Adapting dialectical behavior therapy in Mandarin-speaking Chinese patients with borderline personality disorder: An open pilot trial in Taiwan

Introduction Dialectical behavior therapy (DBT) is the most commonly used treatment for patients suffering from borderline personality disorder (BPD). However, data on its applications in Asian countries remain lacking. This pilot study aims to evaluate the feasibility and effectiveness of applying Mandarin-translated DBT among suicidal Chinese patients with BPD in Taiwan. Methods An open-label trial design was implemented for the 1-year standard DBT model. Patients from a psychiatric outpatient department in a general hospital in Taiwan with a history of >= 2 episodes of suicidal behavior within the previous year and who scored >40 on the Borderline Symptom List were invited to participate in this trial. Outcomes of suicidal behaviors, severity of BPD and depression symptoms, suicidal ideation, hopelessness, and quality of life were assessed at the beginning of the treatment and every 3 months until 12 months. Results Eighteen patients participated, three of whom (16.7%) dropped out. Significant improvements were found in the frequency and severity of suicidal behaviors and ideations, depressive symptoms, and BPD symptoms beginning as early as the third month after initiating DBT. Discussion This pilot study found that DBT may be an effective and feasible intervention for Mandarin-speaking individuals with a recent history of suicidal behaviors with BPD. Future randomized controlled trials with comparison groups are needed to further determine the efficacy of DBT on this population.
