Significant values are given with boldface emphasis. CPSD = cigarettes per smoking day, mFTQ = modified Fagerström Tolerance Questionnaire, SP = social phobia, CES-D = Center for Epidemiologic Studies Depression Scale, NA = negative affect.

aGender was dummy coded with 0 = female, 1 = male.

bSP group was coded 0 = average SP symptoms, 1 = high SP symptoms.

*P < .05; **P < .01.
