This paper employs the methodological framework of linguistic analytic philosophy to explore the conceptual issues arising from a study of the different models of disorder implicit in five groups of stakeholders concerned in the community care of people with a diagnosis of long-term schizophrenia. Linguistic analysis, gives a precise fix on the nature of the practical difficulties presented by such models, suggests a powerful heuristic for displaying and comparing models, is the basis of a methodology which is neutral as between (...) users and providers of services, provides an intuitively powerful way of understanding the results of work of this kind, and facilitates the translation of research into practice.
