Scale importance and confidence with the readiness ruler

Ask “On a 0–10 scale, how ready are you?” — then ask why not lower.

Why it works

A number turns vague ambivalence into something workable, and the follow-up "why not a lower number?" forces the person to voice the reasons they are already somewhat motivated — more change talk. Asking "why not higher?" would do the opposite, so the direction of the question matters.

How to do it

1. Ask: "How important is this change, 0 to 10?" and separately, "How confident are you that you could, 0 to 10?"
2. Whatever the number, ask "Why are you at a [n] and not a lower number?"
3. Then ask "What would it take to move up one point?" to surface a concrete next step.

Evidence

Scaling/ruler questions are a standard MI tool; they operationalize separating importance from confidence (two distinct drivers of action). Direct outcome evidence for the ruler itself is limited. (mechanistic)

The ruler is a practical device; the underlying mechanism (eliciting self-generated reasons) is what the broader change-talk research supports.

Common mistake

Asking "why aren’t you higher?", which makes the person defend their low motivation and produces sustain talk — the exact opposite of the goal.
