Abstract
To develop a new tool to assess constraints due to urinary treatments in neurological patients. A prospective, monocentric study has been conducted from January to May 2017. Out-patients (multiple sclerosis, spinal cord injury, Parkinson disease) were included in a referral center if they had LUTS treatment for at least 3months. To validate psychometric properties, we conducted a literature review, qualitative interviews, and discussion with a panel of six experts. Comprehension, acceptation, and pertinence were tested by a pilot study. A validation study, designed to calculate content validity, internal consistency reliability, and test-retest reliability [intraclass correlation coefficient (ICC)] has been conducted. The primary outcome was good psychometric properties defined with Cronbach's α>0.7 and ICC>0.7. Comprehension, acceptation, and pertinence were excellent. Validation study showed a perfect content validity (r2 = 1) and excellent internal consistency reliability (Cronbach' α=0.90). Total score was between 0 (best score) to 66 (maximal constraints). Test-retest reliability calculated using ICC was 0.81. Time to fill questionnaire was 4min 20s. The final version was composed by 22 items. LUTS TCA is the first validated tool to assess constraints of urinary treatment and has excellent psychometric properties.
