SurvivorCHESS to increase physical activity in colon cancer survivors: can we get them moving?

This randomized controlled trial evaluated the impact of survivorchess, an ehealth intervention, on physical activity in colon cancer survivors and to explore the impact of survivorchess on quality of life and distress. this was a two-arm single-blinded multi-site randomized controlled trial comparing a control group to an intervention group receiving a smartphone with the survivorchess program. participants using survivorchess (n = 144) increased their moderate to vigorous physical activities from 19.4 min at baseline to 50 min compared to the control group (n = 140) increasing from 15.5 to 40.3 min at 6 months (p = .083) but was not sustained 3 months after the study ended. no significant differences were found between groups over time for quality of life or distress items. reports of physical symptoms were greater than other categories for distress items. patients who had a higher body mass index and number of comorbid conditions were less likely to increase their physical activity. self-determination theory including autonomous motivation and relatedness was not associated with the outcomes. physical activity did increase over time in both groups and was not significantly different with the use of the ehealth intervention, survivorchess, compared to the control group. the amount of survivorchess use was not associated with physical activity. increasing physical activity in colon cancer survivors has the potential to improve quality of life and reduce recurrences. using smartphone-tracking devices be useful in helping to change this health behavior.
