Childhood trauma and parental bonding among Japanese female patients with borderline personality disorder
The present study explored the relationship between borderline personality disorder (BPD) and childhood trauma and perceived parental behaviours among a sample of Japanese female outpatients. Participants were 45 female patients who were diagnosed with BPD and 45 female patients with a diagnosis of other nonorganic psychological disorders (aged 19 to 53). The participants completed surveys that assessed recollection of childhood abuse and neglect, perceived parental‐rearing behaviours, and symptoms of BPD. MANOVAs and logistic regression analyses were conducted in order to analyse the data. The results showed that the patients with BPD reported more severe forms of childhood traumas, including emotional, physical, and sexual abuse and emotional and physical neglect, than did the non‐BPD patients. This is consistent with previous findings in North America that have reported higher prevalence and greater severity of various childhood traumas in individuals with BPD compared with those with non‐BPD disorders or nonclinical samples. This study also found that the patients with BPD recalled both of their parents as more overprotective/controlling and less caring than did the non‐BPD patients. Last, logistic regression analyses found significant predictors of BPD diagnosis were reported emotional abuse and neglect as well as perceived paternal overprotection. Overall, these results indicate that whereas psychological risk factors in Japan are similar to those reported elsewhere, the same pathology can emerge from somewhat different causal pathways.
