This study assessed the interpretability of changes in Qualiveen, a specific health-related quality-of-life (HRQOL) questionnaire for urinary disorders (UD) in multiple sclerosis (MS) patients. Qualiveen has 30 items focusing on four aspects of patients' lives related to their urinary problems: bother with limitations (nine items), frequency of limitations (eight items), fears (eight items), and feelings (five items). Response options are framed as 5-point Likert-type scales, and scores on each domain range from 0 to 4.
