In Vivo Avoidance Hierarchy Construction
🛡️ Mastery 🧠 Cognition

A PE technique for approaching safe real-life trauma reminders step by step, using a hierarchy and SUDS ratings to reverse avoidance.

Step-by-step guide

  1. Define the immediate clinical target and confirm safety.
  2. Explain the rationale in simple, concrete language.
  3. Choose a manageable first step and set a clear frame.
  4. Track distress, avoidance, body signals, or caregiver response as relevant.
  5. Process what changed and decide the next step.

When to use

  • PTSD with avoidance of safe reminders
  • Preparation or review of exposure homework
  • When SUDS data or avoidance patterns need to guide treatment

Key phrases

Let's work with in vivo avoidance hierarchy construction in a structured way: what are we approaching, what do you expect will happen, and what do you notice as you stay with it?

Follow-up questions

What did you notice while staying with it?
What was different from what you expected?

Alternative phrasings

Let's slow this down and make it specific.
