For sample adults who knew of, but did not possess, special equipment for increasing their mobility (KNOWDEVICE), DIFWODEVICE reports how often respondent had "difficulties" because they did not have the special equipment.


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.

Interviewers asked, "How often do you have difficulties because you do not have this special equipment or assistive devices? (sic) Would you say always, often, sometimes, rarely, or never?"
