Study Summary

This study tests whether withdrawal-related cognitive deficits increase smoking relapse among HIV-infected (HIV+) vs. HIV-uninfected smokers (HIV-). Adult smokers (N=300; 150 HIV+, 150 HIV-) will complete 2 sessions to assess cognition (24h abstinence vs. smoking-as-usual; order counterbalanced; weeks 0-2). Subjects will then receive smoking cessation counseling and open label transdermal nicotine (weeks 3-12). Outcomes are: 1) cognition; and 2) abstinence rates at the end-of-treatment.

Primary Outcome

Cognitive function will be assessed at the Lab session 1 and lab session 2 visits as well as End of Treatment. Participants will complete measures of executive function, verbal learning and memory and response inhibition. The primary outcome is the change in cognitive function lab session 1, lab session 2, and End of Treatment measured by a composite score (calculated by averaging individual z-scores). Z-scores were calculated using the Stroop interference score (executive function; measured in
