The Cognitive Abilities Screening Instrument (CASI) has a score range of 0 to 100 and provides quantitative assessment on attention, concentration, orientation, short-term memory, long-term memory, language abilities, visual construction, list-generating fluency, abstraction, and judgment. Scores of the Mini-Mental State Examination, the Modified Mini-Mental State Test, and the Hasegawa Dementia Screening Scale can also be estimated from subsets of the CASI items. Pilot testing conducted in… 

Test-retest reliability and minimal detectable change of the Cognitive Abilities Screening Instrument in patients with dementia

Clinicians and researchers should be cautious while using these four domains to explain score changes between repeated assessments of patients with dementia, as four domains demonstrated lower ICC values and substantial random measurement errors.

Ecological, convergent, and discriminative validities of the cognitive abilities screening instrument in people with dementia

The CASI has adequate ecological validity, good convergent validity, and acceptable discriminative validity in people with dementia, and the 5 domains with nonsignificant differences or ceiling effects should only be used with caution to distinguishPeople with dementia.

Since cognitive abilities are influenced by education, and there are high rates of illiterate or low education individuals among the elderly in Taiwan, the normative data of CASI, including its total score and its cognitive domain scores, should be divided into different education ranges.

Improving the Screening Power of the Cognitive Abilities Screening Instrument, Chinese Version

It is shown that an alternative scoring system, i.e., a weighted sum of the scores from the 9 domains in the CASI C-2.0, may improve its effectiveness in screening and short-term memory and orientation appeared to be the 2 most relevant domains and their combined score was shown to be more effective than the total score in screening dementia.

Cutoff Scores of the Cognitive Abilities Screening Instrument, Chinese Version in Screening of Dementia

The purpose of this study of dementia screening was to obtain different cutoff scores of the Cognitive Abilities Screening Instrument, Chinese versions (CASI C-2.0) for subjects with different educational backgrounds, namely those who had no formal education, received 1–5 years of schooling, and received 6 or more years of education.

The applicability of the cognitive abilities screening instrument–short (CASI-S) in primary care in Brazil

The CASI-S can be useful for dementia screening in primary care in Brazil, and its internal consistency, test-retest stability, and diagnostic accuracy are analyzed.

Performance on the Cognitive Abilities Screening Instrument at Different Stages of Alzheimer’s Disease

This study validates the usefulness of the CASI for assessing the severity of dementia and found that the domain scores differed in their relative usefulness for detecting dementia and for distinguishing in different levels of dementia.

The Clock Drawing Test versus Mini-mental Status Examination as a Screening Tool for Dementia: A Clinical Comparison

This review looks at the most commonly used tests in dementia screening, namely, the clock drawing test (CDT) and the mini-mental status examination (MMSE), which have been the subject of scrutiny of various studies, reviews, and meta-analysis.

Measurement Equivalence between the Original and Estimated Mini-Mental State Examination in People with Dementia

The estimated MMSE score was found to have moderate to excellent equivalence to the originalMMSE score, and the three domains with moderate equivalence should be used cautiously to interchange with the original MMSE in people with dementia.
