Evaluation seems to be a widely accepted scientific tool for the description of activities (interventions) and their effects on the addressed population. This includes the health sector as many others. It seems to be reasonable to extend evaluative questions also into the self help activities of the population. But this does not mean that there are no ‘specifics’ to be considered in this context. It is the attempt of this paper to explore some of these ‘specifics’ of evaluative research in the self help field.
