Brief summary

The investigators are interested in using personalized, self-motivating messages to motivate people to exercise more.

Detailed description

The investigators are interested in using personalized, self-motivating messages to motivate people to exercise more. Through a partnership with a university, the investigators are running a large-scale, randomized field controlled trial aimed at increasing exercise frequencies during a 100-day challenge. The primary purpose of this study is to test whether sending people motivating messages they wrote to themselves in the past can keep them engaged in the challenge and motivate them to exercise more frequently. One week into the challenge, employees who have signed up for the challenge will receive an email inviting them to participate in a short activity. Employees who click on the link will be directed to a survey. Once they finish reading the first introductory page and click next, they will be randomly assigned to one of two groups. In the control group, employees will be encouraged to write down what they think will motivate them to walk more after 20, 50, and 90 days into the Challenge. These employees will receive standard reminders on the 20th, 50th, and 90th day of the challenge. In the treatment group, employees will be encouraged to write down motivating messages that they will receive on the 20th, 50th, and 90th day of the Challenge. All employees who are exposed to either the control or the treatment condition will be included in the analysis. The investigators plan to explore moderators based on (a) employees' demographics (age, gender, ethnicity, position), (b) employees' participation in previous challenges, and (c) employees' health condition and fitness level prior to the challenge (such as how actively they have been participating in other wellness activities, their health statistics).

Design outcomes

Primary

MeasureTime frameDescription
Activity LevelThrough study completion, 100 daysNumber of steps taken each day, as recorded in participants' online portal.

Secondary

MeasureTime frameDescription
Body Mass Index (BMI)After the 100-day challenge endsMost recent BMI in pounds (weight) and inches (height) as entered by participant, an expected average of 2 months after study start. Obtaining the data is dependent on the ability to obtain the data from the online portal.
CholesterolAfter the 100-day challenge endsMost recent total, low, and high cholesterol levels in mg/dl as entered by participant, an expected average of 2 months after study start. Obtaining the data is dependent on the ability to obtain the data from the online portal.
Blood PressureAfter the 100-day challenge endsMost recent systolic and diastolic levels in mmHg as entered by participant, an expected average of 2 months after study start. Obtaining the data is dependent on the ability to obtain the data from the online portal.
StressAfter the 100-day challenge endsMost recent self-reported stress level on a 1-5 scale (with 1 indicating Relaxed and 5 indicating Highly Stressed) as entered by participant, an expected average of 2 months after study start. Obtaining the data is dependent on the ability to obtain the data from the online portal.
