Healing Attachment in Adults Through Integrative Attachment Therapy (IAT)

from Therapy on the Cutting Edge · host Institute for the Advancement of Psychotherapy

In this episode, I speak with Nigel about his work with Integrative Attachment Therapy (IAT). He discusses how his studies with Dan Siegel, M.D. and his meditation training in the Tibet Bon Dzongchen, led him to be very interested in what is a “mind”, how it works, what its about, and how ti develops. He discussed how attachment is the basis for the development of the mind, which we create "bottom up in our relation to others. He explained that the key developmental processes for the mind include attachment, care and nurturance, social rank, sexual identify and safety. He said that the novel part of the work that Daniel Brown, Ph.D., the coauthor of Attachment Disturbances in Adults: Treatment for Comprehensive Repair, was using an ideal parental figure to repair what had or had not been established in development. Nigel talks about the three pillars of IAT, where the therapist and client are collaborating on the work they’re doing together at the beginning of the session, doing the imaginal intervention of the ideal attachment figure, and then using metallization to process the experience and gain new awareness. He explained that they are helping a client to connect with the felt experience of feeling safe, seen, being able to trust and other elements of experiencing a secure attachment with this imagined parental figure. He shared that the conditions for a secure attachment include embodied trust, felt safety, being good enough, that its ok to explore, being able to down regulate the nervous system, and knowing your a good person. He spoke about how transference is encouraged to be shared directly with the therapist, and discussed using metallization, rather than using the therapist to provoke transference and letting it build up and then be worked through. We also discussed his work with psychedelics and its ability to help clients to integrate experiences in a different interpretive map. Nigel Denning, M.Psych, MA is a Counselling Psychologist and Director of Integrative Psychology and Medicine in Melbourne, Australia. Nigel is Research Fellow at Australian National University. Nigel has been involved in developing the Three Pillars of Attachment Repair and Integrative Attachment Therapy with David Elliott and Traill Dowie and developing the IAT Training Program.

Nigel is also clinical lead in several psychedelic medicine trials and a trainer in psychedelics and holotropic breathwork, having studied under Stanislav Grof. In addition, Nigel is a long-term meditation practitioner and teacher in the Tibet Bon Dzogchen tradition. Nigel has a profound understanding of how Eastern practices affect the mind and their subsequent connection to psychotherapy. Nigel is a jovial and kind person who is passionate about improving the world one mind at a time.
