Back in my day, we called that Functional Analytic Psychotherapy. Oh god, are we on 4th wave CBT now?
Tomato, tomato...
I'm a fan of anything that moves away from "CBT for..." X, Y, or Z condition and focuses instead on the effective processes that cut across various treatment "packages." ACT is basically graded exposure and behavioral activation in a nice package. Beck's CT is cognitive restructuring and behavioral activation in a similarly nice package.
In practice, I often use a little bit of Beck-like cognitive restructuring (cough, cough... defusion) to help build tolerance (or "space") for difficult thoughts, feelings, and realities (e.g., grief, hopelessness, disability, chronic pain, anxiety, etc. -- acceptance, self-as-context). Unlike Beck, and to be a little pedantic, I'm really "restructuring" the relationship someone has with those thoughts, feelings, or realities as opposed to their actual content (which is why I'm able to include "realities," like disability, on that list). At the same time, I also focus heavily on self-monitoring (mindfulness) and values-based behavioral activation (values, committed action) with (not despite) those difficult thoughts, feelings, and realities.
If you squint... you can start to see a hexaflex. While what I described is essentially ACT, you can see how I'm also specifically utilizing different CBT "processes." You can also see that I didn't mention a specific diagnosis or patient population for whom I tend to utilize this approach. This model is very similar to many "traditional" CBT for "anxiety NOS" packages (e.g.,
CBT for panic,
CBT for chronic pain). My understanding is that Hayes did his postdoctoral training with Barlow, so this overlap is not by accident. Depending on patient need, I'll shift the degree to which I focus on the different processes described above (e.g., more exposure ["acceptance"] for someone with significant anxiety, more behavioral activation ["commitment"] for someone with depression, more tracking ["mindfulness"] for someone with significant cognitive dysfunction, etc.).
Having an idea of "active ingredients" (even if not totally born out in the science...
although behavioral activation for depression essentially has been) from different treatment packages is an important skill. Consistent with ACT, this expertise allows clinicians to
flexibly treat patients based on their needs and circumstances.
ETA: Not mentioned above but given that most patients I treat do have cognitive impairment, I often pull specific processes and strategies from
problem-solving therapy and "
CBT for ADHD," although I really wish the latter was called "CBT for executive dysfunction." I also casually incorporate some aspects of DBT in my work, too.
