Testing and Exploring the Limits of Traditional Notions of Fidelity and Adaptation in Implementation of Preventive Interventions.

This commentary reflects on key challenges raised across the articles of this special issue, notably the tension between fidelity and adaptation, the importance of articulating core components and principles of evidence-based programs, the need for pragmatic measures, and the challenges associated with articulating and testing mechanisms of implementation strategies. These challenges are amplified in the context of prevention research where task shifting, or revising professional roles, is especially common. Synergies with work emerging from the Society for Implementation Research Collaboration are highlighted throughout.

Applying KT Network Complexity to a Highly-Partnered Knowledge Transfer Effort Comment on "Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation".

The re-conceptualization of knowledge translation (KT) in Kitson and colleagues' manuscript "Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation" is an advancement in how one can incorporate implementation into the KT process. Kitson notes that "the challenge is to explain how it might help in the healthcare policy, practice, and research communities." We propose that these concepts are well presented when considering highly-partnered research that includes all sectors.

Barriers, facilitators, and benefits of implementation of dialectical behavior therapy in routine care: results from a national program evaluation survey in the Veterans Health Administration.

National implementation of evidence-based psychotherapies (EBPs) in the Veterans Health Administration (VHA) provides important lessons on the barriers and facilitators to implementation in a large healthcare system. Little is known about barriers and facilitators to the implementation of a complex EBP for emotional and behavioral dysregulation-dialectical behavioral therapy (DBT). The purpose of this study was to understand VHA clinicians' experiences with barriers, facilitators, and benefits from implementing DBT into routine care.
