T17 0-15 Sentence denotes 1 Introduction
T18 16-148 Sentence denotes From COVID-19, MERS and SARS to H1N1, Zika and Ebola, people around the world have been facing rampant waves of infectious diseases.
T19 149-229 Sentence denotes New pandemics are anticipated to occur at an increasing frequency (Wolfe, 2011).
T20 230-338 Sentence denotes Yet the current understanding of how an outbreak influences people's psychological well-being is incomplete.
T21 339-699 Sentence denotes Much prior research has focused on well-being differences across, for example, gender (Wood, Rhodes, and Whelan, 1989), age (Steptoe, Deaton, and Stone, 2015), degrees of social connectedness (Myers, 1999), income levels (Kahneman and Deaton, 2010), individual dispositions (Diener and Seligman, 2002), and consumption patterns (Dunn, Aknin, and Norton, 2008).
T22 700-865 Sentence denotes However, relatively little is known about how an increasingly common phenomenon—epidemic outbreak—impacts emotional well-being (Lu et al., 2020, Zhang et al., 2020).
T23 866-970 Sentence denotes Even less is known about the factors that may worsen or protect emotional well-being during an outbreak.
T24 971-1142 Sentence denotes Identifying these factors is critically important, as they inform policies and interventions aimed at protecting people's psychological well-being in the age of pandemics.
T25 1143-1302 Sentence denotes We sought to add to this understanding through two large-scale nationwide surveys conducted in China immediately before versus during the coronavirus outbreak.
T26 1303-1405 Sentence denotes We found that the onset of the epidemic in China led to a 74% decline in overall emotional well-being.
T27 1406-1555 Sentence denotes Individuals who were residing near the epicenter of the outbreak, of an older age, or married, experienced a steeper decline in emotional well-being.
T28 1556-1767 Sentence denotes This suggests that factors associated with, respectively, the likelihood of contracting the disease, extent of potential harm, and relational issues are moderators of well-being deterioration during an epidemic.
T29 1768-2020 Sentence denotes Perhaps more importantly, we found that, during the coronavirus outbreak, individuals’ perceived level of knowledge about coronavirus infection was a stronger “protector” of their emotional well-being than the actual amount of knowledge they possessed.
T30 2021-2195 Sentence denotes We propose that this is because a higher level of perceived knowledge can lead to a stronger sense of control, which in turn protects emotional well-being during an outbreak.
T31 2196-2444 Sentence denotes This proposition was supported by the results of our analyses: sense of control was a mediator of the impact of perceived knowledge on emotional well-being (even after controlling for actual knowledge as well as demographic and economic variables).
T32 2445-2595 Sentence denotes The finding thus suggests that factors boosting sense of control can alleviate the detrimental effect of an epidemic outbreak on emotional well-being.
T33 2597-2607 Sentence denotes 2 Methods
T34 2608-2742 Sentence denotes Our data came from two nationally representative surveys of individuals living in China before versus during the coronavirus outbreak.
T35 2743-2893 Sentence denotes Both surveys were administered by the Data Intelligence and National Development Lab of Peking University using the same nationwide participant panel.
T36 2894-3122 Sentence denotes The first survey (N = 11,131; from 32 provincial regions; 48% women; average age of 37.78; 66% married) was administered at the end of December 2019 (immediately before the coronavirus outbreak was publically reported in China).
T37 3123-3283 Sentence denotes The second survey (N = 3,000; from 30 provincial regions; 50% women; average age of 34.7; 69% married) was conducted in mid-February 2020 (during the outbreak).
T38 3284-3398 Sentence denotes Participants in both surveys completed an established measure of emotional well-being (Kahneman and Deaton, 2010).
T39 3399-3589 Sentence denotes Specifically, they indicated whether they smiled or laughed a lot yesterday, and whether they experienced a lot of enjoyment/happiness/anger/sadness/stress/worry yesterday (1 = yes, 0 = no).
T40 3590-3732 Sentence denotes Participants in both surveys also responded to demographic measures: age, sex, marital status, monthly household income, and residence region.
T41 3733-3862 Sentence denotes Participants in the second survey responded to additional measures pertaining to perceived knowledge about coronavirus infection.
T42 3863-4074 Sentence denotes They indicated how much knowledge they had about how the coronavirus spreads from person to person, as well as how much knowledge they had about preventing coronavirus infection (1 = very little, 5 = very much).
T43 4075-4169 Sentence denotes They also completed measures regarding their sense of control during the coronavirus outbreak.
T44 4170-4471 Sentence denotes They indicated the extent to which they had control over the circumstances they were facing (1 = very much lack control, 5 = very much have control) and the extent to which they were confident that they could manage not to be infected by the coronavirus (1 = not confident at all, 5 = very confident).
T45 4472-4682 Sentence denotes Finally, they completed five multiple-choice questions (adapted from the information officially released by China's CDC) that assessed their actual level of knowledge regarding preventing coronavirus infection.
T46 4683-4833 Sentence denotes These questions covered effective handwashing, disinfectant usage, mask usage, avoidance of mouth/eye/nose touching, and prevention of droplet spread.
T47 4834-5143 Sentence denotes Following an established approach (Diener et al., 2010), we constructed an index of emotional well-being by subtracting the average of the negative affect measures (anger, sadness, stress, and worry; α = .769) from the average of the positive affect measures (smile/laugh, enjoyment, and happiness; α = .691).
T48 5144-5212 Sentence denotes This overall index served as the dependent variable in our analyses.
T49 5213-5318 Sentence denotes We coded whether participants were residing in Hubei Province, the epicenter of the coronavirus outbreak.
T50 5319-5484 Sentence denotes Because the monthly household income measures used in the two surveys differed in the number of income brackets offered, we transformed them for use in our analyses.
T51 5485-5827 Sentence denotes Specifically, due to the ordinal nature of the scale items (e.g., 5,000-7,999 RMB; 8,000-11,999 RMB; … 50,000 RMB or higher), we, following an established approach (Hout, 2004), recoded each response by taking the midpoint (e.g., 6,499 RMB) of the respective income interval when a fixed-range scale item was selected (e.g., 5,000-7,999 RMB).
T52 5828-5958 Sentence denotes When an open-range item was chosen (e.g., 50,000 RMB or higher), we recoded the response using the lower bound (e.g., 50,000 RMB).
T53 5959-6093 Sentence denotes We then linearly transformed the value by dividing it by 1,000 so that the monthly household income is measured in units of 1,000 RMB.
T54 6094-6233 Sentence denotes Furthermore, we averaged the items for perceived knowledge (r = .595) and sense of control (r = .579), respectively, into a single measure.
T55 6234-6377 Sentence denotes We also counted the number of objective knowledge questions each participant answered correctly, which served as a measure of actual knowledge.
T56 6379-6389 Sentence denotes 3 Results
T57 6390-6473 Sentence denotes We first compared the data collected before versus during the coronavirus outbreak.
T58 6474-6661 Sentence denotes We found that the outbreak significantly degraded emotional well-being (M before = .437, SD before = .568; M after = .114, SD after = .626; F(1, 14129) = 728.808, p < .001)—a 74% decline.
T59 6662-7040 Sentence denotes We ran a series of regressions with emotional well-being as the dependent variable, and the coronavirus outbreak (1 = during, 0 = before), whether the individual resided in Hubei (1 = yes, 0 = no), age, sex (1 = female, 0 = male), marital status (1 = married, 0 = not married), household income, and each of their interaction term with the outbreak as predictors (see Table 1 ).
T60 7041-7330 Sentence denotes The analyses not only established a consistent, significant negative effect of the outbreak on emotional well-being, but also revealed a set of significant interactions: (i) Individuals residing in Hubei, the epicenter of the outbreak, experienced a larger decline in emotional well-being.
T61 7331-7715 Sentence denotes Because the overwhelming majority of Chinese coronavirus patients resided in that region (Dong, Du, and Gardner, 2020), this result suggests that a higher likelihood of contracting the disease accentuates the detrimental effect of an epidemic outbreak on emotional well-being. (ii) Those of an older age also experienced a larger reduction of emotional well-being during the outbreak.
T62 7716-8276 Sentence denotes Because the coronavirus tends to cause more harm to the elderly than people of a younger age (CDC, 2020), this pattern suggests that the extent to which an individual might suffer from contracting the disease moderates the effect of an epidemic on the person's emotional well-being. (iii) Individuals who were married also experienced a greater decline in emotional well-being, suggesting that enduring an outbreak (e.g., being in a confined space for extended periods of lockdown) can potentially exacerbate relational issues that worsen emotional well-being.
T63 8277-8404 Sentence denotes This pattern is consistent with the increase in marriage problems after the COVID-19 outbreak in China (Financial Times, 2020).
T64 8405-8485 Sentence denotes Neither income or gender had a significant interaction effect with the outbreak.
T65 8486-8552 Sentence denotes Table 1 The impact of coronavirus outbreak on emotional well-being

T115 13811-13913 Sentence denotes We tested whether sense of control mediated the effect of perceived knowledge on emotional well-being.
T116 13914-14019 Sentence denotes We ran a mediation analysis using a bootstrapping technique with 10,000 resamples (Model 4, Hayes, 2013).
T117 14020-14289 Sentence denotes This analysis indicated that perceived knowledge had a significant positive effect on sense of control (a = .37, SE = .02, t = 20.49, p < .001) and that sense of control had a significant positive effect on emotional well-being (b = .23, SE = .02, t = 12.49, p < .001).
T118 14290-14565 Sentence denotes Moreover, the otherwise significant direct effect of perceived knowledge on emotional well-being (c = .07, SE = .02, t = 3.55, p < .001) became non-significant (c’ = -.02, SE = .02, t = -.97, p = .33) after the indirect effect through sense of control was taken into account.
T119 14566-14709 Sentence denotes The 95% bias corrected confidence interval for the indirect effect did not include 0 (95% CI = [.07, .10]), indicating a significant mediation.
T120 14710-14815 Sentence denotes That is, sense of control mediated the relationship between perceived knowledge and emotional well-being.
T121 14816-15042 Sentence denotes As robustness checks, we reran the mediation analysis with emotional well-being as the dependent variable, perceived knowledge as the independent variable, actual knowledge as a covariate, and sense of control as the mediator.
T122 15043-15192 Sentence denotes This analysis also yielded a significant indirect effect of perceived knowledge on emotional well-being through sense of control (95% CI [.07, .10]).
T123 15193-15359 Sentence denotes We also reran the mediation analysis with actual knowledge, the demographic and economic variables and their interaction terms with perceived knowledge as covariates.
T124 15360-15501 Sentence denotes This again yielded a significant indirect effect of perceived knowledge on emotional well-being through sense of control (95% CI [.02, .11]).
T125 15502-15584 Sentence denotes These mediation results provide evidence for our proposed psychological mechanism.
T126 15585-15774 Sentence denotes That is, participants’ perceived knowledge about coronavirus infection was associated with a higher sense of control, which in turn protected their emotional well-being during the outbreak.
T127 15776-15789 Sentence denotes 4 Discussion
T128 15790-16077 Sentence denotes Overall, this research contributes to the literature on emotional well-being by exploring how an increasingly common phenomenon—epidemic outbreak—influences emotional well-being and by identifying a number of factors that can worsen (vs. protect) emotional well-being during an outbreak.
T129 16078-16426 Sentence denotes Specifically, our results suggest that factors associated with the likelihood of contracting a disease (e.g., living close to the epicenter of an outbreak), extent of potential harm (e.g., being an elderly), and relational issues (e.g., those within a marriage) can exacerbate the detrimental effect of an epidemic outbreak on emotional well-being.
T130 16427-16525 Sentence denotes Further, individuals’ perception of their knowledge about an epidemic is another important factor:
T131 16526-16703 Sentence denotes Regardless of their actual level of knowledge, those perceiving themselves as more knowledgeable, can better shield their emotional well-being from declining during an outbreak.
T132 16704-16835 Sentence denotes This occurs because a higher level of perceived knowledge can lead to a stronger sense of control, protecting emotional well-being.
T133 16836-16957 Sentence denotes In other words, approaches that boost sense of control, can attenuate the detrimental effect of an outbreak on happiness.
T134 16958-17118 Sentence denotes These findings inform future research, and offer insights for policies and interventions aimed at caring for people's psychological well-being during epidemics.
T135 17120-17153 Sentence denotes Declaration of Competing Interest
T136 17154-17214 Sentence denotes The authors declare that there are no conflicts of interest.
