An important phase of HIV prevention research is replicating successful interventions with different groups and in different settings.
Be Proud! Be Responsible!, a successful intervention originally targeting black urban males and carried out in nonschool settings, was presented in health classes at urban and suburban schools with diverse student bodies. A group-randomized intervention study, which included 1,357 ninth and 10th graders from 10 paired schools in a Midwestern metropolitan area, was conducted in 2000-2002. Half the schools received the intervention, and half received a general health promotion program. Students' reports of their sexual behavior and selected cognitive mediators were analyzed immediately following the programs and four and 12 months later.
Compared with students who received the control curriculum, students exposed to the intervention reported significantly greater knowledge of HIV, other STDs and condoms; greater confidence in their ability to control sexual impulses, to use condoms and to negotiate the use of condoms; and stronger intentions to use condoms. Stratified analyses revealed that the strongest intervention impacts were on knowledge and efficacy among males and students attending suburban schools. The intervention had no impact on sexual initiation, frequency of intercourse or condom use.
Schools are a logical and viable setting for the dissemination and acquisition of information about HIV, including prevention strategies. However, the behavioral impact of an intervention may not be easily transferable when the program is taught outside a carefully controlled, nonschool setting.
艾滋病病毒预防研究的一个重要阶段是在不同群体和不同环境中复制成功的干预措施。
“要自豪!要负责!”是一项最初针对城市黑人男性并在非学校环境中开展的成功干预措施,现于城市和郊区学校的健康课程中向学生群体多样化的学校进行推广。2000年至2002年,开展了一项群组随机干预研究,该研究纳入了来自中西部大都市地区10所配对学校的1357名九年级和十年级学生。一半学校接受干预措施,另一半学校接受一般健康促进项目。在项目结束后、四个月后和十二个月后,对学生的性行为报告和选定的认知调节因素进行了分析。
与接受对照课程的学生相比,接受干预措施的学生报告称,他们对艾滋病病毒、其他性传播疾病和避孕套的了解明显更多;对自己控制性冲动、使用避孕套和协商使用避孕套的能力更有信心;使用避孕套的意愿更强。分层分析显示,干预措施的最大影响体现在男性和郊区学校学生的知识和效能方面。干预措施对性行为开始、性交频率或避孕套使用没有影响。
学校是传播和获取艾滋病病毒相关信息(包括预防策略)的合理且可行的场所。然而,当在精心控制的非学校环境之外开展该项目时,干预措施对行为的影响可能不易转移。
