The definition, classification and assessment of personality disorders (PDs) have attracted considerable debate for nearly 50 years. This paper attempts a comprehensive review of the instruments to assess all, or specific, individual disorders as described in DSM-5, including structured interviews and inventories. The review should be helpful for clinicians, researchers and also industrial and organizational psychologists, to screen and assess the personality pathology spectrum from subclinical manifestations to full blown personality pathology. A decision tree helpful to choose among the different measures is also provided.
