The Kessler-10 scale is one of the tools used to screen for psychological distress, such as anxiety or depression. This is not intended to provide a diagnosis – only trained health professionals should do this.
Note: your responses to this questionnaire are anonymous. Your scores are not recorded by Health Navigator and we do not capture any information that can identify you.
The Kessler-10 scale was developed for use in the US National Health Interview Survey. It is a short measure of non-specific psychological distress based on questions about the level of nervousness, agitation, psychological fatigue and depression.
Professor Ronald C Kessler of the Department of Health Care Policy, Harvard Medical School is thanked for the use of research on the Kessler-10 funded by US Public Health Service Grants RO1 MH46376, R01 MH52861, RO1 MH49098 and K05 MH00507, and by the John D and Catherine T MacArthur Foundation Network on Successful Midlife Development (Gilbert Brim, Director).
How to interpret your Kessler-10 score
- Each item is scored from 1 = ‘none of the time’ to 5 = ‘all of the time’. Scores of the 10 items are then summed, yielding a minimum score of 10 and a maximum score of 50.
- Low scores indicate low levels of psychological distress and high scores indicate high levels of psychological distress: 10–19 = likely to be well, 20–24 = likely to have mild distress (anxiety or depression), 25–29 = likely to have moderate distress (anxiety or depression) and 30–50 = likely to have severe distress (anxiety or depression).
- Please note that while great care has been taken with the development of this self-test, it is not intended to be a substitute for professional clinical advice. The result is indicative only. If you have scored above the threshold on this scale, see your doctor or a mental health practitioner, such as a counsellor, psychotherapist or psychologist.
