Attachment and Health
John Bowlby and Mary Ainsworth developed attachment theory in the 1960s while investigating the effects of maternal separation on infant development. The development of the Strange Situation task in 1965 by Ainsworth and Wittig allowed researchers to systematically investigate the attachment system operating between children and their parents. The Strange Situation involves separating infant-parent dyads and observing infant behaviours upon reunion. Infant behaviour tended to follow patterns, leading to the development of three attachment categories: Secure, Anxious-Avoidant, and Anxious-Resistant. In 1990, Ainsworth added a new category, championed by Mary Main, called Disorganized/Disoriented attachment, characterized by its less reliable pattern of behaviour.
Attachment therapy
In 2001, 2003 and 2006, ATTACh, an organization set up by Foster Cline and associates, issued a series of statements in which they progressively changed their stance on coercive practices. In 2001, after the death of Candace Newmaker they stated "The child will never be restrained or have pressure put on them in such a manner that would interfere with their basic life functions such as breathing, circulation, temperature, etc." A White Paper, formally accepted in April 2007, "unequivocally state(s) our opposition to the use of coercive practices in therapy and parenting." They acknowledge ATTACh's historical links with catharsis, provocation of rage, and intense confrontation, among other overtly coercive techniques (and indeed continue to offer for sale books by controversial proponents) but state that the organization has evolved significantly away from earlier positions. They state that their recent evolution is due to a number of factors including tragic events resulting from such techniques, an influx of members practicing other techniques such as attunement and a "fundamental shift ... away from viewing these children as driven by a conscious need for control toward an understanding that their often controlling and aggressive behaviors are automatic, learned defensive responses to profoundly overwhelming experiences of fear and terror." While being of the view that authoritative practices are necessary, and that nurturing touch and treatment aimed at the perceived developmental rather than chronological age are an integral part of the therapy, the White Paper promotes the techniques of attunement, sensitivity and regulation and deprecates coercive practices such as enforced holding or enforced eye contact.
