Update, translation, cross-cultural adaptation, and validation of Nottingham Stroke Dressing Assessment into Spanish

Abstract The Nottingham Stroke Dressing Assessment (NSDA) is a scale for assessing the ability and independence to dress people who have suffered a stroke. The objective of this study was to update the original scale and create its Spanish version. The NSDA scale was reviewed, translated, cross-culturally adapted, and validated. A standardised multi-step translation and updating protocol was implemented to achieve optimal conceptual and semantic equivalence and validate it. The Spanish version was validated in 110 stroke survivors. The exploratory analysis generated 12 factors. Internal consistency was satisfactory (α = 0.92). Intra-rater reliability was high (ICC = 0.92). The correlation between the ENVI-R and the FMA was demonstrated and significant (r = 0.34–0.5). The updated, translated, and culturally validated Spanish version of this scale can be used reliably and validly in research and clinical practice after demonstrating adequate and significant psychometric properties. The use of these scales will improve the quality of stroke-dressing assessment and allow for reliable comparisons.
