Which mental health self-test should I take first?

Answered by Dr. Nitnem Singh Sodhi · Consultant Psychologist & Psychotherapist · Updated 2026-05-05

Short answer

Start with K10 if unsure (general distress). Use PHQ-9 for low mood, GAD-7 for anxiety, ISI for sleep, PSS-10 for stress, AUDIT-C for alcohol, ASRS for adult ADHD, OCI-R for OCD, PC-PTSD-5 for trauma, WHO-5 for general wellbeing.

All screeners on this site are the publicly documented, validated instruments — same item sets and same scoring as clinic. Pick by what you are actually trying to check.

If you are not sure where to start

Take the K10. It is a 10-item general distress screener and gives a clean read on whether anything needs deeper attention.

Targeted screeners

Low mood, loss of interest → PHQ-9. Worry, restlessness, racing thoughts → GAD-7. Sleep onset / maintenance trouble → ISI. Feeling overwhelmed by life load → PSS-10. Concern about alcohol → AUDIT-C. Adult attention or focus → ASRS-v1.1. Intrusive thoughts or rituals → OCI-R. Past traumatic event → PC-PTSD-5. General wellbeing baseline → WHO-5.
