7.1.0.4 Details

Interviewers should read the following introduction prior to administering the GAD: “Over the LAST 2 WEEKS, how often have you been bothered by the following problems?”

If either of the first 2 questions are coded either ‘1 - Several Days’, ‘2 - More Than Half Of The Days’, or ‘3 - Nearly Every Day’, then proceed to ask the remaining GAD items.

If both of the first 2 questions are coded ‘0 - Not at all’, code remaining GAD items as ‘81 - Not Applicable’ and skip to next section of interview.

The GAD should not be administered to a significant other, or any other proxy. If the individual is unable to provide data, use code ‘82. Not Applicable: No data from person with TBI’.

Every effort should be made to obtain the GAD assessment, however, if any items can not be assessed, use code ‘99. Unknown’. Do not leave blanks.

Participant responses to these variables may be affected by the COVID-19 pandemic starting in March of 2020.

7.3.0.7 Characteristics

In 2003, the TBIMS had difficulty obtaining this information (11% missing data). Five Model Systems had missing data rates of 10% or more. Data managers report that missing data are due to some persons with TBI being unable to provide information for the Form II, combined with the requirement that the SWLS must not be answered by anyone other than the person with TBI. A new code was been added to this item to identify these cases.

Participant responses to these variables may be affected by the COVID-19 pandemic starting in March of 2020.
