 This study will consist of three phases. The first phase will address the first two goals by conducting repeated, in-depth interviews and discussions with a small group of sexually active adolescents in India and Tanzania, followed up by interviews with informants and relevant community members. These interviews and discussions will address differences in HIV risk characteristics between groups of women and the legal, social, cultural, and delivery factors hindering womens participation in microbicide trials. The second phase will consist of a series of workshops to define and describe a set of youth-friendly procedures for using microbicides. Community members and researchers will participate in these workshops, and some adolescents will be invited to pretest the study instruments.
