Background: Digital transformation of conventional cognitive screening tools may improve accessibility, standardization, and objectivity. This study evaluated the validity and reliability of a tablet-based version of the Mini-Mental State Examination–Korean (MMSE-K) compared with the traditional paper-based version.
Methods: Thirty-two patients with neurological conditions (stroke, tumor, or other) were assessed using both paper- and tablet-based MMSE-K versions across two sessions. Intra- and inter-rater reliability were examined using intraclass correlation coefficients (ICCs) and Bland–Altman analyses. Convergent validity between the paper and tablet versions was also tested.
Results: The tablet-based MMSE-K showed strong agreement with the paper-based version (r = 0.89, p < .001). Intra-rater [ICC(3,1) = 0.91] and inter-rater reliability [ICC(2,1) = 0.87] were high, with Bland–Altman plots indicating acceptable agreement for total scores. Minor variability was observed in attention and comprehension domains.
Conclusions: The tablet-based MMSE-K demonstrated preliminary evidence of validity and reliability comparable to the paper version, supporting its potential use in clinical and home settings. Given the modest sample size and single-institution cohort, findings should be interpreted as preliminary, and larger multicenter studies are warranted to confirm external validity.
