Updated and revised, this edition offers an introduction to clinical work with this difficult-to-treat population. Providing a synthesis of chemical dependency and mental health models, the book articulates a framework for assessment and treatment and describes a range of effective counselling and motivational strategies for adolescents and adults. The book includes discussions of developments in treatment, sample treatment plans, increased coverage of ways to incorporate 12-step concepts into mental health interventions, and a section on trauma-based disorders in addicted female adolescents.
