چکیده (انگلیسی):

Although borderline personality disorder (BPD) and schizophrenia (SZ) are notably
different mental disorders, they share problems in social cognition—or understanding
the feelings, intentions and thoughts of other people. To date no studies have directly
compared the social cognitive abilities of individuals with these two disorders. In this
study, the social cognitive subdomain theory of mind was investigated in women with
BPD (n = 25), women with SZ (n = 25) and healthy women (n = 25). An ecologically
valid video-based measure (Movie for the Assessment of Social Cognition) was used.
For the overall score, women with SZ performed markedly below both healthy women
and women with BPD, whereas women with BPD did not perform significantly different
compared to the healthy control group. A statistically significant error type  group
interaction effect indicated that the groups differed with respect to kind of errors. Whereas
women with BPD made mostly overmentalizing errors, women with SZ in addition
committed undermentalizing errors. Our study suggests different magnitude and pattern
of social cognitive problems in BPD and SZ
