This leading professional resource and course text is now in a substantially revised fourth edition, with 75% new material reflecting 15 years of advances in practice and policy. Expert contributors provide an overview of assessment and intervention with clients with substance use disorders (SUD) and describe evidence-based treatment modalities. Specific populations are addressed, including adolescents, older adults, women, sexual and gender minority clients, people with co-occurring mental health challenges and/or behavioral addictions, and system-impacted clients. The book explains current models of SUD service delivery and identifies emerging issues facing the field. Throughout the chapters, case examples illustrate the techniques discussed.
