My eldest son has experienced similar symptoms to RAD, and what I can say, is that they have trouble socializing with others. Although group therapy is beneficial for them, it is sometimes troublesome getting them to go. My son has slowly become his own man, and I have seen fewer and fewer problems with him. He is now 22 and acts as if he just turned 16. They need to be forced into a social environment. Sports activities, Art classes, or anything that they might be interested in, that is consists of interacting with others. They need chores, no matter how much they object. I find that putting chores on a list and hanging it somewhere where they can choose and initial when they are finished, is a great start. You can also, put the chores on little pieces of paper and put them into a bowl or chest, and have each child and parent draw one out until they are all distributed. Then the group can trade chores until everyone is happy. This also helps with socializing the children. Also, taking the time to sit and talk as a family is very beneficial. Communication is the key to success and socialization! Have everyone sit quietly, while only one person talks, usually holding a stick or some other object. When another person wants to talk, they hold out their hand for the object, It then gets passed to that person. This teaches the children to listen and be patient when someone is talking. It also gives them the confidence to speak their mind when it is their turn to hold the stick. And confidence is the greatest attribute that a child can have.
