Study protocol for training providers in private practice in family-based treatment for adolescents with anorexia nervosa: A randomized controlled feasibility trial

Abstract

Background: Private practice clinicians make up approximately 50% of US mental health outpatient providers and treat a high number of eating disorder patients. While family-based treatment (FBT) is a first-line treatment for adolescent anorexia nervosa (AN), private practice clinicians experience difficulties receiving training in evidence-based treatments such as FBT. This report outlines the study protocol for a randomized control trial (RCT) training private practice clinicians in FBT for adolescent AN (NCT04428580).

Methods: In this study, we intend to recruit 140 private practice mental health practitioners and randomize them to complete either a standard webinar-based online training or an enhanced online training that incorporates additional modules related to the putative mechanisms of treatment effect in FBT (i.e., use of externalization and agnosticism). Following the training, participants will begin expert case consultation for an adolescent with AN using FBT from their private practice.

Conclusion: Based on preliminary studies suggesting the importance of enhanced skills related to agnosticism and externalization, we hypothesize that feasibility data will support a larger randomized clinical trial (RCT) and that the enhanced training arm will significantly improve FBT knowledge and skills compared to the standard webinar training arm. We also expect that patient weight gain early in treatment will be associated with clinician fidelity to the inventions used in FBT regardless of training type.
