Not all the skills in DBT will work for you. A number of these simply aren't for me, at least not right now. And that's okay. I went through the book while in residential treatment for depression, multiple outpatient programs, and most recently a certified/adherent DBT skills group.
The distress tolerance and emotional regulation units were especially helpful and I think everybody should know them regardless of their mental health status. I have yet to be completely sold on the mindfulness unit and as for interpersonal skills...well, they're great most of the time, but they rely somewhat on the person you're interacting with to act right lol.
But frankly the writing is awful. Sometimes I hit a couple sentences of truly the most patronizing, invalidating, belittling sentiment as far as patient-centric mental health material goes, and I'm shocked Marsha chose to word it that way. Most of the time it is cold and clinical. There are other small bits that simply need to be updated because they reference things like burning CDs, iPods, MP3s, and various skills don't take our modern lives into account.
If I had to hazard a guess I think when Marsha was writing and updating the materials, she absolutely hated the internet, social media, and video games. It comes through in her tone and in teaching different skills. But maybe I'm jumping to conclusions since she's a baby boomer and I'm a gen y/z cusper.
I really hope the book is updated soon. I don't know what's taking so long. For now, I think other books can probably do all this better but I was assigned this book for my DBT skills group and programs I did in the past.
