People living with HIV/AIDS (PLWHA) who smoke are at very high risk for numerous smoking-related illnesses, but those who quit may prevent many of these illnesses. Several factors including depression, impulsivity and health have been shown to influence smoking cessation outcomes generally, but the role of these individual factors is unknown in smoking cessation among PLWHA. We examined several putative predictors of early smoking cessation among PLWHA (N = 86) who are seeking treatment in an ongoing smoking cessation trial examining the efficacy of adding contingency management to a standard treatment that includes counseling and extended release bupropion. In total, 32.6% (n = 28) of our sample consisted of treatment responders (defined as participants who had expired carbon monoxide levels of 3ppm and/or reduced urine cotinine levels at 4-weeks into treatment). Bivariate logistic regression analyses were conducted to explore the role of demographics (sex, age), smoking related factors (Fagerstrom Test of Nicotine Dependence, number of cigarettes smoked per day, Questionnaire of Smoking Urges, Minnesota Nicotine Withdrawal Scale), health (SF36 scores), depression symptoms (Beck Depression Inventory), and impulsivity (Kirby delay discounting measure) in predicting smoking cessation early treatment response (at four weeks into treatment). Perceived emotional well-being, and number of cigarettes/day predicted treatment response (p < .05).  After controlling for treatment assignment (contingency management vs. treatment as usual), smoking fewer cigarettes daily (OR = .88, 95% CI .78-.98) was the only significant predictor of better treatment response. There was a trend for emotional wellbeing (OR = .97, 95%CI .96-1.00) to also predict better early treatment response. Our analyses revealed that few variables predict early treatment response among PLWHA who are trying to quit smoking. The implications for providing smoking cessation services to PLWHA will be discussed.
