Changing behavior to prevent STDs/AIDS

There is a growing body of evidence that theory-based behavioral interventi ons can effectively reduce risky behaviors that can lead to the acquisition and transmission of STDs/HIV. Despite the substantive uniqueness of any gi ven behavior, there are only a limited number of theoretical variables that need to be considered in any attempt to produce behavior change. These var iables are identified and two multi-site studies are described to illustrat e how these variables can be used to guide the development of effective beh avior change interventions in both community and clinic settings.
