Classification models in health promotion and prevention. Possibilities and limits for conceptualising and evaluating projects and programs

摘要

Background. Various health classification models are used, particularly in the English-speaking world, to plan and evaluate projects and programs in the health sector. In this article, we critically examine two such models, which are currently being used in Switzerland.Methods. We use the Model for Results Classification (by Health Promotion Switzerland) and the Program Logic Model (by Sue Fun-nell) as two types of classification models in order to examine their application for planning and evaluating health projects and programs. In addition, we clarify the various implications of classification systems within the health field and show, on the basis of two case studies, problems arising from their application.Results. The models differ in their implicit assumptions and the extent to which theystructure health-related categories, as well as in the degree of explication of causal reasoning With regard to health outcomes. An application of one or the other model will bring with it different advantages and disadvantages.Conclusion. With regard to their limitations and inherent logic, classification models are nevertheless useful instruments to reduce complexity in planning and evaluating health projects and programs. Beyond that, they impose a negotiation between stakeholders with regard to making explicit health-related assumptions and goals.
