Abstract: | Background: It is known that obsessive-compulsive disorder (OCD) patients with poor insight display more severe neuropsychological impairments than other patients with OCD. There are limited studies of OCD and theory of mind (ToM).Aim: To investigate ToM skills in patients with OCD and the relationship between insight and ToM skills by comparing OCD patients with good and poor insight.Methods: Eighty patients with OCD and 80 healthy controls completed the structured clinical interview for DSM-IV axis I disorders, the Yale Brown Obsessive-Compulsive Scale, the Beck Anxiety and Beck Depression Inventories, and the Brown Assessment of Beliefs Scale. To assess ToM skills, first- and second-order false-belief tests, a hinting test, a faux pas test, a reading the mind in the eyes test, and a double-bluff test were administered.Results: Patients with OCD had poorer ToM abilities than healthy controls. All ToM scores were significantly lower in the poor insight group than in the good insight group (p?.001). A significant negative correlation was found between the BABS-total scores and all the ToM test mean scores (p?.05).Conclusions: The finding of significantly lower ToM skills in OCD with poor insight than in OCD with good insight may contribute to the idea of OCD with poor insight being a subtype with different clinical and neuropsychological characteristics. |
