title: Cognitive change checklist:  psychometric characteristics in community-dwelling older adults.
abstract: OBJECTIVE
  To extend the psychometric study of the Cognitive Change Checklist (3CL) by examining the reliability, factor structure, and external correlates of 3CL informant and self-report ratings in community-dwelling adults. We also conducted receiver operating characteristic analyses examining rating scores from this normative sample with those of clinical samples.
  
  
  METHODS
  Scale reliability and validity study.
  
  
  METHODS
  Community sites.
  
  
  METHODS
  Six hundred seventy-nine older adults.
  
  
  RESULTS
  The pattern of scale relationships within and across versions, and the failure to find associations with age and education, were consistent with findings in clinic samples reported previously. Factor analysis replicated the four-factor structure of the informant ratings. All informant version scales significantly discriminated amnestic mild cognitive impairment cases and patients with mild dementia from normals.
  
  
  CONCLUSIONS
  These findings provide support for the use of the checklist as a clinical tool to facilitate identification of cases of mild cognitive impairment and early dementia.
