The Korean Repeatable Battery for the Assessment of Neuropsychological Status-Update : Psychiatric and Neurosurgery Patient Sample Validity

Abstract

This study aimed to validate the Korean version of the Repeatable Battery for the Assessment of Neuropsychological Status Update (K-RBANS). Methods : We performed a retrospective analysis of 283 psychiatric and neurosurgery patients. To investigate the convergent validity of the K-RBANS, correlation analyses were performed for other intelligence and neuropsychological test results. Confirmatory factor analysis was used to test a series of alternative plausible models of the K-RBANS. To analyze the various capabilities of the K-RBANS, we compared the area under the receiver operating characteristic (ROC) curves (AUC). Results : Significant correlations were observed, confirming the convergent validity of the K-RBANS among the Total Scale Index (TSI) and indices of the K-RBANS and indices of intelligence (r=0.47-0.81; p<0.001) and other neuropsychological tests at moderate and above significance (r=0.41-0.63; p<0.001). Additionally, the results testing the construct validity of the K-RBANS showed that the second-order factor structure model (model 2, similar to an original factor structure of RBANS), which includes a first-order factor comprising five index scores (immediate memory, visuospatial capacity, language, attention, delayed memory) and one higher-order factor (TSI), was statistically acceptable. The comparative fit index (CFI) (CFI, 0.949) values and the goodness of fit index (GFI) (GFI, 0.942) values higher than 0.90 indicated an excellent fit. The root mean squared error of approximation (RMSEA) (RMSEA, 0.082) was considered an acceptable fit. Additionally, the factor structure of model 2 was found to be better and more valid than the other model in χ 2 values (Δχ 2 =7.69, p<0.05). In the ROC analysis, the AUCs of the TSI and five indices were 0.716-0.837, and the AUC of TSI (AUC, 0.837; 95% confidence interval, 0.760-0.896) was higher than the AUCs of the other indices. The sensitivity and specificity of TSI were 77.66% and 78.12%, respectively. Conclusion : The overall results of this study suggest that the K-RBANS may be used as a valid tool for the brief screening of neuropsychological patients in Korea.

Effect of Anti-Aging Standard Forest Healing Program With Multiple Visits to a Forest Facility on Cognition in Older Age Patients

“…The K-RBANS evaluates five domains (attention, language, visuospatial/construction, immediate recall, and delayed recall). 14 15 Higher scores on both the CIS and K-RBANS indicate better cognitive function. In this study, K-RBANS was assessed at baseline, 12 weeks, and 20 weeks.…”

Efficacy of a Mobile-Based Multidomain Intervention to Improve Cognitive Function and Health-Related Outcomes Among Older Korean Adults with Subjective Cognitive Decline

“…The Korean version of the mini-mental state examination, 2nd edition (K-MMSE-2), was used as a secondary outcome. The reliability and validity of both instruments had been statistically demonstrated in numerous studies involving community-dwelling older adults [ 28 , 29 ].…”

A Study on Verification of Equivalence and Effectiveness of Non-Pharmacologic Dementia Prevention and Early Detection Contents : Non-Randomly Equivalent Design

“…The K-RBANS [ 21 ] is an independent and concise examination of attention, language ability, visuospatial/constructional ability, and immediate and delayed memory. This test consists of 12 subtests and is designed to allow skilled examiners to conduct the test for approximately 20 to 30 minutes.…”

“…The RBANS, which consists of 12 subtests and takes approximately 20 to 30 minutes when conducted by an experienced examiner, is an individual simple test that measures attention, language, visual space composition ability, immediate memory, and delayed memory [ 22 ]. The K-RBANS [ 21 ], standardized for the Korean population, was conducted with the examiner using test papers, targeting individuals between 12 to 60 years or older. Standard scores were collected from 606 healthy adolescents and adults using stratified sampling.…”
