DESCRIPTION (provided by applicant): While a number of HIV prevention programs have been evaluated in school settings, much of the focus of this research has been the content of the curriculum; as a result, we still know little about the specific facets of the classroom environment that may yield the strongest effects of an effective school-based FHV, other STD, and pregnancy prevention curriculum. In the proposed research, we plan to bring together expertise from our research in health communications and our research in classroom instruction, combining Donohew's individual differences model of information exposure with Eccles' stage-environment fit theory to assess the impact of curricular, teacher, instructional and student individual difference variables on HIV-related mediating and outcome variables while developing an effective prevention program. Specific aims of the project are, within a randomized control trial in high school health classrooms, to (1) adapt a modified version of a skills-based, MV, other STD, and pregnancy-prevention curriculum to be more appropriate for the needs of impulsive decision makers, in order to bring about desired behavior change in sexual decision-making; (2) assess the impact of characteristics of the instructional environment in health classrooms (i.e., teacher efficacy, teacher immediacy, value orientation, and teacher identity) in order to identify effective instructional methods and teacher characteristics; (3) implement reinforcement and relevance of the curriculum across other classes and content areas in order to foster more effective learning of the material; and 4) Evaluate the interaction among the student, the teacher, and the curriculum to determine optimal learning environments that lead to sustained behavior change. The proposed study, including over 5,000 students and 10-12 schools, will be conducted over a period of five years. During the first three years, six separate intervention implementation studies will occur (two consecutive interventions per year), with the design for five of the six intervention studies as experimental, with randomization occurring by school. In Years 4 and 5, we will also examine the effects of a combined "best practices" classroom based intervention by comparing two groups of students randomized by schools: a comparison condition, with a skills-based HIV/pregnancy prevention curriculum or the optimal version that contains the most successful elements tested in the three preceding years. The analytic design will include individual, classroom, teacher, and school levels, to be assessed through hierarchical linear modeling or other tests of differences.

描述（由申请人提供）：虽然一些艾滋病毒预防计划已在学校环境中进行了评估，这项研究的重点一直是课程的内容;因此，我们仍然对教室环境的具体方面知之甚少，这些方面可能会产生有效的校本FHV，其他性病和预防怀孕课程的最强效果。 在拟议的研究中，我们计划汇集专业知识，从我们的研究在健康传播和我们的研究在课堂教学中，结合Donohew的信息暴露的个体差异模型与Eccles的阶段环境配合理论，以评估课程，教师，教学和学生的影响个体差异变量对艾滋病毒相关的中介和结果变量，同时制定一个有效的预防计划。 该项目的具体目标是，在高中卫生教室的随机对照试验中，（1）修改以技能为基础的MV、其他性病和预防怀孕课程的修改版本，使其更适合冲动决策者的需要，以便在性决策中实现预期的行为改变;（2）评估健康教室教学环境特征的影响（即，教师效能、教师直接性、价值取向和教师身份），以确定有效的教学方法和教师特征;（3）在其他班级和内容领域实施课程的强化和相关性，以促进更有效的学习材料;评估学生、教师和课程之间的互动，以确定导致持续行为改变的最佳学习环境。 这项拟议的研究将在五年内进行，涉及5 000多名学生和10至12所学校。 在前三年，将进行六项单独的干预实施研究（每年两次连续干预），六项干预研究中有五项的设计是实验性的，按学校进行随机分配。 在第4年和第5年，我们还将研究相结合的“最佳实践”基于课堂的干预措施的效果，通过比较两组学生随机学校：比较条件，以技能为基础的艾滋病毒/怀孕预防课程或最佳版本，其中包含最成功的元素测试在前三年。 分析设计将包括个人，课堂，教师和学校的水平，通过分层线性模型或其他差异测试进行评估。
