Packed with practical tools, this manual presents DBT STEPS-E, a comprehensive social-emotional learning (SEL) program grounded in the proven skills of dialectical behavior therapy (DBT). Two complete curricula are designed to integrate seamlessly into multi-tiered systems of support in grades K-2 and 3-5 classrooms. With a focus on prevention, DBT STEPS-E offers a nonclinical application for building emotion regulation, coping, interpersonal, and decision-making skills aligned with core SEL competencies. Detailed lesson plans are accompanied by teaching scripts, examples, and "From the Field" vignettes. In a convenient large-size format, the volume includes a reproducible daily diary card to track skills use and 77 reproducible student handouts, which also can be downloaded and printed.See also the authors' curriculum for grades 6-12: DBT Skills in Schools: Skills Training for Emotional Problem Solving for Adolescents (DBT STEPS-A)This book is in The Guilford Practical Intervention in the Schools Series, edited by Sandra M.
