Borderline personality disorder level predicts change in depressiveness after short‐term group psychotherapy: A study in a daily psychiatric clinic

The project examined the comorbidity between depression symptoms and the level of borderline personality organisation among patients admitted for group psychotherapy (Study 1). It also aimed to analyse how the level of borderline personality organisation relates to the reduction in depression symptoms after short‐term psychotherapy (Study 2). The study was conducted in a day clinic where patients were receiving psychotherapy for emotional problems affecting their functioning (N = 57). The study used the Borderline Personality Inventory (BPI) and the Patient Health Questionnaire. The analysis showed that BPI was positively related to depression symptoms. The higher borderline personality organisation patients presented when entering group psychotherapy, the greater was the decrease in depression symptoms after 3 months of psychotherapy. We discuss the results in relation to the notion that the presence of depression could be a positive prognostic indicator for patients with borderline personality.
