In this study, we created J-DERS, a Japanese version of the Difficulties in Emotion Regulation Scale (DERS; originally developed by Gratz and Roemer (2004)) in order to examine factor structure, reliability, and validity. The subjects included 451 undergraduate and graduate students. We conducted a survey and implemented a confirmatory factor analysis (CFA) that assumed a six-factor model of the DERS. Since initial results showed that the overall suitability was low, we implemented a CFA that assumed a four-factor model based on the four-domain theory of emotional ability presented by Gratz and Roemer (2004). As a result, the suitability proved to be higher than that obtained using the six-factor model. Concurrent validity was also confirmed through Japanese version of the negative mood regulation (J-NMR), feelings experience scale (FES), effortful control (EC), and the Japanese version of action control scale 90 (ACS-90). Moreover, internal consistency regarding each subscale of the J-DERS was confirmed.
