Selected Grants:
Understanding Health Risk in the Context of Adolescent Development
- Role: Principle Investigator
- Dates: 2006 – 2011
- Funder: National Institutes of Health
- Description: This research focused on advancing a developmental understanding of adolescent relationships, sexual decision-making, and sexual behavior, and the implications of these developmental changes for HIV and pregnancy prevention. This developmental understanding is a necessary component to the uptake and effectiveness of any adolescent prevention program.
Understanding Reproductive Health Risk of a Community-based Sample of Adolescent Boys
- Role: Principle Investigator
- Dates: 2010 – 2011
- Funder: National Institutes of Health
- Description: Furthering previous work on developmental understanding of reproductive health risk of a community-based sample of adolescent boys. This work demonstrated the strengths of mixed methods approaches (qualitative data, quantitative survey data, and biomarker data) in identifying and elucidating the mechanisms by which adolescent development influences HIV and pregnancy risk. It describes the attitudes and expectations leading to sexual risk, and the predictors of adolescent behaviors, including poorly understood aspects of sexual decision-making, such as sexual initiation, and difficult to intervene phenomenon such as condom non-use in established relationships. Much of this work was done with community-based samples.
