Build an anxiety hierarchy

List feared situations from least to most distressing before any exposure begins.

Why it works

Graduated exposure works only if the steps are fine-grained enough that each one is tolerable. A hierarchy externalizes the gradient so the nervous system is never flooded — flooding can reinforce rather than extinguish fear. Ordering by subjective distress (often rated 0–100, "SUDs") gives a concrete progression that the brain can process incrementally.

How to do it

1. Write every feared variation of the situation you can think of.
2. Rate each item 0–100 for how distressing it feels right now.
3. Sort them lowest to highest; aim for 10–15 steps with no gap larger than ~10 points.
4. Start desensitization at an item rated 20–30, not at zero.

Evidence

Graduated exposure hierarchies are a foundational element of systematic desensitization, which has strong clinical trial support for specific phobias and moderate support across anxiety presentations. (clinical)

The hierarchy is a delivery scaffold; no trials have isolated it from relaxation training or exposure itself as the active ingredient.

Common mistake

Making the hierarchy too coarse — large gaps between items mean the person jumps from comfortable to overwhelmed, triggering avoidance instead of extinction.
