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