This work looks at what interventions work in assessing and treating substance-abusing criminal offenders. It covers approaches to treating offenders, including women, juveniles, and those with the dual diagnoses of substance abuse and a mental disorder. From assessment and diagnosis through individual, family, and group interventions and monitoring probationers, this work should be a useful resource for psychologists, psychiatrists, social workers, criminologists, sociologists, correctional officers, and other working in community-based and institutional settings.
