Timing of HIV interventions on reductions in sexual risk among adolescents.
Examined the effectiveness of an HIV intervention program among 151 adolescents ages 13 to 24 years who were randomly assigned to (a) seven sessions of 1.5 hr each (10.5 hr) ; (b) three sessions of 3.5 hr each (10.5 hr) ; or (c) a no-intervention condition.
Using cognitive-behavioral intervention strategies, social skills and HIV-related beliefs, perceptions, and norms were targeted in both the three-and seven-session, small-group intervention conditions.
Regression analysis indicated that over 3 months, the number of unprotected risk acts and the number of sexual partners were lower in the seven-session condition compared to the other conditions.
Factors mediating risk acts changed in a complex manner : For example, perceived vulnerability increased for those with initially lower vulnerability scores among youths in the seven-session condition compared to others.
Self-approval of condom use was also higher for those with initially low scores in the seven-session compared to the three-session condition.
Self-efficacy for risk avoidance and condom use was significantly higher in the three-session condition for those with initially low scores compared to other groups. (...)
