Validation of the Korean Version of the MacNew Heart Disease Health-Related Quality of Life Questionnaire

Background: Health-related quality of life (HRQoL) is an important concept in patients with cardiac diseases, including myocardial infarction (MI). Disease-specific tools offer valuable insights into the impact of a disease on various aspects of a patient’s life. Purpose: The aim of this study was to assess the psychometric properties of the Korean version of the MacNew Heart Disease HRQoL Questionnaire (Korean MacNew). Methods: One hundred thirty-six patients who had experienced MI about 3 months earlier were recruited from two tertiary hospitalsin South Korea. The internal consistency and various types of validity of the Korean MacNew were assessed. Exploratory factor analysis with varimax rotation was performed to identify a better structure for this instrument. Results: The internal consistency of the Korean MacNew was established with Cronbach’s alpha coefficients ranging from .88 to .93. Face validity and construct validity (both discriminant and concurrent) of the Korean MacNew were established. Strong positive correlations were found between the total Korean MacNew and the single-item global QoL scale (r = .73, p
