dc.description.abstractImpairment in social functioning has been widely described in obsessive-compulsive disorder (OCD). However, several aspects of social cognition, such as theory of mind (ToM), have not been substantially investigated in this context. This study examined cognitive and affective ToM in 40 OCD patients and 38 age-, sex-, and education-matched healthy controls (HCs) with the computerized Yoni task and a battery of neurocognitive tests. OCD symptom severity was assessed with the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Depressive and anxiety symptoms were also assessed. Compared to HCs, OCD patients performed worse on second-order affective condition trials, but not cognitive or physical condition trials, of the Yoni task; there were not group differences in any of the first-order condition domains. Second-order ToM performance of OCD patients was associated with estimated intelligence and working memory performance. After controlling for neurocognitive variables, the group difference in second-order affective condition performance remained significant. These findings indicate that the affective component of ToM may be selectively impaired in OCD patients and that the observed deficit is largely independent of other neurocognitive impairments and clinical characteristics.
