I ought not to be the right person in answering this question as I am just a new comer to Ericksonian Therapy. Some well-known followers are famous for their ability to utilize their own approach with the Ericksonian therapy, it is a different from simply eclectic. Read the work of Rossi, you will find how Jung talk with Erickson(though it is difficult to me), Yapko beautifully utilize the stregth of CBT in his work too. However, I personally find the change focus of Ericksonian Therapy are better fit with theory that also promote a change, you can find Erickson do desensitization in his work, rather than explaination of the past.
