Recent data suggests Qualiveen has excellent validity in French-speaking multiple sclerosis (MS) patients. Aim: To assess discriminative measurement properties of the English version of Qualiveen. Methods: Fifty-five Canadian MS out-patients completed a set of questionnaires, including Qualiveen, MSQOL-54, a MS-specific HRQL questionnaire, urinary function assessments and the Expanded Disability Status Scale (EDSS) twice at an interval of two to four weeks. Results: Qualiveen proved internally consistent (Cronbach's alpha coefficients 0.73 to 0.90 for the four Qualiveen domains) and test-retest reliable (intraclass correlation coefficients 0.88 to 0.94). Consistent with a priori predictions, we found a strong association between overall Qualiveen score and the degree of incontinence (0.63), a moderate correlation with the type of urinary symptoms (0.49), a weak association with manner of voiding (0.28) and weak or absent correlations with MSQOL-54 domains, EDSS bladder/bowel and global EDSS. Predictions proved generally accurate (weighted kappa = 0.65). Conclusion: The internal consistency, test-retest reliability and cross-sectional construct validity of the English version of Qualiveen are excellent, and similar to the original French version. Further studies should explore Qualiveen's longitudinal validity and responsiveness. Langue : ANGLAIS Tiré à part : OUI |
