What is the study about?
The study is a quantitative observational study based on questionnaire data and accelerometer measurements. In total, 163,133 adults from Moving Denmark are included, of whom 1,525 provided accelerometer data, along with 829 non-respondents interviewed by telephone.
The study examines selection bias and the Hawthorne effect in physical activity measurement by comparing self-reported activity across four different samples.
Main conclusions:
- Participants who accept device-based measurement are more self-reported physically active than the general population (selection bias).
- Signs of a Hawthorne effect are observed, with physical activity increasing markedly during the monitoring week.
- Device-based measurements challenge representativeness in population-based physical activity surveillance.
