Abstract:
Objective:This study aimed to find out the concordance between prescription and performance of neuropsychological tests inadults aged 90 and older.
Methods:We analyzed 270 prescriptions of patients aged 90 and older from a single hospital between 2019 and 2025, retrospectively. Prescriptions included Seoul Neuropsychological Screening Battery-Second Edition (SNSB-II), Literacy Independent Cognitive Assessment (LICA), and Korean version of the Severe Impairment Battery (SIB-K). Administration outcomes wereclassified as concordant (as prescribed), substituted (to different battery administered), simplified (just screening test and clinicalinterview), or cancelled (not administered). Floor and ceiling effects were assessed in subtests and subscales of all tests.
Results:Overall concordance rate was 52.2%. SNSB-II showed the lowest concordance (33.8%) and LICA demonstrated higher concordance (72.3%). SIB-K showed complete concordance (100%). SNSB-II completers had higher education levels thanLICA and SIB-K completers. Among subsets of SNSB-II, seven showed floor effects and three showed ceiling effects. LICA had floor effects in five and ceiling effect in one. In SIB-K, one showed floor effect and six showed ceiling effects.
Conclusion:LICA demonstrated good feasibility in this age group. These findings provide evidence for age-appropriate as-sessment protocols.
