Objectives: To develop a new tool to assess constraints due to urinary treatments in neurological patients.
Materials and methods: 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 3 months. 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.
Results: 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 4 min 20 s. The final version was composed by 22 items.
Conclusion: LUTS TCA is the first validated tool to assess constraints of urinary treatment and has excellent psychometric properties.
