The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), widely used for detecting cognitive impairment in different neuropsychiatric conditions, is increasingly applied for measuring cognitive functioning in older individuals. Available normative data for RBANS Italian version suffer from under-representation of the older ages (>60 years) and are not corrected for education. Moreover, normative data are provided only for Indexes and Total scores. We thus administered RBANS Italian version in a larger sample of older adults, taking into account the effect of age, education and gender on all scores.
We used a regression-based model to assess the effect of age, education, and gender on RBANS Subtests, Indexes and Total scores in a consecutive series of healthy cognitively normal volunteers aged 60-79 years (N = 158). The obtained norms were compared with the Italian original normative data by means of Wilcoxon rank-sum test.
Multiple linear regression analyses showed that age and educational level significantly influence performances on most RBANS scores. A free-to-use Excel to calculate subject's percentiles for any single score was developed. When compared with original normative values, our percentiles distribution of Indexes and Total scores did not reveal significant differences (p > .05).
The obtained normative data show good concordance with previous norms. The instrument seems not significantly affected by educational level. The possibility to correct for any single score could make RBANS a more precise measure for capturing subtle cognitive deficits in prevention studies.
用于评估神经心理状态的可重复性成套测验（RBANS）广泛应用于检测不同神经精神疾病中的认知障碍，越来越多地用于测量老年人的认知功能。RBANS意大利语版本现有的常模数据存在老年人群（>60岁）代表性不足的问题，且未对教育程度进行校正。此外，仅提供了指数和总分的常模数据。因此，我们在更大样本的老年人中施测了RBANS意大利语版本，同时考虑了年龄、教育程度和性别对所有分数的影响。
我们使用基于回归的模型，评估年龄、教育程度和性别对连续一系列年龄在60 - 79岁的健康认知正常志愿者（N = 158）的RBANS子测验、指数和总分的影响。通过Wilcoxon秩和检验将获得的常模与意大利语原始常模数据进行比较。
多元线性回归分析表明，年龄和教育水平对大多数RBANS分数的表现有显著影响。开发了一个免费使用的Excel程序来计算任何单个分数的受试者百分位数。与原始常模值相比，我们的指数和总分百分位数分布没有显著差异（p > 0.05）。
获得的常模数据与先前的常模显示出良好的一致性。该工具似乎不受教育水平的显著影响。能够校正任何单个分数可能使RBANS在预防研究中成为更精确的测量细微认知缺陷的方法。
