Launched in 2004 in Burkina Faso, Ghana, Malawi, and Uganda, to provide detailed information on adolescent risk-taking and health-seeking behavior as related to HIV, STDs and unintended pregnancy. Examined a range of factors (e.g., behavioral, sociocultural, economic) that could lead to increased vulnerability of risk. Also encompassed knowledge of means of prevention, sources of trusted information and health care, and impediments to adolescents' abilities to apply their knowledge and take preventive action.
