The purpose of this study is to develop and evaluate a brief, clinic-based smoking cessation treatment for an HIV+ population. We compared two treatments, a brief advice and follow-up plus nicotine patch treatment(Standard Care; SC) and brief advice and follow-up, nicotine patch, with the addition of a tailored motivational intervention and behavioral skills counseling for smoking cessation (Motivationally-Enhanced; ME), in a randomized controlled trial. We hypothesized that those HIV+ participants receiving the ME will demonstrate greater biochemically verified smoking abstinence rates at 6-month follow-up than those receiving the SC control treatment. All study participants were offered use of the nicotine patch.
