Dear participant,

Thank you for taking part in this experiment. You will be asked some questions concerning yourself, your family and the way you experience pain.

It is very important that you do the task by yourself, without any help and any interference from anyone. This is because we are interested in how you describe your family and your painful experience, even if there are grammar and spelling mistakes.

Since this might be quite a laborious task, we suggest you take some time (even some days) to think about it and to draft your thoughts.

Remember: this must be your original work!

Once you are happy with what you wrote, you can copy it into the online survey. We recommend writing your drafts on your computer using a word processor (for example Microsoft Word) as the program will be able to keep count of the number of words you typed in.

We would like to remind you that your answers and all the material you decide to share will be anonymous and that you can withdraw from the study at any time.
