Yesterday during my research methods class, I found this PhD thesis done by a student in U of New Orleans in 2015.

Glad to be able to see how to do conduct a research using grounded theory.

I need to do more findings on theories that are link to creative arts and play therapy.

1) Attachment theory - John Bowlby

2) Margaret Lowenfeld - use of NON-Verbal approach. 
The use of toys, sand (aka World Technique), mosaic (as part of the assessment during first assessment and last session).  
and use of SENSORIAL experiences -- Touch is essential
Proto-system thinking theory

3) Donal Winnicott-Object Relations Theory
