Disordered personalities and disordered concepts

Abstract

This paper explores the uncertainties surrounding the diagnosis of personality disorder. Problems in relation to the reliability and validity of the diagnosis are examined, and their implications for our understanding of causation and decisions about intervention are discussed. Because of the difficulties surrounding the diagnosis, some suggestions are offered about an improved inter-disciplinary research agenda. Also because people with the diagnosis create extensive consternation and uncertainty for health and welfare professionals, some suggestions are made about providing an informed and supportive corporate response in localities. The paper concludes with a discussion of personality disorder and social policy.
