BMC Psychiatry. 2025 Nov 6;25(1):1066. doi: 10.1186/s12888-025-07545-1.

ABSTRACT

BACKGROUND: Guided self-help family-based treatment (GSH-FBT) is emerging as a promising, more efficient alternative to traditional family-based treatment (FBT). The present study is designed to examine the real-world implementation of GSH-FBT at pediatric treatment sites across nine provinces in Canada.

METHODS: Implementation teams at each site consisting of a GSH-FBT coach, a medical provider, and a program administrator will be formed. Clinician coaches will be trained in this new modality and supported with weekly GSH-FBT consultation. Each site will recruit ten families with an adolescent with anorexia nervosa and the parents will undergo ten virtual GSH-FBT sessions. The implementation approach will be evaluated using qualitative and quantitative methods. Outcomes of interest include (1) treatment fidelity, (2) treatment wait times, (3) change in adolescent symptoms and parent/caregiver self-efficacy, (4) change in provider readiness, attitudes, and confidence towards the intervention, and (5) the overall experience of the implementation of the intervention from the perspective of the provider teams, and participant families.

DISCUSSION: The findings of this study will help to identify factors important to the acceptability and implementation of GSH-FBT in real-world clinical settings.
