영문 초록

Objectives Theory of mind (ToM) is the ability to conceptualize other people’s mental states in order to explain their behavior. This study compared the ToM ability of schizophrenia patients, their first-degree biological relatives, and healthy controls. Methods ToM animation test was administered to schizophrenia patients (N=28), their healthy first-degree relatives (N=26), and healthy controls (N=28). The Korean version of schizotypal personality questionnaire (SPQ) was used to assess the schizotypal personality trait of all three groups. Results Schizophrenia patients and their first-degree relatives showed decreased accuracy on ToM animation test compared to healthy controls [F(2,78)=29.75, p<.001]. Additionally, first-degree relatives performed worse than the control group and better than schizophrenia patients. First-degree relatives had similar SPQ scores compared to healthy controls but showed decreased ToM accuracy compared to healthy controls. Conclusion ToM deficits in schizophrenia patients are apparent. The ToM deficit in first-degree relatives of schizophrenia patients raises the possibility that ToM deficit may be a endophenotype for schizophrenia pathology
