Multiplicity: Dissociative Identity Disorder - A Clinicians Guide
coming soon
A thoughtful, practice-informed space to build clarity, confidence, and ethical competence when working with dissociative identities.
The Multiplicity course is being developed as a companion to the Multiplicity eBook, designed for clinicians who want more than theory — and are looking for practical, affirming guidance when working with dissociative identities.
This course will expand on the foundations introduced in the eBook, offering structured learning, clinical reflection, and applied examples drawn from real-world practice.
​
At this stage, the course is in development.​
What You’ll Get:
While details are still being shaped, this course is intended to support clinicians to:
Build confidence working with clients who experience dissociative identities
develop steadier clinical footing when navigating uncertainty, complexity, and internal system dynamics.
​
Move beyond diagnostic curiosity into ethical, relational practice
shift the focus from labels toward attuned, respectful engagement that centres safety and collaboration.
​
Understand common clinical dilemmas, ruptures, and missteps
explore challenges that often arise in this work and how to respond with reflection rather than reactivity.
​
Apply dissociation-affirming principles in day-to-day therapy
translate core concepts into practical language, pacing, and therapeutic decisions within sessions.
​
Reflect on power, language, and safety in this work
consider how therapist positioning, words, and assumptions can impact trust, autonomy, and care.
This course may be a good fit if you are…​
-
A psychologist, therapist, or mental health clinician
-
Already working with — or expecting to work with — clients who experience dissociative identities
-
Wanting support that goes beyond surface-level education
-
Seeking guidance that is trauma-informed, dissociation-affirming, and ethically grounded
How this fits with the Multiplicity eBook
The Multiplicity course has been developed alongside the Multiplicity eBook and is intended to sit with it as part of a broader learning offering.
​
The eBook will be included as part of course enrolment, providing a shared foundation for the material explored in the course.
​
The course itself is designed to build on those foundations through structured learning, reflection, and facilitated discussion.
