The DASS-21 produces three separate scores — Depression (0–42), Anxiety (0–42), and Stress (0–42) — each classified into five severity levels from Normal to Extremely Severe. It is a screening tool, not a diagnostic instrument. Your scores indicate current symptom levels across these three emotional dimensions and can help guide conversations with a healthcare provider.
What Is the DASS-21?
The Depression Anxiety Stress Scales — 21 Items (DASS-21) is a self-report screening tool developed by Lovibond & Lovibond (1995) at the University of New South Wales, Australia. It is a shortened version of the original 42-item DASS, designed to measure three related but distinct negative emotional states: depression, anxiety, and stress.
The DASS-21 contains 21 items — seven for each subscale. Each item is rated on a 4-point scale (0 = Did not apply to me at all, 3 = Applied to me very much or most of the time) based on the past week. Because the DASS-21 is the short form, each subscale score is multiplied by 2 to allow comparison with the full 42-item DASS norms. This means final subscale scores range from 0 to 42.
Unlike single-dimension tools such as the PHQ-9 (depression only) or the GAD-7 (anxiety only), the DASS-21 provides a profile across all three dimensions simultaneously. This can be especially useful when you're unsure which emotional state is most prominent.
DASS-21 Score Ranges by Subscale
Each of the three subscales has its own severity thresholds. The ranges below reflect the doubled scores used with the 21-item version:
Depression Subscale
| Score | Severity |
|---|---|
| 0–9 | Normal |
| 10–13 | Mild |
| 14–20 | Moderate |
| 21–27 | Severe |
| 28–42 | Extremely Severe |
Anxiety Subscale
| Score | Severity |
|---|---|
| 0–7 | Normal |
| 8–9 | Mild |
| 10–14 | Moderate |
| 15–19 | Severe |
| 20–42 | Extremely Severe |
Stress Subscale
| Score | Severity |
|---|---|
| 0–14 | Normal |
| 15–18 | Mild |
| 19–25 | Moderate |
| 26–33 | Severe |
| 34–42 | Extremely Severe |
Note that the severity thresholds differ across subscales. A score of 12 on the Depression subscale is mild, but a score of 12 on the Anxiety subscale is moderate. Always interpret each subscale using its own cutoffs.
What Each Subscale Measures
The three DASS-21 subscales target distinct aspects of emotional distress, though they are correlated with each other:
Depression: Measures dysphoria, hopelessness, devaluation of life, self-deprecation, lack of interest or involvement, anhedonia (inability to experience pleasure), and inertia. This subscale captures the core features of low mood and motivational loss.
Anxiety: Measures autonomic arousal (dry mouth, breathing difficulty, trembling, heart racing), skeletal muscle effects, situational anxiety, and subjective experience of anxious affect. This subscale emphasizes the physical and physiological symptoms of anxiety more than cognitive worry.
Stress: Measures difficulty relaxing, nervous arousal, being easily agitated or irritable, over-reactivity, and impatience. This subscale captures a state of chronic non-specific arousal — the feeling of being wound up and unable to settle.
Understanding which subscale is elevated can help you and your healthcare provider focus on the most relevant area. It's common for two or even all three subscales to be elevated simultaneously — depression, anxiety, and stress frequently co-occur.
How DASS-21 Scoring Works
Each of the 21 items is rated from 0 (Did not apply to me at all) to 3 (Applied to me very much or most of the time), based on the past week. The seven items for each subscale are summed, then the sum is multiplied by 2 to produce the final score. This doubling allows direct comparison with the norms established for the full 42-item DASS.
For example, if your raw Depression subscale sum is 8 (out of a possible 21), your final Depression score is 16 — which falls in the moderate range. You can take the DASS-21 screening on this site to have the scoring calculated automatically.
DASS-21 vs. PHQ-9 and GAD-7: When to Use Each
The PHQ-9 and GAD-7 are the most widely used clinical screening tools for depression and anxiety, respectively. They are brief, well-validated, and closely aligned with DSM diagnostic criteria. If a clinician needs to screen for one specific condition, these tools are the standard.
The DASS-21 offers a different advantage: it screens three dimensions at once. This is valuable when you're not sure what you're experiencing — when the emotional distress is diffuse and hard to categorize. It's also useful for tracking how depression, anxiety, and stress change relative to each other over time.
Neither approach is superior. The PHQ-9 and GAD-7 are more specific; the DASS-21 is broader. Many people find it helpful to start with the DASS-21 for an overall picture, then follow up with the PHQ-9 or GAD-7 if a particular subscale is elevated.
What to Do With Your DASS-21 Results
Normal scores across all three subscales: Your current symptom levels are within the typical range. This doesn't mean life feels easy — just that the specific symptoms measured by the DASS-21 aren't elevated. If something still feels off, consider screening with a tool that measures a different dimension, such as the DASS-21 stress subscale or a burnout-specific measure.
Mild elevation in one or more subscales: Mild scores suggest symptoms are present but not significantly impairing function. Lifestyle factors — sleep, physical activity, social connection, workload — are the first-line response. Retaking the DASS-21 in 2–4 weeks can help determine whether the elevation is situational or persistent.
Moderate to severe elevation: Scores in the moderate, severe, or extremely severe range indicate symptom levels that may be impacting daily functioning, relationships, or work. Consulting a healthcare provider or mental health professional is recommended. Bring your DASS-21 results to the appointment — they provide a concrete starting point for conversation.
Extremely severe scores: Scores in the extremely severe range reflect significant distress. This is not a diagnosis, but it is a strong signal that professional evaluation is warranted. If you are experiencing thoughts of self-harm, please contact a crisis resource immediately.
Tracking Your Scores Over Time
One of the most valuable uses of the DASS-21 is longitudinal tracking. A single score is a snapshot; repeated scores reveal trends. Because the DASS-21 measures the past week, retaking it every 1–4 weeks provides meaningful data about whether your emotional state is improving, stable, or worsening.
This is especially useful if you are:
- Starting therapy or medication and want to track response
- Making lifestyle changes (exercise, sleep hygiene, stress reduction) and want to measure impact
- Going through a major life transition (job change, relationship change, loss) and want to monitor how you're coping
- Working with a healthcare provider who would benefit from seeing your symptom trajectory
Save or print your results each time you take the screening. Patterns over weeks and months are far more informative than any single score.
Limitations of the DASS-21
The DASS-21 is a well-validated research instrument, but it has important limitations:
- It is not a diagnostic tool. Elevated scores may indicate a clinical condition, but the DASS-21 cannot confirm or rule out a diagnosis. That requires professional evaluation.
- It measures current symptoms only. The DASS-21 captures the past week. It does not assess lifetime history, pattern of episodes, or diagnostic context.
- Anxiety subscale emphasis on physical symptoms. The DASS-21 Anxiety subscale focuses heavily on somatic arousal (trembling, heart racing, breathing difficulty). People whose anxiety is primarily cognitive (persistent worry without strong physical symptoms) may score lower than expected. The GAD-7 may be a better fit for generalized worry.
- Self-report bias. Like all self-report screening tools, accuracy depends on honest and accurate self-assessment.

Frequently Asked Questions
What is a normal DASS-21 score?
A normal DASS-21 score falls in the lowest severity band: 0–9 for Depression, 0–7 for Anxiety, and 0–14 for Stress. These ranges indicate symptoms are within the typical range for the general population. Normal does not mean you cannot benefit from support — it simply means your current symptom level in that area is not elevated.
Is the DASS-21 the same as the PHQ-9?
No. The PHQ-9 is a 9-item screener focused exclusively on depression, aligned with DSM criteria. The DASS-21 measures three dimensions — depression, anxiety, and stress — simultaneously with 21 items. The PHQ-9 is more common in clinical depression screening, while the DASS-21 provides a broader emotional profile across all three domains.
How often should I take the DASS-21?
The DASS-21 asks about symptoms over the past week, so weekly or biweekly retesting is appropriate. Monthly check-ins work well for general monitoring. Many people retake it before and after starting a new intervention — such as therapy, medication, or a lifestyle change — to track whether scores are shifting. Consistent retesting reveals meaningful trends over time.
Can the DASS-21 diagnose depression or anxiety?
No. The DASS-21 is a screening and research instrument, not a diagnostic tool. It can indicate elevated symptoms that may warrant further evaluation, but only a qualified mental health professional can make a clinical diagnosis based on a comprehensive assessment.
