Objective: To test the diagnostic constructs implied by DSM‐IV Axis‐II personality disorders by examining relationships between different combinations of DSM‐IV criteria. Method: Confirmatory factor analysis was used to test the borderline, schizotypal, avoidant and obsessive‐compulsive personality disorder constructs in a large treatment‐seeking sample ( N =668) from a multisite study. A model based on the three DSM‐IV Axis II clusters was also tested. Both models were tested against a unitary ‘generic’ model constructed from four criteria sets combined. Results: Goodness‐of‐fit for both the three‐cluster and four disorder models was significantly better than the unidimensional model, and the four‐disorder model was significantly better than the three‐cluster model. Results were replicated using data from 2‐year follow‐up obtained by interviewers blind to original Axis II diagnoses at baseline. Conclusion: Support is provided for the DSM‐IV disorder‐level classification for schizotypal, borderline, avoidant and obsessive‐compulsive personality disorders in a treatment‐seeking sample.
