Focusing on how to conduct and lead groups in a variety of therapeutic settings, this book covers theory, process, leadership, techniques, ethics, special populations, and challenges as they relate to group work in a positive, realistic, and knowledgeable way. The authors introduce important conceptual and practical information and then use activities, exercises, field study assignments, and personal application questions to help students apply concepts to their work and lives. The fully updated Third Edition brings concepts to life through "student voices" in every chapter, examples drawn from the authors' over 25 years of experience, and demonstration video content that contains scripted sessions corresponding with every chapter.
