This article presents a perspective on addiction that not only substantiates why group therapy is the treatment of choice for addiction, but also integrates diverse perspectives from 12-step abstinence-based models, self psychology, and attachment theory into a complementary integrative formula. Attachment theory, self psychology, and affect regulation theory characterize addiction as an attachment disorder induced by a person's misguided attempt at self-repair because of deficits in psychic structure. Vulnerability of the self is the consequence of developmental failures and early environmental deprivation leading to ineffective attachment styles. Substance abuse, as a reparative attempt, only exacerbates that condition because of physical dependence and further deterioration of existing physiological and psychological structures. Prolonged stress on existing structures leads to exaggerated difficulty in the regulation of affect, which leads to inadequate modulation of appropriate behavior and self-care and increased character pathology.

This article selectively highlights relevant areas of neuroscience research which have direct application for attachment theory and group psychotherapy. Emerging evidence from the neurosciences is revealing that the developing brain of the infant, sculpted by the earliest attachment relationships, continues to be malleable in adulthood and can be profoundly influenced by ongoing relationships throughout one's lifespan. Advances in the neurosciences are also supporting the idea that strong attachment bonds and external interpersonal interactions that arise within the context of these attachments are registered as a person's neurophysiology and neurobiology. Attachment theory in particular provides a common language and conceptual framework from which the contributions from the neurosciences can be made applicable to group psychotherapy.
