Middle School Pregnancy/STD/HIV Prevention Program

Description and Explanation of Study Instrument

Barbara Marín and Cynthia Gomez at the Center for AIDS Prevention Studies at UCSF and Karin Coyle and Doug Kirby at ETR Associates developed this questionnaire as part of an evaluation study.


The questionnaire was used in a study to evaluate the impact of a middle school pregnancy/STD/HIV prevention program. The sample included students from 19 San Jose middle schools, each with a substantial percentage of Hispanic students. Students were surveyed in the 6th, 7th, 8th and 9th grades (1997-2000). The 6th grade sample included about 2,800 students; more than 80% of these students were surveyed in the 8th grade; more than 60% in the 9th grade. About half the students were in the control group and about half in the intervention group. The sample is ethnically diverse, and includes a large proportion of Hispanic students (about 50%).


The questionnaire included a large number of questions about sexuality, including questions on the following topics: existence of a boyfriend/girlfriend and age difference of that boy/girlfriend, knowledge about sexual topics, self-efficacy to avoid various sexual behaviors, norms about various sexual behaviors, perceptions of peer behaviors, opportunity to have sex, pressures to have sex, pre-coital sexual behaviors, various measures of sexual behavior, attempts to pressure someone else to have sex, and reasons to have and not to have sex.

Data from the 6th grade questionnaire have been presented in:
