本研究采用13项创造力自评量表（SRCS）对员工的创造力进行评价。然而，目前尚不清楚修改后的SRCS是否在心理测量学上是合理的。本研究在三项研究中解决了这一差距（N = 1，033）。探索性因子分析（研究1）显示，由于因子负荷低，在删除项目9后，存在双因子解。研究二采用实证因素分析方法，对13个项目的概念性单因素模型（模型1）、12个项目的单因素模型（模型2）、12个项目的双因素模型（模型3）和1个一般因素和2个特殊因素的12个项目的双因素模型（模型4）进行了检验和比较。结果表明，模型4比所有竞争模型更具有上级优势。研究3进一步证实了双因素模型的信度和收敛效度，并发现部分度量不变性在中国和马来大学生。两者合计，修改后的（12项）SRCS是一个心理测量健全的工具，在马来西亚的背景下，自我评价的创造力。
The 13-item self-rated creativity scale (SRCS) initially developed for supervisory rating of employees' creativity was modified by some researchers and used as a self-report of creativity. However, it is not clear if the modified SRCS is psychometrically sound. The present study addressed this gap in three studies (N = 1,033). The exploratory factor analysis (Study 1) revealed a two-factor solution after removing Item 9 due to low factor loading. Confirmatory factor analysis was then used in Study 2 to examine and compare the conceptual one-factor model with 13 items (Model 1), one-factor model with 12 items (Model 2), two-factor model with 12 items (Model 3), and the 12-item bifactor model with one general factor and two specific factors (Model 4). The results indicated that Model 4 is more superior to all the competing models. Study 3 further confirmed that the bifactor model, showed support to the reliability and convergent validity, and found partial metric invariance across Chinese and Malay undergraduates. Taken together, the modified (12-item) SRCS is a psychometrically sound tool for self-rated creativity in the Malaysian context.
