Abstract: (497 Views)
Aims: This study aimed to investigate the psychometric properties of the Multiple Sclerosis International Quality of Life (MusiQoL) questionnaire for Croatian-speaking MS patients.
Instrument & Methods: This descriptive study was conducted in 2024 at Clinical Hospital Centre in Osijek, Croatia. Eighty-two patients with multiple sclerosis (MS) participated in the study (51 female and 31 male, mean age 42.6±11.9 years). The instrument used in this study was the MusiQoL questionnaire, which was translated into Croatian language using the forward-backward translation method. The data was descriptively analyzed. Cronbach’s α internal consistency coefficient and test-retest analyses were conducted for reliability. Pearson’s correlation coefficient (r) was used to analyze the relationship between the MusiQoL index and dimensions. Exploratory factor analysis was conducted to test construct validity.
Findings: The mean for the MusiQoL index was 64.18±17.13, while the dimension scores ranged from 54.73±28.12 to 84.05±18.85. High internal consistency was found for the MusiQoL index (α: 0.93). All dimensions of the MusiQoL showed high internal consistency (α: 0.75-0.95). The intra-class correlation coefficient of the MusiQoL dimensions and MusiQoL index were 0.949-0.971 and 0.911, respectively. There was a moderately strong relationship between the MusiQoL index and dimensions (r: 0.43-0.86). Bartlett's significance test of the correlation matrix is high and significant (χ2=2028.41; p<0.001). The Kaiser-Meyer-Olkin coefficient was calculated as 0.801. The extracted factors explained 66.10% of the variance, and the range of factor loading was 0.52-0.90.
Conclusion: The Croatian version of the MusiQoL questionnaire is valid and reliable for measuring the quality of life among Croatian-speaking MS patients. It is especially useful for measuring health-related quality of life in clinical practice.
