Personality Disorders

This chapter describes the proposals that were made for Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the revisions for International Classification of Diseases (ICD-11). It provides an alternative model for the diagnosis and classification of maladaptive personality functioning, the Five-Factor Model (FFM), with which the DSM-5 proposals and ICD-11 revisions were coordinated. The chapter discusses, more specifically, five of the DSM-5 personality disorders -- antisocial, narcissistic, borderline, schizotypal, and dependent -- including their understanding from the perspective of the FFM. There are a number of advantages of an FFM of personality disorder. The dimensional trait model addresses the many fundamental limitations of the categorical system. Antisocial personality disorder (ASPD) has been included within every edition of the DSM. One might even characterize ASPD as the prototypic personality disorder as the term “psychopath” originally referred to all cases of personality disorder.
