Health beliefs as predictors of HIV-preventive behavior and ethnic differences in prediction.

The incidence of a variety of safer-sex behaviors was predicted, using five measures from the Health Belief Model (Janz & Becker, 1984): perceived susceptibility, perceived severity, self-efficacy, social support, and perceived barriers. The participants, 424 U.S. undergraduates at six schools, completed a written questionnaire. The results of multiple regression analyses indicated that perceived susceptibility, self-efficacy, and social support predicted many safer-sex behaviors. Although the Health Belief Model predicted more safer-sex behaviors for Euro-American students than for Hispanic American, African American, and Asian American students, the present data indicated few differences among these ethnic groups regarding the level of safer-sex behaviors.
