PURPOSE OF REVIEW: This manuscript aims to take stock of emotion dysregulation and personality disorder (PD) research, review key findings, and highlight future directions. RECENT FINDINGS: Most emotion dysregulation research in PDs has focused on borderline personality disorder (BPD). BPD is characterized by high baseline negative emotion and the use of maladaptive emotion regulation strategies, but several other emotion dysregulation components may not be pervasively evident in the disorder. Trends in the BPD field that add nuance to the study of emotion dysregulation suggest that BPD may involve problems in the flexible, contextually based selection/implementation of emotion regulation strategies, as well as the development of appropriate emotion regulatory goals. Furthermore, relational stressors may elicit and maintain emotion dysregulation in BPD. Less research has examined emotion dysregulation in other PDs, but several PDs may involve deficits in emotional processes (e.g., lower behavioral inhibition and resistance of emotion-related impulses), particularly in interpersonal contexts. Emotion dysregulation is a nuanced and contextual problem which, for some PDs, may be particularly nested within interpersonal contexts. The BPD field and the increasing nuance of the study of emotion dysregulation within it points to key future research directions for the broader PD field.
