防護動機理論に基づくエイズ予防行動意図の規定因の検討

抄録

According to the revised protection motivation theory (Rogers, 1983), it was assumed that the decision to engage (or not engage) in a health-related behavior is determined by seven cognitive factors: perceived severity, perceived probability of the occurrence, intrinsic and extrinsic rewards, response efficacy, self-efficacy, and response costs. In order to explore the determinants of HIV preventive intentions based on the theory, 398 Japanese university students (212 men and 186 women) were asked to rate these cognitive factors and three intentions of HIV prevention acts. As predicted, self-efficacy had positive contributions to all three intentions. Perceived probability of occurrence and response efficacy had positive contributions to one or two of the intentions, whereas intrinsic rewards and extrinsic rewards had negative contributions to one of the intentions. Severity and response costs, however, had no contribution to any intention. The above results partially supported the protection motivation theory.
