Summary

Many individuals living with borderline personality disorder (BPD) have experienced childhood trauma, such as abuse or neglect. A significant number of them also meet the criteria for post-traumatic stress disorder (PTSD). However, standard psychotherapies often do not address both conditions at the same time, which can affect treatment outcomes.

A research team in Germany developed and validated a 45-week individual psychotherapy that has shown promising results for individuals coping with both BPD and PTSD. It has already been adapted and offered in English-speaking settings such as Toronto and Boston.

This study aims to adapt this therapy into French in Quebec. Over 24 months, we will conduct a mixed-methods observational study to evaluate changes in symptoms (BPD, PTSD, and other comorbidities) and in daily functioning.

Dialectical Behaviour Therapy for Post-Traumatic Stress Disorder (DBT-PTSD)

DBT-PTSD is 45-week individual psychotherapy (DBT-PTSD) designed to treat adults presenting with both borderline personality disorder (BPD) and complex post-traumatic stress disorder (C-PTSD). The intervention integrates dialectical behavior therapy (DBT) skills, trauma-focused exposure-based interventions, and strategies from compassion-focused therapy and acceptance and commitment therapy. All participants will receive the full sequence of the therapy in outpatient settings, following the structured treatment protocol.
