title: Transcultural adaptation and validation of the Korean version of Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILD).
abstract: OBJECTIVE
  The aim of this study was to translate and transculturally adapt the Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILD) questionnaire into Korean language, and to test the reliability and validity, including the internal consistency, known-group validity and factor analysis of the Korean version of the CPCHILD.
  
  
  METHODS
  A Korean version of CPCHILD was produced according to internationally accepted guidelines. For validity testing, 194 consecutive parents or caregivers of children with cerebral palsy (CP) were recruited and completed the questionnaire. Internal consistency, test-retest reliability, and known-groups validity were evaluated and factor analysis was performed to validate the Korean version of the CPCHILD.
  
  
  RESULTS
  In terms of internal consistency, a Cronbach's alpha was above 0.90 in all domains of the CPCHILD (range 0.921 to 0.966), except the 5th domain (0.628). In terms of known-groups validity, the total score of the CPCHILD was significantly different according to the Gross Motor Function Classification System (GMFCS) level (p < 0.001). Intra-class correlation coefficient spanned from 0.517 to 0.801. Factor analysis showed that the five-factor solution of the CPCHILD explained 76.7% of the variance with 59.0, 6.5, 5.1, 4.2 and 3.2% of variance by each components number.
  
  
  CONCLUSIONS
  The Korean version of CPCHILD was found to be a reliable and valid questionnaire of caregivers' perspectives on the health-related quality of life in severely affected children with CP. However, the Korean version of CPCHILD contains some redundant items, and factor analysis suggested a five-domain questionnaire. Implication for Rehabilitation The Korean version of CPCHILD is a reliable, internally consistent, valid instrument for assessing the health-related quality of life in severely affected children with CP from the perspective of caregivers. After the transcultural adaptation and validation of the Korean CPCHILD, it can be reliably used in clinical and research settings to evaluate the health-related quality of life in Korean patients with CP.
