Diagnostic Assessment of Schizophrenia

  • Oliver Freudenreich
Chapter
Part of the Current Clinical Psychiatry book series (CCPSY)

Abstract

Diagnosis matters as it guides treatment with the goal of improving prognosis. In this chapter, I review how to make a clinical diagnosis of schizophrenia with the help of diagnostic criteria. Diagnostic errors leading to a missed or mistaken diagnosis of schizophrenia are discussed. In addition, this chapter describes the elements of a comprehensive assessment of schizophrenia, beyond the categorical diagnosis of schizophrenia. For treatment goals and outcomes, clinicians need to assess psychotic and nonpsychotic symptom clusters (dimensions of schizophrenia), function, and quality of life. Rating scales can inform and enhance clinical care.

New York: Oxford University Press; 2019. – Published originally in 1974, this book (particularly the preface to the first edition which is included in the 7th edition) is a must read for any psychiatrist who wants to critically examine the diagnostic validity of many of our current psychiatric diagnoses. The late Donald Goodwin and Samuel Guze (together with Eli Robins and George Winokur) belonged to an influential group of psychiatrists at the University of Washington in St. Louis that aligned psychiatric diagnosis with medical practice by introducing diagnostic criteria, ultimately resulting in the publication of DSM-III in 1980.Google Scholar
