The HIV Data

Description

These data come from the Voluntary HIV Counseling and Testing Efficacy Study (2000a,b), conducted in 1995-1997, by the Center for AIDS Prevention Studies, University of California, San Francisco. This study was concerned with the effectiveness of HIV counseling and testing in reducing risk behavior for the sexual transmission of HIV. As part of this study, respondents were surveyed about their attitude toward condom use via a bank of 15 items. Respondents were asked how much they agreed with each of the statements on a 4-point response scale.
