Hazardous alcohol use and intimate partner violence in the military: Understanding protective factors.

Hazardous alcohol use is a well-established risk factor for men's intimate partner violence (IPV), with dozens of studies demonstrating the association. The current study extends understanding of the hazardous alcohol use-IPV link by examining what factors moderate this association in a more systematic and broader way that has been done in past studies. Individual, family, workplace, community, and developmental factors were tested as moderators of the hazardous alcohol use and IPV link in a large, representative sample of active duty service members (the 2006 Community Assessment), and the results were tested for replicability in a hold-out sample. Two family variables (relationship satisfaction and parent-child satisfaction), 1 community variable (community safety), and 3 developmental variables (years in the military, marital length, and family income/pay grade) cross-validated as significant moderators of the association between men's hazardous alcohol use and IPV. Across the significant moderators, the association between hazardous alcohol use and men's IPV was weakened by maturation/development, improved community safety, and better relationship functioning. No individual or workplace variables were significant moderators for men, and there were no significant moderators found for women. The results support the importance of a developmental and relational perspective to understanding the hazardous alcohol use-IPV link, rather than solely an individual coping perspective.
