title: Reexamining the Factor structure of somatization using the children's somatization inventory (CSI-24) in a community sample.
abstract: OBJECTIVE
  Pediatric somatization studies have used the 35-item Child Somatization Inventory (CSI-35) or psychometrically refined 24-item CSI (CSI-24). Exploratory factor analysis of the CSI-24 has identified a single factor that did not show good model fit in confirmatory factor analysis (CFA). Further evaluation of the CSI-24 factor structure is needed.
  
  
  METHODS
  The present study examined alternative factor structures of the CSI-24 in a community sample (N = 233, ages 8-15).
  
  
  RESULTS
  The CFA showed good fit for a single CSI-24 factor, better fit for multiple factor models, and best fit for a single, six-item factor. Construct validity for that factor was found in significant correlations with anxiety, depression, functional disability, and quality of life.
  
  
  CONCLUSIONS
  Results are consistent with a single somatization factor, but research is needed to verify the factor structure in different, race/ethnic/demographic, and clinical groups.
