It certainly is fine to post here as well as in other forums.

My bet is that there is a great deal of variation in the extent to which creative therapy programs incorporate CBT, ranging from "not at all" to "quite a bit".

In general, mainstream CBT hasn't focused much on using creative mediums to deliver CBT. I can't think of any reasons that one couldn't use art or music or movement as a way of delivering CBT. The question would be those methods are as effective and efficient as the usual approaches to delivering CBT (i.e. sitting and talking).

The best example of using creative activities to deliver CBT that I can think of is Susan Knell's book on using CBT with young children Cognitive-Behavioral Play Therapy.

Can anyone think of other examples?
