Policy, Systems, and Environmental Change

What is PSE Change? 

Policies take several forms such as laws, ordinances, regulations, and rules.  They can be formal or informal. Systems interventions are changes that impact all areas of an organization, institution or community, not just policies. Environmental interventions involve changes to the economic, social, or physical environment. Policy, systems, and environmental (PSE) change interventions have a great potential to improve a community's health by addressing socioeconomic factors and by making healthy choices more accessible, easier and the default choice through changing all three of the elements described above.

PSE is one of the three approaches outlined in the SNAP-Ed Guidance. Other approaches include Nutrition Education and Social Marketing. See how SNAP-Ed programs use PSE changes to make the heathier choice, the easier choice.
