Participants and Procedure
Data were collected from a sample of U.S. adults recruited through the online platform, Prolific (prolific.co), from April 21 to April 23, 2020. At this point in the pandemic, most U.S. states were under stay-at-home or shelter-in-place orders to mitigate the spread of COVID-19 (Moreland et al. 2020) which required “non-essential” businesses to operate remotely and discouraged non-essential travel. Additionally, over 2.4 million cases of COVID-19 had been confirmed globally, including over 170,000 deaths, and the United States was leading the world in confirmed COVID-19 cases and related deaths (World Health Organization 2020b). Although a convenience sample, participants were selected to approximate the distribution of age, sex, and race in the U.S. Prolific creates population strata based on gender (male/female), age (18–27, 28–27, 38–47, 48–57, and 58 and older), and race (White, Black, Asian, Mixed, Other) based on U.S. Census Bureau estimates and individuals may take the survey if there is a space available matching their demographic characteristics. After providing online consent by selecting “I agree” to participate, individuals completed an anonymous survey assessing their perceptions and behaviors related to the COVID-19 outbreak and received $2 for their time. This protocol was reviewed by the University of Colorado Boulder IRB and designated exempt due to the low risk associated with participation.
In total, 813 individuals responded to the online survey. Those who discontinued participation (n = 12) and those who did not answer at least two of the three attention check questions correctly (n = 6) were excluded. Data were examined for other patterns indicative of invalid responses (e.g., invariability in responses, speeding) and no additional respondents were identified for exclusion. The final sample included 795 participants (50.6% female). Participants were on average 45.33 years old (SD = 16.24; 18–80). The majority were Non-Hispanic White (70.9%), had at least some college education (89.6%), and approximately half (53.2%) reported an annual household income of $50,000 or more. The sample included respondents from all 50 states and Washington, D.C. Table 1 provides the descriptive characteristics of this sample.
Table 1 Descriptive information (N = 795) Measures
Assessments of cognitive and affective risk beliefs were formatted similar to our prior work (Magnan 2017; Magnan et al. 2009; Montanaro and Bryan 2014). Means for each assessment are provided in Table 1.
Perceived likelihood
Perceived personal likelihood of contracting COVID-19 was assessed with eight items asking participants to indicate what they thought the chances are that they would get COVID-19 and how likely they think they were to get COVID-19 over four time periods: the next two weeks, next month, next six months, and next year. Responses were made on 7-point response scales (1 = extremely unlikely/very low, 7 = extremely likely/very high). These items were averaged to create a single personal likelihood score (α = 0.93). Perceived risk to others was assessed with “What do you think the chances are that the average person your age will get COVID-19 in the” … next two weeks, next month, next six months, next year (α = 0.86). For descriptive purposes, means for perceived likelihood for each timeframe (for self and others) are provided in Table 1 along with the overall scores.
Perceived severity
Perceived personal severity of COVID-19 was assessed with four items: “How bad would you find it if you got COVID-19?” “If I got COVID-19 it would be very disruptive to my life,” “If I got COVID-19 it would have little effect on my life” (reversed), and “If I got COVID-19, I would show no or only mild symptoms” (reversed). Responses were made on 7-point response scales (1 = not too bad/extremely disagree, 7 = very bad/extremely agree). Items were averaged to create a single personal severity score (α = 0.78). Perceived severity to others was assessed with a single item: “How bad do you think it would be for the average person your age if they got COVID-19?” (1 = not too bad, 7 = very bad).
Worry
Similar to perceived likelihood, participants indicated how worried they were about getting COVID-19 and how often they worried about getting COVID-19 over four time periods: the next two weeks, next month, next six months, and next year. Two additional questions asked “How worried have you been in the past two weeks about getting COVID-19?” and “How often in the past two weeks did you worry about getting COVID-19?” Responses were made on 7-points scales (1 = not at all/never; 7 = extremely/very often). Items were averaged to create a single personal worry score (α = 0.96). Perception of others’ worry was assessed with “How worried do you think the average person your age is about getting COVID-19 in the”… next two weeks, next month, next six months, next year (α = 0.89). Means for each worry timeframe (for self and others) are provided in Table 1 along with the overall scores.
Protective behaviors
Participants indicated how often they engaged in a series of behaviors in the past two weeks on a 7-point response scale (1 = never, 7 = very often). We asked about behaviors recommended by the Centers for Disease Control and Prevention (CDC) to curb the spread of the virus (Centers for Disease Control 2020) and also behaviors that people may engage in during the stay-at-home orders: (1) stayed at home as much as possible, (2) avoided large crowds, (3) maintained social distance (6 ft) when out, (4) congregated in large crowds (reversed), (5) went to friends’/family’s houses (reversed), (6) avoided touching face as much as possible, (7) washed hands with soap and water for at least 20 s, (8) covered nose and mouth to cough/sneeze, (9) wore a face covering (e.g. face mask) when out, (10) went to grocery stores when needed, (11) got take-out/delivery when needed and (12) left home to exercise (e.g. walk). We originally anticipated treating this assessment as a single score. However, principal components analysis with varimax rotation identified a four-component solution for the behavior measure when considering eigenvalues above 1. Table 2 presents the component loadings and means for each behavior. Variance explained was 60.76%. Component 1 included social distancing (items 1–5, α = 0.96), eigenvalue = 3.24; Component 2 included personal hygiene (items 6–9, α = 0.64), eigenvalue = 1.81; Component 3 included leaving the home for food (items 10–11, α = 0.53), eigenvalue = 1.23; and Component 4 included a single item, leaving the home to exercise (item 12), eigenvalue = 1.02.
Table 2 Component loadings and individual behavior means Risk score
Participants indicated if they experienced health conditions that may put them at risk according to the CDC (Centers for Disease Control 2020): diabetic, renal failure, liver disease, autoimmune disorder, live in nursing home/long-term care facility, chronic lung disease, moderate/severe asthma, serious heart condition, immunocompromised (including current cancer treatment), currently smoke, currently vape (use electronic cigarettes). We also calculated BMI (40 or higher) and age (65 or older). A sum score was created such that higher numbers indicated a greater number of risk factors (possible range 0–13).
Location of residence
Participants indicated if they lived in a rural, suburban, or urban neighborhood.
Information sources
Participants indicated where they typically get their information about COVID-19 (choosing all that applied). Options included social media (50.2%), Centers for Disease Control or other health organization (54.5%), local news television/radio/newspaper outlet (63.8%), and national television/radio/online news outlet (70.7%). If a national outlet was identified, participants indicated which from a list of 11 major national news outlets. We categorized these outlets into liberal, neutral, and conservative outlets based on ratings from the media bias monitoring website AllSides.com (e.g., Ribeiro et al. 2018). Next, we coded liberal outlets (e.g., New York Times) as − 1, neutral outlets (e.g., PBS) as 0, and conservative outlets (e.g., Fox News) as + 1. We then computed an average media source bias score by summing the values of the news outlets each participant selected and dividing this number by the total number of outlets they selected. A negative score on this variable indicates that a participant gets their information about COVID-19 from more liberal news outlets, while a positive score indicates that a participant gets their information about COVID-19 from more conservative news outlets. Participants who did not endorse getting their information about COVID-19 from national news outlets did not receive a score on this variable.
Analysis
Descriptive information was first generated by calculating means and frequencies. Nine individuals identified their gender as non-binary. Because of the small number, they were excluded from any analysis that included gender. After examination of the distributions, two variables were dichotomized prior to analysis. Half of the sample (49.7%) scored a mean of 7 for the social distancing measure (1 = consistent social distancing vs. 0 = not) and over half the sample (56.7%) had a risk score of 0 (1 = any risk vs. 0 = no risk). Point-biserial correlations with the dichotomized social distancing variable were used to test bivariate associations between beliefs, other behaviors and social distancing behavior. Pearson’s correlations were used to test bivariate associations of continuous variables. One-way ANOVAs (for continuous outcomes) and logistic regression (for the social distancing dichotomous outcome) tested any group differences (i.e. gender, race (% White), risk group, location of residence, and media source bias) on cognitive and affective beliefs and behavior. Finally, multiple regression for continuous behavior outcome variables and logistic regression for social distancing included all cognitive and affective beliefs as predictors of behavior controlling for relevant demographic characteristics associated with cognitive and affective beliefs and/or behavior outcomes. Before being entered into the regression, all continuous variables were mean centered. Demographic characteristics were entered at Step 1, cognitive and affective beliefs at Step 2, and each cognitive X worry interaction (i.e. personal risk X worry, personal severity X worry, other risk X other worry, and other severity X other worry) at Step 3. Given the large sample and number of tests, we used a conservative alpha of p ≤ 0.001. We also explored whether demographic factors moderated the main effects of beliefs on behavior but saw no evidence that this was the case, so do not report those outcomes.
