Weight is measured using a digital floor scale. The instrument should be calibrated daily using standardized weights, and a log of calibration results should be maintained. For reliability, the measurements are taken in duplicate. A third measurement should be taken if the first two measurements differ by >200 grams or 0.25 pounds. If it is necessary to take a third measurement, the two closest measurements are averaged. Should the third measurement fall equally between the first two measurements, all three should be averaged. Measured weight is recommended, and self-reported weight should only be recorded as a last resort.* Please indicate how the weight was collected (i.e., measured vs. self-reported). In instances where both self-reported and measured weight are collected, collect the self-reported weight first before measuring weight. *NOTE: Self-reported weight values are considered to be less accurate. Self-reported weight is subject to error and is used when measured weight cannot be obtained.
