What Is the DASS-21?
The Depression Anxiety Stress Scales (DASS-21) is a 21-item clinical instrument developed by the University of New South Wales. It measures three related but distinct constructs:
Each item is scored 0-3 based on the past week. Scores are doubled to match the full DASS-42 scale.
How to Read Your Scores
| 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+ |
Important: These are screening ranges, not diagnoses. A high score means further assessment is warranted — it doesn't mean you have a clinical disorder.
What Each Subscale Tells You
Depression subscale measures the core features of depressive experience: feeling like life is meaningless, unable to experience positive emotion, feeling worthless, lacking initiative. High scores here suggest anhedonia (inability to feel pleasure) is a significant factor.
Anxiety subscale focuses on physiological arousal: trembling, dry mouth, breathing difficulties, heart racing. This distinguishes clinical anxiety from general worry. High scores suggest your body's fight-or-flight system is overactivated.
Stress subscale captures nervous arousal, difficulty relaxing, and being easily upset or agitated. Unlike anxiety, stress here relates to chronic tension rather than acute fear responses. High scores suggest sustained overload.
Why This Matters for Adjustment Difficulties
Adjustment difficulties rarely show up as pure depression or pure anxiety. They typically present as a mixed profile — moderate stress, mild-to-moderate anxiety, and fluctuating depression scores. The DASS-21 captures this mixed presentation better than single-construct instruments.

Taking Action on Your Results
The DASS-21 takes approximately 5 minutes to complete. That's 5 minutes for objective clarity on where you stand.
