Reactive Attachment Disorder is a very serious condition because it indicates that a child has never formed secure attachments (during the firsy couple of years of life), and this prevents normal relationships from developing. Children who display RAD tend to be angry, hostile and mistrustful, keeping an emotional distance in relationships. They require a systematic program of behavior management and highly structured, routinized environments both at home and in school. The behavior management piece is straightforward. Take a look at Lynn Clark's book SOS Help for Parents and follow his guidelines (which are designed for use with children in general). You are in it 'for the long haul', as they say. It is commonly believed that children who display RAD will likely never achieve fully trusting, reciprocal relationships - they have been deprived of the necessary emotional underpinnings for such relationships because of inadequate early parenting.
