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. 2024-03-18T10:38:05Z 2024-03-18T10:38:05Z 2023-01 info:eu-repo/semantics/article 2330-1619 http://hdl.handle.net/10259/8840 10.1002/mdc3.13658 2330-1619 eng Movement Disorders Clinical Practice. 2023, V. 10, n. 4, p. 586-595 https://doi.org/10.1002/mdc3.13658 http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 Internacional International Parkinson and Movement Disorder Society
