Objectives: The goal of this study was to assess the effectiveness of dialectical behavioral therapy (DBT) in treating post-traumatic stress disorder (PTSD) symptoms in patients with borderline personality disorder (BPD) compared to other interventions.
Background: PTSD and BPD are often comorbid, and effective treatment options are limited. DBT has shown promise in treating BPD, but its efficacy in treating PTSD symptoms in this population is unclear. This research aimed to deal with this gap in the literature.
Methods: The PRISMA guidelines were followed in conducting this systematic review. For this systematic review, papers published in Cochrane, Science Direct, PubMed, Google Scholar, and gray literature were considered without any exclusions based on country, setting, and date of publication. However, these studies were restricted to English and clinical trials involving human participants. Randomized controlled trials comparing DBT to other interventions in patients with PTSD and BPD were included.
Results: Four trials were included in this review. The findings showed a significant improvement in PTSD and BPD symptoms in those who received DBT intervention compared to those who received other interventions. However, one study showed that the DBT prolonged exposure protocol yielded better results than the regular DBT protocol. Notably, one study showed that NET was slightly more effective than DBT therapy after 12 months.
Conclusion: This study provides evidence that DBT can be used to treat PTSD symptoms in individuals with BPD. It suggests that the use of a prolonged exposure protocol may lead to better outcomes than the standard DBT approach. Practitioners should consider these findings when deciding on options for treating patients with both PTSD and BPD diagnosis. Further research is needed to determine if other interventions beyond DBT, are effective in this population over an extended period.
