The controversy, as outlined in the 2006 American Professional Society on the Abuse of Children (APSAC) Task Force Report, has broadly centered around "holding therapy" and coercive, , or aversive procedures. These include deep tissue massage, aversive tickling, punishments related to food and water intake, enforced eye contact, requiring children to submit totally to adult control over all their needs, barring normal social relationships outside the primary caretaker, encouraging children to regress to infant status, reparenting, attachment parenting, or techniques designed to provoke cathartic emotional discharge. Variants of these treatments have carried various labels that change frequently. They may be known as "rebirthing therapy", "compression therapy", "corrective attachment therapy", "the Evergreen model", "holding time", "rage-reduction therapy" or "prolonged parent-child embrace therapy". Some authors critical of this therapeutic approach have used the term Coercive Restraint Therapy. It is this form of treatment for attachment difficulties or disorders which is popularly known as "attachment therapy". Advocates for Children in Therapy, a group that campaigns against attachment therapy, give a list of therapies they state are attachment therapy by another name. They also provide a list of additional therapies used by attachment therapists which they consider to be unvalidated.
