• I didn’t read the rest but that study looks st CT vs Exposure, which both fall within CBT.

    This is from another paper

    Most notably, exposure therapy (“exposure” or “exposure and response prevention”) is the key intervention strategy through which CBT improves outcomes for people with anxiety.

    I think that study echos who you have been saying, since it mentions that many CBT practioners may avoid exposure therapy and use less effective methods.
