Van der Linden, M. 2009 Anatomy of the White Bear Suppression Inventory (WBSI): A review of previous findings and a new approach Journal of Personality Assessment 91 323-330 thought suppression, intrusion, French WBSI, questionnaire, anxiety, depression, item response theory, SCAS <div align="justify">The White Bear Suppression Inventory (WBSI; Wegner &amp; Zanakos, 1994) was originally designed to assess people’s inclination toward thought suppression. This article provides a detailed review of previous findings on the structure of this instrument and presents a study that took a new statistical approach: It involved an exploratory factor analysis of the French WBSI using the weighted least squares mean and variance estimator, as well as parametric item response theory analyses. Results clearly supported a 2-factor structure with a “suppression” and an “intrusion” dimension. Follow-up regression analyses revealed that intrusion significantly predicted anxiety and depression scores, whereas suppression did not. </div>
