Once again I am struck by the similarities between our theories. The work you describe is very compatible with how a CM therapist would work. We believe that a patient changes her pathogenic belief in many ways through insight, real life experiences, and identification with the therapist. The process of testing enables the patient to re-enact her fears or trauma in the transference with the therapist. This gives her the possibility of discovering that her fears are untrue or at least over generalized. The summary of CM will provide more details on the specific techniques of testing that I am talking about.
A consistent difference our theories seems to be that we believe that our patients aren't always able to verbalize their pathogenic beliefs. We often infer them from how the patient acts with us and what feelings are generated in us. There are times when one would talk about and point out what is going on between the patient and the therapist and others when the act of passing the test- not retraumatizing the patient is sufficient.
