This book represents a comprehensive collection of theoretical and empirical work at the nexus of clinical and forensic psychology written by world-renowned experts in the field. It is among the first books in the field to focus entirely on clinical psychological science applied to the understanding and treatment of offending. Part I addresses the main theoretical and clinical models used to explain and predict antisocial behavior, spanning biological, cognitive, experimental, individual differences, and interpersonal perspectives. Part II focuses on forms of psychopathology associated with an increased tendency to offend, with the emphasis on describing the clinical constructs most relevant for forensic psychology. Each chapter describes the clinical characteristics of one form of psychopathology, their assessment, their links with antisocial behavior, and treatment considerations. Part III focuses on different types of offense or offender groups as starting points. This perspective has relevance since many criminal justice and forensic mental health systems allocate offenders to interventions based on their index offense (or history of offenses). Finally, Part IV addresses the application of clinical psychology in the service of assessment and treatment in forensic settings. It includes the state of the art on diagnostic and risk assessment, as well as both widely used and recently developed interventions. This book is an excellent resource for students at both Bachelor's and Master's level, while also representing a comprehensive handbook for experienced researchers and practitioners.
