Risk Perception Moderating How Knowledge is Translated into Intentions to Take Preventive Measures against Non-Communicable Diseases (NCDs)

Abstract

Risk perception is supposed to mediate between knowledge and intention. The study examines whether such a mediation also exists in the context of taking protective measures against non-communicable diseases (NCDs). Moreover, the question is raised whether health risk perception might moderate such a mechanism. A cross-sectional study was conducted. Knowledge about NCDs, intention and risk perception were assessed. A sample of 609 individuals was analyzed by hierarchical regression procedures in terms of moderated mediation. Risk perception partially mediated the knowledge-intention relationship, and risk perception components operated as a moderator. The moderator effect was positive, implying that high-risk perception in conjunction with high intention was a prerequisite for preventive measures. Low-risk perception reflects health-specific optimism, which can be a facilitator of health behavior change, in this case, the change in the intention to take preventive measures.
