Disability Questions Tests 2010 Weights for Sample Adult Analyses
When the Disability Questions Tests 2010 File was initially released in June 2011, the weight WTFA_DIS was provided in the file. This weight was designed to produce annual-level estimates calculated based on data included in that file. This weight should also be used for analyses combining data from the Disability Questions Tests 2010 and 2010 Person files.
Following the release in June 2011, the weight WTFA_SAD was produced. This weight was designed to produce annual-level estimates for analyses combining data from the Disability Questions Tests 2010 and 2010 Sample Adult files. The SAS program SAM_DISB.SAS creates a SAS file from the 2010 Sample Adult ASCII file merged with the Disability Questions Tests 2010 ASCII file, and then appends the weight WTFA_SAD. Additional instructions for merging NHIS files can be found in Appendix VI of the 2010 NHIS Survey Description document.
Below is a link to the data file sad_wgts.dat that contains the weight WTFA_SAD. The record layout is: HHX 1-6 FMX 7-8 FPX 9-10 WTFA_SAD 11-16.
