Partner‐Specific Risk Perception: A New Conceptualization of Perceived Vulnerability to STDs

Two studies were conducted to test a new conceptualization of risk perception, focusing on the risk posed by a specific sexual partner at a specific time rather than a generalized perception of vulnerability to HIV or sexually transmitted diseases. Study 1 used a cross‐sectional design and found support for a model with the following domains as antecedents of partner‐specific risk perception (PSRP): generalized perception of HIV risk, partner's sexual history, and characteristics of relationship with the partner. However, PSRP was not associated with condom use in Study 1. Study 2, which used a longitudinal design, replicated the domains predictive of PSRP and also demonstrated the influence of PSRP on condom use 4 weeks later while controlling for past condom use. The findings support the utility of this conceptualization of risk perception.
