Abstract

To reduce deaths due to nose and throat cancer, also known as nasopharyngeal cancer (NPC), it is important to understand factors that motivate the public to undertake cancer screening. This study employed the risk perception attitude (RPA) framework to predict factors influencing NPC risk-reducing behaviors among a group of Malaysians. A sample of Malaysians (n=215) completed a questionnaire about perceived susceptibility, perceived severity, self-efficacy, response efficacy, and intention to enact self-protective actions to reduce NPC risk. A majority of the participants had responsive (high risk, high efficacy) and proactive attitudes (low risk, high efficacy). Hierarchical regression of mediation effect under structural equation model (SEM) approach was used to test the theory. Response efficacy and self-efficacy were negatively associated with perceived risk (p<0.01). Intention was negatively associated with perceived risk and positively associated with response efficacy and self-efficacy (p<0.01). Heightened perceived risk weakens efficacy beliefs and intention to enact self-protective behavior, suggesting that low-risk messages may work better to avert fatalistic thinking for this group. Perceived risk and response efficacy explained 26.5% of the variance in self-efficacy, suggesting the importance of framing NPC risk messages to heighten the audience’s confidence to enact self-protective health behaviors.
