To elucidate the relationships between insight and alexithymia in a sample of adult outpatients with obsessive-compulsive disorder (OCD).112 adult outpatients with OCD were tested. Severity of OCD was assessed with the first 10-items of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and score for item # 11 on the Y-BOCS was considered as a measure of insight. Alexithymia was measured with 20-item Toronto Alexithymia Scale (TAS-20). Additional measures were Maudsley Hospital Obsessive Compulsive Inventory (MOCI) and Montgomery Asberg Depression Rating Scale (MADRS).Of the patients, 29.5% showed poor or no insight. Patients with poor or no insight were more alexithymic than patients with excellent, good and moderate insight. TAS-20 total score and subfactors positively correlated with score for item # 11 on the Y-BOCS, severity of OCD and MADRS scores. In stepwise regression model, MADRS scores, factor 3 of TAS-20 (Externally Oriented Thinking), somatic and hoarding-saving obsessions were significantly associated with lower insight.Results show a relationship between poor or absent insight and high alexithymia levels in OCD patients.
