Description
For sample adults, SMELLDIFF reports the level of difficulty the respondent had with their sense of smell or ability to detect odors in the past 12 months. Respondents were asked whether they had no difficulty, a little difficulty, moderate difficulty, a lot of difficulty, or no sense of smell at all.
SMELLDIFF is one of several questions sponsored by the National Institute on Deafness and Other Communication Disorders (NIDCD) to gather information on smell and taste disorders in adults. For more information and a complete list of these variables, see the description for TSTSMDOC.
