Reactive
attachment disorder (RAD) is children establish unhealthy emotional connections
and struggle to manage their feelings. Children with symptoms of RAD could
always appear moody, fail to join social interactions to respond to comfort,
and are afraid and withdrawn. Disinhibited and inhibited are the main types of
RAD. However, according to Bowlby's theory and other studies, the main etiology
of RAD is childhood maltreatment, including physical, sexual, emotional, and
mental abuse, separation from their biological parents, or ESSENCE disorders of
children in their early stages of development.
