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. On the role-play measure, those with higher baseline scores in the low-pressure situation improved significantly only in the three-session intervention; in the high-pressure situation, the participants reported significantly higher scores in the seven-session intervention, and those with higher scores improved the most. Results suggest the importance of multisession HIV intervention programs to be delivered with fidelity in community settings.
研究了一项针对151名年龄在13至24岁青少年的艾滋病毒干预项目的效果，这些青少年被随机分配到：(a) 七节时长各为1.5小时的课程（共10.5小时）；(b) 三节时长各为3.5小时的课程（共10.5小时）；或(c) 无干预组。在三节和七节的小组干预中，运用认知行为干预策略，以社交技能以及与艾滋病毒相关的信念、认知和规范为目标。回归分析表明，在3个月的时间里，与其他组相比，七节课程组的无保护风险行为次数和性伴侣数量更低。介导风险行为的因素变化复杂。例如，与其他组相比，七节课程组中最初脆弱性得分较低的青少年，其感知到的脆弱性有所增加。与三节课程组相比，七节课程组中最初得分较低者对使用避孕套的自我认可也更高。与其他组相比，最初得分较低者在三节课程组中的风险规避和使用避孕套的自我效能显著更高。在角色扮演测试中，在低压情境下基线得分较高者仅在三节课程干预中有显著改善；在高压情境下，参与者在七节课程干预中的得分显著更高，且得分较高者改善最大。结果表明，在社区环境中忠实地实施多节次艾滋病毒干预项目具有重要意义。
