Recognized as one of the most effective coaching programs for parents of young children (up to age 6) with autism spectrum disorder (ASD) and related social communication delays, this two-book set has been fully revised and updated. It presents everything needed to implement Project ImPACT, an intervention curriculum that teaches parents ways to enhance children's social engagement, communication, imitation, and play skills, within meaningful activities and daily routines. The Guide to Coaching Parents provides a complete introduction and step-by-step coaching procedures for practitioners working with individual parents or groups. The Manual for Parents, which includes 20 reproducible forms, helps parents master the strategies and use them at home. Both volumes have a convenient large-size format. The parent manual is also sold separately (ISBN 978-1-4625-3808-9). Companion Websites Purchasers get access to a companion website featuring 42 reproducible forms for practitioners and parents (several of which can be filled in onscreen before printing), as well as video clips of the techniques and PowerPoint slides for use in teaching parent groups. A second companion website for parents features the parent forms and video clips only.
