Summary
本文提出了一种开发脑卒中功能评估 (CAT-FAS) 计算机自适应测试系统的协议。CAT-FAS 可以同时评估四个功能 (两个运动功能 (上肢和下肢)、姿势控制和日常生活的基本活动), 具有足够的可靠性和行政效率。
Abstract
脑卒中功能评估 (CAT-FAS) 的计算机自适应测试系统可以同时评估四个功能 (上肢和下肢的运动功能、姿势控制和日常生活的基本活动), 并充分可靠性和行政效率。cat 是一种现代的测量方法, 旨在快速对考生的功能水平进行可靠的估计。cat 只管理几个项目, 其项目困难与考生的职能水平相匹配, 因此, cat 的管理项目可以提供足够的信息, 在短时间内可靠地估计考生的功能水平。CAT-FAS 是通过四个步骤开发的: (1) 确定物料库, (2) 确定停止规则, (3) 验证 CAT-FAS; (4) 建立在线管理平台。本研究结果表明, CAT-FAS 具有足够的管理效率 (平均项目数量 = 8.5) 和可靠性 (群级拉什可靠性: 0.88-0.88; 个人级拉什可靠性: ≥70% 的患者具有 rschh 可靠性评分≥0.90), 同时评估脑卒中患者的四种功能。此外, 由于 sat-fas 是一种基于计算机的测试, 因此 CAT-FAS 还有三个额外的优点: 自动计算分数、立即存储数据和轻松导出数据。CAT-FAS 的这些优势将有利于临床医生和研究人员的数据管理。
Introduction
上肢和下肢功能障碍 (ue 和 le)、姿势控制和日常生活基本活动 (badl) 是中风1、2、3 的主要后遗症。评估脑卒中患者的这四种功能对于临床医生评估患者的功能障碍程度、设定治疗目标和计划以及监测这些功能的纵向轨迹至关重要。
fugl-meyer 评估 (fm),4中风患者的体位评估量表 (pass),5和 barthel 指数 (bi) 6 具有良好的心理测量特性, 以评估 uele 运动功能, 姿势控制, 和 bardel,分别为脑卒中患者7,8,9。然而, 这三项措施总共有72个项目妨碍了在有时限的治疗会议上评估所有三项措施的可行性。需要一种更有效的测试方法。计算机自适应测试 (cat) 是一种现代测量方法。与传统的测量方法相比, cat 在更短的时间内对考生的功能水平进行了更可靠的估计。在传统的测量方法中, 每个考生都会收到相同的测试表 (或项目集), 其中许多项目对考生来说太难或太容易了。这些项目为估计考生的功能水平提供了有限的信息, 对考生来说是耗时的。相反, 在 cat 中, 每个考生都会得到一个量身定制的项目集, 其中所选项目的难度级别与考生的功能水平一致。由于这些项目是为特定考生量身定制的, cat 可以用更少的项目对考生的功能水平进行更可靠的估计, 从而减少得多。cat 开发的步骤见补充文件 1: 附录 1.
由于禁止酷刑委员会承诺进行可靠和有效的评估, 因此制定了 cat-fas, 以提高以前使用的三项措施 (fm、pass 和 bi)13的行政效率。本文介绍了 CAT-FAS 的发展和管理。该协议为研究人员开发其 cat 提供了信息, 并为 CAT-FAS 的潜在用户提供了管理这些信息的信息。我们还解决了 CAT-FAS 的长处和短处。

Discussion
这里给出的结果表明, 在最初的测试中, CAT-FAS 管理了大约10% 的项目 (在 CAT-FAS 中使用的平均项目数: 8.5 项与原始测试中使用的项目数:72 项)。这些结果表明, CAT-FAS 具有良好的行政效率。研究结果与此前的研究一致, 此前的研究报告称, cat 只管理了大约10个项目或更少的项目, 以评估中风患者的社会功能、平衡或日常生活活动 10、11、<sup class…
