Reliability and validity of a chronic care facility adaptation of the Clinical Dementia Rating scale

Int J Geriatr Psychiatry. 2001 Aug;16(8):745-50. doi: 10.1002/gps.385.

Abstract

Objective: This study investigated the reliability and validity of a chronic care facility adaptation of the Clinical Dementia Rating scale (CDR-CC).

Method: Sixty-two residents in a chronic care facility participated in an inter-rater and 1 month test-retest reliability study. The instrument was validated against the Mini-Mental State Examination (MMSE).

Results: Inter-rater and 1 month test-retest reliability for the global CDR-CC score were excellent (intraclass correlation coefficients 0.99 and 0.92, respectively). The CDR-CC domain and global scores were negatively correlated with the MMSE.

Conclusions: The CDR-CC is a global assessment tool that reliably and validly measures cognitive and functional impairment in a chronic care setting.
