The DSM-IV, classifies personality disorder in categories, identifying significant maladaptative personality traits and most of the diagnosis are validated. Those types of disorders are linked to cognitive and perceptual abnormalities that affect the lives of individuals.

In contrast with Rottman conclusions, a study from University of Kentucky found that clinicians could identify the respective personality disorders at a comparable success achieved with the DSM –IV diagnostic criterion when the maladaptative traits were provided to the clinicians. This study also found that the FFM is more useful in communicating with patients. (Glover, N. G., Crego, C., & Widiger, T. A. 2011, July 4).
There is a lack of studies that provide information about the clinical utility and acceptability of a dimensional model in the clinical practice and treatment decision, in contrast with a significant amount of clinical literature that provide recommendation for individual personality disorders, but only few documents about the clinical application of the dimensional model of classification. Some research support the reliability and validity of the FFM, however only four studies had been done to examine the ability and familiarity of clinicians when using the FFM. (Samuel, D. B., & Widiger, T. A. 2006). According to First and colleagues the importance should be placed on clinical utility, because a valid diagnostic manual that is not used properly in the clinical practice is unlikely
