Participation in cancer survivorship survey research: Differences by rurality and age

Rural cancer survivors have worse outcomes than their urban counterparts. To improve outcomes, it is essential that rural survivors participate in research, yet they are underrepresented in cancer research. The aim of this study was to assess urban-rural differences in participation in a cancer survivorship survey and differences in mode of participation (mail, online, or phone) by rurality and age.

We developed a survivorship needs assessment survey and invited cancer survivors to participate by mail, online, or phone. We compared participation between rural and urban invitees and examined differences in mode of participation by rurality and age.

A quarter (25.47%) of invited rural patients and 27.84% of invited urban patients participated in the survivorship study. The probability of participation by urban survivors was approximately 1.09 times higher than for rural survivors (χ ²(1) = 4.31, p = 0.038). Rural survivors were more likely to participate by mail (average difference [Rural-Urban] = 9.64%, p < 0.001), while urban survivors were more likely to participate online (average difference [Urban-Rural] = 8.77%, p < 0.001). As participant age increased, the likelihood of survey participation by mail increased (1.16% per year of age, p < 0.001) while the probability of participating online decreased by 1.20% per year of age (p < 0.001).

To ensure equitable access to research for rural and older cancer survivors, researchers should design studies with a range of participation modes. Non-digital methods, such as mailed paper surveys, appear to promote participation among rural and older survivors.
