Functional Family Therapy for Young People in Treatment for Nonopioid Drug Use: A Systematic Review

This review evaluates the evidence on the effects of functional family therapy (FFT) on drug abuse reduction for young people in treatment for nonopioid drug use. We followed Campbell Collaboration guidelines to conduct a systematic review of randomized and nonrandomized trials. The search yielded two studies that met inclusion criteria. Only one study provided numerical results on the effect of FFT on drug use reduction. There is insufficient evidence to allow any conclusion to be drawn on the effect of FFT for young people in treatment for nonopioid drug use. There is a need for more research and particularly for more methodologically rigorous studies in the field of treatment for young drug users
