An interventional study of Tailored messaging in Prolonged Sitting, sponsored by University of Wisconsin, Madison. Completed at 1 site in United States. Open to participants aged 40 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-02.
Sponsored by University of Wisconsin, Madison · Not applicable, Interventional, and Prevention
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:
Participants will:
University of Wisconsin, Madison is the lead sponsor of 1,161 studies on the registry; 182 are open to participants now.
Of its 151 completed or terminated interventional studies of FDA-regulated products, 114 (75%) have results posted.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
Participants who are office workers
Behavioral: Tailored messaging
Participants who are truck drivers
Behavioral: Tailored messaging
Participants receive motivational messages customized to their previously stated expectations and goals.
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.
Time frame: 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.
Time frame: 30 days
Feasibility - retention rate
Retention rate will be measured by the number of participants who complete the study.
Time frame: 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.
Time frame: 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.
Time frame: Baseline to 30 days
