Abstract
BACKGROUND Little is known about socioeconomic equity in access to healthcare among people with eating disorders in Australia. This study aims to measure the extent of inequity in eating disorder-related healthcare utilization, analyze trends, and explore the sources of inequalities using New South Wales (NSW) administrative linked health data for 2005 to 2020. METHODS Socioeconomic inequities were measured using concentration index approach, and decomposition analysis was conducted to explain the factors accounting for inequality. Healthcare utilization included: public inpatient admissions, private inpatient admissions, visits to public mental health outpatient clinics and emergency department visits, with three different measures (probability of visit, total and conditional number of visits) for each outcome. RESULTS Private hospital admissions due to eating disorders were concentrated among individuals from higher socioeconomic status (SES) from 2005 to 2020. There was no significant inequity in the probability of public hospital admissions for the same period. Public outpatient visits were utilized more by people from lower SES from 2008 to 2020. Emergency department visits were equitable, but more utilized by those from lower SES in 2020. CONCLUSIONS Public hospital and emergency department services were equitably used by people with eating disorders in NSW, but individuals from high SES were more likely to be admitted to private hospitals for eating disorder care. Use of public hospital outpatient services was higher for those from lower SES. These findings can assist policymakers in understanding the equity of the healthcare system and developing programs to improve fairness in eating disorder-related healthcare in NSW.

Protocol for a randomized clinical trial to confirm the effectiveness of online guided self-help family-based treatment for adolescent anorexia nervosa. Contemp Clin Trials 2024; 144:107618. [PMID: 38971303 PMCID: PMC11323053 DOI: 10.1016/j.cct.2024.107618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 06/17/2024] [Accepted: 07/03/2024] [Indexed: 07/08/2024]
Abstract
BACKGROUND The leading evidence-based treatment for anorexia nervosa (AN) in adolescents is Family-based Treatment (FBT). However, due to the intensive training requirements and lack of practitioners, it is often difficult for families to access FBT. Thus, innovations that improve access to care are needed. A pilot randomized study of a guided self-help version of Family-based Treatment (GSH-FBT) that utilized approximately 1/4 the amount of therapist time compared to FBT found that the approach was acceptable and appeared to achieve similar outcomes. The study protocol detailed in this manuscript compares the efficiency (clinician time) of GSH-FBT to Family-based Treatment via Videoconferencing (FBT-V) in a fully powered study in achieving clinical outcomes through a multi-site randomized clinical trial across the US and Ontario, Canada. METHODS This study will randomize the families of adolescents ages 12-18 (n = 200) who meet DSM-5 criteria for AN to receive either GSH-FBT or FBT-V. Participants will be randomized to 15 sixty-minute sessions of FBT-V or to 10 twenty-minute sessions of online GSH-FBT. Major assessments will be conducted by a masked assessor at baseline, within treatment, at the end of treatment (EOT), and 6 and 12 months after the end of treatment (EOT). The primary outcomes of this study are changes to body weight and eating disorder cognitions relative to clinician time used (relative efficiency of treatment modality). CONCLUSIONS The findings of this study may help increase access to care by providing a time efficient, affordable, more scalable intervention for adolescent AN compared to standard FBT.

Int J Eat Disord 2024; 57:1668-1679. [PMID: 38619359 DOI: 10.1002/eat.24213] [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: 02/09/2024] [Revised: 03/27/2024] [Accepted: 03/28/2024] [Indexed: 04/16/2024]
Abstract
OBJECTIVE Theoretical models highlight body image disturbances as central to the maintenance of eating disorders, with empirical evidence finding negative body image to be a robust predictor of treatment nonresponse, relapse and symptom persistence. Accessible, scalable, and inexpensive interventions that can effectively target negative body image across the eating disorders are needed. We developed an online single session intervention (SSI) for negative body image and evaluated its acceptability and efficacy in a randomized controlled trial in individuals with recurrent binge eating. METHOD Participants with recurrent binge eating were randomly assigned to the SSI (n = 99) or a waitlist (n = 101). Assessments were conducted at baseline, 4 week follow-up, and 8 week follow-up. RESULTS 81% of participants accessed the SSI, demonstrating reasonable uptake. However, issues with attrition were apparent; a 32% study dropout rate was observed at posttest, while a 58% dropout rate was observed at follow-up. 87% of participants who completed satisfaction measures would recommend the SSI. SSI participants experienced greater improvements in negative body image at both 4 (d = -0.65) and 8 week (d = -0.74) follow-up. Significant between-group effects were also observed on most other secondary symptom measures, though no differences were found for motivations and help-seeking beliefs and intentions. CONCLUSION Body image-focused self-guided SSIs for recurrent binge are largely accepted by those who are retained in the trial, but are associated with significant attrition. Although SSIs are not intended to replace standard treatment, they may help with short-term symptom management and could play an important role in eating disorder care. PUBLIC SIGNIFICANCE Single session interventions (SSI) are a potentially accessible, scalable, and cost-effective way to deliver evidence-based treatment content to people with eating disorders. This study shows that an online (SSI) designed to target body image among people with recurrent binge eating is accepted and produced short-term symptom relief.

Abstract
OBJECTIVE To identify patients presenting to an acute medical hospital with common signs and symptoms that occur in people with eating disorders (EDs), and determine by retrospective file audit if these are diagnosed cases of an ED. METHOD The investigators screened electronic medical records of people 16 years and older for common signs and symptoms of an ED such as hypokalemia, in patients presenting to an acute hospital in Sydney, Australia from 2018 to 2020. Cases where the clinical finding was unexplained had their file audited. Cases with a known ED diagnosis or coded with an ED were also retrieved to audit. RESULTS Investigators identified 192 definite ED cases with a total of 598 episodes of care from 2018 to 2020 presenting to the hospital. Eighty-three cases were identified as possible EDs due to unexplained clinical signs consistent with an ED, but were not confirmed cases due to lack of clinical history in the file. Only 19.1% of presentations were diagnostically coded with an ED in the electronic medical record. DISCUSSION Our study revealed a large number of definite ED cases presenting to an acute medical hospital via the emergency department, who were not recognized as having an ED. Greater awareness of clinical signs and symptoms of an ED, such as unexplained low body mass index and hypokalemia, is necessary among acute care clinicians. Correctly identifying EDs in those seeking somatic care should be a public health priority, to facilitate timely and equitable access to diagnostic assessment and evidence based treatment. PUBLIC SIGNIFICANCE People with eating disorders (EDs) present to acute care settings and have a relatively high utilization of generalist health services with nonspecific problems such as abdominal pain. An enhanced understanding of healthcare utilization by people with EDs, who may not disclose their symptoms, is crucial for improving access to treatment.

Abstract
BACKGROUND Remote research methods and interventions for mental health disorders have become increasingly important, particularly for conditions like eating disorders (EDs). Embodiment illusions, which induce feelings of ownership over another person?s body or body parts, offer valuable insights into the mechanisms underlying self-perception issues in EDs and potential interventions. However, existing research using these illusions has been limited to face-to-face settings. We illustrate a novel online protocol to induce the enfacement illusion (embodiment illusion principles applied to one's face) in an ED-based sample. METHODS Participants complete a 2-hr virtual session with a researcher. First, baseline trait/state ED psychopathology measures and a self-face recognition task occur. Second, participants experience two testing blocks of the enfacement illusion involving synchronously and asynchronously mimicking a pre-recorded actor's facial expressions. After each block, subjective and objective enfacement illusion measures occur alongside state ED psychopathology reassessment. DISCUSSION Successfully inducing enfacement illusions online could provide an affordable, accessible virtual approach to further elucidate the mechanistic role of self-perception disturbances across psychopathologies such as EDs. Moreover, this protocol may represent an innovative, remotely-delivered intervention strategy, as 'enfacement' over another face could update negative self-representations in a cost-effective, scalable manner.

Abstract
INTRODUCTION It is crucial to identify and evaluate feasible, proactive ways to reach teens with eating disorders (EDs) who may not otherwise have access to screening or treatment. This study aimed to explore the feasibility of recruiting teens with EDs to a digital intervention study via social media and a publicly available online ED screen, and to compare the characteristics of teens recruited by each approach in an exploratory fashion. METHOD Teens aged 14-17 years old who screened positive for a clinical/subclinical ED or at risk for an ED and who were not currently in ED treatment completed a baseline survey to assess current ED symptoms, mental health comorbidities, and barriers to treatment. Bivariate analyses were conducted to examine differences between participants recruited via social media and those recruited after completion of a widely available online EDs screen (i.e., National Eating Disorders Association [NEDA] screen). RESULTS Recruitment of teens with EDs using the two online approaches was found to be feasible, with 934 screens completed and a total of 134 teens enrolled over 6 months: 77% (n = 103) via social media 23% (n = 31) via the NEDA screen. Mean age of participants (N = 134) was 16 years old, with 49% (n = 66) identifying as non-White, and 70% (n = 94) identifying as a gender and/or sexual minority. Teens from NEDA reported higher ED psychopathology scores (medium effect size) and more frequent self-induced vomiting and driven exercise (small effect sizes). Teens from NEDA also endorsed more barriers to treatment, including not feeling ready for treatment and not knowing where to find a counselor or other resources (small effect sizes). DISCUSSION Online recruitment approaches in this study reached a large number of teens with an interest in a digital intervention to support ED recovery, demonstrating the feasibility of these outreach methods. Both approaches reached teens with similar demographic characteristics; however, teens recruited from NEDA reported higher ED symptom severity and barriers to treatment. Findings suggest that proactive assessment and intervention methods should be developed and tailored to meet the needs of each of these groups. PUBLIC SIGNIFICANCE This study examined the feasibility of recruiting teens with EDs to a digital intervention research study via social media and NEDA's online screen, and demonstrated differences in ED symptoms among participants by recruitment approach.

Abstract
PURPOSE OF REVIEW The present review describes the recent literature on treatment for binge-eating disorder (BED) in adults and youth, with a particular focus on research gaps, emerging treatments, and future research directions. RECENT FINDINGS Evidence supports the efficacy of several treatment modalities in adults, including self-help treatment, clinician-led psychotherapy, and pharmacotherapy; the largest effect sizes have been found for psychotherapies, most of which were cognitive-behavioral in orientation. Adapted psychotherapies for youth also show promise but lack a robust body of evidence. Predictors, moderators, and mediators of treatment outcome remain poorly understood; individuals with BED continue to experience significant barriers to treatment; and research is needed to address suboptimal treatment response. Recent work has highlighted the potential of adaptive interventions and investigation of novel mechanisms to address these gaps. Research on BED treatment continues to grow, though critical questions must be answered to improve treatment efficacy across the lifespan.

Abstract
OBJECTIVE Digital interventions show promise as an effective prevention or self-management option for eating disorders (EDs). However, it remains unclear how, for whom, and through what mechanisms they work in this population, as a synthesis of outcome predictors, moderators, and mediators is lacking. This systematic review synthesized empirical research investigating predictors, mediators, and moderators of response to digital interventions for EDs. METHOD Six databases were searched (PROSPERO CRD42022295565) for studies that assessed predictors, moderators, or mediators of response (i.e., uptake, drop-out, engagement, and symptom level change) to a digital prevention or treatment program for EDs. Variables were grouped into several overarching categories (demographic, symptom severity, psychological, etc.) and were synthesized qualitatively across samples without a formally diagnosed ED (typically prevention-focused) and samples with a formally diagnosed ED (typically treatment-focused). RESULTS Eighty-six studies were included. For studies recruiting samples without a formal diagnosis (n = 70 studies), most predictors explored were statistically unrelated to outcome, although participant age, baseline symptom severity, confidence to change, motivation, and program engagement showed preliminary evidence of prognostic potential. No robust moderators or mediators were identified. Few studies recruiting samples with a formal diagnosis emerged (n = 16), of which no reliable predictors, moderators, or mediators were identified. DISCUSSION It remains unclear how, for whom, and under what circumstances digital programs targeting EDs work. We offer several recommendations for future research with the aim of advancing understanding of client characteristics and intervention elements that signal success from this intervention modality. PUBLIC SIGNIFICANCE Digital interventions have shown potential as an effective, scalable, and accessible intervention option for EDs. However, responsiveness varies, so advancing understanding of predictors, mediators, and moderators of outcome to digital interventions for EDs is needed. Such knowledge is important for enabling safe and efficient treatment matching, and for informing future development of effective digital interventions.

Abstract
OBJECTIVE This study investigated how self-reliance and denial influence the relationship between help-seeking attitudes and behaviour. METHOD Australian university students (N = 406) completed an online survey and females with elevated eating disorder (ED) concerns and high impairment were included in the study (N = 137). Participants completed measures of help-seeking attitudes, perceived barriers, and actual help-seeking behaviour. Via moderated logistic regression, we examined self-reliance and denial as perceived barriers to help-seeking. RESULTS Of the total sample, over 33.7% of university students reported substantial ED concerns and impairment of whom 65.0% believed they needed help. While a majority reported that help-seeking would be useful (85.4%), only a minority of participants had sought professional help for their concerns (38.7%). Self-reliance and denial were frequently endorsed barriers and moderated the relationship between help-seeking attitudes and behaviours. CONCLUSION ED concerns are common among university students and perceived barriers play a moderating role between attitudes and help-seeking. Future prevention and early intervention programs should address students' denial, while the importance of reaching out for professional help (rather than relying on themselves) could be highlighted with peer support.

Abstract
BACKGROUND Prompt access to evidence-based treatment for children and young people with eating disorders is important for outcomes, yet the gap in service provision remains pervasive. Record levels of young people are waiting for eating disorder treatment and access to care is limited. Guided self-help interventions that are brief and require minimal clinician support have the potential to meet the unprecedented demand for treatment quickly and effectively. OBJECTIVE To examine the feasibility, acceptability and proof of concept of a novel, CBT guided self-help intervention for children and young people with threshold and subthreshold eating disorders. METHODS A single-arm, proof-of-concept pilot study of the CBT guided self-help intervention will be conducted. Children and young people (aged 11-19) with threshold and subthreshold eating disorders will receive a self-help intervention covering the core components of CBT, supported by 8 weekly guidance sessions delivered remotely. Clinical outcomes (eating-related psychopathology and associated impairment, changes in weight, depression, anxiety, and behavioural difficulties) will be assessed at baseline and post-intervention (12 weeks). Feasibility and acceptability of the intervention will be measured using various outcomes, including adherence to, and engagement with the intervention, rates of recruitment and retention, measure completion and treatment satisfaction. Qualitative data will also be collected for future intervention refinement. DISCUSSION If the intervention is shown to produce clinical benefits in this pilot study, a fully powered randomised pilot study will be warranted with the ultimate goal of increasing access to psychological treatment for children and young people threshold and subthreshold eating disorders. ADMINISTRATIVE INFORMATION This study protocol (S1 File) adheres to the guidelines outlined in the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) checklist for trial protocols [1, 2] which can be found in S1 Checklist. The numbers in parentheses in this protocol correspond to the item numbers in the SPIRIT checklist. The order of items has been modified to group similar items.

Abstract
PURPOSE Evidence shows that dialectical behavioural therapy (DBT) is efficacious for eating disorders (ED), yet few people have access to specialized treatments like DBT. Translating key DBT skills for delivery via a smartphone application may broaden the dissemination of evidence-based interventions. However, prior to developing a DBT-based app, it is crucial to gather information on target-user needs and preferences. Assessing overall acceptance and identifying predictors of acceptance, informed by the UTAUT framework, is also important. This process ensures not only a demand for such an app, but also that users receive content and features tailored to their needs. METHOD This study aimed to understand target-user preferences of DBT-based apps for EDs by assessing willingness to engage, overall acceptance levels, and preferred functionality/content delivery modes (n = 326 symptomatic participants). RESULTS Eighty-eight percent indicated they would be willing to use a DBT-based ED app if it were available. Acceptance levels of a DBT app were high (64%), which was uniquely predicted by performance expectancy (perceptions of how beneficial an intervention is) and facilitating conditions (expectations of technological infrastructure and support in interventions) in path analysis. Content perceived as important to contain were emotion regulation techniques, tailored intervention strategies, and psychoeducation. CONCLUSION Findings generate important information about target-user preferences of a DBT-based app for EDs, highlighting necessary design principles for apps of this kind. Level of evidence Level V, cross-sectional descriptive study.

Int J Eat Disord 2024; 57:376-387. [PMID: 38069451 DOI: 10.1002/eat.24105] [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: 07/17/2023] [Revised: 11/19/2023] [Accepted: 11/20/2023] [Indexed: 02/10/2024]
Abstract
OBJECTIVE This study examined the impact of the COVID-19 pandemic on healthcare engagement for anorexia nervosa (AN) and bulimia nervosa (BN) in a large, geographically diverse population. METHOD This repeated monthly, cross-sectional study queried Military Health System records of individuals aged 10-21 before and during the pandemic (February 2019-January 2022). ICD-10 codes identified encounters for AN and BN. Monthly rates of care were modeled as the number of unique individuals with an ICD-10-identified eating disorder-related encounter per month divided by the enrolled population. Poisson regression analysis evaluated rates of care stratified by eating disorder, clinical setting, and sex. RESULTS In a population of 1.76 million adolescents and young adults, 1629 individuals with AN or BN received care during the pre-pandemic period; 3256 received care during the pandemic. The monthly rate of care for females with AN during the pandemic increased in inpatient settings (adjusted relative risk [aRR]: 1.31 [1.16-1.49]) and outpatient settings (aRR: 1.42 [1.37-1.47]); monthly care rates in males with AN increased in the outpatient setting (aRR: 1.46 [1.28-1.67]). Females with BN had increased engagement in outpatient settings (aRR: 1.09 [1.03-1.16]); BN care for males showed no significant monthly changes during the pandemic period in either healthcare setting. DISCUSSION With increased rates of AN and BN disorder-related care during the pandemic, screening for eating disorder symptomatology may allow for timely diagnosis and intervention in periods of heightened stress. Pandemic-related increases in healthcare engagement may strain limited resources, emphasizing a need to expand accessibility of clinical expertise. PUBLIC SIGNIFICANCE This study indicates that monthly rates of healthcare engagement during the COVID-19 pandemic for AN and BN varied based on clinical setting and sex in an adolescent and young adult population. The increased number of individuals seeking eating disorder-related care, especially outpatient care, attributed to heightened stressors necessitates accessible professionals with eating disorder clinical expertise.

Improvements in Adolescents' Disordered Eating Behaviors in a Collaborative Care Digital Mental Health Intervention: Retrospective Observational Study. JMIR Form Res 2024; 8:e54253. [PMID: 38294855 PMCID: PMC10867747 DOI: 10.2196/54253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 12/14/2023] [Accepted: 12/28/2023] [Indexed: 02/01/2024] Open
Abstract
BACKGROUND Young people today are exhibiting increasing rates of disordered eating behaviors, as well as eating disorders (EDs), alongside other mental and behavioral problems such as anxiety and depression. However, limited access to mental health care means that EDs, disordered eating behaviors, and comorbid mental health problems are often underdiagnosed and undertreated. Digital mental health interventions (DMHIs) offer accessible and scalable alternatives to traditional treatment modalities, but their effectiveness has not been well established among adolescents with EDs and disordered eating behaviors. OBJECTIVE This study uses data from a collaborative care pediatric DMHI to determine whether participation in a DMHI is associated with a reduction in adolescents' disordered eating behaviors. METHODS Adolescent members in care with Bend Health Inc completed the SCOFF questionnaire at baseline (before the start of care) and approximately every month during care to assess disordered eating behaviors. They also completed assessments of mental health symptoms at baseline. Member characteristics, mental health symptoms, and disordered eating behaviors of adolescents with elevated SCOFF scores at baseline (before the start of care) were compared to those of adolescents with nonelevated SCOFF scores at baseline. Members participated in web-based coaching or therapy sessions throughout the duration of mental health care. RESULTS Compared to adolescents with nonelevated SCOFF scores (n=520), adolescents with elevated SCOFF scores (n=169) were predominantly female and exhibited higher rates of elevated anxiety and depressive symptoms. SCOFF scores decreased over time in care with the DMHI for 61.4% (n=70) of adolescents with elevated SCOFF scores, and each additional month of participation was associated with greater improvements in disordered eating behaviors (F1,233=72.82; P<.001). CONCLUSIONS Our findings offer promising preliminary evidence that participation in mental health care with a collaborative care DMHI may be beneficial in the reduction of disordered eating symptoms in adolescents, including those who are experiencing comorbid anxiety and depressive symptoms.

Abstract
OBJECTIVES Eating disorders (EDs) have a worldwide prevalence of 7.8%, with towering mortality rates and high healthcare costs. The current recommended treatment for EDs principally works by directly targeting ED thoughts and behaviours, but recovery rates are low. A multifaceted link between difficulties with emotions and EDs is now widely established, and newer third-wave therapies that aim to address these underlying emotion difficulties are promising. The current study piloted an online emotion self-help intervention which was co-developed with clinicians and people with lived experienced of EDs. The intervention aimed to specifically address difficulties with emotion identification and regulation, as well as unhelpful beliefs about emotions, which are believed to give rise to and maintain ED thoughts and behaviours. METHOD We recruited 39 people with self-reported EDs to test this intervention over a one-week period. Our participants were asked to complete a series of questionnaires measuring emotion processes and psychopathology on Day 1 (T1) before being given access to the intervention. Participants were then asked to practice the newly acquired skills for seven days, before taking the same questionnaires on Day 9 (T2). We also asked participants to qualitatively report on their experience of the intervention. RESULTS We found significant improvements in ED psychopathology (ED-15), depression (PHQ-9), and anxiety (GAD-7) pre- to post-intervention, with medium to large effect sizes. All our emotion variables namely alexithymia (TAS-20), difficulties regulating emotions (DERS-SF), and unhelpful beliefs about emotions (EBQ) also showed significant changes post-intervention with medium to large effect sizes. Most importantly, changes in emotion regulation processes were linked to improved eating psychopathology. The qualitative analysis corroborated this finding, highlighting how the intervention helped them form new beliefs about emotions, which helped them reduce ED behaviours. DISCUSSION Significant improvements in emotion processing and regulations, as well as psychopathology, along with positive qualitative feedback, suggest that the intervention effectively met its aims of increasing awareness of the link between emotions and eating psychopathology, providing help to identify and regulate emotions, and normalising emotional experiences. While our results are promising, further research is required to assess its effectiveness longer term and in clinical settings.

Abstract
BACKGROUND Throughout the COVID-19 pandemic, the number of individuals struggling with eating disorders (EDs) increased substantially. Body Brave (a not-for-profit) created and implemented a web-based stepped-care Recovery Support Programme (RSP) to improve access to community-based ED services. This quality improvement study describes the RSP and assesses its ability to deliver timely access to treatment and platform engagement. METHODS We conducted a retrospective cohort study comparing access to, and use of Body Brave services 6 months before and 12 months after implementation of the RSP platform (using 6-month increments for two postimplementation periods). Primary programme quality measures included registration requests, number of participants onboarded and time to access services; secondary measures included use of RSP action plans, attendance for recovery sessions and workshops, number of participants accessing treatment and text-based patient experience data. RESULTS A substantial increase in registration requests was observed during the first postimplementation period compared with the preimplementation period (176.5 vs 85.5; p=0.028). When compared with the preimplementation period, the second postimplementation observed a significantly larger percentage of successfully onboarded participants (76.6 vs 37.9; p<0.01) and a reduction in the number of days to access services (2 days vs 31 days; p<0.01). Although participant feedback rates were low, many users found the RSP helpful, easy to access, user-friendly and were satisfied overall. Users provided suggestions for improvement (eg, a platform instructional video, offer multiple times of day for live sessions and drop-in hours). CONCLUSIONS Although clinical benefit needs to be assessed, our findings demonstrate that the RSP enabled participants to quickly onboard and access initial services and have informed subsequent improvements. Understanding initial programme effects and usage will help assess the feasibility of adapting and expanding the RSP across Canada to address the urgent need for low-barrier, patient-centred ED care.

Abstract
OBJECTIVE Eating disorders are associated with significant illness burden and costs, yet access to evidence-based care is limited. Greater use of programme-led and focused interventions that are less resource-intensive might be part of the solution to this demand-capacity mismatch. METHOD In October 2022, a group of predominantly UK-based clinical and academic researchers, charity representatives and people with lived experience convened to consider ways to improve access to, and efficacy of, programme-led and focused interventions for eating disorders in an attempt to bridge the demand-capacity gap. RESULTS Several key recommendations were made across areas of research, policy, and practice. Of particular importance is the view that programme-led and focused interventions are suitable for a range of different eating disorder presentations across all ages, providing medical and psychiatric risk are closely monitored. The terminology used for these interventions should be carefully considered, so as not to imply that the treatment is suboptimal. CONCLUSIONS Programme-led and focused interventions are a viable option to close the demand-capacity gap for eating disorder treatment and are particularly needed for children and young people. Work is urgently needed across sectors to evaluate and implement such interventions as a clinical and research priority.

Abstract
BACKGROUND Family-based treatment (FBT) is currently the most effective evidence-based treatment approach for adolescents with anorexia nervosa (AN). Home treatment (HT) as an add-on to FBT (FBT-HT) has been shown to be acceptable, feasible and effective. The described three-arm randomized clinical trial (RCT) is intended to investigate whether FBT-HT demonstrates higher efficacy compared to standard outpatient FBT with supplemental mindfulness-based stress reduction training (FBT-MBSR). METHODS This RCT compares FBT-HT to standard outpatient FBT and FBT-MBSR as a credible home-based control group in terms of efficacy and delivery. Adolescents with AN or atypical AN disorder (n = 90) and their parent(s)/caregiver(s) are to be randomly assigned to either FBT, FBT-HT or FBT-MBSR groups. Eating disorder diagnosis and symptomatology are to be assessed by eating disorder professionals using standardized questionnaires and diagnostic instruments (Eating Disorder Examination, Eating Disorder Inventory, Body Mass Index). In addition, parents and caregivers independently provide information on eating behavior, intrafamily communication, stress experience and weight. The therapeutic process of the three treatments is to be measured and assessed among both participants and care providers. The feasibility, acceptability and appropriateness can thus also be evaluated. DISCUSSION We hypothesize that FBT-HT will be an acceptable, appropriate and feasible intervention and, importantly, will outperform both established FBT and FBT-MBSR in improving adolescent weight and negative eating habits. Secondary outcome measures include the reduction in the stress experienced by caregivers, as well as the regulation of perceived expressed emotions within the family, while the intrafamily relationships are hypothesized to mediate/moderate the effectiveness of FBT. The proposed study has the potential to enhance the scientific and clinical understanding of the efficacy of FBT for AN, including whether the addition of HT to FBT versus another home-based adjunct intervention improves treatment outcomes. Furthermore, the study aligns with public health priorities to optimize the outcomes of evidence-based treatments and integrate the community setting. Trial registration This study is registered at ClinicalTrials.gov (NCT05418075).

Abstract
BACKGROUND Empirically validated digital interventions for recurrent binge eating typically target numerous hypothesized change mechanisms via the delivery of different modules, skills, and techniques. Emerging evidence suggests that interventions designed to target and isolate one key change mechanism may also produce meaningful change in core symptoms. Although both 'broad' and 'focused' digital programs have demonstrated efficacy, no study has performed a direct, head-to-head comparison of the two approaches. We addressed this through a randomized non-inferiority trial. METHOD Participants with recurrent binge eating were randomly assigned to a broad (n = 199) or focused digital intervention (n = 199), or a waitlist (n = 202). The broad program targeted dietary restraint, mood intolerance, and body image disturbances, while the focused program exclusively targeted dietary restraint. Primary outcomes were eating disorder psychopathology and binge eating frequency. RESULTS In intention-to-treat analyses, both intervention groups reported greater improvements in primary and secondary outcomes than the waitlist, which were sustained at an 8-week follow-up. The focused intervention was not inferior to the broad intervention on all but one outcome, but was associated with higher rates of attrition and non-compliance. CONCLUSION Focused digital interventions that are designed to target one key change mechanism may produce comparable symptom improvements to broader digital interventions, but appear to be associated with lower engagement.

Abstract
OBJECTIVE Including the perspectives of individuals with lived experience of mental health issues is a critical step in research and treatment development. Focus groups with patients with a history of treatment for anorexia nervosa (AN) were conducted in anticipation of a clinical trial of Relapse Prevention and Changing Habits (REACH+). METHODS Seven female adults (23-51 years) who had previously received inpatient treatment for AN, now in remission, participated in one of two semistructured focus groups. Rapid qualitative analysis was used to examine participants' contributions and identify common topics. RESULTS Transcript analysis yielded three topics related to relapse prevention: (1) recovery aids, including a sense of agency in treatment decisions and finding new interests/passions, (2) recovery hindrances, such as lack of access to care, and (3) identification of members of support system. Aspects of REACH+ received positive feedback, such as continuity of care from the inpatient setting and the use of telehealth. Viewpoints differed with respect to the helpfulness of obtaining patient weights in treatment. The REACH+ online platform received positive comments regarding content and usability, as well as suggestions for additional content. DISCUSSION Qualitative feedback from patients with a history of AN highlighted the value of engaging patients in their own treatment decisions, as well as in treatment design and innovation. Within this small group, there were differences of opinion about treatment components, specifically weight assessment, that suggest the need for further data. User-centered design provides opportunities to improve the acceptability and, therefore, dissemination of novel treatments. PUBLIC SIGNIFICANCE Relapse prevention is a critical treatment need for patients with anorexia nervosa, as this illness too often follows a protracted course. There are challenges in both obtaining specialized care and in retaining patients in treatment. Here, patient perspectives on these challenges offer input to allow for optimization of relapse prevention treatment. Shared decision-making may be particularly valuable to support an individual's sense of agency and engagement in care.

Abstract
INTRODUCTION Military service members must maintain a certain body mass index and body fat percentage. Due to weight-loss pressures, some service members may resort to unhealthy behaviors that place them at risk for the development of an eating disorder (ED). OBJECTIVES To understand the scope and impact of EDs in military service members and veterans, we formed the Longitudinal Eating Disorders Assessment Project (LEAP) Consortium. LEAP aims to develop novel screening, assessment, classification, and treatment tools for veterans and military members with a focus on EDs and internalizing psychopathology. METHODS We recruited two independent nationally representative samples of post-9/11 veterans who were separated from service within the past year. Study 1 was a four-wave longitudinal survey and Study 2 was a mixed-methods study that included surveys, structured-clinical interviews, and qualitative interviews. RESULTS Recruitment samples were representative of the full population of recently separated veterans. Sample weights were created to adjust for sources of non-response bias to the baseline survey. Attrition was low relative to past studies of this population, with only (younger) age predicting attrition at 1-week follow-up. CONCLUSIONS We expect that the LEAP Consortium data will contribute to improved information about EDs in veterans, a serious and understudied problem.

Abstract
PURPOSE OF REVIEW With the current review, we provide a brief summary of recent literature that tests clinically observable characteristics at baseline that may impact treatment response, across eating disorder diagnoses. We then provide a critical discussion regarding how researchers may shift their approach to this research to improve treatment implications and generalizability of these findings. RECENT FINDINGS Recent work has broadly replicated prior findings suggesting a negative impact of lower weight status, poor emotion regulation, and early-life trauma on eating disorder treatment outcomes. Findings are more mixed for the relative contributions of illness duration, psychiatric comorbidity, and baseline symptom severity. Recent studies have begun to explore more specific domains of previously tested predictors (e.g., specific comorbidities) as well as previously neglected identity-related and systemic factors. However, recent research continues to use similar sampling techniques and approaches to analysis used in prior work. We propose that resolving remaining questions and illuminating predictors of treatment outcome in eating disorders requires a new approach to research sampling and study design. Suggested changes that can be applied within a traditional clinical trial framework may yield new insights with relevance across transdiagnostic eating disorder presentations.

Low intensity psychological interventions for the treatment of feeding and eating disorders: a systematic review and meta-analysis. J Eat Disord 2023; 11:56.

Abstract
BACKGROUND Feeding and eating disorders are associated with significant illness burden and costs, yet access to evidence-based care is limited. Low intensity psychological interventions have the potential to increase such access. METHODS A systematic review and meta-analysis were conducted on the use of low intensity psychological interventions for the treatment of feeding and eating disorders. Studies comparing low intensity psychological interventions against high intensity therapies and non-eating disorder specific psychological interventions were included, as well as those with waiting list control arms. There were three primary outcomes: eating disorder psychopathology, diagnostic and statistical manual of mental disorders (DSM) severity specifier-related outcomes and rates of remission/recovery. RESULTS Thirty-three studies met the inclusion criteria, comprising 3665 participants, and 30 studies were included in the meta-analysis. Compared to high intensity therapies, low intensity psychological interventions were equivalent on reducing eating disorder psychopathology (g = - 0.13), more effective at improving DSM severity specifier-related outcomes (g = - 0.15), but less likely to achieve remission/recovery (risk ratio (RR) = 0.70). Low intensity psychological interventions were superior to non-eating disorder specific psychological interventions and waiting list controls across all three primary outcomes. CONCLUSION Overall, findings suggest that low intensity psychological interventions can successfully treat eating disorder symptoms. Few potential moderators had a statistically significant effect on outcome. The number of studies for many comparisons was low and the methodological quality of the studies was poor, therefore results should be interpreted with caution. More research is needed to establish the effectiveness of low intensity psychological interventions for children and young people, as well as for individuals with anorexia nervosa, avoidant/restrictive food intake disorder, pica and rumination disorder.

Abstract
It is unclear whether offering individuals a choice between different digital intervention programs affects treatment outcomes. To generate initial insights, we conducted a pilot doubly randomized preference trial to test whether offering individuals with binge-spectrum eating disorder a choice between two digital interventions is causally linked with superior outcomes than random assignment to these interventions. Participants with recurrent binge eating were randomized to either a choice (n = 77) or no-choice (n = 78) group. Those in the choice group could choose one of the two digital programs, while those in the no-choice group were assigned a program at random. The two digital interventions (a broad and a focused program) took 4 weeks to complete, were based on cognitive-behavioral principles and have demonstrated comparable efficacy, but differ in scope, content, and targeted change mechanisms. Most participants (79%) allocated to the choice condition chose the broad program. While both groups experienced improvements in primary (Eating Disorder Examination Questionnaire global scores and number of binge eating episodes over the past month) and secondary outcomes (dietary restraint, body image concerns, etc.), no significant between-group differences were observed. The two groups did not differ on dropout rates, nor on most indices of intervention engagement. Findings provide preliminary insights towards the role of client preferences in digital mental health interventions for eating disorders. Client preferences may not determine outcomes when digital interventions are based on similar underlying principles, although larger trials are needed to confirm this.

Abstract
BACKGROUND Existing internet-based prevention and treatment programmes for binge eating are composed of multiple distinct modules that are designed to target a broad range of risk or maintaining factors. Such multi-modular programmes (1) may be unnecessarily long for those who do not require a full course of intervention and (2) make it difficult to distinguish those techniques that are effective from those that are redundant. Since dietary restraint is a well-replicated risk and maintaining factor for binge eating, we developed an internet- and app-based intervention composed solely of cognitive-behavioural techniques designed to modify dietary restraint as a mechanism to target binge eating. We tested the efficacy of this combined selective and indicated prevention programme in 403 participants, most of whom were highly symptomatic (90% reported binge eating once per week). METHOD Participants were randomly assigned to the internet intervention (n = 201) or an informational control group (n = 202). The primary outcome was objective binge-eating frequency. Secondary outcomes were indices of dietary restraint, shape, weight, and eating concerns, subjective binge eating, disinhibition, and psychological distress. Analyses were intention-to-treat. RESULTS Intervention participants reported greater reductions in objective binge-eating episodes compared to the control group at post-test (small effect size). Significant effects were also observed on each of the secondary outcomes (small to large effect sizes). Improvements were sustained at 8 week follow-up. CONCLUSIONS Highly focused digital interventions that target one central risk/maintaining factor may be sufficient to induce meaningful change in core eating disorder symptoms.

Epidemiology of eating disorders: population, prevalence, disease burden and quality of life informing public policy in Australia-a rapid review. J Eat Disord 2023; 11:23. [PMID: 36793104 PMCID: PMC9933292 DOI: 10.1186/s40337-023-00738-7] [Citation(s) in RCA: 19] [Impact Index Per Article: 19.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 01/22/2023] [Indexed: 02/17/2023] Open
Abstract
BACKGROUND Understanding of the epidemiology and health burden of eating disorders has progressed significantly in the last 2 decades. It was considered one of seven key areas to inform the Australian Government commissioned National Eating Disorder Research and Translation Strategy 2021-2031, as emerging research had highlighted a rise in eating disorder prevalence and worsening burden-of-illness. The aim of this review was to better understand the global epidemiology and impact of eating disorders to inform policy decision-making. METHODS Using a systematic Rapid Review methodology, ScienceDirect, PubMed and Medline (Ovid) were searched for peer-reviewed studies published between 2009 and 2021. Clear inclusion criteria were developed in consultation with experts in the field. Purposive sampling of literature was conducted, which predominately focused on higher-level evidence (meta-analyses, systematic reviews, and large epidemiological studies), synthesised, and narratively analysed. RESULTS 135 studies were deemed eligible for inclusion in this review (N = 1324). Prevalence estimates varied. Global Lifetime prevalence of any eating disorder ranged from 0.74 to 2.2% in males, and 2.58-8.4% in females. Australian 3-month point-prevalence of broadly defined disorders was around 16% in females. Eating disorders appeared more prevalent in young people and adolescents, particularly females (in Australia: eating disorders ~ 22.2%; disordered eating ~ 25.7%). Limited evidence was found on sex, sexuality and gender diverse (LGBTQI +) individuals, particularly males, who had a six-fold increase in prevalence compared to the general male population, with increased illness impact. Similarly, limited evidence on First Australian's (Aboriginal and Torres Strait Islander) suggests prevalence rates similar to non-Indigenous Australians. No prevalence studies were identified specifically assessing culturally and linguistically diverse populations. Global disease burden of any eating disorder was 43.4 age-standardised disability-adjusted-life-years per 100,000; increasing by 9.4% between 2007 and 2017. Australian's total economic cost was estimated at $84 billion from years-of-life lost due to disability and death, and annual lost earnings ~ $1.646 billion." CONCLUSIONS There is no doubt that eating disorder prevalence and impact are on the rise, particularly in at-risk and understudied populations. Much of the evidence came from female-only samples, and Western, high-income countries which more readily have access to specialised services. Future research should examine more representative samples. There is an urgent need for more refined epidemiological methods to better understand these complex illnesses over time, to guide health policy and development-of-care.

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
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
PURPOSE Dietitians are important members of eating disorder treatment teams. Previous research indicates little is known about the experience of receiving nutrition care for eating disorders. This study aimed to explore the perspectives of consumers and carers regarding the care received from primary care dietitians for eating disorders. METHODS This study qualitatively explored the perceptions of individuals aged ≥ 15 years, who (i) identified as having an eating disorder or (ii) had cared for someone with an eating disorder, and had received care from a dietitian in a primary care setting. Thematic analysis was used to identify themes from interview transcripts. Synthesized member checking was utilized to assess whether the identified themes resonated with participants' experiences. Twenty-four individuals (21 consumers, 3 carers) participated in a semi-structured interview. Seventeen participants completed member checking and all supported the identified themes and subthemes. RESULTS Three themes emerged inductively from the data: (1) valuing a person-centered approach to dietetic care; (2) the therapeutic alliance is central to engaging in dietetic care; and (3) sharing the complex journey. CONCLUSIONS This study advances the understanding of the aspects of dietetic care perceived as most helpful by consumers and carers. These insights highlight the importance of person-centeredness, empathy, trust and collaboration within eating disorder care. The findings can be used by dietitians and health professionals to inform practice. Further research is needed to understand how dietitians can be supported to provide optimal nutrition care to people and families impacted by eating disorders. LEVEL OF EVIDENCE V. Qualitative study.

Abstract
PURPOSE Guided self-help (GSH) treatments have the capacity to expand access to care, decrease costs, and increase dissemination compared to traditional therapist-directed treatment approaches. However, little is known about parent and clinician perspectives about the acceptability of GSH for adolescents with eating disorders. METHODS This study utilized a mixed methods approach to obtain qualitative and quantitative data regarding clinician and participants' experiences with GSH. Parent participants were enrolled in a randomized trial comparing GSH family-based treatment (GSH-FBT) to family-based treatment delivered via videoconferencing (FBT-V) for adolescents (12-18 years old) with a DSM-5 diagnosis of anorexia nervosa (AN). Parent participants provided qualitative feedback using the Helping Alliances Questionnaire about their experience of treatment. Clinician participants were six master's or PhD-level therapists. These clinicians were trained in and provided both treatments (GSH-FBT and FBT-V). They provided responses to questionnaires and participated in a 1-h focus group about their experience as treatment providers. RESULTS Regardless of treatment condition, parents listed more improvement than worsening of symptoms in their child with AN. Clinicians reported lower scores on competency and comfort metrics with GSH-FBT compared to FBT-V. Qualitatively, clinicians reported both advantages and disadvantages of delivering GSH-FBT. CONCLUSION Further studies are needed to better understand how GSH interventions can be disseminated to patients and families, particularly those with limited access to specialized eating disorder treatment centers. Level of evidence Level I, data collected as part of a randomized controlled trial.

Abstract
OBJECTIVE Many individuals with an eating disorder do not receive appropriate care. Low-threshold interventions could help bridge this treatment gap. The study aim was to evaluate the effectiveness of Featback, a fully automated online self-help intervention, online expert-patient support and their combination. METHOD A randomized controlled trial with a 12-month follow-up period was conducted. Participants aged 16 or older with at least mild eating disorder symptoms were randomized to four conditions: (1) Featback, a fully automated online self-help intervention, (2) chat or email support from a recovered expert patient, (3) Featback with expert-patient support and (4) a waiting list control condition. The intervention period was 8 weeks and there was a total of six online assessments. The main outcome constituted reduction of eating disorder symptoms over time. RESULTS Three hundred fifty five participants, of whom 43% had never received eating disorder treatment, were randomized. The three active interventions were superior to a waitlist in reducing eating disorder symptoms (d = -0.38), with no significant difference in effectiveness between the three interventions. Participants in conditions with expert-patient support were more satisfied with the intervention. DISCUSSION Internet-based self-help, expert-patient support and their combination were effective in reducing eating disorder symptoms compared to a waiting list control condition. Guidance improved satisfaction with the internet intervention but not its effectiveness. Low-threshold interventions such as Featback and expert-patient support can reduce eating disorder symptoms and reach the large group of underserved individuals, complementing existing forms of eating disorder treatment. PUBLIC SIGNIFICANCE STATEMENT Individuals with eating-related problems who received (1) a fully automated internet-based intervention, (2) chat and e-mail support by a recovered individual or (3) their combination, experienced stronger reductions in eating disorder symptoms than those who received (4) usual care. Such brief and easy-access interventions play an important role in reaching individuals who are currently not reached by other forms of treatment.

Abstract
OBJECTIVES Anorexia Nervosa (AN) is a severe psychiatric disorder and knowledge about the cost-effectiveness of potential interventions is limited. The aim of this paper is to introduce the Trimbos Institute health economic cost-effectiveness model for Anorexia Nervosa (AnoMod-TI), a flexible modelling tool for assessing the long-term cost-effectiveness of interventions for AN in late adolescent and adult patients, which could support clinical decision making. METHODS AnoMod-TI is a state-transition cohort simulation (Markov) model developed from a Dutch societal perspective, which consists of four health states - namely full remission (FR), partial remission (PR), AN and death. Results are expressed as total healthcare costs, QALYs and incremental cost-effectiveness ratio. RESULTS For the purpose of demonstrating AnoMod-TI and how it could be used to estimate cost-effectiveness over a 20-year time horizon, it was applied to a hypothetical treatment scenario. Results illustrate how a relatively costly intervention with only modest effects can still be cost-effective in the long term. CONCLUSIONS AnoMod -TI can be used to examine long-term cost-effectiveness of various interventions aimed at either treating AN or preventing relapse from a state of partial or full remission. AnoMod-TI is freely available upon request to the authors.

Experiencing eight psychotherapy approaches devoted to eating disorders in a single-day workshop increases insight and motivation to engage in care: a pilot study. Eat Weight Disord 2022; 27:2213-2222.

Abstract
PURPOSE For patients with eating disorders (EDs), early engagement in care is usually considered a positive prognostic factor. The aim of the study was to investigate how a single-day intervention devoted to early, brief, experiential exposure to a variety of psychotherapy approaches might support commitment to change and the decision to engage in care in patients with EDs. METHODS One hundred and sixty-nine adult outpatients newly diagnosed with an ED took part in a single-day workshop for groups of up to ten patients, where they experienced eight psychotherapeutic approaches. Motivation to change care and level of insight were assessed at baseline and 10 days after the intervention. RESULTS Motivation and commitment to take active steps toward change (expressed by the "Committed Action" composite score) significantly improved after the intervention (p < 0.001), and a significant number of patients specifically moved from "contemplation" to "action" stage (p < 0.001). The improvement of motivation to change was significantly associated with an increase in insight capacity (p < 0.001), and this increase was observed for almost all related dimensions such as recognition of illness or awareness of need for psychological treatment. CONCLUSION A single-day session devoted to experiencing a range of group psychotherapies increased patients' insight and motivation to actively engage in care. To confirm potential longer-term benefits of this intervention, further studies are needed to explore the contribution of each approach and process specifically involved in patients' increased motivation for care, as well as the clinical characteristics of patients associated with better outcomes. LEVEL OF EVIDENCE V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Abstract
OBJECTIVE The primary aim was assessing the cost-effectiveness of an internet-based self-help program, expert-patient support, and the combination of both compared to a care-as-usual condition. METHOD An economic evaluation from a societal perspective was conducted alongside a randomized controlled trial. Participants aged 16 or older with at least mild eating disorder symptoms were randomly assigned to four conditions: (1) Featback, an online unguided self-help program, (2) chat or e-mail support from a recovered expert patient, (3) Featback with expert-patient support, and (4) care-as-usual. After a baseline assessment and intervention period of 8 weeks, five online assessments were conducted over 12 months of follow-up. The main result constituted cost-utility acceptability curves with quality-of-life adjusted life years (QALYs) and societal costs over the entire study duration. RESULTS No significant differences between the conditions were found regarding QALYs, health care costs and societal costs. Nonsignificant differences in QALYs were in favor of the Featback conditions and the lowest societal costs per participant were observed in the Featback only condition (€16,741) while the highest costs were seen in the care-as-usual condition (€28,479). The Featback only condition had the highest probability of being efficient compared to the alternatives for all acceptable willingness-to-pay values. DISCUSSION Featback, an internet-based unguided self-help intervention, was likely to be efficient compared to Featback with guidance from an expert patient, guidance alone and a care-as-usual condition. Results suggest that scalable interventions such as Featback may reduce health care costs and help individuals with eating disorders that are currently not reached by other forms of treatment. PUBLIC SIGNIFICANCE STATEMENT Internet-based interventions for eating disorders might reach individuals in society who currently do not receive appropriate treatment at low costs. Featback, an online automated self-help program for eating disorders, was found to improve quality of life slightly while reducing costs for society, compared to a do-nothing approach. Consequently, implementing internet-based interventions such as Featback likely benefits both individuals suffering from an eating disorder and society as a whole.

Abstract
BACKGROUND Although effective treatments exist for diagnostic and subthreshold-level eating disorders (EDs), a significant proportion of affected individuals do not receive help. Interventions translated for delivery through smartphone apps may be one solution towards reducing this treatment gap. However, evidence for the efficacy of smartphones apps for EDs is lacking. We developed a smartphone app based on the principles and techniques of transdiagnostic cognitive-behavioral therapy for EDs and evaluated it through a pre-registered randomized controlled trial. METHODS Symptomatic individuals (those who reported the presence of binge eating) were randomly assigned to the app (n = 197) or waiting list (n = 195). Of the total sample, 42 and 31% exhibited diagnostic-level bulimia nervosa and binge-eating disorder symptoms, respectively. Assessments took place at baseline, 4 weeks, and 8 weeks post-randomization. Analyses were intention-to-treat. The primary outcome was global levels of ED psychopathology. Secondary outcomes were other ED symptoms, impairment, and distress. RESULTS Intervention participants reported greater reductions in global ED psychopathology than the control group at post-test (d = -0.80). Significant effects were also observed for secondary outcomes (d's = -0.30 to -0.74), except compensatory behavior frequency. Symptom levels remained stable at follow-up. Participants were largely satisfied with the app, although the overall post-test attrition rate was 35%. CONCLUSION Findings highlight the potential for this app to serve as a cost-effective and easily accessible intervention for those who cannot receive standard treatment. The capacity for apps to be flexibly integrated within current models of mental health care delivery may prove vital for addressing the unmet needs of people with EDs.

Screening, assessment and diagnosis in the eating disorders: findings from a rapid review. J Eat Disord 2022; 10:78. [PMID: 35672777 PMCID: PMC9175461 DOI: 10.1186/s40337-022-00597-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 05/21/2022] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND Limited screening practices, minimal eating disorder training in the healthcare professions, and barriers related to help-seeking contribute to persistent low rates of eating disorder detection, significant unmet treatment need, and appreciable associated disease burden. The current review sought to broadly summarise the literature and identify gaps relating to the screening, assessment, and diagnosis of eating disorders within Western healthcare systems. METHODS This paper forms part of a Rapid Review series scoping the evidence base for the field of eating disorders, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for studies published between 2009 and mid 2021 in English. High-level evidence such as meta-analyses, large population studies and Randomised Control Trials were prioritised through purposive sampling. Data from selected studies relating to Screening, Assessment and Diagnosis of eating disorders were synthesised and are disseminated in the current review. RESULTS Eighty seven studies were identified, 38% relating to screening and 62% to assessment and diagnosis. The majority of screening studies were conducted in university student samples, showing high prevalence but only modest improvements in help-seeking in those studies that followed up post-screen. In healthcare settings, clinicians continue to have difficulty identifying eating disorder presentations, particularly Binge Eating Disorder, Other Specified Feeding or Eating Disorders, and sub-threshold eating disorders. This is preceded by inadequate and frequently homogenous screening mechanisms and exacerbated by considerable personal and health-system barriers, including self-stigma and lack of resourcing. While all groups are at risk of delayed or no diagnosis, those at particular risk include LGBTQ+ and gender diverse individuals, individuals living in larger bodies, and males. CONCLUSIONS A majority of individuals with eating disorders remain undiagnosed and untreated despite a high prevalence of these conditions and increased advocacy in recent years. Research into improving detection and clinician diagnostic skill is extremely limited. Innovative empirical research is strongly recommended to address significant individual and health-system barriers currently preventing appropriate and timely intervention for many. Limited screening in healthcare settings and low rates of eating disorder training in the healthcare professions are just some of the barriers to help-seeking which may contribute to delayed intervention and diagnosis in the eating disorders. This has significant impacts, prolonging treatment when it is finally received, and increasing healthcare costs for both the individual and the healthcare system. The current review is part of a larger Rapid Review series conducted to inform the development of Australia's National Eating Disorders Research and Translation Strategy 2021-2031. A Rapid Review is designed to comprehensively summarise a body of literature in a short timeframe, often to guide policy-making and address urgent health concerns. The Rapid Review synthesises the current evidence-base and identifies gaps in eating disorder research and care, in order to guide decision making and address urgent health concerns. This paper gives a critical overview of the scientific literature relating to the current state of screening, assessment, and diagnosis of eating disorders within Western healthcare systems that may inform health policy and research in an Australian context. It covers screening initiatives in both general and high-risk populations; personal, clinician and healthcare system challenges relating to help-seeking; and obstacles to accurate and timely clinical diagnosis across the eating disorders.

Abstract
OBJECTIVE Digital interventions show promise to address eating disorder (ED) symptoms. However, response rates are variable, and the ability to predict responsiveness to digital interventions has been poor. We tested whether machine learning (ML) techniques can enhance outcome predictions from digital interventions for ED symptoms. METHOD Data were aggregated from three RCTs (n = 826) of self-guided digital interventions for EDs. Predictive models were developed for four key outcomes: uptake, adherence, drop-out, and symptom-level change. Seven ML techniques for classification were tested and compared against the generalized linear model (GLM). RESULTS The seven ML methods used to predict outcomes from 36 baseline variables were poor for the three engagement outcomes (AUCs = 0.48-0.52), but adequate for symptom-level change (R2 = .15-.40). ML did not offer an added benefit to the GLM. Incorporating intervention usage pattern data improved ML prediction accuracy for drop-out (AUC = 0.75-0.93) and adherence (AUC = 0.92-0.99). Age, motivation, symptom severity, and anxiety emerged as influential outcome predictors. CONCLUSION A limited set of routinely measured baseline variables was not sufficient to detect a performance benefit of ML over traditional approaches. The benefits of ML may emerge when numerous usage pattern variables are modeled, although this validation in larger datasets before stronger conclusions can be made.

Abstract
OBJECTIVE 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. METHOD 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. RESULTS 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). CONCLUSION 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.

Abstract
OBJECTIVE This study examines, inpatient treatment costs, and typical treatment courses of patients with an eating disorder using secondary data. METHOD The data were provided by a German health insurance company (data from 4.2 million members from 2004 to 2010; corresponds to a market share of 6% of all statutorily insured persons in Germany). An age and gender matched control group without an eating disorder diagnosis was assessed for comparisons from the same dataset. RESULTS Two thousand seven hundred and thirty four cases with an eating disorder diagnosis (anorexia nervosa [AN], bulimia nervosa [BN] or combination [ANBN]) were identified. The inpatient costs of treatment were €5471.15 for BN, €9080.26 for AN, €10,809.16 for ANBN and €339.37 for the control group. Interestingly, there are numerous mild episodes of eating disorders that could be successfully treated solely on an outpatient basis with a short treatment duration. CONCLUSION Our findings suggest that course and severity of eating disorders can vary from mild to very severe. Data from health insurance companies depict rather different disease and treatment courses than studies on primary data derived from treatment institutions.

Abstract
Advances in machine learning and digital data provide vast potential for mental health predictions. However, research using machine learning in the field of eating disorders is just beginning to emerge. This paper provides a narrative review of existing research and explores potential benefits, limitations, and ethical considerations of using machine learning to aid in the detection, prevention, and treatment of eating disorders. Current research primarily uses machine learning to predict eating disorder status from females' responses to validated surveys, social media posts, or neuroimaging data often with relatively high levels of accuracy. This early work provides evidence for the potential of machine learning to improve current eating disorder screening methods. However, the ability of these algorithms to generalise to other samples or be used on a mass scale is only beginning to be explored. One key benefit of machine learning over traditional statistical methods is the ability of machine learning to simultaneously examine large numbers (100s to 1000s) of multimodal predictors and their complex non-linear interactions, but few studies have explored this potential in the field of eating disorders. Machine learning is also being used to develop chatbots to provide psychoeducation and coping skills training around body image and eating disorders, with implications for early intervention. The use of machine learning to personalise treatment options, provide ecological momentary interventions, and aid the work of clinicians is also discussed. Machine learning provides vast potential for the accurate, rapid, and cost-effective detection, prevention, and treatment of eating disorders. More research is needed with large samples of diverse participants to ensure that machine learning models are accurate, unbiased, and generalisable to all people with eating disorders. There are important limitations and ethical considerations with utilising machine learning methods in practice. Thus, rather than a magical solution, machine learning should be seen as an important tool to aid the work of researchers, and eventually clinicians, in the early identification, prevention, and treatment of eating disorders.

Cost-of-illness for non-underweight binge-eating disorders. Eat Weight Disord 2022; 27:1377-1384. [PMID: 34327651 PMCID: PMC9079013 DOI: 10.1007/s40519-021-01277-3] [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: 05/19/2021] [Accepted: 07/22/2021] [Indexed: 11/23/2022] Open
Abstract
PURPOSE This study examined economic costs associated with untreated eating disorders (EDs) characterised by regular binge eating in the absence of low weight. Both direct and indirect costs were assessed, reporting a limited societal perspective of economic impact as some costs were not included. METHODS One hundred and twenty six adults seeking treatment for recurrent binge eating were asked to report impairment associated with an ED. Costs were calculated using 2017 prices, including an examination of variables associated with costs. RESULTS Estimated societal costs for the year preceding assessment were £3268.47 (€3758.54) per person. In multivariate analyses, no reliable baseline associates of cost were identified. CONCLUSION The economic burden of EDs characterised by regular binge eating is significant, and underscores the need for efficacious and cost-effective treatments. Individuals with binge-eating disorders report work impairment and healthcare use that may cost the United Kingdom economy upwards of £3.5 billion (€4bn) per annum. Further studies should consider academic impairment and the economic impact of EDs on families. LEVEL OF EVIDENCE III: evidence obtained from well-designed cohort or case-control analytic studies.

Randomized Controlled Comparison of an Internet-Based Intervention for Eating Disorder Symptoms With and Without Interactive Functionality. Behav Ther 2022; 53:508-520.

Abstract
Despite their potential as a scalable, cost-effective intervention format, self-guided Internet-based interventions for eating disorder (ED) symptoms continue to be associated with suboptimal rates of adherence and retention. Improving this may depend on the design of an Internet intervention and its method of content delivery, with interactive programs expected to be more engaging than static, text-based programs. However, causal evidence for the added benefits of interactive functionality is lacking. We conducted a randomized controlled comparison of an Internet-based intervention for ED symptoms with and without interactive functionality. Participants were randomized to a 4-week interactive (n = 148) or static (n = 145) version of an Internet-based, cognitive-behavioral program. The interactive version included diverse multimedia content delivery channels (video tutorials, graphics, written text), a smartphone app allowing users to complete the required homework exercises digitally (quizzes, symptom tracking, self-assessments), and progress monitoring features. The static version delivered identical intervention content but only via written text, and contained none of those interactive features. Dropout rates were high overall (58%), but were significantly-yet slightly-lower for the interactive (51%) compared to the static intervention (65%). There were no significant differences in adherence rates and symptom-level improvements between the two conditions. Adding basic interactive functionality to a digital intervention may help with study retention. However, present findings challenge prior speculations that interactive features are crucial for enhancing user engagement and symptom improvement.

Abstract
Motivation to change behavior is seen as an important factor in achieving a better treatment effect in patients with eating disorders (ED). The aim of this systematic review was to assess whether motivational interviewing (MI) and motivational enhancement therapy (MET) might (1) increase motivation to change behavior and (2) improve eating disorder psychopathology (EDP) and body mass index (BMI) in patients with ED. To investigate this, a literature search was conducted on 9 March 2021 on four scientific databases: Cochrane, Embase (Ovid), MEDLINE (PubMed), and PsycInfo (EBSCO). A total of 2647 publications were identified and following a rigorous stepwise procedure to assess titles and abstracts and, thereafter, full texts of relevant publications, 13 studies were included in the data extraction and analyses. A few individual studies (n = 5) found a significant increase in motivation, two a decrease in ED symptoms (n = 2), while none found an effect on BMI. However, the meta-analysis of each outcome found effect sizes near zero, thereby confirming the results of previous narrative reviews that have described a lack of effect of MET/MI on motivation in ED. Since the individual studies differ substantially in design, and the outcomes were inconsistently assessed with regards to instruments and duration, the effect of MET/MI on motivation for behavioral change, ED psychopathology, and BMI is still unclear.

Abstract
OBJECTIVE Eating disorders (EDs) were once conceptualized as primarily affecting affluent, White women, a misconception that informed research and practice for many years. Abundant evidence now discredits this stereotype, but it is unclear if prevailing "evidence-based" treatments have been evaluated in samples representative of the diversity of individuals affected by EDs. Our goal was to evaluate the reporting, inclusion, and analysis of sociodemographic variables in ED psychotherapeutic treatment randomized controlled trials (RCTs) in the US through 2020. METHODS We conducted a systematic review of ED psychotherapeutic treatment RCTs in the US and examined the reporting and inclusion of gender identity, age, race/ethnicity, sexual orientation, and socioeconomic status (SES) of enrolled participants, as well as recruitment methods, power analyses, and discussion of limitations and generalizability. RESULTS Our search yielded 58 studies meeting inclusion criteria dating back to 1985. Reporting was at times incomplete, absent, or centered on the racial/gender majority group. No studies reported gender diverse participants, and men and people of color were underrepresented generally, with differences noted across diagnoses. A minority of papers considered sociodemographic variables in analyses or acknowledged limitations related to sample characteristics. Some progress was made across the decades, with studies increasingly providing full racial and ethnic data, and more men included over time. Although racial and ethnic diversity improved somewhat, progress appeared to stall in the last decade. DISCUSSION We summarize findings, consider context and challenges for RCT researchers, and offer suggestions for researchers, journal editors, and reviewers on improving representation, reporting, and analytic practices. PUBLIC SIGNIFICANCE Randomized controlled trials of eating disorder psychotherapeutic treatment in the US are increasingly reporting full race/ethnicity data, but information on SES is inconsistent and sexual orientation absent. White women still comprise the overwhelming majority of participants, with few men and people of color, and no gender-diverse individuals. Findings underscore the need to improve reporting and increase representation to ensure evidence-based treatments are effective across and within diverse groups.

Abstract
Background Although binge eating disorder (BED) is the most common eating pathology and carries a high mental and physical burden, access to specialized treatment is limited due to patient-related barriers and insufficient healthcare resources. Integrating web-based self-help programs into clinical care for BED may address this treatment gap by making evidence-based eating disorder interventions more accessible. Methods A two-armed randomized controlled trial will be conducted to evaluate the effectiveness of a web-based self-help intervention for BED in routine care settings. Patients aged 18-65 years fulfilling the diagnostic criteria for BED (N = 152) will be randomly allocated to (1) an intervention group receiving a 12-week web-based self-help program or (2) a waitlist control group with delayed access to the intervention. The primary outcome will be the number of binge eating episodes. Secondary outcomes include global eating pathology, functional impairments, work capacity, well-being, comorbid psychopathology, self-esteem, and emotion regulation abilities. Measurements will be conducted at baseline (study entrance), 6 weeks after baseline (mid-treatment), and 12 weeks after baseline (post-treatment). To capture outcomes and treatment mechanisms in real-time, traditional self-reports will be combined with weekly symptom monitoring and ecological momentary assessment. Discussion Evaluating the effectiveness of web-based interventions is essential to overcome the treatment gap for patients with BED. When adequately integrated into standard care, these programs have the potential to alleviate the high burden of BED for individuals, their families, and society.

Abstract
BACKGROUND Individuals with bulimia nervosa (BN) experience persistent episodes of binge eating and inappropriate compensatory behavior associated with impaired physical and mental health. Despite the existence of effective treatments, many individuals with BN remain untreated, leading to a high burden and an increased risk of chronicity. Web-based interventions may help facilitate access to evidence-based treatments for BN by reducing barriers to the health care system. METHODS The present study will investigate the effectiveness of a web-based self-help intervention for BN in a two-armed randomized controlled trial. Individuals diagnosed with BN (N = 152) will be randomly assigned to either (1) an intervention group receiving a 12-week web-based intervention or (2) a waitlist control group with delayed access to the intervention. Further assessments will be scheduled 6 (mid-treatment) and 12 (post-treatment) weeks after baseline. Changes in the number of binge eating episodes and compensatory behaviors will be examined as primary outcomes. Secondary outcomes include global eating pathology, functional impairments, well-being, comorbid psychopathology, self-esteem, and emotion regulation abilities. DISCUSSION Adding web-based interventions into routine care is a promising approach to overcome the existing treatment gap for patients with BN. Therefore, the current study will test the effectiveness of a web-based intervention for BN under standard clinical care settings.

Abstract
The COVID-19 pandemic has profoundly disrupted people's daily life and contributed to adverse health and mental health outcomes. People with pre-existing mental health conditions are particularly likely to experience symptom exacerbation. Complementing the adverse impacts of the pandemic are eating disorder specific risk factors for worsening of eating disorder symptoms and/or impeding treatment progress and recovery. For this joint Virtual Issue, we selected 15 articles that have been published in two leading journals in the field of eating disorders (International Journal of Eating Disorders and Journal of Eating Disorders) to highlight studies that offer information about individuals' lived experience with an eating disorder during the COVID-19 pandemic. In these studies, most participants reported worsening of eating disorder symptoms which they attributed to challenges arising from changes in daily routines including eating and exercise related habits, increased stress, and diminished social contacts. These research findings reported a mixed picture about patients' perceptions of the ease of the transition to virtual delivery of treatment and the quality of care they received during the pandemic. Qualitative studies suggested strategies for supporting people with eating disorders during pandemic conditions, with some of these holding promise for improving care for individuals who experience an eating disorder.

Abstract
The COVID-19 pandemic has potentially increased the risk for adolescent depression. Even pre-pandemic, <50% of youth with depression accessed care, highlighting needs for accessible interventions. Accordingly, this randomized controlled trial (ClinicalTrials.gov: NCT04634903 ) tested online single-session interventions (SSIs) during COVID-19 in adolescents with elevated depression symptoms (N = 2,452, ages 13-16). Adolescents from all 50 US states, recruited via social media, were randomized to one of three SSIs: a behavioural activation SSI, an SSI teaching that traits are malleable and a supportive control. We tested each SSI's effects on post-intervention outcomes (hopelessness and agency) and three-month outcomes (depression, hopelessness, agency, generalized anxiety, COVID-19-related trauma and restrictive eating). Compared with the control, both active SSIs reduced three-month depressive symptoms (Cohen's d = 0.18), decreased post-intervention and three-month hopelessness (d = 0.16-0.28), increased post-intervention agency (d = 0.15-0.31) and reduced three-month restrictive eating (d = 0.12-17). Several differences between active SSIs emerged. These results confirm the utility of free-of-charge, online SSIs for high-symptom adolescents, even in the high-stress COVID-19 context.

Abstract
Objective This pilot study examines the feasibility and the effectiveness of add‐on home treatment (HT) to family‐based treatment (FBT) in adolescents with anorexia nervosa (AN). The HT intervention is delivered by specialised nurses and aims at supporting patients and parents to re‐establish family meals in the home environment. Method We performed a 3‐month study in AN patients with a waiting‐list control design comparing 45 (43 females, 2 males) adolescents receiving FBT augmented with HT compared to 22 (21 females, 1 male) participants receiving FBT alone on the waiting list for additional HT. Eating disorder diagnosis, psychopathology and severity of clinical symptoms were assessed using the Eating Disorder Examination (EDE) interview, the Eating Disorders Inventory (EDI‐2) and clinical parameters (BMI, menstrual status, level of over‐exercising) at baseline and after 3 months. Results After 3 months of treatment, both treatment groups showed a significant early weight gain, a reduction in the rate of AN diagnoses assessed with the EDE interview and a reduction in EDI‐2 total scores. The combined HT/FBT group showed a significantly greater increase in BMI than the FBT‐only group. In the combined HT/FBT group, none of the patients had to be admitted to hospital, while three (13.6%) of the FBT‐only group had to be referred to inpatient treatment. Discussion Our results suggest that HT augmented FBT might be useful compared to FBT alone in terms of early weight gain and might reduce the risk of hospital admission in adolescent AN. Home treatment as an add‐on to family‐based treatment seems to be a well‐accepted and very effective method for the treatment of eating disorders in adolescence. Combining family‐based treatment with home treatment thus seems to even enhance the therapy effectiveness of FBT in terms of initial weight gain as well as psychopathology
