Drowning the pain: Intimate partner violence and drinking to cope prospectively predict problem drinking

Introduction: The present study examined the longitudinal association among drinking problems, drinking to cope, and degree of intimate partner violence (IPV). Two competing models were tested; the first model posited that drinking to cope leads to greater drinking problems and this subsequently leads to more violence in the relationship (an intoxication violence model). The second model speculated that violence in the relationship leads to drinking to cope, which in turn leads to greater drinking problems (a self-medication model). Methods: Eight hundred and eighteen undergraduate students at a large north-western university participated in the study over a two year period, completing assessments of IPV, alcohol related problems and drinking to cope at five time points over a two year period as part of a larger social norms intervention study. Results: Analyses examined two competing models; analyses indicated that there was support for the self-mediation model, whereby people who have experienced violence have more drinking problems later, and this association is temporally mediated by drinking to cope. Discussion: The current results are discussed in light of past research on the self-medication model. (C) 2014 Elsevier Ltd. All rights reserved.
