Background
Evidence-based, single-session STI/HIV interventions to reduce sexual risk-taking are potentially effective options for implementation in resource-limited settings and may solve problems associated with poor participant retention.
Purpose
To estimate the efficacy of single-session, behavioral interventions in reducing unprotected sex or increasing condom use.
Methods
Data sources were searched through April 2013 producing 67 single-session interventions (52 unique reports; N = 20,039) that included outcomes on condom use and/or unprotected sex.
Results
Overall, participants in single-session interventions reduced sexual risk taking relative to control groups (d+ = 0.19, 95% CI = 0.11, 0.27). Within-group effects of the interventions were larger than the between-groups effects when compared to controls.
Conclusions
Brief, targeted single-session sexual risk reduction interventions demonstrate a small but significant effect, and should be prioritized.
