Summary

This trial tests a peer-led program called PEGISUS to reduce substance use and promote fair gender beliefs among 264 young people (ages 16-24) in vocational training in Zambia, Zimbabwe, and South Africa. Participants in peer groups will attend eight sessions, while a control group gets standard training and a healthcare referral. The study will measure substance use at 12 and 24 weeks.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: PEGISUS peer education program (behavioral intervention)
What this could lead to: If it works, this could provide a low-cost, scalable way to reduce substance use and improve gender attitudes among young people in vocational training.
What could go wrong: This is a small pilot trial, so results may not be generalizable. The intervention is behavioral and relies on self-report, which can be biased.
