What is “Dissociative Identity Disorder” and how does it relate to trauma?

Dissociative Identity Disorder (“DID”) is a mental health disorder in which an individual's experience of self becomes fragmented, and “self-states” become split off or separated from consciousness.

Dissociation takes many forms, such as depersonalization and derealization, and serves as a reaction to developmental trauma when an individual is faced with repeated betrayal such as abuse or neglect from those in a position of trust. This “biological paradox” gives rise to conflictual emotions and the drive of going both toward and away from the same attachment figure resulting in irresolvable fear and a fragmentation of the mind.

From the Interpersonal Neurobiology (IPNB) perspective, such traumatic relational experiences disrupt the capacity for integration, moving individuals outside an array of context-specific windows of tolerance for a range of emotions, making them prone to chaos and rigidity, and isolating “self-states” in DID as separated fragments of a whole waiting for the healing process of integration to bring them back to an experience of wholeness.

In this course, you will receive a never before seen interview with Dr. Dan Siegel's former client who was diagnosed and healed with Dissociative Identity Disorder and has gone on to study psychology and practice psychotherapy for the last 20 years.

Whether you are a therapist or a clinician, you may have noticed that some mental health disorders receive a lot of attention, while others are rarely discussed in professional and academic environments. With lack of attention and formal training, conceptualization and treatment of less discussed mental disorders can become a challenge. This course brings you the rare opportunity to observe and learn from a real life client's experience of Dissociative Identity Disorder (“DID”) as an illustration of the impact and treatment of disorganized attachment and dissociation.

Why should you consider taking this course on Treating Disorganized Attachment and Dissociation?

Through the integrative experience of an attuned relationship between the therapist and client, deep processing of traumatic material is made possible through the presence, attunement, resonance, and trust within the therapeutic relationship. This relationship allows the client to integrate psychological material, creating coherence between self-states, and enabling an integrative individual to access a wide array of memories and emotions with widened windows of tolerance and more adaptive responses to challenge within the person as a whole.

Although there are many different therapeutic techniques to address and treat trauma, IPNB's focus on integration as the basis of well-being illuminates how DID is an outcome of the excessive isolation of different “self states” revealing excessive differentiation and impaired linkage. Through the treatment of the individual as a whole and the attunement to individual self-states, the clinician is able to understand and facilitate the linkage of the function of each individual dissociated facet of the person, processing the psychological material that is held in isolation within each separated state and then facilitating the integration—the linkage of differentiated states—of the individual as a whole person.

With so many different therapeutic orientations to work with trauma, what makes this approach useful for treating Dissociative Identity Disorder?

Course Details

In this course you will have the opportunity to become immersed in a one-of-a-kind interview with Dr. Dan Siegel's former client who was diagnosed with DID and worked through the trauma and dissociative barriers to heal the condition through therapy. She has gone on to practice psychotherapy for the last 20 years. DID is a mental health condition in which an individual's experience of self becomes fragmented, and “self-states” become separated from one another, interrupting the continuity of consciousness. In this course, you will learn how to work with differentiated self-states by processing implicit traumatic memories, treating attachment patterns that are disorganized, and catalyzing relational trust and healing to create lasting change and the experience of an open, coherent autobiographical narrative, wider windows of tolerance, an access to the “open plane of possibility” with the Wheel of Awareness practice, and the deeply transformative experience of living with wholeness.

This course will enable you to learn the specific assessment and treatment strategies to effectively care for those with DID. Understanding DID also affords us the chance to gain insights into dissociation as a response to disorganized attachment relationships while also learning about the developmental and neurobiological nature of attachment, clinical conceptualization of working with dissociation, and treatment approaches to healing the post-traumatic sequelae of developmental trauma.

IPNB is not a “form of therapy” but rather a deep understanding of the mind and mental health that informs all forms of therapy, and in this course we will focus on the integration of differentiated, fragmented self-states of DID. Through the relational connection established therapeutically with each of the self-states, the clinician is able to observe and understand the function of each individual part, find a bridge across states through open awareness cultivated in integrative practices in session and at home, and then process the psychological experiences and adaptive role that is protected within each segmented state. This relational connection also allows the client to integrate previously fragmented forms of memory and emotion, creating coherence across self-states, and dismantling the previously necessary dissociative barriers to liberate a new way of living with fluidity, integration, and wholeness.

Here are some highlights of what you will learn:

  • Clinical conceptualization and strategy to work with individuals with Dissociative Identity Disorder
  • Understanding how attachment patterns impact neuroscience and brain development
  • Disorganized Attachment: What it is and what it isn't
  • Understanding the role of attachment patterns and the capacity for integration
  • Dissociation as a consequence of disorganized attachment
  • Dissociative Identity Disorder from a Clinical Point of View
  • 5-Phase step by step guide to treating Dissociative Identity Disorder
  • Treatment Implementation and Assessment
  • How dissociative barriers shift and how to work with meaning and emotion
  • How windows of tolerance widen with therapy
Plus, as a member of this cohort you can join Dr. Dan Siegel for two live Q&A calls!

Testimonial by Dr. Siegel's Client

Student Testimonials

"I was very impressed with the information that was provided in the course, [Understanding and Treating Disorganized Attachment and Dissociation]. I believe the firsthand account of someone who has lived with DID and is now a clinician herself was fundamental in helping me understand how to work with this presentation. I found the live Q and A session[s] especially helpful. Thank you for providing this training opportunity. I look forward to taking other Mindsight courses."

"It is rare to find a training resource that takes professionals deep into the true complexities of Interpersonal Neurobiology. Dan Siegel's course, Understanding and Treating Disorganized Attachment and Dissociation – A 2 Month Online Intensive, was of extremely high quality: well structured, professionally challenging, and designed to develop excellent, clinically informed practice. It is extremely forward thinking to recognise that a range of professions encounter complex trauma and need to respond with clinical and relational excellence. Thanks to [Dr. Siegel's] intense, well-resourced course, I have up-to-date knowledge regarding survival strategies in victims. Continuous access to the [online] platform means this is a learning experience well worth investing in."
