What are the key similarities/differences between cbt and act? at times, one seems to suggest doing the opposite to the other. do they have similar short and long term success rates?

They are: very different concepts, thus the "inconsistencies" CBT is better known, studied , and possibly more successful in reducing certain kinds of pschological issues including addiction and OCD issues My Opinion only! Hope it's helpful Happy Healthy New Year Dr Z

Hare and tortoise: Like the hare and the tortoise, ACT is following the slow and steady path. We think traditional CBT hopped ahead into a lay theory of cognition -- which produced quick progress but long term problems. We'd rather take the slow, one step at a time approach of contextual behavioral science. Which one will go farthest? Let's see. Let's be patient and see.

Cognitions and Mindf: CBT is based on looking at looking to change your cognitions, to change your behaviours; ACT is Acceptance and Commitment therapy focuses on being mindful to the outside or your inner world to achieve an emotional balance Both are equally successful, but there is more scientific data for CBT.
