More informative comparative validity studies would not only contrast the FFM to the DSM-IV-TR, but the ability of the FFM relative to alternative dimensional models of general personality structure. In addition, even if the FFM obtains more validity than a respective alternative model (e.g., Mullins-Sweatt & Widiger, 2007b), it is possible that the most valid dimensional model of general and universal personality structure would be obtained through an integration of the alternative choices.
