摘要:Implementation strategies are necessary to ensure that evidence-based practices are successfully incorporated into routine clinical practice. Such strategies, however, are frequently modified to fit local populations, settings, and contexts. While such modifications can be crucial to implementation success, the literature on documenting and evaluating them is virtually nonexistent. In this paper, we therefore describe the development of a new framework for documenting modifications to implementation strategies. We employed a multifaceted approach to developing the Framework for Reporting Adaptations and Modifications to Evidence-based Implementation Strategies (FRAME-IS), incorporating multiple stakeholder perspectives. Development steps included presentations of initial versions of the FRAME-IS to solicit structured feedback from individual implementation scientists (“think-aloud” exercises) and larger, international groups of researchers. The FRAME-IS includes core and supplementary modules to document modifications to implementation strategies: what is modified, the nature of the modification (including the relationship to core elements or functions), the primary goal and rationale for the modification, timing of the modification, participants in the modification decision-making process, and how widespread the modification is. We provide an example of application of the FRAME-IS to an implementation project and provide guidance on how it may be used in future work. Increasing attention is being given to modifications to evidence-based practices, but little work has investigated modifications to the implementation strategies used to implement such practices. To fill this gap, the FRAME-IS is meant to be a flexible, practical tool for documenting modifications to implementation strategies. Its use may help illuminate the pivotal processes and mechanisms by which implementation strategies exert their effects.
