Q2. What are the future works mentioned in the paper "Associations of risk perception of covid-19 with emotion and mental health during the pandemic" ?
Since the analyses on risk perception and emotion were based on cross-sectional data, the direction of causal links between them, and the mediating role of emotion in the risk perception-mental health association need to be confirmed by future longitudinal or experimental studies. The emotion regulation during the pandemic could also influence mental health in people with high risk perception and warrants further research ( Restubog et al., 2020 ). These factors may influence the risk perception of COVID-19 and lead to potential residual confounding bias.
Q3. What was used to deal with missing values on covariates in this study?
Complete case analysis was used to deal with missing values on covariates in this study (each covariate had 0 to <1% missing values).
Q4. What is the importance of a comprehensive understanding of the association between risk perception and mental health?
A comprehensive understanding of the association between risk perception and mental health is crucial for developing relevant preventive interventions and social policies during the pandemic.
Q5. What was the effect size of the reversal of negative emotions?
In this analysis, the scores of negative emotions were reversed for consistency with positive emotions so that a higher score reflects a lower level of negative emotions.
Q6. What is the effect of adjusting for covariates?
Not adjusting for covariates (median standardised β=-0.186, median SE=0.004) or only adjusting for basic demographics yielded similar effect estimates (median standardised β=-0.182, median SE=0.004), whereas adjusting for a full set of covariates resulted in a weaker independent effect of risk perception on emotion (median standardised β=-0.136, median SE=0.005).
Q7. What is the way to check if the user gave explicit consent?
IP checkIndicate whether the IP address of the client computer was used to identify potential duplicate entries from the IP addresses were only collected if participants gave explicit consent to do so.
Q8. Why was the standardised regression coefficient recommended as an optimal effect size?
No conventional effect size was computed in this study because all models were multilevel linear regressions with random-intercept, for which the standardised regression coefficient has been recommended as one of the optimal effect sizes to represent the magnitude of fixed effects (i.e., associations between explanatory and response variables), especially when working with large samples (Lorah, 2018).
Q9. What is the main aspect of the risk perception of COVID-19?
In the context of the COVID-19 pandemic, the concerns of getting infected and the economic consequences have been proposed as two major aspects of risk perception of COVID-19 and assessed by several preliminary studies (Soiné et al., 2020; Bruine de Bruin, 2020).
Q10. What is the effect of the standardised =-0.168?
In addition, the economic-risk was in stronger association with emotion (median standardised β=-0.165, median SE=0.004) than the infection-risk (median standardised β=-0.139, median SE=0.004).
Q11. What are the main reasons for the association between risk perception and emotional responses to the Ebola?
Yang and Chu (2018) also associated risk perception about the Ebola outbreak with some negative emotions like fear, anger, anxiety, disgust, and sadness.
