The 21 DASS-21 items
The scale asks how much each statement applied to you over the past week. Each item is rated on a 4-point scale:
0 = Did not apply · 1 = Applied to some degree · 2 = Applied to a considerable degree · 3 = Applied very much or most of the time
The 21 items load onto three 7-item sub-scales:
- Depression (D): items 3, 5, 10, 13, 16, 17, 21 — hopelessness, anhedonia, devaluation of life, self-deprecation, lack of interest, inability to experience positive feelings.
- Anxiety (A): items 2, 4, 7, 9, 15, 19, 20 — autonomic arousal (dry mouth, breathing difficulty, trembling), situational anxiety, subjective experience of anxious affect.
- Stress (S): items 1, 6, 8, 11, 12, 14, 18 — difficulty relaxing, nervous arousal, easily agitated, irritable, over-reactive, impatient.
Each sub-scale total (0-21) is multiplied by 2 to give a final 0-42 score, which is compared against the severity bands.
DASS-21 severity band table
| Band | 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+ |
The three scales are independent — you can be Normal on Depression and Severe on Anxiety, or vice versa. Read your result as three separate signals, not one composite.
How the DASS-21 was developed
The DASS was developed by Peter F. Lovibond and Sydney H. Lovibond at the University of New South Wales in 1995. It emerged from factor-analytic work on a large item pool designed to distinguish depression from anxiety (the two constructs are highly correlated in most self-report scales, and clinicians wanted a tool that separated them cleanly). The three-factor solution — Depression, Anxiety, and a distinct third "Stress" dimension covering persistent non-specific tension — has been replicated in 50+ confirmatory studies across five continents.
The DASS-21 is the short form derived from the original 42-item DASS. Both versions preserve the three-factor structure with excellent internal consistency (Cronbach's alpha typically 0.87-0.94 across sub-scales in Indian samples).
Indian validation studies at NIMHANS, AIIMS, Delhi, and multiple state medical colleges have confirmed factor structure, severity band accuracy, and cross-linguistic equivalence across Hindi, Kannada, Tamil, and English.
DASS-21 vs other combined-symptom scales
| Test | Items | Time | What it measures | Indian validation |
|---|---|---|---|---|
| DASS-21 | 21 | 4 min | Depression + Anxiety + Stress, three separate scores | Yes |
| K10 | 10 | 2 min | Non-specific distress, single score | Yes |
| GHQ-12 | 12 | 3 min | General psychological distress, single score | Yes |
| PHQ-9 + GAD-7 | 16 | 5 min | Depression + Anxiety, separately | Yes |
| DASS-42 | 42 | 8 min | Same three factors as DASS-21, longer form | Yes |
Use the DASS-21 when you want three separate signals (Depression, Anxiety, Stress) in one short test. Use PHQ-9 + GAD-7 when depression or anxiety is your specific focus and you want the strongest treatment-monitoring instruments. Use K10 or GHQ-12 when a single distress score is enough (e.g. large-scale screening).
When to act on your result
- All three Normal: No action needed. Retake in 4-6 weeks if life circumstances change.
- Any sub-scale Mild: Behavioural activation, sleep hygiene, mindfulness. The CBT Thought Record and Progressive Muscle Relaxation are evidence-based for this band. Retake in 2-4 weeks.
- Any sub-scale Moderate: Clinical evaluation recommended. Book a Mindtalk psychologist or psychiatrist. CBT is first-line for Depression and Anxiety; stress-management protocols work for elevated Stress.
- Any sub-scale Severe or Extremely Severe: Clinical evaluation needed within the week. Combination therapy is often indicated for Depression and Anxiety. Consider the 90-day Depression-Anxiety-Stress journey or Emotional Reset programme.
- Any Extremely Severe result: Urgent clinical evaluation. If mood is very low, take the PHQ-9 to check for self-harm risk (DASS-21 does not screen this).
After the DASS-21
- Track over time. Retake every 2-4 weeks during treatment. The three sub-scores respond at different rates — Anxiety often improves first, Stress is usually most persistent.
- Pair with condition-specific scales. Pair a high Depression score with the PHQ-9 for treatment monitoring and self-harm screening. Pair a high Anxiety score with the GAD-7.
- Start a structured programme. The 90-day Emotional Reset programme suits sub-clinical DASS-21 profiles (Mild-Moderate on any scale). The Anxiety Loop Breaker suits Moderate-Severe Anxiety.
- Book a specialist. Mindtalk's psychologists and psychiatrists treat depression, anxiety, and stress-related presentations across Bangalore, Hyderabad, Mysore, and online for anywhere in India.

Frequently Asked Questions
- What is the DASS-21 designed to measure?
- Three distinct-but-related emotional states: depression (hopelessness, anhedonia, devaluation of life), anxiety (autonomic arousal, situational anxiety, subjective fear), and stress (persistent non-specific arousal, tension, impatience). The three-factor structure has been replicated in over 50 confirmatory factor-analytic studies including Indian samples. This makes it distinct from single-construct scales like the PHQ-9 (depression only) or GAD-7 (anxiety only).
- What are the DASS-21 severity bands?
- Bands differ per sub-scale (final scores after the ×2 multiplier). Depression: Normal 0-9, Mild 10-13, Moderate 14-20, Severe 21-27, Extremely Severe 28+. Anxiety: Normal 0-7, Mild 8-9, Moderate 10-14, Severe 15-19, Extremely Severe 20+. Stress: Normal 0-14, Mild 15-18, Moderate 19-25, Severe 26-33, Extremely Severe 34+. Anxiety cut-offs are lower because the scale focuses on physical-arousal symptoms, which are more discriminating at lower levels.
- DASS-21 vs PHQ-9 and GAD-7 — which should I take?
- Take the PHQ-9 if depression is your only concern and you want the global gold-standard for treatment monitoring. Take the GAD-7 if generalised anxiety is your only concern. Take the DASS-21 if depression, anxiety, and stress overlap — which is roughly 60% of clinical presentations. Many Mindtalk clinicians use PHQ-9 + GAD-7 for treatment tracking (because each has stronger response sensitivity) and DASS-21 at intake (because it maps the whole emotional-symptom landscape in one 4-minute test).
- Is the DASS-21 validated in India?
- Yes. Multiple Indian validation studies have replicated the three-factor structure in student, community, and clinical samples across Hindi, Kannada, Tamil, and English administrations. The DASS-21 is used routinely in NIMHANS research and clinical practice, and by Cadabams' clinicians at intake for adult mental-health presentations.
- Why does the DASS-21 have no self-harm question?
- The DASS-21 was designed as a research and screening instrument focused on the core dimensions of depression, anxiety, and stress — not as a comprehensive risk assessment. It does not screen for self-harm, suicidal ideation, psychosis, or mania. If suicide safety is a concern, pair it with the PHQ-9 (Question 9 screens for self-harm) or the C-SSRS (Columbia Suicide Severity Rating Scale). The Mindtalk app routes users showing high DASS-21 Depression to a follow-up C-SSRS if flagged by their clinician.
- How is the DASS-21 different from the DASS-42?
- The DASS-21 is the short form of the original 42-item DASS. Scores on the 21-item version are multiplied by 2 to align severity bands with the 42-item scale — this preserves comparability with the older literature. Both versions produce equivalent factor structures and severity classifications in published validation studies. The 21-item version is standard in clinical use because it takes half the time with no meaningful loss of information.
- How do I take the DASS-21?
