Smoking and suicidal ideation among college students: Smoking expectancies as potential moderators

Document Type


Publication Date



In the present study, we sought to establish a link between suicidal ideation (SI) and smoking in college students, determine whether psychopathology accounted for the association, and determine whether smoking expectancies were moderators. Participants ( = 607) were identified as nonsmokers, exsmokers, infrequent smokers, or daily smokers. Participants were assessed for smoking patterns, smoking expectancies, psychopathology, SI, and past suicide attempts. Daily smokers had the highest level of SI. There was a dose-response relationship between smoking and SI, such that the higher the daily smoking rate, the greater the SI, even when controlling for depression, alcohol use, and drug use. Trend-level results indicated that at lower smoking rates, elevated smoking-related negative affect reduction (NAR) expectancies were associated with lower SI, while elevated NAR expectancies in combination with higher smoking rates were associated with greater SI. Smoking cessation programs for college students should screen for SI.
