Notes.: Will = willingness to drink; Int = intentions to drink; PA = positive affect; NA = negative affect; Dep = depressive symptoms; Anx = trait anxiety; Max eBAC = maximum estimated blood alcohol content. ICC = intraclass correlation coefficient (i.e., ratio of between-person variance to total variance; 1 - ICC = ratio of within-person variance total variance). Values with an asterisk (*) are statistically significant (p <.05) between high and low median split groups of the same variable (based on independent samples t-tests).
