Thirty‐nine patients with schizophrenia, diagnosed according to DSM‐III‐R, who were under 15 years of age, were studied in two groups; 16 subjects with obsessive‐compulsive symptoms during the prodromal phase, and 23 with no obsessive‐compulsive disorders. The group with obsessive‐compulsive symptoms during the prodromal phase was characterized by a higher ratio of males, higher incidences of perinatal and brain computed tomography (CT) abnormalities, fewer hereditary factors, longer duration of the prodromal phase, and a higher incidence of insidious onset and negative symptoms compared with the group without such prodromal symptoms. Schizophrenic patients with obsessive‐compulsive symptoms during the prodromal phase were clinically distinct from those without, which suggests the possibility of subtype categorization.
