：在LIS领域，“批判思维”常作为信息素养教育的核心培养目标和信息行为等研究的解释或调节变量。在测度该变量时，研究者往往采用影响广泛的《加利福尼亚批判思维倾向量表》（简称CCTDI）或对应的中文量表（简称CTDI-CV）。然而备受困扰的是该版本存在未经结构效度检验、因子结构不稳定、题目数量过多等不足。文章旨在考察对现有量表进行简化的可行性，探索面向LIS研究与实践需要的简化版批判思维量表。依据383个有效样本的数据，文章开展了项目分析、因子分析、信度检验等研究过程，最终形成的量表由6个维度、28道题目构成；KMO为0.820，解释率为50.208%，α系数为0.80，各维度系数为0.45-0.78。与现有其他量表相比，文章在信度、因子结构和解释力等方面维持了水准，并进行了结构效度检验、实现了题量精简。

Critical thinking is widely used in the field of Library and Information Science, regarded as the core training objective of information literacy education and the explanatory or moderator variable of information behavior research. In measuring this variable, researchers often use the California Critical Thinking Disposition Inventory (CCTDI) and the corresponding Chinese version (CTDI-CV). However, there are many problems in this version, such as no structural validity test, unstable factor structure, and too many items (more than 70). The purpose of this study is to investigate the feasibility of simplifying the existing scale, and to explore a simplified critical thinking scale for LIS research and practice. Based on the data of 383 valid samples, this study carried out project analysis, factor analysis, reliability test and other research processes. The simplified scale consists of six dimensions and 28 items. The KMO is 0.820, and the explanation rate is 50.208%. The overall alpha is 0.90, and subscale alphas range between 0.45 and 0.78. Compared with other scales, the result of this study maintains the level of reliability, factor structure and explanatory power. The test of structure validity is carried out, and the number of questions is reduced.
