Change talk vs sustain talk: examples and DARN-CAT

Change talk is anything a person says in favor of change: wanting it, being able to, having reasons, or needing to. Sustain talk is the opposite: their reasons for keeping things the same. Most people say both in the same breath. In motivational interviewing you listen for change talk, respond so they say more of it, and avoid arguing with the sustain talk.

Why the difference matters

People tend to act on what they hear themselves say. Research on MI conversations has linked the balance of change talk and sustain talk to what people later do, which is why MI puts so much attention on hearing and drawing out change talk.

Ambivalence sounds like a person arguing with themselves. Your job is to notice which side is speaking and to give the change side more room. If you jump in and argue for change yourself, the person will usually take up the other side, and you end up drawing out sustain talk.

DARN-CAT: the types of change talk

Miller and Rollnick sort change talk into two groups.

Preparatory change talk (DARN)

This is talk about change before the person has decided anything.

• Desire: wanting, wishing, liking. "I want to get back to where I was last year." "I'd love to stop finishing notes at home."
• Ability: what they could do. "I could block the first slot after lunch for catch-up." "I could probably walk on my lunch break."
• Reasons: specific benefits of change or costs of not changing. "My last patients always get the rushed version of me." "If I quit, I'd stop wheezing on the stairs."
• Need: urgency, without saying why. "I have to get my reports in on time." "Something's got to give."

Mobilizing change talk (CAT)

This is talk that leans toward action.

• Commitment: intention or promise. "I'm going to talk to finance about the template this week." "I will call the clinic tomorrow."
• Activation: willingness or readiness, short of a promise. "I'm ready to try it." "I'd be willing to use the pill organizer."
• Taking steps: something they've already done. "I bought nicotine patches." "I moved my standing meeting so I'd have time for reviews."

You'll often hear DARN before CAT. A rise in commitment and activation language is one sign the person may be ready to talk about a plan.

What sustain talk sounds like

Sustain talk mirrors the same categories, pointing the other way.

• Desire: "I like having a drink to unwind."
• Ability: "I can't find the time."
• Reasons: "Nobody reads those reports until the tenth anyway."
• Need: "I need the cigarettes to get through a double."
• Commitment: "I'm not changing how I chart."

Sustain talk is normal. It doesn't mean the person is difficult or the conversation is failing. It tells you what the barriers look like from their side.

Spotting both in one statement

Real speech mixes the two, often in the same sentence. Here's a provider who often runs late.

Running behind is just how primary care works. I've been doing it this way for twelve years. I hate that my last patients of the day always get the rushed version of me, though. I could probably block the first slot after lunch for catch-up.

Sort it:

• "Running behind is just how primary care works." Sustain talk (reasons).
• "I've been doing it this way for twelve years." Sustain talk.
• "I hate that my last patients get the rushed version of me." Change talk (reasons, with some desire).
• "I could probably block the first slot after lunch." Change talk (ability).

If you only heard the first half, you might start arguing that primary care doesn't have to run late. The change talk came after the sustain talk. Listening to the end pays off.

Responding to change talk: EARS

When you hear change talk, MI suggests four responses, remembered as EARS. They're OARS pointed at change talk.

Elaborate

Ask for more detail or an example.

I'd like to not be scrambling every morning. I just don't know how.

What would a morning look like if you weren't scrambling?

Notice what the supervisor left alone: "I just don't know how." That's sustain talk, and it can wait.

Affirm

Recognize the strength or value behind what they said.

I've already switched to diet soda at lunch.

You found a change you could make on your own and you stuck with it.

Reflect

Say the change talk back so they hear it again, sometimes with a little more meaning.

I know the team can't close the month without my reports. I don't love being the bottleneck.

Being someone the team can count on matters to you.

Summarize

Gather several pieces of change talk together, sometimes called a bouquet. Hearing their own reasons side by side can have a strong effect on people.

So you'd like to stop getting winded on the stairs, you've already cut back to half a pack, and you want to be around for your granddaughter's graduation. What do you make of all that?

Mixed statements: reflect the change side

When a statement has both, you choose which side to reflect. Reflecting the sustain side invites more sustain talk. Reflecting the change side invites more change talk.

It's not like I'm ignoring them. I just get buried. Although, yeah, Mr. Patel waiting two weeks for a callback wasn't okay.

You get buried, and it's hard to keep up.

You don't want patients waiting that long to hear back.

The first reflection isn't wrong, and it might be the right call if the coordinator seemed defensive. But it keeps the conversation on the workload. The second follows the change talk.

If you need to acknowledge both sides, use a double-sided reflection and put the change side last: "You're buried, and you also don't want patients like Mr. Patel waiting two weeks."

Evoking change talk on purpose

You don't have to wait for change talk. Some questions tend to draw it out.

• Desire: "What would you like to be different?"
• Ability: "If you decided to do this, how might you go about it?"
• Reasons: "What would be the good things about making this change?"
• Need: "How important is this to you right now?"
• Looking back: "What were things like before the extra shifts started?"
• Looking forward: "If nothing changes, what do you imagine a year from now?"
• The importance ruler: "On a scale of 0 to 10, how important is this to you?" followed by "Why that number, and not a lower one?"

Avoid "Why not higher?" It invites the person to list reasons against change.

From change talk to planning

As change talk builds, you'll notice the conversation shift. MI describes a few signs that someone may be ready to talk about a plan:

• Less sustain talk, and what's left sounds weaker.
• More mobilizing language: "I'm going to," "I'm ready," "I already started."
• Questions about how: "So what would I even do first?"
• Imagining the change: "If I blocked that slot, I could actually eat lunch."
• A quieter, more settled tone, as if something has been decided.

When you hear these, test the water with a transitional summary and a key question.

You'd like mornings to feel less chaotic, you've noticed the trouble starts when the rooms aren't stocked the night before, and you think you could take that on before you leave. Where does that leave you?

If the answer is a plan, help them build it in their own words. If it's more ambivalence, go back to evoking. Neither answer means you failed.

Common mistakes

• Pouncing. When you finally hear change talk, it's tempting to leap into a plan. "Great, so let's set up a schedule." One piece of change talk is rarely enough. Reflect it and let them build.
• Arguing with sustain talk. "But you said you hate rushing patients" turns their own words into ammunition. Reflect the sustain talk instead; see how to respond to sustain talk.
• Missing the quiet ones. Change talk is often small and hedged: "I guess I could," "Maybe." Those count.
• Treating "I should" as commitment. "I should" usually signals need or outside pressure, not a decision.

Putting it into practice

The fastest way to get better is to listen for change talk in conversations you aren't leading: meetings, podcasts, a colleague's phone call. Tally each piece of change talk and sustain talk you hear. Once you can hear it, start responding with one EARS move at a time.
