For sample adults, KNOWDEVICE indicates whether the respondent knew of, but did not have, "any special equipment or assistive devices that would aid [in your] usual activities."


Interviewers prefaced the questions on special equipment by specifying that special equipment referred to hearing aids, wheelchairs, scooters, canes, prostheses, special phones, or special computer devices but not eyeglasses or false teeth. An extensive list of example devices is given in the Field Representative's Manual.

Respondents who answered affirmatively to this question were asked to quantify how much difficulty they have because of the lack of this special equipment (DIFWODEVICE).
