An immediate conceptual advantage of considering personality disorders on a number of dimensions is that it provides answers to a number of the questions raised in the empirical evidence. Commorbidity for example can be seen as a result of the sharing of high levels on some of the personality factors. Many of the personality disorders have in common high levels of neuroticism, the differentiation between them can be seen in the other personality dimensions. One of the other main advantages of using the FFM is in realigning the way personality disorders are seen, in that they then become part of the spectrum on which normal personality is seen. In this way personality disorders are connected with 'normal' personalities and become more humanised.

While the FFM approach has provided a useful alternative to describing personality disorders, some researchers have valid criticisms. Clark (1993a) has suggested that the FFM approach has only provided mixed results, claiming that only some of the dimensions are related. In order to address some of these concerns, a different series of dimensions was built from the ground up. This contains three top level dimensions of negative temperament, positive temperament and disinhibition. Morey, Warner, Shea, Gunderson, Sanislow, Grilo, Skodol & McGlashan (2003) later tested these ideas by applying a personality test based on these dimensions to patients who had already been diagnosed with one of five primary diagnoses. The results showed that this model, like the FFM approach had some use in discriminating the personality disorders.
