Look into TBRI (Trust Based Relational Intervention). It was developed by Karyn Purvis out of Texas Christian University. It's a set of practical applications to working with Foster youth. The primary goal is to help build trust as the Foster program can be great at taking away a kids ability to trust anyone. I've heard they are great at answering emails etc so you could ask about it's application with an individual with autism. https://child.tcu.edu/about-us...sthash.7QtMBWz0.dpbs
