See Jason's comment above. Dr. Craig Childress has outlined the path to diagnosis. The APA just needs to listen. When a child doesn't want to see a normal range parent, treating them with a haughty, arrogant attitude, it's not because the target parent is abusive or negligent. Even severely physically abused children want to be with their parents. These children are acting this way to gain the approval of the alienating parent. The target is the path of least resistance... unconditional love. They don't even have to badmouth the target to accomplish this. It's a form of brainwashing. They erase any good feeling the child had for the target parent. Please look up Dr. Childress.
