Gender differences in schizophrenia.
Lewine (Psychol. Bull., 90: 432-444, 1981) has proposed sex differences, specific to schizophrenics, in age at first psychiatric hospitalization, age at first reported symptoms, and premorbid social competence. To evaluate Lewine's hypothesis we collected data on 64 schizophrenic and 30 nonschizophrenic psychiatric outpatients. As no interaction between sex and diagnostic groups was found, our data failed to demonstrate sex differences specific and unique to schizophrenia. It is possible that Lewine's evidence is due to a cultural artifact.
