Gender differences in trauma history and symptoms as predictors of relapse to alcohol and drug use.

The objective of this study was to determine whether there are gender-specific associations between trauma exposure and alcohol or drug relapse in alcohol-dependent adults. Participants were 51 men (n = 24) and women (n = 27) with alcohol dependence, 22 (43.1%) of whom relapsed during study participation. Severity of childhood trauma; number of lifetime events evoking fear, helplessness, or horror; and current trauma symptoms all predicted relapse in women, but not in men. These findings highlight the importance of assessing trauma history and providing treatment of trauma-related symptoms for individuals with alcohol and drug dependence, and for women in particular. © American Academy of Addiction Psychiatry.
