Emotion regulation is a fundamental process that involves monitoring, evaluating, and modifying emotional responses to achieve personal goals. Recently, a growing body of research has challenged the exclusive focus on individual emotion regulation strategies due to conceptual and empirical overlaps among them. This study explored the higher-order factor structure of emotion regulation strategies within the South Korean cultural context. Through a survey of 450 Korean adults and utilizing exploratory and confirmatory factor analyses, we examined the structure of emotion regulation strategies. Our results indicate that a four-factor model fit the data best. Regarding maladaptive emotion regulation strategies, our study identified two higher-order factors: disengagement and cognitive perseverance strategies. Notably, we also found two higher-order factors of adaptive strategies in the South Korean context: acceptance-based regulation and effortful cognitive regulation factors. Through the examination of the fitness of the structure of emotion regulation strategies from a Western sample to a South Korean sample, this study adds to the body of research on emotion regulation, highlighting the significance of targeting higher-order emotion regulation factors in cognitive behavioral therapy. •Factor analysis reveals 4 factors of emotion regulation in South Korean culture.•Four factors are Disengagement, Perseverance, Acceptance, Effortful control.•We suggest targeting higher-order emotion regulation factors in psychotherapy.
