This widely used reference and text captures the breadth of current knowledge about substance abuse and its treatment. Noted theoreticians and practitioners provide an authoritative introduction to the six most prominent psychosocial treatment approaches. For each approach, a chapter on basic assumptions and theories is followed by a clinical chapter that describes specific therapist actions and strategies and offers a start-to-finish view of treatment. In addition, a single chapter discusses psychopharmacological interventions. Comprehensive, clear, and accessible, the text concludes by discussing ways to integrate elements of multiple approaches into carefully planned work with individual clients.
