The Scales of Cognitive and Communicative Ability for Neurorehabilitation (SCCAN; L. Milman & A. Holland, 2007) was developed in the hospital setting to address changes in assessment practice. The SCCAN was designed to provide an overview of impairment and activity limitations across 8 cognitive scales (Speech Comprehension, Oral Expression, Reading, Writing, Orientation, Attention, Memory, and Problem Solving). The scales were developed using item response theory so that tailored testing could be implemented to reduce test administration time. This research investigated the validity and reliability of the SCCAN.
A battery of neuropsychological tests was administered to 40 neurologically healthy control participants and 51 participants diagnosed with left-hemisphere pathology, right-hemisphere pathology, or probable Alzheimer's disease. Analyses were performed to assess test sensitivity and specificity, construct validity, administration time, and reliability.
The test accurately classified 95% of the control participants and 98% of the participants diagnosed with neurological disorders. Results indicate that the test also differentiated the performance profiles of the 3 clinical populations. In addition, test scores correlated significantly with external measures of the same cognitive areas. Mean administration time was 34 min. Test-retest stability (r = .96, p < .001) and internal consistency (r = .99, p < .001) coefficients were both significant, indicating that tailored testing procedures generated reliable test scores.
神经康复认知与沟通能力量表（SCCAN；L. 米尔曼和A. 霍兰德，2007年）是在医院环境中开发的，以应对评估实践中的变化。SCCAN旨在概述8个认知量表（言语理解、口语表达、阅读、写作、定向、注意力、记忆和问题解决）中的损伤和活动受限情况。这些量表是使用项目反应理论开发的，以便能够实施量身定制的测试，从而减少测试管理时间。本研究调查了SCCAN的有效性和可靠性。
对40名神经功能健康的对照参与者以及51名被诊断患有左半球病变、右半球病变或疑似阿尔茨海默病的参与者进行了一系列神经心理学测试。进行分析以评估测试的敏感性和特异性、结构效度、管理时间和可靠性。
该测试准确地将95%的对照参与者和98%被诊断患有神经疾病的参与者进行了分类。结果表明，该测试还区分了3个临床群体的表现特征。此外，测试分数与相同认知领域的外部测量结果显著相关。平均管理时间为34分钟。重测稳定性（r = 0.96，p < 0.001）和内部一致性（r = 0.99，p < 0.001）系数均显著，表明量身定制的测试程序产生了可靠的测试分数。
