Borderline personality disorder (BPD) is characterized by persistent emotion dysregulation (ED), and ED is one of the core features of BPD. In recent years, research aimed to identify distinct patterns of ED characteristic of patients with BPD. These efforts comprised translational approaches, including psychophysiological measures. Autonomic nervous system (ANS) dysfunction, indexed by reduced resting-state heart rate variability (HRV), is suggested to be a psychophysiological marker of ED. Reduced HRV is seen in patients with a variety of psychiatric disorders, including adolescents with depression and BPD. No previous study, to the best of our knowledge, addressed the association between ANS function and different measures of ED in adolescents with BPD. Here, we used a multimodal assessment of ED (self-reports, interviews, ambulatory assessment) in a sample of 43 adolescent patients (95.4% female, Mage = 15.5 years), fulfilling at least 3 BPD criteria. Replicating earlier findings, greater BPD symptom severity was significantly related to reduced resting-state HRV and increased heart rate. However, other measures of ED and mean affect were unrelated to ANS function. Findings suggest that ANS dysfunction maps to symptom severity in general rather than specific symptomatology (such as ED) in adolescents with BPD. Implications for the use of ANS measures in clinical practice and directions for future research are discussed.
