Numerous group interventions have been shown to be effective for helping K-8 students who are struggling with--or at risk for--a wide range of mental health and behavior problems. This unique book gives school practitioners indispensable tools for making any evidence-based group intervention more successful. It addresses the real-world implementation challenges that many manuals overlook, such as how to engage children and parents and sustain their participation, manage behavior in groups, and troubleshoot crisis situations. In a convenient large-size format, the book includes case examples, reflection questions, role-play scenarios, and 31 reproducible forms and handouts; the print book has a large-size format for easy photocopying. Purchasers get access to a Web page where they can download and print the reproducible materials. This book is in The Guilford Practical Intervention in the Schools Series, edited by Sandra M. Chafouleas.
