The book is divided into four parts: Criminal Justice Assessments, Offenders with Mental Disorders, Family Violence, and Policy and Practice. Criminal Justice Assessments covers approaches to risk assessment and assessment techniques for different sub-groups of offenders, while Offenders with Mental Disorders focuses on special groups of offenders. Family Violence examines child abuse and domestic violence and Policy and Practice looks at behavioural science support in police investigations, the ethical implications of risk assessment and the psychologist as expert witness.
