This study aims to measure the psychometric properties of the Das-Naglieri Cognitive Assessment System (D-N CAS) and to determine its clinical utility in a Chinese context. Confirmatory factor analysis (CFA) was conducted to examine the construct validity of the Chinese version of the D-N CAS among a group of 567, normally developed children. Test-retest reliability was examined in a random subsample of 30 children at a five-week interval. The clinical discrimination of the D-N CAS was also examined by comparing children with and without ADHD (18 children in each group) and by comparing children with and without Chinese reading disabilities (18 children in each group). The current Chinese sample demonstrated a four-factor solution for cognitive performance among children with normal development: Planning, Attention, Simultaneous processing and Successive processing (χ2(48)=91.90, p=.000; χ2/df=1.92, RMSEA=.050, GFI=.966, CFI=.954). Moreover, all subtests of the battery demonstrated acceptable test-retest reliability (r=.72-.90, p<.01) at a five-week interval among the subjects of the small subsample. Children with ADHD performed significantly worse than normal children on the Attention factor (p<.001) and the Planning factor (p<.05) of the D-N CAS, and children with Chinese reading disabilities performed significantly worse than normal children on the Simultaneous processing factor (p<.01), the Successive processing factor (p<.001) and the Planning factor (p<.05) of the D-N CAS. These findings suggested that the current four-factor structure of the D-N CAS was similar to the original factor structure of the test. The latent factor of the D-N CAS was fairly stable across the cultures. Moreover, the D-N CAS can distinguish between children with ADHD or Chinese reading disabilities and normally developed children.
本研究旨在测量 Das-Naglieri 认知评估系统（D-N CAS）的心理测量特性，并确定其在中国背景下的临床应用价值。对一组 567 名正常发育儿童进行验证性因素分析（CFA），以检验中文版 D-N CAS 的结构效度。在五周的间隔时间内，对 30 名随机子样本进行测试-重测信度检验。通过比较患有和不患有注意缺陷多动障碍（ADHD）的儿童（每组 18 名儿童）以及比较患有和不患有中文阅读障碍的儿童（每组 18 名儿童），也检验了 D-N CAS 的临床区分能力。当前的中国样本在正常发育儿童的认知表现中表现出四因素解决方案：计划、注意力、同时处理和连续处理（χ2(48)=91.90，p=.000；χ2/df=1.92，RMSEA=.050，GFI=.966，CFI=.954）。此外，在小样本的五周间隔时间内，电池的所有测验均表现出可接受的测试-重测信度（r=.72-.90，p<.01）。患有 ADHD 的儿童在 D-N CAS 的注意力（p<.001）和计划（p<.05）因子上的表现明显差于正常儿童，而患有中文阅读障碍的儿童在 D-N CAS 的同时处理（p<.01）、连续处理（p<.001）和计划（p<.05）因子上的表现明显差于正常儿童。这些发现表明，当前 D-N CAS 的四因素结构与测试的原始因素结构相似。D-N CAS 的潜在因素在文化之间相当稳定。此外，D-N CAS 可以区分患有 ADHD 或中文阅读障碍的儿童与正常发育的儿童。
