Patterns of Axis-II comorbidity in a Turkish OCD sample

OBJECTIVE Obsessive-compulsive disorder (OCD) patients frequently present with Axis-II disorders, particularly Cluster C (anxiety spectrum) and Cluster A (schizophrenic spectrum) personality disorders. The present study examined patterns of Axis-II comorbidity in a Turkish OCD sample. In addition, we explored the impact of personality disorder symptoms on OCD-symptom severity and symptom profile. METHOD Structured psychiatric interviews and self-report measures of OCD symptoms and Axis-II disorders were administered to patients with OCD and control subjects. RESULTS Patients with OCD obtained significantly higher scores on measures of Cluster A and Cluster C personality disorders. Patients with OCD also achieved significantly higher scores on the BPD Subscale; however, they did not obtain significantly higher scores on other Cluster B subscales. Group differences on measures of Cluster A and C disorders were marked. CONCLUSIONS Findings are consistent with prior work demonstrating an increased incidence of Axis-II disorders among patients with OCD.
