Although prior studies have shown that sensation seeking and impulsive
decision-making are related to sexual risk-taking, it is still unclear whether
these personality traits operate independently or synergistically. The purpose of
this study was to elucidate the joint contribution of these personality traits to
HIV and sexually transmitted disease (STD) risk behaviors using data from a large
sample of sexually active young adults (N = 2,386). Regression modeling indicated
that both sensation seeking and impulsive decision-making were consistently
associated with sexual risk behaviors across 11 risk-related outcomes. Results
further indicated that sensation seeking and impulsive decision-making operated
synergistically with respect to the outcome variables of sex acts using drugs,
acts with a partner using alcohol, and acts with a partner using drugs. In
contrast to this, sensation seeking and impulsive decision-making operated
independently with respect to the other sexual risk outcomes. Theoretical
implications, as well as implications for HIV/STD prevention among high sensation
seekers and impulsive decision-makers, are discussed.
