EQUIP is a new and effective program that motivates and equips them with social skills young people with antisocial behavior problems need to help themselves and one another. This book provides all the material needed for understanding and implementing the EQUIP program. The first chapter develops the rationale for EQUIP, introduces its basic features and components, and describes a recent study of its effectiveness. The rest of Part 1 concerns the techniques (Chapter 2) and the skills (Chapters 3 through 5) needed for motivating antisocial youth and equipping them with skills for peer help. The chapters in Part 2 address program-level considerations, including procedures for program implementation and maintenance (Chapter 6), principles for developing a positive staff culture (Chapter 7), and ways in which EQUIP might be adapted or expanded (Chapter 8). Two appendixes contain two of the assessment instruments mentioned throughout the book. (Contains 14 figures, 12 tables, and 254 references.) (SLD)
