To be designated an“OfficialMDS translation,”the confirmatory factor analysis Comparative Fit Index had to be≥0.90.ResultsResults:The Spanish MDS-NMS was tested in 364 native-Spanish-speaking patients with PD from sevencountries. For all subjects with fully computable data with all domains of the MDS-NMS (n=349), theComparative Fit Index was≥0.90 for the nine eligible domains. Missing data were negligible and moderateflooreffect (42.90%) was found for the Non-Motor Fluctuations subscale. Item homogeneity coefficient wasadequate, and the correlation of the MDS-NMS domains with other measures for related constructs wasacceptable (rs≥0.50).ConclusionsConclusions:The Spanish version of the MDS-NMS followed the IPMDS Translation Program protocol, reachedthe criterion to be designated as an Official Translation, and is now available on the MDS website. 2330-1619 http://hdl.handle.net/10259/8840 10.1002/mdc3.13658 2330-1619 Non-motor symptoms Rating scale Parkinson’s disease Expanded and Independent Spanish Validation of the MDS‐Non Motor Rating Scale
