Background: Most rural adults do not meet current guidelines for physical activity (PA). A 12-week feasibility study tested the effectiveness of using the 5A’s model for PA counseling on rural adults’ PA behaviors. Methods: Inactive rural adults recruited from a primary care clinic were randomized to an intervention (n = 30) or control (n = 29) group. All subjects wore a Fitbit to track steps and active minutes. The intervention group completed action plans to improve self-regulatory PA strategies and received weekly motivational text messages to improve PA behaviors. Theory of planned behavior constructs and self-regulatory strategies of planning, goal setting, and tracking (steps and active minutes) were measured with both groups. The control group received the Fitbit only. Results: All individuals became more physically active; however, no significant differences between groups in active minutes or steps were found. All subjects, regardless of group, increased steps (P > .05). There were no statistically significant differences between groups on any of the theoretical variables. Conclusions: It is vitally important to continue to find ways to make PA a priority to improve the overall health and well-being of rural adults. Future research warrants adjusting the intervention dose and strategies to increase PA that can be maintained long term.
