There is a growing interest in ToM performance among individuals with psychiatric disorders. However, the difference and the performance level between different diagnoses are unclear. Here, we compared the ToM abilities of schizophrenia (SZ), schizoaffective (SZaff), and borderline personality individuals (BPD) with healthy individuals. Individuals with SZ (n = 44), SZaff (n = 11), BPD (n = 11), and healthy individuals (n = 18) were recruited from Mazor Mental Health Center. All groups underwent the Reading Mind in the Eyes (RME) and the Faux Pas recognition test (FB) to assess TOM ability and completed empathy and autism questionnaires. The current results show that the three diagnostic groups performed worse in the RME and FB test compared to healthy individuals. However, women with BPD performed significantly better in ToM tasks than women with SZ and SZaff. Individuals with schizophrenia and BPD scored higher on the autism spectrum questionnaire, while all the diagnostic groups scored lower on the empathy quotient scale than healthy individuals. Finally, a positive correlation was found between ToM ability and empathy. Strikingly, our findings challenge the ability to use ToM as a differential clinical diagnostic tool, especially among men, and strengthen the correlation between decreased empathy and impaired ToM.
