In this article the authors discuss and develop a statistical model that describes the relationship between an individual's short-term recall of his or her physical activity and usual activity over a long period of time. Modeling measurement error in recall data can be used to provide more...

In this study, school children wore a validated accelerometer and completed the Previous Day Physical Activity Recall for three consecutive days. When applied to the holdout sample, an algorithm of predicted minutes of moderate to vigorous physical activity showed good agreement with the actual...
