 Outreach workers will be placed at 9 primary care pediatric and family medicine practices throughout one urban area. Adolescent patients at these 9 practices will be identified and then randomized into two groups; 1 those receiving outreach intervention during Year 1 of the study and 2 those receiving outreach intervention during Year 2 of the study. Randomization will be stratified by practice site, patient age, and patient gender.
