Feasibility of decision rule-based treatment of comorbid youth: A pilot randomized control trial.

This study examined the feasibility, acceptability, and preliminary efficacy of a decision rule driven treatment for youth with comorbid conduct problems and depression. A randomized, controlled, repeated measures design was used to compare two treatment approaches: Decision-Rule Based Treatment (DR) and Sequential Treatment (SEQ). Participants included 30 children (ages 8-14; 66% female; 80% Caucasian) who met criteria for a depressive disorder (major depressive disorder and/or dysthymia) and a conduct problem disorder (oppositional defiant disorder and/or conduct disorder). Assessments were conducted at baseline, post-treatment, and six-month follow-up. Treatment adherence, attendance, and session evaluations ratings indicate that the treatments were feasible to implement and acceptable to parents and youth in both conditions. Both treatments showed similar remission of internalizing and externalizing diagnoses. Participants in DR showed significantly greater improvements at six-month follow-up in child-reported depressive symptom severity compared to SEQ. Both DR and SEQ conditions showed significantly lower behavior problems at end of treatment and six-month follow-up. DR showed significant reductions in emotion dysregulation at 6-month follow-up, while SEQ did not. Findings suggest that a decision rule based intervention holds promise as a feasible and acceptable treatment with high rates of remittance.
