Later on, concepts of temperament, character and personality get analysed. Then, the current approach to personality disorders according to the two models of DSM-5 is reported. The first model is included in the Section II of DSM-5; while in the Section III there exists a proposal for a so-called alternate model. The first one suggests a qualitative or categorical kind of approach to personality disorders, whereas the alternate model proposes a dimensional or quantitative kind of approach and aims to formulate, as well as a diagnosis for general alterations of the personological functioning, even a trait-based personality disorder diagnosis, which can be formulated when a personality disorder is there but doesn't fit criteria for a specific disorder. Ultimately, it can be so claimed: 1) diagnostic criteria of the first model are similar to those of DSM-IV with its respective strenghts and weaknesses, and namely high probability in diagnosis, where there, of personality disorder, yet insufficient sensitivity in the specification of the disorder; 2) the alternate model, despite criticism, thanks to the possibility of delivering a trait-based personality disorder diagnosis, seems to be more equipped both in the identification of the personality disorder and further specifications.
