Assessment of Defense Styles and Mechanisms in Iranian Patients Suffering from Obsessive Compulsive or Panic Disorders versus Normal Controls using Persian Version of Defense Style Questionnaire-40

The aim of this study was to compare defense styles and mechanisms in adult patients suffering from obsessive-compulsive disorder (OCD), and panic disorder (PD) with normal subjects in Iran. Defensive patterns of 22 patients with OCD, 28 patients with PD and those of 116 normal individuals (as a control group) were assessed using the Farsi version of Defense Style Questionnaire-40 (DSQ-40). The content validity of this questionnaire was done prior to the initiation of the present study. Both groups of patients with OCD or PD used more immature and less mature styles compared to the control group. No significant difference was observed in the use of neurotic style between the two groups. It is suggested that immature defenses may have an important role in the pathogenesis of OCD and PD.
