Influence of heavy episodic drinking on the relation between men's locus of control and aggression toward intimate partners

Abstract

Objective: This study examined the interactive effects of locus of control and heavy episodic drinking on men's physical assault and sexual coercion against intimate partners. Method: Participants were 151 heterosexual drinking men who completed self-report measures of locus of control, alcohol consumption during the past 12 months, and intimate-partner aggression during the past 12 months. Results: An internal locus of control was associated with a lower frequency of physical assault and sexual coercion toward intimate partners among men who reported lower quantities of alcohol consumption. However, data suggested that the protective qualities of an internal locus of control for both forms of partner aggression diminished among men who reported higher quantities of alcohol consumption. Conclusions: These results support alcohol myopia theory and extend this theory by suggesting how alcohol consumption may affect the relation between locus of control and different forms of intimate-partner aggression toward women.
