This training captures the ‘sweet spot’ between ACT, IFS and TIR, tailored to a wide range of psychedelic therapy challenges (See Spectrum of Selves paper: https://www.frontiersin.org/articles/10.3389/fpsyt.2021.727572/full for a detailed breakdown of these). Based on high-density data collected from over 50 participants attending our retreats, this training highlights what we know has been helpful in a psychedelic context. It integrates Internal Family Systems and Traumatic Incident Reduction (a titrated and structured imaginal exposure approach) with Acceptance and Commitment Therapy (ACT) into a simple and ACT-consistent framework. ACT provides the overarching framework of evolutionary and behavioural science principles. TIR and IFS offer additional engineered applications so that the evidence-based principles of Contextual Behavioural Science can be delivered more easily and with greater thoroughness and precision. You will learn multiple interventions that align precisely with the Spectrum of Selves as described in Henry’s recent publication in Frontiers in Psychiatry, and that can be applied throughout the three phases of Psychedelic-assisted therapy. Much of the focus will be on psychedelic integration in that this phase of work is the most extended, and can also be applied in a normal private practice with clients who experienced psychedelics beyond your practice.

Rob Krause was a co-therapist and co-facilitator during the development of this approach, gave input on peak states to the Spectrum of Selves paper and will share his perspectives and as well as his professional and research experience with psychedelics

Larry gave input on archetypes to the Spectrum of Selves paper and will continue share his perspectives including from Hakomi and MAPS training points of view.

This extended training will include:

  • A 150 page manuals to support you during and after the training.
  • A full certificated training in TIR, a structured approach to Trauma/PTSD comparable to EMDR in its thoroughness and precision, yet more consistent with mindfulness and ACT.
  • ACT-informed Parts work to address inner conflict between your different selves
  • Differentiating between healthy and unhealthy self-story/narcissism
  • An experiential protocol for processing intense psychedelic experiences and re-accessing perspectives and insights from the experience.
  • Expanding and reinforcing new behavioural repertoires that flow from new perspectives
  • Overcoming complex/long-term trauma (often more accessible post psychedelic)
  • Working Somato-cognitively – reawakening feeling in the body
  • Mapping and reinforcing systemic change.
  • Inner healing intelligence versus active-directive interventions (when to do which)
  • Working with malevolent parts and archetypes
  • Unsticking stuck clients with advanced ‘defusion’ techniques (during and after a psychedelic experience)
  • Shame work as a shortcut to our deepest self-concept issues
  • Perspective switching exercise for transcending the polarities of the mind
  • Behaviour change coaching for increasing alignment in a person’s life.

All these methods are integrated into a package for retaining and further developing the gains from Psychedelic healing experience.
