Graphs depicting individual-level differential item functioning impact (from lordif) comparing non-Hispanic Blacks (NHB) and non-Hispanic Whites (NHW)
Individual Impact (Theta estimates by group before and after accounting for DIF and median differences before and after DIF adjustment (fixing and freeing parameters based on DIF)
*Dotted line is the mean difference between the initial and DIF-adjusted theta estimates (lordif depression NHB vs NHW)
