You will be asked to fill out a questionnaire containing questions about your mood, coping with cancer, how closely you follow your treatment schedule, your thoughts, your demographic information (such as age and race), and your medical history. It should take between 25-35 minutes to complete the questionnaire. If you score as nondepressed on the questionnaire, you will be contacted again every week for 6 weeks during radiation treatment, to check for depression again. If you score as depressed during a later screening, you will then be asked additional questions about your symptoms, coping, and social support. It should take between 10-20 minutes to complete these additional questions.
