Abstract

BACKGROUND AND PURPOSE
The Korean version of Story Memory (SM) in the Korean-Mini Mental State Examination, 2nd Edition: Expanded Version (K-MMSE-2: EV) was developed. Based on the SM, we additionally developed a full version of SM including delayed recall (DR) and recognition adding to immediate recall (IR). This study aimed to examine the reliabilities and validities of the newly developed SM in the K-MMSE-2: EV and its full version.
METHODS
Ninety-five healthy elderly individuals (HE), 90 patients with amnestic mild cognitive impairment (aMCI), and 53 patients with dementia of the Alzheimer's type (DAT) participated in the study. They were administered the full version of SM with the Seoul Verbal Learning Test-Elderly's version (SVLT-E) and Rey Complex Figure Test (RCFT). In addition, the SM was re-administered to 51 participants after a 5-week interval. Two clinical neuropsychologists independently rated the performance of 50 participants.
RESULTS
The test-retest reliabilities of the IR, DR, and recognition of the SM were statistically significant. The inter-rater reliabilities (Cohen's kappa) were high (0.87-1.00) for all the measures. The IR, DR, and recognition of SM had significant positive correlations with those of the SVLT-E and RCFT. Significant group differences in IR and DR of SM were found among the HE, aMCI, and DAT groups. The recognition scores were significantly different between the aMCI and DAT groups, but not between the HE and aMCI groups.
CONCLUSIONS
The newly developed full version of SM in the K-MMSE-2: EV was proven to be a reliable and valid memory measure for clinical use.
