문항반응이론을 적용한 KCYPS 창의적 성격 문항의 타당화 연구

Abstract

This study aimed to examine whether the creative personality items of KCYPS 2018, adapted from Gough & Heilbrun’s (1983) Creative Personality Scale (CPS) reliably and validly measure the creative personality of middle school students. Applying item response theory to the creative personality items, it was found that five items, namely ‘snobbish, unconventional, individualistic, informal, reflective,’ demonstrated very high difficulty, while six items such as ‘unconventional, humorous, individualistic, informal, interests wide, reflective’ showed very low item discrimination. In addition, the analysis of DIF(Differential item function) of gender revealed that the item ‘sexy’ was more favorable for female students, while four items ‘capable, clever, insightful, inventive’ were more advantageous for male students. This indicated that, even with the same level of creative personality, it can be measured differently depending on gender. This study holds significance in rigorously validating the KCYPS 2018 creative personality items through item response theory. We finally highlighted the need for comprehensive development of creative personality scales considering factors such as age, sub-components of creativity, and response patterns.
