Available evidence about the relationship between poor insight and other clinical characteristics in patients with obsessive-compulsive disorder (OCD) is inconclusive and conflicting. There is also a paucity of data on the long-term course and treatment outcome of OCD patients with poor insight. The present study reports the findings of a relatively large sample (n = 106) of outpatients fulfilling DSM-IV criteria for OCD, treated with serotonin reuptake inhibitors (SRIs) and prospectively followed LIP for 3 years. Baseline information was collected on demographic and clinical characteristics, using standardized instruments. insight was assessed by means of the Brown Assessment of Beliefs Scale (BABS). Eighty-three patients were followed prospectively and evaluated systematically by validated measures of psychopathology. Compared to their good insight counterparts, the CCD patients with poor insight (22%) showed a greater severity of obsessive-compulsive and depressive symptomatology: an earlier age at onset; a higher rate of schizophrenia spectrum disorder in their first-degree relatives; a higher comorbidity with schizotypal personality disorder. During the follow-up period, poor insight OCD patients were less likely to achieve at least a partial remission of obsessive-compulsive symptoms: required a significantly greater number of therapeutic trials; received more frequently augmentation with antipsychotics. The results suggest that the specifier poor insight helps to identify a subgroup of patients at the more severe end of OCD spectrum, characterized by a more complex clinical presentation, a diminished response to standard pharmacological interventions, and a poorer prognosis. Further research is needed to identify alternative strategies for the management of these patients. (C) 2009 Elsevier Inc. All rights reserved.
