In a convenient large-size format, this friendly workbook gives Skills System participants a wealth of tools for learning how to manage feelings, navigate the ups and downs of life, and reach goals. Designed for learners of all ages and abilities, the volume includes nearly 200 reproducible handouts and worksheets, though not all of them are used in every skills program. The Skills System is grounded in dialectical behavior therapy (DBT), a proven approach that has helped millions of people around the world cope with complex mental health difficulties and build a life worth living. Worked examples show how to fill out the worksheets for adults; the companion website provides worked examples for elementary and high-school age youth.
