Abstract

Introduction: No stroke-specific cognitive screen currently exists for community-dwelling chronic stroke survivors, with primary care and community settings relying on dementia tools which often do not consider specific post-stroke impairments. The Oxford Cognitive Screen (OCS) was developed for use in acute stroke, but its administration time is prohibitive for brief screening. Here, we aimed to develop, standardise and psychometrically validate the Mini-Oxford Cognitive Screen (Mini-OCS), a brief (<8 min) cognitive screen aimed for use in chronic stroke.

Method: Existing full OCS data for 464 English participants who were ⩾6 months post-stroke were analysed for the possibility of a short-form. Theoretical choices were made to adapt the short-form to be suitable for use in chronic stroke. The Mini-OCS was then completed by 164 neurologically healthy controls (M_age = 68.66; SD = 12.18, M_years of education 15.40; SD = 3.64, 61% female), and 89 chronic stroke survivors (M_age = 69.86; SD = 14.83, M_years education = 14.29; SD = 4.01, 44.94% female, M_days since stroke = 597.02; SD = 881.12, 78.57% ischaemic, Median NIHSS = 6.5 (IQR = 4-11)). In addition, the original OCS, the Montreal Cognitive Assessment, and an extended neuropsychological battery were administered. Psychometric properties of the Mini-OCS were evaluated via construct validity and retest reliability.

Findings: Normative data for the Mini-OCS is provided and known-group discrimination demonstrates increased sensitivity in the memory and executive function domains compared to the OCS. The Mini-OCS further met all appropriate benchmarks for evidence of retest reliability and construct validity.

Discussion and conclusion: The Mini-OCS is a short-form standardised cognitive screening tool with initial evidence of good psychometric properties for use in a chronic stroke population.

迷你牛津认知屏幕（Mini-OCS）：一种用于慢性中风的非常简短的认知屏幕。

目前没有针对社区居住的慢性中风幸存者的中风特异性认知筛查，初级保健和社区环境依赖于痴呆症工具，这些工具通常不考虑特定的中风后损伤。牛津认知筛查（OCS）是为急性中风而开发的，但它的给药时间对于短暂的筛查是令人望而却步的。在这里，我们的目标是开发，标准化和心理测量学验证Mini-Oxford认知屏幕（Mini-OCS），一种简短的(方法：分析464名卒中后大于或等于6个月的英国参与者的现有完整OCS数据，以分析短形式的可能性。从理论上进行了选择，使其适应于慢性中风的使用。随后，164名神经健康对照者（Mage = 68.66, SD = 12.18，受教育年数15.40;SD = 3.64，女性占61%）和89名慢性卒中幸存者（Mage = 69.86, SD = 14.83，受教育年数14.29;SD = 4.01，女性占44.94%，卒中后Mdays = 597.02, SD = 881.12，缺血性患者78.57%，NIHSS中位数= 6.5 (IQR = 4-11)）完成Mini-OCS。此外，还进行了原始的OCS，蒙特利尔认知评估和扩展的神经心理学电池。通过构念效度和重测信度对Mini-OCS的心理测量特性进行评价。研究结果：提供了Mini-OCS的规范数据，与OCS相比，已知组辨别在记忆和执行功能领域表现出更高的敏感性。Mini-OCS进一步满足了所有适当的重测信度和结构效度的证据基准。讨论和结论：Mini-OCS是一种简短的标准化认知筛查工具，具有良好的心理测量特性，可用于慢性卒中人群。

期刊介绍： Launched in 2016 the European Stroke Journal (ESJ) is the official journal of the European Stroke Organisation (ESO), a professional non-profit organization with over 1,400 individual members, and affiliations to numerous related national and international societies. ESJ covers clinical stroke research from all fields, including clinical trials, epidemiology, primary and secondary prevention, diagnosis, acute and post-acute management, guidelines, translation of experimental findings into clinical practice, rehabilitation, organisation of stroke care, and societal impact. It is open to authors from all relevant medical and health professions. Article types include review articles, original research, protocols, guidelines, editorials and letters to the Editor. Through ESJ, authors and researchers have gained a new platform for the rapid and professional publication of peer reviewed scientific material of the highest standards; publication in ESJ is highly competitive. The journal and its editorial team has developed excellent cooperation with sister organisations such as the World Stroke Organisation and the International Journal of Stroke, and the American Heart Organization/American Stroke Association and the journal Stroke. ESJ is fully peer-reviewed and is a member of the Committee on Publication Ethics (COPE). Issues are published 4 times a year (March, June, September and December) and articles are published OnlineFirst prior to issue publication.
