Note: aDiagnoses with an affective component included six schizoaffective, one major depressive disorder with psychotic features, and one bipolar disorder with psychotic features. Note that traditional categorization of affective/non-affective psychosis would classify schizoaffective disorder as a non-affective disorder, in which case the affective disorder subgroup would be n = 2 and too small to support a subgroup analysis (see text for further discussion).
bNon-affective diagnoses included 19 schizophrenia, 5 schizophreniform, 2 delusional disorder, 14 unspecified schizophrenia spectrum or other psychotic disorder, and 1 other specified schizophrenia spectrum or other psychotic disorder.
cDiagnosis could not be confirmed in a minority of cases in which the SCID could not be administered.
