Reliability and validity of the Japanese version of the Perth Emotion Regulation Competency Inventory (PERCI)

Abstract

Regulating emotions appropriately is vital to our lives. Most of the self-assessment scales that have been developed to measure emotion regulation ability focus only on negative emotions. The Perth Emotion Regulation Competency Inventory (PERCI), a 32-item instrument developed by Preece et al. (2018), provides a comprehensive measure of the ability to regulate positive and negative emotions. The purpose of this study was to create the Japanese version of the PERCI and examine its reliability and validity. Confirmatory factor analyses were conducted, and the concurrent validity and test-retest reliability of the Japanese version of the PERCI were checked; the results indicated that it was reliable and valid. Therefore, this scale can contribute to emotion regulation research in Japan.
