Moving beyond an exclusive focus on harm avoidance in obsessive compulsive disorder: considering the role of incompleteness.

Cognitive-behavioral conceptualizations of obsessive compulsive disorder (OCD) have predominantly viewed compulsions as being motivated by harm avoidance. However, sensations of things being incomplete or not "just right" may also underlie compulsions in OCD. Preliminary research suggests that distinguishing between harm avoidance and incompleteness in OCD may have practical utility, but the research on this topic is very limited to date. The current study further addressed the role of incompleteness in OCD. A confirmatory factor analysis provided evidence for harm avoidance and incompleteness as separate constructs in a student sample. Supporting the benefits of considering incompleteness in addition to harm avoidance, self-reported levels of both constructs were significantly correlated with all domains of OCD symptoms and perfectionism assessed. Further, some evidence for unique relationships was found (e.g., incompleteness with ordering and personally prescribed perfectionism; harm avoidance with obsessing). The role of incompleteness in OCD warrants greater attention.
