GSSW faculty member, Kim Bender, along with her colleagues Stephen Tripodi, Christy Sarteschi, and Michael Vaughn conducted a meta-analysis of intervention studies that were published from 1960 – 2008 which examined cannabis use treatment for adolescents (ages 12-19).1 Fifteen research studies met the criteria for inclusion in the analysis. Their results found that not only do interventions to reduce cannabis use among adolescents have a medium effect, but that the effect size of individual treatment and family treatment approaches were similarly effective. Among family-centered approaches, three approaches emerged as having larger effect sizes: Integrated Family and Cognitive Behavioral Therapy, Multidimensional Family Therapy, and Teaching Family. For individual approaches, Motivational Interviewing, Behavioral Therapy, and Cognitive Behavioral Therapy emerged as the approaches that were most successful. The findings of this study not only contribute to the literature on evidence-based practice, but also addresses a treatment area where little intervention research has been conducted.
