Project PLUS tests an HIV risk reduction/adherence behavioral intervention with HIV-infected individuals in Connecticut prisons. Participants are randomly assigned to one of three groups: prior to release from incarceration (Group 1), after release from incarceration (Group 2), and treatment-as-usual (Group 3). We hypothesize that the intervention groups (Groups 1 & 2) will demonstrate significantly greater knowledge regarding drug- and sex- related HIV risk behavior and HIV medication adherence, greater motivation to reduce HIV risk behavior and improve HIV medication adherence, and enhanced skills for engaging in HIV risk reduction behavior and HIV medication adherence vs. the treatment-as-usual group. We will also compare these outcomes between Groups 1 and 2.
