Patterns of sex differences in negative symptoms and social functioning consistent with separate dimensions of schizophrenic psychopathology

In 220 schizophrenic twins, men had greater asociality-withdrawal and
poorer premorbid social competence than women but there were no sex
differences in symptoms, suggesting that negative symptoms and social
functioning reflect different processes in the development and
manifestation of schizophrenia and that they should be examined separately.
