ABSTRACT

Objective. To determine the metric properties of the non-motor symptoms questionnaire (NMSQuest), non-motor symptoms scale (NMSSS) and SCOPA-AUT clinimetric instruments to assess non motor dysfunction in Mexican population. Material and methods. After linguistic validation, the instruments were applied to 100 consecutive Parkinson’s disease patients to analyze its metric properties in Mexican out-patients from the National Institute of Neurology and Neurosurgery. Results. Internal consistency by Cronbach’s alpha was above 0.80 for all instruments. Inter-item and item-total correlations were above 0.30 in the majority of the domains and inter-observer variability was acceptable. Total score did not correlate with any of the registered clinical variables. Conclusion. The metric properties of the three instruments were acceptable and similar to published data from other countries.
