Completing this second questionnaire is completely optional, but your answers will help us understand more about ME/CFS.

If you are invited to fill in the second questionnaire, you will have already completed the first DecodeME questionnaire, and possibly also submitted a DNA sample. You are a participant in DecodeME even if you can’t finish the second questionnaire and the information you have already provided is incredibly useful to ME/CFS research.

We are extremely grateful to you and to every participant who has generously given their time and precious energy to take part in the study. Every participant matters to us, including those who may chose not to complete this second questionnaire.
