title: Psychometric properties of the coronary heart disease scale of the quality-of-life instruments for chronic diseases (QLICD-CHD): an application to Cantonese patients.
abstract: The purpose of this study was to validate the applicability of our proposed disease-specific questionnaire to Cantonese coronary heart disease (CHD) patients. During the investigation from August 2010 to March 2012, 1000 Cantonese inpatients were recruited. The reliability of the scale was judged by the internal consistency, and the content and construct validity were assessed by using Pearson correlation and confirmatory factor analysis, respectively. Results showed that the Cronbach's α coefficient for the whole scale and most domains/facets were larger than .70 (.59 to .93). Most items had moderate to strong Pearson correlations with their respective facets (r > 0.50). Confirmatory factor analysis showed that the indices for goodness of fit were nearly acceptable. Overall, the QLICD-CHD scale has adequate psychometric properties when applied to Cantonese CHD patients.
