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


METHODS
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.
