Summary
Theory-based interventions using text message reminders effectively increased brisk walking in sedentary individuals. Goal reminders also aided weight loss, demonstrating the potential of SMS for enhancing health behavior change.
Area of Science:
- Behavioral science
- Public health interventions
- Digital health
Background:
- Sedentary lifestyles pose significant health risks.
- Theory-based interventions are crucial for promoting physical activity.
- Text message reminders offer a scalable approach to behavior change.
Purpose of the Study:
- To evaluate two theory-based interventions for promoting brisk walking.
- To assess the impact of implementation intentions and text message (Short Message Service; SMS) reminders.
- To compare SMS plan reminders versus SMS goal reminders.
Main Methods:
- 149 participants randomized into three groups: implementation intention + SMS plan reminder, implementation intention + SMS goal reminder, and control.
- Baseline and 4-week follow-up assessments.
- Validated self-report measures for physical activity, implementation intention, goal recall, weight, and waist-to-hip ratio.
Main Results:
- Both intervention groups significantly increased brisk walking compared to the control group.
- No reduction in other physical activities was observed.
- The SMS goal reminder group showed the greatest weight loss.
- SMS plan reminders improved plan recall, while SMS goal reminders enhanced goal recall.
Conclusions:
- Theory-based interventions incorporating SMS reminders are effective in promoting brisk walking among sedentary populations.
- Text messages can enhance the recall of implementation intentions and goals.
- These interventions show promise for improving physical activity and weight management.
