Abstract

OBJECTIVE: We investigated trait and alcohol-specific self-control as unique predictors and moderators of the relation between implicit drinking identity associations and drinking.
METHOD: Three hundred undergraduates completed a drinking identity Implicit Association Test (IAT), trait and alcohol self-control questionnaires, and alcohol consumption, problems, and cravings inventories.
RESULTS: Regression analyses tested for unique effects of predictors and for Self-Control × IAT interactions. Each predictor accounted for unique variance in consumption, but there was no evidence of moderation effects. Both types of self-control, but not IAT scores, accounted for unique variance in problems. A Trait Self-Control × Implicit Drinking interaction accounted for excess zeros in problems, with a greater likelihood of not having alcohol problems among individuals with low implicit identity who had higher versus lower trait self-control. Each predictor accounted for unique variance in cravings. A Trait Self-Control × IAT interaction was also found, indicating that implicit drinking identity was a stronger predictor of cravings among those with lower versus higher trait self-control.
CONCLUSIONS: Results are partially consistent with previous research: Both types of self-control and drinking identity associations predicted unique variance in drinking, and moderation effects were observed for trait self-control and drinking identity associations and two of the three drinking variables.
FINDINGS suggest that trait and alcohol-specific self-control and implicit drinking identity could be useful intervention targets. (J. Stud. Alcohol Drugs, 75, 290-298, 2014).
