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. Copyright © 2001 John Wiley & Sons, Ltd.
