Partner-specific risk perception: A new conceptualization of perceived vulnerability to STDs

Two studies were conducted to test a new conceptualization of risk percepti on, focusing on the risk posed by a specific sexual partner at a specific t ime rather than a generalized perception of vulnerability to HIV or sexuall y transmitted diseases. Study 1 used a cross-sectional design and found sup port for a model with the following domains as antecedents of partner-speci fic risk perception (PSRP): generalized perception of HIV risk, partner's s exual history, and characteristics of relationship with the partner. Howeve r, 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 d emonstrated the influence of PSRP on condom use 4 weeks later while control ling for past condom use. The findings support the utility of this conceptu alization of risk perception.
