Examining the spatial congruence between data obtained with a novel activity location questionnaire continuous GPS tracking and prompted recall surveys

摘要

BackgroundPlace and health researchers are increasingly interested in integrating individuals’ mobility and the experience they have with multiple settings in their studies. In practice, however, few tools exist which allow for rapid and accurate gathering of detailed information on the geographic location of places where people regularly undertake activities. We describe the development and validation of a new activity location questionnaire which can be useful in accounting for multiple environmental influences in large population health investigations.
