Abstract

The discipline of behavioral economics integrates principles from psychology and economics to systematically characterize decision-making preferences. Two forms of behavioral economic decision making are of relevance to HIV risk behavior: delay discounting, reflecting preferences for immediate small rewards relative to larger delayed rewards (i.e., immediate gratification), and probability discounting, reflecting preferences for larger probabilistic rewards relative to smaller guaranteed rewards (i.e., risk sensitivity). This study examined questionnaire-based indices of both types of discounting in relation to sexual risk taking in an emergency department sample of hazardous drinkers who engage in risky sexual behavior. More impulsive delay discounting was significantly associated with increased sexual risk-taking during a drinking episode, but not general sexual risk-taking. Probability discounting was not associated with either form of sexual risk-taking. These findings implicate impulsive delay discounting with sexual risk taking during alcohol intoxication and provide further support for applying this approach to HIV risk behavior.
