Abstract
OBJECTIVE Internet-Based Cognitive Behavioral Therapy (iCBT) is an innovative modality of cognitive-behavioral intervention that presents a promising therapeutic strategy for individuals diagnosed with binge spectrum eating disorders. This study employed a meta-analysis methodology to assess the clinical effectiveness and acceptability of iCBT. METHODS We conducted searches in databases such as PubMed, Embase, Web of Science, Cochrane Library, and PsycINFO, collecting literature that met the inclusion criteria until August 5, 2023. RESULTS A comprehensive analysis was conducted, encompassing a total of 11 randomized controlled studies that satisfied the predetermined criteria for inclusion. The summary results demonstrated that iCBT could significantly improve the pathological features related to eating in patients with binge spectrum eating disorders and also significantly reduce the frequency of binge episodes. Additionally, iCBT could ameliorate the depressive and anxious emotions of patients with binge spectrum eating disorders and boost their self-esteem. Furthermore, a notable disparity in dropout rates was seen in comparison to the control group. LIMITATION Heterogeneity across studies,limitations of self-assessment scales and potential publication bias. CONCLUSION iCBT can effectively assist patients with binge spectrum eating disorders in improving clinical symptoms. However, it is important to use caution when interpreting the findings of this study, as there are limitations pertaining to the quantity and quality of the included studies.

Abstract
Eating disorders (EDs) are undertreated worldwide. In the UK the lag between recognition of symptoms and treatment ranges from about 15 months to in excess of 2 years. Internet-based cognitive behaviour therapy (ICBT) could be a viable alternative to face-to-face cognitive behaviour therapy (CBT) that avoids the negative impacts of delayed interventions. Based on evidence from randomised controlled trials (RCTs), this systematic review investigated the efficacy of minimally guided self-help ICBT, without face-to-face therapy, for the prevention, treatment and relapse prevention of all types of EDs in adults. The electronic databases MEDLINE, PsychINFO, CENTRAL, Scopus, and Web of Science were searched between 1991 and 2021. Inclusion criteria specified RCTs with ICBT versus inactive comparison groups. The Cochrane Risk of Bias Tool-2 was used for quality assessments. Qualitative synthesis and meta-analyses were conducted. Findings typically showed medium significant beneficial effect sizes for prevention studies ranging from (-0.31 [95% CI: -0.57, -0.06] to -0.47 [95% CI: -0.82, -0.11]) and generally large effect sizes for the treatment studies ranging from (-0.30 [95% CI: -0.57, -0.03] to -1.11 [95% CI: -1.47, -0.75]). Relapse prevention studies yielded mainly small non-significant beneficial effects with significant effect sizes of (-0.29 [95% CI: -0.56, -0.03] and -0.43 [95% CI: -0.70, -0.16]). Only the treatment studies reached clinical significance and cognitive symptoms improved more than behavioural symptoms. ICBT appears to be efficacious for the prevention, treatment and relapse prevention of eating disorders with treatment interventions being the most beneficial. However, the evidence base is very small, particularly for treatment and relapse prevention, indicating the need for more high-quality RCTs.

Abstract
Eating disorders are severe and often chronic mental illnesses that are associated with high impairment and mortality rates. Recent estimates suggest that eating disorder prevalence rates are on the rise, indicating an increased need for accurate assessment and detection. The current review provides an overview of transdiagnostic eating disorder assessments, including interview, self-report, health and primary care screeners, and technology-based and objective assessments. We focused on assessments that are transdiagnostic in nature and exhibit high impact in the field. We provide recommendations for how these assessments should be used in research and clinical settings. We also discuss considerations that are crucial for assessment, including the use of a categorical versus dimensional diagnostic framework, assessment of eating disorders in related fields (i.e., anxiety and depression), and measurement-based care for eating disorders. Finally, we provide suggestions for future research, including the need for more research on short transdiagnostic screeners for use in health care settings, standardized assessments for ecological momentary assessment, development of state-based assessment of eating disorder symptoms, and consideration of assessment across multiple timescales.

Abstract
BACKGROUND Psychotherapy is considered central to the effective treatment of eating disorders-focusing on behavioural, psychological, and social factors that contribute to the illness. Research indicates psychotherapeutic interventions out-perform placebo, waitlist, and/or other treatments; but, outcomes vary with room for major improvement. Thus, this review aims to (1) establish and consolidate knowledge on efficacious eating disorder psychotherapies; (2) highlight select emerging psychotherapeutic interventions; and (3) identify knowledge gaps to better inform future treatment research and development. METHODS The current review forms part of a series of Rapid Reviews published in a special issue in the Journal of Eating Disorders to inform the development of the Australian-government-funded National Eating Disorder Research and Translation Strategy 2021-2031. Three databases were searched for studies published between 2009 and 2023, published in English, and comprising high-level evidence studies (meta-analyses, systematic reviews, moderately sized randomised controlled studies, moderately sized controlled-cohort studies, and population studies). Data pertaining to psychotherapies for eating disorders were synthesised and outlined in the current paper. RESULTS 281 studies met inclusion criteria. Behavioural therapies were most commonly studied, with cognitive-behavioural and family-based therapies being the most researched; and thus, having the largest evidence-base for treating anorexia nervosa, bulimia nervosa, and binge eating disorder. Other therapies, such as interpersonal and dialectical behaviour therapies also demonstrated positive treatment outcomes. Emerging evidence supports specific use of Acceptance and Commitment; Integrative Cognitive Affective; Exposure; Mindfulness; and Emotionally-Focused therapies; however further research is needed to determine their efficacy. Similarly, growing support for self-help, group, and computer/internet-based therapeutic modalities was noted. Psychotherapies for avoidant/restrictive food intake disorder; other, and unspecified feeding and eating disorders were lacking evidence. CONCLUSIONS Currently, clinical practice is largely supported by research indicating that behavioural and cognitive-behavioural psychotherapies are most effective for the treatment of eating disorders. However, the efficacy of psychotherapeutic interventions varies across studies, highlighting the need for investment and expansion of research into enhanced variants and novel psychotherapies to improve illness outcomes. There is also a pressing need for investigation into the whole range of eating disorder presentations and populations, to determine the most effective interventions.

The acceptability, feasibility, and preliminary efficacy of a supported online self-help treatment program for binge-eating disorder. Front Psychiatry 2023; 14:1229261. [PMID: 37860164 PMCID: PMC10584326 DOI: 10.3389/fpsyt.2023.1229261] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 09/06/2023] [Indexed: 10/21/2023] Open
Abstract
Introduction Studies in transdiagnostic eating disorder (ED) samples suggest supported online self-help programs (eTherapies) are effective and may improve access to treatment; however, their evaluation in those with binge-eating disorder (BED) is limited. Given BED's high prevalence and low levels of treatment uptake, further eTherapy evaluation is needed to broaden access to effective, evidence-based treatment options. The aim of this study was to investigate the acceptability, feasibility, and preliminary efficacy of a supported eTherapy for those with BED or subthreshold BED, and to examine symptom change across the duration of therapy. Method Nineteen women with BED completed a supported, 10-session Cognitive Behavioural Therapy-based eTherapy in an uncontrolled, pre-post, and 3 months follow up intervention study. Key outcomes were assessed by the Eating Disorder Examination Questionnaire (EDE-Q): objective binge episode (OBE) frequency and ED psychopathology. Feasibility was evaluated via program adherence and dropout, whilst acceptability was assessed through participant feedback post-treatment. Weekly symptom change (ED psychopathology) during treatment was assessed by the Eating Disorder Examination - Questionnaire Short (EDE-QS). Results Generalised estimating equations showed statistically and clinically significant reductions in OBEs and ED psychopathology (large effects) post-treatment, with these decreases maintained at follow up. Across weekly assessment, a marked slowing in the rate of change in ED psychopathology was observed after four sessions of the program. Program feasibility was high (i.e., 84% of content completed), as was program acceptability (i.e., 93% of participants expressed high levels of satisfaction). Discussion These results support the acceptability, feasibility, and preliminary efficacy of a supported eTherapy program for those with BED and suggest the variability of symptom change across the duration of therapy. Future research should further investigate findings in an adequately powered randomised controlled trial.

Abstract
INTRODUCTION Binge-eating disorder (BED) is a complex and disabling eating disorder (ED) associated with considerable burden and impairments in quality of life and physical/mental health. It has been recognized as a formal ED category since 2013, however BED is still underdetected and undertreated. AREAS COVERED This review summarizes the advances in the understanding of the pathophysiology of BED as well as the evidence on the efficacy of the existing treatments. The authors searched Scopus, PubMed, ClinicalTrials.Gov, and ANZCTR with terms including 'assessment' OR 'treatment' OR 'diagnosis' OR 'mechanisms' AND 'binge eating' OR 'binge-eating disorder' for manuscripts published between January 2013 and April 2023. EXPERT OPINION Most of the trials on treatments of BED have been in people of high weight with weight loss as an outcome. Nevertheless, less is known about the treatment of this condition in people with body mass index (BMI) within the normal range where weight stabilization may be a more appropriate goal. Moreover, there is a need for an enhanced appreciation of the role of combination treatment to improve overall outcomes. Also, there are important opportunities for future research in understanding the mechanisms of action and effectiveness of BED treatments.

Effects of Participant's Choice of Different Digital Interventions on Outcomes for Binge-Spectrum Eating Disorders: A Pilot Doubly Randomized Preference Trial. Behav Ther 2023; 54:303-314.

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
Objective Online medical consultation (OMC) is increasingly used in China, but there have been few in-depth studies of consultation arrangements and fee structures of online doctors in China. This research assessed the consultation arrangements and fee structure of OMC in China by undertaking a case study of obesity doctors from four representative OMC platforms. Methods Detailed information, including fees, waiting time and doctor information, was collected from four obesity OMC platforms and analyzed using descriptive statistical analysis. Results The obesity OMC platforms in China shared similarities in the use of big data and artificial intelligence (AI) but differed across service access, specific consultation arrangements and fees. Big data search and AI response technologies were used by most platforms to match users with doctors and reduce doctors' pressure. The descriptive statistical analysis showed that the higher the rank of the online doctor, the higher the online fee and the longer the wait time. Through a comparison with offline hospitals, we found online doctors' fees exceeded offline hospital doctors' fees by up to 90%. Conclusions OMC platforms can gain competitive advantages over offline medical institutions through the following measures: make fuller use of big data and AI technologies to provide users with longer duration, lower cost and more efficient consultation services; provide better user experience than offline medical institutions; use big data and fee advantages to screen doctors to match users' consultation needs instead of screening by the rank of doctors only; and cooperate with commercial insurance providers to provide innovative health care packages.

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

Abstract
OBJECTIVE For those with binge-eating disorder (BED), access to evidence-based, face-to-face treatment is often constrained by clinician availability and high treatment costs. Emerging evidence suggests online therapy (eTherapy) may navigate these barriers and reduce binge-eating symptomatology; however, less evaluation has been done in those with BED, particularly with briefer programs targeting early change. This study investigated the feasibility and potential efficacy of a brief, supported eTherapy in those with BED or subthreshold BED. METHOD Participants were 19 women with BED who completed a four-session eTherapy. This was a single-arm, pre-post intervention study, with participants completing weekly content and attending telehealth sessions. Key outcomes were assessed by the Eating Disorder Examination Questionnaire-Short (EDE-QS): objective binge episode days, loss of control over eating days, and eating disorder (ED) psychopathology via a total EDE-QS score. RESULTS Generalized and linear mixed models showed significantly reduced loss of control over eating days and ED psychopathology. Program feasibility was high, with strong program adherence and a below average attrition rate. DISCUSSION Pilot results support the feasibility and potential efficacy of a brief, behavioral-focused eTherapy program in reducing ED pathology in those with BED. Future research should further investigate findings in an adequately powered randomized controlled trial. PUBLIC SIGNIFICANCE This study suggests that a brief, behavioral-focused online therapy, guided by non-expert clinicians, can be successfully administered to those with binge-eating disorder (BED) and may be efficacious at reducing eating disorder and other related symptomatology. Brief eTherapies that are effective, accessible, and rapidly available may facilitate earlier intervention in illness and improve treatment outcomes for individuals who experience this common and distressing disorder.

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.

Randomized Controlled Comparison of an Internet-Based Intervention for Eating Disorder Symptoms With and Without Interactive Functionality. Behav Ther 2022; 53:508-520. [PMID: 35473653 DOI: 10.1016/j.beth.2021.12.001] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 12/05/2021] [Accepted: 12/06/2021] [Indexed: 12/13/2022]
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
IMPORTANCE Eating disorders are associated with adverse health and social outcomes. OBJECTIVE To review the evidence on screening for eating disorders in adolescents and adults to inform the US Preventive Services Task Force. DATA SOURCES MEDLINE, Cochrane Library, PsycINFO, and trial registries through December 19, 2020; surveillance through January 1, 2022. STUDY SELECTION English-language studies of screening test accuracy, randomized clinical trials (RCTs) of screening or interventions for eating disorders in populations with screen-detected or previously untreated eating disorders (trials limited to populations who are underweight were ineligible). DATA EXTRACTION AND SYNTHESIS Dual review of abstracts, full-text articles, and study quality. Meta-analysis of test accuracy studies and intervention trials. MAIN OUTCOMES AND MEASURES Test accuracy, eating disorder symptom severity, quality of life, depression, and harms. RESULTS Fifty-seven studies were included (N = 10 773); 3 (n = 1073) limited to adolescents (mean or median age, 14-15 years). No study directly evaluated the benefits and harms of screening. Seventeen studies (n = 6804) evaluated screening test accuracy. The SCOFF questionnaire (cut point ≥2) had a pooled sensitivity of 84% (95% CI, 74% to 90%) and pooled specificity of 80% (95% CI, 65% to 89%) in adults (10 studies, n = 3684). Forty RCTs (n = 3969) evaluated interventions for eating disorders; none enrolled a screen-detected population. Lisdexamfetamine for binge eating disorder (4 RCTs; n = 900) was associated with larger reductions in eating disorder symptom severity on the Yale-Brown Obsessive Compulsive Scale modified for binge eating (YBOCS-BE) than placebo (pooled mean difference, -5.75 [95% CI, -8.32 to -3.17]). Two RCTs (n = 465) of topiramate for binge eating disorder found larger reductions in YBOCS-BE scores associated with topiramate than placebo, from -6.40 (95% CI, -8.16 to -4.64) to -2.55 (95% CI, -4.22 to -0.88). Nine pharmacotherapy trials (n = 2006) reported on harms. Compared with placebo, lisdexamfetamine was associated with higher rates of dry mouth, headache, and insomnia, and topiramate was associated with higher rates of paresthesia, taste perversion, confusion, and concentration difficulty. Twenty-four trials (n = 1644) assessed psychological interventions. Guided self-help for binge eating disorder improved eating disorder symptom severity more than control (pooled standardized mean difference, -0.96 [95% CI, -1.26 to -0.67]) (5 studies, n = 391). Evidence on other interventions was limited. CONCLUSIONS AND RELEVANCE No studies directly assessed the benefits and harms of screening. The SCOFF questionnaire had adequate accuracy for detecting eating disorders among adults. No treatment trials enrolled screen-detected populations; guided self-help, lisdexamfetamine, and topiramate were effective for reducing eating disorder symptom severity among referred populations with binge eating disorder, but pharmacotherapies were also associated with harms.

Abstract
Although evidence demonstrated efficacy of cognitive-behavioral therapy (CBT) in adolescents with binge-eating disorder (BED), treatment response is heterogeneous. This study uniquely examined baseline predictors of symptom trajectories in N = 73 adolescents (12-20 years) with an age-adapted diagnosis of BED (i.e., based on objective and subjective binge-eating episodes). Based on evidence from adult BED, dietary restraint, overvaluation of weight/shape, and depressive symptoms were used to predict changes in abstinence from binge eating and eating disorder psychopathology after 4 months of individual, face-to-face CBT using growth models. Longitudinal trajectories of abstinence from objective and subjective binge eating and global eating disorder psychopathology assessed via the Eating Disorder Examination were modeled for five time points (pre- and posttreatment, 6-, 12-, and 24-month follow-up). Beyond significant, positive effects for time, no significant predictors for abstinence from binge eating emerged. In addition to significant decreases in eating disorder psychopathology over time, higher pretreatment dietary restraint and overvaluation of weight/shape significantly predicted greater decreases in eating disorder psychopathology over time. Consistent with research in adult BED, adolescents with higher than lower eating disorder-specific psychopathology especially benefit from CBT indicating that restrained eating and overvaluation of weight/shape may be BED-specific prognostic characteristic across developmental stages. Future predictor studies with an additional focus on potential age-specific predictors, such as family factors, and within-treatment processes may be critical in further evaluating treatment-related symptom trajectories in adolescent BED.

Abstract
OBJECTIVE Online treatment for binge eating disorder (BED) is an easily available option for treatment compared to most standard treatment procedures. However, little is known about how motivation types characterize this population and how these impact treatment adherence and effect in an online setting. Therefore, we aimed to investigate a sample of written motivation statements from BED patients, to learn more about how treatment and online treatment in particular, presents in this population. METHODS Using self-determination theory in a mixed methods context, we investigated which types of motivation were prevalent in our sample, how this was connected with patient sentiment, and how these constructs influence treatment and adherence. RESULTS Contrary to what most current literature suggests, we found that in our sample (n = 148), motivation type was not connected with treatment outcome. We did find a strong association between sentiment scores and motivation types, indicating the model is apt at detecting effects. We found that when comparing an adult and young adult population, they did not differ in motivation type and the treatment was equally effective in young adults and adults. In the sentiment scores there was a difference between sentiment score and adherence in the young adult group, as the more positive the young adults were, the less likely they were to complete the program. DISCUSSION Because motivation type does not influence online treatment to the same degree as it would in face-to-face treatment it indicates that the typical barriers to treatment may be less crucial in an online setting. This should be considered during intake; as less motivated patients may be able to adhere better to online treatment, because the latter imposes fewer barriers of the kind that only strong motivation can overcome. The fact that motivation type and sentiment score of the written texts are strongly associated, indicate a potential for automated models to detect motivation based on sentiment.

Abstract
Purpose
Eating disorders (EDs) is a major health condition affecting 9% of the global population and 10% of those with EDs lost their lives as a result. Text-based telehealth interventions (TTIs) seem to provide a low-cost and convenient treatment option; however, the evidence is scarce. This study aimed to synthesize evidence relating to the use of TTIs for the management of EDs.
Design/methodology/approach
Five databases were searched published between January 2020 and May 2019. The authors used keywords relating to telehealth and EDs. The authors used Joanna Briggs Institute's (JBI's) critical appraisal instrument to assess the methodology quality of included studies.
Findings
Fifteen studies were included in this mix-method systematic review and assessed for methodology quality. Email, web-based texting, text-messaging and online chat room were used as mode for deliver healthcare for patients with EDs. In the treatment phase, all studies (nine studies; n = 860 participants) showed effectiveness (for RCTs) and usefulness (for non-RCT studies). In the aftercare phase (six studies; n = 364 participants), the results regarding the effectiveness of TTIs were mixed. Two studies showed effectiveness whilst four studies did not find statistically significant change of ED outcomes.
Research limitations/implications
The qualities of these studies varied; firstly, 66% (n = 10) of the studies were non-randomized studies (e.g. single-arm trial, case report) with small samples. Moreover, one-fourth (n = 4) of the studies did not use validated instruments or indicate the instrument. Also, half (n = 7) of the studies used TTIs as adjunct to face-to-face treatment or bigger online treatment, it is hard to make conclusion that the changes were due to TTIs' effect. In addition, follow-up rate is not satisfactory, thus results should be interpreted cautiously.
Practical implications
TTIs seem to be promising for management of EDs, particularly in the treatment phase. This provides an important treatment option for health practitioners and people with EDs as an alternative or in adjunct with face-to-face services.
Originality/value
This is the first review to synthesis the use of TTIs for ED management.

Abstract
Background There has been a recent rise in the use of eHealth treatments for a variety of psychological disorders, including eating disorders. Objective This meta-analysis of randomized controlled trials is the first to evaluate the efficacy of eHealth interventions specifically for the treatment of binge eating disorder (characterized by compulsive overconsumption of food, in a relatively short period, and without compensatory behaviors such as purging or fasting). Methods A search on the electronic databases PubMed, Web of Science, Embase, MEDLINE, and CINAHL was conducted for randomized controlled trials that compared the efficacy of eHealth treatment interventions with waitlist controls. Results From the databases searched, 3 studies (298 participants in total) met the inclusion criteria. All interventions were forms of internet-based guided cognitive behavioral therapy. The results of the analysis demonstrated that when compared with waitlist controls, individuals enrolled in eHealth interventions experienced a reduction in objective binge episodes (standardized mean difference [SMD] −0.77, 95% CI −1.38 to −0.16) and eating disorder psychopathology (SMD −0.71, 95% CI −1.20 to −0.22), which included shape (SMD −0.61, 95% CI −1.01 to −0.22) and weight concerns (SMD −0.91, 95% CI −1.33 to −0.48). There was no significant difference in BMI between the eHealth interventions and controls (SMD −0.01, 95% CI −0.40 to 0.39). Conclusions These findings provide promising results for the use of internet-based cognitive behavioral therapy for binge eating disorder treatment and support the need for future research to explore the efficacy of these eHealth interventions.

Abstract
Research findings strongly suggest that cognitive behavioral therapy for the eating disorders (CBT-ED) is more effective than other treatments for bulimia nervosa (BN) and for binge eating disorder (BED), although interpersonal psychotherapy appears to be equally effective for BED. Evidence for the effectiveness of CBT-ED for the persistent (adult) form of anorexia nervosa (AN) is insufficient at present and is essentially absent for AN in adolescents except for some evidence from uncontrolled trials. This article begins with an overview of the early studies in the development of CBT-ED that showed a similar effectiveness of other symptom-focused psychotherapies-a finding that was neglected at the time. Later developments are then considered, including comparisons of CBT-ED with other psychotherapies, efforts to develop Internet-based training and treatment, and electronic applications for treatment. Finally, implications of the findings for future short- and long-term research and for clinical practice are considered.

Abstract
OBJECTIVE Binge-eating disorder (BED) is characterized by recurrent episodes of binge eating, accompanied by a lack of control and feelings of shame. Online intervention is a promising, accessible treatment approach for BED. In the current study, we compared completers with noncompleters in a 10-session guided internet-based treatment program (iBED) based on cognitive behavioral therapy. METHODS Adults (N = 75) with mild to moderate BED participated in iBED with weekly written support from psychologists. Participants were compared on the Eating Disorder Examination Questionnaire (EDE-Q), diagnostic criteria for BED (BED-Q), major depression inventory (MDI), quality of life (EQ-5D-5L), body mass index (BMI) and sociodemographic variables. RESULTS Minor differences were observed between completers and noncompleters on depression. No differences were found in BED-symptoms, BMI, and sociodemographic variables. Participants who completed treatment showed large reductions in eating disorder pathology. DISCUSSION More research is needed to determine risk factors for attrition or treatment outcome in internet-based interventions for BED. It is suggested that iBED is an efficient intervention for BED. However, more studies of internet-interventions are needed.

Abstract
OBJECTIVE Long-term effectiveness is a critical aspect of the clinical utility of a treatment; however, a meta-analytic evaluation of psychological and medical treatments for binge-eating disorder (BED), including weight loss treatments, is outstanding. This meta-analysis sought to provide a comprehensive evaluation of the long-term effectiveness in diverse treatments for BED regarding a range of clinically relevant outcomes. METHOD Based on a systematic search up to February 2018, 114 published and unpublished randomized-controlled (RCTs), nonrandomized, and uncontrolled treatment studies, totaling 8,862 individuals with BED (DSM-IV, DSM-5), were identified and analyzed using within-group random-effect modeling. RESULTS Effectiveness (regarding binge-eating episodes and abstinence, eating disorder and general psychopathology) up to 12 months following treatment was demonstrated for psychotherapy, structured self-help treatment, and combined treatment, while the results regarding body weight reduction were inconsistent. These results were confirmed in sensitivity analyses with RCTs on the most common treatments-cognitive-behavioral therapy and self-help treatment based on this approach. Follow-up intervals longer than 12 months were rarely reported, mostly supporting the long-term effectiveness of psychotherapy. Few follow-up data were available for pharmacotherapy, and behavioral and self-help weight loss treatment, while follow-up data were lacking for pharmacological and surgical weight loss treatment. Study quality varied widely. DISCUSSION This comprehensive meta-analysis demonstrated the medium-term effectiveness of psychotherapy, structured self-help treatment, and combined treatment for patients with BED, and supported the long-term effectiveness of psychotherapy. The results were derived from uncontrolled comparisons over time. Further long-term high quality research on psychological and medical treatments for BED is required.

Abstract
BACKGROUND In a world of technological advancements, electronic devices and services seem to be a promising way to increase patients' engagement in treatment and to help manage their symptoms. Here, we identified and analyzed the current evidence of RCTs to evaluate the effectiveness and acceptability of e-health interventions in the eating disorder (ED) field. METHODS We screened an initial cluster of 581 papers. In the end, 12 RCTs in clinical ED cohorts were included. RESULTS Some studies were conceived as stand-alone interventions, while others were presented as add-ons to ED-specific treatments. Studies varied in the type of EDs under investigation and in the e-health intervention applied (with vs. without therapist support vs. blended interventions; smartphone- vs. web-based). Only four studies reported explicit acceptability measures. Out of those, two reported high acceptability, one reported low acceptability, and one reported no significant difference in acceptability between groups. Four studies reported higher effectiveness of the e-health intervention compared to the control condition, e.g., reduction in maladaptive eating behaviors. Regarding control groups, three used a wait list design and nine had another kind of intervention (e.g., face-to-face CBT, or treatment as usual) as control. DISCUSSION So far, the evidence for acceptability and effectiveness of e-health interventions in EDs is very limited. There is also a lack of studies in older patients, adolescents, men, sexual and ethnic minorities. Shame/stigma is discussed in the context of e-health interventions for EDs. It remains unclear how severity of EDs affects the effectiveness of e-health interventions, how patients can channel the knowledge they acquire from e-health interventions into their actual behaviors, and how such interventions can better fit the needs of the individual patient to increase acceptability and effectiveness.

Abstract
Background: There has been increasing interest in using videoconferencing in health care, but limited research was conducted in Binge Eating Disorder (BED) patients. This 3-month pilot study aimed to assess the feasibility, acceptability, and preliminary efficacy of a videoconferencing (VC)-based treatment program in overweight and obese females with BED. Methods: Eighteen participants, aged 20-73, were diagnosed and randomized into either a face-to-face (F2F) group or a VC-based group. In the F2F group, participants received 12 one-on-one weekly counseling sessions from a Licensed Mental Health Counselor and Registered Dietitian Nutritionist. In the VC group, participants received the same counseling through an online telemedicine software. Measured outcomes include retention, adherence to treatment, and attitudinal and behavioral changes of participants. Results: In the end of study, of the 9 participants randomized into each group, 8 (88.9%) F2F participants and 4 (44.4%) VC participants completed the study. On average, F2F finishers attended 94.8% of sessions and completed 66.2% of dietary diaries. VC finishers attended 95.8% of sessions and completed 55.4% of diaries. No changes in weight and binge eating episode were observed in either group. F2F finishers had significant improvement on uncontrolled eating (p = 0.01), emotional eating (p = 0.004), food addiction diagnosis (p = 0.04), loss of control (p = 0.04), and clinical significance (p = 0.04). VC finishers observed significant improvements in eating disorder examination shape concern (p = 0.03) and global score (p = 0.03). Conclusion: VC-based treatment program is feasible and could be effective for BED patients. Long-term large-scale randomized clinical trials are warranted to further assess the efficacy.

Abstract
OBJECTIVE Despite the existence of reviews which document the effectiveness of online therapies, there is little consensus regarding the exact components of online treatment delivery that are most effective in maintaining user engagement and reducing eating disorder (ED) symptomology. The current review and meta-analysis aimed to determine which components of web-based, ED self-help interventions are associated with lower attrition and improved therapeutic outcome. METHOD A systematic search of electronic databases (PsycINFO, Medline, Web of Science, Scopus) was conducted for published studies of web-based interventions for EDs and a meta-analysis of the final included studies was performed. Each intervention was coded across four dimensions, including the multimedia channels employed (e.g., text, audio, videos), degree of user interactivity (e.g., online self-monitoring, skills exercises), level of automated feedback (e.g., reminders, personalized feedback), and technological device through which the program was accessed (e.g., smartphone, computer). RESULTS A final 23 papers were included. The results of meta-regressions indicated that higher scores on the multimedia subscale were associated with greater ED symptom improvement in treatment groups. Conversely, a higher degree of feedback in the treatment group was associated with a group difference in ED psychopathology favoring the control group. Other intervention components were not associated with treatment outcome or dropout. DISCUSSION The results are discussed in relation to limitations of the scale used to quantify digital intervention features, as well as the limited diversity and technological sophistication of available ED digital interventions. Such findings indicate the importance of understanding the digital components, which differentiate online therapeutic programs.

Abstract
OBJECTIVE Standardized effect sizes reported in previous meta-analyses of binge-eating disorder (BED) treatment are sometimes difficult to interpret and are criticized for not being a useful indicator of the clinical importance of a treatment. Abstinence from binge eating is a clinically relevant component of a definition of a successful treatment outcome. This meta-analysis estimated the prevalence of patients with BED who achieved binge eating abstinence following psychological or behavioral treatments. METHOD This meta-analysis included 39 randomized controlled trials, with 65 treatment conditions and 2,349 patients. Most conditions comprised cognitive-behavioral therapy (n = 40). Pooled event rates were calculated at posttreatment and follow-up using random effects models. RESULTS The total weighted percentage of treatment-completers who achieved abstinence at posttreatment was 50.9% (95% CI = 43.9, 57.8); this estimate was almost identical at follow-up (50.3%; 95% CI = 43.6, 56.9). The total weighted percentage of patients who achieved abstinence at posttreatment in the intention-to-treat analysis (all randomized patients) was 45.1% (95% CI =40.7, 49.5), and at follow-up it was 42.3% (95% CI =37.5, 47.2). Interpersonal psychotherapy (IPT) produced the highest abstinence rates. Clinician-led group treatments produced significantly higher posttreatment (but not follow-up) abstinence estimates than guided self-help treatments. Neither timeframe for achieving abstinence, assessment type (interview/questionnaire), number of treatment sessions, patient demographics, nor trial quality, moderated the abstinence estimates. DISCUSSION The present findings demonstrate that 50% of patients with BED do not fully respond to treatment. Continued efforts toward improving eating disorder treatments are needed.

Abstract
The evolution of cognitive-behavioral therapy (CBT) for the treatment of bulimic disorders is described in this review. The impacts of successive attempts to enhance CBT such as the addition of exposure and response prevention; the development of enhanced CBT; and broadening the treatment from bulimia nervosa to binge eating disorder are considered. In addition to developing advanced forms of CBT, shortening treatment to guided self-help was the first step in broadening access to treatment. The use of technology such as computer-based therapy and more recently the Internet, promises further broadening of access to self-help and to therapist guided treatment. Controlled studies in this area are reviewed, and the balance of risks and benefits that accompany the use of technology and lessened therapist input are considered. Looking into the future, more sophisticated forms of treatment delivered as mobile applications ("apps") may lead to more personalized and efficacious treatments for bulimic disorders, thus enhancing the delivery of treatments for eating disorders.

Abstract
Remarkable progress has been made in developing psychosocial interventions for eating disorders and other mental disorders. Two priorities in providing treatment consist of addressing the research-practice gap and the treatment gap. The research-practice gap pertains to the dissemination of evidence-based treatments from controlled settings to routine clinical care. Closing the gap between what is known about effective treatment and what is actually provided to patients who receive care is crucial in improving mental health care, particularly for conditions such as eating disorders. The treatment gap pertains to extending treatments in ways that will reach the large number of people in need of clinical care who currently receive nothing. Currently, in the United States (and worldwide), the vast majority of individuals in need of mental health services for eating disorders and other mental health problems do not receive treatment. This article discusses the approaches required to better ensure: (1) that more people who are receiving treatment obtain high-quality, evidence-based care, using such strategies as train-the-trainer, web-centered training, best-buy interventions, electronic support tools, higher-level support and policy; and (2) that a higher proportion of those who are currently underserved receive treatment, using such strategies as task shifting and disruptive innovations, including treatment delivery via telemedicine, the Internet, and mobile apps.
