Codes and Frequencies
For all sample adults, BALPLENS indicates had difficulty walking wearing glasses in the last 12 months. The questionnaire included the instructions, "Do not include times when drinking alcohol." The interviewers were also instructed to mark "No" if the respondent experienced this problem "for reasons OTHER than dizziness or balance. Examples include respondents who are in a wheelchair, are deaf, blind, don't have a driver's license, etc."
In 2008, the question for this variable was part of the Sample Adult Balance Supplement, sponsored by the National Institute on Deafness and Other Communication Disorders.
The supplement consisted of a total 205 questions (some of which were only asked based on a previous response). A summary of the topics included in the supplement is provided under BALDIZYR
