    Abstract: In recent years, researchers conceptualized BPD as a biological specially brain disorder. Crowell&#146;s revised biosocial model of BPD has stated that interaction of biological vulnerabilities specially frontolimbic dysfunctions with personality and temperamental factors play an important role in behavioral, cognitive and emotional symptoms of BPD. In order to study of relationships between absolute power of alpha in frontal with temperament and character for predicting of self injury behavior of BPD, 50 males with BPD and history of non suicidal self injuring behavior completed Temperament-Character Inventory-125 (TCI-125). EEG recorded with a 32 channels DC amplifier and acquisition software. Data analyzed by Multivariate Regression Method. Results indicated that there are significant correlations among frontal alpha power (r = -0.85, p = 0.001), novelty seeking (r = 0.45, p = 0.01), harm avoidance (r = -0.66, p = 0.001), cooperativeness (r = -0.38, p = 0.01) and self transcendence (r = 0.36, p = 0.01) with self injuring. Regression analysis showed that frontal alpha power, novelty seeking, harm avoidance and persistence predicted self injuring behavior (R = 0.89, R<SUP>2</SUP> = 0.79). The present study provides support for the validity of Crowell&#146;s Model of BPD as predictors of self injuring through frontal function and personality factors especially, frontal dysfunction and temperamental factors appear to have a significant influence on self injuring in BPD.
