Assessment of the outcomes of health intervention

In this article we discuss basic assumptions of health interventions with regard to their underlying concepts and selected strategies. Particularly, the lifestyle model of health promotion is presented and its consequences for health promotion and health interventions are discussed. Reference is made to two fields of interventions: prevention of cardiovascular diseases and worksite health promotion. It is concluded that health interventions have to clarify their concepts and strategies in detail before an evaluation of their outcomes can be carried out reasonably.
