Turkish Version of the Multidimensional Index of Life Quality in Patients with Acute Coronary Syndrome
Journal Title: Bezmiâlem Science - Year 2021, Vol 9, Issue 1
Abstract
Objective: Decreased quality of life is an important state in which patients with acute coronary syndrome (ACS) frequently experienced. Thus, measuring the quality of life of these patients is necessary. This study aimed to translate, cross-culturally adapt, and psychometrically test the Turkish version of the Multidimensional Index of Life Quality in patients with ACS. Methods: The study sample consisted of 370 patients with ACS who were admitted to a university hospital between October 2010 and June 2011. In this cross-sectional study, backward and forward translation methods were used between the Turkish and English version of the scale. The following psychometric properties were evaluated: content validity, exploratory and confirmatory factor analyses, Cronbach’s alpha coefficient, test–retest analysis, and equivalent forms method. Results: Goodness-of-fit index (GFI) results of the confirmatory factor analysis indicated that the a priori hypothesized nine-factor model had a non-acceptable fit in the sample based on the following: χ2=1854.58, df=523, χ2/df=3.54; p<0.001; root mean-square error of approximation = 0.09, standardized root mean residual =0.09, normed fit index (NFI) =0.81, non-NFI =0.84, GFI =0.71; adjusted GFI =0.65. The exploratory factor analysis showed six components with an eigenvalue of >1.0, explaining 69.7% of the cumulative variance. Cronbach’s alpha coefficient was 0.94 for the total scale. The test-retest analysis found significant correlation between the first and second tests of the scale (r=0.88, p<0.001). Conclusion: The findings showed that the scale can be used to determine the level of the quality of life of Turkish patients with acute coronary syndrome.
