I have. I think you have to have a certain kind of behavioral patterns for it to be a good fit. When I was in DBT groups, I'd think, "What, do you guys think I'm ignorant or something? I know what all this is, I already do this stuff, it's common sense for me. You don't need to make me repeat this and give it a new name just to repeat it again"
The things they teach are.... really kinda average for a lot of folks. They're already subconscious habits for handling stressful situations (or I thought so for myself, at least). It seemed like some kinda marketing ploy or something, almost; like they had to make it some kinda fancy anagram in order to "sell it" or whatever. They took basic coping and grounding skills and stretched it out into this unnecessarily long and complicated process. I mean "ACCEPTS", "DEARMAN", "GIVE", "FAST", "IMPROVE ", "PLEASE MASTER", "MASTERy" ??? C'mon son, you know that's whack! I honestly think that DBT is for a select group people who need those skills broken down and rebuilt, not for those people who have the skills on a solid foundation and just need them strengthened. Idk, it might just be a shot in the dark here, but I think DBT is too widely used.
