Objective: To examine the factor structure of DSM‐IV criteria for obsessive compulsive personality disorder (OCPD) in patients with binge eating disorder (BED). Method: Two hundred and eleven consecutive out‐patients with axis I diagnoses of BED were reliably assessed with semi‐structured diagnostic interviews. The eight criteria for the OCPD diagnosis were examined with reliability and correlational analyses. Exploratory factor analysis was performed to identify potential components. Results: Cronbach's coefficient alpha for the OCPD criteria was 0.77. Principal components factor analysis with varimax rotation revealed a three‐factor solution (rigidity, perfectionism, and miserliness), which accounted for 65% of variance. Conclusion: The DSM‐IV criteria for OCPD showed good internal consistency. Exploratory factor analysis, however, revealed three components that may reflect distinct interpersonal, intrapersonal (cognitive), and behavioral features.
