The alternative model of personality disorders introduced in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders provides a diagnostic system that is expected to correspond to the well-known categorical approach of personality disorder diagnoses. The current study aims to improve knowledge about the relationship between pathological personality traits and their corresponding personality types. A Brazilian sample of 1,162 people took part in this study. The results point to some level of continuity between the two models when the variables were treated as dimensional. Contrariwise, there is a lack of strong scientific evidence to justify the maintenance of the categorical approach. We recommend the exclusion of the categorical approach from personality disorder diagnosis systems.
