Abstract

The Five Factor Obsessive Compulsive Inventory (FFOCI) was developed in part to facilitate a shift from the categorical classification of personality disorder to a dimensional model; more specifically, the five-factor model. Questions though have been raised as to whether obsessive-compulsive personality disorder can be understood as a maladaptive variant of FFM conscientiousness. The purpose of the present study was to provide a further validation of the FFOCI, as well as to compare and contrast alternative measures and models of OCPD. A total of 380 participants, including 146 oversampled for OCPD traits, were recruited from introductory psychology courses at the University of Kentucky. Administered were the FFOCI, measures of general personality (e.g.,, International Item Pool, 5-Dimensional Personality Test), trait scales associated with OCPD (e.g.,, workaholism, compulsivity, propriety), and alternative measures of obsessive compulsive personality disorder. All measures were administered via SurveyMonkey, a secure online survey service. Results supported the validity of the FFOCI, but also demonstrated substantive differences among the alternative measures of OCPD, particularly with respect to their relationship with FFM conscientiousness, antagonism, and introversion.
