It is difficult to conduct research in psychotherapy, as the scientific method preferred by academic research is not neccessarily appropriate when it comes to assessing what happens in therapy. Art therapists and music therapists have traditionally worked side by side and both work in a predominantly non-verbal medium. As their respective professions grow to maturity, they have increasingly begun to develop their own research methods and tools.
