Objective: While recent studies have found deficits in theory of mind (ToM) skills in individuals at ultra-high risk (UHR) for psychosis, empathic tendencies in these subjects remain unclear. The presence of high schizotypy and compromised executive functions, which are found in UHR individuals, would affect ToM skills and empathic tendencies. We investigated the ToM skills and empathic tendencies of UHR individuals and examined their relationship with schizotypy and executive function. Methods: This study included 28 UHR individuals and 28 age- and sex-matched healthy controls. All participants completed a self-reported empathic scale (Interpersonal Reactivity Index) and the Wisconsin Schizotypy Scales. Additionally, the ToM Picture Stories Task and Wisconsin Card Sorting Test were conducted. Results: UHR individuals showed a trend toward lower self-reported empathic tendencies; however, there were no differences in ToM skills between the two groups. Of the four subscales of the IRI, only empathic concern showed a significant difference between the two groups. Empathic concern was inversely associated with negative schizotypy. Conclusion Our findings suggest that UHR individuals show relatively preserved cognitive empathy but compromised emotional empathy. Furthermore, in UHR individuals, the empathic concern subscale of the IRI was associated with negative schizotypy, while ToM skills were related to positive schizotypy and executive function.

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.
