If you’ve been researching anxiety or depression self-tests, you may have come across “DASS-21” — a name that sounds clinical but is worth understanding, especially if a doctor, counsellor, or online source has mentioned it to you.
What DASS-21 stands for
DASS-21 stands for the Depression, Anxiety and Stress Scale – 21 items, a widely used psychological screening questionnaire developed by researchers Lovibond & Lovibond. It’s one of the most studied self-report scales in psychology, used in clinics and research settings around the world, including Malaysia.
As the name suggests, DASS-21 doesn’t measure just one thing — it looks at three separate but related emotional states:
- Depression — low mood, loss of interest, hopelessness
- Anxiety — physical arousal, worry, fear responses
- Stress — tension, irritability, difficulty relaxing
Each of the 21 questions is scored on a 0–3 scale based on how much a statement applied to you over the past week, and the scores are grouped into the three subscales above.
What DASS-21 is — and what it isn’t
DASS-21 is a screening tool, not a diagnostic instrument. That distinction matters. A screening tool can flag that your symptoms are in a range worth paying attention to; it cannot, on its own, tell you that you have a specific mental health condition. A formal diagnosis requires a clinical interview and professional judgement from a registered psychologist or psychiatrist, who considers your full history, context, and presentation — not just a questionnaire score.
In other words: a DASS-21 result is a useful starting point for a conversation, not an endpoint.
Why people search for a DASS-21 test online
Many people come across DASS-21 because a therapist mentioned it, a university counselling centre uses it, or they’ve seen it referenced in a mental health article and want to understand their own symptoms before deciding whether to seek help. This is a reasonable and healthy instinct — wanting some initial clarity before booking an appointment.
If that’s why you’re here, we’d rather offer you something built specifically to be a safe, private, non-diagnostic starting point: our own free self-check tools, which use plain language and are designed to gently point you toward next steps rather than leave you with a raw, unexplained number.
What to do with a high score
If your symptoms — whether measured by DASS-21, one of our self-checks, or simply how you’ve been feeling — have been persistent, intense, or getting in the way of daily life, that’s a sign it’s worth speaking to a professional. This is true regardless of the exact score on any one questionnaire.
At BeLive in Psychology, an initial consultation includes a proper clinical interview, not just a questionnaire, so you get a fuller and more personal picture than any self-test can offer. If a structured assessment is appropriate, our psychologists use validated instruments as part of a broader clinical process — see our psychological assessment services for more detail.
Frequently Asked Questions
Is DASS-21 free to take?
The original DASS-21 questionnaire is available for research and clinical use under its authors’ terms. Rather than reproduce the exact instrument here, we recommend our own free self-check tools above, which cover similar ground in a format designed for immediate, private use.
Can DASS-21 diagnose depression or anxiety disorder?
No. It is a screening and severity-indicator tool, not a diagnostic one. A qualified psychologist or psychiatrist is needed for an actual diagnosis.
Where can I take a DASS-21 test in Malaysia?
DASS-21 is sometimes used by hospitals, university counselling centres, and private clinics as part of a broader assessment. If you’d prefer a private, professional setting, you can book a consultation with BeLive in Psychology in Petaling Jaya, where a full clinical interview accompanies any structured testing.

DASS-21 is the short form of a 42-item scale, so each of its three subscales is scored from seven items and then multiplied by two to stay comparable with the original. This doubling step is the part most people miss when scoring it themselves.
Each item is rated 0 to 3 for how much it applied to you over the past week:
- 0 — did not apply to me at all
- 1 — applied to me to some degree, or some of the time
- 2 — applied to me to a considerable degree, or a good part of the time
- 3 — applied to me very much, or most of the time
Add the seven items in each subscale, double the result, then read it against the bands below.
Depression subscale
- 0–9 normal
- 10–13 mild
- 14–20 moderate
- 21–27 severe
- 28+ extremely severe
Anxiety subscale
- 0–7 normal
- 8–9 mild
- 10–14 moderate
- 15–19 severe
- 20+ extremely severe
Stress subscale
- 0–14 normal
- 15–18 mild
- 19–25 moderate
- 26–33 severe
- 34+ extremely severe
A note on the labels: “severe” here describes the score, not you, and not a diagnosis. The bands show how your answers compare with the general population over one particular week. A stressful week can lift a score considerably without anything being clinically wrong.
What to do with your DASS-21 result
If your scores land in the normal or mild bands, no action is needed beyond the usual care of yourself. In the moderate range, it is worth watching over the next few weeks and talking to someone you trust. In the severe or extremely severe bands, or if the same elevated result keeps returning, a conversation with a professional is the sensible next step.
You can take a free screening now — our PHQ-9 depression test or GAD-7 anxiety test take about two minutes each, or use the Bahasa Malaysia version. When you would rather speak to a person, our counsellors and psychologists in KL and PJ work in English, Bahasa Malaysia and Mandarin.
