title: Daily associations between anxiety and alcohol use: variation by sustained attention, set shifting, and gender.
abstract: Many theories of emotion regulation and alcohol use posit that alcohol is consumed as a way to regulate negative mood. However, the literature has conflicting evidence on mood-alcohol use associations. Understanding how individual differences affect mood-alcohol use associations remains an important area of study. Previous research has suggested that cognitive abilities may affect the relationship between mood and alcohol. The current ecological momentary study examined associations between daytime anxious and positive mood and both (a) the likelihood of alcohol use and (b) the intensity of use on drinking nights as a function of sustained attention, set shifting, and gender. Participants (n = 100) completed assessments of sustained attention and set shifting, then carried palmtop computers for 21 days, reporting mood and alcohol use up to 8 times per day. Results showed that positive mood was consistently associated with both likelihood and intensity of alcohol use, but the association between positive mood and alcohol outcomes was not affected by cognitive abilities. Anxious mood was positively associated with the likelihood of drinking for men with high cognitive abilities. Anxious mood was positively associated with intoxication on drinking nights for men with high sustained attention, but inversely associated with intoxication on drinking nights for women with high sustained attention. Results suggest that variation in mood, executive functioning, and gender interact to contribute to observed differences in drinking behavior. These differences may be the result of gender-specific coping strategies in response to negative emotion.
