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)
Developed by Daniel Schechter and colleagues. They developed an experimental paradigm informed by attachment theory called the Clinician Assisted Videofeedback Exposure Sessions to test whether traumatized mothers, who often suffered psychological sequalae from a history of abuse and violence, could "change their mind" about their young children. The technique used was to watch video-excerpts of play, separation and similarly stressful moments in the presence of a clinician who asks the mother to think about what she (and her child) might be thinking and feeling at the time of the excerpt and at the moment of videofeedback. It applies the principles of mentalization as an aide to emotional regulation with these traumatized parents. It also involves elements of prolonged exposure treatment, the video-based treatment Interaction Guidance, and psychodynamically-oriented child–parent psychotherapy. Schechter and colleagues showed a significant change in the way mothers perceived their own child and their relationship together.
