Stimulant Abuser Groups to Engage in 12-Step (STAGE-12): Evaluation of a Combined Individual-Group Intervention to Reduce Stimulant and Other Drug Use by Increasing 12-Step Involvement

Active Healing through the Stage-12 Program & Lifestyle Changes cover

The primary objective of this protocol was to evaluate the degree to which a combined group and individual 12-Step facilitative intervention, Stimulant Abuser Groups to Engage in 12 -Step (STAGE-12), improves substance -related outcomes compared to treatment was usual (TAU) without STAGE-12 among stimulant abusers. For this protocol, STAGE-12 will be integrated into treatment as usual. This was a randomized, 2-group design comparing STAGE-12 integrated into TAU (STAGE-12 /TAU) to TAU without STAGE-12 for stimulant abusers receiving formal substance abuse treatment in participating community-based treatment programs (CTP). A total of approximately 450 stimulant users were recruited from 10 CTPS.
