Teaching prosocial behavioral alternatives at an early age may enhance a child's personal development and help prevent more serious difficulties in later childhood, adolescence, and early adulthood. This book provides classroom teachers and others working with young children with a guiding strategy and concrete techniques for instruction in prosocial skills. The skillstreaming method systematically teaches behaviors necessary for effective social interactions. Sample reports, checklists, handouts, and forms are included. Following an introduction that provides a rational for teaching prosocial skills and discusses who benefits from skillstreaming, the chapters of the book are: (1) "Components of Skillstreaming," focusing on modeling, role playing, performance feedback, and transfer training; (2) "Identifying and Evaluating Children for Skillstreaming," including assessment methods, peer nomination, roster rating scales, naturalistic rating scales, analogue observation, behavior rating scales, and self-reports; (3) "Planning and Beginning Skillstreaming Instruction"; (4) "Implementing Skillstreaming Instruction," including enhancing motivation, identifying situations, and presenting behavioral steps; (5) "Prosocial Skills," presenting the skillstreaming curriculum, a set of 40 skills divided into six skill groups; and (6) "Managing Behavior Problems," describing a six-step management plan with techniques for dealing with problematic behaviors. Contains 148 references. (BGC)
