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-based therapy (children)
This is a parent education and psychotherapy intervention developed by Glen Cooper, Kent Hoffman, Robert Marvin, and Bert Powell designed to shift problematic or 'at risk' patterns of attachment – caregiving interactions to a more appropriate developmental pathway. It is stated that it is explicitly based on contemporary attachment and congruent developmental theories. Its core constructs are Ainsworth’s ideas of a Secure Base and a Haven of Safety (Ainsworth et al. 1978). The aim of the protocol is to present these ideas to the parents in a user-friendly, common-sense fashion that they can understand both cognitively and emotionally. This is done by a graphic representation of the child's needs and attachment system in circle form, summarising the child's needs and the safe haven provided by the caregiver. The protocol has so far been aimed at and tested on preschoolers up to the age of 4 years.
