As part of a standard evaluation of neuropsychological sequelae, the Wechsler Memory Scale-Revised (WMS-R) was administered to 107 patients with a history of traumatic brain injury. Confirmatory factor analyses were conducted on the 12 subtests of the WMS-R to examine the fit of various hypothesized factor patterns, including patterns identified in previous exploratory factor analytic studies. Because part of the correlation between immediate and delayed recall trials of the same material is attributable to a common measurement procedure, this correlation due to measurement commonality was partialled out of the conceptual factor structure. The results suggested the presence of 3 distinct but highly correlated factors: attention/concentration, immediate memory, and delayed recall. Models that posited separate verbal and nonverbal memory processes failed to improve fit over more parsimonious models. Comparisons with previous factor analytic studies and implications for clinical assessment are discussed.
作为对神经心理学后遗症进行标准评估的一部分，对107名有创伤性脑损伤病史的患者施行了韦氏记忆量表修订版（WMS-R）测试。对WMS-R的12个分测验进行了验证性因素分析，以检验各种假设因素模式的拟合度，包括先前探索性因素分析研究中确定的模式。由于同一材料的即时回忆试验和延迟回忆试验之间的部分相关性归因于共同的测量程序，因此这种由测量共性导致的相关性从概念性因素结构中被分离出来。结果表明存在3个不同但高度相关的因素：注意力/专注力、即时记忆和延迟回忆。提出单独的言语和非言语记忆过程的模型，与更简约的模型相比，未能改善拟合度。文中讨论了与先前因素分析研究的比较以及对临床评估的意义。
