Nearly 50 authors enlarge the empirical base of
psychodrama. The aim and research questions cover instruments, methods, and
social network as well as clinical investigations of children, youth and
adults. The last chapter deals with research on supervision, education and
training. The contributors used mostly quantitative and mixed-method and some
qualitative designs. This ends up in evaluated tools, quality development in
treatment, efficacy in supervision, effectiveness in education and training.
Some studies were exploratory others more rigorous and “gold standard”.

Half of the special issue is written in English or
German. Most of the authors come from Germany and Austria, but also from non
German speaking countries in Europe, Asia, Australia and America.
