Considerations
- Although this test has been used for many years it has not been further analyzed in recent years, and would benefit from more recent analysis.
- This test would benefit from further testing to configure the MDC, SEM, and MDIC.
- This test appears to be most responsive with people who have significant signs and symptoms of dementia which would suggest this is the most appropriate population for this test.
- Axes I through IV can be administered multiple times in the same day for continuous measurement. Axis V requires a resting interval of several days between administration for appropriate scoring (Reisberg & Ferris, 1988).
- Axis V showed differing inter-rater reliability when administered by physicians compared to non-physicians in a long term care facility. Due to the influence of psychiatric and physical illness on this axis, physicians are likely more able to appropriately assess this axis (Foster et al., 1988).
Older Adults and Geriatric Care
back to PopulationsNormative Data
Community dwelling older adults with dementia and nursing home dwelling older adults with dementia: (Cohen-Mansfield & Taylor, 1998; senior daycare center participants, n = 195, mean age = 80; nursing home dwelling participants, n = 408, mean age = 85)
