Few studies have tested schoolwide interventions to reduce sexual risk behavior, and none have demonstrated significant schoolwide effects. This study evaluates the schoolwide effects of Safer Choices, a multicomponent, behavioral theory-based HIV, STD, and pregnancy prevention program, on risk behavior, school climate, and psychosocial variables. Twenty urban high schools were randomized, and cross-sectional samples of classes were surveyed at baseline, the end of intervention (19 months after baseline), and 31 months afterbaseline. At 19 months, the program had a positive effect on the frequency of sex without a condom. At 31 months, students in Safer Choices schools reported having sexual intercourse without a condom with fewer partners. The program positively affected psychosocial variables and school climate for HIV/STD and pregnancy prevention. The program did not influence the prevalence of recent sexual intercourse. Schoolwide changes in condomuse demonstrated that aschool-based program can reduce the sexual risk behavior of adolescents.
很少有研究测试过全校范围的干预措施以减少性风险行为，而且没有一项研究表明在全校范围内有显著效果。本研究评估了“更安全选择”（Safer Choices）这一基于行为理论的多成分艾滋病毒、性传播感染和预防怀孕项目在全校范围内对风险行为、学校氛围和心理社会变量的影响。20所城市高中被随机分组，在基线期、干预结束时（基线期后19个月）和基线期后31个月对班级的横断面样本进行了调查。在19个月时，该项目对无保护性行为的频率有积极影响。在31个月时，参与“更安全选择”项目学校的学生报告称，无保护性行为的性伴侣较少。该项目对艾滋病毒/性传播感染和预防怀孕的心理社会变量和学校氛围有积极影响。该项目并未影响近期性行为的发生率。全校范围内避孕套使用情况的变化表明，一项基于学校的项目可以减少青少年的性风险行为。
