Reactive attachment disorder
The broad theoretical framework for current versions of RAD is attachment theory, based on work conducted from the 1940s to the 1980s by John Bowlby, Mary Ainsworth and René Spitz. Attachment theory is a framework that employs psychological, ethological and evolutionary concepts to explain social behaviors typical of young children. Attachment theory focuses on the tendency of infants or children to "seek proximity" to a "particular attachment figure" (familiar caregiver), in situations of alarm or distress, behavior which appears to have survival value. This is known as a discriminatory or selective attachment. Subsequently, the child begins to use the caregiver as a base of security from which to explore the environment, returning periodically to the familiar person. Attachment is not the same as love and/or affection although they are often associated. Attachment and attachment behaviors tend to develop between the ages of six months and three years. Infants become attached to adults who are sensitive and responsive in social interactions with the infant, and who remain as consistent caregivers for some time. Caregiver responses lead to the development of patterns of attachment, that in turn lead to internal working models which will guide the individual's feelings, thoughts, and expectations in later relationships. For a diagnosis of reactive attachment disorder, the child's history and atypical social behavior must suggest the absence of formation of a discriminatory or selective attachment.
Attachment therapy
Attachment therapy is a controversial category of alternative child mental health interventions intended to treat attachment disorders. The term generally includes accompanying parenting techniques. Other names or particular techniques include "the Evergreen model", "holding time", "rage-reduction", "compression therapy", "rebirthing", "corrective attachment therapy" and Coercive Restraint Therapy. It is found primarily in the United States, and much of it is centered in about a dozen clinics in Evergreen, Colorado, where Foster Cline, one of the founders, established his clinic in the 1970s. This article describes this particular set of interventions although in clinical literature the term "attachment therapy" is sometimes used loosely to mean any intervention based on attachment theory, particularly outside the US. Attachment therapy as described in this article should not be confused with other schools of therapy which are more empirically based and which aim to address problems stemming from disrupted attachment to caregivers.
