Good point. I like Hayes' idea that we need to help clients change their relationship to their dysfunctional thoughts and I agree that this has been implicit in Beckian CT. Perhaps if we look at it more explicitly we'll find more effective ways to doing this.

However, my understanding is that Hayes argues emphatically that we should not try to challenge the content of dysfunctional cognitions, just focus on changing their relationship to the cognitions. I must admit that I don't quite understand his reasoning on this point. Does anyony understand why he's convinced that we shouldn't try to change dysfunctional cognitions?
