DEFINITION:
The purpose of this variable is to help determine the preinjury functional level of the Model System participant. This variable was taken from the wording of the Long Form of the 2000 Census, which asks about current function. To meet our needs, this question was revised to ask specifically about the patient's specific function prior to the TBI regarding:
a. Blindness, deafness, or a severe vision or hearing impairment, and
b. A condition that substantially limited one or more basic physical activities such as walking, climbing stairs, reaching, lifting, or carrying.
CODE:
1 No
2 Yes
6 Variable did not exist at time of data collection
9 Unknown
NOTE:
Variable was successfully pilot tested in first quarter 2005.
*Alcoholism can be considered a premorbid condition if it interfers with the person's functioning.
SOURCE:
Questions were taken from the long form of the 2000 census and modified to ask about premorbid function instead of current level of function. (Developed by a group headed by Flora Hammond.)
EXAMPLE:
Participant is an amputee with no other physical impairments.
a. 1
b. 2
