Interview questions.

Theory of SDM (adapted from [17])	Interview questions
Recognition of the decision	Can you remember when you were told about having dialysis or not? Can you remember how you felt?
Knowledge transfer and exchange	Were you given any information? How far did you understand all the information you were given?
Expression of values and preferences	How much input did the doctors and/or nurses have in making the decision? How far do you think the decision was shared between you and your family?
Deliberation	Were you given an opportunity to think about the information? Was anyone with you to help explain the information? Did you try and find out anything more yourself?
Implementation of the decision	Did you feel supported in making your choice? Did you feel your own views were taken into account? Do you feel you made the right decision? Do you have any suggestions for improving the process?
