Successful demonstration of the effects of health promotion calls for systematic documentation and comparison of the outcome of different measures and projects. A model has been developed in the form of an outcome categorisation system for this purpose and is presented here. The model includes four categories covering the intermediate outcomes of health promotion measures, and three categories for outcomes at the level of health determinants (conditions necessary for health). Each category includes three to four sub-categories, for which examples of possible indicators are presented. The model can be applied both in the planning and in the evaluation stage of a project. This makes it possible for health promotion agencies and institutions responsible for funding and promotion to obtain a general overview of the outcome of their work.
