Psychometric properties of the Icelandic version of the MacNew heart disease health-related quality of life questionnaire

The MacNew is designed to estimate patient’s feelings on how ischemic heart disease (IHD) affects every day functioning. The MacNew has proven to be a well-equipped tool for measuring Health-Related Quality of Life (HRQOL) in numerous languages and its psychometric properties evaluated with affirmative results. In this study the psychometric properties of the Icelandic version of the MacNew were tested. Participants were 164 heart disease patients (120 men and 44 women, age ranging from 36 to 85 years (M = 61.7, SD = 9.6)) that went through four weeks of cardiac rehabilitation. Participants answered four self-report measures (MacNew, B-IPQ, DASS and SF-36) before and after the rehabilitation in addition to 32 participants that answered again, two weeks later for the test-retest assessment. The internal reliability of the MacNew proved to be good, Cronbach´s = .92. A two factor solution was confirmed, KMO = .90 and the Bartlett´s test of sphericity, 2 (351) = 2113.32, p < .001. The test-retest reliability of the globalscore ( = .87, p < .001) and subscales = .83 - .87, p < .001) proved to be adequate. A paired sample t-test indicated that the MacNew was sensitive to change. The results showed that the psychometric properties of the Icelandic version of the MacNew satisfied reliability criteria and are confirmed.
