Can adaptive treatment improve outcomes in family-based therapy for adolescents with anorexia nervosa? Feasibility and treatment effects of a multi-site treatment study.
OBJECTIVE Adolescents with Anorexia Nervosa ( AN ) , treated with family-based treatment ( FBT )  who fail to gain 2.3 kg by the fourth week of treatment have a 40 - 50 % lower chance of recovery than those who do . Because of the high risk of developing enduring AN , improving outcomes in this group of poor responders is essential . This study examines the feasibility and effects of a novel adaptive treatment ( i.e. , Intensive Parental Coaching-IPC ) aim ed at enhancing parental self-efficacy related to re-feeding skills in poor early responders to FBT . METHOD 45 adolescents ( 12 - 18 years of age ) meeting DSM TR IV criteria for AN were r and omized in an unbalanced design ( 10 to st and ard FBT ; 35 to the adaptive arm ) . Attrition , suitability , expectancy rates , weight change , and psychopathology were compared between groups . OUTCOMES There were no differences in rates of attrition , suitability , expectancy ratings , or most clinical outcomes between r and omized groups . However , the group of poor early responders that received IPC achieved full weight restoration ( > 95 % of expected mean BMI ) by EOT at similar rates as those who had responded early . CONCLUSIONS The results of this study suggest that it is feasible to use an adaptive design to study the treatment effect of IPC for those who do not gain adequate weight by session 4 of FBT . The results also suggest that using IPC for poor early responders significantly improves weight recovery rates to levels comparable to those who respond early . A sufficiently powered study is needed to confirm these promising findings
