Attachment-based therapy (children)
Attachment-based therapy applies to interventions or approaches based on attachment theory, originated by John Bowlby. These range from individual therapeutic approaches to public health programs to interventions specifically designed for foster carers. Although attachment theory has become a major scientific theory of socioemotional development with one of the broadest, deepest research lines in modern psychology, attachment theory has, until recently, been less clinically applied than theories with far less empirical support. This may be partly due to lack of attention paid to clinical application by Bowlby himself and partly due to broader meanings of the word 'attachment' used amongst practitioners. It may also be partly due to the mistaken association of attachment theory with the pseudo-scientific interventions misleadingly known as attachment therapy. The approaches set out below are examples of recent clinical applications of attachment theory by mainstream attachment theorists and clinicians and are aimed at infants or children who have developed or are at risk of developing less desirable, insecure attachment styles or an attachment disorder.
Marc David Lewis
Through a sabbatical at the University of Oregon in 2000-2001, Lewis took the next step in developing his integrated model by delving into the neural underpinnings of emotion regulation. His current research program tests this model by examining brain and behavior in normal and clinically referred children and assessing neural changes corresponding with successful treatment. His papers on the contribution of dynamic systems theory and affective neuroscience to understanding human development and clinical syndromes have appeared in journals such as "Child Development", "Behavioral and Brain Sciences", "Development and Psychopathology", and "Perspectives on Psychological Science". He has also co-authored two books with his wife, Dr. Isabela Granic. The first is an edited volume of dynamic systems approaches to emotional development. The second is a guide for parents about when to attempt sleep training with toddlers. 
Dr. Lewis' most recent book, "Memoirs of an Addicted Brain", is an account of his addiction to drugs as a young man with accompanying explanations of the neurobiological processes underlying various drug experiences as well as the process of addiction itself.
