Bladder-related quality of life in people with neurological disorders: reliability and validity of the Turkish version of the King’s Health Questionnaire in people with spinal cord injury

The study aimed to evaluate the reliability and validity of the Turkish version of the King's Health Questionnaire (KHQ) for individuals with spinal cord injury (SCI). It also sought to compare bladder-related quality of life between SCI and multiple sclerosis (MS) patients. The KHQ, a questionnaire assessing the impact of urinary incontinence on quality of life, was translated into Turkish and administered to SCI and MS patients, along with other questionnaires (Qualiveen and SF-36) for comparison. The results indicated that the Turkish KHQ is a reliable and valid tool for assessing bladder-related quality of life in SCI patients. SCI patients reported poorer bladder-related quality of life compared to MS patients.

• 1
  The Turkish version of the KHQ demonstrated high internal consistency (Cronbach’s alpha: 0.68-0.93) and test-retest reliability (intraclass correlation coefficient: 0.69-0.94) in patients with SCI.
• 2
  A significant correlation was found between the KHQ sub-scales and the majority of the sub-scores of the Qualiveen scale (p<0.05).
• 3
  Patients with SCI had significantly higher (worse) scores in some KHQ subscales (incontinence impact, social limitations, emotional problems, incontinence severity, and symptom severity) compared to MS patients (p<0.05).
