Overview
This randomized, controlled effectiveness trial will assess outcomes, implementation, and mechanisms of two psychological treatments for adolescent anorexia nervosa (AN) delivered in the home setting, in the context of community-based mental health. Adolescents with AN-spectrum disorders (n=50) and their caregivers will be randomly assigned to either family-based treatment or integrated family therapy delivered in the home. Caregivers and adolescents will provide data on weight, eating, and putative treatment mechanisms, including caregiver self-efficacy, adolescent distress, and generalizability of treatment skills. Treatment feasibility, acceptability, and appropriateness will be measured among providers and participating families. The proposed study has clear potential to advance scientific and clinical understanding of the real-world effectiveness of psychological treatments for AN, including whether adapting them for the home setting may improve accessibility and effects on treatment outcome
