Correlation between the Folstein Mini-Mental State Examination and Three Methods of Clock Drawing Scoring

Abstract

The objective of this study was to assess the correlation between (1) the Folstein Mini-Mental State Examination (MMSE) score and three methods of clock drawing scoring and (2) three methods of clock drawing scoring them selves. A convenience sample of consecutive community-dwelling seniors and attendees at a referral seniors clinic in a tertiary care hospital was used. One hundred fifty participants (72 women, 78 men) were seen with an aver age age of 76 years. There was a significant correlation (P = .01) between MMSE scores and all three methods of clock drawing (R = .67, .618, -.498, respectively), as well as among the three methods of clock drawing scoring. The clock drawing scores showed good correlation with the MMSE score. The clock drawing is well accepted (by the patient) and easily administered (by the health care provider). Clock drawings are recommended as the minimum requirement for cognitive assessment of elderly patients in busy primary care practices and can be used to high light those patients requiring additional cognitive testing.
