More information is needed to address questions that affect the design of HIV voluntary counseling and testing (VCT) services for youth. With the School of Nursing at the Muhimbili University College of Health Sciences in Tanzania, YouthNet conducted a descriptive study of youth attending VCT and other reproductive health (RH) services in Dar es Salaam, Tanzania. (RH services include sexually transmitted infections, family planning, and other services.) Using a combination of quantitative and qualitative evaluation methods, the study produced information on youth clients’ risky sexual behaviors, perceptions and intentions, and the quality of care provided by the various “youth friendly” service delivery models available in Dar es Salaam. The overall goal of this study was to provide information to policymakers to improve services at clinics providing a mix of VCT and RH services at four youth-friendly clinics in Dar es Salaam, Tanzania. To achieve this goal, the study had the following objectives: 1) To determine the risk of HIV/AIDS and unintended pregnancy among youth attending either VCT or other RH services; 2) To assess the quality of VCT and RH care offered to youth at these clinics; and 3) To document correspondence between youth’s intended and actual risk behaviors following VCT.
