The California Verbal Learning Test (CVLT; Delis, Kramer, Kaplan, & Ober, 1987) data of 150 patients with traumatic brain injury (TBI) were evaluated to determine the latent underlying constructs as well as the possibility of performance subtypes with criterion validity. Confirmatory factor analysis of eight competing latent variable models suggested that a four-factor model (composed of Attention Span, Learning Efficiency, Delayed Recall, and Inaccurate Recall) fit the data relatively well. Two-stage cluster analysis of marker variables of each of these four factors suggested the presence of four reliable subtypes. Level of performance differences between these clusters were related to injury severity parameters. It is concluded that the CVLT is a sensitive and mulitfactorial measure of learning and memory after TBI. Specific recommendations for interpretation of clinically obtained CVLT profiles are provided.
对150名创伤性脑损伤（TBI）患者的加利福尼亚言语学习测验（CVLT；德利、克莱默、卡普兰和奥伯，1987年）数据进行了评估，以确定潜在的潜在结构以及具有效标效度的表现亚型的可能性。对八个相互竞争的潜在变量模型进行验证性因素分析表明，一个四因素模型（由注意力广度、学习效率、延迟回忆和错误回忆组成）与数据拟合得相对较好。对这四个因素各自的标记变量进行两阶段聚类分析表明存在四种可靠的亚型。这些聚类之间的表现差异水平与损伤严重程度参数相关。结论是，CVLT是TBI后学习和记忆的一种敏感且多因素的测量方法。提供了对临床获得的CVLT剖面图进行解释的具体建议。
