Members of the WPA’s Section of Personality Disorders are working to advance knowledge and understanding of the role that personality and personality dysfunction play in influencing mental health and wellbeing. Members of the group have contributed to the revised system for classifying personality disorder that led to ICD-11. In addition, members of the group organise presentations and seminars at WPA meetings and aim to foster international collaborations that promote education, research and service developments that benefit people with personality disorder.
