What must you know and do to get good outcomes with DBT?

Because little research has been conducted on which therapist-client interactions lead to intermediate and end-point improvements in Dialectical Behavior Therapy (DBT), we have a small evidence-base from which to specify what therapists must know and do in order to obtain good outcomes using DBT. As with other evidence-based practices, dissemination of DBT has defaulted to assumptions and methods from the "psychotherapy technology model," which emphasizes transfer of the validated treatment package from the research clinic to routine settings with high fidelity (Morgenstern & McKay, 2007). However, serious limitations of the psychotherapy technology model require pursuit of alternative complementary models to guide dissemination. One complementary approach is to use well-designed practice-based training research. In this approach, therapists learn modular competencies linked to a highly structured yet flexible clinical decision-making framework. Modular training of therapist competencies emphasizes the continuity of the component therapist strategies across evidence-based protocols rather than emphasizing the packages or manuals as separate and distinct. Key hypotheses about the change processes responsible for client change and the associated treatment strategies used to influence these change processes should be specified and measured at the level of client, therapist, and service delivery setting. Adopting this approach may offer advantages that apply to the dissemination and implementation of DBT and other evidence-based practices (EBPs).
