Individuals perceptions of coronary heart disease (CHD) have implications for the ways in which they respond to the disease, process risks, make decisions, and take action to reduce CHD risks. This study aimed to develop and evaluate the psychometric properties of the perceptions of coronary heart disease scale (PCS) among a Hong Kong Chinese population. A cross-sectional study was conducted using a convenient sample (n = 232) of participants recruited from a variety of catchments including public domains, a cardiac unit, and a cardiac rehabilitation and prevention center. Exploratory factor analysis identified a nine-item, two-factor model that accounted for 52.5% of the total explained variance. The two factors were the perceived risk (five items) and perceived seriousness (four items) of CHD. The PCS demonstrated good content validity; acceptable total, and subscale internal consistency (.73,.61-.81); and significant contrast-group differences with higher levels of CHD perceptions among males (p =.002), younger participants (p <.001), and those with higher educational levels (p <.001), suggesting excellent construct validity. The newly developed PCS demonstrates acceptable psychometric properties as a short measurement scale, which supports its use in future research. Future validation of this scale is warranted.
