Harnessing the power of technology for the treatment and prevention of eating disorders

Internet-based cognitive behaviour therapy for the prevention, treatment and relapse prevention of eating disorders: A systematic review and meta-analysis

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.

Days between sessions predict attrition in text-based internet intervention of Binge Eating Disorder

BACKGROUND

The number of days between treatment sessions is often overlooked as a predictor of attrition in psychotherapy. In text-based Internet interventions, days between sessions may be a simple yet powerful predictor of attrition.

OBJECTIVE

We hypothesized that a larger number of days between sessions increased the likelihood of attrition among participants with Binge Eating Disorder (BED) in a 12-session Internet-based cognitive behavioral therapy (iCBT) program. Participants could work on the sessions whenever convenient for them and received written support from a psychologist.

MATERIAL AND METHODS

We compared 201 adult participants with mild to moderate BED (85 non-completers and 116 completers) on the number of days between sessions to predict attrition rates.

RESULTS

Mixed model binomial logistic regression showed that non-completers spent significantly more days between sessions across the first four treatment sessions (1-4) when controlling for age, gender, and intake measures of BMI, BED, overall health status (EQ VAS), and depression symptoms (MDI) (OR = 1.042, p < .001). Age (OR = 0.976, p < .001) and EQ VAS (OR = 0.984, p < .001) were also significant. The risk of attrition increased by 4.2 % for each additional day participants spent completing a session.A receiver operating characteristic (ROC) curve analysis showed that classification accuracy increased across sessions from 61.1 % in session 1 and 65.7 % in session 2 to 68.8 % in session 3 and 73.2 % in session 4. The optimal cut-off point in session 4 was 17.5 days, which detected 60.4 % of non-completers (sensitivity) and 78.4 % of completers (specificity).An exploratory repeated measures of ANOVA of days between sessions showed a significant within-subjects effect, where both non-completers and completers spent more days between sessions as they progressed from sessions 1 through 4 (F = 20.54, df = 3, p < .001). There was no interaction effect, suggesting that the increase in slope did not differ between non-completers and completers.

CONCLUSIONS

Participants spending more days between sessions are at increased risk of dropping out of treatment. This may have important implications for identifying measures to reduce attrition, e.g., intensifying interventions through automated reminders or therapist messages. Our findings may have important transdiagnostic implications for text-based Internet interventions. Further studies should investigate the predictive value of days between sessions in other diagnoses.

Accessibility of Psychological Treatments for Bulimia Nervosa: A Review of Efficacy and Engagement in Online Self-Help Treatments

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.

Cognitive training via a mobile application to reduce some forms of body dissatisfaction in young females at high-risk for body image disorders: A randomized controlled trial

Body dissatisfaction has been related to Body Image Disorders (BIDs) such as Eating Disorders (EDs) and Body Dysmorphic Disorder (BDD). This study investigates the efficacy of a mHealth app in reducing body dissatisfaction, BDD/ED symptoms and related features. Ninety-five women who were identified as high-risk of developing BIDs (using the Structured Clinical Interview for DSM-5) were randomized into: immediate-use App (iApp group; n = 47) and delayed-use App (dApp group; n = 48). The iApp group started using the app at baseline for 16 days (T1). The dApp group started using the app at T1 for 16 days. Participants completed questionnaires at baseline (T0), 16 days from baseline (T1), and 32 days from baseline (T2). Repeated measure Multivariate Analysis of Variance (MANOVA) showed Group (iApp vs. dApp) × Time (T0 vs. T1) interactions indicating decrease in BDD symptoms and body dissatisfaction related to EDs in the iApp group at T1. The Reliable Change Index indicated changes on extreme body dissatisfaction/BDD symptoms for 34.74% of participants. Although preliminary, these findings highlight that a mHeatlh app might reduce BDD symptoms and body dissatisfaction related to EDs in women at high-risk for BIDs. Effects on ED symptoms and associated features seem more limited.

Retention, engagement, and binge-eating outcomes: Evaluating feasibility of the Binge-Eating Genetics Initiative study

OBJECTIVE

Using preliminary data from the Binge-Eating Genetics Initiative (BEGIN), we evaluated the feasibility of delivering an eating disorder digital app, Recovery Record, through smartphone and wearable technology for individuals with binge-type eating disorders.

METHODS

Participants (n = 170; 96% female) between 18 and 45 years old with lived experience of binge-eating disorder or bulimia nervosa and current binge-eating episodes were recruited through the Recovery Record app. They were randomized into a Watch (first-generation Apple Watch + iPhone) or iPhone group; they engaged with the app over 30 days and completed baseline and endpoint surveys. Retention, engagement, and associations between severity of illness and engagement were evaluated.

RESULTS

Significantly more participants in the Watch group completed the study (p = .045); this group had greater engagement than the iPhone group (p's < .05; pseudo-R2 McFadden effect size = .01-.34). Overall, binge-eating episodes, reported for the previous 28 days, were significantly reduced from baseline (mean = 12.3) to endpoint (mean = 6.4): most participants in the Watch (60%) and iPhone (66%) groups reported reduced binge-eating episodes from baseline to endpoint. There were no significant group differences across measures of binge eating. In the Watch group, participants with fewer episodes of binge eating at baseline were more engaged (p's < .05; pseudo-R2 McFadden  = .01-.02). Engagement did not significantly predict binge eating at endpoint nor change in binge-eating episodes from baseline to endpoint for both the Watch and iPhone groups.

DISCUSSION

Using wearable technology alongside iPhones to deliver an eating disorder app may improve study completion and app engagement compared with using iPhones alone.

Digital Health Interventions for Delivery of Mental Health Care: Systematic and Comprehensive Meta-Review

BACKGROUND

The COVID-19 pandemic has shifted mental health care delivery to digital platforms, videoconferencing, and other mobile communications. However, existing reviews of digital health interventions are narrow in scope and focus on a limited number of mental health conditions.

OBJECTIVE

To address this gap, we conducted a comprehensive systematic meta-review of the literature to assess the state of digital health interventions for the treatment of mental health conditions.

METHODS

We searched MEDLINE for secondary literature published between 2010 and 2021 on the use, efficacy, and appropriateness of digital health interventions for the delivery of mental health care.

RESULTS

Of the 3022 records identified, 466 proceeded to full-text review and 304 met the criteria for inclusion in this study. A majority (52%) of research involved the treatment of substance use disorders, 29% focused on mood, anxiety, and traumatic stress disorders, and >5% for each remaining mental health conditions. Synchronous and asynchronous communication, computerized therapy, and cognitive training appear to be effective but require further examination in understudied mental health conditions. Similarly, virtual reality, mobile apps, social media platforms, and web-based forums are novel technologies that have the potential to improve mental health but require higher quality evidence.

CONCLUSIONS

Digital health interventions offer promise in the treatment of mental health conditions. In the context of the COVID-19 pandemic, digital health interventions provide a safer alternative to face-to-face treatment. However, further research on the applications of digital interventions in understudied mental health conditions is needed. Additionally, evidence is needed on the effectiveness and appropriateness of digital health tools for patients who are marginalized and may lack access to digital health interventions.

Text based internet intervention of Binge Eating Disorder (BED): Words per message is associated with treatment adherence

BACKGROUND

Some evidence suggests that in internet-based cognitive behavioral therapy (iCBT) the likelihood of adherence is increased when patients write longer messages to the therapist in the program. This association has not previously been investigated in iCBT for Binge Eating Disorder (BED).

OBJECTIVE

In this study, we hypothesized that the number of words written by patients with mild to moderate BED was associated with increased likelihood of treatment completion in a text-based iCBT program.

MATERIAL AND METHODS

We compared 143 BED patients (92 completers and 51 non-completers) on the number of messages and words written to their therapist during the treatment.

RESULTS

Completers wrote significantly more words per message (words/message) than non-completers. The results remained significant after controlling for gender, age, educational level, marital status, children, source of income and intake measures of BED, BMI and depression symptoms (Wald = 14.48, p < .001). The odds ratio of completion increased by 1.5% for each additional word patients wrote per message (OR = 1.015). The model showed a 72.4% classification accuracy, and an optimal cut-off point of 68.99 words/message for differentiating completers and non-completers. The model accurately identified 80.9% of completers (sensitivity) and 54.9% of non-completers (specificity).

CONCLUSIONS

The number of words/message patients write may have important implications for ascertaining likelihood of adherence and improving adherence rates. From a clinical perspective, therapists should encourage patients to use the option of writing messages to the therapist. Words/message may prove to be a transdiagnostic predictor of treatment adherence in text based iCBT.

Recruitment, adherence and attrition challenges in internet-based indicated prevention programs for eating disorders: lessons learned from a randomised controlled trial of ProYouth OZ

BACKGROUND

Growing evidence supports the effectiveness of Internet-based prevention programs for eating disorders, but the adjunctive benefit of synchronous peer support has yet to be investigated. In the current study, a randomised controlled trial was conducted to evaluate the effectiveness of an indicated Internet-based prevention program (ProYouth OZ) with and without peer-to-peer support in reducing disordered eating behaviours and attitudes.

METHOD

Fifty young adults (18-25 years) with eating disorder symptoms were randomised to one of three study conditions: (1) ProYouth OZ (without peer-to-peer support), (2) ProYouth OZ Peers (with peer-to-peer support), and (3) a waitlist control group. Outcomes were assessed at three different time points. Eating disorder symptoms (primary outcome) were measured with the Eating Disorder Examination Questionnaire.

RESULTS

Of 415 screened participants, 73 (17.6%) were eligible and 213 (51.3%) excluded due to severe eating disorder symptoms. Fifteen participants (30%) completed the post-intervention survey. Of the two intervention groups, 20.6% failed to access any component of the program. Of 17 ProYouth OZ Peers participants, 58.8% attended at least one chat session, 20% attended 2-5 sessions, and 11.8% attended all six sessions. Due to limited outcome data, it was not possible to statistically examine between-group differences in outcomes. Visual inspection of individual profiles revealed that both ProYouth OZ Peers participants who completed the post-intervention survey showed a decrease in disordered eating compared with only one of the six completers in ProYouth OZ.

CONCLUSION

Findings highlight the challenges of trialling Internet-based eating disorder prevention programs in the community. The study identified a large group of emerging adults with eating disorders who were interested in an Internet-based program, suggesting a high level of unmet need. Future research on synchronous peer-to-peer support in Internet-based prevention for eating disorders is warranted. Further studies are required to identify optimal strategies for reaching this population (e.g., online vs. offline) and evaluating the effectiveness of a range of strategies for promoting engagement. Finally, there is an urgent need to develop innovative widely accessible interventions for individuals who experience clinically relevant eating disorder symptomatology but may not be ready or able to seek professional face-to-face treatment.

Evaluation of the Effects of Telepsychotherapy in the Treatment and Prevention of Eating Disorders in Adolescents

According to the WHO definition, "telemedicine is the provision of health services, where distance is a critical factor, by all health professionals who use information and communication technologies for the exchange of valid information for the diagnosis, treatment and prevention of diseases, research and evaluation, and for the continuous training of health professionals, all in the interest of advancing the health of individuals and their communities". The purpose of our review work is specifically to investigate the effects of telemedicine in the treatment and prevention of eating disorders in adolescents. From June 2021 to (September 2021) in the databases of the Web of Science, EMBASE, PsycINFO and CINHAL, using search terms such as telehealth, eating disorder, adolescents, Internet/online treatments CBT and FB-T, anorexia nervosa, bulimia nervosa and binge eating disorder. The articles resulting from the search phases in the databases listed above produced a total of 176 items. Once the procedures for selecting the works were completed, only four studies were included in the review. Modern e-health psychological approaches in the treatment of eating disorders provide potential bases of continuous assistance that are decidedly less burdensome in the costs of territorial services in the case that they are not identified as necessary.

Efficacy of post-inpatient aftercare treatments for anorexia nervosa: a systematic review of randomized controlled trials

BACKGROUND

Early relapse after inpatient treatment is a serious problem in the management of anorexia nervosa (AN). Specialized aftercare interventions have the potential to bridge the gap between inpatient and outpatient care, to prevent relapse and to improve the long-term outcome for patients with AN.

METHODS

Following the guidelines of the PRISMA statement, we conducted a systematic review, synthesizing the evidence from randomized-controlled trials (RCTs) investigating the efficacy of post-inpatient aftercare treatments for AN.

RESULTS

Our search resulted in seven RCTs and three registered ongoing trials. Pharmacotherapy and low-threshold guided self-help have limited uptake and high dropout. Novel mobile guided self-help approaches seem promising due to high patient satisfaction, but their efficacy has yet to be investigated in larger trials. Cognitive-behavior psychotherapy may be beneficial in delaying relapse, but evidence is based on a single study.

CONCLUSION

Only a limited number of RCTs investigating aftercare interventions for patients with AN is available. There is no clear evidence favoring any one specific approach for post-inpatient aftercare in adult patients with AN. The field faces many challenges which generally affect intervention research in AN. A specific issue is how to increase uptake of and reduce dropout from aftercare interventions. This calls for better tailoring of interventions to patient needs and the integration of patient perspectives into treatment. Intensified research and care efforts are needed to address the problem of recurrent relapse after intensive inpatient treatment for AN and to eventually improve prognosis for this eating disorder.

Supported online cognitive behavioural therapy for bulimia nervosa: a study protocol of a randomised controlled trial

BACKGROUND

Despite the availability of effective treatments for bulimia nervosa (BN), a number of barriers to accessibility exist. Examples include access to trained clinicians, the expense of treatment, geographical limitations, and personal limitations such as stigma regarding help seeking. Self-help interventions, delivered via a digital platform, have the potential to overcome treatment gaps by providing patients with standardised, evidence-based treatments that are easily accessible, cost-effective, and require minimal clinician support. Equally, it is important to examine the shortcomings of digital interventions when compared to traditional to face-to-face delivery (e.g., high dropout rates) in order to maximise the therapeutic effectiveness of online, self-help interventions.

METHODS

A three-arm, multisite randomised controlled trial will be conducted in Australia examining the effectiveness and cost-effectiveness of a newly developed online self-help intervention, Binge Eating eTherapy (BEeT), in a sample of patients with full or sub-threshold BN. The BEeT program consists of 10, multimedia sessions delivering the core components of cognitive behaviour therapy. Eligible participants will be randomised to one of three groups: independent completion of BEeT as a purely self-help program, completion of BEeT alongside clinician support (in the form of weekly telemedicine sessions), or waitlist control. Assessments will take place at baseline, weekly, post-intervention, and three-month follow up. The primary outcome is frequency of objective binge episodes. Secondary outcomes include frequency of other core eating disorder behavioural symptoms and beliefs, psychological distress, and quality of life. Statistical analyses will examine treatment effectiveness, feasibility, acceptability and cost effectiveness.

DISCUSSION

There is limited capacity within the mental health workforce in Australia to meet the demand of people seeking treatment for eating disorders. This imbalance has only worsened following outbreak of the COVID-19 pandemic. Further research is required into innovative digital modes of treatment delivery with the capacity to service mental health needs in an accessible and affordable manner. Self-help programs may also appeal to individuals who are more reluctant to engage in traditional face-to-face treatment formats. This study will provide rigorous evidence on how to diversify treatment options for individuals with BN, ensuring more people with the illness can access evidence-based treatment. The study has been registered with the Australia New Zealand Clinical Trials Registry (ANZCTR Registration Number: ACTRN12619000123145p). Registered 22 January 2019, https://www.australianclinicaltrials.gov.au/anzctr/trial/ACTRN12619000123145 .

The Impact of the COVID-19 Pandemic on the Number of Adolescents/Young Adults Seeking Eating Disorder-Related Care

PURPOSE

The COVID-19 pandemic has led to the development and worsening of eating disorder (ED) symptoms in adolescents and young adults. In order to examine COVID-19-related trends in ED care-seeking at our institution.

METHODS

We used interrupted time series regression to examine pre- and postpandemic monthly summary data of the following: (1) ED-related inpatient admissions for medical stabilization; (2) ED-related hospital bed-days; (3) completed outpatient ED assessments; and (4) ED outpatient care-related inquiries at a children's hospital in Boston, MA.

RESULTS

Inpatient admissions, hospital bed-days, and outpatient care-related inquiries increased on average over time postpandemic compared to stable volume over time prepandemic (p < .01). Outpatient assessments decreased precipitously initially following COVID-19-related limitations, and rose quickly back to baseline.

CONCLUSION

These results indicate increased need for ED-related care during the pandemic. Bolstering resources to meet the needs of these vulnerable patients is critical as the effects of the pandemic continue to be felt.

A mixed-method systematic review of text-based telehealth interventions in eating disorder management

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.

A systematic review of reach, adoption, implementation and maintenance of Internet-based interventions to prevent eating disorders in adults

BACKGROUND

There is a growing body of research and evidence for the efficacy of Internet-based eating disorder (ED) prevention interventions for adults. However, much less is known about the reach, adoption, implementation and maintenance of these interventions. The RE-AIM (reach, efficacy/effectiveness, adoption, implementation, maintenance) model provides a framework to systematically assess this information.

METHODS

A literature search was conducted in PubMed, Web of Science and PsycINFO for articles published between 2000 and 2019. Additionally, reference lists of the studies included and existing reviews published until the end of 2020 were searched. Sixty original articles describing 54 individual studies fulfilled inclusion criteria. Data were extracted for a total of 43 RE-AIM indicators for each study. Fostering and hindering factors for reach, adoption, implementation and maintenance were assessed qualitatively.

RESULTS

Overall reporting rates were best for the RE-AIM dimensions reach (62.6%), implementation (57.0%) and effectiveness (54.2%), while adoption (24.2%) and maintenance (21.5%) had comparatively low overall reporting rates. Reporting on indicators of internal validity, such as sample size, effects or description of interventions was better than indicators relevant for dissemination and implementation in real-world settings, e.g. characteristics of non-participants, characteristics and representativeness of settings, and data to estimate cost.

CONCLUSIONS

Because most Internet-based ED prevention interventions are provided in a research-funded context, little is known about their public health impact. Better reporting of factors determining external validity is needed to inform dissemination and implementation of these interventions.

A Review on Strategies for Data Collection, Reflection, and Communication in Eating Disorder Apps

Eating disorders (EDs) constitute a mental illness with the highest mortality. Today, mobile health apps provide promising means to ED patients for managing their condition. Apps enable users to monitor their eating habits, thoughts, and feelings, and offer analytic insights for behavior change. However, not only have scholars critiqued the clinical validity of these apps, their underlying design principles are not well understood. Through a review of 34 ED apps, we uncovered 11 different data types ED apps collect, and 9 strategies they employ to support collection and reflection. Drawing upon personal health informatics and visualization frameworks, we found that most apps did not adhere to best practices on what and how data should be collected from and reflected to users, or how data-driven insights should be communicated. Our review offers suggestions for improving the design of ED apps such that they can be useful and meaningful in ED recovery.

Application of three different coaching strategies through a virtual coach for people with emotional eating: a vignette study

BACKGROUND

Around 13% of the world's population suffers from obesity. More than 40% of people with obesity display emotional eating behaviour (eating in response to negative emotions or distress). It is an alternate to more effective coping strategies for negative emotions. Our study explored the opportunities for helping adults with emotional overeating using a virtual coach, aiming to identify preferences for tailored coaching strategies applicable in a personal virtual coach environment. Three different coaching strategies were tested: a validating, a focus-on-change, and a dialectical one - the latter being a synthesis of the first two strategies.

METHODS

A qualitative study used vignettes reflecting the two most relevant situations for people with emotional eating: 1. experiencing negative emotions, with ensuing food cravings; and 2. after losing control to emotional eating, with ensuing feelings of low self-esteem. Applied design: 2 situations × 3 coaching strategies.

PARTICIPANTS

71 adult women (Mage 44.4/years, range 19-70, SD = 12.86) with high scores on the DEBQ-emotional eating scale (Memo 3.65, range 1.69-4.92, SD = .69) with mean BMI 30.1 (range 18-46, SD = 6.53). They were recruited via dieticians' practices, were randomly assigned to the conditions and asked how they would face and react to the presented coaching strategies. Data were transcribed and a thematic analysis was conducted.

RESULTS

Qualitative results showed that participants valued both the validating coaching strategy and the focus-on-change strategy, but indicated that a combination of validation and focus-on-change provides both mental support and practical advice. Data showed that participants differed in their level of awareness of the role that emotions play in their overeating and the need for emotion-regulation skills.

CONCLUSION

The design of the virtual coach should be based on dialectical coaching strategies as preferred by participants with emotional eating behaviour. It should be tailored to the different stages of awareness of their emotions and individual emotion-regulation skills.

COVID-19 Pandemic and Eating Disorders: What Can We Learn About Psychopathology and Treatment? A Systematic Review

PURPOSE OF REVIEW

This systematic review aims to collect evidence regarding the impact of the SarsCov-2 pandemic on people affected by eating disorders (EDs) targeting the following variables: psychopathology changes, mechanisms of vulnerability or resilience, and perception of treatment modifications during the pandemic.

RECENT FINDINGS

Since the beginning of the pandemic, a mental health deterioration has been detected in the general population and especially in people affected by pre-existing psychiatric conditions. Furthermore, mental healthcare has moved toward online treatment. ED people showed a trend toward worsening of ED-specific psychopathology and impairment in general psychopathology. The most common vulnerability mechanisms were social isolation and feelings of uncertainty, while heightened self-care and reduced social pressure were resilience factors. The online treatment, although raising many concerns related to its quality, was considered the best alternative to the face-to-face approach. These findings may support the idea that stressful events contribute to the exacerbation of ED psychopathology and highlight the relevance of internalizing symptoms in EDs. The identification of putative risk and resilience variables as well as of subjective factors affecting online treatment perception may inform healthcare professionals and may promote more personalized approaches.

Adolescents and young adults engaged with pro-eating disorder social media: eating disorder and comorbid psychopathology, health care utilization, treatment barriers, and opinions on harnessing technology for treatment

PURPOSE

The purpose of this study was to examine exposure (i.e., seeing, following, posting) to body image content emphasizing a thin ideal on various social media platforms and probable eating disorder (ED) diagnoses, ED-related quality of life, and psychiatric comorbidities (i.e., depression, anxiety) among adolescents and young adult females recruited via social media who endorsed viewing and/or posting pro-ED online content. We also investigated health care utilization, treatment barriers, and opinions on harnessing technology for treatment.

METHODS

Participants were 405 adolescent and young adult females engaged with pro-ED social media. We reported on study constructs for the sample as a whole, as well as on differences between age groups.

RESULTS

Eighty-four percent of participants' self-reported symptoms were consistent with a clinical/subclinical ED, and this was slightly more common among young adults. Participants endorsed reduced ED-related quality of life, as well as comorbid depression and anxiety. Among those with clinical/subclinical EDs, only 14% had received treatment. The most common treatment barriers were believing the problem was not serious enough and believing one should help themselves. The majority of participants approved of harnessing technology for treatment.

CONCLUSIONS

Results provide support for engagement with pro-ED online content serving as a potential indicator of ED symptoms and suggest promise for facilitating linkage from social media to technology-enhanced interventions.

Treatment engagement and effectiveness of an internet-delivered cognitive behavioral therapy program at a university counseling center

Objective: Technology can provide affordable, accessible mental health care and some research suggests internet-delivered Cognitive Behavior Therapy (iCBT) can be an effective treatment for various problems and can be an affordable, accessible alternative to traditional treatments. Advantages of iCBT over face-to-face therapy include lower cost, no travel time, easy access, no waitlists, and trackable progress. To our knowledge there have been no studies of iCBT programs used during the course of routine care. This study evaluated the usage and effectiveness of one iCBT program, SilverCloud (SC), in a university counseling center. Methods: Participants (N = 5568) were students at a large, private western university. Participants were either self-referred to the program, chose to enroll at intake as a standalone intervention, or were referred by their treating clinician as an adjunct to regular treatment. Data was analyzed using regression models with robust standard errors that allowed us to take into account the fact that there may be an effect of participants seeing the same therapist. Results: Results indicated that all three groups had comparable outcomes. However, usage was generally low (less than 10% of the program) and SC usage accounted for less than 1% of the variance in outcome. Conclusions: These results suggest that internet-delivered therapy may be a viable alternative to in-person therapy.

Family-based treatment via videoconference: Clinical recommendations for treatment providers during COVID-19 and beyond

The necessity to employ distance-based methods to deliver on-going eating disorder care due to the novel coronavirus (COVID-19) pandemic represents a dramatic and urgent shift in treatment delivery. Yet, TeleHealth treatments for eating disorders in youth have not been adequately researched or rigorously tested. Based on clinical experience within our clinic and research programs, we aim to highlight the common challenges clinicians may encounter in providing family-based treatment (FBT) via TeleHealth for children and adolescents with anorexia nervosa and bulimia nervosa. We also discuss possible solutions and offer practical considerations for providers delivering FBT in this format. Additional research in TeleHealth treatment for eating disorders in youth may lead to improved access, efficiency, and effectiveness of FBT delivered via videoconferencing.

Access to evidence-based care for eating disorders during the COVID-19 crisis

The COVID-19 pandemic has forced an abrupt change in the delivery of clinical services, including for individuals with an eating disorder. We present this Virtual Issue as a resource for the eating disorder community to showcase research published in the International Journal of Eating Disorders that provides information on effective strategies to help address the challenges arising from COVID-19-related disruptions. Articles included describe original research or systematic reviews on obstacles to health services use and strategies to improve access to care; technological tools to provide or enhance interventions; patients' and clinicians' attitudes or perspectives on using digital tools for clinical care; factors influencing therapeutic alliance; and ideas for improving reach and uptake of digital interventions. We hope that readers will find ways to observe and record their own experiences during this global crisis; the experiences of people at risk for developing or exhibiting an eating disorder; and the experiences of those who care for people with an eating disorder. These lived experiences will be invaluable in formulating hypotheses for future studies in service of advancing the understanding of eating disorders and improving interventions and policies for reducing the burden of suffering attributable to eating disorders.

Adherence as a predictor of dropout in Internet-based guided self-help for adults with binge-eating disorder and overweight or obesity

OBJECTIVE

Internet-based guided self-help (GSH-I) is an efficacious treatment for adults with binge-eating disorder (BED) and overweight or obesity. Although broadly accessible, high dropout from GSH-I has been reported. However, little is known about the factors explaining dropout from GSH-I, including patients' adherence to treatment.

METHOD

Within a randomized trial on the treatment of BED, adherence to 4-month GSH-I was objectively assessed in N = 89 patients with BED and overweight or obesity. Objective adherence and subjective treatment evaluation were evaluated as predictors of dropout from GSH-I, defined as having accessed 5 or less of 11 modules. Cutoffs with optimal sensitivity and specificity were derived using Receiver Operating Characteristics curves analysis, and baseline sociodemographic and clinical correlates were determined.

RESULTS

According to our definition, n = 22 (24.7%) patients were defined as dropouts. Results of the full logistic regression model accounted for 72% of the variance in dropout and all objective adherence parameters (i.e., number of messages exchanged, days with a completed food diary, and days spent per module), but not patients' subjective GSH-I evaluation significantly predicted dropout. Specifically, not completing the food diary in week 7 had maximized sensitivity and specificity in predicting dropout. Patients' body mass index was positively associated with the number of messages exchanged between patients and coaches. No other associations between baseline variables and objective adherence were found.

DISCUSSION

Patients at risk for dropout from GSH-I can be reliably identified via monitoring of objective adherence and may be provided with additional interventions to prevent dropout.

Etiologic and treatment conceptualizations of disordered eating symptoms among mainland Chinese therapists

OBJECTIVE

Reports of disordered eating are increasing in mainland China; however, little is known regarding Chinese psychotherapists' conceptualizations of disordered eating symptomatology. This study explores Chinese psychotherapists' conceptualizations of binge eating (BE)/vomiting symptoms and treatment considerations.

METHOD

In-depth, semi-structured interviews were conducted with mainland Chinese psychotherapists (N = 41) in Mandarin. Participants were given a hypothetical case and provided their conceptualization of the patient's BE/vomiting etiology and treatment recommendations. Etiological conceptualizations were coded using directed content analysis, and treatment recommendations were grouped by intervention strategy.

RESULTS

Participants described psychosocial risk factors for BE/vomiting including intrapersonal characteristics and the childhood family environment, but rarely discussed genetic and neurobiological factors. Few participants reported that they would prioritize the BE/vomiting symptoms in treatment and their specific treatment recommendations varied widely.

DISCUSSION

Most research on BE/vomiting behaviors in the literature is based on Western samples with little attention to mainland Chinese populations. Participants in this study provided conceptualizations of risk factors and treatment recommendations that could generally find evidence in the existing Western literature, even if some theories are no longer supported by updated Western research and the participants focused primarily on psychosocial risks as opposed to genetic/neurobiological factors. It will be important for future research to ascertain mainland Chinese therapists' understanding of these additional types of risk. These findings also suggest a disconnect between clinical findings on neurobiological risks and Chinese therapists' knowledge and/or perceived clinical utility of these risks. Implications for treatment and research dissemination to diverse global communities are discussed.

Evaluating reach, adoption, implementation and maintenance of Internet-based interventions to prevent eating disorders in adolescents: a systematic review

BACKGROUND

Past research has yielded promising results on the effectiveness of Internet-based interventions to prevent eating disorders (EDs) in adolescents, but further information is needed to evaluate the public health impact of their large-scale dissemination. This article used an established framework to systematically review the extent to which indicators of the reach, effectiveness, adoption, implementation and maintenance [cf. Reach-Effectiveness-Adoption-Implementation-Maintenance (RE-AIM)-framework] of universal and targeted online ED prevention programmes are reported in the literature, in order to estimate their future dissemination potential.

METHODS

The literature search was conducted on PubMed, Web of Science and PsycINFO, and complemented by searching existing reviews and the reference lists of the studies included. Twenty-two studies published between 2000 and April 2019 met the inclusion criteria. We extracted data on a total of 43 indicators, within RE-AIM dimensions for each article, including qualitative coding of fostering and hindering factors.

RESULTS

Reach (55.0%) and implementation (54.0%) were the dimensions reported on most frequently, followed by effectiveness (46.8%), adoption (34.7%) and maintenance (18.2%). While internal validity indicators were frequently reported (e.g. sample size, effects and intervention intensity), most studies failed to report on elements of external validity, such as representativeness of participants and settings, adoption rates, implementation costs and programme sustainability.

CONCLUSIONS

Evidence indicates that Internet-based ED prevention programmes can reach a large number of adolescents and can be feasibly implemented in school settings. However, given the paucity of large-scale dissemination studies available for review, the degree to which schools are willing to adopt preventive interventions, as well as the transferability of programmes to different settings and geographical regions remains unclear.

[The Importance of Social Exchange for Internet-based Eating Disorder Prevention]

The Importance of Social Exchange for Internet-based Eating Disorder Prevention Internet-based interventions have the potential to complement routine care mental health services. Yet, dissemination and implementation into routine care is challenging and often fails. From a public health point of view, facilitating access to care and dissemination of prevention have great potential to reduce eating disorder related suffering in the general population. In order to exploit that potential effective strategies to involve users in internet-based prevention are of utmost importance. User-behaviors of N = 980 predominantly female (80 %) participants with an average age of 19.4 years (SD = 7.0) of an internet-based intervention for the prevention of eating disorders (ProYouth) were analyzed. Specifically, differences in users' pathways between early and late phases of participation were compared in order to identify patterns of program utilization that are associated with elevated adherence. During their first login, users explore all modules of the platform. Enduring participation is characterized by increased usage of the modules that offer social exchange with other participants, i. e. the forums and the chat. Static modules, e. g., psychoeducation, are rarely accessed after the first login. Additionally, enduring users were more often female, older, and displayed higher levels of psychological impairment (ps < .001). The results support the relevance of social exchange for the adherence in internet-based interventions for the prevention of eating disorders.

Internet-based aftercare for patients with personality disorders and trauma-related disorders: A pilot study

Preventing readmission after hospital discharge is a major issue with regard to the continuity of patients' recovery process and the financial burden on the healthcare system, but adequate aftercare services are lacking. Therefore, a pilot study was conducted to examine the feasibility and acceptability of an Internet-based aftercare program for patients with personality disorders (PD) and / or trauma-related disorders as well as to obtain a preliminary estimate of effects on symptomatology and readmission. Patients' satisfaction with the program and symptomatology (KPD-38, BDI-II) were assessed prior to hospital discharge (t1) and after three months of participation (t2). Log data on program utilization (i.e., logins, page hits, and chat use) were automatically assessed via server logs. N = 31 of 45 eligible patients consented to participate. 84% used the intervention at least once. The average duration of participation was 63 days (SD = 4.6). Patients attended on average 7.2 out of 12 group chat sessions (SD = 4.0). Findings indicate very high acceptance of and satisfaction with the intervention. Symptomatology on all outcomes was stable, no deteriorations could be observed. 20% reported readmission within the aftercare period. Efficacy and cost-effectiveness should be tested with a large-scale randomized controlled trial.

Optimizing eating disorder treatment outcomes for individuals identified via screening: An idea worth researching

In recent years, online screens have been commonly used to identify individuals who may have eating disorders (EDs), many of whom may be interested in treatment. We describe a new empirical approach that takes advantage of current evidence on empirically supported, effective treatments, while at the same time, uses modern statistical frameworks and experimental designs, data-driven science, and user-centered design methods to study ways to expand the reach of programs, enhance our understanding of what works for whom, and improve outcomes, overall and in subpopulations. The research would focus on individuals with EDs identified through screening and would use continuously monitored data, and interactions of interventions/approaches to optimize reach, uptake, engagement, and outcome. Outcome would be assessed at the population, rather than individual level. The idea worth researching is to determine if an optimization outcome model produces significantly higher rates of clinical improvement at a population level than do current approaches, in which traditional interventions are only offered to the few people who are interested in and able to access them.

Screening and offering online programs for eating disorders: Reach, pathology, and differences across eating disorder status groups at 28 U.S. universities

OBJECTIVE

The Internet-based Healthy Body Image (HBI) Program, which uses online screening to identify individuals at low risk of, high risk of, or with an eating disorder (ED) and then directs users to tailored, evidence-based online or in-person interventions to address individuals' risk or clinical status, was deployed at 28 U.S. universities as part of a randomized controlled trial. The purpose of this study is to report on: (a) reach of HBI, (b) screen results, and (c) differences across ED status groups.

METHOD

All students on participating campuses ages 18 years or older were eligible, although recruitment primarily targeted undergraduate females.

RESULTS

The screen was completed 4,894 times, with an average of 1.9% of the undergraduate female student body on each campus taking the screen. ED risk in participating students was high-nearly 60% of students screened were identified as being at high risk for ED onset or having an ED. Key differences emerged across ED status groups on demographics, recruitment method, ED pathology, psychiatric comorbidity, and ED risk factors, highlighting increasing pathology and impairment in the high-risk group.

DISCUSSION

Findings suggest efforts are needed to increase reach of programs like HBI. Results also highlight the increasing pathology and impairment in the high-risk group and the importance of programs such as HBI, which provide access to timely screening and intervention to prevent onset of clinical EDs.

User-centered design for technology-enabled services for eating disorders

OBJECTIVE

Technology-enabled services frequently have limited reach and suboptimal engagement when implemented in real-world settings. One reason for these implementation failures is that technology-enabled services are not designed for the users and contexts in which they will be implemented. User-centered design is an approach to designing technologies and services that is grounded in information from the stakeholders who will be using or impacted by them, and the contexts for implementation. The purpose of this article is to present user-centered design methods that can be applied to technology-enabled services for eating disorders.

METHOD

We provide an overview of the user-centered design process, which is iterative and involves stakeholders throughout. One model is presented that depicts six phases of a user-centered design process: investigate, ideate, prototype, evaluate, refine and develop, and validate.

RESULTS

We then review how user-centered design approaches can be applied to designing technology-enabled services for patients with eating disorders, and we integrate a hypothetical case example that demonstrates the application of these techniques to designing a technology-enabled service for binge eating. Most of the user-centered design techniques can be implemented relatively quickly, allowing us to rapidly learn what stakeholders want and to identify problems before devoting time and resources to developing and delivering technologies and services.

DISCUSSION

Through this work, we show how designing services that fit into the patterns and routines that stakeholders already are doing can ensure that services are relevant to stakeholders and meet their needs, potentially improving engagement and clinical impact.

RESUMEN

Los servicios habilitados tecnológicamente frecuentemente tienen un alcance limitado y un involucramiento subóptimo cuando son implementados en escenarios del mundo real. Una razón para estas fallas de implementación es que los servicios habilitados tecnológicamente no están diseñados para los usuarios y contextos en los que serán implementados. El diseño centrado en el usuario es un abordaje para diseñar tecnologías y servicios que está basado en información de las partes interesadas que estarán haciendo uso o impactados por ellos, y los contextos para implementación. El propósito de este estudio es presentar métodos de diseños centrados en el usuario que pueden ser aplicados a servicios habilitados tecnológicamente para trastornos de la conducta alimentaria. Ofrecemos una visión general del proceso de diseño centrado en el usuario, que es iterative e involucra a las partes interesadas a lo largo de todo el proceso. Hemos presentado un modelo que describe seis fases de un proceso de diseño centrado en el usuario: investigar, idear, crear prototipos, evaluar, refinar y desarrollar, y validar. Luego revisamos cómo estos abordajes de diseño centrado en el usuario pueden ser aplicados para diseñar servicios habilitados tecnológicamente para pacientes con trastornos de la conducta alimentaria, e integramos un ejemplo de caso hipotético que demuestra la aplicación de estas técnicas para diseñar un servicio habilitado tecnológicamente para comer en atracones. Muchas de las técnicas de diseño centrado en el usuario pueden ser implementadas relativamente rápido, lo que nos permite aprender rápidamente lo que las partes interesadas quieren e identificar los problemas antes de dedicarles tiempo y recursos al desarrollo y entrega de tecnologías y servicios. A través de este trabajo, mostramos cómo el diseño de servicios que se ajustan a los patrones y rutinas que las partes interesadas ya están haciendo puede garantizar que los servicios sean relevantes para los interesados y que satisfagan sus necesidades, lo que podría mejorar la participación y el impacto clínico.

Screening for Eating Disorders on College Campuses: a Review of the Recent Literature

PURPOSE OF REVIEW

This paper provides a review of the recent literature on screening for eating disorders (EDs) on college campuses, and reports on methodology, prevalence rates, treatment receipt, and ED screening tools.

RECENT FINDINGS

Recent research highlights relatively high prevalence rates of EDs among students on college campuses, with the majority of studies demonstrating elevated prevalence compared to the general population. Among students who screened positive for an ED, approximately 20% or less reported having received treatment for their ED. Findings also revealed various recruitment strategies, methods, ED screening tools, and clinical cutoffs used to study this topic, making it challenging to draw firm conclusions about prevalence of EDs on college campuses. Recent research on ED screening on college campuses reveals that EDs are a significant problem among college students, and there is a marked treatment gap between those who need care and those who receive it. Implications and future research are discussed.

Mobile Health Adoption in Mental Health: User Experience of a Mobile Health App for Patients With an Eating Disorder

Background

Despite the worldwide growth in mobile health (mHealth) tools and the possible benefits for both patients and health care providers, the overall adoption levels of mHealth tools by health professionals remain relatively low.

Objective

This study aimed (1) to investigate attitudes of health care providers and mHealth experts toward mHealth tools in the health context in general, and this study aimed (2) to test the acceptability and feasibility of a specific mHealth tool for patients with an eating disorder (ED), called TCApp, among patients and ED specialists.

Methods

To this purpose, we conducted an explorative qualitative study with 4 in-depth group discussions with several groups of stakeholders: our first focus group was conducted with 11 experts on mHealth from the Catalan Association of Health Entities; the second focus group included 10 health care professionals from the Spanish College of Doctors of Barcelona; the third focus group involved 9 patients with an ED who had used the TCApp over a 12-week period, and the fourth and last focus group involved 8 ED specialists who had monitored such ED patients on the Web.

Results

The focus groups showed that health care providers and mHealth experts reported barriers for mHealth adoption more often than facilitators, indicating that mHealth techniques are difficult to obtain and use. Most barriers were attributed to external factors relating to the human or organizational environment (ie, lack of time because of workload, lack of direct interest on a legislative or political level) rather than being attributed to internal factors relating to individual obstacles. The results of the mHealth intervention study indicate that the TCApp was considered as easy to use and useful, although patients and the ED specialists monitoring them on the Web reported different adoption problems, such as the inability to personalize the app, a lack of motivational and interactive components, or difficulties in adhering to the study protocol.

Conclusions

In general, this paper indicates that both health professionals and patients foresee difficulties that need to be addressed before comprehensive adoption and usage of mHealth techniques can be effectively implemented. Such findings are in line with previous studies, suggesting that although they acknowledge their possible benefits and cost-effectiveness, health care providers are quite resistant and conservative about integrating mHealth technologies in their daily practice.

Dissemination of an Internet-Based Program for the Prevention and Early Intervention in Eating Disorders

Objective: Research on the dissemination of e-mental health interventions is in an early stage, so that little is known about the reach, costs, participant characteristics, and patterns of program utilization associated with different recruitment strategies and access paths. This study investigated differences between user groups informed about an Internet-based program for the prevention and early intervention in eating disorders via different recruitment channels. Method: Participant characteristics and user behavior of 3548 participants in the Internet-based program ProYouth were analyzed. Participants were informed about ProYouth via different channels (e. g., print materials, high school, Internet). Results: Results indicate significant relationships between access paths and both user characteristics and program utilization. Participants who were informed about ProYouth at their high schools were more likely to be male, younger, and at lower risk of developing eating disorders. In contrast, other recruitment channels (e. g., Internet, print materials) resulted in participants with significantly higher risk and symptom levels who used the program more frequently and with higher intensity. Conclusion: Efforts aimed at the dissemination of Internet-based interventions should consider the effects that different recruitment channels and access paths may have on sample composition and utilization of the intervention.

Annual Research Review: Expanding mental health services through novel models of intervention delivery

Currently, in the United States and worldwide, the vast majority of children and adolescents in need of mental health services receive no treatment. Although there are many barriers, a key barrier is the dominant model of delivering psychosocial interventions. That model includes one-to-one, in-person treatment, with a trained mental health professional, provided in clinical setting (e.g., clinic, private practice office, health-care facility). That model greatly limits the scale and reach of psychosocial interventions. The article discusses many novel models of delivering interventions that permit scaling treatment to encompass children and adolescents who are not likely to receive services. Special attention is accorded the use of social media, socially assistive robots, and social networks that not only convey the ability to scale interventions but also encompass interventions that depart from the usual forms of intervention that currently dominate psychosocial treatment research.

Binge-eating disorder treatment goes online - feasibility, usability, and treatment outcome of an Internet-based treatment for binge-eating disorder: study protocol for a three-arm randomized controlled trial including an immediate treatment, a waitlist, and a placebo control group

Background

Binge-eating disorder (BED) is characterized by recurrent episodes of loss of control over eating and is related to a higher prevalence of other mental disorders and somatic consequences associated with overweight and obesity. In community-based samples, 2–4% of women and 1–3% men are diagnosed with BED. Psychotherapeutic interventions focusing on maintenance factors of disturbed eating behavior have proven to be effective. However, treatment access is limited for a considerable number of patients with BED. A lack of specialized institutions and treatment resources, but also long distances to treatment facilities for people living in remote or rural areas are often causes of insufficient care. Internet-based guided self-help (GSH) programs have the potential to fill this gap.

Methods

This project aims to develop and evaluate an Internet-based treatment for BED derived from an evidence-based manualized cognitive behavioral therapy (CBT). The primary goal is to test feasibility and suitability of the Internet-based program and to evaluate the treatment outcome in comparison to a pure and a placebo-inspired waitlist control group (i.e. reduction of binge-eating episodes and eating disorder pathology as primary outcome variables). In total, 60 women and men aged 18–70 years with a BED diagnosis will be recruited. The Internet-based GSH treatment comprises eight sessions followed by three booster sessions. The placebo-inspired waitlist control group receives weekly messages containing information increasing positive expectations regarding the treatment effects during the four-week waiting period. The pure waitlist control group receives weekly messages simply asking patients to fill in a short questionnaire.

Discussion

The access to evidence-based treatments for BED might be made easier using an Internet-based GSH approach. The present study protocol presents a randomized controlled trial. As well as evaluating the suitability and efficacy of the Internet-based GSH treatment, there will also be a prelimarily investigation on the influence of positive expectations (placebo) for a therapeutic intervention on core symptoms.

Efficacy and cost-effectiveness of Internet-based selective eating disorder prevention: study protocol for a randomized controlled trial within the ProHEAD Consortium

BACKGROUND

The development of efficacious, cost-effective, and widely accessible programs for the prevention of eating disorders (EDs) is crucial in order to reduce the ED-related burden of illness. Programs using dissonance-based and cognitive behavioral approaches are most effective for the selective prevention of ED. Internet-based delivery is assumed to maximize the reach and impact of preventive efforts. However, the current evidence for Internet-based ED prevention is limited. The present trial evaluates the efficacy and cost-effectiveness of two new interventions (based on dissonance theory and principles of cognitive behavioral therapy (CBT)) that are implemented as add-ons to the existing Internet-based ED prevention program ProYouth.

METHODS

The trial is one of five sub-projects of the German multicenter consortium ProHEAD. It is a three-arm, parallel, randomized controlled superiority trial. Participants will be randomized to (1) the online program ProYouth (active control condition) or (2) ProYouth plus a structured dissonance-based module or (3) ProYouth plus a CBT-based chat group intervention. As part of ProHEAD, a representative school-based sample of N = 15,000 students (≥ 12 years) will be screened for mental health problems. N = 309 participants at risk for ED (assessed with the Weight Concerns Scale (WCS) and the Short Evaluation of Eating Disorders (SEED)) will be included in the present trial. Online assessments will be conducted at baseline, at end of intervention (6 weeks), at 6 months follow-up, and - as part of ProHEAD - at 12 and 24 months follow-up. The primary outcome is ED-related impairment (assessed with the Child version of the Eating Disorder Examination-Questionnaire (ChEDE-Q)) at the end of the intervention. Secondary outcomes include ED-related symptomatology at follow-up, ED-related stigma, ED-related help-seeking, and acceptance of and compliance with the interventions. For the health economic evaluation data on costs of the interventions, healthcare utilization and health-related quality of life will be assessed.

DISCUSSION

This is the first study augmenting a flexible prevention approach such as ProYouth with structured evidence-based modules in order to overcome some of the key limitations in the current practice of ED prevention.

Prevention of eating disorders: 2018 in review

This article reviews the 10 prevention-related publications in Eating Disorders: The Journal of Treatment & Prevention during 2018. Two models frame this analysis. This first is the Mental Health Intervention Spectrum from health promotion → types of prevention → case identification and referral → treatment (recovery). The second parses the phases of prevention into rationale, theory, and methodology → clarification of risk factors, including very high risk, shading into warning signs → implications for specific preventive interventions → design innovation and feasibility (pilot) research → efficacy and effectiveness research → program dissemination. Collectively, the articles illustrate how complex and demanding the field of prevention is, with respect to, for example, phases of program development, the multidimensional ecology of interventions, and methodological requirements for demonstrating that a program deserves to be designated "evidence-based." A subset of the articles also illustrates how far the increasingly broad and dynamic field of prevention has advanced. Examples include models of eating disorder development in high-risk populations such as people with type 1 diabetes; prevention programming for young children; and after-school preventive interventions that combine dissonance-based lessons with empowering participation in community advocacy and activism.

Adapting a Technology-Based Eating Disorder Model for Athletes

Eating disorders (EDs) are common amongst athletes, yet few receive treatment. Given that athletes have a unique set of risk factors for eating disorders and are faced with additional barriers to treatment, new models outside of face-to-face treatment are necessary to reach the population and provide more affordable, tailored, evidence-based care. One solution is to use digital mental health programs to provide primary or supplemental therapy. Digital programs can provide accessibility and privacy, and recent advancements allow for more personalized online experiences. However, there have been no studies to date that integrate technology-based tools to address the especially high prevalence rates of EDs in athletes. This paper describes how an integrated model that includes online screening linked to guided self-help programs, all adapted specifically for athletes, can be used to provide prevention and intervention of EDs in athletes.

A preliminary trial of an online dissonance-based eating disorder intervention

OBJECTIVE

We conducted a controlled randomized preliminary trial of an expanded online version of the Body Project (n = 46) compared to an assessment-only control condition (n = 36) via a longitudinal design (baseline, postintervention, 2-month follow-up) in a community sample of women (N = 82) with clinical (n = 53) and subclinical (n = 29) eating disorder symptoms.

METHOD

The traditional content of the Body Project was modified to include verbal, written, and behavioral exercises designed to dissuade objectification and maladaptive social comparison and adapted to an online format. Body dissatisfaction, self-esteem, self-objectification, thin-ideal internalization, maladaptive social comparison, trait anxiety, positive affect, negative affect, and eating disorder symptomatology were evaluated in the control and the online expanded Body Project condition at baseline, postintervention, and 2-month follow-up.

RESULTS

A 2 (condition: online expanded Body Project, control) × 3 (time: baseline, postintervention, 2-month follow-up) mixed factorial multivariate analysis of variance (MANOVA) was conducted to examine statistically significant group differences. As predicted, results indicated a statistically significant condition × time interaction.

CONCLUSIONS

Participants in the expanded online Body Project condition showed significant reductions in eating disorder symptoms and several associated psychological risk correlates from baseline to postintervention and follow-up; contrary to predictions, eating disorder symptoms and risk correlates were not significantly lower in the online expanded Body Project condition compared to the waitlist control condition at postintervention or 2-month follow-up.

"I would love to have online support but I don't trust it": Positive and negative views of technology from the perspective of those with eating disorders in Canada

This qualitative study aims to explore how individuals who are seeking help and support for eating disorders use various forms of technology. Fifteen participants, recruited from an Eating Disorder Program in a hospital setting and an eating disorder community support centre, voluntarily participated in focus groups and individual interviews in 2015. The authors used thematic analysis to code and analyse the qualitative data, and three themes were identified: safety, connection and technology development. This study identifies the need for technology use to be addressed and integrated into clinical services for eating disorders, as well as for safe and helpful technology tools to be developed for this population.

Cost-effectiveness of the mobile application TCApp combined with face-to-face CBT treatment compared to face-to-face CBT treatment alone for patients with an eating disorder: study protocol of a multi-centre randomised controlled trial

BACKGROUND

The clinical utility of the existing apps for people with eating disorders (EDs) is not clear. The TCApp has been specifically developed for people with EDs, is based on the principles of Cognitive Behavioural Treatment (CBT) and allows a bidirectional link between the patient and the therapist. The objectives of the study are, first, to assess the clinical efficacy of a combined intervention for Eating Disorders (EDs) that includes an online intervention through the TCApp plus standard face-to-face CBT in comparison to standard face-to-face CBT alone, and second, to examine the cost-effectiveness of the TCApp and identify potential predicting, moderating and mediating variables that promote or hinder the implementation of the TCApp in ED units in Spain.

METHODS

The study methodology is that of a randomised controlled trial combining qualitative and quantitative methods, with a 6-month follow-up. Approximately 250 patients over 12 years old with a diagnosis of an ED from several ED units in Spain will be randomised to one of two different conditions. Participants, their caregivers, healthcare professionals and technical staff involved in the development and maintenance of the application will be assessed at baseline (T0), post-intervention (T1) and at 6 months follow-up (T2). Primary outcome measures will include ED symptomatology while secondary measures will include general psychopathology and quality of life for patients, quality of life and caregiving experience for family caregivers and adoption-related variables for all participants involved, such as perceived usability, user's satisfaction and technology acceptance. For the cost-effectiveness analysis, we will assess quality-adjusted life years (QALYs); total societal cost will be estimated using costs to patients and the health plan, and other related costs.

DISCUSSION

The study will provide an important advance in the treatment of EDs; in the long term, it is expected to improve the quality of patient care and the treatment efficacy and to reduce waiting lists as well as direct and indirect costs associated with the treatment of EDs in Spain.

Using internet-based self-help to bridge waiting time for face-to-face outpatient treatment for Bulimia Nervosa, Binge Eating Disorder and related disorders: Study protocol of a randomized controlled trial

BACKGROUND

Eating disorders are serious conditions associated with an impaired health-related quality of life and increased healthcare utilization and costs. Despite the existence of evidence-based treatments, access to treatment is often delayed due to insufficient health care resources. Internet-based self-help interventions may have the potential to successfully bridge waiting time for face-to-face outpatient treatment and, thus, contribute to overcoming treatment gaps. However, little is known about the feasibility of implementing such interventions into routine healthcare. The aim of this study is to analyze the effects and feasibility of an Internet-based self-help intervention (everyBody Plus) specifically designed for patients with Bulimia Nervosa, Binge Eating Disorder and other specified feeding and eating disorders (OSFED) on a waiting list for outpatient face-to-face treatment. The aim of this paper is to describe the study protocol.

METHODS

A multi-country randomized controlled trial will be conducted in Germany and the UK. N = 275 female patients awaiting outpatient treatment will be randomly allocated either to the guided online self-help intervention "everyBody Plus" or a waitlist control group condition without access to the intervention. everyBody Plus comprises eight weekly sessions that cover topics related to eating and exercise patterns, coping with negative emotions and stress as well as improving body image. Participants will receive weekly individualized feedback based on their self-monitoring and journal entries. Assessments will take place at baseline, post-intervention as well as at 6- and 12-months follow up. In addition, all participants will be asked to monitor core eating disorder symptoms weekly to provide data on the primary outcome. The primary outcome will be number of weeks after randomization until a patient achieves a clinically relevant improvement in core symptoms (BMI, binge eating, compensatory behaviors) for the first time. Secondary outcomes include frequency of core symptoms and eating disorder related attitudes and behaviors, as well as associated psychopathology. Additional secondary outcomes will be the participating therapists' confidence in treating eating disorders as well as perceived benefits of everyBody Plus for patients.

DISCUSSION

To the best of our knowledge, this is the first randomized controlled trial examining the effects of Internet-based self-help for outpatients with eating disorders awaiting face-to-face outpatient treatment. If proven to be effective and successfully implemented, Internet-based self-help programs might be used as a first step of treatment within a stepped-care approach, thus reducing burden and cost for both patients and health care providers.

everyBody-Tailored online health promotion and eating disorder prevention for women: Study protocol of a dissemination trial

BACKGROUND

Although there is extensive evidence for the efficacy of online eating disorder (ED) prevention programs in clinical trials, these programs have rarely been adopted beyond the trial phase and offered to a wider audience. As risk factors for eating disorders are partly associated with overweight and overweight in turn is correlated to disordered eating, this study will offer a combined eating disorder prevention program which also promotes a balanced lifestyle to normal weight and overweight individuals alike. The efficacy of the program has been proven in previous trials. The study aims to evaluate the dissemination of a combined eating disorder prevention and health promotion program (everyBody) to women of all age groups and varying levels of ED risk status in the general population.

METHODS

A dissemination trial will be conducted in German-speaking countries, including 4160 women from the general population. Participants will be screened to exclude participants who are likely to have an ED. Eligible participants will be allocated to one of five program arms based on their BMI and respective ED symptoms. The guided program consists of 4 to 12 weeks of weekly sessions offering CBT-based exercises, psychoeducational material, self-monitoring, and group discussions. Outcomes will be assessed according to the RE-AIM model, including measures of effectiveness, reach, adoption, implementation, and maintenance of the program.

DISCUSSION/CONCLUSIONS

This trial aims to disseminate a combined ED prevention and health promotion program in the general population, offering universal, selective and indicated prevention in one program. To our knowledge, it is the first trial to systematically evaluate dissemination efforts based on the RE-AIM model. This trial will be conducted as part of the EU-funded ICare (Integrating Technology into Mental Health Care Delivery in Europe) project.

Associations between eating disorder related symptoms and participants' utilization of an individualized Internet-based prevention and early intervention program

OBJECTIVE

Flexible, individualized interventions allow participants to adjust the intensity of support to their current needs. Between-persons, participants with greater needs can receive more intense support, within-persons, participants can adjust utilization to their current level of symptoms. The purpose of the present study was to analyze associations between ED-related symptoms and utilization of the individualized program ProYouth both between- and within-persons, aiming to investigate whether participants adapt utilization intensity to their current needs.

METHOD

Generalized estimated equations (GEEs) were used to analyze log data on program utilization (monthly page visits, monthly use of chats and forum) assessed via server logs and self-reported data on ED-related symptoms from N = 394 ProYouth participants who provided longitudinal data for at least two months.

RESULTS

Between-persons, page visits per month were significantly associated with compensatory behavior, body dissatisfaction, and binge eating. Monthly use of the more intense modules with personal support chat and forum was associated with the frequency of compensatory behavior. Within-persons, unbalanced nutrition and dieting showed the strongest associations with monthly page visits. Monthly use of chats and forum was significantly associated with compensatory behavior and unbalanced nutrition and dieting.

DISCUSSION

Results indicate that program utilization is associated with ED-related symptoms between- as well as within-persons. The individualized, flexible approach of ProYouth thus seems to be a promising way for Internet-based provision of combined prevention and early intervention programs addressing ED.

Internet-delivered eating disorder prevention: A randomized controlled trial of dissonance-based and cognitive-behavioral interventions

OBJECTIVE

The current study evaluated two web-based programs for eating disorder prevention in high-risk, predominantly ethnic minority women.

METHOD

Two hundred and seventy-one women with elevated weight concerns were randomized to Internet dissonance-based intervention (DBI-I), Internet cognitive-behavioral intervention (CBI-I), or no intervention (NI). Both interventions consisted of four weekly online sessions. Participants were assessed at pre- and post intervention. Outcome measures included eating pathology, body dissatisfaction, dieting, thin-ideal internalization, and depression.

RESULTS

At postintervention, DBI-I and CBI-I led to greater reductions in body dissatisfaction, thin-ideal internalization, and depression than NI. In addition, CBI-I was effective at reducing dieting and composite eating pathology relative to NI. No outcome differences were found between the active conditions. Moderation analyses suggested that both active conditions were more effective for ethnic minorities than Whites relative to NI.

DISCUSSION

Results suggest that both DBI-I and CBI-I are effective at reducing eating disorder risk factors in a high-risk, predominantly minority population relative to no intervention.

Addressing the treatment gap: A key challenge for extending evidence-based psychosocial interventions

Remarkable progress has been made in developing psychosocial interventions for a broad range of psychiatric disorders for children, adolescents, and adults. In addition many efforts are well underway to address the research-practice gap, which refers to the dissemination evidence-based treatments from controlled settings to clinical care. The present article focuses on the treatment gap, which refers to the discrepancy in the proportion of the population in need of services and the proportion that actually receives them. Currently, in the United States (and worldwide), the vast majority of individuals in need of mental health services receive no treatment. Although there are many reasons, the dominant model of delivering psychosocial interventions in both research and clinical practice makes it difficult to scale treatment to reach the large swaths of individuals in need. That model includes one-to-one, in person treatment, with a trained mental health professional, and provided in clinical setting (e.g., clinic, private practice office, health-care facility). The article discusses the development of delivery models that would permit reaching more individuals in need, highlights criteria for developing such models, and illustrates novel models already available. The article proposes that our next challenge is to reach individuals in need with the many excellent interventions we have developed but through a diversified set of delivery models.

Evolution of cognitive-behavioral therapy for eating disorders

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.
