Reactions to Disease Risk Information

This study is part of an effort to learn about interactions between doctors and patients. The study will use virtual reality technology to examine how patients and doctors interact when they discuss disease risks. Men and women between the ages of 25 and 40 who have access to the Internet and were born and raised in the United States may be eligible for this study. Participants will be recruited from the Washington D.C. area. Participants undergo the following procedures: * Complete an online questionnaire about their health-related background, family health history, cancer risk perceptions, and demographic information (e.g., age, marital status, education, etc.). * Participate in activities in a virtual reality environment in which they interact with a virtual doctor in a virtual clinical scenario. For this experiment, participants wear a head-mounted display that allows them to see the virtual world images. * Fill out a second questionnaire after completing the virtual reality activities. This questionnaire includes information on the participants virtual reality experience, the information provided in the experience, and questions about themselves and their background.
