Summary

This trial tests whether the MOON program, a five-session online bystander intervention, can reduce sexual violence among Portuguese university students. The program teaches participants to recognize risky situations, challenge harmful beliefs, and safely intervene. Researchers will compare students who take the program with those who do not, measuring changes in attitudes, empathy, and actual bystander behavior over nine months.

What this could mean

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

Active substance: MOON Program (Moving ON against sexual violence) — a 5-session online bystander intervention program with psychoeducation and skills training
What this could lead to: If effective, the MOON program could provide a scalable, evidence-based tool for reducing sexual violence on college campuses by empowering students to intervene.
What could go wrong: This is a relatively small trial (200 participants) testing a new program. Results may not generalize to other universities or cultures, and long-term behavior change is hard to sustain.
