title: Assessing health-related quality of life in children with recurrent headache: reliability and validity of the PedsQLTM 4.0 in a pediatric headache sample.
abstract: OBJECTIVE
  To evaluate the reliability and validity of a commonly used measure of health-related quality of life (HRQOL), the Pediatric Quality of Life Inventory (PedsQL 4.0), in a sample of children with a recurrent headache syndrome.
  
  
  METHODS
  Participants were 40 children aged 7-12 who completed measures of HRQOL, headache-related disability, and headache activity during a baseline period and following a self-directed cognitive-behavioral intervention.
  
  
  RESULTS
  The data are supportive of the reliability (internal consistency and test-retest) and validity (criterion related, convergent, known-groups, and responsiveness to intervention) of the PedsQL 4.0 within a pediatric headache sample.
  
  
  CONCLUSIONS
  We conclude that the PedsQL 4.0 is a reliable and valid measure of HRQOL in children with recurrent headache and captures important information not routinely evaluated in chronic pain populations.
