Sandplay is effective with both adults and children. Some sandplay therapists prefer to work mainly with children, some prefer to work mainly with adults.
‘Sandplay’ is from the German world ‘sandspiel’ coined by Dora Kalff, the founder of the therapeutic method known in English as Sandplay Therapy.
The term is sometimes used to broadly and imprecisely to describe therapy which is more accurately called Expressive Therapies or Sandtray work. Sandplay Therapy refers precisely to the depth psychological method of Dora Kalff, including training elements she considered essential to her method.
