TITLE
A Spectrum of Selves in action – An integral model for overcoming relapse and increasing effectiveness in Psychedelic-assisted Therapy.

ABSTRACT
The Spectrum of Selves (Whitfield, 2021*) is compatible with contextual-behavioural, somatic and psychodynamic perspectives, and integrates person-centred and active-directive stances into a dynamic context-sensitive approach. Methods that were previously separated on the level of form, can be united on the level of function. This talk offers an overview of this model with example interventions that participants reported as helpful during one-on-one integration therapy following psilocybin truffle retreats for personal growth (n= 66), during a study recently completed through Regent’s University London. Participants give specific examples of how parts work, trauma work, Acceptance and Commitment Therapy and methods to re-access expanded mystical states, were helpful. These help further develop the Spectrum of Selves model. Quantitative and qualitative data from this study might inform how any psychedelic-assisted therapist might reduce relapse and deepen the process of psilocybin-assisted therapy. For example, practices for maintaining a relationship to the psychedelic experience may predict lasting change post six months.

After being a psychological therapist with 20 years experience in trauma work and mindfulness-informed approaches, Henry is now a PhD candidate at Maastricht University’s Department. of Neuropsychology and Psychopharmacology and Visiting Research Fellow at Regents School of Psychotherapy and Psychology. He has spent over 3 and a half years collecting quantitative and qualitative data regarding how a psilocybin and behavioural processes of interact for lasting therapeutic benefit. To process the many thousands of datapoints collected, Henry now collaborates with Steven Hayes' lab at University of Nevada, Reno where they pioneer new statistical methods for analysing longitudinal data - for the new era of ideographic network analysis and precision medicine. Henry is also a passionate integral thinker with many publications on integrating diverse therapeutic models that push to unite all therapy schools into one subject.
