Emotion regulation skills should be mastered by early childhood, but many enter school with mild or serious deficits that may not be addressed effectively or early enough. This book presents in-depth background and practical information on the subject so school professionals can craft interventions that are developmentally appropriate, relevant, and timely. Written for practitioners, the book provides a unique combination of theory and background as well as guidance on application and evidence-based interventions that can be implemented immediately. Strategies are included for recognizing specific skill deficiencies or more general needs. The book provides solid support for school psychologists and other school-based mental health professionals. With targeted training at the classroom, home, and peer levels, children can achieve the vital skills they need for a lifetime of social interactions.
