Objective: The study was conducted to investigate the impact of unrealistic optimism on the risk of contamination at home con nement and its association with certain social variables. Methods: This survey study was conducted to describe the level of unrealistic optimism and its association with some social variables. The participants (n = 558, 60.6% females and 39.4 males) subjectively evaluated the risk of their coronavirus infection in the period 1-15 May 2020, for this purpose a questionnaire was adopted and administered to a sample of 558 citizens. Results: the results showed that 69.2% of the participants con rmed their respect always, and 38.7% con rmed that they rarely wear the mask, while 24% of the sample con rmed that they only sometimes wear the mask when they leave the house, including 50.5% of the sample con rmed that people infected with the coronavirus suffer from social stigmatization. It is found that 54.8% of the respondents had an average level of unrealistic optimism, where the mean of participants was (36, 17 ± 5, 97). The study also revealed that there is an association between the levels of unrealistic optimism and respect the home con nement (P = 0.001); whereas, the results showed that there is no association between the levels of unrealistic optimism and wearing the mask (P = 0.183). The study discovered there is signi cantly a negative association (B =-, 119, P = 0.005) between unrealistic optimism and the age of Algerian citizens during the home con nement of coronavirus. Otherwise, while the results did not show any statistically signi cant differences in unrealistic optimism between groups of gender among Algerian citizens during the home con nement of coronavirus (P = 0, 0835). Conclusions: In effect, unrealistic optimism is linked to avoiding risky behaviors that threaten human life as it is the case with the coronavirus. Therefore, it is important to reduce the levels of unrealistic optimism of individuals with beliefs and objective information to avoid dangerous behavior during and after the con nement period.

BackgroundHealthcare workers fighting against the coronavirus disease 2019 (COVID-19) pandemic are under tremendous pressure, which puts them at an increased risk of developing psychological problems.AimsThis study aimed to investigate the prevalence of psychological problems in different healthcare workers (ie, physicians, medical residents, nurses, technicians and public health professionals) during the COVID-19 pandemic in China and explore factors that are associated with the onset of psychological problems in this population during this public health crisis.MethodsA cross-sectional, web-based survey was conducted in February 2020 among healthcare workers during the COVID-19 pandemic. Psychological problems were assessed using the Generalized Anxiety Disorder Scale, Patient Health Questionnaire and Insomnia Severity Index. Logistic regression analyses were used to explore the factors that were associated with psychological problems.ResultsThe prevalence of symptoms of anxiety, depression, insomnia and the overall psychological problems in healthcare workers during the COVID-19 pandemic in China was 46.04%, 44.37%, 28.75% and 56.59%, respectively. The prevalence of the overall psychological problems in physicians, medical residents, nurses, technicians and public health professionals was 60.35%, 50.82%, 62.02%, 57.54% and 62.40%, respectively. Compared with healthcare workers who did not participate in front-line work, front-line healthcare workers had a higher risk of anxiety, insomnia and overall psychological problems. In addition, attention to negative or neutral information about the pandemic, receiving negative feedback from families and friends who joined front-line work, and unwillingness to join front-line work if given a free choice were three major factors for these psychological problems.ConclusionsPsychological problems are pervasive among healthcare workers during the COVID-19 pandemic. Receiving negative information and participating in front-line work appear to be important risk factors for psychological problems. The psychological health of different healthcare workers should be protected during the COVID-19 pandemic with timely interventions and proper information feedback.

Background and ObjectivesThe COVID‐19 pandemic and control measures may have increased the risk of abusing addictive substances as well as addictive behaviors.MethodsWe present an initial online survey in 6416 Chinese about the relation between the COVID‐19 pandemic and addictive behavior in China.ResultsDuring the COVID‐19 pandemic, 46.8% of the subjects reported increased dependence on internet use, and 16.6% had longer hours of internet use. The prevalence (4.3%) of severe internet dependence rose up to 23% than that (3.5%) before the COVID‐19 pandemic occurred, and their dependence degree rose 20 times more often than being declined (60% vs 3%). Relapses to abuse from alcohol and smoking abstinence were relatively common at 19% and 25%, respectively. Similarly, 32% of regular alcohol drinkers and 20% of regular smokers increased their usage amount during the pandemic.Conclusion and Scientific SignificanceThese three coping behaviors (internet, alcohol, and smoking) during this COVID‐19‐related crisis appear to have increased the risk for substance use disorders and internet addiction.

Quarantine and isolation measures urgently adopted to control the COVID-19 pandemic might potentially have negative psychological and social effects. We conducted this cross-sectional, nationwide study to ascertain the psychological effect of quarantine and identify factors associated with mental health outcomes among population quarantined to further inform interventions of mitigating mental health risk especially for vulnerable groups under pandemic conditions. Sociodemographic data, attitudes toward the COVID-19, and mental health measurements of 56,679 participants from 34 provinces in China were collected by an online survey from February 28 to March 11, 2020. Of the 56,679 participants included in the study (mean [SD] age, 36.0 [8.2] years), 27,149 (47.9%) were male and 16,454 (29.0%) ever experienced home confinement or centralized quarantine during COVID-19 outbreak. Compared those without quarantine and adjusted for potential confounders, quarantine measures were associated with increased risk of total psychological outcomes (prevalence, 34.1% vs 27.3%; odds ratio [OR], 1.34; 95% CI, 1.28-1.39; P < 0.001). Multivariable logistic regression analyses showed that vulnerable groups of the quarantined population included those with pre-existing mental disorders or chronic physical diseases, frontline workers, those in the most severely affected areas during outbreak, infected or suspected patients, and those who are less financially well-off. Complying with quarantine, being able to take part in usual work, and having adequate understanding of information related to the outbreak were associated with less mental health issues. These results suggest that quarantine measures during COVID-19 pandemic are associated with increased risk of experiencing mental health burden, especially for vulnerable groups. Further study is needed to establish interventions to reduce mental health consequences of quarantine and empower wellbeing especially in vulnerable groups under pandemic conditions.

Background Coronavirus disease 2019 (COVID-19) has evolved into a worldwide pandemic, and has been found to be closely associated with mental and neurological disorders. We aimed to comprehensively quantify the association between mental and neurological disorders, both pre-existing and subsequent, and the risk of susceptibility, severity and mortality of COVID-19. Methods In this systematic review and meta-analysis, we searched PubMed, Web of Science, Embase, PsycINFO, and Cochrane library databases for studies published from the inception up to January 16, 2021 and updated at July 7, 2021. Observational studies including cohort and case-control, cross-sectional studies and case series that reported risk estimates of the association between mental or neurological disorders and COVID-19 susceptibility, illness severity and mortality were included. Two researchers independently extracted data and conducted the quality assessment. Based on I 2 heterogeneity, we used a random effects model to calculate pooled odds ratios (OR) and 95% confidence intervals (95% CI). Subgroup analyses and meta-regression analysis were also performed. This study was registered on PROSPERO (registration number: CRD 42021230832). Finding A total of 149 studies (227,351,954 participants, 89,235,737 COVID-19 patients) were included in this analysis, in which 27 reported morbidity (132,727,798), 56 reported illness severity (83,097,968) and 115 reported mortality (88,878,662). Overall, mental and neurological disorders were associated with a significant high risk of infection (pre-existing mental: OR 1·67, 95% CI 1·12-2·49; and pre-existing neurological: 2·05, 1·58-2·67), illness severity (mental: pre-existing, 1·40, 1·25-1·57; sequelae, 4·85, 2·53-9·32; neurological: pre-existing, 1·43, 1·09-1·88; sequelae, 2·17, 1·45-3·24), and mortality (mental: pre-existing, 1·47, 1·26-1·72; neurological: pre-existing, 2·08, 1·61-2·69; sequelae, 2·03, 1·66-2·49) from COVID-19. Subgroup analysis revealed that association with illness severity was stronger among younger COVID-19 patients, and those with subsequent mental disorders, living in low- and middle-income regions. Younger patients with mental and neurological disorders were associated with higher mortality than elders. For type-specific mental disorders, susceptibility to contracting COVID-19 was associated with pre-existing mood disorders, anxiety, and attention-deficit hyperactivity disorder (ADHD); illness severity was associated with both pre-existing and subsequent mood disorders as well as sleep disturbance; and mortality was associated with pre-existing schizophrenia. For neurological disorders, susceptibility was associated with pre-existing dementia; both severity and mortality were associated with subsequent delirium and altered mental status; besides, mortality was associated with pre-existing and subsequent dementia and multiple specific neurological diseases. Heterogeneities were su...

Background and Objectives COVID‐19‐related quarantine and stress have likely escalated the crisis of Internet addiction. This study aimed to determine the impact of the COVID‐19 pandemic on Internet use and related risk factors among the general public in China. Methods A large‐sample cross‐sectional online survey was conducted from March 24 to April 30, 2020, in China, and 20,472 participants completed the survey. We investigated the prevalence and severity of Internet addiction based on the Internet Addiction Test (IAT), and explored the risk factors related to increases in time spent on Internet use and severity of Internet addiction, as well as severe Internet addiction. Results The overall prevalence of Internet addiction was 36.7% among the general population during the pandemic, and that of severe Internet addiction was 2.8%, according to IAT scores. Time spent on recreational Internet use had significantly increased during the pandemic, and almost half of participants reported increases in the severity of Internet addiction. Risk factors for increases in time spent on Internet use and severity of Internet addiction and severe Internet addiction included having fewer social supporters, perceiving pressure and impact on mental health status due to COVID‐19, and being over‐engaged in playing videogames. Discussion and Conclusions The COVID‐19 pandemic adversely impacted Internet use and increased the prevalence and severity of Internet addiction among the general population in China, especially in vulnerable populations. Scientific Significance This study provides evidence for policymakers to refine public health policies to control the pandemic and make efforts to provide population‐specific prevention and interventions for people at risk of developing Internet addiction.
