title: Single-Session Behavioral Interventions for Sexual Risk Reduction: A Meta-Analysis.
abstract: 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.
  
  
  
  The purpose of the study is to estimate the efficacy of single-session, behavioral interventions in reducing unprotected sex or increasing condom use.
  
  
  
  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.
  
  
  
  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.
  
  
  
  Brief, targeted single-session sexual risk reduction interventions demonstrate a small but significant effect and should be prioritized.
