Yoo I’ve been all up in this thread recommending them. Last I checked they use REBT, which is a kind of precursor to CBT. I didn’t find it the most effective, but I joined a DBT skills group and am making my way through a year long program for that and have found it very helpful. I’m trying to address a lot more than substance abuse, though. Its considered more gold standard treatment for chronic suicidality or people struggling with borderline personality.
