Agreed with the above. I personally don't have a huge problem with further specialized training and credentialing, although it'd be nice to first show that doing so improves care/outcomes (or something similar) relative to the alternative. The VA is strongly pushing the use of EBTs and associated templates (e.g., for CBT, PE, CPT), and there's been pushback from some of the psychologists with whom I work (particularly those who've been practicing a while). Their points are typically similar to those mentioned by smalltownpsych--that essentially all appropriately-trained practicing psychologists should be able to do these things, and have likely been using elements of the various modalities in their treatments for years. However, I do think it's important to differentiate, say, "CBT- and ACT-informed ecclectic therapy" (my own terminology) from stringent existing protocols (e.g., CBT-i, cognitive therapy for chronic pain, etc.).
I agree that all competently-trained psychologists should be able to provide many of these EBTs in their areas of competence and will likely have some exposure to various others, and that psychologists shouldn't be using (or claiming to use) EBT elements in which they aren't formally trained. Unfortunately, that just doesn't seem to be how things always work. And there's really no formal way yet available to many folks to determine if you actually are competent in something. A psychologist could pick up a book on ACT, read through it, and feel that they're doing a solid job of applying it, but may be providing a very different intervention than folks who've also gone through ACT workshops, had their sessions reviewed, and the like.
