MIRANDA, David et al. Validación del "Michigan Hand Outcomes Questionnaire" para población colombiana. Rev.Colomb.Reumatol. [online]. 2008, vol.15, n.4, pp. 271-290. ISSN 0121-8123.
Purpose: to validate the Michigan Hand Outcomes Questionnaire for its use in Colombian clinical population: to translate and adapt the scale in order to obtain a cross-linguistically equivalent version in Spanish, and to assess the reliability, sensitivity to change, and content and construct validity of the Colombian Spanish version. Methods: observational study to validate a scale in 205 Colombian patients of plastic surgery, rehabilitation, and rheumatology in a University Hospital, who had a hand disorder. Results: the principal component analysis showed six domains, as in the original questionnaire, but the content of some of them differed from the original MHQ scales. We assessed internal consistency of the entire 37-item original scale, and Cronbachs alpha was of 0,92. All scales had good test-retest reproducibility, except for the Pain scale. Upon evaluation of the results of the scale three and six months after its first application, significant differences could be observed in the total score as well as in the scores for each of the scales. Conclusions: the Colombian Spanish version of Michigan Hand Outcomes Questionnaire has good reliability, validity, and sensitivity to change. Assessment of internal consistency indicated that the scale could be reduced and its psychometric properties would possibly improve.
