The aim of this study was to verify the equivalence and effectiveness of the tablet-administered Korean Repeatable Battery for the Assessment of Neuropsychological Status (K-RBANS) for the prevention and early detection of dementia.
Data from 88 psychiatry and neurology patient samples were examined to evaluate the equivalence between tablet and paper administrations of the K-RBANS using a non-randomly equivalent group design. We calculated the prediction scores of the tablet-administered K-RBANS based on demographics and covariate-test scores for focal tests using norm samples and tested format effects. In addition, we compared the receiver operating characteristic curves to confirm the effectiveness of the K-RBANS for preventing and detecting dementia.
In the analysis of raw scores, line orientation showed a significant difference (t=-2.94, p<0.001), and subtests showed small to large effect sizes (0.04-0.86) between paper- and tablet-administered K-RBANS. To investigate the format effect, we compared the predicted scaled scores of the tablet sample to the scaled scores of the norm sample. Consequently, a small effect size (d≤0.20) was observed in most of the subtests, except word list and story recall, which showed a medium effect size (d=0.21), while picture naming and subtests of delayed memory showed significant differences in the one-sample t-test. In addition, the area under the curve of the total scale index (TSI) (0.827; 95% confidence interval, 0.738-0.916) was higher than that of the five indices, ranging from 0.688 to 0.820. The sensitivity and specificity of TSI were 80% and 76%, respectively.
The overall results of this study suggest that the tablet-administered K-RBANS showed significant equivalence to the norm sample, although some subtests showed format effects, and it may be used as a valid tool for the brief screening of patients with neuropsychological disorders in Korea.
本研究旨在验证用于痴呆预防和早期检测的平板电脑版韩国可重复神经心理状态评估量表（K-RBANS）的等效性和有效性。
使用非随机等效组设计，对88例精神病学和神经病学患者样本的数据进行检查，以评估平板电脑版和纸质版K-RBANS之间的等效性。我们根据人口统计学和焦点测试的协变量测试分数，使用常模样本计算平板电脑版K-RBANS的预测分数，并测试格式效应。此外，我们比较了受试者工作特征曲线，以确认K-RBANS在预防和检测痴呆方面的有效性。
在原始分数分析中，线条方向显示出显著差异（t=-2.94，p<0.001），纸质版和平板电脑版K-RBANS之间的子测试显示出小到中等的效应量（0.04-0.86）。为了研究格式效应，我们将平板电脑样本的预测量表分数与常模样本的量表分数进行了比较。因此，除了单词列表和故事回忆显示中等效应量（d=0.21）外，大多数子测试中观察到小效应量（d≤0.20），而图片命名和延迟记忆子测试在单样本t检验中显示出显著差异。此外，总量表指数（TSI）的曲线下面积（0.827；95%置信区间，0.738-0.916）高于五个指数的曲线下面积，范围为0.688至0.820。TSI的敏感性和特异性分别为80%和76%。
本研究的总体结果表明，尽管一些子测试显示出格式效应，但平板电脑版K-RBANS与常模样本显示出显著等效性，它可能被用作韩国神经心理障碍患者简短筛查的有效工具。
