Development of the Japanese Version of the Short Scale of Creative Self†

Abstract

This study aimed to translate the Short Scale of Creative Self (SSCS) into Japanese and examine its psychometric properties. In total, 1,436 participants (Study 1: N = 957, Study 2: N = 479) completed the questionnaires. In Study 1, confirmatory factor analyses for Japanese versions of the scales resulted in bi-factor structures comprising one general factor and two subfactors; namely, creative self-efficacy (CSE) and creative personal identity (CPI). However, the Japanese version of the SSCS (SSCS-J) was essentially unidimensional, and scoring based on CSE and CPI lacked support. Therefore, it was necessary to calculate the total SSCS-J item scores to measure the creative self. Study 2 provided evidence for the concurrent, convergent, and discriminant validity of the scale. The current study also found that the SSCS-J had adequate test–retest reliability. The present findings suggest that the SSCS-J has sufficient reliability and validity.
