The Rapid Cognitive Screen (RCS) is a brief, easy to administer score screening tool for cognitive dysfunction which can be very useful for cognitive screening in busy clinical settings. We aimed to cross-culturally adapt and validate RCS in Turkish.
A total of 172 community-dwelling older participants from geriatric and neurology clinics, aged 60 and older were included. The translation and cultural adaptation process was carried out in five stages: (i) two initial translations from English to Turkish; (ii) combination of these two translations; (iii) backward translations; (iv) an expert committee that consisted of three geriatricians and two neurologists, one Turkish lecturer reviewed to compare backward translations with the English test; and (v) pretest. The inter-rater reliability and test-retest reliability were performed. To diagnose each type of dementia, gold standard diagnostic criteria specifically defined for each dementia were used. Performances of RCS test for dementia and mild cognitive impairment (MCI) were analyzed by using sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). The receiver operating characteristic analysis was performed to determine the area under the curve (AUC) with 95% confidence intervals (CI).
Among participants, 37.2% were considered as cognitively normal, 25.6% with MCI and 37.2% with dementia. The sensitivity, specificity, PPV, and NPV of RCS (cut-off point of 4) for dementia were 89.06%, 92.56%, 87.7%, and 93.5%, respectively whereas the values were 77.27%, 51.56%, 52.3%, and 76.7% for MCI with a cut-off point of 8. The RCS predicted dementia (AUC = 0.972, 95% CI: 0.935-0.991) and MCI (AUC = 0.720%, 95% CI: 0.626-0.802).
The cross-cultural adaptation was successfully achieved. The Turkish-RCS was found to be a reliable and valid test for screening of cognitive dysfunction.
快速认知筛查（RCS）是一种简短、易于实施的认知功能障碍评分筛查工具，在繁忙的临床环境中进行认知筛查非常有用。我们旨在对RCS进行跨文化改编并在土耳其语中进行验证。
纳入了172名来自老年病科和神经科门诊的60岁及以上社区居住的老年参与者。翻译和文化改编过程分五个阶段进行：（i）从英语到土耳其语的两次初始翻译；（ii）这两次翻译的合并；（iii）回译；（iv）由三名老年病学家、两名神经学家和一名土耳其语讲师组成的专家委员会进行审查，以将回译与英语测试进行比较；（v）预测试。进行了评分者间信度和重测信度测试。为诊断每种类型的痴呆症，使用了专门为每种痴呆症定义的金标准诊断标准。通过敏感性、特异性、阳性预测值（PPV）和阴性预测值（NPV）分析RCS测试对痴呆症和轻度认知障碍（MCI）的性能。进行了受试者工作特征分析，以确定曲线下面积（AUC）及其95%置信区间（CI）。
在参与者中，37.2%被认为认知正常，25.6%患有MCI，37.2%患有痴呆症。RCS（截断点为4）对痴呆症的敏感性、特异性、PPV和NPV分别为89.06%、92.56%、87.7%和93.5%，而截断点为8时，对MCI的值分别为77.27%、51.56%、52.3%和76.7%。RCS预测痴呆症（AUC = 0.972，95% CI：0.935 - 0.991）和MCI（AUC = 0.720%，95% CI：0.626 - 0.802）。
成功实现了跨文化改编。发现土耳其语版RCS是一种可靠且有效的认知功能障碍筛查测试。
