Concerning how widespread DBT is: In the last five years in grad school, I knew many people doing a psychology PhD and DBT was one of the major training focuses for their clinical psychology curriculum. I would say the characterization given by this article matches very closely with what they told me over the last ~5 years.
My impression of DBT compared to CBT, based on what my friends told me, is that DBT is much more confrontational. I remember one friend even specifically said that it took her a long time to "unlearn" the therapist's natural response to affirm and validate, but then redirect negative feelings with skills.
