Relationship quality and stability in couples when one partner suffers from borderline personality disorder

Abstract

The main goal of the present study was to examine and compare the psychosocial functioning of 35 couples including a woman diagnosed with borderline personality disorder (BPD) to that of a nonclinical control sample of 35 couples. The BPD status of women from the clinical group and the prevalence of personality disorder in their partner were ascertained through the SCID-II. Participants completed self-report measures of couple functioning. A majority of couples in which the woman suffered from BPD (68.7%) evidenced frequent episodes of breakups and reconciliations and, over an 18-month period, nearly 30% of these couples dissolved their relationship. Nearly half of the men involved in a romantic relationship with a woman suffering from BPD met criteria for one personality disorder or more. As compared with nonclinical couples, clinical couples showed lower marital satisfaction, higher attachment insecurity, more demand/withdraw communication problems, and higher levels of violence.
