NCT07475130

Brief 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. 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

Outcome Measures

Primary Outcomes (5)

  • 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.

    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.

    30 days

  • Feasibility - retention rate

    Retention rate will be measured by the number of participants who complete the study.

    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.

    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.
