Monitoring your progress

To save your scores use the buttons below. If your device supports local storage a copy of your scores will be saved and shown in a table and on a graph. Over time you will see how your scores change. You can delete either individual entries or all your scores in one go. Because your scores are saved locally to update your scores you will need to use the same browser (e.g. Safari, Chrome, Firefox) on the same device. It is important to remember that the security of this data is your responsibility. If this is a shared device or anyone else has access to your browser they will also be able to see your scores.


Please treat your scores on these or any other online questionnaires with caution. Questionnaires cannot be used to make a diagnosis of a mental health condition. Where a mental health condition has been diagnosed by a suitably qualified and experienced health professional these questionnaires may be used as a guide to the current severity of your condition. Always consult with a qualified health professional if you are concerned in any way about your mental health.

If you are worried about your safety, you should immediately consult with your GP or another suitably qualified health professional. If you are in the UK the following numbers might be of help to you:

  • NHS Emergencies: call 999.
  • NHS Non-emergency number: call 111.
  • Samaritans: call 116 123 or email
