Application of the PTSD-alcohol expectancy questionnaire (P-AEQ) to sexually assaulted college women

Risk of alcohol use problems is an important clinical concern for women who have been sexually assaulted and experience PTSD symptoms. This study explored this risk by testing a factor structure of an alcohol expectancy questionnaire that assesses beliefs about alcohol's effects on posttraumatic stress symptoms (P-AEQ). Symptom-specific expectancy scores were then tested as predictors of alcohol consumption. Subjects were 96 female undergraduate women who reported being forced to have sex, 68 who experienced pressure to have sex, and 149 who denied any forced or pressured sex.

Findings supported a role for posttrauma symptom-specific al...
