Development of a Japanese Version of the Creative Mindset Scale (CMS) Using Item Response Theory

Abstract

The purpose of this study was to develop the Japanese version of the Creative Mindset Scale (CMS-J) and examine its psychometric properties using classical test theory (CTT) and item response theory (IRT). Three surveys were conducted to examine the psychometric properties. Study 1 (n = 700) confirmed the conceptual structure of the CMS-J. Confirmatory factor analyses of the CMS-J suggested a two-factor structure, as in the original scale. The test–retest reliability was examined based on data from 143 participants who responded to the CMS-J questionnaire after a 7-week interval. Study 2 (n = 1,114) confirmed the convergent and discriminant validities, as well as the internal consistency, of the CMS-J. Finally, Study 3 (n = 1,300) confirmed the effective measurement of growth and fixed mindset of the CMS-J using IRT analyses. The present findings suggest that the CMS-J has a fundamental psychometric property.
