It should take the participant about 30 minutes to complete the questionnaires. Some of the questions on these questionnaires are personal - the participant can refuse to answer these if the participant wishes. The information the participant provides is for research purposes only and will remain strictly confidential. The individuals (e.g. doctors, nurses, etc.) directly involved in the participant's care will not usually see their responses to these questions—if the participant wishes them to know this information please bring it to their attention.
