Abstract
Obsessive-compulsive personality disorder (OCPD) has been subject to numerous definition and classification changes, which has contributed to difficulties in reliable measurement of the disorder. Consequently, OCPD measures have yielded poor validity and inconsistent prevalence estimates. Reliable and valid measures of OCPD are needed. The aim of the current study was to examine the factor structure and psychometric properties of the Pathological Obsessive Compulsive Personality Scale (POPS). Participants (N = 571 undergraduates) completed a series of self-report measures online, including the POPS. Confirmatory factor analysis was used to compare the fit of unidimensional, five factor, and bifactor models of the POPS. Convergent and divergent validity were assessed in relation to other personality dimensions. A bifactor model provided the best fit to the data, indicating that the total POPS scale and four subscales can be scored to obtain reliable indicators of OCPD. The POPS was most strongly associated with a disorder-specific measure of OCPD, however there were also positive associations with theoretically disparate constructs, thus further research is needed to clarify validity of the scale.
