Coping with Trauma-Related Dissociation: Skills Training for Patients and Therapists
by Boon, S., Steele, K., & van der Hart, O. (2011). New York: W. W. Norton & Company
This is a workbook that can be used by individuals who want to target specific trauma-related areas of their lives, as well as therapists who wish to use the exercises in their therapy sessions. Some of the topics include understanding dissociation, developing a sense of inner safety, learning how to regulate yourself, improving sleep, and coping with triggers.
The explanations in the book are short and easy to understand; however, if you're looking for more in-depth or scientific information, you'll have to look elsewhere. This book seems not to be written to impress a large amount of information on its readers; rather, it focuses on practical skills. In addition, short chapters are likely more easily digested for those who risk becoming overwhelmed by a lot of information.
Although the title is "Skills Training for Patients [...]", my impression is that high-functioning individuals may also find a useful exercise or two in this book, as most everyone has had one or another overwhelming experience or has a challenge in an area that is covered in this book. One doesn't have to have PTSD to experience loneliness, guilt, or fear as a challenge.
If you are in doubt as to whether or not this book is for you, have a look at the preview on Amazon. You can check out some of the exercises and worksheets to see if they appeal to you. https://www.amazon.com/Coping-Trauma-Related-Dissociation-Interpersonal-Neurobiology-dp-039370646X/dp/039370646X/ref=mt_paperback
Please be advised that it is strongly recommended that you work with a therapist, and not just do the exercises and worksheets on your own. A good place to start would be to ask your therapist if s/he recommends this kind of work for you or not.
