This record study was the second of a series on the group of schizoaffective and related psychoses. Data were presented for two groups of inpatients. Both manifested at least two types of thought and behavior disorders, but only the first group had, at the same time, sufficient affective symptoms to meet clinical research criteria for depression or mania. The most important similarities for both groups were the high frequencies of chronic illness, delusions of persecution, and auditory hallucinations. There would appear to be little doubt that patients in the second group have paranoid schizophrenia. On the other hand, patients in the first group cannot be regarded as having typical paranoid schizophrenia because of having met criteria for affective disorder, and because the chronic course was manifested substantially more by affective symptoms than the second group.
