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.

In this study we examined multiple partners in a household probability sample of heterosexuals. Thirty-seven percent reported 2 or more partners in the past year, and 6% reported 5 or more partners. Significant interactions among gender, ethnicity, and relationship status revealed complex relations. African American men without a primary partner were the most likely to have multiple partners; ethnic minority women with primary partners were the least likely. Psychosocial factors associated with multiple partners were examined with the AIDS Risk Reduction Model (ARRM). Situational factors influenced how ARRM variables related to multiple partners. Perceived risk, commitment to monogamy, and communication were all important correlates. Prevention efforts must focus on increasing awareness of the risks of heterosexual transmission of HIV for people in dating relationships and on strengthening sexual communication skills with new partners.

We examined correlates of condom use among heterosexual whites, blacks, and Hispanics (ages 20-45 years) with an human immunodeficiency virus (HIV) risk factor in a community-based longitudinal sample (San Francisco; n = 716). Lag models were used to examine hypothesized antecedents of condom use at wave 2. High levels of condom use were associated with labeling one's sexual behavior as risky for HIV infection, high levels of condom enjoyment and commitment to use condoms, good sexual communication practices, gender (trend), and marital status. The results support the need for wide-ranging intervention programs that stimulate people to make personal risk assessments, teach basic sexual skills, and direct those in need of intensive help to appropriate agencies.
