Audience age at time of intervention is thought to be a critical variable influencing the effectiveness of adolescent sexual risk reduction interventions. Yet studies to date have not compared outcomes based on age at the time of intervention delivery. The present authors examined outcomes among 598 youth who were sequentially involved in two randomized controlled trials of sexual risk prevention interventions, one delivered in grade 6 and the other in grade 10. Four groups were examined: those who received (1) both intervention conditions, (2) intervention in grade 6 and the control condition in grade 10; (3) the control condition in grade 6 and intervention in grade 10; and (4) both control conditions. Intentions, perceptions, condom-use skills, and HIV-related knowledge were assessed over 60 months. Youth who received both interventions had the greatest increase in condom-use skills, whereas those who received intervention in grade 6 had higher scores for knowledge and intention. Findings suggest that youth receive the most protection with early and repeated exposure to interventions. Modified Author Abstract.
