 The following research suggests that there are four main factors that create therapeutic change:

1 The client and the content ie what you bring in terms of the situation and your openness to consider change.
2 The therapeutic relationship ie the trust built up between client and therapist.
The above forms the larger extent of therapeutic change and the following factors below are significant but less so:
3 Hope ie can this be held by the therapist and eventually the client 
4 The type of therapy model  and the techniques used.
