That number is a measure of psychological distress, a broad term that covers feeling worn down, tense or low. Here is how the score is built and how it is usually read.
At a glance
- The K10 has ten questions about the past 30 days, each scored 1 to 5, so totals run from 10 to 50.
- Commonly used groupings read 10–19 as low, 20–24 as mild, 25–29 as moderate and 30–50 as severe distress.
- It measures general distress, not a specific condition. It is a screening tool, not a diagnosis.
What does the K10 measure?
The Kessler Psychological Distress Scale was developed by Ronald Kessler and colleagues and published in 2002. It was built as a short screening scale for large health surveys, first for the redesigned US National Health Interview Survey, and it was used in the 1997 Australian National Survey of Mental Health and Well-Being. A six-question short form, the K6, sits inside it.
Psychological distress means the everyday weight of anxious and low feelings, without pinning them to one diagnosis. The ten questions cover topics such as tiredness without a clear reason, nervousness, restlessness, low mood, hopelessness, feeling that everything takes effort, and feeling worthless. In the original study, the scale clearly separated people with and without mental health conditions identified in clinical interviews.
How is the K10 scored?
Each question asks how often you felt a certain way during the past 30 days. The answers are scored like this:
- None of the time scores 1.
- A little of the time scores 2.
- Some of the time scores 3.
- Most of the time scores 4.
- All of the time scores 5. Add all ten answers for a total from 10 to 50.
Because the lowest answer is worth 1, nobody scores below 10. A score of 10 means you answered “none of the time” to every question.
K10 score ranges
| Total score | Commonly used grouping | What it suggests |
|---|---|---|
| 10–19 | Low distress | Feelings of strain have been occasional or mild |
| 20–24 | Mild distress | Strain shows up regularly; worth paying attention to |
| 25–29 | Moderate distress | Distress is frequent; talking it over with someone is a good idea |
| 30–50 | Severe distress | Distress is present most of the time; reaching out for support matters |
These ranges are groupings commonly used to read K10 results, and they are the ones our check uses. Different services sometimes draw the lines slightly differently, so treat the label as a guide to how heavy the past month has been rather than a fixed category.
What does my K10 score mean?
A score of 22, for example, falls in the mild range: some of the feelings on the list have been showing up a fair amount of the time. A score of 32 is in the severe range and means distress has been part of most days. Two things help you get more out of the number:
- Look at which questions scored highest. High scores on nervousness and restlessness point toward anxiety; high scores on hopelessness and low mood point toward depression. For a closer look, see anxiety tests compared or the depression test guide.
- Retake it in a month. The K10 is about the past 30 days, so repeating it shows whether things are easing or building up.

A distress score tells you how heavy things have been, not why. The next useful step is to put words to what has been weighing on you, which is easier with someone who can ask follow-up questions and remember what you said last time.
CareOps Maeumi is an AI counseling app that starts with short self-checks like the K10 and remembers earlier sessions, so you can pick up where you left off. You can talk by voice or text, and the first session is free. If distress is high, you can use it alongside care from a licensed professional.
Frequently asked questions
- How is the K10 scored?
- Each of the ten questions is scored from 1 (none of the time) to 5 (all of the time), based on the past 30 days. Add them together for a total from 10 to 50.
- What does a K10 score of 25 mean?
- 25 falls in the 25–29 range, commonly read as moderate distress: anxious or low feelings have been frequent over the past month. It is a screening result, not a diagnosis, and talking it over with someone is a good next step.
- What is a normal K10 score?
- Scores of 10 to 19 are commonly grouped as low distress. That does not mean everything is fine, only that the feelings on the list have been occasional over the past month.
- What is the difference between the K10 and the K6?
- The K6 is a six-question short form contained within the K10. Both were published by Kessler and colleagues in 2002 for use in large health surveys.
