The present study focused on predicting AIDS-preventive behavioral intentions (i. e., intentions to discuss AIDS-related information and to use condoms) from constructs taken from the health belief model, the theory of reasoned action/planned behavior, and social cognitive theory. Questionnaire data were collected from 124 undergraduates using scales from previously published work as well as some new measures designed for this study. Perceived behavioral control, perceived risk, attitudes, self-efficacy, subjective norms, negative expected outcomes, and perceived severity of HIV infection were correlated with at least one intention measure; but regression analyses showed that perceived behavioral control was the strongest independent predictor of condom use intentions and of intentions to discuss AIDS information with a partner. Implications for theory and application are discussed.
