The study is a randomized controlled trial (RCT) pilot trial of Positive STEPS (the adapted form of the Life-Steps behavioral intervention) to improve medication adherence among HIV-infected youth. The study will allow us to demonstrate participant acceptance, ability to recruit, feasibility of intervention delivery with study counselors and all study procedures, and initial clinically significant improvement in medication adherence via MEMS caps. This research will lay the groundwork for a federal grant application for a multi-site randomized controlled intervention trial.
