Background: Physical activity has numerous associated benefits for cancer survivors. Compared with their urban counterparts, rural Australians experience a health disadvantage, including poorer survival rate after diagnosis of cancer.
Objective: The aims of this study were to test the effectiveness of an online 12-week walking intervention designed for cancer survivors and explore region-specific psychological predictors of behavior change.
Methods: This was a quasi-randomized controlled trial of an online resource designed according to Social Cognitive Theory and Self-determination Theory, based on individualized goal setting. Measures of habitual walking, motivation, and self-efficacy were taken at baseline, postintervention, and 3-month follow-up in an intervention group (n = 46) and active control group (n = 45). The control group was provided a pedometer but did not have access to the online program.
Results: An increase in steps/day at 12 weeks was observed in both groups, with a larger increase in the intervention group; these increases were not sustained at the 3-month follow-up. Psychological predictors of maintained change in steps per day (motivation, barrier self-efficacy, and relapse self-efficacy) did not differ between metropolitan and rural participants. Changes in steps per day among intervention participants were predicted by changes in relapse self-efficacy and barrier self-efficacy.
Conclusions: The intervention was successful in increasing physical activity postintervention; however, changes were not maintained at follow-up. There were no region-specific predictors of engagement in the intervention.
Implications for practice: Nurses are seamlessly positioned to promote health interventions like walking. Nurses should reframe physical activity with patients so that relapse is seen as common and possibly inevitable when adopting a regular physical activity habit.
