Preliminary evaluation of Croatian version of the non-motor symptoms scale in Parkinson’s disease

Non-motor symptoms (NMS) of Parkinson’s disease (PD) are common and have a great impact on PD patients. They are often under-recognized and remain untreated. The non-motor symptoms scale (NMSS) is an instrument specifically designed for the comprehensive assessment of NMS in PD patients. The objective of this study was to preliminary evaluate the psychometric properties of Croatian version of the NMSS as an instrument for measuring NMS in Croatian-speaking PD patients. In this research was analysed data on 23 PD patients, which included 8 women and 15 man which underwent neurological care at Clinical Hospital Centre Osijek in Croatia. Our research problem was examined using the NMSS which includes nine domains: cardiovascular including falls, sleep/fatigue, mood/cognition, perceptual problems/hallucinations, attention/memory, gastrointestinal tract, urinary, sexual function and miscellaneous. The data was descriptively analysed and Chronbach’s α coefficient assessed internal consistency. Pearson r correlations were performed on the nine domains of the NMSS. The level of significance was set to p < 0.05. The mean age was 70.8±10.4 years, and mean disease duration was 6.5±4.2 years. The mean NMSS score was 112.70±60.89, where the more common non-motor symptoms in PD patients were related to the following domains: mood/cognition (21.64%), sleep/fatigue (18.86%), sexual function (14.93%) and urinary (12.51%). Cronbach’s α coefficient for the NMSS total score using the entire sample was 0.93, indicating high internal consistency. For domains, the Cronbach’s α coefficient ranged from 0.43 to 0.97. The total NMSS score was highly correlated with each of the nine domains, the Pearson r correlation coefficient ranged from 0.43 to 0.78. This preliminary results suggests that Croatian version of NMSS can be considered a comprehensive and reliable measure for NMS in Croatian-speaking PD patients.
