You've taken the DASS-21. You have three numbers in front of you — Depression, Anxiety, and Stress. But what do they actually mean? This guide explains the scoring, what the severity bands tell you, and what to do depending on your results.
What the DASS-21 Measures
The DASS-21 was developed by Lovibond and Lovibond at the University of New South Wales in 1995. It measures three distinct but related dimensions of emotional distress. Depression, in this context, doesnt mean you have clinical depression — it means you scored in a certain range on questions about hopelessness, low mood, lack of motivation, and difficulty experiencing pleasure. Anxiety covers physical arousal symptoms like trembling, dry mouth, and panic. Stress covers difficulty relaxing, nervous energy, irritability, and overreaction.
These three scales are related — most people who score high on one will score somewhat elevated on others — but they measure different things. Someone might have high anxiety but normal depression, or high stress but low anxiety. The pattern matters.
How Scoring Works
The DASS-21 has 21 questions, 7 for each subscale. Each question is scored 0–3 based on how much it applied to you over the past week (0 = not at all, 3 = most of the time). The raw score for each subscale is multiplied by 2 to make it comparable to the full DASS-42. So your final scores range from 0 to 42 for each subscale.
Severity Bands
Your scores fall into severity bands. These are based on large-scale research and tell you how your scores compare to the general population.
| Severity | Depression | Anxiety | Stress |
|---|---|---|---|
| Normal | 0–9 | 0–7 | 0–14 |
| Mild | 10–13 | 8–9 | 15–18 |
| Moderate | 14–20 | 10–14 | 19–25 |
| Severe | 21–27 | 15–19 | 26–33 |
| Extremely Severe | 28+ | 20+ | 34+ |
What "Normal" Means
A score in the "normal" range doesnt mean you're perfectly fine — it means your level of distress is within the range experienced by most of the population. You can still be having a hard time and score normal. The DASS-21 captures the past week only, so a single snapshot doesnt tell the whole story. If you're concerned, trust your instinct over a number.
What "Moderate" and Above Means
Scores in the moderate, severe, or extremely severe range are a signal — not a diagnosis. They suggest you're experiencing more distress than most people, and that professional support could genuinely help. This is exactly the kind of information a GP needs to create a Mental Health Treatment Plan, which gives you access to Medicare-subsidised psychology sessions.
If you scored severe or extremely severe on any subscale, please consider reaching out soon. You can call Lifeline on 13 11 14 any time, or Beyond Blue on 1300 22 4636.
What It's Not
The DASS-21 is a screening tool, not a diagnostic test. It cannot tell you whether you have clinical depression, an anxiety disorder, or any specific condition. Only a qualified professional can make a diagnosis after a thorough assessment. What it can do is give you — and your GP — a useful starting point for a conversation about how you're going.
DASS-21 vs K10 — what is the difference?
Both the DASS-21 and the K10 (Kessler Psychological Distress Scale) are widely used in Australian mental health settings, and both are available as free online tools. The key difference is what they are measuring.
The DASS-21 gives you three separate scores — depression, anxiety, and stress — each scored independently. This is useful when you want to understand whether low mood, anxiety, or stress is the dominant concern, or when you want to track all three over time. It was developed in Australia (University of New South Wales) and is commonly used in research settings.
The K10 gives you a single score measuring general psychological distress. It does not separate depression from anxiety — it captures overall emotional suffering. The K10 is referenced by Services Australia (Medicare) and is commonly used by GPs in formal mental health reviews as part of the Mental Health Treatment Plan (MHTP) process.
| Feature | DASS-21 | K10 |
|---|---|---|
| Scores | 3 separate (depression / anxiety / stress) | 1 total score (0–50) |
| Questions | 21 | 10 |
| What it measures | Three distinct emotional states | Overall psychological distress |
| Medicare / MHTP | Widely used clinically | Referenced by Services Australia |
| Best for | Understanding which dimension is most elevated | GP-based mental health reviews and Medicare |
If you are seeing a GP about your mental health, bring your K10 score — it is the tool most likely to be part of their review process. If you want a more detailed picture across depression, anxiety, and stress, take the DASS-21 and bring all three subscale scores. You can take both: the K10 takes 2 minutes and the DASS-21 takes 5.

What to Do Next
If your scores are in the normal or mild range, you might focus on maintaining your wellbeing — regular exercise, sleep hygiene, social connection, and tools like the Guided Breathing exercise on this site. Consider retaking the DASS-21 in a few weeks to track changes.
If your scores are moderate or above, we'd gently suggest booking a longer GP appointment and bringing your printed results. Most GPs are very receptive to this — it shows self-awareness and makes the conversation much easier. Read our step-by-step MHTP guide for exactly what to say and expect.
Whatever your scores, remember: taking the test was an act of courage. You're paying attention to your mental health, and that matters.
