Abstract
Purpose The COVID-19 pandemic, beginning in early 2020, has resulted in massive social, economic, political and public health upheaval around the world. We established a national longitudinal cohort study, the COVID-19 Coping Study, to investigate the effects of pandemic-related stressors and changes in life circumstances on mental health and well-being among middle-aged and older adults in the USA.
Participants From 2 April to 31 May 2020, 6938 adults aged ≥55 years were recruited from all 50 US states, the District of Columbia and Puerto Rico using online, multi-frame non-probability-based sampling.
Findings to date Mean age of the baseline sample was 67.3 years (SD: 7.9 years) and 64% were women. Two in three adults reported leaving home only for essential purposes in the past week (population-weighted proportion: 69%; 95% CI: 68% to 71%). Nearly one in five workers aged 55–64 years was placed on a leave of absence or furloughed since the start of the pandemic (17%; 95% CI: 14% to 20%), compared with one in three workers aged ≥75 years (31%; 95% CI: 21% to 44%). Nearly one-third of adults screened positive for each of depression (32%; 95% CI: 30% to 34%), anxiety (29%; 28% to 31%) and loneliness (29%; 95% CI: 27% to 31%), with decreasing prevalence of each with increasing age.
Future plans Monthly and annual follow-ups of the COVID-19 Coping Study cohort will assess longitudinal changes to mental health, cognitive health and well-being in relation to social, behavioural, economic and other COVID-19-related changes to life circumstances. Quantitative and in-depth qualitative interview data will be collected through online questionnaires and telephone interviews. Cohort data will be archived for public use.

Strengths and limitations of this study
Large sample size of US adults aged ≥55 years with representation from all 50 US states, the District of Columbia and Puerto Rico.
Longitudinal design with repeated measures of depression, anxiety, loneliness, cognitive health and health behavioural outcomes, allowing the investigation of rapid change over time in these outcomes in relation to COVID-19-related social and economic exposures.
The internet-based, non-probability sampling design allowed us to rapidly enrol a large cohort during the early months of a major pandemic, but led to under-representation of certain sociodemographic groups and non-internet users.
The mixed methods approach provides in-depth qualitative data that add nuance and detail to the epidemiological findings, and which may inform the development of future hypotheses.
Introduction
The COVID-19 pandemic has dire immediate and long-term consequences for population health and well-being. Many middle-aged and older adults are not only at elevated risk for severe morbidity and mortality from COVID-19, but may also be vulnerable to psychological, social and economic harms associated with the pandemic.1–3 Physical distancing, a necessary intervention to reduce transmission in the absence of a vaccine, was enacted through shelter-in-place orders and social distancing recommendations across most of the USA beginning in mid-March 2020.4 At the same time, a deep economic recession took hold, with a 9.2% increase in unemployment recorded by the end of May 2020.5 Older adults became a key population group of concern during this time, with the highest rates of COVID-19 morbidity and mortality identified among those aged ≥65 years.6 Subsequent political and popular media discourse has depicted ‘the elderly’ as frail, burdensome and disposable.7
The potentially complex mental health effects of social and economic upheaval during the COVID-19 pandemic are unknown among middle-to-older aged US adults, who experience heterogeneous COVID-19 risk statuses.8 While there is relatively little literature on this topic, self-isolation and quarantine during the SARS and Middle East respiratory syndrome pandemics were associated with adverse mental health outcomes.9 10 These pandemics were short-lived and less severe in scale than COVID-19, with minimal impact in the USA. Emerging evidence indicates elevated prevalence of depression, anxiety and loneliness in younger adults during the COVID-19 pandemic in the USA,11–14 yet evidence among middle-aged and older adults remains sparse.15 Pre-pandemic evidence indicates that social isolation, negative financial shocks and stress have adverse effects on mental health, cognitive function and well-being among middle-aged and older adults.16–21 The specific forms of these exposures during COVID-19 warrant investigation in order to understand the medium-term and long-term effects of the pandemic on middle-aged and older adults’ health.
A key form of life disruption due to COVID-19 is the need for physical isolation. Older adults may need to isolate more intensely and for longer than younger groups in order minimise COVID-19 morbidity and mortality in the population, in addition to middle-aged adults approaching age 65 years who experience comorbid conditions or other ageing-related conditions that may place them at elevated risk.8 22 This population group may thus experience prolonged periods of physical isolation that health systems, communities and personal social support networks need to be equipped to handle.3 However, the current lack of evidence on modifiable factors to support middle-aged and older adults’ health and well-being during the COVID-19 pandemic limits the development of targeted, equitable public health strategies to support their short- and long-term health outcomes in the wake of this crisis.
Objectives
We launched the COVID-19 Coping Study in order to investigate how social and economic changes due to the COVID-19 pandemic impact mental health and well-being of US adults aged 55 years and over. Primary outcomes of interest are depressive symptoms, anxiety symptoms and loneliness. Secondary outcomes are self-rated health, self-rated memory and cognitive health, and life satisfaction. Measures of the primary and secondary outcomes are included at baseline and each study follow-up, in order to assess their associations with social and economic risk and resilience factors of interest cross-sectionally at baseline and longitudinally over time as the pandemic progresses. Risk and resilience factors of interest include: physical isolation and forms of face-to-face and virtual social engagement; changes to living circumstances and household composition; changes to employment and income, especially for those adults approaching and working beyond retirement age; COVID-19 incidence, hospitalisation and mortality among family and friends; coping strategies and changes in lifestyle behaviours; and neighbourhood contextual factors including access to parks and green space, residential segregation and economic affluence and disadvantage. We selected these factors as those which may be most impacted by the pandemic, and which have prior evidence for their relationships with mental health, cognitive health and well-being among adults in the study age range.16–21 The study thus aims to provide data to inform public health strategies to support middle-aged and older adults during and beyond the pandemic. The objective of this cohort profile is to describe the cohort design, recruitment, data collection procedures, measures, and early baseline findings.
Cohort description
Design
We employed a parallel convergent mixed-methods design in a nationwide longitudinal cohort study, through the collection of quantitative and qualitative data in online surveys and telephone interviews (figure 1).23 Eligible participants were adults aged ≥55 years who resided in the USA, including Puerto Rico, and who were able to access and complete the online survey in English or Spanish.
Parallel convergent mixed-methods design.
Recruitment strategy
We used a multi-frame, non-probability online recruitment strategy to enhance coverage of diverse populations and geographic locations. The first sampling frame was the ‘snowball sample’, which was recruited through social media including Facebook and Instagram distribution and advertisements, organisational mailing lists, the NIH ResearchMatch database, the University of Michigan Health Research database and word-of-mouth snowball sampling in English and Spanish. Because some older adults may be harder to recruit online and through social media, snowball sampling was a key aspect of our recruitment strategy.24 25 We encouraged study participants to recruit others through word-of-mouth, and we promoted the study to prospective participants as a way of understanding how middle-aged and older adults are coping with the COVID-19 pandemic. The second was the ‘panel sample’, which was recruited from an online research panel maintained by the professional survey company Dynata (formerly known as Survey Sampling International). We implemented sampling quotas for age, gender, race, ethnicity and education that matched the general US population aged ≥55 years based on the Centers for Disease Control and Prevention’s Wide-ranging Online Data for Epidemiologic Research (CDC WONDER).26 27 The snowball sample participants did not receive compensation, while panel sample participants received a nominal amount of approximately US$1, due to commercial arrangement with the company that maintained the sample. Additional details on recruitment can be found in the online supplemental material.
Supplemental material
Data collection
Baseline data were collected through a questionnaire designed to take approximately 17 min on computer, tablet or smartphone interfaces, administered through the University of Michigan Qualtrics. Participants were given 1 week to complete the questionnaire after starting it. The baseline questionnaire was developed in consultation with survey methodologists at the Survey Research Center at the University of Michigan Institute for Social Research. All study participants provided online informed consent before beginning the questionnaire (see online supplemental material for information sheet and consent form). Participants in the snowball sampling frame were invited to provide their email addresses if they consented to be contacted for follow-ups. Participants will be invited via email to complete brief follow-up questionnaires monthly for 1 year, and annually for 5 years. In Spring 2021, 100 snowball sample participants will be randomly sampled within sociodemographic strata to approximately match general population aged ≥55 years, and invited to complete 45-minute, semi-structured in-depth interviews by telephone or secure video call.
Measures
Baseline online questionnaire
The baseline questionnaire collected data on sociodemographic factors, personal COVID-19 testing and symptom history, social network burden of COVID-19 morbidity and mortality (family and friends with symptoms, positive tests, hospitalisation and death due to COVID-19), worry about COVID-19, attitudes towards governmental responses to COVID-19, self-isolation, frequency and types of contacts with family members and friends, changes in daily behaviours, social media use, use of mobility aids, housing conditions and residence zip code (see online supplemental material for full questionnaire). Racial and ethnic group categories were defined according to US Census definitions.28 They are presented in this report according to categories of racialised identity, whereby those who identified as multiple races were grouped to a single racial–ethnic category based on the social processes of US racialisation and heightened racial sensitivity and hostility amid the COVID-19 pandemic.29–31 We collected baseline data on the following primary and secondary outcomes: depressive symptoms (8-item Center for Epidemiological Studies Depression Scale; CES-D), anxiety symptoms (5-item Beck Anxiety Inventory; BAI), loneliness (3-item UCLA Loneliness Scale), life satisfaction (scale of 0 through 10, from the Gallup World Poll) and self-rated general health and self-rated memory (both 5-point Likert-type scales).32–34
Self-reported pre-COVID-19 covariates were as follows: employment status, job industry according to the 2018 Standard Occupational Classification from the U.S. Bureau of Labor Statistics, smoking status, alcohol consumption, moderate-to-vigorous physical activity, physician-diagnosed health conditions, degree of social isolation (using the 5-point social isolation index from the English Longitudinal Study of Ageing35), usual mode of transportation and usual household co-habitants. Open-ended qualitative questionnaire measures inquired about strategies that respondents were taking to help them cope with the COVID-19 pandemic, and any other experiences during the COVID-19 pandemic that they wanted to share.
Follow-up online questionnaires
The content of the follow-up questionnaires varies month-to-month, as certain items are rotated and the content is informed by emergent themes in participant responses to previous questionnaires and developments in the COVID-19 pandemic (online supplemental table 1). All monthly and annual follow-up questionnaires will include the primary and secondary study outcomes.32–34 The Patient-Reported Outcomes Measurement Information System Applied Cognition (General Concerns and Abilities) 6-item scales are included at the 4-month follow-up and all subsequent even-numbered monthly follow-ups.36 The question rotations are intended to reduce questionnaire length and repetitiveness for the participants, as an effort to minimise attrition. The follow-up questionnaires are available as they are fielded (https://sph.umich.edu/covid19copingstudy/).
Follow-up in-depth interviews
The in-depth interviews will aim to deepen understanding of participants’ experiences and perspectives during the COVID-19 pandemic. Semi-structured questions in telephone or secure video calls will probe about secondary health outcomes related to the social, behavioural and economic impacts of COVID-19. We will ask about altered daily routines, social engagement, service provision and the neighbourhood environment. Questions will also probe for psychosocial strengths, coping strategies and community resources used to cope with adversity during the pandemic. In addition to audio and/or visual recordings, interviewers will record notes during and after the interview. The post-interview field note guide will track progress (eg, duration, any interruptions or technical problems) and describe interviewer impressions (eg, discomfort with certain topics, emotional responses), non-verbal behaviour (eg, tone of voice, facial expression) and preliminary analysis (eg, interviewer’s questions, emerging patterns and insights).37
Population weights
Given the non-probability nature of this sample, we developed population weights to reduce potential selection and other non-sampling biases, such as coverage and non-response.38 39 The sample data were calibrated to population totals estimated by the 2018 American Community Survey 1-year estimates with respect to selected sociodemographic dimensions.40 To maximise potential bias reduction and improve SEs, these dimensions were selected by analysing which main effects and interactions were most predictive of the primary study outcomes (depression, anxiety and loneliness) in a multiple logistic regression model.39 This analysis identified that the main effects of age group (55–59 years; 60–64 years; 65–69 years; 70–74 years; 75–79 years; 80–84 years; 85+ years), education (less than high school; high school diploma or equivalency; some college or 2-year associate’s degree; 4-year college or university degree; postgraduate or professional degree), race/ethnicity (non-Hispanic: white; non-Hispanic black; non-Hispanic: Asian; non-Hispanic: other races; Hispanic: white; Hispanic: other races), Census division (New England; Middle Atlantic; East North Central—Michigan; East North Central—others; West North Central; South Atlantic; East South Central; West South Central; Mountain; Pacific) and the interaction between sex (female; male) and marital status (single, never married; single, divorced/separated; single, widowed; married or in a relationship) would accomplish the goals of selection bias reduction through population weighting. The East North Central census division was subdivided into the state of Michigan and other states, given the over-representation of Michigan due to the recruitment in the snowball sample. Missing values on sex, marital status and census division were imputed through multivariate imputation by chained equations, implemented in the mice package in R, using age group, sex, education and race/ethnicity as covariates.41 The calibration was conducted using a raking procedure over the selected dimensions listed above, using the rake function of the survey package in R.38 42–44 Three sets of weights were created: one for the overall study sample (‘snowball’ + ‘panel’), one for the snowball sample and one for the panel sample. After evaluating the distribution of the weights, the weights for the snowball sample were trimmed at the top third percentile.
Participant and patient involvement
The study participants and the public did not take part in the study design or choice of baseline questionnaire measures. However, word-of-mouth snowball recruitment was a key recruitment strategy, as we aimed to maximise inclusion of those who may not have originally seen the study through social media or the other online sources where we ‘seeded’ the study distribution.24 25 The study participants were thus deeply involved in the recruitment and conduct of the study. We have used direct participant email communication and emergent themes from analysing the qualitative open-ended responses at early time points to inform the selection of measures for the subsequent follow-ups. We are disseminating early study results to participants in monthly newsletters, and inviting responses and suggestions via email. Participant responses to the results shown in our newsletters have included sentiments about the pandemic, altered daily life and concurrent social, economic and political events, and have informed our follow-up measures.
Statistical analyses
We described the baseline characteristics of the COVID-19 Coping Study sample using basic descriptive statistics, overall and according to sampling frame, with and without population weights applied. We estimated the population-weighted distributions of self-reported effects of the COVID-19 pandemic on aspects of daily life and employment, mental health outcomes (depression; anxiety; loneliness), overall and by age group (55–64 years, 65–74 years and 75+ years). The map of participant responses was created using ArcGIS Online (Redlands, California, USA), and all other statistical analyses were conducted using Stata/SE V.16.0 (College Station, Texas, USA) and R V.4.0.0 (Vienna, Austria).
Results
Sample characteristics
A total of 4453 participants were recruited in the snowball sampling frame from 2 April to 31 May 2020, with 4401 questionnaires completed in English and 52 in Spanish. A total of 2485 were recruited in the panel sampling frame from 17 April to 15 May 2020, for a total of 6938 participants (figure 2). The majority of snowball sample participants provided their email address for follow-ups (95%; 4211/4453). Participants resided in all 50 US states, the District of Columbia and Puerto Rico (figure 3). The median questionnaire completion time was 16.3 min (IQR: 12.5–22.0 min). Mean age of the baseline sample was 67.3 years (SD: 7.9; range: 55–110), 64% were women (4437/6938), 84% were non-Hispanic white (5858/6938), 6% were non-Hispanic black or African American (383/6938), 5% were Hispanic or Latinx (349/6938), 2% were East Asian, Native Hawaiian or another Pacific Islander (165/6938) and 3% were of another racial or ethnicity minority group (183/6938; table 1). Half of respondents were retired (3598/6933; 52%), one-quarter lived alone (1799/6880; 26%), nearly half owned their home outright (3239/6938; 47%), 1 in 10 used a mobility aid (578/6778; 9%) and over half reported at least one diagnosed chronic health condition (table 1). Within the snowball sample, participant characteristics were similar across recruitment sources (online supplemental table 2). Missing data were rare, with <5% of observations missing for all variables and ≤2% observations missing for key sociodemographic and primary outcome variables (table 1).

Table 2 describes the overall and age-specific population-weighted self-reported impacts of COVID-19 on daily life and employment. The corresponding unweighted distributions are shown in online supplemental table 3. The majority of respondents were ‘moderately’ or ‘extremely’ worried about the COVID-19 pandemic (table 2). Less than 1% reported testing positive for COVID-19, while 8% of those aged 55–64 years (95% CI: 7% to 10%), 8% of those aged 65–74 years (95% CI: 7% to 10%) and 3% of those aged 75+ years (95% CI: 2% to 4%) reported recently having COVID-19-like symptoms (table 2). Respondents’ social network burdens of COVID-19 infection and mortality were higher in the younger age groups, with approximately twice as many people in the 55–64 years age group as in the 75+ years age group reporting having friends or family with COVID-19 symptoms, a positive test, hospitalisation or mortality (table 2). Among those who were working prior to the COVID-19 pandemic, the reported effects of the pandemic on employment were strongly graded by age (table 2). Approximately two in three adults across all age groups reported leaving their home only for essential purposes every day in the past week, with minimal age differences (table 2).

The baseline prevalence of depression, anxiety and loneliness was strongly graded by age (figure 4). The prevalence of depression declined from 41% in the 55–64 years age group (95% CI: 38% to 44%) to 20% in the 75+ years age group (95% CI: 17% to 23%). Anxiety prevalence declined from 36% of those aged 55–64 years (95% CI: 33% to 38%) to 19% of those aged 75+ years (95% CI: 16% to 23%). The prevalence of ‘high’ loneliness declined from 35% of those aged 55–64 years (95% CI: 33% to 38%) to 20% of those aged 75+ years (95% CI: 17% to 24%). All three scales had good internal consistency, with Chronbach’s alpha of 0.82 for the 8-item CES-D (depression), 0.75 for the 5-item BAI (anxiety), and 0.77 for the 3-item UCLA loneliness scale.
Population-weighted prevalence of depression (8-item Center for Epidemiological Studies Depression Scale score ≥3), anxiety (5-item Beck Anxiety Inventory Scale score ≥10) and loneliness (3-item UCLA Loneliness Scale score ≥6), by age group. Error bars represent 95% CIs. Differences between age groups are statistically significant at p<0.05 for each outcome.
Discussion
Many middle-aged and older adults may be at elevated risk not only for severe COVID-19 morbidity and mortality but also adverse psychological, social and economic consequences of the pandemic.1 2 7 11 We established the COVID-19 Coping Study to provide publicly available data on the mental health and well-being of middle-aged and older adults as affected by social and economic changes during the COVID-19 pandemic. A total of 6938 study participants aged ≥55 years took part across all 50 US states, the District of Columbia and Puerto Rico. This study will provide rich longitudinal quantitative and qualitative data on physical isolation, social and economic changes, living circumstances, COVID-19 symptom and testing history, health behaviours and a range of mental health, cognitive health and well-being outcomes. The COVID-19 Coping Study may provide timely evidence to inform policy interventions to support mental health and coping throughout the pandemic, such as digital technologies for connectivity, enhanced mental health service provision, public education campaigns and socially supportive municipal infrastructures.2
Pre-pandemic data from the nationally representative US Health and Retirement Study (HRS) and National Social Life, Health and Aging Project (NSHAP) indicate a slight U-shaped pattern in depressive symptoms and loneliness with increasing age beyond 50 years and 65 years, respectively.45 46 We observed decreased prevalence with increasing age, consistent with other emerging data from the early pandemic period.47 In the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) in 2004/2005, the prevalence of any anxiety disorder according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria among adults aged ≥55 years was 11.39%.48 Prevalence in the NESARC declined with age, consistent with our data, although we observed a higher prevalence of anxiety symptomology at all ages in this study. A recent meta-analysis of anxiety disorder prevalence among older adults indicated under-diagnosis in this age range.49 Longitudinal data from our study will be valuable for assessing the effects of specific pandemic-related exposures on changes in mental health symptomology and outcomes, and can be triangulated in the future against data from ongoing cohorts like the HRS and NSHAP.50
As evidenced by the Domestic Public Health Response to COVID-19, public health interventions often support the interests of population groups who are likely to fully recover from COVID-19.51 This excludes the specific needs of older adults, who are at higher risk of severe COVID-19 morbidity and mortality, and may perpetuate age-based health disparities. The present study collects open-ended participant reflections on factors that are influencing their mental health, and how they are addressing stressors and life changes related to the ongoing pandemic. These qualitative data recognise that identity markers, such as ethnicity, race, gender, income and language, are not independent of one another, but rather can create a complex convergence of oppression and disparity if left unacknowledged.52 Effective interventions must address multiple intersecting dimensions of identity, positionality and social systems. Evidence on how these intersections are related to health inequities brought about and exacerbated by the COVID-19 pandemic will strengthen efforts to support diverse middle-aged and older adults throughout and after the pandemic.
Strengths and limitations
The COVID-19 Coping Study has some important limitations. This study was launched during the first upswing of a major pandemic, and did not capture people who may have been too sick to take part in the study, such as those who were hospitalised with COVID-19 or other health conditions. In our upcoming reports, we will compare our study sample prevalence of COVID-19 to published population data to evaluate and correct for any bias this may introduce into our estimates, as appropriate. Men, older adults from racial and ethnic minority groups, Spanish speakers and those with high school education or less were under-represented in the snowball sampling frame relative to the general population. This may limit sample size for some stratified analyses, and may affect internal validity for certain analyses if these factors are correlated with a given exposure and outcome under study. The population weights we generated using the American Community Survey data should reduce any potential selection bias due to these and other sociodemographic factors in estimates of the primary mental health outcomes under study. However, the weights may not account for unmeasured drivers of sample selection, and may not necessarily allow the estimation of population-representative prevalence estimates.
All study data were self-reported and subject to recall error. Missing data among completed questionnaires were uncommon, with most variables being complete or having less than 5% of observations missing. We recruited for this study and collected data using online methods, so our findings may not be generalisable to non-internet users. Although internet use is high among older adults in the USA, especially when considering access to mobile data through smartphones, individuals unable to use the internet during the recruitment period due to barriers such as illness, disability or financial access could not participate.53 While our snowball sampling recruitment method was intended to enhance coverage of individuals who do not use the internet or social media very often, this strategy assumes sufficient social network intensity between those who are and who are not on social media. However, the online modality allowed us to rapidly conduct this research at a low cost during a rapidly unfolding pandemic that limited physical interaction and affected people’s lives in dramatic ways. We experienced strong snowball-based recruitment for this study, indicating the public’s willingness to take part in COVID-19 research at a time when daily life has been disrupted at unprecedented levels in the USA and around the world.
Strengths of this study include its national coverage, large sample size, quantitative and qualitative mixed-methods approach and ability to longitudinally track within-person changes in mental health and well-being among middle-aged and older adults during the COVID-19 pandemic. Individual-level data are linked to geographic identifiers, which enables future analyses of area-level exposures including racial residential segregation, poverty, service access, COVID-19 burden and pandemic control policy changes. Our data collection overlapped with nationwide Black Lives Matter protests against racism and police violence sparked by several murders including those of George Floyd, Breonna Taylor and Ahmaud Arbery between February and May 2020.54 While not presented in this report, we have observed in-depth reactions to these events in the open-ended questionnaire responses. We will analyse these qualitative data in relation to changes in mental health outcomes following these events. Our use of qualitative and quantitative approaches can help generate novel hypotheses on how social, political, economic and public health circumstances in the USA affect middle-aged and older adults’ mental health.45 55 56
Conclusion
The COVID-19 Coping Study is a nationwide, longitudinal mixed-methods cohort study that aims to identify the effects of social and economic upheaval during the COVID-19 pandemic on mental health, cognitive health and well-being among US adults aged ≥55 years. Our baseline data indicate substantial self-reported effects of COVID-19 on daily life and employment among middle-aged and older US adults, and prevalent age-graded mental health symptoms during the first upswing of the pandemic in this population group. The COVID-19 Coping Study will provide needed empirical evidence on the specific challenges and resiliencies of middle-aged and older adults during the pandemic. Results may inform equitable public health interventions to harness positive coping strategies, foster social support and encourage meaningful daily activities among ageing populations during times of stress and trauma.
