Verification of Efficacy of Cognitive Function Test Using the Cognitive Impairment Screening Test.

ABSTRACT:

Background and purpose

The Cognitive Impairment Screening Test (CIST) was developed to detect early-stage cognitive impairment. The clinical utility of this test has not yet been validated in real-world settings. This study compared the diagnostic performance of the CIST with that of the previously used screening test (PST).

Methods

We used research data from the ANSYS database of the National Institute of Dementia, Republic of Korea. Individuals who underwent screening tests between 2017 and 2023 were analyzed. Scores were compared among participants stratified by age, sex, and education duration. The discriminative performance of both screening tests in detecting cognitive impairment was assessed. The equipercentile equating method was used to enable score conversion betwe
