One of the most respected and widely used autism interventions, Pivotal Response Treatment uses natural learning opportunities to modify key behaviors in children--leading to widespread positive effects on communication, behavior, and social skills. Now the pioneering experts behind PRT have created a comprehensive modern guide to this research-based approach, completely reworked and revised for today's therapists, educators, and parents. Strengthened with new research and more step-by-step guidance, this bestselling PRT guidebook is now reorganized to support children on their whole developmental trajectory, from infancy through adulthood. New and revised chapters cover critical topics--including assessment, self-management, and life beyond the classroom--and the book's down-to-earth, accessible style ensures that all readers can grasp PRT principles and apply them effectively. With this proven approach backed by more than 25 years of research, professionals and families will support children with autism as they enjoy more positive interactions, more effective communication, and higher academic achievement. Use the proven PrRT approach to: (1) advance children's communication and language skills, even in extremely challenging cases; (2) aid early identification and intervention; (3) improve children's motivation and performance in school; (4) foster friendships with peers during play dates and other social interactions; (5) increase positive behavior by combining functional assessment and self-management strategies; (6) decrease disruptive behavior; and (7) help young adults make a smooth transition to college, career, and community life.
