[BDSP. Notice produite par INIST-CNRS g4gWR0x6. Diffusion soumise à autorisation]. Objective. The authors used data from a larger study to evaluate the longterm effects of a peer advocate intervention on condom and contraceptive use among HIV-infected women and women at high risk for HIV infection. Methods. HIV-infected women in one study and women at high risk for HIV infection in a second study were selected from the Women and Infants Demonstration Project and assigned to a standard or an erhanced HIV prevention treatment group. The enhanced intervention includec support groups and one-on-one contacts with peer advocates tailored to clients'needs. The authors interviewed women at baseline and at 6-12-and 18-months, and measured changes in consistency of condom and contraceptive use and in self-efficacy and perceived advantages and disadvantages of condom and contraceptive use. Results. Of HIV-infected women, the enhanced group had improved consistency in condom use, increased perceived advantages of concom use, and increased level of self-efficacy compared with the standard group. Of women at risk, the enhanced intervention group at six months maintained consistent condom use with a main parther and perceived more benefit of condom use com pared with the standard group. These differences diminished at 12 months. Conclusions. The enhanced intervention was generally effective in the HIV+study, In the at-risk study, however, intervention effects were minimal and short-lived. Factors related to the theory, intervention design, and sample characteristics help explain these differences.
