Design and evaluation of a computer-based 24-Hour physical activity recall (cpar24) instrument.

Background: Widespread access to the Internet and an increasing number of Internet users offers the opportunity of using Web-based recalls to collect detailed physical activity data in epidemiologic studies. Objective: The aim of this investigation was to evaluate the validity and reliability of a computer-based 24-hour physical activity recall (cpar24) instrument with respect to the recalled 24-h period. Methods: A random sample of 67 German residents aged 22 to 70 years was instructed to wear an ActiGraph GT3X+ accelerometer for 3 days. Accelerometer counts per min were used to classify activities as sedentary ( Results: As compared with accelerometry, the cpar24 underestimated light activity by −123 min (median difference, P difference Conclusion: These data show that the cpar24 is a valid and reproducible Web-based measure of physical activity in adults. |
