This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The hypothesis that affective states lead to HIV risk behavior has been challenged in the literature. In reviews of the literature, Crepaz and Marks (2001; 2002) found no evidence to support the hypothesis that negative affective states such as depression or anxiety contribute to incidents of unprotected sex. In a retrospective study of HIV positive individuals, Reilly and Woo (2001) found on association between unprotected sex and self-reported depression, anxiety, or low self-esteem. The proposed research hypothesizes that the methodology employed in the studies reporting null findings -- namely, a cross-sectional methodology -- is not sensitive to daily variations in affect and their immediate sequelae. The proposed research is a pilot study for a larger study that will take place pending NIH funding. The broader research project will examine the hypothesis that stressful events are associated with increased frequency of alcohol use, sexual activity, and alcohol-involved sexual activity. The pilot study is a test of the feasibility of collecting this information from a low SES sample using a telephone-based Interactive Voice Response (IVR) system.
