Monitors and self-reporting are two methods of measuring energy expended in physical activity, where monitor devices typically have much smaller error variances than do self-reports. The Physical Activity Measurement Survey was designed to compare the two procedures, using replicate observations on the same individual. The replicates permit calibrating the personal report measurement to the monitor measurement and make it possible to estimate components of the measurement error variances. Estimates of the variance components of measurement error in monitor-and self-report energy expenditure are given for females in the Physical Activity Measurement Survey.
