STUDY DESIGN: Descriptive Psychometrics Study OBJECTIVES: Neurogenic lower urinary tract dysfunction (NLUTD), or "neurogenic bladder" is a common and disruptive condition for individuals with spinal cord injury (SCI) and disease (including multiple sclerosis, MS). Our team has developed patient-centered instruments of urinary symptoms specific to patients with NLUTD, across bladder management methods. Validity evidence is needed to support the use of two new instruments, Urinary Symptom Questionnaires for people with Neurogenic Bladder (USQNB) for those who manage their bladder with indwelling catheters (IDC), or who void (V).
SETTING: Online surveys completed by individuals in the United States with NLUTD due to either SCI or MS who manage their bladder with indwelling catheters (SCI, n = 306; MS, n = 8), or by voiding (SCI, n = 103; MS, n = 383). A total of n = 381 USQNB-IDC respondents (five control groups), and 351 USQNB-V respondents (four control groups), contributed to our convergent and divergent validity evidence.
METHODS: Data were collected online to estimate key aspects of psychometric validity (content, reflection of the construct to be measured; face, recognizability of the contents as representing the construct to be measured; structural, the extent to which the instrument captures recognizable dimensions of the construct to be measured). Divergent and convergent validity evidence was derived from multiple control groups, while evidence of criterion validity was derived from attribution of each item to their experience "with a UTI".
RESULTS: Evidence of face, content, criterion, convergent, and divergent validity was compiled for each instrument.
CONCLUSIONS: The instruments demonstrate adequate, multi-dimensional, validity evidence to recommend their use for decision-making by patients, clinicians, and researchers.
