​Work package 1 will develop and refine a community wealth building Theory of Change. A theory of change is a simple explanation of how and why an action (in this case actions related to community wealth building) is expected to lead a particular result (in this case, changes in health outcomes).   A theory of change shows the steps from what you do (actions) to what changes, as a result (outcomes). The theory of change for this community wealth building project will be informed by previous work on community wealth building, specifically, the Public Health Scotland, Health Impact Assessment. We will also hold three workshops in this first work package with stakeholders involved in community wealth building to discuss and set out the pathways by which community wealth building is expected to improve health and reduce health inequalities while identifying any potential unintended outcomes.
