The long-term goal of this research program is to disseminate an effective, brief computer-based intervention that can be readily integrated into community-based, HIV treatment settings to motivate tobacco quitline use among smokers living with HIV. The overall objective of this application, which is the first step in the attainment of our long-term goal, is to develop this computer-based intervention, modify it based on initial piloting and feedback to insure its feasibility and acceptability, and obtain preliminary data supporting the efficacy of the intervention. The rationale for the proposed research is that many smokers living with HIV are interested in quitting smoking, and that by exploring their smoking-related concerns, providing feedback and enhancing self-efficacy, they can become motivated to engage in smoking cessation counseling, utilizing a no-cost, readily available treatment option-their local tobacco quitline. We plan to accomplish the objective of this application by pursuing the following three specific aims:
