A comparison of test-retest reliability of four cognitive screening tools in people with dementia.

Overall, the four screening tools were similar in test-retest reliability which imply that the MMSE, MoCA, SPMSQ, and SLUMS were reliable in monitoring cognitive function in people with dementia. The results of the direct comparisons of test-retest reliability of the four screening tools provide useful information for both clinicians and researchers to select an appropriate cognitive screening tool.Implications for RehabilitationThe MMSE, MoCA, SPMSQ, and SLUMS are equally reliable and thus they could be used to monitor the cognitive function in people with dementia.The MDC values are useful in determining whether a real change has occurred between repeated assessments for people with dementia.
