Working with Psychic Equivalence

Working with Psychic Equivalence
Mentalization-Based Treatment (MBT)
💡 Clarification 🧠 Cognition

A technique for working with the non-mentalizing mode in which the client's inner reality is experienced as outer: what is thought and felt is taken as absolute truth. There is no gap between thought and reality. The client is absolutely sure of their interpretation and feels deep emotional pain without the possibility of seeing the situation otherwise. The therapist cannot directly contest the beliefs — first the arousal must be lowered and a "gap" between thought and reality created.

Step-by-step guide

  1. Recognize markers: absolute formulations ("he definitely.", "I know for sure."), the impossibility of considering an alternative, intense pain
  2. Do NOT contest the client's beliefs directly — this will increase rigidity
  3. Empathically validate the experience: "I see how real and painful this is for you"
  4. Slowly introduce the element of "as if": "Suppose for a moment that another option is also possible."
  5. Use the not-knowing stance: "It is hard for me to be sure — tell me what makes you think so?"
  6. Gradually widen the space for alternative interpretations

When to use

  • When the client is absolutely sure of their interpretation of the situation, without any doubt
  • When the client says: "I know for sure what he was thinking / what she was feeling"
  • When the client's certainty causes intense distress

Key phrases

I see that for you this is absolutely real. Tell me what exactly makes you so sure.

Follow-up questions

This is really very painful. And is there even a small chance that something could have been different?
Suppose for a second that this is not the only explanation. What would that change for you?

Alternative phrasings

It is hard for me to be that sure. Help me understand where this certainty comes from.

Warnings

  • ⚠️ Direct contestation of beliefs in psychic equivalence WILL amplify the distress and the rigidity
  • ⚠️ Work slowly and carefully — change can take many sessions
  • ⚠️ Begin with validation, not with challenge — the client needs to feel understood
