119,200 for adequate care treatment of anorexia nervosa. These analyses demonstrate the economic value of the Body Project for preventing eating disorders among college-age women when delivered in peer-facilitated groups.

Abstract
BACKGROUND AND OBJECTIVES No treatment for adult anorexia nervosa (AN) has shown sufficient effectiveness or superiority to other treatments. Overcontrol has been suggested as a viable mechanism to target in the treatment of patients with AN. Radically open dialectical behavior therapy (RO DBT) is developed for disorders related to maladaptive overcontrol. Our objective was to evaluate the outcome of RO DBT for AN in a clinical outpatient setting. METHODS Thirteen adult female patients with mild to moderate AN provided written consent and entered a multiple baseline single-case experimental design study. Median age at eating disorder (ED) onset was 15 years and the median duration of the ED was 10 years. Individual changes were assessed weekly during a baseline phase (A) of four to six weeks, and during the subsequent 40-week RO DBT phase (B). Additional assessments were conducted before and after treatment, and at a six-month follow-up. Primary outcome was ED psychopathology. Secondary outcomes were psychosocial impairment, quality of life, social connectedness, and adaptive control strategies. RESULTS Eight patients (62%) completed treatment. All completers were in full remission after treatment, with BMI ≥18.5 kg/m2 and ED psychopathology within one standard deviation of the community mean. Improvements occurred after introducing RO DBT, not during baseline. LIMITATIONS Participants were female with mild to moderate AN, limiting generalizability to severe AN or males. CONCLUSIONS The study provides preliminary support for using RO DBT in adult outpatients with AN and overcontrol. Further studies should replicate these findings.

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

Abstract
Posttraumatic stress disorder (PTSD) frequently co-occurs with eating disorders (ED) and is likely to be a powerful ED maintaining factor for a significant subgroup of individuals. The goal of PROJECT RECOVER is to develop and evaluate concurrent integrated treatment approaches for ED-PTSD to enable these individuals to recover from both their ED and PTSD. To date, we have trialed two approaches to concurrent/integrated treatment in PROJECT RECOVER: (1) concurrent delivery of Cognitive Processing Therapy (CPT) for PTSD to individuals receiving intensive ED treatment, and (2) delivery of a manualized individual cognitive-behavioral therapy (CBT) addressing both ED and PTSD (Integrated CBT for ED-PTSD) following a period of initial ED treatment. Interventions from both CBT for ED, and CPT for PTSD can be utilized and adapted to address the functional relationship between ED and PTSD, and promote full recovery from both disorders. Examples include integrating PTSD symptoms into the cognitive-behavioral individualized formulation of ED maintenance; integrating the ED into psychoeducation about PTSD maintenance; and identifying maladaptive beliefs that connect the ED to the trauma and/or PTSD. Emerging evidence suggests that CPT can be successfully integrated with CBT for ED.

Abstract
PURPOSE Provide qualitative descriptions of context and characteristics of binge eating in adults and adolescents to explore consistency in precipitating factors. METHOD Open-ended, qualitative interviews were administered to an adult sample (n = 24) and an adolescent sample (n = 20) to collect details about the context in which two binge episodes occurred. RESULTS Factors and context of the binge episodes were similar between adults and adolescents. In contrast, the two binge episodes described by each individual were not consistent. Binge episodes were not strongly affect-driven or food cue-driven. CONCLUSIONS Binge eating appears similar between adults and adolescents, which may have treatment implications. Similar treatment approaches may be used with both age groups and would benefit from covering a broad range of binge triggers rather than attempting to match individuals into an approach focused on particular triggers. LEVEL OF EVIDENCE Level III, case-control analytic study.

Diminished prefrontal cortex activation in patients with binge eating disorder associates with trait impulsivity and improves after impulsivity-focused treatment based on a randomized controlled IMPULS trial. NEUROIMAGE-CLINICAL 2021; 30:102679. [PMID: 34215149 PMCID: PMC8102655 DOI: 10.1016/j.nicl.2021.102679] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 04/14/2021] [Accepted: 04/15/2021] [Indexed: 01/18/2023]
Abstract
Persons with binge eating disorder show increased impulsivity. We investigated cognitive control to food cues using fNIRS. Compared to healthy controls, binge eaters show weaker activation of the prefrontal cortex. After behavioral therapy, binge eaters increase prefrontal cortex activation.
Background Behavioral and cognitive control are vital for healthy eating behavior. Patients with binge eating disorder (BED) suffer under recurrent binge eating episodes accompanied by subjective loss of control that results, among other factors, from increased impulsivity. Methods In the current study, we investigated the frontal network using functional near-infrared spectroscopy (fNIRS) during a food specific go/nogo task to assess response inhibition in 24 patients with BED (BMI range 22.6–59.7 kg/m2) compared to 12 healthy controls (HC) (BMI range 20.9–27 kg/m2). Patients with BED were invited to undergo fNIRS measurements before an impulsivity-focused cognitive behavioral group treatment, directly after this treatment and 3 months afterwards. As this was a planned subgroup analysis of the randomized controlled IMPULS trial, patients with BED were randomized either to the treatment group (n = 14) or to a control group (n = 10). The treatment group received 8 weekly sessions of the IMPULS treatment. Results We found a significant response inhibition effect (nogo minus go), in terms of an increased oxygenated hemoglobin response in the bilateral prefrontal cortex in both groups. The greatest response was observed when participants were instructed to go for healthy and withhold their response to unhealthy high caloric food cues. The healthy nogo condition failed to show a significant prefrontal inhibitory response, which was probably related to the task design, as the condition was considered more demanding. BED patients, especially those with higher trait impulsivity, showed a weaker activation of the prefrontal cortex during response inhibition, predominantly in the right hemisphere. Interestingly, three months after the treatment, patients of the treatment group increased their right prefrontal cortex activity during response inhibition. Likewise, increased prefrontal cortex activation correlated with decreased trait impulsivity after treatment. Conclusions Our results suggest that patients with BED have limited resources to activate the prefrontal cortex when asked to inhibit a reaction onto food-specific stimuli. However, this effect could be partly driven by differences in BMI between the HC and BED group. Cognitive-behavioral therapy targeting impulsive eating behavior may improve prefrontal cortex recruitment during response inhibition.

Abstract
Abstract
Background
Negative illness representations such as self-blame impede treatment-seeking behavior and therapy motivation in individuals with eating disorders (EDs). However, only one study so far has investigated how different explanatory models influence these beliefs in EDs. We aimed to expand these findings by introducing an explanatory model based on network theory (NT).
Methods
We presented three explanatory models to a diverse web-recruited sample (n = 290, 141 females, 149 males) with clinically elevated ED symptomatology. Participants either watched a video with a biological-genetic (BG), cognitive-behavioral (CB) or an NT explanatory model and were asked about illness representations before and after watching the video.
Results
The BG group showed significantly greater reductions in self-blame but a significant decrease in personal control and less optimistic expectation regarding timeline compared to the CB and NT groups. There were no group differences regarding the perception of the clinician, comprehensibility of the explanatory model and credibility of a CBT intervention.
Conclusions
Given the increasing popularity of biological-genetic explanatory models of EDs, it is important to note the disadvantages we found to be associated with these models. Our findings indicate that explanatory models emphasizing cognitive-behavioral (CB) principles and/or network theoretical (NT) underpinnings of EDs may serve to promote optimism and greater perceptions of personal agency in affected populations.
This trial's registration number is 316.

Metacognition and emotion regulation as treatment targets in binge eating disorder: a network analysis study. J Eat Disord 2021; 9:22.

Abstract
BACKGROUND This study aims to examine the underlying associations between eating, affective and metacognitive symptoms in patients with binge eating disorder (BED) through network analysis (NA) in order to identify key variables that may be considered the target for psychotherapeutic interventions. METHODS A total of 155 patients with BED completed measures of eating psychopathology, affective symptoms, emotion regulation and metacognition. A cross-sectional network was inferred by means of Gaussian Markov random field estimation using graphical LASSO and the extended Bayesian information criterion (EBIC-LASSO), and central symptoms of BED were identified by means of the strength centrality index. RESULTS Impaired self-monitoring metacognition and difficulties in impulse control emerged as the symptoms with the highest centrality. Conversely, eating and affective features were less central. The centrality stability coefficient of strength was above the recommended cut-off, thus indicating the stability of the network. CONCLUSIONS According to the present NA findings, impaired self-monitoring metacognition and difficulties in impulse control are the central nodes in the psychopathological network of BED whereas eating symptoms appear marginal. If further studies with larger samples replicate these results, metacognition and impulse control could represent new targets of psychotherapeutic interventions in the treatment of BED. In light of this, metacognitive interpersonal therapy could be a promising aid in clinical practice to develop an effective treatment for BED.

Abstract
PURPOSE OF REVIEW In current review, we evaluate the current literature examining the role of disgust in eating disorders (EDs), and provide a theoretical model designed to inform the study and treatment of disgust-based symptoms in EDs. RECENT FINDINGS Findings from this review suggest that aberrant disgust-conditioning processes represent promising but understudied mechanisms that may contribute to the risk and maintenance of core eating disorder (ED) psychopathology. In addition, preliminary evidence supports the use of interventions designed to target aversive disgust cues and disrupt maladaptive disgust-based conditioning that may maintain eating pathology. However, experimental studies designed to elucidate the role of disgust and aversive learning processes remain limited. Disgust is a promising risk and maintenance factor in EDs. Future systematic investigation is needed to examine disgust-based processes at a mechanistic level in order to better understand the links between disgust, avoidance behaviors, and EDs. Further investigation of the mechanistic role of disgust in EDs is warranted.

Abstract
Unhealthy cognitive–emotional relationships with exercise can hinder positive treatment outcomes when left unaddressed. However, clinicians lack validated tools to monitor this aspect of treatment. This study examined the 14-item Intuitive Exercise Scale with 165 patients in the United States (Mage = 26.48 years) who were receiving treatment for an eating disorder. The original factor structure was inadequate for the current sample, and exploratory factor analysis generated three factors—emotional exercise, body intuition, and exercise variety. The three-factor solution yielded strong internal consistency and partial support for the scale’s validity. Furthermore, patients scored lowest in body intuition, confirming low awareness of bodily cues common in patients with eating disorders. This study informs how clinicians may integrate and monitor patients’ cognitive–emotional relationship with exercise as part of holistic and intuitive eating disorder treatment approaches.

Abstract
OBJECTIVE Treating patients with eating disorders (EDs) is associated with an array of ethical concerns, including balancing patients' health and autonomy, access to care, and use of harm-reduction versus recovery-oriented treatment models. The primary aim of the current study is to gain a better understanding of ethical issues faced by ED practitioners by using a concept mapping, or Q-sort, approach. METHOD A total of 12 practitioners completed the brainstorming phase and generated statements regarding ethical issues they faced while treating patients with EDs. A subsequent 38 practitioners completed a sorting task, where they created and labeled piles, into which they grouped each statement. Of those 38 participants, 30 rated both the frequency with which they encountered each ethical issue and its impact on patient care. RESULTS A total of six clusters emerged: Insufficient Level of Care, Lack of Evidence-Based Practice, Insurance Barriers, Family Involvement, Patient Autonomy, and Limited Access to Expertise. Lack of Evidence-Based Practice, Insurance Barriers, and Insufficient Level of Care was the most frequent problem faced by ED practitioners, whereas Insurance Barriers and Patient Autonomy had the greatest impact. DISCUSSION Findings outline frequent and impactful areas of ethical concern that arise when treating patients diagnosed with EDs. Practitioners most commonly reported that patient- and insurance-driven factors limited patient access to appropriate care. Regulations supporting the provision of evidence-based care should be emphasized in public health policy and advocacy efforts, given their impact in limiting the delivery of adequate patient care.

Abstract
INTRODUCTION The Australia & New Zealand Academy for Eating Disorders (ANZAED) recently developed general principles and clinical practice standards recommended for mental health clinicians and dietitians providing treatment for people with eating disorders. Separate mental health practice and training standards were then devised as a foundation for strengthening the workforce and providing guidance to professional training programs and service providers on the minimal standards required for practice in the eating disorder field. RECOMMENDATIONS The present recommendations for mental health professionals providing eating disorder treatment describe the following practice and training standards: eating disorder treatment foundations (including co-ordination of services, establishing a positive therapeutic alliance, professional responsibility and knowledge of levels of care), assessment, diagnosis, intervention (including evidence-based intervention, managing psychiatric risk and managing co-morbid mental health problems), and monitoring and evaluation. CONCLUSIONS Further work is required to disseminate these standards to clinicians providing services across Australia to people with eating disorders, and to support adherence in the clinic room where they can translate to improved outcomes for clients. Pathways to supporting adherence include expert supervision of practice, incorporation in training and supervised practice in university settings, and support with checklists that can be used by consumers and referring professionals.
