Ego State Therapy
Core Mechanism
Hypnotic accessing of ego states allows negotiation, communication, and integration between dissociated parts of the personality
Ontology
Personality is normally segmented rather than unitary; ego states arise from ordinary differentiation, from introjected others, and from trauma, and they sit on a continuum running from everyday shifts of mood and role to full dissociative identity
Therapeutic Voice
"I'd like to speak with the part of you that feels eight years old right now. Is that part willing to talk?"
View of the Person
Not a single unified self but a federation of states. What feels like 'me' at any given moment is whichever state currently holds the ego's investment, and the boundary between states is permeable rather than fixed.

Each vignette presents the same client through multiple theoretical lenses side by side — showing how Ego State Therapy formulates presenting problems, sets treatment focus, and sounds in the consulting room compared with other approaches. This comparative pedagogy is unique to Epoché Clinical; no other clinical reference systematically formulates the same case across traditions.

Ego state therapy vs. IFS?
Show answer
Both work with 'parts.' Ego state uses hypnosis and psychodynamic theory; IFS uses Self-leadership.
