You have got a discussion going on art therapy anyway whereas I ended up writing one on sex, drugs, rock,'n,'roll etc. yesterday and so far no one is interested in the latter.
I would say that art therapy can be done from various perspectives. I would say it is a recognised profession and there have been individuals who have called themselves art therapists who have been stopped from practicing for this reason. In England there is a requirement to be registered with The British Association of Art Therapy. I began the journey to train which takes 2 to 3 years but unfortunately did not complete it. This training involves academic studies, clinical placement and undertaking personal therapy.
Having begun the journey to become an art therapist but not completeId it I would say that I remain interested in the field but an amateur nevertheless. In this respect, I have run creative art groups and have found that some individuals can participate for relaxation and making art. However, I would say that talking is often a part of this.
There is a whole body of research on art therapy.
Much is based on the whole tradition of psychotherapy, extending back to the thought of Freud, dare I say it, along with Melanie Klein. However, that does not mean that there are no other approaches because there are, including the person centred.
In England the professor is one which is used in schools and psychiatry hospitals, but in some other settings, such as hospices. However, it often receives less funding than therapies which are considered more cost effective, such as cognitive behavioral therapy.
On the level of healing, based on my own engagement, I found that the art making had some but not completely value. In some senses, I found that translating experience into images was helpful. The downside for me was that I took an interest in the art therapy because I was serious about making art and the need to produce 'good' quality art got in the way. I am not sure that the tension between therapy and making quality art has to exist
Since studying art I find that I am too inclined to
wish to analyse my art and this sometimes interferes with my creativity when I am making it, so subjectively I am not one hundred per cent a fan of it.
What I have found is that creative writing, especially fiction seems to have more of a transformative role for me, and I do not feel that the tension is so great between expression of emotions and writing well. Perhaps that goes back to what I said in the thread about Sigmund Freud, and of course it is my own subjective experience.
