This book examines the care of the mentally disordered offender in the community from a number of perspectives: the social, administrative, and clinical context; clinical aspects of care; and the relationships between psychiatric services for mentally disordered offenders and other agencies. It incorporates recent developments in treatment and policy, including an international analysis of the use of community treatment orders, which remain controversial and divide opinion. In the United States, efforts to improve treatment have focussed on improving continuity of care between prison and the community, and the book examines US jail and prison policy. Current UK health policy as applied to the mentally disordered offender is explained. Risk and risk thinking is a theme that runs through the book and is considered in terms of its effect on society, its influence on policy, and in terms of how risk assessment is applied in everyday clinical practice. Developments in psychodynamic psychotherapy and cognitive treatments for mentally disordered offenders are discussed, including consideration of the risk-need-responsivity model, which has become increasingly influential. The treatment of sex offenders and personality disorder offenders is considered specifically, as is pharmacological therapy. Most mentally disordered offenders are managed in the community by the Community Mental Health Team (CMHT). The role of the CMHT and its interface with specialist community forensic teams is considered, as is the interaction between mental health services and other agencies and the legal context within which they operate.
