Background and objectives Borderline personality disorder (BPD) is conceptualized as a disorder of heightened emotional reactivity and difficulties with emotion regulation. However, findings regarding emotional reactivity in BPD are mixed and there are limited studies examining emotion regulation capabilities in this population. Methods Twenty-five individuals with BPD and 30 healthy controls (HCs) engaged in a baseline assessment followed by the presentation of neutral and BPD-relevant negative images. Participants were instructed to react as they naturally would to the image, or to use a mindfulness-based or distraction-based strategy to feel less negative. Self-reported and physiological (i.e., heart rate, electrodermal activity, and respiratory sinus arrhythmia) measures were collected. Results Compared with the HCs, the BPD group exhibited elevated heart rate and reduced respiratory sinus arrhythmia at baseline. However, there were no differences in emotional reactivity in self-report or physiological indices between the two groups. In addition, the BPD group did not exhibit deficits in the ability to implement either emotion regulation strategy, with the exception that the BPD group reported less positive emotions while distracting compared with the HCs. Limitations This study is limited by a small sample size and the inclusion of a medicated BPD sample. Conclusions Emotion dysregulation in BPD might be better accounted for by abnormal baseline emotional functioning rather than heightened emotional reactivity or deficits in emotion regulation. Treatments for BPD might be enhanced by directly targeting resting state emotional functioning rather than emotional reactions or regulatory attempts.
Borderline personality disorder (BPD) is a disorder of affective instability, conflict in interpersonal relationships, and self-destructive behavior (Linehan, 1993). Prevalence estimates of BPD are as high as 6% (Grant et al., 2008) and approximately 23% of outpatients meet diagnostic criteria for the disorder (Korzekwa, Dell, Links, Thabane, & Webb, 2008). Prominent theories of BPD posit that emotion dysregulation is either the core feature of the disorder (Linehan, 1993) or a key facet of the disorder (Fonagy and Bateman, 2008 and Selby et al., 2009). Emotion dysregulation is broadly comprised of the coupling of abnormalities in emotional responding and difficulties regulating emotional responses (Linehan, 1993).
