Do I have to take part in this survey?

Can my (wife, husband, child, legal guardian, etc.) answer these questions for me?

Because you were chosen at random to participate in this important study, and because you are the one receiving dialysis care, no other person can take your place. However, you may skip or refuse to answer any question you are uncomfortable with or do not know the answer to. Someone else may assist you with reading, writing, or translation, but only you may provide answers to the survey.
