With joint interpersonal and affective impairments associated with personality disorders, understanding the intersection of these processes in these disorders is a critical emerging trajectory for research. An emerging line of research has been devoted to understanding interpersonal emotion regulation processes in personality disorders. This relatively nascent research area has recently gained traction internationally. This special section summarizes some of the recent innovations in this area of research. These investigations have harnessed a diverse range of methods, including dyadic approaches, intensive longitudinal assessments, and information processing perspectives. Moreover, this section suggests that interpersonal emotion regulation is relevant to personality disorders beyond borderline personality disorder. This summary of innovative approaches is timely and can propel future clinically relevant and impactful research in this area. We provide recommendations for important next steps in this area of research. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
