Across five levels: The evidence of impact model:

This article describes The Evidence of Impact Model that was recently developed to support the analysis of short- to medium-term impact arising from Participatory Action Research and Developmental Evaluation approaches that were used within the Evidence for Change initiative. Evidence for Change was a team capacity building initiative that supported rapid, bottom-up, evidence informed change in health and social care environments. To explain the need for The Evidence of Impact Model and outline how it was developed, a variety of similar models are explored and the challenges of capturing impact arising from Evidence for Change are discussed. The resulting new model based on the existing concept of micro, meso and macro levels of impact is outlined in detail with supporting qualitative evidence. The authors conclude that The Evidence of Impact Model provides an effective lens for exploring impact at a variety of levels within an emerging and complex environment.
