title: Reliability and validity of the Turkish King's Health Questionnaire in women with urinary incontinence.
abstract: OBJECTIVE
  The aim of this study was to translate the King's Health Questionnaire (KHQ) into Turkish and to test its reliability and validity among Turkish women with urinary incontinence (UI).
  
  
  METHODS
  Three hundred and thirty-five women with symptoms of UI completed the Turkish versions of the KHQ, short forms of the Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7), and the Incontinence Severity Index (ISI). Psychometric analysis of the KHQ included assessments of test-retest reliability, internal consistency, construct, and criterion validity. Factor analysis was used to explore the underlying structure of the KHQ.
  
  
  RESULTS
  The internal consistency (Cronbach's alpha ≥0.68) and test-retest reliability of the KHQ were found to be high (p < 0.001). Interdomain correlation analysis showed good convergent validity among Role, Physical, and Social Limitations, with relatively higher correlations and divergent validity between Personal Relationships and other domains, with relatively lower correlations. Exploratory factor analysis identified three factors, namely, Daily Life and Emotions, Personal Relationship, and General Health Perception. The KHQ was also significantly correlated with IIQ-7, UDI-6, and ISI (p < 0.01).
  
  
  CONCLUSIONS
  The results suggest that the Turkish KHQ is a valid and reliable condition-specific quality of life instrument for Turkish women with UI.
