Brief summary

This research is studying behaviors that young people engage in that may place them at risk for contracting a sexually transmitted disease like HIV/AIDS, and what kind of educational program works best to reduce these risky behaviors.

Detailed description

During baseline assessment, a computer questionnaire is administered, including questions about participants' attitudes, beliefs, and behaviors regarding sexual behavior, condom use, and drug use. A saliva sample is provided as well. A Time-Line Follow-Back is conducted, noting on which days certain activities occurred, such as sexual intercourse, alcohol use, marijuana use, and cigarette use. A urine sample is also collected in order to test for the STD's chlamydia and gonorrhea (if results are positive, we schedule a meeting with the participant to administer medication to treat the STD). In the second session, a 3-hour interventional health class is held with groups of same-gender participants. There are 3 different health classes (one focusing just on sex risk reduction, one focusing on sex and alcohol risk reduction, and one focusing on sex, alcohol, and marijuana risk reduction); participants are randomly assigned to one. Participants are contacted 3 months after the intervention, 6 months after, 9 months after, and 12 months after, in order to meet. These meetings entail completing another Time-Line Follow-Back and completing another questionnaire. At the final 12 month meeting, we collect another urine sample to again test for chlamydia and gonorrhea. As before, if results are positive, we schedule a meeting with the participant to administer medical treatment.
