A study testing Tailored messaging in people with Prolonged Sitting, run by University of Wisconsin, Madison at 1 site in United States.
Trial summary
This study aims to see if a new approach called "Exercise Forecasting" can help people with jobs with a lot of sitting get more active. It also tests if using this method in personal motivational messages makes it easier for them to exercise. Read more about this study

About this study
This study aims to see if a new approach called "Exercise Forecasting" can help people with jobs with a lot of sitting get more active. It also tests if using this method in personal motivational messages makes it easier for them to exercise.
The main questions it aims to answer are:
- Can "Exercise Forecasting" be used effectively for people in jobs requiring long periods of sitting?
- Do these tailored, proactive messages encourage people to exercise more and sit less?
Participants will:
- Wear the provided smartwatch and answer two questions per day
- Receive customized motivational messages
- Conditions
- Prolonged Sitting
- Being tested
- Tailored messaging
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Tailored messagingBehavioural
Participants receive motivational messages customized to their previously stated expectations and goals.
| Study group | Role | What they receive |
|---|---|---|
| Office workers | Experimental | Participants who are office workers Receives: Behavioral: Tailored messaging |
| Truck drivers | Experimental | Participants who are truck drivers Receives: Behavioral: Tailored messaging |
What is being measured
The primary outcome is the main question the study is designed to answer.
Correlation between biometric data and self-reported exercise
Biometric data will be collected through the smartwatch. Participants are also asked to self-report what type of exercise they did. These will be correlated to learn whether probability of daily activity can be predicted.
Measured: 20 days
Acceptability of customized messages
Acceptability will be qualitatively evaluated using one-on-one interviews, with semi-structured interview guides. Acceptability will be analyzed using thematic analyses.
Measured: 30 days
Feasibility - retention rate
Retention rate will be measured by the number of participants who complete the study.
Measured: 30 days
Change in level of physical activity when receiving custom motivational messages
Using data collected from the smartwatch, level of physical activity will be compared between pre-motivational messaging and post-motivational messaging.
Measured: Baseline to 30 days
Change in System Usability Scale (SUS) Score
SUS is a 10-item questionnaire about system usability. It is scored on a 5-point Likert scale, where 1 = strongly disagree and 5 = strongly agree. Scores range from 0-100 (due to reverse scoring and 2.5 multiplication). Higher scores indicate greater usability.
Measured: Baseline to 30 days
