Pattern of social cognition deficits in individuals with borderline personality disorder

Background: Social cognition deficits have been implicated in the affect regulation and interpersonal difficulties seen in borderline personality disorder (BPD). The study examined patterns of social cognition abilities, using self-report and task-based measures, among individuals diagnosed with BPD. Methods: The sample included a clinical group of 20 patients diagnosed with BPD and 20 age and gender-matched control group participants from the community with no psychiatric diagnosis. The measures included the Mentalization Questionnaire, the Reading the Mind in the Eyes Test and the Social Cognition Rating Tool in Indian Setting. Results: Results indicated that the clinical group had lower self-reported mentalizing ability. Facial emotion recognition ability was significantly lower for the clinical group, particularly for photographs of the eye region with positive and neutral valences. The clinical group had significantly higher personalizing bias, and greater difficulties in social perception. The two groups did not differ on first and second order theory of mind, recognition of faux pas and externalizing bias. Conclusions: The results point to the links between social cognition deficits and interpersonal difficulties among persons with BPD. Implications include the need for pre-therapy assessment of the magnitude and patterns of social cognition difficulties in BPD, the development of culturally and ecologically valid assessments and the evaluation of interventions for social cognition vulnerabilities among individuals with BPD.
