This document summarizes a study that compared the effectiveness of routine family therapy (RFT) to treatment as usual (TAU) for adolescent behavior problems. 205 adolescents were randomly assigned to RFT or TAU. Both treatments showed improvements in externalizing and internalizing symptoms, delinquency, and substance use, with some outcomes showing greater improvements for RFT. The study provides preliminary evidence that RFT can be effective when delivered with fidelity in usual care settings, though more research is still needed.
