Redecision therapy is an adversarial form of psychotherapy. It rests on the assumption that different parts of the personality (ego states) can battle it out for executive control of the personality.
Much of the work in redecision therapy is battling against and seeking to reject the Parent part of the personality. Or the part that seeks to restrict the Free Child aspects of us resulting in neurosis of some kind such as anxiety or depression. The parent part usually comes from our early lives and can involve at times quite vitriolic and caustic messages delivered in quite harmful way such as with the use of shame, physical assault and so on.
We all dislike aspects of self. Stop disliking it and start liking it.
This as we know can be quite effective and people can feel significant difference in a reasonably short space of time. However it has in it an inherent contradiction. In empty chair work one is often speaking with this parent part and rejecting of it. However as we know the chair is empty. There is no one in it, or should I say, what is in it, is a projected part of self. Part of me is in the empty chair. Thus I am in fact rejecting a part of myself which is counter therapeutic.
At some point one needs to switch from rejecting this part of self to an integration of it. Instead of battling against it one seeks to love or accept this part of self. Accept that I have a caustic, vitriolic part of me and to accept it as part of me. This can be quite interesting work to watch. One switches from an adversarial approach to an assimilative approach to psychotherapy.
