Prior research has not identified which of the available treatments for borderline personality disorder (BPD) will have the best outcomes for long-term symptom relief. This study compares two treatments, dialectical behaviour therapy (DBT) and general psychiatric management (GPM), in a randomized trial. Patient baseline variables were used to measure individual treatment response.
A moderator identification process was used to predict optimal treatment (either DBT or GPM) for patients. Characteristics examined in the model included BPD impulsivity symptoms, dependent personality traits, childhood emotional abuse, and social adjustment. Patients that received treatment plans predicted by the model showed significantly better long-term outcomes.
The study concludes that examining patient characteristics is beneficial in delivering more successful treatment for borderline personality disorder. It is suggested that combining data from multiple moderator identification processes may increase this effect. However, further research in personalized treatment for BPD is necessary.
