Overview

Aim: Multiple sclerosis has a major impact on the quality of life of the patient. The aim of the study was to validate the Multiple Sclerosis Quality of Life Questionnaire – 54 (MSQOL-54) linguistically and culturally. The instrument includes a wide range domain of quality of life which is related with health. Methodology: Principal component analysis with orthogonal Varimax rotation was used to assess the construct validity. Preliminary analysis was performed using the Kaiser Meyer-Olkin statistic and Bartlett‘s test of sphericity. For the analysis of the factor structure of the instrument we used the procedures of confirmatory factor analysis. Results: In the pilot study there were 104 respondents. The reliability of the whole questionnaire confirmed the value of Cronbach a = 0.979. The most significant correlations were found between the Expanded Disability Status Scale scores: pain and physical health (P < 0.001). Statistically significant inverse correlations were found between duration of disease and MSQoL-54 subscales at the P < 0.001 level in the areas: task limitation due to emotional problems, energy, cognitive functions, sexual activity, change in health status, and satisfaction with sexual activity. Conclusion: The questionnaire shows possibilities of use in a larger sample of respondents without limitation to the diagnosed type of multiple sclerosis and with extended items in the area of sociodemographic screening, level of self-care and mental health.
