Structural Family Therapy
Using a toy for each member, even when they are all present, helps to distance the family from their difficulties. Distance from the problem is what all art and creativity provide. Creating an image or structure outside of the thoughts bouncing around in the brain is the most useful purpose creative therapy can serve. Space gives the family a different perspective and a better chance of finding a solution within themselves.
This is mostly used as an assessment for the therapist to understand the family dynamics more fully. However, it can be used to with older clients and parents to build insight into the current family dynamics. It can also be used as a goal setting activity when discussing what the family desires from treatment. Have the family arrange the toys how they would like them to be.
