Insight and major mental illness: an update for clinicians

Abstract

This article will concentrate on insight into serious mental disorder. Not psychoanalytic insight – nor indeed, the insight all of us have, to a greater or lesser extent, into our own attitudes, motives and behaviour – but the insight which patients with psychosis have into their mental pathology. This is no longer considered an all-or-none phenomenon, but rather a dimensional one, so that subjects can have different levels of awareness into their illness. The suggestion was first mooted by Aubrey Lewis (1934) in his seminal work on insight. Conceptual exploration of insight has been activated in the past decade and is proceeding in parallel with the construction of special scales to measure insight and research into its cognitive, biological, social and cultural basis.
