Brief Summary

We propose to pilot test an adapted version of the Teen Marijuana Check Up (TMCU) for persistent cannabis users with first episode psychosis (FEP) in Coordinated Specialty Care (CSC). The adapted version of the TMCU will include tailoring to risks of persistent cannabis use in FEP, providing education on lower risk cannabis use, and adding a session to address collaborative planning to maintain CSC engagement and antipsychotic adherence and to reduce harm associated with cannabis use.

Teen Marijuana Checkup - adapted

EXPERIMENTAL

Teen Marijuana Checkup will be adapted for youth and young adults with first episode psychosis. The Teen Marijuana Checkup includes two intervention sessions. In Session 1, the interventionist uses motivational interviewing skills to hear the adolescent's history and current concerns with marijuana. The personalized feedback report generated from the baseline assessment is reviewed. In Session 2, the interventionist elicits change talk and guides discussion on making changes to reduce or stop marijuana use.
