Drinking motives for self and others predict alcohol use and consequences among college women: the moderating effects of PTSD.

Although drinking motives have been shown to influence drinking behavior among women with trauma histories and PTSD, no known research has examined the influence of drinking motives on alcohol use and alcohol-related consequences for women with PTSD as compared to women with a trauma history but no PTSD and women with no trauma history. Therefore, the present study sought to examine the associations between drinking motives women held for themselves as well as their perception of the drinking motives of others and their own alcohol use and consequences, and whether this was moderated by a history of trauma and/or PTSD. College women (N=827) were categorized as either having no trauma exposure (n=105), trauma exposure but no PTSD (n=580), or PTSD (n=142). Results of regression analyses revealed that women with trauma exposure and PTSD consume more alcohol and are at greatest risk of experiencing alcohol-related consequences. A diagnosis of PTSD moderated the association between one's own depression and anxiety coping and conformity drinking motives and alcohol-related consequences. PTSD also moderated the association between the perception of others' depression coping motives and one's own consequences. These findings highlight the importance of providing alternative coping strategies to women with PTSD to help reduce their alcohol use and consequences, and also suggest a possible role for the perceptions regarding the reasons other women drink alcohol and one's own drinking behavior that may have important clinical implications.
