The psychodynamics of psychosis

This article outlines common psychodynamics in psychosis. We consider psychosis as a response to unbearable aspects of reality and illustrate how psychodynamic concepts of psychological defence can be used as a framework for understanding this. We also present a psychodynamic approach to understanding the development of psychosis, using the stress–vulnerability model, and discuss interpersonal dynamics in psychosis, particularly their relevance to therapeutic relationships and to interactions between patients and their families. The perspectives presented are intended to complement and enrich other frameworks rather than compete with them.
