title: Validation of a Spanish version of the Childhood Health Assessment Questionnaire.
abstract: OBJECTIVE
  To determine the reliability and validity of a Spanish version of the Childhood Health Assessment Questionnaire (CHAQ).
  
  
  METHODS
  Fifty-five patients with juvenile rheumatoid arthritis (JRA) [35 girls, 20 boys; mean age at onset (+/- SD) 11 +/- 3.3 yrs, mean disease duration 3.3 +/- 2.2 yrs] were included in an observational and cross sectional study that evaluated translation validity, cross sectional construct validity, and test-retest reliability of the Spanish version of the CHAQ. The questionnaire was administered to either patients or one of their parents, and results were correlated with the Steinbrocker functional class, the Juvenile Arthritis Functional Assessment Scale (JAFAS), and disease activity.
  
  
  RESULTS
  The mean CHAQ score (mean 0.77, range 0.01-2.25) was found to correlate at different levels with Steinbrocker functional class (r = 0.62, p < 0.0001), JAFAS (r = 0.65, p < 0.0001), and disease activity score (r = 0.40, p < 0.0001). Test-retest and interobserver agreement had good correlations.
  
  
  CONCLUSIONS
  The Spanish version of the CHAQ we studied is a reliable and valid tool for assessment of health status in Spanish speaking children with JRA.
