College Women and Sexual Assault: The Role of Sex-related Alcohol Expectancies

This study examined the relationship between alcohol, sex-related alcohol expectancies, and sexual assaults among women college students. Participants completed measures of sexual behaviors, sexual victimization experiences, sex related alcohol expectancies, and drinking habits. Based on participants’ responses women were categorized as having experienced no assault, unwanted sexual contact, sexual coercion, attempted rape, and rape. It was observed across groups that relative to controls, women reporting attempted rape and rape consumed higher levels of alcohol. Within group comparisons revealed that relative to controls, victimized women endorsed higher levels of sex-related alcohol expectancies. In the prediction of severity of sexual victimization, regression analyses revealed an interaction between alcohol consumption and expectancy of vulnerability to sexual coercion. At higher levels of alcohol consumption women endorsing high vulnerability to sexual coercion experienced more severe victimatization. Implications of the findings are discussed.
