Abstract
The present study explored the acceptability, feasibility, fidelity, and outcomes of a young adult adaptation of multidimensional family therapy (MDFT), an evidence-based family treatment originally developed for adolescents. Participants included 22 individuals between the ages of 19 to 25 who were enrolled in a criminal drug court program. MDFT was found to be feasible and was delivered with strong fidelity to young adults and their families. Participants reported high satisfaction with MDFT, and 95% completed treatment. Analyses revealed statistically significant decreases in substance use on all indicators from baseline to the 6-month follow-up. Significant improvements were also noted in vocational functioning, including a 73% increase in full-time employment from baseline to 6-month follow-up. Criminal justice outcomes included a significant decrease in legal risk, and 86% of study participants had no rearrests from baseline through the 18-month follow-up period. The article concludes with recommendations for implementing family-based interventions with young adults, as well as future research directions in this important area.
