Notes.: Will = willingness to drink; Int = intentions to drink; Anx = trait anxiety; Dep = depressive symptoms; PA = positive affect. Model fit indices are based on examination of Akaike information criterion (AIC) and Bayesian information criterion (BIC) for k = 3, 4, and 5 knots. Smaller values indicate better fit. Values with an asterisk (*) indicate best model fit (i.e., final chosen model).
