Aim 1: Use a highly efficient experimental design to estimate the unique contribution of key components of Community Wise in: a) reducing AIDU frequency and b) increasing the percentage of participants abstinent over five months. Components tested are the presence or absence of: (a) Critical Dialogue; (b) Quality-of-Life-Wheel; (c) Capacity Building Project; and (d) group facilitation by a peer versus a licensed clinician. A factorial experiment will be used to detect effects of individual components and three-way interactions.
