目标。这项研究评估了安全选择的长期有效性，这是一个基于理论的、多组成部分的教育计划，旨在减少高中生的性危险行为，增加预防艾滋病毒、其他性传播疾病和怀孕的保护行为。这项研究使用了一项随机对照试验，涉及加利福尼亚州和德克萨斯州的20所高中。从1993年秋季学期(基线)到1996年春季学期(31个月随访期)，对3869名九年级学生进行了31个月的跟踪调查。数据是通过由训练有素的数据收集者管理的自我报告调查收集的。随访31个月，有效率为79%。更安全的选择对涉及避孕套使用的措施影响最大。该计划减少了调查前三个月不使用避孕套的性行为频率，减少了与学生发生不使用避孕套的性伴侣的数量，并增加了避孕套的使用和其他防止上次性交时怀孕的保护措施。更安全的选择也改善了13个心理社会变量中的7个，其中许多与避孕套的使用有关，但对性行为起始率没有显著影响。安全选择计划有效地减少了艾滋病毒、其他性传播疾病和怀孕的重要危险行为，并增强了此类行为的大多数心理社会决定因素。
Objectives. This study evaluated the long-term effectiveness of Safer Choices, a theory-based, multi-component educational program designed to reduce sexual risk behaviors and increase protective behaviors in preventing HIV, other STDs, and pregnancy among high school students.Methods. The study used a randomized controlled trial involving 20 high schools in California and Texas. A cohort of 3869 ninth-grade students was tracked for 31 months from fall semester 1993 (baseline) to spring semester 1996 (31-month follow-up). Data were collected using self-report surveys administered by trained data collectors. Response rate at 31-month follow-up was 79%.Results. Safer Choices had its greatest effect on measures involving condom use. The program reduced the frequency of intercourse without a condom during the three months prior to the survey, reduced the number of sexual partners with whom students had intercourse without a condom, and increased use of condoms and other protection against pregnancy at last intercourse. Safer Choices also improved 7 of 13 psychosocial variables, many related to condom use, but did not have a significant effect upon rates of sexual initiation.Conclusions. The Safer Choices program was effective in reducing important risk behaviors for HIV, other STDs, and pregnancy and in enhancing most psychosocial determinants of such behavior.
