Helping HAND: Healing Anorexia Nervosa Digitally

Washington University School of Medicine90 enrolled

Overview

The proposed project will develop and pilot a coached mobile app, including a social networking component, for individuals with anorexia nervosa to use in the post-acute period

Anorexia nervosa (AN) is a costly and life-threatening illness. Patients with severe AN are often treated in the acute setting, but relapse after treatment is common. Further, the discharge criterion in acute settings is typically weight restoration. However, research has indicated that weight-based recovery is not "enough" and that full recovery involves physical, behavioral, and psychological components. Cognitive-behavioral therapy (CBT) is useful with this population, including following discharge, and may aid in addressing psychological symptoms, achieving full recovery, and decreasing relapse. However, very few patients have access to providers trained in these techniques. mHealth technologies have great potential to exponentially increase access to high-quality services for the post-acute treatment of AN by addressing barriers to treatment, but to date, research on these approaches has been extremely limited. A guided self-help CBT-based mobile app, StudentBodies-Eating Disorders (SB-ED), has been successfully developed, demonstrating effectiveness among college women with binge/purge-type EDs. At the same time, there is demonstrated support for in-person CBT for the post-acute care and relapse prevention of adult AN. The overarching goal of this R34 is thus to develop and test a CBT-based, coached mobile app to address the post-acute care and relapse prevention.

Interventions

SilverCloud Health Mobile InterventionDEVICE

SilverCloud Health is a mobile mental health platform offering cognitive-behavioral therapy-based guided self-help programs, including one for anorexia nervosa developed by our team. Participants in this arm will receive the support of a coach to guide them through the program. Participants will be able to communicate with their coach within the program.

Social Networking Intervention: FacebookDEVICE

Facebook is a social networking site that will offer participants the opportunity to interact with study team posts, post themselves, and connect with others in the study experiencing similar struggles in a private group

Outcomes

Primary Outcomes

Effectiveness of the Mobile App Conditions, Compared to Referral to Usual Care, in Changing Eating Disorder Psychopathology, as Assessed by the Eating Disorder Examination-Questionnaire.

Investigators will use the Eating Disorder Examination-Questionnaire (EDE-Q), a 28-item measure derived from a diagnostic interview, the standard measure of eating disorder psychopathology. The main outcome variable will be the EDE-Q Global score, an overall measure of eating disorder psychopathology. Scores possible range from 0 to 6, with higher scores indicating greater eating disorder psychopathology.

Time frame: baseline, 6 weeks, 6 months, and 9 months

Secondary Outcomes

Number of Participants With Any Reported Eating Behaviors in the Mobile App Conditions Compared to Referral to Usual Care.

Investigators will use the Eating Disorder Examination-Questionnaire (EDE-Q), a 28-item measure derived from a diagnostic interview, the standard measure of eating disorder psychopathology. For this secondary outcome, investigators will examine eating disorder behavior frequencies from the EDE-Q.

Time frame: baseline, 6 weeks, 6 months, and 9 months

Effectiveness of the Mobile App Conditions, Compared to Referral to Usual Care, in Changing Body Mass Index (BMI).

Investigators will use current BMI as derived from self-reported height, which has shown to be accurate in adult ED populations, and weight assessed by a digital wireless scale. At each of the study timepoints, a study coordinator will schedule a time with the participant to take their weight while they are on a Zoom call with the coordinator. Participants will be instructed to take off their shoes, wear light clothing, and empty their pockets, similar to the instructions that would be provided if this measurement were being taken in person. Given the use of a wireless scale, the measurement will be able to be immediately and automatically sent to the research team.
