Throughout the study, you will be asked to complete the symptom questionnaire. You will be asked about symptoms from therapy you may be experiencing and how they may be interfering with your daily activities. The study staff will either meet you during your regular clinic visit or call you at your home at a time that is convenient for you. In the clinic, you will complete the questionnaire by paper and pen, or by entering your answers into an electronic tablet computer. On the phone, study staff will ask you the questions and record your answers on paper or enter them into a computer. The symptom questionnaire will take up to 5 minutes to complete.
