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

要旨

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.
