Reappraising insight in psychosis

Abstract

BackgroundMany patients suffering from psychosis are unaware of their disorder and symptoms.AimsTo investigate whether insight changes with time, and how it relates to patients' psychopathology, and to examine the correlations between insight scales in patients with psychoses.MethodSeventy-five consecutively admitted in-patients with schizophrenia, affective disorder with psychotic symptoms, or schizoaffective disorder were examined after remission of an acute episode and at follow-up (>6 months). Three different scales were used to assess insight.ResultsTo some extent, insight into past episodes improved over time in patients with psychosis, regardless of diagnosis. Few significant relationships between insight and psychopathology remained stable at follow-up. The higher the negative and disorganisation dimensions at baseline, the less did attitudes to treatment vary when tested at follow-up. No predictive value for variability of psychopathological dimensions was found for insight dimensions. The insight scales used were highly intercorrelated, suggesting that they measure the same construct.ConclusionsInsight and psychopathology seem to be semi-independent domains.
