Peer Education for Gender Inclusion and Substance Use in Southern Africa

The goal of this trial is to test the effectiveness of a brief, behavioral peer group intervention called "PEGISUS" (Peer Education for Gender Inclusion and Substance Use in Southern Africa), on substance use, which will be embedded within existing vocational training programs in Zambia, Zimbabwe, and South Africa. Established peer groups who receive the PEGISUS intervention will complete nine sessions of an adapted intervention for substance use and gender equitable beliefs, embedded into vocational training programs. This will be compared to a standard of care control condition, which involves the vocational training program that is offered through the partner organization and a healthcare referral for substance use. The vocational training program partners are Sozo Foundation (South Africa), BuildIt International (Zambia), and Masvingo Polytechnic (Zimbabwe). Participants in both conditions will complete assessments at baseline, 12-weeks follow-up, and 24-weeks follow-up, consisting of self-reported questionnaires.
