Note. All cross-lagged difference score models were adjusted for age, age squared, sex, race, education, income and wealth. Number of drinks/week at baseline and follow-up were natural log transformed. Number of observations was 14,283 for each cross-lagged difference score models.
N = Neuroticism; E = Extraversion; O = Openness; A = Agreeableness; C = Conscientiousness. RMSEA = root mean square error of approximation; SRMR = standardized root mean square residual; CFI = comparative fit index.
