Self-control and smoking in a sample of adults living with HIV/AIDS: A cross-sectional survey.

Introduction: Cigarette smoking prevalences are very high in persons living with HIV (PLWH). Identifying variables among PLWH that are linked to smoking in community samples (e.g., self-control) can inform smoking treatments for PLWH. The current study examined the association of self-reported self-control and smoking (e.g., smoking status, cigarette dependence) in a sample of PLWH.

Methods: Adult PLWH were recruited from the Center for Positive Living (Montefiore Medical Center, Bronx, New York, US). All participants completed measures of demographics, cigarette smoking, and self-control. Participants who reported current cigarette smoking completed measures of cigarette dependence; intolerance for smoking abstinence; and motivation, confidence, and desire to quit smoking.

Results: The overall sample included 285 PLWH (49.1% cigarette users, 55.4% male, 52.7% Black race, 54.8% Latino/a ethnicity). PLWH with current cigarette smoking reported lower self-control than PLWH with no current cigarette smoking (M = 116.88, SD = 17.07 versus M = 127.39, SD = 20.32; t = -4.15, df = 211, p < 0.001). Among PLWH with current cigarette smoking, lower self-control was associated with greater cigarette dependence (ρ = -0.272, p < 0.01), and lower confidence in quitting smoking cigarettes (ρ = 0.214, p < 0.05). Lower self-control was associated with greater overall smoking abstinence intolerance (ρ = -0.221, p < 0.05) and withdrawal intolerance (ρ = -0.264, p < 0.01).

Discussion: Among a sample of PLWH, lower self-control was related to cigarette smoking (versus no smoking), greater cigarette dependence, lower confidence in quitting smoking, and greater intolerance for smoking abstinence. It may be useful to target self-control among PLWH to increase confidence in quitting and abstinence intolerance with the goal of improving smoking cessation outcomes.
