Abstract:
Objectives:Social function deficit is known as a core feature of schizophrenia. This study aimed to investigate differences in empathic tendencies and theory of mind (ToM) skills between healthy controls and young individuals with schizophrenia, and to examine the associations between empathic tendencies, ToM skills and schizotypy, and executive function in schizophrenia.
Methods:Thirty patients with schizophrenia and 30 healthy controls were enrolled and assessed using the interpersonal relationship index (IRI; perspective taking, fantasy, empathic concern, and personal distress subscales), ToM-Picture Story Task (ToM-PST; sequence and cognitive questionnaire), Wisconsin schizotypy scale (revised physical anhedonia and perceptual aberration), and Stroop tests for empathic tendencies, ToM skills, schizotypy, and executive function.
Results:In individuals with schizophrenia, the IRI for perspective taking and ToM-PST score for cognitive function were lower, and the IRI for personal distress was higher than those in healthy controls. The IRIs for perspective taking and fantasy were related to revised physical anhedonia, and that for empathic concern was associated with revised physical anhedonia and perceptual aberration. The ToM-PST score for sequence was associated with the Stroop test score for schizophrenia.
Conclusion:These findings indicate deficits in empathic tendencies and ToM skills, which may be independently and primarily associated with schizotypy and executive function in young individuals with schizophrenia.
