Stability in basic self-disturbances and diagnosis in a first treated psychosis: A seven year follow-up study

Abstract

Background: Basic self-disturbances (BSDs) are considered core features of schizophrenia spectrum disorders, and are present in the prodromal, early psychotic and chronic phases. Considerable levels of BSDs are also present at first treatment in some patients with psychotic disorders outside the schizophrenia spectrum. There is limited knowledge about the stability of self-disturbances over time. Aim: To explore the stability of BSDs in a seven-year follow-up of first treatment patients, and the association between baseline levels and changes in BSDs and diagnostic changes at follow-up. Method: Longitudinal study of 56 patients (35 schizophrenia and 21 non-schizophrenia) recruited at their f..
