Impairment of theory of mind in patients in remission following first episode of schizophrenia

The aim of this study was to investigate theory of mind (ToM) ability in patients in remission after the first episode of schizophrenia. A ToM task which contained four pictures was given to 30 patients with schizophrenia in remission and 30 matched healthy controls. Patients with schizophrenia in remission showed statistically significant impairment in the ToM tasks. ToM impairment was not correlated with psychiatric symptoms. Thus, ToM deficit in schizophrenia may be a trait marker.
