Note. N = 338 (sample sizes vary across analyses Ns = 326–338 due to missing data). BDI-II = Beck Depression Inventory—Second Edition; FTND = Fagerström Test for Nicotine Dependence; RFS = Reasons for Smoking Scale; SCQ = Smoking Consequences Questionnaire.

^aCronbach's α estimate of respective smoking variable.

^bBeta weight for regressor variable in an individual model including only that regressor variable after adjusting for age, gender, ethnicity, current anxiety disorder, current alcohol abuse/dependence, current drug abuse/dependence, and history of somatic disease.

**p < .01, ***p < .001, †p < .0001, nonsignificant findings are not displayed.
