Mechanisms of change in external implementation support: A conceptual model and case examples to guide research and practice.

The proposed model is intended to support prospective EIS studies by conceptualizing discernable practice components with hypothesized relationships to proximal and distal practice outcomes. The model can be behaviorally operationalized to compliment and extend competency-based approaches to implementation support practitioner (ISP) training and coaching. Over time, the model should be refined based on new empirical findings and contributions from ISPs across the field.
