Description
Summary:•Major depressive disorder may coexist with borderline personality disorder.•Comorbid borderline personality disorder involves worse clinical course and lower treatment response.•Assessment of comorbid borderline personality is necessary for depressive patients.•Child emotional abuse may contribute to develop borderline personality disorder.•Deficits in emotion regulation are significantly associated with borderline personality. Borderline personality disorder (BPD) show different course and treatment compared to major depressive disorder (MDD). Early life stress may increase BPD onset; however, resilience may play a protective role against the development of psychopathology. The goal of this study was to compare the early life stress, resilience, and the clinical characteristics of emotional dysregulation in patients with MDD with and without comorbid BPD. Thirty patients with both BPD and MDD, 25 patients with MDD alone, and 25 age- and sex- matched healthy controls, participated in this study. Analysis of variance was used to compare the early life stress, resilience, and emotional dysregulation among groups. Also, multivariate logistic regression models were used to identify the relationship of the early life stress and resilience domains with BPD comorbidity within MDD patients. The domains of emotional abuse and self-regulation ability were significantly associated with BPD comorbidity and BPD severity. In emotional dysregulation, difficulty scores of impulsivity, coping strategies, and emotion clarity domains were significantly increased in patients with both BPD and MDD compared to patients with MDD alone. The relatively small sample size may contribute to reduce statistical power of investigation. Emotional abuse experiences in early life, and deficits in self-regulation, are significantly associated with comorbid BPD in patients with MDD. A comprehensive evaluation including early life stress, resilience and emotion regulation ability may help to identify comorbid BPD in patients with MDD and develop treatment strategies.
