ABSTRACT
This chapter builds on the work of Summerfeldt, Kloosterman, Antony, & Swinson. There has been little outcome research on treatments for incompleteness Obsessive-Compulsive Disorder (OCD), with the exception of Tallis, who described four patients with cleaning related to perfectionism and urge to arrange objects "just so". All showed modest long-term therapeutic response to Exposure and Response Prevention (ERP) intervention compared with cognitive therapy or Serotonin Reuptake Inhibitor (SRI) medication. Cognitive therapy that involves reappraisal would therefore not focus on thoughts such as overestimation of threat, which is unlikely to be elevated, but on the individual's interpretation of emotional experience. Individuals with this OCD subtype report the urge to arrange or maintain objects and possessions in rigid ways, including preoccupation with order and symmetry. Sense of incompleteness is commonly associated with symptoms of symmetry, counting, repeating, slowness, and a more complicated comorbidity profile.
