Objective 2: Conduct an experiment to test the clinical promise of the website The study will be conducted at 3 sites (Women's College Hospital, Princess Margaret Hospital, and Calgary Breast Health Centre), selected among the 28 sites that are participating in the CYBCC cohort study. Prior to launching the website, a baseline comparison group of 100 newly diagnosed YWBC will be recruited. They will be assessed on a number of variables, including emotional distress and self-efficacy for coping with cancer. Four months later, emotional distress and self-efficacy will be assessed again. Following completion of the website, another cohort of 100 patients will undergo the same procedure, however these participants will have the Internet website introduced to them. The two groups will then be compared to determine if access to the website reduces the traumatic stress associated with a breast cancer diagnosis and treatment, and improves coping confidence.
