Abstract

Emotion regulation ability is an important variable closely related to psychological problems. Various measurement tools have been developed. However, existing scales have limitations in terms of content validity or inclusiveness. The Perth Emotion Regulation Competency Inventory [PERCI] was developed to compensate for these limitations. It is a powerful tool for comprehensively evaluating positive and negative emotion regulation abilities. In this study, reliability and validity of the scale were tested on 809 adults aged 19 years or older in Korea using DERS-16, DERS-positive, ERQ-S, PAQ-S, ECRR-K 14, DASS-12, BFI-15, ASI-R, and the Korean version of PERCI (K-PERCI). The internal consistency was strong. The convergent validity and discriminant validity were also strong. The confirmatory factor analysis revealed that the eight-factor model without the higher-order structure applied was the most suitable one. Measurement invariance was confirmed through multi-group analysis. Multiple regression analysis showed that sub-factors of the K-PERCI significantly predicted levels of depression, anxiety, and stress. This suggests that the K-PERCI is a tool that can properly evaluate the ability to control emotions.
