RESUMO
College students commonly engage in risky sexual behaviors, such as casual sexual encounters and inconsistent condom use. Discounting paradigms that examine how individuals devalue rewards due to their delay or uncertainty have been used to improve our understanding of behavioral problems, including sexual risk. The current study assessed relations between college women's sexual partners discounting and risky sexual behavior. In this study, college women (N = 42) completed two sexual partners delay discounting tasks that assessed how choices among hypothetical sexual partners changed across a parametric range of delays in two conditions: condom availability and condom unavailability. Participants also completed two sexual partners probability discounting tasks that assessed partner choices across a parametric range of probabilities in condom availability and unavailability conditions. Additionally, participants reported risky sexual behavior on the Sexual Risk Survey (SRS). Participants discounted delayed partners more steeply in the condom availability condition, but those differences were significant only for those women with three or fewer lifetime sexual partners. There were no consistent differences in discounting rate across condom availability conditions for probability discounting. Sexual partners discounting measures correlated with risky sexual behaviors as measured by the SRS, but a greater number of significant relations were observed with the condoms-unavailable delay discounting task. These findings suggest the importance of examining the interaction of inconsistent condom use and multiple partners in examinations of sexual decision-making.
