Predictors of early response in conjoint and separated models of family-based treatment for adolescent anorexia nervosa

Abstract

Objective: Early response, as indicated by early weight gain, in family-based treatment (FBT) for adolescent anorexia nervosa (AN) predicts remission at end of treatment. However, little is known about what factors contribute to early response. Further, no previous studies have examined early response to separated forms of FBT. Method: Data from a randomised clinical trial of conjoint FBT and separated FBT (parent-focused treatment, PFT) were analysed to examine the timing and amount of early weight gain that predicted remission and identify factors associated with early response. Results: Weight gain of at least 2.80 kg in FBT (N = 55) and 2.28 kg in PFT (N = 51), by Session 5, were the bes..
