What Is a SUDS Score? And Why Does It Matter So Much?

SUDS stands for Subjective Units of Distress Scale. It was developed by psychologist Joseph Wolpe in the 1950s as a simple way of measuring the intensity of emotional distress — a number from 0 to 10 that represents how strongly a feeling or physical sensation is present in this moment. Zero means no emotional charge at all. Ten means the maximum intensity imaginable.

It sounds almost too simple to be significant. But in EFT tapping — and particularly in using EFT with children — the SUDS scale is one of the most transformative elements of the entire method. Here is why, and exactly how to use it.

Why Measuring the Feeling Matters

Anxiety, by its nature, feels permanent and boundless when you are inside it. This is one of its most distressing qualities — not just the feeling itself, but the sense that the feeling has no edges, no end, no possibility of being different. Children who live with anxiety often describe it as "just how I am" — a fixed state rather than a temporary experience that can change.

The moment you give a feeling a number, something fundamentally important shifts. The feeling is no longer boundless and permanent. It has a measurable size. And if it has a measurable size, it can change. Watching a number that was 8 become 5, then 3, then 1 provides children with something uniquely powerful: evidence, felt in their own body, that feelings are not fixed. That they can move. That they can clear.

For parents, the SUDS scale provides a window into their child's internal experience that conversations often cannot. A child who says "I'm fine" may rate their distress at a 7 on the scale. A child who is in tears may be surprised to find they are already at a 4. The number gives both parent and child a shared reference point that is grounded in real, moment-to-moment experience rather than the stories we tell about how we feel.

How to Explain SUDS to a Child

When introducing the SUDS scale to a child for the first time, simplicity matters. Here is a way that works well across a wide age range:

"Think about the thing that's worrying you right now. Really think about it — where do you feel it in your body? If zero means you feel completely calm about it, like it's not there at all, and ten means it feels as big and awful as it possibly could, what number does it feel like right now? Just go with the first number that comes into your head."

Don't overthink it, and don't let your child overthink it either. The first number is almost always the right one. The SUDS scale is subjective by design — it measures your experience, not some objective standard. A 7 for one child may feel very different in quality from a 7 for another child, and that is entirely fine. What matters is internal consistency: that the same child's 7 means roughly the same thing each time they use the scale.

For younger children or children who find the numerical concept difficult, visual aids can help — a simple 0 to 10 thermometer drawn on paper, asking them to show with their hands how big the feeling is, or using a colour scale from calm blue to intense red. The principle is the same. What you need is a reference point that can be compared across time.

What the Numbers Actually Mean

These descriptions are guides, not rules. Every person's experience of each number is slightly different. What matters most is not where on the scale you start, but that you start — and that you keep tapping until you reach 0 or 1.

When to Take a SUDS Reading During a Session

In The Journal Tapping Method, SUDS readings are taken at three key points in every session, and then repeatedly until the session is complete.

First reading — immediately after writing. When you finish your journal entry, the memory or feeling you have been writing about is fully present in the nervous system. The act of writing activates it. This is the right moment to measure — when the charge is as accessible as it will be. This becomes your starting number.

Second reading — after the first three rounds of tapping. Nova asks for your SUDS after every three complete rounds. Three rounds is the minimum needed to give the nervous system enough time to begin regulating before you assess what has shifted. Checking after every single round doesn't give the process enough time to work. Three rounds is the sweet spot.

Ongoing readings — after every subsequent three rounds. If the SUDS is still above 1, Nova immediately builds a new script and continues tapping. This cycle repeats — three rounds, SUDS check, new script if needed — until the score reaches 0 or 1. Only then is the session complete.

This is important: the session always continues to 0 or 1. Not to 3 or 4 because "it feels much better." Stopping at a SUDS of 3 means the emotional charge has reduced but not fully cleared. The nervous system has not fully processed the experience. A SUDS of 0 or 1 means the work is genuinely done for this session.

What to Do When the SUDS Does Not Drop

Occasionally, after several rounds of tapping, the SUDS remains stubbornly high or barely moves. This is not a sign that EFT isn't working — it almost always indicates one of a small number of specific situations that are easy to address once you know what to look for.

The focus has shifted. This is the most common reason. Mid-session, as the initial layer of emotion begins to clear, new aspects of the issue often emerge. You started on "the argument with my friend" and your mind has drifted to "feeling generally left out at school." These are related but different targets. The tapping is still working — it has just moved onto new territory. If this happens, name the new aspect and start a fresh round focused specifically on it.

The target is too broad or vague. "I'm anxious about everything" doesn't give the nervous system enough specificity to work with. The more precisely you can define the target — a specific moment, a specific memory, a specific physical sensation — the more effectively the tapping can address it. If the SUDS isn't moving, try narrowing the focus. Instead of "school anxiety," try "that moment yesterday when I had to read out loud and my voice shook."

There is a secondary emotion underneath. Sometimes clearing the surface layer of emotion reveals a deeper layer beneath. A child may start on "I'm angry at my teacher" and, once the anger clears, discover that underneath is "I feel humiliated and invisible." The deeper layer needs its own dedicated rounds. This is a sign of real progress, not a problem — the process is working exactly as it should.

The body needs time to integrate. If the SUDS genuinely will not move after many rounds, it may be worth taking a break — even a day or two — and returning to the issue in a new session. Sometimes the nervous system needs time between sessions to integrate the work that has already happened before it is ready to release further.

SUDS and the Personal Peace Procedure

The Personal Peace Procedure — the members-only feature of The Journal Tapping Method — uses SUDS tracking across multiple sessions and multiple memories over time. Each memory on your Personal Peace Procedure list has an initial SUDS score and a current SUDS score. Every time you tap on a memory, the current score updates. You can watch, over weeks and months, as memories that once scored 9 settle gradually to 3, then to 1, then to 0.

This longitudinal tracking is deeply meaningful for many people. It transforms what can feel like an endless and overwhelming task — addressing a lifetime of difficult memories — into something manageable and measurable. One memory at a time. One SUDS point at a time. Each session a small, real, recorded piece of progress.

The Deeper Gift of SUDS — Emotional Ownership

Beyond its practical function in tracking session progress, the SUDS scale gives children something far more valuable over time: a direct experience of their own capacity to influence how they feel.

A child who has watched their own SUDS drop from 9 to 1 — who has felt that shift in their body, not just been told it happened — carries a different internal story about themselves and their emotions. Not "feelings happen to me and I cannot control them" but "feelings have a size, and I have something that changes the size." This is not a minor shift. It is the foundation of genuine emotional resilience.

Children who develop this relationship with their emotional experience — who learn to observe, measure, and actively work with their feelings rather than being overwhelmed by them — navigate difficulty differently throughout their lives. They recover from setbacks more quickly. They are less derailed by emotional intensity. They trust themselves to handle what comes. That is the deepest gift of the SUDS scale — not the number itself, but what learning to use it teaches about the nature of feelings and the capacity of the human nervous system to heal.

"The first time a child sees their own SUDS drop from 8 to 1, everything changes. They have experienced proof — felt in their own body — that they can change how they feel. That proof lasts."
