Abstract
The focus on recent advances in the neurobiology of schizophrenia has pushed aside the psychological understanding of the person with schizophrenia for several decades. However, a useful functional psychology of schizophrenia (in distinction to a psychological approach to symptoms) remains clinically important for several reasons: it is a core part of the bio-psycho-social formulation; it helps us understand and connect with persons with schizophrenia; and it provides a framework by which to organize our treatment efforts (both psychotherapeutic and particularly biological), which can improve adherence and outcomes. A coherent psychological model (the deficit model) based on object relations theory best explains all the biological, psychological, clinical, and sociocultural factors relevant to the understanding and treatment of persons with schizophrenia. A better understanding of a coherent psychology of persons with schizophrenia and provision of psychotherapies improves both the biological and psychotherapeutic treatment of persons with schizophrenia.
