HIV /STD Prevention Program for Middle School Students

描述（由申请人提供）：本研究将开发和评估一个多组分的艾滋病毒，性病和怀孕预防干预中学生。 研究设计将包括在德克萨斯州休斯顿市中心的16所中学进行的随机对照试验。 大约1000名七年级学生将被招募到研究中，并将在两年的时间内进行跟踪。 干预措施将包括一个适合年龄的课堂课程和一个基于光盘的定制干预措施，在七年级和八年级提供。 课程由受过训练的辅导员讲授，重点是拒绝和沟通技巧、健康的关系、态度、自我效能和与约会和性行为有关的同伴规范。 它将改编自现有的艾滋病毒、性传播疾病和怀孕预防课程《更安全的选择》，该课程已被证明能有效减少高中生的性冒险行为。 考虑到中学生身体和情感发展的范围，学生还将通过基于光盘的艾滋病毒、性传播疾病和怀孕预防干预措施获得个性化的学习机会，该干预措施将提供针对学生目前的行为或关于约会和性行为的意图的信息、资源和技能培养练习。 干预的效果将通过评估性风险行为（没有发生性行为的学生比例，目前性活跃的学生中发生无保护性行为的比例，性伴侣的数量）进行评估。 由于社区合作对于在中学一级成功实施艾滋病毒/性传播疾病预防计划至关重要，我们将与学区工作人员、教师、家长和社区代表密切合作，开发一种获得基于社区的投入和支持的模式，以制定和实施计划。

DESCRIPTION (provided by applicant): This study will develop and evaluate a multi-component HIV, STD and pregnancy prevention intervention for middle school students. The study design will consist of a randomized controlled trial conducted in sixteen inner-city middle schools in Houston, Texas. Approximately 1000 7th grade students will be recruited into the study and will be followed over a two-year period. The intervention will consist of an age-appropriate classroom curriculum and a CD-ROM-based tailored intervention delivered in 7th and 8th grade. The curriculum, delivered by trained facilitators, will focus on refusal and communication skills, healthy relationships, attitudes, self-efficacy and peer norms related to dating and sexual behavior. It will be adapted from an existing HIV, STD and pregnancy prevention curriculum Safer Choices, which has been shown to be effective at reducing sexual risk-taking behavior among high school students. Given the range in physical and emotional development among middle school youth, students will also receive individualized learning opportunities by means of a CD-ROM-based HIV, STD and pregnancy prevention intervention which will provide information, resources and skill-building exercises tailored to the student's current behavior or intentions regarding dating and sexual behavior. The effect of the intervention will be evaluated by assessing sexual risk-taking behaviors (proportion of students not having sex, proportion of currently sexually active students who have unprotected sex, number of sexual partners). Since community collaboration is essential for successful implementation of HIV/STD prevention programs at the middle school level, we shall work closely with school district personnel, teachers, parents and community representatives to develop a model for obtaining -community-based input and support for program development and implementation.
