Role of knowledge in public health and health promotion policy change

A framework of policy development is presented that identifies the role various forms of knowledge can play in the policy formation process. The framework is based upon the premise that public health and health promotion issues should be addressed within an analysis of policy change that considers concepts of interactive and critical knowledge in addition to scientific knowledge. Progress in developing meaningful health policy will require accepting the validity of these various forms of knowledge and developing frameworks that see experts and citizens working together to develop and achieve public health and health promotion goals.
