Abstract

Salkovskis' (1989) cognitive-behavioural model of obsessive-compulsive disorder (OCD) posits that appraisals of intrusive thoughts that lead to symptoms of OCD are those in which the person perceives him or herself to be responsible for the occurrence of the intrusion and/or the perceived catastrophic outcomes (content) associated with the unwanted thought. Since Salkovskis' contribution, other cognitive theorists have acknowledged the importance of the appraisals (interpretations) of intrusive thoughts in the development and maintenance of OCD. The Obsessive Compulsive Cognitions Working Group (OCCWG) created the Interpretation of Intrusions Inventory (III), a self-report scale containing three subscales (Control of Thoughts, Importance of Thoughts, and Responsibility). Each subscale is designed to capture different types of appraisals of mental intrusions. Three hundred and seven undergraduate students at the University of Windsor completed the III. To provide an independent replication of the factor structure of the III, and to assess the hypothesis that its items are better conceptualized as representing a two-factor structure (of items that assess occurrence and content) related to responsibility appraisals, exploratory and confirmatory factor analyses were conducted.
