Hi Lorraine,
I recommend looking at Pat Wilcox's blog. You will find many relevant blog posts there on this and many other topics related to Trauma-Informed Care and treatment of youth in residential, foster care, and child welfare. Go to www.traumaticstressinstitute.org and click on her blog. She also has a book called Trauma Informed Care: The Restorative Approach published by NEARI press that would be very relevant.
