Abstract

There has been renewed interest into affective symptoms and psychological approaches to schizophrenia and other psychosis, yet no in-depth investigation as to the course, consequences or indeed psychological causes of depression in a phase specific manner in the important first episode. Our understanding of risk and aetiological processes in psychotic illness will only advance once we accurately identify the “end phenotype” of psychotic illness. This series of studies investigates the course of depression in first episode psychosis, its significance in terms of suicidal thinking, and relation to both diagnosis and other symptom domains. Depression in the acute and post psychotic phases is explored, through the importance of the awareness and appraisal of positive symptoms, and diagnosis itself. Significant findings include a pervasive nature of depression throughout the course of first episode psychosis, the predictive nature of prodromal depression and the high prevalence of suicidal acts. Appeasement and engagement with voices, subordination to persecutors and the (ineffective) use of safety behaviours drive a position of entrapment, demoralization and a lack of control. In addition negative illness appraisals are stable and may vary between cultural groups. Implications are explored, in terms of clinical practice, aetiological pathways, potential treatments and intervention strategies
