Prevalence of DSM-IV-TR diagnosis by group.

This figure compares the prevalence of DSM-IV-TR-diagnosed psychosis between a general psychiatric sample (ÆSOP study – psychosis)¹⁸ and the ASD and comorbid psychosis (ASD–P) group. ‘Schizophrenia’ here includes schizophrenia, schizophreniform and schizoaffective disorders. Affective psychosis includes those with major depressive episode with psychotic features, manic episode with psychotic features and bipolar disorder with psychosis. ‘Other psychosis’ includes psychotic disorder not otherwise specified, which was present in 52% of the ASD–P sample. a. Of the full ASD–P data-set (n = 75), four had a DSM-IV-TR diagnosis of major depressive episode without psychotic features and were thus excluded from this comparison.
