Summary

Insight is a complex phenomenon that can be interpreted according to a dimensional model. Given the controversial data of insight in obsessive–compulsive disorder (OCD), our study aimed to investigate insight in an Italian sample of patients with OCD by means of the specific item on the Yale–Brown obsessive–compulsive scale (Y-BOCS) and to explore the possible correlations between it and clinical features. One hundred and seventeen out-patients with a DSM-IV diagnosis of OCD and different comorbid psychiatric disorders were included in the study and assessed by means of the Y-BOCS, Hamilton rating scale for depression (HRSD) and the global clinical impression. The results showed that almost 50% of the patients had an excellent level of insight and 15% had a little or no insight. No correlation between levels of insight and clinical features was observed, except for a negative trend with the presence of somatic obsessions. In addition, a trend towards a lower level of insight was observed in those bipolar patients with a positive history of repeated manic or hypomanic episodes. Further studies seem to be necessary in order to establish whether or not OCD patients with poor insight represent a distinct sub-group of patients.
