The Clinical Outcomes in Routine Evaluation-10 (CORE-10) is a 10-item self-report questionnaire that measures common psychological distress in adults over the past week. It samples anxiety, depression, trauma, and physical problems alongside day-to-day functioning and one risk item, giving practitioners a short global index of distress for screening and for tracking change across an episode of care.
Why healthcare providers use the CORE-10
- Brief to complete. Ten items take two to three minutes, so it fits into routine appointments and repeated administration.
- Tracks change over time. Its short format supports session-by-session monitoring of distress across care.
- Includes a risk item. One item asks about thoughts of self-harm, prompting follow-up when concerns are present.
- Validated global index. It provides a single, research-backed measure of psychological distress that guides clinical decision-making.
Which settings use the CORE-10?
- Primary care and talking-therapy services. Used in stepped-care settings to screen and monitor common mental health presentations.
- Counselling and psychotherapy. Practitioners administer it at intake and across sessions to track client progress.
- Community mental health teams. Applied as a brief routine outcome measure alongside broader assessment.
What does the CORE-10 measure?
The CORE-10 samples psychological distress across several domains drawn from the longer CORE-OM. It combines symptom-focused items with questions about everyday functioning and one risk item, producing a global picture rather than a single-diagnosis score. It contains six problem items, three functioning items, and one risk item.
- Subjective distress. Anxiety, depression, trauma symptoms, and physical problems experienced over the past week.
- Day-to-day functioning. How distress affects coping, activities, and close relationships.
- Risk to self. A single item screening for thoughts of self-harm.
Scoring the CORE-10
- Number of items: 10 self-report items.
- Per-item scale: each item is scored 0 to 4, from not at all to most or all of the time, with two items reverse-scored.
- Total score range: 0 to 40 when all 10 items are summed.
- Score direction: higher scores indicate greater psychological distress.
A total score of 11 or above is the recognised clinical cutoff, indicating clinically significant distress. Scores can also be expressed as a mean for comparison with the CORE-OM. The measure supports screening and monitoring; it does not provide a diagnosis, and results should be interpreted alongside clinical judgement.
| Score | Interpretation | Suggested next step |
|---|---|---|
| 0 to 5 | Healthy, minimal distress | Routine monitoring |
| 6 to 10 | Low-level distress, below clinical cutoff | Watchful waiting |
| 11 to 14 | Mild distress, clinical range | Consider further assessment |
| 15 to 19 | Moderate distress | Consider further assessment |
| 20 to 24 | Moderate-to-severe distress | Prompt clinical review |
| 25 to 40 | Severe distress | Prompt further evaluation |
Best practices for administration
- Keep a consistent recall window. The CORE-10 asks about the past week, so administer it against the same timeframe each time.
- Re-administer at regular intervals. Repeat at intake and across sessions to make change scores meaningful.
- Review the risk item promptly. Check the self-harm item on every submission and follow your escalation protocol when it is endorsed.
- Handle omitted items correctly. If one item is missing, prorate the score; do not score forms with more than one item blank.
- Explain the purpose. Tell patients the questionnaire tracks how they have been feeling so responses are candid.
How Zentake helps with the CORE-10
- Automatic scoring. Totals are calculated on submit, with no hand-tallying.
- Longitudinal tracking. Re-send the CORE-10 on a schedule and view change over time.
- Risk flagging. Concerning responses, including the self-harm item, are surfaced to staff.
- Before the visit. Patients complete it from home on any device, so mental health practices start informed.
- HIPAA compliant. Data is encrypted, with a signed BAA on every plan.

The CORE-10 was developed and validated by Barkham and colleagues (2013) in Counselling and Psychotherapy Research as a short form of the CORE-OM for common presentations of psychological distress. The clinical cutoff of 11 and the severity bands derive from this validation work and the accompanying scoring guidance.
