Comparison of calibrations (severity parameter estimates) of child items in the Isfahan Food Security Survey versus the U.S. Current Population Survey Food Security supplement. Note: For this comparison, the calibrations of the items estimated from the U.S. CPS-FSS data were adjusted by a linear transformation to equate the mean and standard deviation of the item calibrations to those estimated from the Isfahan data.
