Daily process studies of internal drinking motives have not examined motive specificity, i.e., whether theoretically plausible trait and situational antecedents differ in their ability to predict the extent to which alcohol consumption on any given day is motivated by coping or enhancement.
University students (N=81) completed trait measures of coping and enhancement-motivated drinking (trait CM and EM), sensation seeking, and conscientiousness, and then completed a 14-day online diary assessing daily completion of tasks, daily alcohol use, and (on days when alcohol was consumed) the extent to which drinking was motivated by coping or enhancement (daily CM and EM).
Hierarchical linear models revealed unique situational and trait antecedents of daily CM and EM. In the daily EM drinking model, main effects of daily positive affect (b=0.11, p
