To date, national panel studies focused on health and aging have mostly collected subjective (self-reported) measures of visual and auditory function. The National Health and Aging Trends Study (NHATS), a study of Medicare beneficiaries ages sixty-five and older, recently developed a protocol for measuring objective visual and auditory function for its annual, in-home data collection conducted by trained interviewers. The protocol includes three vision tests\u2014distance and near acuity and contrast sensitivity\u2014and one hearing test\u2014pure-tone audiometry\u2014conducted using a tablet platform with results recorded in a scannable booklet. To identify operational issues and evaluate data quality for the proposed set of vision and hearing tests, NHATS incorporated a pilot study into its 2019 round (N\u2009=\u2009417 participants and N\u2009=\u20099 interviewers). Using these pilot study data, the objectives of this paper are to: (1) describe the NHATS protocols to collect objective measures of visual and auditory function; (2) evaluate the quality of the data collected; and (3) assess whether results are influenced by interviewers. We found that respondents were highly likely to participate, with cooperation rates for each test about 90 percent. Data were high quality, with low rates of missingness, test results significantly associated with age and self-reported items, and percentages with poor vision or hearing consistent with prior population-based studies. Objective measures were more likely than self-reports to classify participants as having visual and auditory impairments and had stronger relationships with demographic correlates. Interviewer effects were small and not statistically significant in this small sample. Results of this study have demonstrated that objective visual and auditory functioning can be successfully incorporated into an interviewer-administered home-based protocol.<\/jats:p>","DOI":"10.1093\/jssam\/smaa044","type":"journal-article","created":{"date-parts":[[2021,1,4]],"date-time":"2021-01-04T12:28:24Z","timestamp":1609763304000},"page":"309-334","source":"Crossref","is-referenced-by-count":27,"title":["Collecting
