Intolerance of COVID-19-related uncertainty and depressive and anxiety symptoms during the pandemic: A longitudinal study in Argentina

Longitudinal network analysis of depression, anxiety, and post-traumatic stress disorder comorbidities among adolescents in regional China

Purpose

The network theory of mental disorders offers a new perspective for the understanding of comorbidities, but the research on the comorbidities among depression, anxiety, and post-traumatic stress disorder (PTSD) is still insufficient. The aim of this study was to explore the internal relationship by establishing and analyzing the comorbidity networks, and to provide suggestions for the intervention after traumatic events.

Methods

We utilized data from the second and third wave of the Chengdu Positive Child Development cohort (N = 3,189, 47.79% female), we estimated to network models of depression, anxiety and PTSD. To assess difference in global connectivity between the two networks, we conducted invariance test.

Results

K27 (Somatic 10), K37 (Generalized Anxiety 9), K15 (Somatic 5), K33 (Generalized Anxiety 7), K24 (Somatic 9) were the most central nodes in both networks, P13 (Sleep problem) had the highest Bridge Expected Influence value. The structural difference between the two networks was statistically significant (M = 0.229, p = 0.010), and the global strength of the network at wave 2 was higher than the network at wave 3 (35.1 vs. 33.9, S = 1.20, p = 0.010).

Conclusion

The correlation in symptoms of the three disorders underscores the need for more comprehensive treatment options for intervention after traumatic events. Central and bridge nodes could inform targeted interventions or policy decisions. Anxiety disorders, especially Som and Gen dimensions, should be the focus of intervention. The Arousal dimension in PTSD, especially sleep disorders, may contribute to the comorbidities. In addition, this study highlights the importance of staged post-traumatic interventions.

Depression and anxiety in the context of the COVID-19 pandemic: A 6-waves longitudinal study in the Argentine population

PURPOSE

The pandemic has caused stress due to isolation, loss of loved ones, work and learning changes, financial instability, fear of infection, and uncertainty. It has negatively impacted mental health, particularly increasing anxiety, and depression symptoms. This study analyzed anxiety and depression symptoms over the first 25 months of the COVID-19 pandemic, considering age group, socioeconomic status, and gender.

METHODS

A longitudinal study with 6 repeated measures was conducted, involving 988 adult participants from Argentina. Adapted versions of the BDI-II and STAI were administered through online questionnaires at 2, 14, 50, 130, 390, and 750 days since the start of the lockdown.

RESULTS

The results showed a sustained increase in anxiety and depression symptoms up to 390 days, followed by a decrease in anxiety below initial levels at 750 days. Depressive symptoms significantly decreased after 750 days but remained higher than initial levels.

CONCLUSION

Women consistently scored higher than men, lower socioeconomic status individuals reported more symptoms, and younger individuals had higher anxiety and depression, which decreased with age. Surprisingly, older individuals displayed better mental health indicators compared to the rest of the population.

Intolerance of uncertainty, aging, and anxiety and mental health concerns: A scoping review and meta-analysis

Although intolerance of uncertainty (IU) is associated with negative outcomes, studies focusing on older adults are still emerging. Specifically, the relationship between IU and psychological health in this population remains unclear. Moreover, no review has focused on understanding the unique contributions of IU and aging to anxiety and mental health in older adults. This scoping review and meta-analysis addressed this gap and provided a comprehensive understanding of the relationship between IU, aging, and mental health. Among 45 studies reviewed, 37 were included in the meta-analysis using mixed effect analysis to examine the relationship between IU and age across adulthood. The remaining eight studies, along with seven selected from the meta-analysis, were included in the scoping review to evaluate the relationship between IU, anxiety, and mental health. Among these, 12 studies focused on late adulthood, two on overall adulthood, and one included both late and overall adulthood. Results of the meta-analysis revealed an overall significant age difference in IU throughout adulthood. Moreover, results of the scoping review indicated a direct correlation between IU and anxiety, and other psychological issues in elderly. These findings provide insights for future research and interventions aimed at reducing IU and improving mental health among older adults.

Mental health indicators in pharmaceutical sciences students during the COVID-19 pandemic

INTRODUCTION

The COVID-19 pandemic changed the daily lives of university students and affected their mental health. The aim of this study was to assess the feelings and perceptions regarding the pandemic and teaching, and to identify the mental health symptoms perceived by pharmaceutical sciences students at a Brazilian public university.

METHODS

This is a cross-sectional study with data triangulation (mixed-methods approach), conducted online with semiannual data collection from May 2020 to May 2021. The Depression, Anxiety, and Stress Scale (DASS-21) and 4 open-ended questions (concerns and perceptions about education and feelings during the pandemic) were used. To identify key indicators of mental health symptoms a network analysis was conducted. The qualitative data were analyzed by similarity and collective subject discourses methods.

RESULTS

There were 682 responses to the study (phase 1: n = 153; phase 2: n = 254; phase 3: n = 275). Most of them were female (67.0-77.8 %) and reported symptoms of anxiety (89.5-93.3 %), distress (72.5-76.3 %), fear (58.8-71.6 %), and insomnia (66.5-72.4 %). The DASS-21 indicators: "I found myself getting agitated," "I felt downhearted and blue" and "I felt that life was meaningless" had greater strength for maintaining the network. Among self-reported symptoms, tachycardia was the network central node. The students raised topics about mental health, teaching, uncertainties, and health protocols and three concerns were health, college, and COVID-19.

CONCLUSION

There was a high prevalence of mental health symptoms among students. The disruption of the relationship system, instructional model, and future expectations may have influenced this prevalence.

Real-world predictors of severe psychological distress during the COVID-19 pandemic in Japan: Insights from a large-scale internet-based cohort study

AIM

The COVID-19 pandemic has had negative physical and psychological impacts worldwide. However, there has been a lack of real-world evidence concerning the predictors of severe psychological distress (SPD) among the general population in Japan during the COVID-19 pandemic. The aim of this study was to examine predictors of SPD during the COVID-19 pandemic.

METHODS

We investigated the predictors of new-onset SPD in the general Japanese population using data from a large-scale internet-based cohort study.

RESULTS

We included 16 489 study participants (age range = 16-81, mean age = 52.7, percentage of male = 50%) in the analysis. Over the course of 1 year from baseline, the estimated proportion of participants who experienced SPD was 5.2% with inverse probability weighting. The predictors of SPD included younger age, being never married, being unemployed, having a higher education background, scoring higher on the Fear of Coronavirus-19 Scale, experiencing more adverse childhood experiences, reporting poorer subjective health status, and COVID-19 with oxygen therapy. Our internet-based survey of the Japanese population may have selection bias, limiting the generalizability to other countries and cultures.

CONCLUSION

This study revealed that being afflicted with COVID-19 requiring oxygen therapy is the most significant predictor of SPD. In addition, we found that vulnerability to social isolation, such as never being unmarried, anxiety toward COVID-19, and susceptibility to stress, are predictors of the emergence of SPD. Therefore, the implementation of online support systems and ensuring access to accurate information may protect against SPD during the COVID-19 pandemic in Japan.

Effect of a smartphone-based physical intervention on depression, fitness factors and movement characteristics in adults

BACKGROUND

Physical activity has been shown to correlate with mental health and a reduction in symptoms of depression. However, the majority of research has focused only on the effects of either aerobic or nonaerobic exercise on depressive symptoms, while the use of novel technological innovations such as mobile phone-based activity programs and their effects on movement characteristics are underrepresented. This study had two objectives: (1) to investigate how effectively 4 weeks of mobile phone-based physical activity can affect depressive scores (CES-10-D and PHQ) and fitness levels and (2) to investigate the whether 4 weeks of mobile phone-based physical activity affected participants' movement characteristics.

METHODS

A total of 31 participants were included and divided into an exercise group (n = 21) and a control group (n = 10). The exercise group was instructed to use a mobile phone-based exercise program 5 times per week for 4 weeks. Pre- and post-exercise, the participants' depression score (CES-10-D, PHQ9), fitness level (YMCA, grip strength) and movement characteristics (postural sway, movement ROM, movement speeds, etc.) for three Azure Kinect physical activity games based on different fitness factors (balance game, cardiovascular game, reaction game) were measured.

RESULTS

Mixed model ANOVA revealed significant differences between pre- and post-intervention depression scores on the PHQ9 (P = .001) and CES-10-D (P < .001) in both the exercise group and the control group, but not between groups. In terms of movement characteristics, there was an increase in body sway (P = .045) and vertical head movement (P = .02) in the cardiovascular game jogging condition for the exercise group. In the reaction game, the exercise group showed a significant reduction in the number of mistakes (P = .03). There were no other significant differences for the other variables.

CONCLUSION

The results revealed no differences in the reduction in depression scores between the exercise group and the control group. However, this study showed that a mobile phone-based physical activity intervention affects in-game movement characteristics such as body sway and vertical head movement and therefore may show the potential of using activity-promoting mobile games for improving movement.

The association between intolerance of uncertainty and depressive symptoms during COVID-19 in New York, USA

BACKGROUND

Coronavirus Disease 2019 (COVID-19), a highly contagious respiratory illnesses, has globally impacted mental health. This study aims to investigate the association between intolerance of uncertainty and depressive symptoms during the pandemic in New York, USA, considering COVID-19-related worries as modifiers and mediators.

METHOD

1227 participants from three ongoing cohort studies, originally centered on trauma-exposed children and adolescents, provided data via questionnaires and telephone interviews across three waves. We used multivariable logistic and linear regression models to investigate the intolerance of uncertainty-depressive symptoms relationship, while adjusting for potential confounders and assessing the modification and mediation effects of Covid-19 related worries.

RESULTS

Depressive symptoms prevalence was 18 %, 12 %, and 9 % at waves 0, 1, and 2 respectively. Strong positive associations were observed between intolerance of uncertainty above the median and depressive symptoms which remained significant after adjusting for potential confounders. Odds ratios were 2.14 (95 % CI: 1.54-2.99) and 4.50 (95 % CI: 2.67-7.93) for intolerance of uncertainty-depressive symptoms association at wave 0 and 1 respectively, and 3.22 (95 % CI: 1.68-6.63) for intolerance of uncertainty at wave 1 and depressive symptoms at wave 2. There was evidence of partial mediation by worries (12-37 %), but no evidence of a moderating effect.

LIMITATION

It includes study's methodology, including self-report measures, remote data collection, and uncontrolled variables like anxiety and COVID-19 perspectives.

CONCLUSION

The findings emphasize the importance of evidence-based strategies for tackling intolerance of uncertainty during pandemics, particularly in managing long COVID. Collaborative efforts between policymakers and clinicians are essential in this endeavor.

Impact of Stress during COVID-19 Pandemic in Italy: A Study on Dispositional and Behavioral Dimensions for Supporting Evidence-Based Targeted Strategies

The COVID-19 pandemic caused critical mental health issues and lifestyle disruptions. The aim of this study was to explore, during the lockdown of second-wave contagions in Italy, how stress was affected by dispositional (personality factors and intolerance to uncertainty) and behavioral (coping strategies) dimensions, how these variables differed among sex, age, educational, professional, and health groups, and how the various changes in work and daily routine intervened in the psychological impact of the emergency. Our results highlight that women, the youngs, students/trainees, those with chronic diseases, those who stopped their jobs due to restrictions, and those who left home less than twice a week were more stressed, while health professionals showed lower levels of the same construct. Those with higher levels of stress used more coping strategies based on avoidance, which positively correlated with age, agreeableness, conscientiousness, and intolerance to uncertainty, and negatively with openness. Stress levels also positively correlated with agreeableness, conscientiousness, intolerance to uncertainty, and seeking of social support, and negatively with openness, a positive attitude, and a transcendent orientation. Finally, stress was predicted mainly by behavioral dimensions. Our results are discussed and framed within the literature, as important insights for targeted intervention strategies to promote health even in emergencies.

The moderated-mediation role of risk perception and intolerance of uncertainty in the association between residual symptoms and psychological distress: a cross-sectional study after COVID-19 policy lifted in China

BACKGROUND

A considerable number of individuals infected with COVID-19 experience residual symptoms after the acute phase. However, the correlation between residual symptoms and psychological distress and underlying mechanisms are scarcely studied. We aim to explore the association between residual symptoms of COVID-19 and psychological distress, specifically depression, anxiety, and fear of COVID-19, and examine the role of risk perception and intolerance of uncertainty in the association.

METHODS

A cross-sectional survey was conducted by online questionnaire-based approach in mid-January 2023. Self-reported demographic characteristics, COVID-19-related information, and residual symptoms were collected. Depression, anxiety, fear, risk perception and intolerance of uncertainty were evaluated using the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Fear of COVID-19 Scale (FCV-19S), COVID-19 Risk Perception Scale and Intolerance of Uncertainty Scale-12 (IUS-12), respectively. Linear regression analyses were conducted to explore the associations. A moderated mediation model was then constructed to examine the role of risk perception of COVID-19 and intolerance of uncertainty in the association between residual symptoms and psychological distress.

RESULTS

1735 participants effectively completed the survey. 34.9% of the patients experienced residual symptoms after acute phase of COVID-19. Psychological distress was markedly increased by COVID-19 infection, while residual symptoms had a significant impact on psychological distress (Ps < 0.001), including depression (β = 0.23), anxiety (β = 0.21), and fear of COVID-19 (β = 0.14). Risk perception served as a mediator between residual symptoms and all forms of psychological distress, while intolerance of uncertainty moderated the effect of risk perception on depression and anxiety.

CONCLUSION

A considerable proportion of patients experience residual symptoms after acute phase of COVID-19, which have a significant impact on psychological distress. Risk perception and intolerance of uncertainty play a moderated-mediation role in the association between residual symptoms and depression/anxiety. It highly suggests that effective treatment for residual symptoms, maintaining appropriate risk perception and improving intolerance of uncertainty are critical strategies to alleviate COVID-19 infection-associated psychological distress.

Consequences of COVid-19 in Latin American dentists in the first year of the pandemic, the period prior to vaccination campaigns

Objectives

The aim of this investigation was to assess the impact of the COVID-19 pandemic on dentists in Latin America during the initial year of the outbreak, specifically within the timeframe preceding vaccination campaigns. This study determined the various facets in which dentists were affected and exactly what proportion of them was harmed.

Methods

A comprehensive 33 question survey was distributed across 19 Latin American countries after the first year of the COVID-19 pandemic's presence in the region.

Results

There was an absence of statistically significant differences in responses among the surveyed countries in Latin America, with the exception of four questions out of the total 33. Some relevant findings of Latin American were: one in three dental professionals experienced discrimination based on their occupation. Concurrently, three out of four dentists reported initiating new activities to lessen discomfort. Notably, 8.63 % of respondents sought assistance from a psychologist or psychiatrist, while 17.71 % resorted to the consumption of psychoactive substances within the first year of the pandemic.Furthermore, 7.28 % of the professionals indicated that they still had not obtained all the necessary personal protective equipment for their work and 92.05 % disclosing that they personally financed these essential resources. A certain percentage of dentists stated that the quality of care decreased due to the implementation of the new safety measures (40.03 %) or due to their own feelings during patient interactions (23.11 %). Lastly, 38.85 % of dentists contemplated leaving the profession.

Conclusions

The impact of the COVID-19 pandemic on dentists was decidedly adverse, manifesting both in personal and professional fields, despite the diverse measures undertaken by these professionals to mitigate its effects.

Pandemic fatigue and depressive symptoms among college students in the COVID-19 context: indirect effects through sense of control and intolerance of uncertainty

Pandemic fatigue, the state of weariness, exhaustion, and demotivation to engage in protective behaviors during the coronavirus disease 2019 (COVID-19) pandemic, have been linked with depressive symptoms. However, the mechanism underlying this association remains unclear. Based on the stress process model, the present study examined the indirect effects of pandemic fatigue on depressive symptoms through the indirect roles of sense of control and intolerance of uncertainty. Data were collected from 1,162 Chinese undergraduate and postgraduate students (Mage = 21.61 years old, SD = 2.81, 64.29% women) through electronic questionnaires. The pandemic fatigue scale, the personal mastery scale, the short version of the Intolerance of Uncertainty Scale, and the Depression subscale of the Depression-Anxiety-Stress Scales were employed. Indirect effects were analyzed using structural equation modeling. The results revealed that pandemic fatigue related to COVID-19 was positively associated with depressive symptoms through (a) sense of control; (b) intolerance of uncertainty; and (c) a sequential pathway from sense of control to intolerance of uncertainty. The findings expand the application of the stress process model to the context of COVID-19 and deepen the understanding of pandemic fatigue-depressive symptoms link with considering the indirect roles of sense of control and intolerance of uncertainty. Psychological distress in the context of COVID-19 could be alleviated by the interventions on strengthening sense of control and tolerance of uncertainty and lessening the adverse effects of pandemic fatigue.

Impact of Intolerance of Uncertainty on Depression in College Students During the COVID-19 Pandemic: Coping Strategies as Mediators

The coronavirus disease (COVID-19) pandemic and associated infection control measures have introduced significant uncertainty, and the unbearable nature of this uncertainty has heightened the risk of mental health issues among college students. This study aimed to assess the impact of unbearable uncertainty during the COVID-19 pandemic on college students' depression and investigate the mediating role of coping strategies between unbearable uncertainty and depression. A cross-sectional survey was conducted with 714 Chinese university students using the Intolerance of Uncertainty Scale (IUS-12), Brief Coping Style Questionnaire, and Beck Depression Inventory (BDI-II). SPSS PROCESS was used for the partial correlation analyses and structural equation modeling. (1) Negative coping strategies were significantly positively correlated with intolerable uncertainty and depressive symptoms, while positive coping strategies were negatively correlated with both intolerable uncertainty and depressive symptoms. Intolerable uncertainty was significantly and positively correlated with depressive symptoms. (2) Intolerance to uncertainty significantly predicted depressive symptoms. Both negative and positive coping strategies played parallel mediating roles in the relationship between unbearable uncertainty and depressive symptoms among college students. This study found that coping strategies played a mediating role in the relationship between unbearable uncertainty and depression during the pandemic in 2019. Future research and interventions should focus on enhancing tolerance of uncertainty and promoting positive coping strategies.

Profiles of Intolerance of Uncertainty Among 108,540 Adolescents: Associations with Sociodemographic Variables and Mental Health

Intolerance of uncertainty (IU) is widely considered a transdiagnostic risk and maintaining factor for psychiatric disorders. However, little is known about the overall nature and profile of IU among adolescents. This study aims to investigate the profiles of IU among Chinese adolescents and explore their associations with sociodemographic characteristics and mental health problems. A sample of 108,540 adolescents provided data on IU, sociodemographic characteristics, and mental health via an online platform. Latent profile analysis revealed three profiles: Low IU, Medium IU, and High IU. Girls, older adolescents, and those with specific sociodemographics were more likely to belong to the "High IU" profile. Furthermore, the "High IU" profile was associated with the highest risk of several mental health problems. These findings provided valuable information for early prevention and intervention strategies targeting IU and highlighted the importance of IU-based interventions for mental health among adolescents.

Parenting, Gender, and Perception of Changes in Children's Behavior during the COVID-19 Pandemic

In a previous Argentine study, we found that, in the critical context of social isolation during the COVID-19 pandemic, there were changes in maternal practices that influenced the relationship with their children. We also found that the impact of mandatory isolation was moderated positively by protective factors such as positive parenting and maternal school support or negatively by risk factors such as maternal stress. Although this study only analyzed maternal behavior, we were interested in studying the behavior of both parents, comparing the parenting (positive parenting, parental stress, and school support) of the father and mother and the perceived behavioral changes in their children. A quantitative ex post facto study was carried out. The sample consisted of 120 Argentinean parents (70 mothers and 50 fathers) aged between 27 and 56 (M = 38.84; SD = 5.03). Questionnaires were administered on sociodemographic and behavioral data of the children, as well as a brief scale to assess parenting. Mann-Whitney U and MANOVA were used to analyze the influence of gender on perceived changes in children's behavior and perceived parenting, respectively. Mothers perceived more significant changes than fathers in their children's behavior. In addition, women reported more parental stress, greater child school support, and greater perceived positive parenting compared to men. These findings support the hypothesis that parenting developed differently in fathers and mothers. These results imply the need for psycho-educational intervention programs aimed at promoting greater involvement of fathers in parenting and better management of parental stress in mothers' and family psychological well-being.

Intolerance of uncertainty across stress, anxiety, and depression among university students in Pakistan: A descriptive cross-sectional study

BACKGROUND

The mental health issues due to COVID-19, such as intolerance of uncertainty (IOU), anxiety, stress, and depression, have attracted extensive attention from researchers. The challenges for Pakistani university students could be worse than developed countries due to the lack of online courses/programs and online mental health support provided by academic institutions. Therefore, the current study aims to assess the intolerance of uncertainty, depression, anxiety, and stress of Pakistani university students after the second wave of COVID-19 and the relationship among these constructs.

METHODS

A convenience cross-sectional sampling method was used to collect data from university students in Pakistan between January 2021 and April 2022 via a structured online questionnaire. The Descriptive analysis focused on frequencies, percentages, mean, and standard deviation (SD) were calculated on IOU-12 and DASS-21. Covariance for the research model and confirmatory factor analyses fit indices for the IOU-12 and DASS-21 were analyzed by AMOS statistical packages.

RESULTS

As expected, anxiety, depression, and stress persist among Pakistani university students. On average, they report mild to moderate mental health problems regarding anxiety, depression, stress, and intolerance of uncertainty. Our results indicate a strong positive relationship among the three emotional distress components - anxiety, depression, and stress. However, our results suggest no significant relationship between IOU and the three subcomponents of emotional distress (anxiety, depression, and stress).

LIMITATIONS

First, the cross-sectional survey design means we cannot conclude on the causal relations. Second, the self-report questionnaire embeds subjectivity issues. Last, the generalizability of the sample to the whole student population in Pakistan is limited, considering the sampling method.

CONCLUSION

This study expanded the current knowledge in the psychological health domain (intolerance of uncertainty, anxiety, depression, and stress) due to the COVID-19 pandemic. In practice, higher education institutions should further mitigate university students' mental health issues. For researchers, our findings inspire future studies to delve into the relationship between IOU and mental health issues due to COVID-19 since our findings display contrary evidence for various reasons.

The Causal Role of Lockdowns in COVID-19: Conclusions From Daily Epidemiological, Psychological, and Sociological Data

Much has been written about the COVID-19 pandemic's epidemiological, psychological, and sociological consequences. Yet, the question about the role of the lockdown policy from psychological and sociological points of view has not been sufficiently addressed. Using epidemiological, psychological, and sociological daily data, we examined the causal role of lockdown and variation in morbidity referring to emotional and behavioral aspects. Dynamics of support requests to the Sahar organization concerning loneliness, depression, anxiety, family difficulties, and sexual trauma were investigated alongside processes of emergency and domestic violence reports to the Ministry of Welfare and Social Affairs. By exploring the signals and predictive modeling for a situation with no lockdown implementation, the lockdown was found as a critical factor in distress rising among the general population, which could affect long after the improvement in pandemic case counts. Applications and implications are discussed in the context of decision-making in dealing with crises as well as the need to allocate resources for adaptive coping.

Trait Emotional Intelligence and Self-regulated Learning in University Students during the COVID-19 pandemic: the mediation role of Intolerance of Uncertainty and COVID-19 Perceived Stress

The coronavirus pandemic strongly impacted the higher education system, challenging university students, who were required to make a considerable effort in terms of revising their personal study approach and managing their emotions. The present study aimed to examine the impact of Trait Emotional Intelligence (TEI) on Self-Regulated Learning (SRL) strategies directly, and indirectly through the mediation of COVID-19 perceived stress (PS) and Intolerance of Uncertainty (IU). 1055 Italian university students (mean age = 22.44 years, SD = 2.39) reached via social media, filled out the tools assessing TEI, COVID-19 PS, IU and SRL. Five mediation analyses performed with PROCESS showed that TEI positively predicted all SRL dimensions, and negatively influenced COVID-19 PS and Prospective and Inhibitory IU. COVID-19 PS and Inhibitory and Prospective IU differently predicted specific SRL dimensions. The indirect effects observed suggest that TEI may help university students to cope with stressful and uncertain psychological experiences in order to achieve higher levels of SRL strategies. The study highlights that TEI plays a pivotal role in academic SRL strategies, underlining the importance of its buffering effect in distressing circumstances such as the COVID-19 pandemic.

Nonlinear effects of pandemic uncertainty on depression, pandemic preventive behavior intentions, and positive life attitudes: Moderating effects of high and low uncertainty grouping

Backgrounds

COVID-19 is difficult to end in a short time and people are still facing huge uncertainties. Since people's lives are gradually returning to normal, the sense of control and intolerance of uncertainty, which were mainly focused by past studies, are not specific to COVID-19 and will be more influenced by some factors unrelated to the pandemic. Therefore, they may be difficult to accurately reflect the individuals' perceptions of uncertainty. Besides, past research just after the outbreak mainly investigated people in high levels of uncertainty, we don't know the impact of uncertainties on individuals' psychological states when people gradually recovered their sense of control. To solve these problems, we proposed the concept of "pandemic uncertainty" and investigated its impact on people's daily lives.

Methods

During October 20, 2021 to October 22, 2021, this study obtained data about uncertainty, depression, positive attitude, pandemic preventive behavior intentions, personality, and social support from 530 subjects using convenient sampling. The subjects were all college students from the Dalian University of Technology and Dalian Vocational and Technical College. According to the distribution of uncertainty, we divided the dataset into high and low groups. Subsequently, by using uncertainty as the independent variable, the grouping variable as the moderating variable, and other variables as the control variables, the moderating effects were analyzed for depression, positive attitude, and pandemic preventive behavior intentions, respectively.

Results

The results showed that the grouping variable significantly moderate the influence of uncertainty on positive attitude and pandemic preventive behavior intentions but had no significant effect on depression. Simple slope analysis revealed that high grouping uncertainty significantly and positively predicted positive attitude and pandemic preventive behavior intentions, while low grouping effects were not significant.

Conclusion

These results reveal a nonlinear effect of pandemic uncertainty on the pandemic preventive behavior intentions and positive life attitudes and enlighten us about the nonlinear relationship of psychological characteristics during a pandemic.

Intolerance of uncertainty, anxiety sensitivity, and health anxiety during the COVID-19 pandemic: Exploring temporal relationships using cross-lag analysis

Intolerance of uncertainty (IU) and anxiety sensitivity (AS) have been widely discussed and explored as factors that may contribute to health anxiety. We propose that IU and AS are salient issues for many during the COVID-19 pandemic, and may play a role in the development or exacerbation of health anxiety during the pandemic. Studies have examined links between IU and AS with health anxiety during the pandemic, but these relationships have not been tested together using a longitudinal study design. In the present study, measures of IU, AS, and health anxiety were collected from 301 adults at two time points 6 months apart during (early stages of) the COVID-19 pandemic using an online survey platform. Cross-lagged analysis was utilized to simultaneously estimate cross-sectional and longitudinal associations between these three variables. Robust cross-sectional associations were observed, and IU prospectively predicted changes in both health anxiety and AS. No other statistically significant prospective associations emerged. Present findings support the putative role of IU in health anxiety, suggesting that some observed links between AS and health anxiety could be driven by shared variance with IU. IU may be an important factor to monitor and target in health anxiety interventions during the pandemic.

Anxiety among older adults during the COVID-19 pandemic

A growing body of research examines the COVID-19 pandemic's effects on well-being. Only few studies focus on older adults or explore the predictors of COVID-19-related anxiety. Intolerance of uncertainty (IU) and some behaviors (e.g., avoidance, procrastination) are linked to anxiety among older adults and could both be relevant to consider in a pandemic context. This study measured the occurrence and anxiety levels among older adults and verified the possible role of IU and behaviors in predicting anxiety symptoms, impairment and distress related to COVID-19 health standards. It also examined the indirect effect of IU on symptoms, impairment and distress through behaviors. Participants aged 60 and over (N = 356) were recruited and administered questionnaires. Anxiety levels and symptom impairment were high and appeared to have increased since the beginning of the pandemic. IU and behavioral manifestations of anxiety were associated with higher anxiety symptoms, impairment and distress related to COVID-19 health standards. The indirect effects of IU on the tendency to worry and COVID-19-related anxiety through behavioral manifestations of anxiety were confirmed. This study provides knowledge on the relationship between COVID-19 and anxiety in older adults and identifies predictors relevant to this population.

The psychological distress and suicide-related ideation in hospital workers during the COVID-19 pandemic: Second results from repeated cross-sectional surveys

The COVID-19 pandemic has been affecting the mental health of hospital workers. During the prolonged pandemic, hospital workers may experience much more severe psychological distress, leading to an increased risk of suicide. This study aimed to investigate changes in psychological effects on hospital workers over 12 months from the beginning of the pandemic and clarify factors associated with psychological distress and suicide-related ideation 1-year after the pandemic's beginning. These repeated, cross-sectional surveys collected demographic, mental health, and stress-related data from workers in 2 hospitals in Yokohama, Japan. The first survey, conducted in March-April 2020, contained the 12-item General Health Questionnaire (GHQ-12) assessing general distress and the Impact of Event Scale-Revised (IES-R) assessing event-related distress. In the second survey in March 2021, hospital workers at the same two hospitals were reassessed using the same questionnaire, and Item 9 of the Patient Health Questionnaire (PHQ-9) was added to assess their suicide-related ideation. The findings of the first and second surveys revealed that the average score of GHQ-12 (3.08 and 3.73, respectively), the IES-R total score (6.8 and 12.12, respectively), and the prevalence rates of severe general distress (35.0% and 44.0%, respectively) and severe event-related distress (7.0% and 17.1%, respectively) deteriorated. The second survey showed that 8.6% of the hospital workers were experiencing suicide-related ideation. Both the general and event-related distress were associated with suicide-related ideation. In these surveys, mental health outcomes among the hospital workers deteriorated over one year from the pandemic's beginning, and their severe psychological distress was the risk factor for the suicide-related ideation. Further studies are needed to compare the psychological effects on hospital workers during and after the prolonged pandemic and to explore appropriate measures to support hospital workers' mental health.

The COLIBAS Study—COVID-19 Lockdown Effects on Mood, Academic Functioning, Alcohol Consumption, and Perceived Immune Fitness: Data from Buenos Aires University Students

A recent study was conducted in the Netherlands to evaluate the impact of the 2019 coronavirus (COVID-19) pandemic and its associated lockdown periods on academic functioning, mood, and health correlates such as alcohol consumption. The study revealed that lockdowns were associated with a significantly poorer mood and a reduced perceived immune fitness. Overall, a reduction was seen in alcohol consumption during the lockdown periods. Academic functioning in terms of performance was unaffected; however, a significant reduction in interactions with other students and teachers was reported. There was, however, great variability between students as follows: both an increase and a reduction in alcohol consumption were reported, as well as improvements and poorer academic functioning. The aim of the current online study was to replicate these findings in Argentina. To this extent, a modified version of the survey was conducted among students at the University of Buenos Aires, which was adapted to the local lockdown measures. The survey assessed possible changes in self-reported academic functioning, mood, and health correlates, such as alcohol consumption, perceived immune functioning, and sleep quality compared to before the COVID-19 pandemic. Retrospective assessments were made for four periods, including (1) the period before COVID-19, (2) the first lockdown period (March–December 2020), (3) summer 2021 (January-March 2021, no lockdown), and (4) the second lockdown (from April 2021 to July 2021). This article describes the content of the survey and the corresponding dataset. The survey was completed by 508 participants.

The effect of medical staff's professional identity on psychological stress during public health emergencies: The role of intolerance of uncertainty and adversity appraisal

This study aims to explore the relationship between medical staff's professional identity and the psychological stress they feel during a public health emergency. It also examines the possible mediating effects of staff's intolerance of uncertainty (IU) and moderating effects of staff's adversity appraisal on this relationship. This study's 447 participants were surveyed via questionnaire. The results indicate that (1) medical staff's sense of their professional identity can negatively predict the psychological stress they feel during public health emergencies; (2) staff's IU mediates the relationship between professional identity and psychological stress; (3) the direct effects of professional identity and psychological stress were moderated by staff's adoption of positive appraisal strategies (negative appraisal strategies), and the direct effect was significant in medical staff who adopted a less positive appraisal strategy (more negative appraisal strategy). Therefore, professional identity was proven to affect staff's psychological stress through their IU, and staff's adversity appraisal plays a moderating role in the direct path of this effect.

Times Are Harsh, Be Kind to Yourself! Anxiety, Life Satisfaction, and the Mediating Role of Self-Compassion

The present research aimed to explore the indirect effect of self-compassion on the relationship between two dimensions of intolerance of uncertainty (i.e., prospective and inhibitory anxiety) and life satisfaction. One hundred sixty-four Romanian adult participants formed our sample from the country's eastern side. Their ages ranged between 18 and 61 (M = 23.45, SD = 7.70, 72% females). The study was conducted in 2021, when the Delta wave of COVID-19 was at its peak. Our findings suggested significant negative associations between prospective anxiety, self-compassion, and life satisfaction. A similar negative significant association was suggested between inhibitory anxiety and self-compassion. Age did not significantly correlate with any of our primary variables. Mediation analyses indicated a total mediating effect of self-compassion on the relationship between participants' prospective and inhibitory anxiety and their life satisfaction. We discuss the implications of our findings, considering their relevance for therapeutical interventions aimed to promote psychological wellbeing when facing adversity.

A Coupled Mathematical Model of the Dissemination Route of Short-Term Fund-Raising Fraud

To effectively protect citizens’ property from the infringement of fund-raising fraud, it is necessary to investigate the dissemination, identification, and causation of fund-raising fraud. In this study, the Susceptible Infected Recovered (SIR) model, Back-Propagation (BP) neural network, Fault tree, and Bayesian network were used to analyze the dissemination, identification, and causation of fund-raising fraud. Firstly, relevant data about fund-raising fraud were collected from residents in the same area via a questionnaire survey. Secondly, the SIR model was used to simulate the dissemination of victims, susceptibles, alerts, and fraud amount; the BP neural network was used to identify the data of financial fraud and change the accuracy of the number analysis of neurons and hidden layers; the fault-tree model and the Bayesian network model were employed to analyze the causation and importance of basic events. Finally, the security measures of fund-raising fraud were simulated by changing the dissemination parameters. The results show that (1) for the spread of the scam, the scale of the victims expands sharply with the increase of the fraud cycle, and the victims of the final fraud cycle account for 12.5% of people in the region; (2) for the source of infection of the scam, the initial recognition rate of fraud by the BP neural network varies from 90.9% to 93.9%; (3) for the victims of the scam, reducing fraud publicity, improving risk awareness, and strengthening fraud supervision can effectively reduce the probability of fraud; and (4) reducing the fraud rate can reduce the number of victims and delay the outbreak time. Improving the alert rate can reduce victims on a large scale. Strengthening supervision can restrict the scale of victims and prolong the duration of fraud.

COVID-19 in Lifespan: Psychological Impact between Young and Older Adults in Argentina

The coronavirus pandemic has had a serious and worldwide impact. The increase in psychopathological symptomatology has affected people regardless of their age but has been observed mainly in the elderly population due to the characteristics of the virus. This study aimed to analyze and compare the psychological impact, as measured by the presence of depressive and anxiety symptoms, in a group of young and older adults at three-time points during the pandemic. Virtual surveys were used to measure participants’ symptomatology and collect socio-demographic information. The results showed a significant increase in anxiety and depression in the general population. However, when comparing the two groups, statistical differences were observed. Younger adults showed higher mean anxiety and depression than older adults, which was sustained across the three times for both groups. Nevertheless, the increase in depressive symptomatology slows in young people between the second and third waves, while it continues to increase in older adults. Those results are a contribution to the study of individual differences in the psychological impact of the COVID-19 pandemic.
