This workbook has the potential to be life-changing for many people. I read through the workbook hoping to be able to recommend it to some of the teens that I work with. However, I feel strongly that this book is likely more appropriate for adults than for teens. I was uncomfortable with some of the assumptions that the book puts forth about the functions of the behaviours, the nature of the trauma (e.g., I foresee some of the teens I work with minimizing their trauma when held next to some of the examples in the book), and caregivers (e.g., there is a general theme within the book that parents are a source of trauma rather than a resource to cope with trauma, though I suspect this is unintentional--this is not the message I want to send to my client's parents). That said, the theory underlying this approach and the exercises themselves are very applicable and useful for the teens I work with. All-in-all, while there is excellent material within this workbook, I will need to be very thoughtful about which clients I might recommend it for, or which pieces of the workbook to work through with them.
