Important safety information

What the K10 is
The K10 (Kessler Psychological Distress Scale) is a 10-item self-report screener for non-specific psychological distress — captures overall mental health load without distinguishing depression from anxiety.
Developed by Ronald Kessler and colleagues at Harvard in 2002 for the US National Health Interview Survey. Now used by WHO, Australian Bureau of Statistics, and many national mental health surveillance programmes.
Non-specific distress is deliberate — one instrument that screens for general mental health load is more efficient for population surveys than separate depression + anxiety + stress measures. For clinical assessment following a positive K10, specific measures (PHQ-9, GAD-7, PSS-10) are then used.
K10 bands
Australian standard bands (widely used internationally):
| Score | Distress level | Clinical interpretation |
|---|---|---|
| 10-19 | Low | Likely well |
| 20-24 | Moderate | Mild-moderate mental disorder possible |
| 25-29 | High | Moderate mental disorder likely |
| 30-50 | Very high | Severe mental disorder likely |
K10 25+ has good sensitivity for common anxiety and mood disorders.
What to use instead
The Mindtalk app hosts PSS-10 — Perceived Stress Scale, similar 10-item general-distress-adjacent format. For more specific screening:
- PHQ-9 — depression-specific
- GAD-7 — anxiety-specific
- DASS-21 — combined depression + anxiety + stress
- WHO-5 — general wellbeing (positive-affect focused)
When to see a specialist
- K10 25+
- Persistent distress over weeks
- Functional impairment (sleep, work, relationships)
- Any positive suicidal ideation
- Distress with substance use
Mindtalk's clinicians work across general mental health assessment in Bangalore, Hyderabad, Mysore, and online for anywhere in India.

Frequently Asked Questions
- What is the K10?
- The K10 (Kessler Psychological Distress Scale) is a 10-item self-report screener for non-specific psychological distress. Each item asks how often over the past 4 weeks you have felt various symptoms of anxiety and depression (e.g., "tired out for no good reason," "nervous," "so nervous nothing could calm you down," "hopeless," "restless"). Scored 1-5; total 10-50.
- What does "non-specific distress" mean?
- K10 doesn't distinguish between depression, anxiety, or stress — it captures overall psychological distress across these conditions. This makes it useful for population surveys (efficient screening of mental health load without needing separate depression + anxiety measures) and for general clinical intake (a first pass before more specific assessment).
- What are K10 bands?
- Australian standard bands: 10-19 low distress (likely well), 20-24 moderate distress (mild-moderate mental disorder), 25-29 high distress (moderate mental disorder), 30-50 very high distress (severe mental disorder). Bands vary slightly by country. Higher scores predict presence of mental disorder — K10 25+ has good sensitivity for anxiety or mood disorder.
- K10 vs PSS-10 — which should I take?
- K10 captures general anxiety + depression distress; [PSS-10](/assessments/pss-10) captures perceived stress specifically (how uncontrollable, unpredictable, and overloaded life feels). K10 predicts mental disorder presence more strongly; PSS-10 predicts stress-related health outcomes more strongly. For general self-check, either works. Mindtalk app hosts PSS-10.
- Is K10 validated in India?
- Yes. K10 has been used in Indian mental health surveys and clinical research with translated Hindi, Kannada, and Tamil versions. Cut-offs may shift slightly (Indian samples may show somewhat different distributions than Australian samples) but the instrument works.
- What should I do instead?
- Take the [PSS-10](/assessments/pss-10) — freely available in the Mindtalk app. For depression-specific: [PHQ-9](/assessments/phq-9). For anxiety-specific: [GAD-7](/assessments/gad-7).
