Affect regulation in women with borderline personality disorder traits.

Affect dysregulation is considered a defining feature of borderline personality disorder (BPD). In spite of this, there is a dearth of empirical research that examines affect regulation among persons with BPD. The present study examined the relationship between specific dimensions of affect regulation and borderline traits in a sample of 39 patients. Participants were administered the Personality Diagnostic Questionnaire-Revised to assess the degree of borderline traits and the Affect Intensity Measure and Affect Control Scale to assess dimensions of affect regulation, selected based on the biosocial theory of BPD. Results from hierarchical regression analyses indicated that level of affect intensity and affect control were significantly associated with number of BPD traits, even after controlling for level of depression. Findings for affect control remained significant even after controlling for affect intensity. These results, consistent with biosocial theory of BPD, suggest that persons with BPD experience emotions more intensely and have greater difficulty in controlling their affective responses.
