Mask-wearing behavior during the COVID-19 pandemic in Korea: The role of individualism in a collectivistic country

Extending and Testing Protection Motivation Theory in the Context of COVID-19 Contact-Tracing Technology: A Comparison of South Korea and the United States

This study applies protection motivation theory (PMT) to the COVID-19 contact-tracing context by including privacy concerns, collective efficacy, and a mediator (fear of COVID-19) and tests it in the US and South Korea. The study uses a structural equation modeling (SEM) approach and a sample of 418 Americans and 444 South Koreans. According to the results, fear was positively associated with adoption intentions in the US sample but not in the Korean sample. Coping appraisals positively affected adoption intentions in both samples. However, while all types of coping appraisals were significant in the Korean sample, response efficacy was the only significant predictor among US participants. Privacy concerns were negatively associated with adoption intentions in the US sample, but not in the Korean sample. The results indicate that differences exist in the mediating role of fear connecting threat appraisals and adoption intentions in both countries. These findings hold important implications for future studies in AI-based health communication, especially in the areas of privacy management, protection motivation, and diverse cultural contexts.

Comparison of the efficacy of COVID-19 responses in South Korea and the United States

BACKGROUND

The COVID-19 pandemic devastated many countries worldwide by causing large numbers of fatalities. In our research, we wanted to answer the question: Why was there such a large difference in the mortality rate between South Korea and the United States? This is because many East Asian countries, such as Korea, had a lower mortality rate than many countries, including developed ones, across the world - the mortality rate of South Korea was about five times lower than the United States.

METHODS

This study comprehensively compares strategies used to address the COVID-19 pandemic in two different countries: South Korea and the United States. The various aspects of these two countries' responses are examined, including initial response, information dissemination and public compliance, mitigation strategies, and vaccine rollout and their impacts.

RESULTS

Early and widespread testing, rigorous contact tracing, the clear release of government information, and an organized vaccine rollout powered a proactive approach in South Korea. The United States had a contrasting response consisting of delayed and more decentralized measures, where testing lagged due to varying policies and the political controversies facing vaccine distribution.

CONCLUSIONS

We signify the gravity of rapid response and testing, clear communication, and efficient vaccine distribution, as we believe this could correlate with a lower mortality rate. In addition, we discuss future directions, including the need for a specific health infrastructure and protocol against highly infectious outbreaks.

Association Between Risk Perceptions of COVID-19, Political Ideology, and Mask-Wearing Behavior After the Outbreak: A Cross-Sectional Survey in South Korea

Purpose

After the declaration by the World Health Organization signaling the conclusion of the COVID-19 pandemic, most countries lifted mandatory mask-wearing regulations. This study aimed to investigate factors such as risk perception and political ideology associated with continued adherence to mask-wearing among specific populations, particularly when it is no longer deemed necessary.

Methods

We conducted a cross-sectional study including a sample of 1001 respondents stratified by sex, age (≥ 18 years), and region from January 31 to February 2, 2023, after the mandatory mask regulation was lifted in South Korea. Multivariate logistic regression models were applied to estimate the relationships between risk perceptions, political ideology, and mask-wearing maintenance, adjusting for factors such as sex, age, occupation, and trust in the government.

Results

Our results indicated significant associations between age, self-reported household economic status, political ideology, affective risk perception, and perceived effectiveness of the government's COVID-related measures with indoor mask-wearing. Specifically, liberals were more likely to keep mask-wearing indoors than conservatives (adjusted odds ratio [aOR]: 2.19; 95% confidence interval [CI]: 1.33-3.59); and those who perceived a greater affective risk of COVID-19 (aOR: 2.47; 95% CI: 1.96-3.10), along with those who perceived the government's countermeasures as inadequate, were more inclined to maintain the habit of wearing masks indoors (aOR: 1.90; 95% CI: 1.19-3.03).

Conclusion

Our study highlighted the multifaceted factors influencing mask-wearing behavior in the post-COVID-19 era. Even after adjusting for various confounding factors, such as age, sex, and trust in the government, an association remained between affective risk perception, political ideology, and mask-wearing behavior. However, further research for psychological mechanisms is needed to foster a culture of preventive behaviors proportional to the risk of infection.

The role of collectivism, liberty, COVID fatigue, and fatalism in public support for the zero-COVID policy and relaxing restrictions in China

BACKGROUND

China was the last country in the world to relax COVID-19 restrictions. A successful public health policy requires public support. This analysis examined the factors associated with Chinese support for zero-COVID and relaxing COVID-19 restrictions in China.

METHOD

Two online surveys were conducted among Chinese participants in mainland China on June 10-13 (N = 460) and December 2, 2022 (N = 450). These two samples were similar based on the participants' demographics.

RESULTS

The results revealed that the perceived health consequences of a COVID-19 policy, perceived norms of approving a COVID-19 policy, and hope positively predicted the participants' support for the COVID-19 policy. The results further showed that collectivism and fatalism positively predicted support for zero-COVID and negatively predicted support for relaxing restrictions. COVID fatigue was negatively associated with support for zero-COVID and positively associated with support for relaxing restrictions. Liberty positively predicted support for relaxing restrictions in June and negatively predicted zero-COVID in December 2023. It did not positively or negatively predict support for the policy adopted by the government.

CONCLUSION

Collectivism, liberty, COVID fatigue, and fatalistic beliefs are important considerations connected to public support for a COVID-19 policy. The role of liberty was more nuanced and depended on the survey's time and whether the government adopted the policy.

Rapid estimation of tire-wear particle concentration in road dust using PM10 and traffic data in a ternary plot

Air pollution, a pressing global issue, is significantly exacerbated by airborne particulate matter (PM), affecting air quality and human health. Urban vehicular activities majorly contribute to PM rise through both exhaust and non-exhaust emissions. Despite strides in managing exhaust emissions, non-exhaust particles, such as tire wear particles (TWP) remain under-addressed. This research proposes a method for estimating TWP concentrations using PM10 data and traffic activity, which could offer a valuable tool for controlling roadside fine particles and TWP. This paper introduces a ternary plotting technique and step-by-step procedure to estimate TWP levels in road dust using only PM10 and traffic data. Traditional analysis of TWP via pyrolysis-gas chromatography-mass spectrometry is complex and time-consuming. Hence, our proposed approach presents an alternate method that leverages readily accessible PM and traffic data, providing critical information for road management interpretation. The triangular plot analysis demonstrated a linear correlation: [log(Traffic) + 2]-[250,000/TWP-13]-0.18PM10. While the resulting correlation may vary based on specific road conditions, the method can be tailored to different regions, offering insights into efficient estimation of TWP concentrations and promoting improved roadside pollution management.

Characteristics of victim blaming related to COVID-19 in South Korea

This study aimed to determine the characteristics of the victim-blaming tendency of patients with coronavirus disease-2019 (COVID-19) and the worry of being blamed because of COVID-19 infection. This study utilized two methodologies based on the theory of defensive attribution and information processing. First, a media analysis was conducted to determine the characteristics of the two representative COVID-19 victim blaming cases (the Itaewon Club case and the Omicron-infected pastor case). The results show that from the viewpoint of defensive attribution theory, the victim blaming of patients infected with COVID-19 is related to social identity and moral violations committed by the patients. The Korean public emphasized their social identity and believed that the patients were different from them from an ego-defensive viewpoint. Second, we conducted three longitudinal online panel surveys (N1 = 1569; N2 = 1037; N3 = 833). The samples were selected by stratified random sampling based on sex, age, and 17 metropolitan regions in Korea. The results showed that as the number of COVID-19 cases increased, the respondents' level of risk perception decreased significantly. As the information processing theory explains, people who are familiar with the frequent risks of COVID-19 are less worried about being blamed by others. Meanwhile, the regression analysis found that victim blaming of the pastor was significantly related to the respondent's religion. We can conclude that the Korean people may blame the victims of COVID-19 because they believe that the victims are very different from an ego-defensive viewpoint. Furthermore, the trust variable appeared to be important: the more the respondents trusted the government, the more they blamed the victims of COVID-19. We term this phenomenon the "trust paradox."

Filter Masks during the Second Phase of SARS-CoV-2: Study on Population

During the SARS-CoV-2 pandemic, the most common countermeasure are the use of masks, which are supposed to filter inhaled and exhaled air to reduce the spread of the virus. The masks, which are medical devices, must be used by providing appropriate instructions for correct use. This study, which examined the population during the advanced stage of the pandemic, highlighted a substantial improvement in the management and choice of masks, even though the information disseminated to the population probably should be even more detailed and precise in order to avoid incorrect behavior that could compromise the effectiveness of these devices; in fact a high percentage of subjects had behaviors that can facilitate the spread of the virus, such as the continuous attempts to correct the incorrect positioning of the mask on the face or the need to move it because it is annoying.

Factors Associated with Handwashing Behaviors During the COVID-19 Pandemic: An Analysis of the Community Health Survey in Korea

Introduction

Handwashing is the most effective preventive behavior for coronavirus disease-19 (COVID-19) infection. However, research has shown the lower handwashing behaviors among Korean adults.

Objectives

This study aims to analyze factors associated with handwashing as a preventive behavior for COVID-19 infection based on the health belief model (HBM) and the theory of planned behavior (TPB) behavioral theories.

Methods

This secondary data analysis utilized the Community Health Survey developed by Disease Control and Prevention Agency conducted in 2020. Sampling method was stratified and targeted 900 people living in the territory of each community public health center. In total, 228,344 cases were used in the analysis. Handwashing behavior, perceived susceptibility, perceived severity, subjective norm, and influenza vaccine uptake were used in the analysis. Regression analysis using weighing strategy by stratification and domain analysis was used.

Results

Less washing hand was associated with older age (B = 0.01, p < .001), males (B = 0.42, p < .001), not receiving an influenza vaccine (B = 0.09, p < .001), perceived susceptibility (B = 0.12, p < .001), subjective norm (B = 0.05, p < .001), and perceived severity (B = -0.04, p < .001).

Conclusion

While perceived susceptibility and social norm had positive association, perceived severity had a negative association with handwashing. Considering the Korean culture, creating a shared norm for frequent handwashing could be beneficial to promote handwashing rather than emphasizing the disease and its consequences.
