This research study evaluates the efficacy of an abstinence-only intervention in preventing sexual involvement in young adolescents. Dr. Jemmott et al. randomly assigned 662 African American students in grades 6 and 7 to an 8-hour abstinence-only intervention, an 8-hour safer-sex-only intervention, or an 8-hour health-promotion control group.
The results showed that abstinence-only intervention reduced sexual initiation and recent sexual intercourse. None of the interventions had significant effect on consistent condom use or unprotected intercourse.
Although other studies in the past have reported intervention-induced reductions in sexual intercourse among adolescents, this is the first randomized controlled trial that demonstrates a reduction in the percentage of adolescents who reported any sexual intercourse for 24 months after intervention. The article concludes that theory-based abstinence-only interventions may have an important role in preventing adolescent sexual involvement.

This fact sheet discusses the use of technology in the process of behavioral interventions to promote positive practices as way to reduce the transmission of HIV/AIDS. These computer technology-based measures are individually tailored, can be interactive videos, and group targeted. The success rates of these computer-based intervention measures were discussed, how these interventions work in a rural context, internet-based interventions, and how to develop internet-based interventions.
- “Comparison of the impact of computer technology-based interventions with previously tested human-delivered interventions generally revealed similar effects of these two intervention types.” (p. 2)
- “[In terms of internet-based interventions], many of these types of interventions may show promise in terms of innovative HIV prevention strategies, but strong evaluation data on these approaches are not yet available.” (p. 2)
- “Interventions were most efficacious when: 1) they targeted a single gender (rather than both genders), 2) they used individualized tailoring and a stages of change model, 3) they included multiple intervention sessions.” (p. 2)
