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.
