The Williamsburg conference on personality disorders: What have we learned?

This group of papers from the 1990 Williamsburg Conference demonstrate how much we have learned about personality disorders in the last decade; the methods used in the study of depression, schizophrenia, anxiety, and other Axis I disorders have begun to be applied in investigations of personality disorders. Such methods include semistructured interviews, self-report inventories, family and twin studies, longitudinal research, and biological and psychological measures. Both psychotherapeutic and pharmacological treatments that come from research and practice with Axis I disorders, have also begun to be applied to the personality disorders.
