Description
Summary:	Multiple sclerosis (MS) is a chronic progressive disease of the central nervous system that results in a wide range of clinical manifestations and has a great impact on patient health-related quality of life (HRQoL). The aim of this study was to determine the psychometric properties of the Croatian version of the Multiple Sclerosis International Quality of Life (MusiQoL) questionnaire. In this research was analysed data of 82 MS patients (51 women and 31 man, average 42.6±11.9 years) which underwent neurological care at Clinical Hospital Centre Osijek, Croatia. Our research problem was examined using the multidimensional and self-administrated MusiQoL questionnaire. The data was descriptively analysed and internal consistency reliability was assessed by Chronbach’s alpha coefficient. Pearson’s correlation was performed on the MusiQoL index score and dimension scores of the MusiQoL questionnaire. The level of significance was set to p<0.05. Cronbach’s alpha for the MusiQoL total score using the entire sample was 0.93, indicating a high internal consistency. Also, all MusiQoL dimensions demonstrated a high internal consistency (Chronbach’s alpha: 0.75-0.95). The MusiQoL index score significantly correlated with all MusiQoL dimension scores (Pearson’s correlation: 0.43-0.86). The Croatian version of the MusiQoL questionnaire can be a valid and reliable instrument for measuring QoL in Croatian-speaking MS patients and constitutes a useful instrument to measure HRQoL in the clinical setting.
