6. Hypnosis and CBT with depression and anxiety., By German, Ester
Australian Journal of Clinical & Experimental Hypnosis. 32(1), May 2004, 71-85.

Also, there are a zillion books, depending on your take of CBT most hypnosis books may apply. I think most of mine apply eg, The Answer Within. But it depends on how narrow or broad you definition of CBT happens to be. (For instance, if you have to replicate A. Ellis, to be called CBT, then non-apply.)
