Who is ACT not suitable for?

Acceptance and commitment therapy is not the right first choice for someone in acute crisis who needs concrete problem-solving, for someone using "acceptance" to stay passive in a dangerous situation, or for conditions with a faster, better-evidenced protocol such as panic, phobias and OCD, where exposure-based CBT comes first.
Who ACT suits
People who have tried to control or get rid of difficult feelings and found the effort has taken over their life. Often these are highly intelligent, over-intellectualising clients caught in mental loops, for whom arguing with a thought has become its own problem. ACT changes the relationship to the thought rather than the thought.
Who it is wrong for
Someone in a severe, acute crisis needs stabilisation and concrete problem-solving, not values work. And acceptance is sometimes misused as a reason to stay put: if a situation is dangerous or needs changing, accepting it is the wrong move. We watch for that.

What are the disadvantages of ACT therapy?
Its language can feel abstract, and some people find the exercises odd. It is slower than exposure for problems where exposure is the answer, which is why we do not use it as the first treatment for panic, specific phobias or OCD. And it can be delivered as a philosophy rather than a therapy; at The Lyceum it is woven into CBT and measured like everything else.
Where we use it most
Chronic pain, health anxiety, burnout and life transitions, where struggling with the feeling has become the problem, and wherever cognitive restructuring has turned into a mental compulsion.
How we decide at assessment
We ask two questions. Is there a clear maintaining cycle with a well-evidenced exposure treatment? If so, that comes first. Has the fight with the feeling itself become the problem, so that every attempt to control it makes life smaller? If so, ACT is the right frame, usually woven into CBT rather than replacing it, and measured like any other course.
