You have several options for where you may choose to complete the questionnaires. They may be completed when you visit the doctor for your appointments, at home (you will have to mail them back in self-addressed stamped envelopes that will be provided to you), or over the internet. If you are interested in the internet option, please ask study staff for more details. If at any time, your healthcare provider does not think it would be in your best interest to receive a survey at one of your scheduled time points, you will not be given a survey at that time, and you will be taken off this study.
