- Brief Summary
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
- Detailed Description
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.

Group Intervention Description Mobile Coached Intervention SilverCloud Health Mobile Intervention Participants randomized to the mobile intervention condition will receive access to the mobile app for 6 consecutive months. Participants will still be able to access other usual care options and will be encouraged to follow the discharge plan provided to them by the eating disorder program from which they were discharged. Mobile Coached Intervention Plus Social Networking SilverCloud Health Mobile Intervention Participants randomized to the mobile intervention plus social networking condition will receive access to the mobile app, as well as Facebook social networking component, for 6 consecutive months. Participants will still be able to access other usual care options and will be encouraged to follow the discharge plan provided to them by the eating disorder program from which they were discharged.
- Primary Outcome Measures
Name Time Method 1. 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. baseline, 6 months, and 9 months 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. Change in EDE-Q scores will be compared from baseline to 6 months and baseline to 9 months.
- Secondary Outcome Measures
Name Time Method Effectiveness of the mobile app conditions, compared to referral to usual care, in changing clinical impairment, as assessed by the Clinical Impairment Assessment. baseline, 6 months, and 9 months Investigators will use the Clinical Impairment Assessment (CIA), which is a 16-item self-report measure of the severity of psychosocial impairment due to eating disorder features. Scores range from 0 to 48 with higher scores indicating higher levels of impairment. Change in CIA scores will be compared from baseline to 6 months and baseline to 9 months.
Effectiveness of the mobile app conditions, compared to referral to usual care, in changing eating disorder behaviors. baseline, 6 months, and 9 months 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. Change in EDE-Q behavior frequencies will be compared from baseline to 6 months and baseline to 9 months.
Effectiveness of the mobile app conditions, compared to referral to usual care, in changing depression and suicidal ideation, as assessed by the Patient Health Questionnaire. baseline, 6 months, and 9 months Investigators will use the Patient Health Questionnaire (PHQ-9), a 9-item measure that is widely used to assess presence of possible depression and severity, as well as suicidality. Scores possible range from 0 to 27, with higher scores indicating greater severity of depression. Change in PHQ scores will be compared from baseline to 6 months and baseline to 9 months.
Effectiveness of the mobile app conditions, compared to referral to usual care, in changing Body Mass Index (BMI). baseline, 6 months, and 9 months 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. Change in BMI will be compared from baseline to 6 months and baseline to 9 months.
