Abstract

In this chapter we discuss the diagnosis, etiology, and pathology of personality disorders. We begin with a general discussion of the definition, clinical importance, and assessment of personality disorders. We then discuss each of the 10 DSM-IV personality disorders (i.e., paranoid, schizoid, schizotypal, antisocial, borderline, histrionic, narcissistic, avoidant, dependent, and obsessive-compulsive), considering in particular their description, epidemiology, and etiology. We then discuss the latest status of the controversial proposals for personality disorders in the fifth edition of the American Psychiatric Association (DSM-5). We conclude with a description and understanding of the personality disorders from a dimensional trait model, the five factor model (FFM). The dimensional trait model proposed for DSM-5, as well as the traits proposed for each individual personality disorder, are closely aligned with the FFM. However, we suggest how the personality disorder nomenclature should be further revised to provide a truly integrative model of normal and abnormal personality.
