Abstract

Patients with borderline personality disorder (BPD) show interpersonal deficits, and altered emotional and oxytocin (OT) responses to social exclusion (Cyberball). In order to extend previous findings, this study applies a novel Cyberball variant. Nineteen BPD patients and 56 healthy controls (HC) played Cyberball for 2 minutes of inclusion, 5 minutes of partial exclusion by one of two co-players, and 2 minutes total exclusion by both. Plasma OT levels at baseline and after 7, 9, 15, and 40 minutes were measured with radioimmunoassay. BPD patients showed a greater aversive reaction and a trend for greater OT reduction after social exclusion than HC. BPD patients also tended to play less frequently with the excluder. Though limited by our sample size, we partially replicate previous findings. Our preliminary behavioral data support the notion of an altered OT regulation and reduced capacity for social cooperation in BPD.
