While the notion of insanity and the fact that it is unfair to hold "mentally impaired" people fully and criminally responsible for their actions has a long history, the concepts associated with criminal responsibility are still complex and difficult to define. In recent years, the field has developed a greater consensus regarding essential data collection methods, as well as how to manage the type of reasoning that is required in fitting data to the legal definitions. This volume offers guidance for the forensic mental health examiner, based on tradition as well as the latest developments for improving practice in criminal responsibility evaluations.
