ABSTRACT
Kingdon and Turkington (1999) noted the diverse nature of the phenomenology of schizophrenia and argued for the existence of separate syndromes within the schizophrenia spectrum. They suggested five subgroups based on a review of cognitive behavioural therapy (CBT) notes and case formulations. These postulated subgroups included sensitivity disorder, catatonia, anxiety psychosis, drug-induced psychosis and traumatic psychosis (see Table 10.1). It was suggested by Kingdon and Turkington (1999) that the basic CBT for psychosis manuals would have to be adapted with new techniques to work with each subgroup.
