Sustainment Rates and Factors for Multidimensional Family Therapy in Europe and North America

Abstract

This retrospective non-experimental study examined the short-term (2-year) and longer-term (5-year and 8-year) sustainment of 137 programs in Europe and North America implementing a single evidence-based practice (EBP), Multidimensional Family Therapy (MDFT). MDFT implementation and sustainment is based on the Stages of Implementation (SIC) model outlined by Saldana and colleagues. The study had two primary objectives: (1) to examine short-term and longer-term sustainment rates of MDFT in Europe and North America, and (2) to explore potential factors that may be associated with sustainment of MDFT in particular, and the potential implications for behavioral health EBPs more generally. Results show that 90% of MDFT programs were sustained for at least 2 years, 87% of the programs sustained for at least 5 years, and 70% for at least 8 years. These findings compare favorably with the previous research on implementing and sustaining evidence-based practices. The findings support the growing consensus that not only start-up funding but also ongoing financing either through governments or third-party payors may be essential for longer-term sustainability of EBPs in both Europe and North America. This study also highlights the potential value of multi-site program networks. Future research directions are suggested, such as examination of the potential importance of the quality and nature of the EBP itself, adaptability to different organizations and clients, and providing high-quality structured and empowering training and quality assurance to sustain evidence-based behavioral health interventions. These programmatic and clinician-level factors are critical areas for further investigation into the sustainment of EBPs.
