Abstract

Borderline personality disorder is one of the most prevalent disorders of axis II in psychiatry in which problems in interpersonal relationships is one of the most important problems of the patients. Linehan suggested that the patients problems are due to emotion dysregulations & emotion dysregulations are consequence of biological factors especially frontal lobe function & abnormal personality dimensions. Therefore, 130 patients with BPD completed TCI & PAI-BPF inventories & computerized emotion discrimination task. Also, the cortical activities of participants were recorded by EEG & analyzed by QEEG. Results indicated that absolute power of alpha band in frontal lobe & temperament character dimensions (novelty seeking, harm avoidance, reward dependency & cooperation) could predict emotional discrimination & interpersonal problems of BPD patients. Also, emotion discrimination could predict interpersonal problems. These results suggest that emotion discrimination ability could mediate relationships among alpha absolute power & temperament character dimensions with interpersonal problems f BPD patients.
