Above diagonal are correlations for sample without a past-year psychological disorder; below the diagonal are correlations for sample with a past-year psychological disorder. Gender (coded 0 = Male, 1 = Female); Cigarettes/day (average number of cigarettes smoked per day in the past week); # prior quit attempts (number of “serious” lifetime quit attempts)
