Comparison of Psychosocial Distress in Areas With Different COVID-19 Prevalence in Korea

The Effect of Fear of COVID-19 Infection and Anxiety on Loneliness: Moderated Mediation Effects of Gratitude

OBJECTIVE

This study was conducted to identify factors related to loneliness during the coronavirus disease-2019 (COVID-19) pandemic and focused on how the fear of COVID-19 infection affects loneliness and the conditional effect of gratitude as a moderator in the relationship among the fear of COVID-19, anxiety, and loneliness.

METHODS

For the analysis of this study, a survey was conducted among 1,500 individuals aged 19 to 69 years living in three metropolitan areas in South Korea. Questionnaires included sociodemographic data, psychological experience and stress associated with COVID-19, Generalized Anxiety Disorder Scale-7, UCLA Loneliness Scale-3, and Gratitude Questionnaire-6. An analysis was conducted by applying SPSS PROCESS macro models 4 and 7.

RESULTS

First, anxiety mediated the relationship between the fear of COVID-19 infection and loneliness. Second, the effect of the fear of COVID-19 infection on loneliness through anxiety was moderated by gratitude. The higher the gratitude, the more the fear of COVID-19 infection is buffered in the path to anxiety, and the lower the indirect effect on loneliness.

CONCLUSION

This suggests that in the context of the COVID-19 pandemic, interventions for psychological problems such as anxiety and loneliness can be carried out through gratitude, a significant protective variable.

Psychological and Personality Characteristics Associated With COVID-19 Vaccination Behavior in Korean General Population

BACKGROUND

This study characterized coronavirus disease 2019 (COVID-19) vaccination behavior in the Korean general population using cluster analysis and explored related psychological factors.

METHODS

We categorized 1,500 individuals based on their attitudes toward COVID-19 vaccination using hierarchical clustering and identified their level of vaccine acceptance. We examined the associations between vaccine acceptance and behavioral and psychological characteristics.

RESULTS

Clustering revealed three groups according to vaccine acceptance: 'totally accepting' (n = 354, 23.6%), 'somewhat accepting' (n = 523, 34.9%), and 'reluctant' (n = 623, 41.5%). Approximately 60% of all participants who belonged to the 'totally accepting' and 'somewhat accepting' groups were willing to receive a COVID-19 vaccine despite concerns about its side effects. High vaccine acceptance was associated with older age, regular influenza vaccination, and trust in formal sources of information. Participants with high vaccine acceptance had higher levels of gratitude, extraversion, agreeableness, and conscientiousness, and lower levels of depression, anxiety, and neuroticism.

CONCLUSIONS

People weighed the benefits of COVID-19 vaccination against the risk of side effects when deciding to receive the COVID-19 vaccine. Our findings also indicate that this vaccination behavior may be affected by coping mechanisms and psychological factors.

Effect of COVID-19 pandemic on serious mental illness-related outpatient department utilization in Ningbo, China: an interrupted time series analysis

Background

Globally, the coronavirus disease 2019 (COVID-19) pandemic has negatively affected mental health services, but there is no clear evidence of this in China. Therefore, we examined the effect of the COVID-19 pandemic on the use of serious mental illness (SMI)-related outpatient services in Ningbo, China.

Methods

We analyzed the trends in monthly SMI-related outpatient department utilization from January 2018 to June 2022 using interrupted time series (ITS) regression analysis, and we defined the onset of the COVID-19 pandemic as January 2020. We also performed ITS regression analyses for sex and age subgroups.

Results

A significant difference in the monthly number of outpatient visit slopes before and after the onset of the pandemic was shown in the SMI analysis [-175.6, 95% confidence interval (CI) (-338.3 to -12.9), p < 0.05]. All sex and age categories, except the 20-30 years age category, showed statistically significant changes in their slopes after the onset of the pandemic. Significant differences in the number of outpatient visit slopes before and after the onset of the pandemic were seen for schizophrenia and bipolar disorders [-153.3, 95% CI (-294.1 to -12.5) and -16.8 (-31.0 to -2.6), respectively]. Moreover, a negative relationship was observed between the monthly number of outpatient visits and the number of incidents and accidents due to SMI (r = -0.38, p < 0.05).

Conclusion

The COVID-19 pandemic has had a negative effect on SMI-related outpatient visits in Ningbo, especially by patients with schizophrenia. A strategy should be developed and implemented to maintain access to SMI services during the COVID-19 pandemic.

Trends in suicide deaths before and after the COVID-19 outbreak in Korea

We investigated the effect of the coronavirus disease-2019 (COVID-19) pandemic on suicide trends in Korea via a time-series analysis. We used Facebook Prophet to generate forecasting models based on the monthly numbers of suicide deaths in Korea between 1997 and 2018, validated the models by comparison with the 2019 numbers, and predicted the numbers of suicides in 2020. We compared the expected and observed numbers of suicides during the COVID-19 pandemic. The total numbers of suicides during the COVID-19 pandemic did not deviate from projections based on the pre-pandemic period. However, the number of suicides among women and those under the age of 34 years significantly exceeded the expected level. The COVID-19 pandemic did not increase the overall suicide rate significantly. However, suicides among women and young people increased, suggesting that the pandemic might drive more members of these groups to suicide. Further studies are needed to verify the long-term impact of the COVID-19 pandemic on suicide.

Factors Associated With Depression and Anxiety in Korean Adolescents During the COVID-19 Pandemic

OBJECTIVE

This study was performed to identify factors associated with depression and anxiety among Korean adolescents during the coronavirus disease (COVID-19) pandemic.

METHODS

We conducted a cross-sectional study of 1,898 Korean adolescents (55.2% male, 44.8% female) ranging in age from 12 to 17 years (mean±standard deviaion age, 15.4±2.6 years). Depression and anxiety were defined as a Patient Health Questionnaire-9 score ≥10 and Generalized Anxiety Disorder-7 score ≥10, respectively. Other questionnaires included sociodemographic data, psychosocial stresses, and experiences in association with COVID-19. Psychiatric scales included Gratitude Questionnaire-6, Perceived Stress Scale-10, and UCLA Loneliness Scale-3.

RESULTS

The prevalence rates of depressive and anxiety symptoms among participants were 13.8% and 21.0%, respectively. Multivariable logistic regression analysis revealed that female sex, fear of COVID-19 infection, low gratitude were risk factors for depression. Fear of COVID-19 infection, increased TV watching time, and academic-related stress were risk factors for anxiety.

CONCLUSION

Depression and anxiety were prevalent during the pandemic in Korean adolescents, and were associated with fear of COVID-19 infection. Providing appropriate information on COVID-19, helping adolescents manage academic-related stress and maintain daily life patterns, and implementing interventions to foster gratitude are important for preventing depression and anxiety in Korean adolescents.

Effects of COVID-19-related stress and fear on depression in schizophrenia patients and the general population

This study compared the coronavirus disease 2019 (COVID-19)-related stress, fear of infection, loneliness, and depression between patients with schizophrenia and the general population. A face-to-face survey was administered to 1340 patients with a schizophrenia spectrum disorder and online survey of the general population (n = 2000) was conducted. The information gathered included the level of COVID-19-related stress, fear of infection, the Patient Health Questionnaire-9 score, and the three-item UCLA Loneliness Scale score. Structural equation modeling revealed a significant effect of fear of COVID-19 infection on depression among the general population and on loneliness among patients with schizophrenia. Loneliness experienced during COVID-19 exacerbated depression in both groups. In the COVID-19-related stress-loneliness-depression pathway, the partial mediating effect of loneliness was significant in both groups. Conversely, in the COVID-19-related fear-loneliness-depression pathway, the full mediating effect of loneliness was only significant in patients with schizophrenia. In conclusion, the loneliness associated with COVID-19-related stress and fear of infection was an important factor influencing depression, and the impact was greater in patients with schizophrenia compared with the general population. Thus, different mental health intervention plans are needed for patients with schizophrenia during the COVID-19 pandemic. During the long-lasting COVID-19 pandemic, social support and provision of mental health services to prevent loneliness and consequent depression are required in patients with schizophrenia.

Decline in Hospital Visits by Patients with Schizophrenia Early in the COVID-19 Outbreak in Korea

Objective

This study investigated trends in hospital utilization by patients with schizophrenia during the first wave of the COVID-19 outbreak in Korea.

Methods

The Prophet algorithm was used to predict the monthly number of patients with schizophrenia in 2020 based on medical insurance data between 2010 and 2019. The projected expectations were compared with the actual number of patients receiving outpatient and inpatient treatment each month in the first half of 2020. We conduct interrupted time series analyses of short-term data to determine the significance of recent changes in the trend of hospital visits by patients with schizophrenia.

Results

The prediction model showed that the actual number of patients receiving treatment each month during the early COVID-19 outbreak decreased by up to 3.6% compared to the projected expectations. The interrupted time series model also revealed a significant change in hospital utilization compared to the year before the onset of COVID-19 in Korea (F = 8.961, p = 0.010).

Conclusion

This suggests that many patients with schizophrenia were not receiving adequate treatment during the COVID-19 outbreak. A strategy should be developed to keep treating patients with schizophrenia during the COVID-19 pandemic.

Depression During COVID-19 Quarantine in South Korea: A Propensity Score-Matched Analysis

Background

Quarantine, a public health measure used to control the coronavirus disease 2019 (COVID-19) pandemic, has been linked to an increased risk of developing adverse psychological sequelae. This study sought to investigate whether quarantining during the COVID-19 pandemic was associated with depression among Koreans.

Methods

Data were obtained from the Seoul COVID-19 Study of Quarantine (SCS-Q) and the 2019 Korea Community Health Survey (KCHS). Using propensity scores estimated based on sociodemographic and health conditions, 919 individuals undergoing quarantine in the SCS-Q were matched with 919 individuals who did not experience quarantine in the 2019 KCHS. Depressive symptoms were measured using the Korean version of the Patient Health Questionnaire-9 (PHQ-9), where major depression is defined as a PHQ-9 score ≥ 10. Logistic regression models were adjusted for sociodemographic and health-related factors.

Results

Depression prevalence was higher in quarantined individuals than in the control group (7.8 vs. 3.8%, p &lt; 0.001). Logistic regression analyses revealed that quarantining was associated with higher likelihoods of having major depression [odds ratio (OR) = 2.28, 95% confidence interval (CI): 1.49, 3.51] after adjusting for relevant covariates.

Limitations

Due to the online nature of the SCS-Q, this study included a limited number of elderly participants, limiting the generalizability of the findings to the general Korean population.

Conclusions

The findings suggest that Koreans undergoing COVID-19 quarantine are at higher risk of depression. While further investigation is warranted, public health measures to control infectious disease outbreaks, such as quarantine, would benefit from incorporating strategies to address unintended adverse psychological effects, such as depression.

Relationship Between Economic Loss and Anxiety During the Coronavirus Disease 2019 Pandemic: Moderating Effects of Knowledge, Gratitude, and Perceived Stress

OBJECTIVES

The prolonged coronavirus disease 2019 (COVID-19) pandemic has caused individuals to suffer economic losses, in particular due to the implementation of intensive quarantine policies. Economic loss can cause anxiety and has a negative psychological impact on individuals, worsening their mental health and satisfaction with life. We examined the protective and risk factors that can influence the relationship between economic loss and anxiety during the COVID-19 pandemic.

METHODS

Panel data from 911 participants were collected in April and May 2020 and again 6 months later. We analyzed the relationship between economic loss and anxiety and investigated the moderating effects of knowledge about COVID-19, gratitude, and perceived stress. Moreover, we investigated whether there were any changes in moderating effects over time or in different demographic groups.

RESULTS

In the early stages of the spread of COVID-19, gratitude (B = -0.0211, F = 4.8130, p < 0.05) and perceived stress (B = 0.0278, F = 9.3139, p < 0.01) had moderating effects on the relationship between economic loss and anxiety. However, after 6 months, only perceived stress had a significant moderating effect (B = 0.0265, F = 7.8734, p < 0.01).

CONCLUSION

In the early stages of COVID-19, lower levels of gratitude and higher perceived stress led to greater anxiety. In later stages of the prolonged pandemic, only perceived stress had a continued moderating effect on the relationship between economic loss and anxiety. This study suggests that psychological interventions to reduce perceived stress are needed to treat the possible adverse effects of the spread of infectious diseases on mental health.

The association of gratitude with perceived stress among nurses in Korea during COVID-19 outbreak

BACKGROUND

During the COVID-19 pandemic, nurses might experience added emotional stress. This study examined the relationship between gratitude and psychological stress to explore effective psychological support among nurses.

METHODS

A cross-sectional survey assessed the level of psychological distress in 646 nurses in Gwangju, South Korea, using the Perceived Stress Scale-10 (PSS-10), Gratitude Questionnaire-6 (K-GQ-6), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Maslach Burnout Inventory-General Survey (MBI-GS). Sociodemographic factors and COVID-19-related experiences were also examined. A linear regression model was used to determine the factors influencing perceived stress.

RESULTS

The mean PSS-10 score was 19.0 ± 4.4. Linear regression analyses revealed that the MBI-GS-Exhaustion, PHQ-9, and GAD-7 scores were positively associated with perceived stress, while the MBI-GS-Professional efficacy score was inversely associated with perceived stress. Gratitude disposition using the K-GQ-6 score negatively predicted PSS-10 (β = 0.829, p < 0.001).

CONCLUSIONS

Psychological interventions that help cultivate gratitude and professional efficacy among nurses can help promote stress resilience throughout the course of the COVID-19 pandemic.

COVID-19 Impact on Residential Preferences in the Early-Stage Outbreak in South Korea

In the early stage of the COVID-19 pandemic in South Korea, public fear or social scaring of urban living was observed, which caused people to change their daily routines. This study examines how the COVID-19 pandemic affected residential choice and perceptions of urban living. We analyzed self-reported survey data collected from 2000 participants in Seoul, Daegu, and Kyeongbuk in South Korea between 3-6 August 2020, targeting the relatively controlled period after the first COVID-19 outbreak. Logistic regression models were used to examine concerns of urban living and residence relocation consideration. Those who were aged 30 or older, regularly commuting, not feeling healthy, with a household size of two, and living in a low-rise condominium were more likely to be concerned with urban living. Those who were aged 40 or older and living in a townhouse or a single-detached house were more likely to consider moving to a less dense area. People perceived that their daily routine changed substantially after the pandemic. Certain participant groups showed concerns of urban living and relocation consideration, suggesting housing policy implications.

Risk and protective factors of depression in the general population during the COVID-19 epidemic in Korea

BACKGROUND

The risk of depression has risen in the general population during the COVID-19 epidemic. This study was conducted to explore risk and protective factors associated with depression among the general population uninfected by COVID-19.

METHODS

A cross-sectional study was conducted with 1,500 representative South Korean citizens aged 19-65 years through an anonymous online survey. Depression was defined as a Patient Health Questionnaire-9 score of 10 or higher. Other questionnaires included one measuring psycho-behavioural and social changes, and stress, due to COVID-19, a six-item version of the Gratitude Questionnaire (GQ-6), and a three-item version of the UCLA loneliness scale.

RESULTS

Of the 1492 participants not infected by COVID-19, 312 (20.9%) exhibited depression. Multiple logistic regression analysis revealed that depression was positively associated with COVID-19-related stress and psycho-behavioural variables such as disturbances in eating and sleeping, younger age, smoking, underlying mental illness, and loneliness scale scores. In contrast, exercise three or more times per week and GQ-6 scale scores were inversely associated with depression.

CONCLUSION

During the COVID-19 pandemic, maintaining daily routines including eating, sleeping, and regular exercise and focusing on gratitude may be important for the prevention of depression. In addition, more attention should be paid to vulnerable populations, including young people, those with mental illnesses, and smokers, who might be more susceptible to depression.

Overview of behavioural and psychological consequences of COVID 19

PURPOSE OF REVIEW

The paper aims to provide an overview of the psychological and behavioural impacts of the COVID-19 pandemic, with a focus on variations in behavioural response in different geographical areas due to the existence of different social-cultural contexts.

RECENT FINDINGS

Whilst anxiety, depression and economic stressors are common findings worldwide, specific behavioural responses are heavily influenced by government stances, misinformation, conspiratorialism and competing demands of resource scarcity. This has led to very different understandings of the pandemic even in geographically close areas, and more so when comparing disparate regions such as Africa, South America and Europe. The paper also comments on the absence of robust evidence regarding increases of suicidality and violence on a global level, whilst noting evidence certainly exists in specific regions.

SUMMARY

The psychological and behavioural impact of COVID is heavily influenced by the local lens. Beyond a very broad brush approaches, expected behaviours from one area cannot easily be extrapolated to others. Where possible, clinicians should be guided by local data, ideally placing expectations of responses in a cultural context.

Factors Associated With a Negative Emotional Response to News Media and Nationwide Emergency Text Alerts During the COVID-19 Outbreak in Korea

OBJECTIVE

To prevent the spread of infection in Korea during the corona virus disease 2019 (COVID-19) outbreak, real-time warnings have been sent to all residents via mobile phones. This study examined the factors associated with the negative emotional response to media news and emergency text alerts in the COVID-19 pandemic.

METHODS

A survey was completed by 1,500 adults from an online public panel in three regions. We used Patient Health Questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7) and Perceived Stress Scale-10 (PSS-10) to assess the level of depression, anxiety and stress, respectively. Questionnaires related to COVID-19 included fear of infection, and fear of disclose of contact-tracing information.

RESULTS

The negative emotional response on both news media information and emergency alert text messages about COVID-19 was associated with fear of COVID-19 infection and high anxiety. The biggest outbreak city, Daegu was associated with the less negative emotional response on emergency alert text messages. Fear of disclose of contact-tracing information was significantly associated with negative emotional perception on emergency alter text messages.

CONCLUSION

Our results suggest that effective information providing services with considering vulnerable groups are needed to promote acceptance and eliminate negative emotion for disease related information.

Psychological state, family functioning and coping strategies among undergraduate students in a Nigerian University during the COVID-19 lockdown

INTRODUCTION

The curtailment of social gatherings and the lack of online academic engagement during the COVID-19 lockdown could have potentially damaging effects on the psychological state of university students in Nigerian public universities. This study examined the prevalence of anxiety and depression, including associated factors and coping methods, among undergraduate students.

METHODS

This cross-sectional study, which involved 386 undergraduate students, was assigned approval number UI/EC/20/0242. An online questionnaire consisting mainly of the Hospital Anxiety and Depression Scale and the McMaster Family Assessment Device was circulated among the students. The results were analysed by means of descriptive statistics, chi-square, Analysis of Variance (ANOVA) and linear logistical regression, at α 0.05.

RESULTS

Mean age was 21 ± 2.9 years, with females constituting 60.1% of the sample. The prevalence rates of anxiety and depression were 41.5 and 31.9%, respectively. Students in health-related faculties were significantly less anxious than others. Inability to afford three square meals, negative family functioning, chronic illness and living in a State/Region with a high incidence of COVID-19 were significantly associated with depression. These factors jointly accounted for 14% of depression. Coping methods included the use of social media, watching movies and participating in online skills-development programs.

CONCLUSION

The overall level of anxiety and depression among undergraduate students during the COVID-19 lockdown was higher than the levels previously reported. Inadequate nutrition and poor family functioning contributed significantly to this. Proactive measures ought to be taken to support undergraduate students in order to prevent the negative consequences of poor mental health.

Covid-19, Lockdown and Self-Isolation: Evaluation of Deliberate Self-Harm Admissions

Background: COVID 19 is still presenting a clear and dynamic global threat. The United Kingdom remains one of the hardest hit countries from the pandemic. In January 2021 parliament announced that the UK will be entering a full national lockdown. This paper explores what effect lockdown measures had on rates of deliberate self-harm presentations to one NHS trust in Manchester UK. Methods: This paper compared the number of cases of deliberate self-harm which presented to the emergency department of Manchester Royal Infirmary for March-May in 2018, 2019 and 2020. This was achieved by utilising coding from emergency department data and reviewing hospital records surrounding each case. Results: 2018 recorded a total of 101 admissions as a result of DSH with all causes admissions of 8,514 making the proportions of admissions due to self-harm 1.19%. In 2019, 9,038 patients were admitted, of these, 130 (1.44%) were identified as DSH. In 2020 the total number of admissions fell to 5,676 with 118 admitted due to self-harm, representing 2.08% of admissions. The absolute number of admissions remained stable however the proportion of admissions due to self-harm was significantly higher in 2020 (p < 0.001). Other significant findings include a higher proportion of male admissions compared to females in 2020 (58.5%) and a decrease in the normal of cases relating to paracetamol overdose in 2020. Discussion: The findings demonstrated by this study do not indicate that lockdown is an absolute risk for DSH behaviours however it does illustrate the stable nature of these cases despite and dramatic decline in all cause admissions. The rate of increase of deliberate self-harm accelerated significantly between March and May in 2020. Steps must be taken to avoid a similar situation following the 2021 lockdown and beyond - focus on improving access to certain virtual services may help to achieve this goal.

The Relationships among Media Usage Regarding COVID-19, Knowledge about Infection, and Anxiety: Structural Model Analysis

BACKGROUND

We examined the effects of mass media usage on people's level of knowledge about coronavirus disease 2019 (COVID-19), fear of infection, prejudice towards infected people, and anxiety level. In addition, we investigated whether knowledge about COVID-19 can reduce fear, prejudice, and anxiety.

METHODS

We performed an anonymous online survey in 1,500 residents aged 19-65 years between April 24 and May 5 of 2020. Anxiety level was assessed using the generalized anxiety disorder-7 scale. We used a questionnaire to investigate COVID-19-related media use, knowledge about COVID-19, fear of infection, and prejudice towards infected people. We analyzed the relationships among the variables using the structural equation model.

RESULTS

Media use had significant effects on fear of infection, prejudice against infected people, and anxiety. Knowledge about COVID-19 had a significant protective effect on fear of infection, prejudice against infected people, and anxiety. However, the effect of media use on knowledge about COVID-19 was not statistically significant. There was a partial mediating effect of prejudice against infected people and fear of infection on media usage and anxiety.

CONCLUSION

Our study demonstrated significant effects of mass media coverage regarding COVID-19 on fear, prejudice, and anxiety. While knowledge about COVID-19 could decrease fear, prejudice, and anxiety, the use of mass media did not enhance this knowledge. Medical societies should guide mass media reporting of COVID-19 and provide appropriate public education.
