How to Know if EMDR Is Working: Track Your Progress

The clearest way to know if bilateral stimulation is working is to track two simple numbers every time you practice: your distress rating, 0 to 10, before and after, and how true a wanted belief feels, 1 to 7. Log both next to what triggered the session, then look for a trend across several weeks, not any single number.

Maybe you’ve been doing the butterfly hug before bed, or running sessions in an app, for a few weeks now, and you honestly can’t tell if it’s doing anything. Some days feel calmer; other days feel exactly like before you started. Memory is a poor judge of gradual change, which is part of why “how do you know if EMDR is working” is such a common question once the novelty wears off. A short tracking habit, a few minutes at most, answers it with real numbers instead of a vague impression.

What are you actually trying to measure?

EMDR sessions track two things throughout treatment. EMDRIA’s glossary defines the first as SUDS, Subjective Units of Disturbance, running 0 (calm) to 10 (worst distress you can imagine); our guide to the SUD scale walks through how to use it on your own. The second is VOC, Validity of Cognition, running 1 (completely false) to 7 (completely true), for how true a healthier belief feels in your body. A target counts as settled once SUDS is near 0 and VOC is near 7, and EMDRIA’s overview of EMDR’s eight phases describes an entire phase, Reevaluation, built around checking whether that held before starting anything new.

That’s the formal version, with a clinician doing the scoring. Practicing on your own, you’re running an honest, informal copy of the same idea: two numbers, checked before and after, watched for a trend. For the fuller research picture behind why these numbers matter, see how do you know EMDR is working? This guide covers the part that page only touches briefly: actually building the habit of tracking them yourself.

What should you set up before you start tracking?

A tracking habit works best once a few things are already in place, not invented mid-session.

Have a way to calm down ready first. Before you rate anything that stirred you up, know how you’ll settle back down afterward. If you don’t have a go-to yet, our guide to building a calm, safe place walks through the exercise once, so it’s ready when you need it.

Go slow, on one small thing at a time. Track a single, specific, everyday trigger, not your heaviest memory, and keep sessions short. A clear trend on a small target tells you more than one dramatic attempt at something big.

Know your stop point before you need it. If your distress rises above a 7 out of 10 during a session and it won’t settle, stop, ground yourself, and consider working with a professional on that material. Tracking is meant to show you what’s changing, not to talk you into pushing through a session that’s gone sideways.

How do you build a simple tracking system?

1. Pick a format you’ll actually reopen. A plain notebook, a notes app, or the built-in journaling and progress tracking inside EmEase, a self-guided EMDR app, all work, available in the web app. The best format is the one you’ll use again next week, not the fanciest one.
2. Rate your distress before you start. Bring the trigger or thought to mind, loosely, and give it a number, 0 to 10. Note what it is in a few words.
3. Do your round of bilateral stimulation. Eye movements, tapping, the butterfly hug, or audio, whichever you’ve been using.
4. Rate again right after. Same number, 0 to 10, same target. If you’re working with a specific belief you’d rather hold, gut-check how true it feels too, 1 to 7; our guide to the VOC scale explains that half of the measure.
5. Check in again later that day. EMDRIA notes that processing can continue after a session ends, with new thoughts sometimes surfacing over the following day or two, so a same-day or next-day number matters as much as the one right after.
6. Log it in one line. Date, trigger, before-number, after-number, one word on how you feel. That’s enough; you’re leaving yourself a marker, not writing a report. Our guide to keeping a processing journal has a fuller template and prompts if you want more structure than one line.

What should the trend look like over several weeks?

A single session dropping straight to 0 is the exception, not the rule. Real progress looks like a pattern across entries: a trigger that used to open at an 8 now opens at a 4, or the after-number keeps landing lower even when the before-number doesn’t move much yet.

That pattern is worth trusting, not dismissing as wishful thinking. A 2008 study in the Journal of EMDR Practice and Research followed 61 patients through EMDR treatment and found their distress rating, even just from the end of one early session, correlated with an independent clinician’s separate rating of how much better they’d gotten by the end of treatment. The number tracks something real.

It’s also worth not over-reading any single score. A 2025 methods review in Clinics and Practice examined this distress scale’s psychometrics and found real limitations as a single-item measure, exactly the kind of scale you’re using at home. That’s a reason to read your log as a trend across many entries, not to treat one number from one evening as a verdict.

Progress also isn’t a straight line. A 2025 review in Current Opinion in Psychology looked at adverse effects across 51 randomized trials of therapist-led EMDR and found that where effects were reported at all, they were typically described as mild and temporary. A rough week doesn’t cancel a real trend building underneath it.

Numbers aren’t the only thing worth watching. A few plain shifts tend to show up alongside them:

What to notice	What it looks like
The same old trigger	Feels smaller, or takes longer to build, than it used to
Your reaction	You notice the old feeling instead of getting swept into it
Sleep	Steadier, less time spent replaying the thing before you drift off
Recovery time	You settle back to normal faster after something sets you off

Beliefs like “I’m not safe” or “it was my fault” often have roots in something much older than tonight’s trigger. A rising number on a small, present-day version of that belief is real, connected work on that root system, not a stand-in for reprocessing the deeper material itself.

What if your numbers aren’t moving?

A few flat entries early on doesn’t mean much. Give a target several sessions of honest tracking before drawing conclusions, since one or two entries is often still you finding your footing with the technique, not a fair test of it.

If a target genuinely isn’t moving after weeks of consistent tracking, that’s useful information, not a personal failure. Our guide to why EMDR didn’t work walks through the common, fixable reasons: too little time, a target that’s actually standing in for something else, or material that’s heavier than it looked at first.

When should your own tracking tell you to stop?

Your log isn’t just for celebrating progress. Read backward, it’s also an early-warning system.

Stop today’s session if your distress rises above a 7 out of 10 and won’t settle. Ground yourself, and log it as a stop, not a failed attempt.

Stop the solo approach on that target, and bring in a professional, if your log shows a clearer pattern: the same target keeps opening higher than it closed last time, distress is building across entries instead of easing, or a specific memory you didn’t choose starts showing up in your notes. Any of those, written down over several entries, is more convincing than a single hard evening, and it’s exactly the kind of pattern a tracking habit is built to catch early.

The bottom line

Tracking your progress with bilateral stimulation doesn’t need a clinician’s chart to work. Rate your distress before and after, gut-check a belief when one’s involved, write it down somewhere you’ll actually look again, and read the pattern across weeks instead of judging any single evening. The habit is small. What it tells you, over time, is the real answer to whether this is working.
