Mentally disordered offenders (MDOs) have dominatd the recent political agenda for mental health care emphasised by cases such as those of Christopher Clunis and Michael Stone. Yet successive governments have constrained the development of all health and social services by the requirement that they must be demonstrated as capable of benefiting those to whom they are applied. This book analyses the development of government policy for services for MDOs since the important Butler report in 1975 and provides a theoretical framework for adjudging research which purports to demonstrate a need and outcome. Finally, it emphasises the subjective and value-laden nature of all needs assessments and their interpretation and poses the crucial questions of whose need it is that we address through MDO services, those of the patient or of society. This book will be valuable to clinicians and researchers working in mental health services, policy-makers, service commissioners and managers.
