Brief Summary

With an incidence rate of about 1%, Anorexia Nervosa (AN) is a serious mental disorder associated with high mortality, morbidity, and cost. AN in youth is more responsive to early treatment but becomes highly resistant once it has taken an enduring course. The first-line treatment for adolescents with AN is Family Based Treatment (FBT). While FBT can be delivered using videoconferencing (FBT-V), therapists' limited availability hampers scalability. Guided self-help (GSH) versions of efficacious treatments have been used to scale and increase access to care. The main aim of this proposed comparative effectiveness study is to confirm that clinical improvements in GSH-FBT are achieved with greater efficiency than FBT-V in generalizable clinical settings.

GroupInterventionDescription
FBT via Videoconferencing (FBT-V)FBT via Videoconferencing15 60-minute sessions of 3-phase manualized FBT modified for videoconferencing will be delivered to participants randomized to this treatment by therapists trained in FBT. The first phase encourages parental management of weight restoration (approximately 8 weekly sessions); the second phase promotes a developmentally appropriate transition back to adolescent management of weight restoration and maintenance under parental supervision (approximately 4 bi-weekly sessions), and the third phase focuses on adolescent development (approximately 3 monthly sessions). Each session consists of 10 minutes with the adolescent individually to discuss progress and the adolescent's perspective on treatment, followed by 50 minutes with the entire family.
Online Guided Self-Help-Family-based Treatment (GSH-FBT)Online Guided Self-Help-Family-based TreatmentGSH-FBT consists of 10 20-minute parent-only sessions over 9 months. The guidance portion is manualized and will be delivered by a clinician familiar with both the online modules and FBT, who acts as a "coach." Sessions follow an online curriculum containing a total of 65 short videos. Each lecture series is comprised of a written introduction orienting the viewer to the videos, 5-9 short videos (\< 7 minutes each), and assigned reading from the parent education manual, Help Your Teenager Beat an Eating Disorder. In line with GSH approaches, coaches direct parents to watch or re-watch specific videos contained in the online platform related to their questions.
Primary Outcome Measures
NameTimeMethod
Ratio of therapist hours to %EBW changeAssessed from baseline through end of treatment (EOT)

The investigators will compare GSH-FBT and FBT-V groups at EOT in terms of the change in %EBW from baseline divided by total therapist time utilized. Estimated Body Weight (EBW) percentages used will be calculated using Center for Disease Control metrics in children and adolescents. Total therapist time utilized will be collected based on video records of actual sessions spent with participants.

Secondary Outcome Measures
NameTimeMethod
Beck Depression Inventory (BDI)These assessments will be collected bi-weekly (sessions 2, 4, 6, 8) and at all major assessment points (BL, 3 months within treatment, EOT, 6 and 12-month follow-up)

The BDI is a measure with sound psychometric properties and was validated on a diverse sample. It has been used in numerous studies of adolescent depression. This measure also includes questions about suicidal ideation and intent and will be used to assess suicide during the study. These assessments will be collected bi-weekly (sessions 2, 4, 6, 8) and at all major assessment points. It takes about 10 minutes to complete.

Beck Anxiety Inventory (BAI)Baseline, sessions 2, 4, 6, 8, and EOT

The BAI is a 21-item questionnaire about anxiety that has sound psychometric properties and was validated on a diverse sample. Assessments will be collected at baseline, sessions 2, 4, 6, 8, and EOT.

Eating Disorder Examination (EDE)Baseline (before beginning treatment); 3 months within treatment; 9 months (EOT); and at 6- and 12-month follow-up

The EDE is a standardized investigator-based interview that measures the severity of the characteristic psychopathology of eating disorders. The psychometric properties of the EDE are sound and validated in diverse samples. It takes about 1 hour to complete.
