A Web-based Tailored Health Behavior Intervention for Breast and Colon Cancer Survivors (eWellness)

The primary objective of this study is to compare the differences in fruits and vegetable intake and physical activity from pre- to post- study between the intervention and control groups (i.e. the difference in differences). The study involves the use of web-based educational materials over a four week period. The investigators hypothesize that those in the intervention group will show a greater increase in fruit and vegetable intake and engage in more physical activity than those randomized to the control group. Eligible breast and colorectal cancer survivors from the UNC Health Registry/Cancer Survivorship Cohort (UNC HR/CSC) will be selected, consented, and randomized to either the intervention or control group. Both groups will fill out baseline surveys. The intervention group will receive a total to 4 newsletters for 4 weeks and at the beginning of week 5, they will asked to complete the follow-up survey online. The intervention newsletters focus on increasing physical activity and healthy diets. The control group will receive 4 newsletters in the same time frame as the intervention. The focus of the control group\'s newsletters will be on topics relevant to cancer survivors (e.g. getting back to work after treatment, managing finances) but will not focus on physical activity or diet. All contact with participants will take place online (i.e. surveys and newsletter delivery) from the study web site.
