In order to work effectively with people with personality disorders it is important that Mental Health Social Workers (MHSWs) have a clear understanding of trauma and its impact on the person. It is also important that they have good relational skills and the support of the team and organisation. Drawing on an analysis of the similarities (and differences) in service user and MHSWs' perspectives, the book outlines the further skills, knowledge and conditions that will help them to make a more effective contribution to the support of those with personality disorder.  The book will appeal to qualified Mental Health Social Workers and those on Post-Qualifying Programmes because, uniquely, it explores personality disorder from a social work perspective.
