This document discusses a study on applying the intensive interaction approach to help adults with severe intellectual disabilities and autism spectrum disorder. It describes how the approach aims to develop communication abilities, establish genuine connections, and enhance social engagement. The study shares stories of two individuals, Cindy and Fai, who initially avoided interaction and had limited communication, but through building trusting relationships and engaging them in activities, they started to smile, make eye contact, and join group activities. The document emphasizes that intensive interaction is a slow process that requires patience and being genuine to see changes.
