About

Standard Dialectical Behavioral Therapy (DBT)is an effective treatment for Borderline Personality Disorder (BPD), particularly for patients with significant behavioral and affective dysregulation, including suicidality. However, DBT in its original format is delivered in 12 months, and even though currently there are shorter versions of the treatment being developed and tested, in the context of public mental health care in Chile a shorter, intensive and lighter version of the treatment is likely needed to help patients seeking help for BPD symptoms. This study will test whether a 3 month, intensive and simplified version of DBT is at least equivalent to standard six months DBT with all its components (skills training, individual therapy, coaching calls, and treatment-team consulting). 120 patients diagnosed with BPD we'll be randomly assigned to receive either the short, intensive 3-month intervention or the longer standard 6-month DBT intervention. Baseline measures will be taken pre-treatment, upon treatment completion, and at a 4-month follow-up. Session-to-session change in BPD symptoms will also be measured throughout the treatments. Primary outcomes for the study are BPD symptoms, frequency, and intensity of suicidal activity. Secondary outcome measures include depression scores, quality of life, and ER visits, and days in inpatient care.
