Cognitive and emotional assessments of perceived risk for HIV among unmarried heterosexuals.

We examined perceived risk of contracting HIV using assessments of likelihood and worry in a probability sample of unmarried heterosexuals. Perceptions of the likelihood of contracting HIV and worry about HIV were only modestly correlated (r = .23), suggesting that they are different constructs. Far more respondents expressed worry (43%) than expressed the belief that they were at risk for HIV (9%). A significant proportion of the sample reported experiences that may have placed them at risk for HIV transmission. Demographic and psychosocial correlates of perceived likelihood and worry were examined in separate multivariate logistic analyses. Misconceptions about HIV transmission, a history of injection-drug-using sexual partners, and less education were associated with higher perceived likelihood of contracting HIV. Misconceptions, having multiple sexual partners in the past year, and a history of sexually transmitted diseases (STDs) were associated with high worry about HIV. Implications of the findings for correcting HIV-related misconceptions are discussed.
