Schizotypal PD (DSM-5)
In the Introduction to , Kupfer et al. (2002) questioned the validity of traditional categorical approaches to the diagnosis of mental disorders. Epidemiological and clinical studies showed high rates of co-morbidity between disorders and short-term diagnostic instability. No laboratory marker had been found to be specific for any DSM-defined syndrome and treatment specificity for different types of disorders was rare. Rounsaville et al. (2002) then explicitly focused on personality disorders (PDs): “There is a clear need for dimensional models to be developed and their utility compared with that of existing typologies in one or more limited fields, such as personality.”
Antisocial PD (DSM-5)
In the Introduction to , Kupfer et al. (2002) questioned the validity of traditional categorical approaches to the diagnosis of mental disorders. Epidemiological and clinical studies showed high rates of co-morbidity between disorders and short-term diagnostic instability. No laboratory marker had been found to be specific for any DSM-defined syndrome and treatment specificity for different types of disorders was rare. Rounsaville et al. (2002) then explicitly focused on personality disorders (PDs): “There is a clear need for dimensional models to be developed and their utility compared with that of existing typologies in one or more limited fields, such as personality.” The fundamental problem with the PD diagnostic system in DSM-III, III-R, and -IV is that it takes an essentialist “top-down” approach (Kendler, 2009), based on the assumption that there are a small number of personality types, each of which has a fundamental nature.APA DSM-V
