The first reported case of CBT for schizophrenia occurred in 1952 when Aaron Beck described successful treatment of delusions in a patient with schizophrenia (A. T. Beck 1952). However, systematic exploration of the possible role of CBT in treatment of schizophrenia and other psychoses did not begin until the early 1990s (Kingdon and Turkington 1991, 1994; Tarrier et al. 1993). Over the past two decades, several books have been published that detail methods for performing CBT with psychotic patients (Chadwick et al. 1996; Kingdon and Turkington 1994, 2002, 2005); numerous outcome studies have been completed (reviewed in Chapter 8); and CBT applications for schizophrenia have been gaining increased acceptance. In the United Kingdom, where much of the research on CBT for psychoses has been conducted, the National Institute for Clinical Excellence (2002) guidelines for treatment of schizophrenia recommend a course of CBT for all patients who have this condition.
