- Description
- Objectives: Borderline personality disorder is a complex mental disorder that is associated with a high degree of suffering for the individual. Dialectical behaviour therapy has been studied in the largest number of controlled trials for treatment of individuals with borderline personality disorder. The conversational model is a psychodynamic treatment also developed specifically for treatment of borderline personality disorder. We report on the outcomes of a randomised trial comparing dialectical behaviour therapy and conversational model for treatment of borderline personality disorder in a routine clinical setting. Method: Participants had a diagnosis of borderline personality disorder and a minimum of three suicidal and/or non-suicidal self-injurious episodes in the previous 12 months. Consenting individuals were randomised to either dialectical behaviour therapy or conversational model and contracted for 14 months of treatment (n = 162 commenced therapy). Dialectical behaviour therapy involved participants attending weekly individual therapy, weekly group skills training and having access to after-hours phone coaching. Conversational model involved twice weekly individual therapy. Assessments occurred at baseline, mid-treatment (7 months) and post-treatment (14 months). Assessments were conducted by a research assistant blind to treatment condition. Primary outcomes were change in suicidal and non-suicidal self-injurious episodes and severity of depression. We hypothesised that dialectical behaviour therapy would be more effective in reducing suicidal and non-suicidal self-injurious behaviour and that conversational model would be more effective in reducing depression. Results: Both treatments showed significant improvement over time across the 14 months duration of therapy in suicidal and non-suicidal self-injury and depression scores. There were no significant differences between treatment models in reduction of suicidal and non-suicidal self-injury. However, dialectical behaviour therapy was associated with significantly greater reductions in depression scores compared to conversational model. Conclusion: This research adds to the accumulating body of knowledge of psychotherapeutic treatment of borderline personality disorder and supports the use of both dialectical behaviour therapy and conversational model as effective treatments in routine clinical settings, with some additional benefits for dialectical behaviour therapy for persons with co-morbid depression.
