Abstract
Background: Social and structural determinants of health (SSDoH) must be measured
longitudinally in order to better understand the effects of lived experiences on the
trajectories of Alzheimer’s disease and related dementias (ADRD) outcomes. We
repeated administration of an SSDOH survey to examine response rates and response
consistency in a sample of cognitively typical older adults.
Method: One online survey and one follow-up survey were administered to cognitively
unimpaired participants (n =135) in the UPenn Alzheimer’s Disease Research Center
clinical cohort ∼1.5 years apart. The ∼225 items covered the following categories: (1)
Education, (2) Economic Status and Strain, (3) Occupation, (4) Stressors and Subjective
Stress, (6) Subjective Social Support and Status, and (7) Sociodemographic data,
which included age, race, language, disability, neighborhood, sex, sexual orientation,
and gender identity questions. We summarize pilot data on item and instrument
completion rates and changes in participant responses.
Result: 81 of 135 participants completed the follow-up survey, which is a response
rate of 60%. Most participants completed most items. The two measures with the
lowest completion rates were: Calgary Charter on Health Literacy Scale (74/81)
and the Perceived Stress Scale (69/81). Some participants who did not complete a
given measure during the first administration did complete that measure during the
second. In addition, responses on most measures, single items or multi-item scales,
varied between the administrations. Some responses appeared to change because of
ambiguity in the item’s phrasing, administration process, or reflected changes over
time in the constructs being assessed.
Conclusion: Overall, it was feasible to repeatedly administer a survey of SSDoH items
to a group of cognitively unimpaired older adults. The response rate was reasonable

but lower than expected in a group of volunteer research participants indicating
that multiple modes of administration may be useful for increasing engagement.
Differences in the data produced from repeated administration of measures was useful
in identifying ambiguity in items and methods that aid in improving research rigor
and reproducibility. The data are also useful in understanding the temporal stability or
instability of SSDOH experiences among these research participants.
