This state-of-the-art book reviews the contribution of psychology to the explanation of criminal conduct and the treatment and rehabilitation of offenders. Its primary aim is to describe the theoretical and empirical basis for clinical practice and research, but it also attempts to set psychological approaches in the context of criminology more generally. The first half of the book covers basic concepts in criminal justice and the study of crime, and examines the nature of offending from sociological, psychiatric, and psychological perspectives. The second half focuses on topics of particular concern to clinical practitioners.
