Abstract
BACKGROUND: Literature data about emotion perception in patients with borderline personality disorders (BPD) revealed some discrepancies between some patients that are vigilant and accurate to detect their emotional environment and others that are impaired at identifying emotions of others. Even if some links between childhood adversity and facial affect recognition have been established, there is a need to understand the heterogeneous psychobiological mechanisms underlying this association. The aim is to distinguish in a BPD sample, the links between facial emotion recognition (FER) and adversity types (maltreatment and parental bonding), by evaluating two dimensions of disengaged and controlling environment. METHOD: The study includes BPD adolescents (n = 45) and healthy controls (HC, n = 44): two scores of disengaged environment (parental low care; emotional and physical neglect) and controlling environment (high level of parenting control; emotional, physical and sexual abuse) were established and correlated to FER, as well as to attachment dimensions. Multiple linear regression analyzes were conducted to evaluate the effect of disengaged and controlling dimensions, on FER scores of sensitivity and accuracy, including anxious and avoidant attachment as covariables. RESULTS: Analyzes revealed that a disengaged environment was positively correlated to sensitivity in BPD patients, and the correlation was negative in the HC group. Controlling environment was negatively associated to accuracy of emotion in BPD. Avoidant and anxious attachment did not influence these associations. CONCLUSIONS: These results suggest that distinct adverse experiences account for the heterogeneity observed in emotion regulation in BPD patients.
