BACKGROUND: MacNew is a health-related quality of life (HQOL) inventory for patients with ischaemic heart disease and includes three domains; emotional, physical and social. The MacNew gives new opportunities to compare directly patients with the three major ischaemic heart diagnoses, angina, myocardial infarction and heart failure. However, this inventory has not earlier been evaluated in Norwegian.
OBJECTIVE: The purpose of this study was to validate the Norwegian version of the disease-specific HQOL inventory MacNew by assessing the measurement model, internal consistent reliability and test-retest and convergent validity.
METHOD: Patients with ischaemic heart disease (n=124; angina pectoris, n=53; myocardial infarction, n=35; and heart failure; n=36) participated in this cross-sectional study. Patients completed the self-administered MacNew and the generic HQOL-instrument SF-36. The MacNew and the SF-36 were repeated 2-3 weeks later (test-retest) by 17 patients.
RESULTS: The psychometric properties were satisfactory to good. The construct validity assessed by factor analysis explained 61.5% of the variance. The internal consistent reliability was high (exceeded 0.90 in all domains). The test-retest analysis showed equivalent results demonstrating good reproducible properties. The convergent validity within each domain was evaluated with correlation analysis, demonstrating correlations of 0.74, 0.69 and 0.71 on the emotional, physical and social domains, respectively.
CONCLUSION: The Norwegian version of the MacNew inventory demonstrated satisfactory to good psychometric properties and can be recommended for evaluating HQOL for patients with heart diseases in clinical studies.
