Prospective Risk for Incapacitated Rape Among Sexual Minority Women: Hookups and Drinking.

Sexual minority women (SMW), including lesbian and bisexual women, are at greater risk for heavy drinking and sexual victimization than heterosexual women. Risk factors for alcohol-related sexual victimization, such as incapacitated rape (IR), include frequent heavy drinking and hookups among heterosexual women, but it is less clear whether these risk factors extend to SMW. This current study was designed to address this gap. In a national sample of SMW (N = 1,057), logistic regressions were used to test whether heavy drinking and hookups in the first year of the study were risk factors for IR during the second year. After controlling for history of prior sexual victimization, subsequent IR was predicted by an interaction between heavy drinking and the number of male hookup partners. Specifically, more frequent heavy drinking was associated with increased risk for subsequent IR, but only among SMW who reported more than one male hookup partner, indicating exposure to more potential perpetrators. When examined separately, this finding held for bisexual women, but was not significant for lesbian women, likely because they reported fewer male hookup partners. Overall, findings from this longitudinal study highlight that in combination, heavy drinking and hookups with multiple men elevate risk for IR.
