What this trial studies

The intervention adapts Family-Based Treatment into a guided self-help (GSH FBT) model delivered via video and written materials with a licensed therapist acting as a coach. Implementation teams at participating sites will train providers and use standardized materials to support fidelity and consistent delivery. The study uses a mixed-methods design across Canadian sites to measure changes in wait times, patient and family outcomes, provider experiences, and treatment fidelity. Qualitative interviews and focus groups with families and care teams will capture the real-world acceptability and barriers to implementation.

Who should consider this trial

Good fit: Ideal candidates are families with an adolescent formally diagnosed with anorexia nervosa who have internet access and can participate in English or French.

Not a fit: Adolescents who are medically unstable, require hospitalization, have active substance dependence, are pregnant, have a physical condition affecting weight, or weigh under 75% expected are unlikely to benefit from this outpatient guided self-help model.

Why it matters

Potential benefit: If successful, this approach could reduce wait times and provide faster, more standardized treatment that helps adolescents recover more quickly from anorexia nervosa.

How similar studies have performed: Traditional Family-Based Treatment is well supported, and early, smaller studies of guided self-help FBT adaptations show promise but are less established than full FBT.
