title: The PedsQL in pediatric cerebral palsy: reliability and validity of the Chinese version pediatric quality of life inventory 4.0 generic core scales and 3.0 cerebral palsy module.
abstract: OBJECTIVE
  This investigation examines the reliability, validity, and sensitivity of the Chinese version Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales and 3.0 cerebral palsy (CP) Module in pediatric CP.
  
  
  METHODS
  The study sample was comprised of 126 parents of children with CP between the ages of 2 and 12 years including 18 child respondents 5-12 years of age. Mean age of the 87 boys (69.0%) and 39 girls (31.0%) was 4 years 1 month (SD 2 years 2 month).
  
  
  RESULTS
  Reliability was demonstrated for the PedsQL 4.0 (α = 0.86 child, 0.89 parent) and CP Module (α = 0.91 child, 0.96 parent). The PedsQL 4.0 distinguished between healthy children and children with CP. Construct validity of the CP Module was supported through an analysis of the intercorrelations between the Generic Core Scale scores and the CP Module Scale scores and exploratory factor analysis of PedsQL items.
  
  
  CONCLUSIONS
  The findings provide support for the measurement properties of the Chinese version PedsQL 4.0 Generic Core Scales and 3.0 CP Module in pediatric CP.
