Abstract

Abstract: Borderline personality disorder (BPD) is characterized by anger rumination and expression, and these features are associated with Behavioral Inhibition and Activation Systems (BIS/BAS). This longitudinal study investigates the role of effective and ineffective coping strategies in mediating the association between BIS/BAS and anger rumination/expression in patients with BPD. This longitudinal study was performed on outpatients with BPD referring to two clinical and research centers in China from June 2019 to June 2021. A total of 340 patients with BPD were included in this study. Participants were investigated with BIS/BAS and Brief COPE at baseline and with anger rumination/expression questionnaire at a one-year follow-up session. Our findings demonstrated a significant indirect effect of BAS-Reward and BAS-Drive through problem-based coping skills on anger expression one year later. Besides, we found a significant indirect effect of BIS through avoidant coping skills on anger rumination one year later. Nonetheless, we failed to show a significant mediatory role for emotion-based coping skills. Our findings might have valuable implications for future studies that investigate anger management strategies based on personality traits and coping skills of patients with BPD. Highlights: Borderline personality disorder is characterized by anger rumination/expression. An indirect effect of BAS via problem-based coping skills on anger expression An indirect effect of BIS through avoidant coping skills on anger rumination We failed to show a significant mediatory role for emotion-based coping skills.
