ADS = Alcohol Dependence Scale; CPSD = Cigarettes per Smoking Day; DPDD = Drinks per Drinking Day; Employ. = Employment; FTND = Fagerström Test for Nicotine Dependence. R2 change, unstandardized regression coefficients, and standard errors presented for each block. Results presented are from reduced models excluding blocks that were not significant (“---” indicates nonsignificant block where block coefficients were not considered further).
