The therapist disciplinedly uses their authentic reactions as an instrument: showing the client how their behavior affects another person.
Step-by-step guide
- Notice your reaction: what are you feeling right now with this client?
- Assess: is it informative? Will it help the client see their effect?
- Share it disciplinedly: "When you looked away and went silent — I felt sad"
- Connect to the purpose: "Is that the effect you want to have on people?"
- Positive DPI: "When you just looked at me and said it directly — I felt warmth. That is a different effect"
- Check: "How is it for you to hear that?"
When to use
- When the client's in-session behavior illustrates their pattern
- With new adaptive behavior (reinforcement)
Key phrases
I want to give you something you have been cut off from — real feedback about your effect on another person. Right now, when you went quiet, I felt further away from you. I am telling you that so you can see what happens for the person on the other side.
Follow-up questions
Is that the effect you want to have on people?
What do you think happens for others in your life when you do this?
When you did the new thing a minute ago — I felt closer. Can you feel that difference?
How is it for you to hear me say this?
Alternative phrasings
I share this in service of you, not of me.
If this feels like too much, tell me — we can slow down.
Warnings
- ⚠️ DPI is not "say everything you think". It is a disciplined instrument.
- ⚠️ Every disclosure is in the client's interest.
