Alcohol-involved assault: Associations with posttrauma alcohol use, consequences, and expectancies

Victim alcohol consumption is common prior to sexual assault, and a burgeoning literature suggests that victims who were intoxicated during assault may differ in post-assault adjustment compared to those who were not impaired. Less is known about potential relationships between experiencing an alcohol-involved assault (AIA) and later drinking behavior. In this study, we examined the relationships between sexual assault, subsequent drinking behavior and consequences, and alcohol expectancies in a sample of 306 undergraduate women who reported current alcohol use and reported either no trauma history (n = 53), non-AIA (n = 69), or AIA (n = 184). Differences emerged for alcohol use (F(2, 298) = 12.78, p<.001), peak blood alcohol content (F(2, 298) = 9.66, p<.001), consequences (F(2, 296) = 7.38, p<.005), and positive alcohol expectancies (F(14, 796) = 1.93, p<.05). In particular, women with an AIA reported greater alcohol use and positive expectancies compared to women with no trauma history and women with a non-alcohol influenced assault. In addition, both assault groups reported greater drinking consequences than women with no trauma history. Findings suggest that it is the women who are assaulted while under the influence of alcohol who evidence more alcohol use and alcohol-related problems following assault. (C) 2011 Elsevier Ltd.
