Psychometric testing of the Chinese Mandarin version of the MacNew Heart Disease Health-related Quality of Life questionnaire for patients with myocardial infarction in mainland China.

Abstract

Tools to measure the quality of life of Chinese myocardial infarction (MI) patients in mainland China are small in numbers. For this study, 210 Chinese patients with MI were recruited to examine the psychometric properties of the Chinese Mandarin version of the MacNew Heart Disease questionnaire. Thirty-five participants managed to complete the retest after 2 weeks. The MacNew Heart Disease questionnaire had acceptable internal consistency, test-retest reliability and concurrent validity. The principal components analysis identified three factors which accounted for 56.6% of the variance. The MacNew Heart Disease questionnaire demonstrated good reliability and validity to be used as a health status measurement tool, and is ready for clinical use in the assessment of the quality of life of Chinese MI patients in mainland China.
