Generalizing behavioral findings across times, samples, and measures: A study of condom use

Data from a Knowledge, Attitude, Belief, and Practices (KABP) Survey, administered to a sample of residents of Saint Vincent and the Grenadines, were used to replicate a previous study (Fishbein, Trafimow, Francis, et al., 1995) that investigated the relative importance, as predictors of condom use, of selected theoretical variables from the theory of reasoned action (Fishbein & Ajzen, 1975), and the theory of planned behavior (Ajzen & Madden, 1986). Besides addressing generalization problems, the study tested a more internally valid formulation of the role of past behavior that supported the argument that past condom use is better viewed as a predictor of current intention than as a criterion variable. Perhaps more important, the influence of past behavior was found to be partially mediated by its effect on attitudes and norms.
