The Effect of Rural Residence on Cancer-Related Self-Efficacy With UK Cancer Survivors Following Treatment

Purpose To examine rural and urban differences in cancer-related self-efficacy with UK cancer survivors following treatment. Methods A cross-sectional postal survey with posttreatment cancer survivors in the East Midlands of England. The survey collected data on demographics and cancer-related self-efficacy using the Cancer Survivors Self-Efficacy Scale. Rural-urban residence was determined using Office for National Statistics classifications. Linear Regression models were developed using a Directed Acyclic Graph that determined confounding variables. When the model deviated from normal the outcome variable was transformed using the Box-Cox transformation. Findings Of those surveyed, 227 responded, of whom 58% were female and 45% lived in a rural area. A linear regression model showed a significant increase in cancer-related self-efficacy in cancer survivors living in rural areas compared to urban residents (0.76, 95% CI: 0.25-1.27), although the residual plot deviated from a normal distribution. A model of the effect of rural living on a Box-Cox transformed outcome variable confirmed an increased cancer-related self-efficacy score in rural regions (9.06, 95% CI: 2.97-15.14). Rural living remained significant (7.98, 95% CI: 1.78-14.19) after adjustment for the respondents' income. Similarly adjusting for deprivation led to a significant increase in cancer-related self-efficacy in rural regions (8.64, 95% CI: 2.48-14.79). Conclusion This study has important implications when considering the impact of location of residence on cancer-related self-efficacy in cancer survivorship. The role of deprivation had some impact for sample respondents in both the urban and rural environment and merits further analysis.
