The specific aims of this exploratory study, which is a collaborative effort between investigators at the University of North Carolina, the University of Wisconsin, and the M. D. Anderson Cancer Center (MDACC), are as follows:
Primary Aim: To determine whether stage I-III colon cancer survivors who are randomized to Survivorship CHESS (a Comprehensive Health Enhancement Support System (CHESS) or smart phone intervention aimed at promoting increased physical activity), as compared to those who are assigned to usual care, demonstrate significantly greater increases in levels of physical activity from baseline to completion of the intervention (6 M (month) follow-up).
Secondary Aims:- To examine whether stage I-III colon cancer survivors who are randomized to Survivorship CHESS, as compared to those who are assigned to usual care, demonstrate significantly greater durability in physical activity long-term, e.g., from baseline to 9 M follow-up (3 M after the intervention period is complete).
- To examine whether stage I-III colon cancer survivors who are randomized to Survivorship CHESS, as compared to those who are assigned to usual care, demonstrate significant improvements in secondary outcomes, such as improved weight status (healthy range for body mass index or BMI is >18.5 to <24.9), decreased distress, and improved quality of life.
- To examine associations between various moderators (gender, age, socio-economic status, cancer stage and treatment, and comorbidity) and intervention efficacy to increase physical activity.
- To examine associations between various mediators (Survivorship CHESS use, autonomy, competence, and relatedness) and intervention efficacy to increase physical activity.
