The purpose of this study is to develop and evaluate a school-based HIV, STD, and pregnancy prevention program for 7th and 8th grade middle school students using a randomized-controlled intervention trial. The intervention program consists of a classroom-based curriculum and an interactive CD-ROM. Ten middle schools were recruited to participate in this intervention trial. Five middle schools were randomized to the intervention group; and five middle schools were randomized to the control group. The study is also developing a model for obtaining community support for the development of HIV, STD and pregnancy prevention programs for middle school youth.
