Özet

A growing body of research evidence documents the substantial associations between obsessive-compulsive disorder (OCD) and dissociation. This article describes the development and preliminary psychometric properties of the Van Obsessional Dissociation Questionnaire (VOD-Q). Obsessional dissociation is defined as a tendency to dissociate in reaction to distressing, unwanted and intrusive thoughts, images and impulses. The screening tool is conceptualized to tap obsessional dissociation across three dimensions: obsessional absorption, obsessional depersonalization/ derealization and obsessional amnesia. The VOD-Q, the Padua Inventory-Revised (PI-R), the Dissociative Experiences Scale (DES), and the Obsessive Belief Questionnaire (OBQ-44) were administered in this study. The results showed that the VOD-Q had excellent test-retest reliability (ranging from 0.73 to 0.90) and internal consistency (ranging from 0.90 to 0.97). The VOD-Q total and subscale scores were significantly associated with measures of obsessive-compulsive symptoms and dissociative experiences. OCD patients scored significantly higher on the VOD-Q than community participants. Based on the present findings, the VOD-Q appears to be a reliable and valid instrument for the measurement of obsessional dissociative experiences.
