Study Overview

Brief Summary

This study evaluates a brief motivation-building intervention for parents and teens to reduce truancy and substance use. It is hypothesized that the motivational intervention will result in better outcomes compared to an education-only intervention.

Detailed Description

Adolescents who use marijuana and are truant from school are a high-risk population with increased likelihood of substance use disorders, criminal justice involvement, and long-term impairments in vocational, family, and peer domains.

This study will test a theory-driven intervention for early adolescent marijuana using, truant youth identified through Rhode Island Truancy and Family Courts. Adolescents will be randomly assigned to one of the 2 conditions: a motivational interview versus psychoeducation.
