This module will help your team examine the personal and environmental factors that contribute to the health issue you’re working on. We start with an overview of socio-ecological assessments, then, as you start the step-by-step process, we explore themes in population health research to help you find evidence to the role of the determinants of health and health disparities in the issue. This module also sets you on a search for research evidence to help you decide which determinants can be modified and which levels and sectors you should focus your intervention on.
