Multisite Implementation and Evaluation of 12-Month Standard Dialectical Behavior Therapy in a Public Community Setting.

Dialectical behavior therapy (DBT) is an effective intervention for treating adults with emotional and behavioral dysregulation. The National DBT Project, Ireland was established in 2013 to coordinate the implementation of DBT across public community mental health settings at a national level. This study describes the implementation and evaluation of DBT across multiple independent sites in adult mental health services (AMHS). The Consolidated Framework for Implementation Research was used to guide this national implementation where barriers and facilitators to DBT implementation were considered. Nine AMHS teams completed DBT training and delivered the standard 12-month program. One hundred and ninety-six adults with borderline personality disorder participated in the program, and outcome measures were recorded at four time points. Significant reductions on outcome measures, including frequency of self-harm and suicidal ideation, were observed. This study highlights that DBT can be successfully implemented in community mental health settings as part of a coordinated implementation.
