The Oxford Cognitive Screen (OCS) is a screening tool for the assessment of poststroke deficits in attention, memory, praxis, language, and number processing. The goal of the present study was to develop a Russian version of the OCS (Rus-OCS) via translation of the original battery, its cultural and linguistic adaptations, and reporting preliminary findings on its psychometric properties.
All parts of OCS were translated by native Russian-speaking neuropsychologists. Russian-speaking stroke patients (N = 205) were assessed with the Rus-OCS. Their performance was compared with performance of 60 healthy Russian-speaking adults aged between the ages of 18 and 91 years. The performance of 15 stroke patients and 42 healthy adults were assessed with a parallel version within 7 days of first testing. Convergent validity of the Rus-OCS was established via correlations with comparable tasks. Performance of three stroke groups with different lesion lateralization (right, left, and bilateral) was compared on language and visual attention subtasks. Preliminary normative data based on 5th to 95th percentile were also reported.
Measures of internal consistency and test-retest reliability ranged from acceptable to very good and estimates of convergent validity ranged from moderate to high. Sensitivity and specificity was found to range from .56 to 1 and from .73 to 1, respectively. Significant differences in performance between stroke and healthy groups on all subtasks confirmed the discriminative power of the Rus-OCS was good.
Rus-OCS is a promising cognitive screening instrument for Russian-speaking patients. However, further validation is needed. Constraints of socioeconomic differences between Russian speakers in the wider population should be considered. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
牛津认知筛查量表（OCS）是一种用于评估中风后注意力、记忆力、实践能力、语言能力和数字处理能力缺陷的筛查工具。本研究的目的是通过对原始量表进行翻译、文化和语言调适，并报告其心理测量特性的初步结果，来开发俄语版的OCS（Rus-OCS）。
OCS的所有部分均由以俄语为母语的神经心理学家进行翻译。使用Rus-OCS对以俄语为母语的中风患者（N = 205）进行评估。将他们的表现与60名年龄在18至91岁之间的以俄语为母语的健康成年人的表现进行比较。在首次测试后的7天内，使用平行版本对15名中风患者和42名健康成年人的表现进行评估。通过与可比任务的相关性来确定Rus-OCS的收敛效度。比较了三个具有不同病变侧化（右侧、左侧和双侧）的中风组在语言和视觉注意力子任务上的表现。还报告了基于第5至第95百分位数的初步常模数据。
内部一致性和重测信度的测量结果从可接受到非常好，收敛效度的估计值从中等到高。发现敏感性和特异性分别在0.56至1和0.73至1之间。中风组和健康组在所有子任务上的表现存在显著差异，证实了Rus-OCS具有良好的区分能力。
Rus-OCS是一种有前景的针对以俄语为母语患者的认知筛查工具。然而，需要进一步验证。应考虑更广泛人群中说俄语者的社会经济差异限制。（PsycINFO数据库记录（c）2019美国心理学会，保留所有权利）
