COVID-19 is an unprecedented global public health event. As such, existing models and data sets were not applicable to garner an understanding of the experiences of older adults living through the pandemic. Efforts to respond to COVID-19 have involved stay-at-home orders and physical distancing. Of particular concern is understanding how these responses may impact the development of loneliness, isolation, and healthcare access among older adults. Recognizing the need to increase knowledge in this area, and the unpredictability of COVID-19, the Aging in the Time of COVID-19 Study was developed in April 2020. This is a multi-wave, longitudinal, North American survey-based study of older adults during COVID-19. Data collected included information on social isolation, loneliness, social support networks, health access, health status, mental health status, resilience, and COVID-19 fear, along with demographics. Participants also provided open-ended responses describing their experience of living through COVID-19. Participants have been recruited through a snowball sampling approach with an emphasis on social media as a recruitment tool. Three waves of data collection are complete (Wave 1 n = 1,483; Wave 2 n = 682, and Wave 3 n = 414) and additional waves are planned. Preliminary data analysis of the first three waves is underway. The findings aim to inform decision makers, scholars, and practitioners on the health and social care needs of older adults during a public health emergency. The data are believed to represent one of the first longitudinal social support network study of older adults during a pandemic.
