Increasing aggression during the COVID-19 lockdowns

Relationship Between Personality Traits and Emotional Impacts of the COVID-19 Pandemic on Canadian Emerging Adults

We assessed whether traits from the four-factor vulnerability model for substance misuse are associated with the content of emotional descriptions given by Canadian university students of the impact of the COVID-19 pandemic on their lives. Personality traits were measured in 1185 first- and second-year undergraduates (mean age = 19.11 years; 79% female). Written responses to "Tell us about how the COVID-19 pandemic is impacting your life" were coded using Linguistic Inquiry and Word Count software. Negative binomial analyses were run to examine links between traits and emotion word types used in responses. Anxiety sensitivity was associated with increased use of anxiety words; hopelessness was associated with increased use of negative emotion and sadness words, and decreased use of positive emotion words; and impulsivity was associated with increased use of anger words. Findings have implications for personality-tailored interventions for students vulnerable to distress resulting from highly stressful situations such as pandemics.

Short-term social isolation acts on hypothalamic neurons to promote social behavior in a sex- and context-dependent manner

Social animals, including both humans and mice, are highly motivated to engage in social interactions. Short-term social isolation promotes social behavior, but the neural circuits through which it does so remain incompletely understood. Here, we sought to identify neurons that promote social behavior in single-housed female mice, which exhibit increased rates of social investigation, social ultrasonic vocalizations (USVs), and mounting during same-sex interactions that follow a period of short-term (3 days) isolation. We first used immunostaining for the immediate early gene Fos to identify a population of neurons in the preoptic hypothalamus (POA) that increase their activity in single-housed females following same-sex interactions (POAsocial neurons) but not in single-housed females that did not engage in social interactions. TRAP2-mediated chemogenetic silencing of POAsocial neurons in single-housed females significantly attenuates the effects of short-term isolation on social investigation, USV production, and mounting. In contrast, caspase-mediated ablation of POAsocial neurons in single-housed females robustly attenuates mounting but does not decrease social investigation or USV production. Optogenetic activation of POAsocial neurons in group-housed females promotes social investigation and USV production but does not recapitulate the effects of short-term isolation on mounting. To understand whether a similar population of POAsocial neurons promotes social behavior in single-housed males, we performed Fos immunostaining in single-housed males following either same-sex or opposite-sex social interactions. These experiments revealed a population of POA neurons that increase Fos expression in single-housed males following opposite-sex, but not same-sex, interactions. Chemogenetic silencing of POAsocial neurons in single-housed males during interactions with females reduces mounting but does not affect social investigation or USV production. These experiments identify a population of hypothalamic neurons that promote social behavior following short-term isolation in a sex- and social context-dependent manner.

School Safety Concerns and Solutions: A Qualitative Analysis of U.S. School Psychologists' Perspectives

In the present study, we analyzed qualitative survey data from 538 school psychologists across schools in the United States regarding their perceptions of school safety issues and potential strategies to address school safety. There are only a few studies exploring the experiences and perspectives of school psychologists that have been based on large-scale qualitative data. Using inductive coding, three themes for safety concerns emerged: (a) aggressive behaviors from students, (b) mental and behavioral needs, and (c) limited staffing. Three themes also emerged for potential solutions: (a) professional development/training, (b) school-family-community relationships, and (c) threat assessments. These findings from school psychologists have implications for addressing structural issues to prevent school violence in research and practice. Policy recommendations to inform resource allocation and improve school safety are discussed.

The role of social isolation stress in escalated aggression in rodent models

Anti-social behavior and violence are major public health concerns. Globally, violence contributes to more than 1.6 million deaths each year. Previous studies have reported that social rejection or neglect exacerbates aggression. In rodent models, social isolation stress is used to demonstrate the adverse effects of social deprivation on physiological, endocrinological, immunological, and behavioral parameters, including aggressive behavior. This review summarizes recent rodent studies on the effect of social isolation stress during different developmental periods on aggressive behavior and the underlying neural mechanisms. Social isolation during adulthood affects the levels of neurosteroids and neuropeptides and increases aggressive behavior. These changes are ethologically relevant for the adaptation to changes in local environmental conditions in the natural habitats. Chronic deprivation of social interaction after weaning, especially during the juvenile to adolescent periods, leads to the disruption of the development of appropriate social behavior and the maladaptive escalation of aggressive behavior. The understanding of neurobiological mechanisms underlying social isolation-induced escalated aggression will aid in the development of therapeutic interventions for escalated aggression.

Effects of self-compassion on aggression and its psychological mechanism through perceived stress

Given the increasing global concerns about aggressive behaviors and the pressing need for effective psychological interventions, this study delves into the potential of a concept deeply rooted in positive and Buddhist psychology but largely researched in Western contexts, as a mitigating factor against aggression in Chinese adults. Through three core studies involving 652 participants (age: 30.52±8.16), our research illuminated the intricate relationship between self-compassion, perceived stress, and aggression. Study 1 identified a negative correlation among these variables, setting the empirical foundation. In Study 2, participants exposed to a self-compassion exercise reported enhanced self-compassion and reduced aggression. Study 3 further consolidated these findings, with participants in the self-compassion writing group, showing notable increases in self-compassion and decreases in aggression compared to a control group. Critically, perceived stress emerged as a significant mediator between self-compassion and aggression, elucidating its central role in this dynamic. Together, our findings underscore the promise of self-compassion as a strategy to curb aggression tendencies, especially in light of its influential relationship with perceived stress, suggesting vital implications for future mental health interventions.

Literature Review of Deep-Learning-Based Detection of Violence in Video

Physical aggression is a serious and widespread problem in society, affecting people worldwide. It impacts nearly every aspect of life. While some studies explore the root causes of violent behavior, others focus on urban planning in high-crime areas. Real-time violence detection, powered by artificial intelligence, offers a direct and efficient solution, reducing the need for extensive human supervision and saving lives. This paper is a continuation of a systematic mapping study and its objective is to provide a comprehensive and up-to-date review of AI-based video violence detection, specifically in physical assaults. Regarding violence detection, the following have been grouped and categorized from the review of the selected papers: 21 challenges that remain to be solved, 28 datasets that have been created in recent years, 21 keyframe extraction methods, 16 types of algorithm inputs, as well as a wide variety of algorithm combinations and their corresponding accuracy results. Given the lack of recent reviews dealing with the detection of violence in video, this study is considered necessary and relevant.

Examining enduring effects of COVID-19 on college students' internalizing and externalizing problems: A four-year longitudinal analysis

BACKGROUND

College students' mental health has been a vital concern for researchers, policymakers, administrators, and educators since before the pandemic, and it is crucial to identify the extent to which the pandemic affected college students' mental health.

METHODS

The current study utilized data repeatedly collected over more than four years (2017-2022) from N = 355 students enrolled at a large public research university in the Midwestern US. The data collection period coincided with the COVID-19 pandemic's onset, facilitating systematic examination of whether and how college students' trajectories (i.e., level and slopes) of depressive symptoms, social anxiety, general disinhibition, callous aggression, and problematic alcohol use changed as the pandemic progressed. Across seven waves, surveys assessed multiple outcome and predictor domains. Multilevel growth curve modeling was used to analyze all outcomes.

RESULTS

Depression symptoms peaked mid-pandemic, whereas social anxiety first declined then continued rising. General disinhibition and callous aggression showed non-significant changes in trajectories. Problematic alcohol use decreased continuously with no significant pandemic-associated effects in the best-fitting model.

LIMITATIONS

An important limitation is reliance on a sample from a single campus utilizing self-reported, non-clinical assessments. Another important limitation is the lack of location information from participants during the acute COVID-19 phase.

CONCLUSIONS

Reported longitudinal analyses expand upon findings from previous limited repeated-measures and cross-sectional studies. In terms of clinical significance, some of the most harmful COVID-19 effects to mental health may be long-lasting and cumulative, making them difficult to detect in shorter-term or cross-sectional studies. Altogether, findings demonstrate complex changes in students' mental health that may have ongoing effects on well-being during key developmental stages.

A monetary model of global peace and health

BACKGROUND

This study aims to expand on the concept of peace and health by drawing from Keynes' theory of the economic consequences of peace, in light of the global pandemic experienced in 2020 due to COVID_19.

METHODS

In this paper, I will elaborate on the concept of 'security', as an indicator of peace in the time of biological shocks, in order to expand the definition of Keynesian precautionary motivation. This puts forth a new monetary policy model developed to make contributions to achieving global peace. In so doing, I will calculate the optimal growth rate of discount rate through utilizing the Global Peace Index (GPI), adjusted by the Case Fatality Risk (CFR) of COVID-19 in a dynamic shopping time monetary model. This analysis is comprised of the top 15 GDP countries as well as the 10 most and least peaceful countries in 2020.

RESULTS

The results indicate that households in more peaceful and healthy countries tend to hold less money compared to those in less peaceful and healthy countries. Besides, the discount rate needs to be reduced due to the outbreak of COVID-19 and the decrease in the level of peace in the economy.

CONCLUSION

Insofar as the imposition of fines through international legal circles on countries with an insignificant health and peace policy will increase the cost of liquidity, other alternative methods of financing will be affor dable for the countries.

Emotional, coping factors and personality traits that influenced alcohol consumption in Romanian students during the COVID-19 pandemic. A cross-sectional study

BACKGROUND

During the COVID-19 pandemic, after 3 months from the installation of the state of emergency on the territory of Romania, data were collected from 677 students and master's students, to explore the problematic alcohol consumption (AC).

METHODS

The evaluation was done with: Alcohol Use Disorders Identification Test, Depression, Anxiety and Stress Scales, Strategic Coping Approach Scale and The Freiburg Personality Inventory. The statistical methods used were linear regression with bootstrap procedure, Spearman's rank correlation, and the Mann-Whitney U test.

RESULTS

More than half were affected by depression or anxiety of moderate to extremely severe intensity. The prevalence of problematic alcohol consumption was low: (Hazardous and Extremely Hazardous (2.3) and Medium Risk (10.2). Early onset increases the subsequent risk of problematic AC, compared to women, men recorded a higher AC (p <.01). Anxiety, antisocial action, personality traits Aggressiveness and Somatic complaints had the effect of increasing the alcohol consumption score (p <.01). Significant but weak positive correlations between AC on one hand, and depression, anxiety, stress and antisocial action on the other hand were found (p <.01).

CONCLUSIONS

Probably the prevalence of AC was low as a result of the fact that most respondents were studying in the field of health promotion and as a result of the closure of entertainment venues. This study advocates for the education of youngsters to clearly express their opinions without violating the boundaries of others' feelings (assertive action) and to act prudently in dangerous or uncertain situations (cautious action) since these coping mechanisms were not associated with problematic alcohol consumption. The promotion of positive, achievement-oriented, life attitudes is equally important, as these characteristics of the Life Satisfaction personality dimensions were also found as non-determinants of alcohol-induced problems. The association of problematic AC with antisocial actions as a coping mechanism and high scores on Aggressiveness calls for interventions to educate the younger generation how to acquire and adopt healthy mechanisms to control tensions without resorting to alcohol consumption, more so as the two variables reinforce each other. Drinking as a means of gaining courage must be carefully reconsidered since anxiety generally hits back, often in increased levels.

Racial discrimination moderates associations between sociopolitical discussions and internalizing problems among racially minoritized college students

OBJECTIVE

The present study investigated whether associations between sociopolitical discussions and mental health differed by racial discrimination among racially minoritized college students. We also tested whether associations differed between election years-when sociopolitical discussions may be more frequent-and nonelection years.

METHOD

In November 2020, racially minoritized college students (N = 225; Mage = 19.84, SD = 1.41; 72.89% female; 52.00% Asian, 22.67% Latino, 16.00% multiracial, 9.33% races including Black and Middle Eastern) reported how often they had experienced racial discrimination, their frequency of sociopolitical discussions with friends and family, and their mental health.

RESULTS

Results indicated that participants who had more frequent sociopolitical discussions with friends-but not family-only reported more internalizing problems if they had never or rarely experienced racial discrimination in the past year. To determine whether results were unique to discussions during election years, a second sample (N = 262; Mage = 20.18, SD = 2.30; 82.53% female; 48.86% Asian, 18.56% Latino, 15.42% multiracial, 17.78% races including Black and Middle Eastern) was recruited 1 year later, and racial discrimination did not moderate associations between sociopolitical discussions and internalizing problems.

CONCLUSIONS

Sociopolitical discussions with friends during presidential elections may be related to greater internalizing problems for racially minoritized college students who experience racial discrimination less frequently, potentially because they may feel less prepared or less motivated to have these conversations compared to racially minoritized college students who experience racial discrimination more frequently. Future studies should investigate means of promoting sociopolitical discussions on campus while attenuating the association between sociopolitical discussions and internalizing problems.

Neurobiological metric of cortical delay discounting differentiates risk for self- and other-directed violence among trauma-exposed individuals

Self- and other-directed violence (SDV/ODV) contribute to elevated rates of mortality. Early trauma exposure shows robust positive associations with these forms of violence but alone does not distinguish those at heightened risk for later engagement in SDV/ODV. Novel assessment metrics could aid early identification efforts for individuals with vulnerabilities to violence perpetration. This study examined a novel neurobiological measure of impulsive choice for reward as a potential moderator of associations between childhood trauma exposure and lifetime SDV/ODV. A high-risk community sample of 177 adults (89 men; 50.3%) were assessed for childhood trauma exposure, engagement in SDV (e.g., suicide attempts), and ODV (e.g., assault). A cortical delay discounting (C-DD) measure was created using a multivariate additive model of gray matter thickness across both hemispheres, previously found to be positively associated with susceptibility to impulsivity and externalizing disorders. Childhood trauma exposure was positively associated with ODV and SDV; however, these relationships differed as a function of C-DD. Engagement in ODV increased as scores on C-DD increased, and SDV increased as scores on C-DD decreased. Furthermore, moderation revealed biological sex differences, as the association between childhood trauma and SDV depended on C-DD for women but not for men. Findings from the present work demonstrate that risk conferred by childhood trauma exposure to violence varied as a function of a C-DD. Together, these findings point to the utility of neurobiological markers of impulsive decision-making for differentiating risk for violence among individuals with a history of trauma exposure.

Suicidal and aggressive behavior among populations within institutional quarantine and isolation centers of COVID-19 in eastern Ethiopia: A cross-sectional study

INTRODUCTION

The coronavirus disease is still not under the control globally and has caused various mental health problems such as depression, anxiety, suicide, and aggressive behavior in different populations. The pandemic-related issues which are applied to control the pandemic such as protection measures against COVID-19, social distancing, isolation, and quarantine can also trigger mental health problems.

OBJECTIVE

This study aimed to assess suicidal behavior and aggression, and its correlates during COVID-19 among populations within institutional quarantine and isolation centers in Ethiopia.

METHOD

A cross-sectional study was conducted among a sample of 392 participants. The convenience sampling method was used to select the study participants. Suicide Behavioral Questionnaire-Revised (SBQ-R) and the Modified Overt Aggression Scale (MOAS)were applied to determine the suicide and aggressive behavior of study participants respectively. Epi-data 3.1 and SPSS 20.0were used to enter and analyze the data respectively. Logistic and linear regressions were fitted to explore correlates associated with suicidal behavior and aggression respectively.

RESULTS

The prevalence of suicidal behavior was 8.7% (95% CI: 6.1, 11.5) whereas the mean total score of behavioral aggression was 2.45±5.90 (95% CI: 1.84, 3.08). Being female (AOR = 2.63, 95% CI: 1.09, 6.32), having common mental disorders (AOR = 6.08, 95% CI: 2.32, 15.93), manifesting the symptoms of COVID-19 (AOR = 2.17, 95% CI: 1.48, 2.86), and poor social support (AOR = 7.30, 95% CI: 1.44, 37.10) were significantly associated with suicidal behavior, whereas male gender (β coefficient = 3.0, 95% CI: 1.35, 4.70), low level of knowledge about COVID-19 (β coefficient = 1.87, 95% CI: 1.09, 3.41), and substance use (β coefficient = 1.7, 95% CI: 1.23, 6.47) were positively associated with mean overt aggression score.

CONCLUSION

The present study revealed that suicidal and aggressive behaviors were prevalent with significant correlates. Therefore, it is important and required to provide focused mental health and psycho-social services for the selected and high-risk populations such as those in quarantine and isolation centers for being suspected.

Depression, Anxiety, and Stress During COVID-19 Pandemic Among Females Who Live in Kuwait

Health regulations to constrain the progress of the pandemic such as lockdowns, curfews, and quarantines made radical alterations in every aspect of individuals' lives, causing significant impact on their mental health and well-being. The current study aimed to examine whether there are significant differences in participants' sociodemographic variables in reported cases of depression, anxiety, and stress among women who lived in Kuwait during the curfew and lockdown caused by COVID-19 pandemic. This study used a cross-sectional method. A nonrandom sample of 596 participants was recruited. The current study found that women at higher risk of reporting more incidents of depression, anxiety, and stress during the lockdown and curfew were from the older age group above 50 years old, hold higher educational certificates, and own private businesses. High rates of reported depression and anxiety were detected significantly among Kuwaiti women. The findings of this study reveal the significant impact of an uncomfortable and distressful environment during the COVID-19 pandemic, which may negatively affected individuals' mental health and generated diverse forms of psychosocial illness.

Has Anything Changed in the Frequency of Emergency Department Visits and the Profile of the Adolescent Seeking Emergency Mental Care during the COVID-19 Pandemic?

We described changes caused by the COVID-19 pandemic in the frequency of Emergency Department (ED) visits for mental health disorders (MHDs) in adolescents on a wider temporal range—that is, not just “the waves” of the pandemic—and characterized the profile of the adolescent seeking emergency psychiatric care. We conducted a retrospective longitudinal study by analyzing ED visits for MHDs from 10 March 2019 to 10 March 2021. A total of 1407 ED visits for MHDs were registered: 702 in the pre-COVID-19 and 707 in the COVID-19 period. The cumulative incidence of ED visits for MHDs was 1.22% in the pre-COVID-19 period and 1.77% in the COVID-19 period, with a statistically significant difference (p < 0.001). The principal characteristics of the adolescent with MHDs during the pandemic period: the odds of comorbidities decreased by 26% (p = 0.02), and the odds of transfer from other hospitals decreased by 71% (p < 0.001), while the odds of the ED presentation as first psychiatric episode were twice greater (p < 0.001). The risk of hospitalization increased by 54% (p = 0.001). Regarding psychopathology, the likelihood of attempted suicide increased by 74% during the pandemic (p = 0.02). The rate of mood and eating disorders grew significantly during the COVID-19 pandemic period (p = 0.005 and p = 0.031, respectively). Monitoring ED visits for MHDs and understanding changes in the profile of adolescents presenting to ED helps to reinforce the role of ED in identifying special clinical needs for these vulnerable patients in case of a future public health crisis.

Second Victim Phenomenon in an Austrian Hospital before the Implementation of the Systematic Collegial Help Program KoHi: A Descriptive Study

(1) Background: The Second Victim Phenomenon (SVP) is widespread throughout health care institutions worldwide. Second Victims not only suffer emotional stress themselves; the SVP can also have a great financial and reputational impact on health care institutions. Therefore, we conducted a study (Kollegiale Hilfe I/KoHi I) in the Hietzing Clinic (KHI), located in Vienna, Austria, to find out how widespread the SVP was there. (2) Methods: The SeViD (Second Victims in Deutschland) questionnaire was used and given to 2800 employees of KHI, of which 966 filled it in anonymously. (3) Results: The SVP is prevalent at KHI (43% of the participants stated they at least once suffered from SVP), although less prevalent and pronounced than expected when compared to other studies conducted in German-speaking countries. There is still a need for action, however, to ensure a psychologically safer workspace and to further prevent health care workers at KHI from becoming psychologically traumatized.

Factors Associated with Insomnia and Aggression among Healthcare Workers during COVID-19 Pandemic

(1) Healthcare workers are exposed to increased risks of insomnia and aggression during the COVID-19 pandemic. The aim of the study was to assess insomnia, sleep disturbances, and aggression and identify the associated risk factors among healthcare workers during the COVID-19 pandemic. (2) A total of 264 healthcare workers participated in the study. The study was conducted with the diagnostic survey method, using the Buss−Perry Aggression Questionnaire, the Athens Insomnia Scale, the Pittsburgh Sleep Quality Index, and a self-administered questionnaire. (3) The vast majority of the respondents (81.06%) suffered from insomnia and had poor sleep quality (78.03%). Education (p = 0.038), marital status (p = 0.043), and working with patients suffering from COVID-19 (p = 0.024) were statistically significant contributors to insomnia. Age was found to significantly correlate with total aggression (r = −0.133 p = 0.031), verbal aggression (r = −0.138 p = 0.025), and anger (r = −0.151 p = 0.014). The analysis demonstrated statistically significant relationships between gender and physical aggression (p = 0.017), anger (p = 0.032), and hostility (p = 0.002). A statistically significant positive correlation between the quality of sleep as per the PSQI and all subscales of the BPAQ was found (p < 0.001). (4) A considerable proportion of HCWs experienced sleep disturbances during the outbreak, stressing the need to establish ways to reduce long-term adverse outcomes associated with chronic insomnia and mental health problems and adjust interventions under pandemic conditions.

Changes in ambulance departures for assault calls during COVID-19 pandemic restrictions

Restrictions related to COVID-19 changed the daily behavior of people, including the expression of violence. Although an increased incidence of violent behavior, especially domestic violence, was expected during the pandemic, retrospective analyses have yielded mixed results. Records of ambulance departures to address injuries caused by assaults in the Pilsen region, Czech Republic, during the restrictive measures during the national state of emergency were compared to data from 3 previous years using general linear models. The number and severity of assaults were analyzed for the whole sample and separately for patients of either sex, for residential or nonresidential locations, and for domestic violence. Controlling for the seasonal effects, the number of assaults decreased by 39% during the pandemic restrictions compared to the 3 previous years. No difference was found between the effects of restrictions on assaults resulting in an injury of a male or female patient. The decrease was specifically pronounced in the sample of assaults in nonresidential locations, while no effect of restrictions was observed in assaults in residential locations and domestic assaults. Pandemic restrictions were associated with a decreased incidence of violent assaults that required ambulance services. Although the incidence decreased especially in those assaulted outside of their homes, we found no support for an increase in domestic violence or violence against women. Pandemic restrictions may have served as a protective rather than a risk factor for assaults severe enough to warrant a call for ambulance services.

Trait anger and negative interpretation bias in neutral face perception

Introduction

Anger is a basic emotion helping people to achieve goals by preparing the body for action and prompting others to change their behavior but is also associated with health issues and risks. Trait anger, the disposition to experience angry feelings, goes along with an attribution of hostile traits to others. Negative distortions in the interpretation of social information have also been observed in anxiety and depression. The present study examined the associations between components of anger and negative interpretation tendencies in the perception of ambiguous and neutral schematic faces controlling for anxiety, depressed mood, and other variables.

Methods

A sample of 150 young adults performed a computer-based perception of facial expressions task and completed the State-Trait Anger Expression Inventory (STAXI-2) along with other self-report measures and tests.

Results

Trait anger and anger expression correlated with the perception of negative affects in neutral but not in ambiguous faces. More specifically, trait anger was linked to the attribution of anger, sadness, and anxiety to neutral faces. Trait anger predicted perceived negative affects in neutral faces when adjusting for anxiety, depression, and state anger.

Discussion

For neutral schematic faces, the present data support an association between trait anger and negatively biased interpretation of facial expression, which is independent of anxiety and depressed mood. The negative interpretation of neutral schematic faces in trait angry individuals seems not only to comprise the attribution of anger but also of negative emotions signaling weakness. Neutral schematic facial expressions might be useful stimuli in the future study of anger-related interpretation biases.

Internet gaming disorder and aggression: A meta-analysis of teenagers and young adults

Background and aims

Internet gaming disorder (IGD) and aggression (AG) are widespread phenomena around the world. Numerous studies have explored the relationship between the two but findings from such studies are inconsistent. The meta-analysis aimed to evaluate the relationship between IGD and AG as well as identify the variables moderating the relationship.

Method

Studies investigating the relationship between IGD and AG were searched using selected terms to identify studies published from 1999 to 2022 on CNKI, Wanfang Data, Chongqing VIP Information Co., Ltd. (VIP), Baidu scholar, ProQuest dissertations, Taylor & Francis, Springer, Web of Science, Google Scholar, Elsevier Science (Science Direct), EBSCO, and PsycINFO. The identified studies were pooled and analyzed.

Results

A total of 30 samples comprising 20,790 subjects were identified. Results showed that there was a moderate relationship between IGD and AG (r = 0.300, 95%CI [0.246, 0.353]). Moderator analysis revealed that the relationship between IGD and AG was moderated by the region, age, and survey year.

Conclusion

This meta-analysis indicated that people with a higher level of IGD might show more aggression, and people with more aggression might have a higher level of IGD. The correlation coefficient between IGD and AG was significantly higher in Asia than in Europe, higher in primary school than in middle school and university, and higher by increasing year. Overall, our findings provide a basis for developing prevention and intervention strategies against IGD and AG.

Sense of Coherence and Self-Rated Aggression of Adolescents during the First Wave of the COVID-19 Pandemic, with a Focus on the Effects of Animal Assisted Activities

The COVID-19 pandemic has caused extreme deviations from everyday life. The aim of this study was to investigate how these deviations affected adolescents' sense of coherence and their level of aggression, and whether this was influenced by their relationship with animals, especially horses. In two random samples of students from vocational schools in Hungary, taken in June 2018 and June 2020 (n1 = 525, n2 = 412), separate groups were drawn from those who had regularly engaged in equine-assisted activities (ES) and those who had not (OS) before the pandemic. Data were collected using an anonymous, paper-based questionnaire, and during the pandemic an online version of the Sense of Coherence (SOC13) and Bryant-Smith (B12) scales. During the pandemic, boys' sense of coherence weakened and their aggressiveness increased. Multiple linear regression analyses showed that, regardless of gender and age group, increased time spent using the internet (p < 0.001), a lack of classmates (p = 0.017), reduced time spent outdoors (p = 0.026) and reduced physical activity (p < 0.038) during the pandemic significantly increased the tendency for aggressive behavior, whereas being with a horse or pet was beneficial (p < 0.001). The changes imposed by the curfew were rated as bad by 90% of the pupils, however, those with a strong sense of coherence felt less negatively about them. Schools should place a great emphasis on strengthening the students' sense of coherence.

The relationship between spirituality and aggression in the workplace during the COVID-19 pandemic: A cross-sectional study among Iranian nurses

BACKGROUND

Aggression towards nurses in the workplace arises from various reasons, reportedly increasing during the COVID-19 pandemic. Where aggression can be maintained by spiritual well-being, as it is said that spirituality is a coping skill and psychological well-being maintainer-but there is little known, especially during the pandemic. Thus, this study explored the effect of spirituality on aggression among the nurses working in the COVID-19 wards.

METHODS

This cross-sectional data from 200 nurses involved in the COVID-19 patient treatment were collected using a random sampling method from four hospitals in East Mazandaran province, Iran. Responses were collected based on socio-demographics, Buss-Perry Aggression Questionnaire, and Paloutzian & Ellison Spiritual Well-being Scale. T-test, ANOVA, Pearson correlation coefficient, and multiple linear regression were applied for data analysis.

RESULTS

The mean age of nurses was 31.49±6.88 (range: 21-48) years. Nurses working in the COVID-19 wards have a mean score of spiritual health of 67.21±12.84 (out of 120), whereas 51.77±10.96 (out of 116) was for aggression. The results showed a significant negative weak correlation between aggression and spiritual health (r = -.285, p<0.01). As per regression analysis, spiritual health [β = -.264], age [β = -.374], and working experience [β = 4.156] were the significant factors associated with aggression (p<0.05).

CONCLUSIONS

It is evident that nurses who consider spirituality in their life actions are in a state of reduced negative emotions, such as aggression. Thus, policymakers and managers of the healthcare settings are suggested to promote spirituality among the nurses through spiritual care education, providing the ground for promoting spirituality and a positive attitude towards it.

Aggressive behavior, boredom, and protective factors among college students during closed-off management of the COVID-19 pandemic in China

Background

Chinese colleges have implemented strict closed-off management in response to the outbreak of a new variant of the new coronavirus, Omicron. But such management measures may lead to more aggressive behavior. The study aimed to determine the associations between boredom and aggressive behavior with aggression and to examine the impact of boredom on aggression through the moderating role of cognitive flexibility.

Methods

The Multidimensional State Boredom Scale, the Reactive-Proactive Aggression Questionnaire, and the Cognitive Flexibility Inventory were applied to a sample of 719 college students who were in a closed-off management environment.

Results

For individuals with high cognitive flexibility, the relationship between state boredom and proactive aggression was not significant. The relationship between state boredom and proactive aggression was significantly positively correlated for individuals with low cognitive flexibility, especially low substitutability. Cognitive flexibility has no significant moderating effect on the relationship between state boredom and reactive aggression.

Conclusion

The findings highlighted the importance of boredom as a potential risk factor for aggression, while cognitive flexibility appears as a potential protective factor.

Experiencing Stress During COVID-19: A Computational Analysis of Stressors and Emotional Responses to Stress

This study aims to unveil how COVID-19 affected the experience of stress by focusing on the stressors. Using computational analysis based on a newly developed stressor identification model, we compared the experience of stress expressed by Korean Twitter users before and during the pandemic in terms of (1) the stressors as the source of stress and (2) emotion as the manifestation of stress. Both tweet-level (N = 202,556) and user-level (N = 24,803) analyses revealed that social factors are prevalent sources of stress both before and during the pandemic. Moreover, social stressors increased the most during the pandemic. While stress from social stressors was manifested mainly as sadness before the pandemic, anger became the predominant emotional manifestation during the pandemic. Public health policies and educators should consider social stressors as the predominant source of stress during the pandemic and seek ways to prepare the public better for such threats.

Aggressive measures, rising inequalities, and mass formation during the COVID-19 crisis: An overview and proposed way forward

A series of aggressive restrictive measures were adopted around the world in 2020-2022 to attempt to prevent SARS-CoV-2 from spreading. However, it has become increasingly clear the most aggressive (lockdown) response strategies may involve negative side-effects such as a steep increase in poverty, hunger, and inequalities. Several economic, educational, and health repercussions have fallen disproportionately on children, students, young workers, and especially on groups with pre-existing inequalities such as low-income families, ethnic minorities, and women. This has led to a vicious cycle of rising inequalities and health issues. For example, educational and financial security decreased along with rising unemployment and loss of life purpose. Domestic violence surged due to dysfunctional families being forced to spend more time with each other. In the current narrative and scoping review, we describe macro-dynamics that are taking place because of aggressive public health policies and psychological tactics to influence public behavior, such as mass formation and crowd behavior. Coupled with the effect of inequalities, we describe how these factors can interact toward aggravating ripple effects. In light of evidence regarding the health, economic and social costs, that likely far outweigh potential benefits, the authors suggest that, first, where applicable, aggressive lockdown policies should be reversed and their re-adoption in the future should be avoided. If measures are needed, these should be non-disruptive. Second, it is important to assess dispassionately the damage done by aggressive measures and offer ways to alleviate the burden and long-term effects. Third, the structures in place that have led to counterproductive policies should be assessed and ways should be sought to optimize decision-making, such as counteracting groupthink and increasing the level of reflexivity. Finally, a package of scalable positive psychology interventions is suggested to counteract the damage done and improve humanity's prospects.

Increased Online Aggression During COVID-19 Lockdowns: Two-Stage Study of Deep Text Mining and Difference-in-Differences Analysis

BACKGROUND

The COVID-19 pandemic caused a critical public health crisis worldwide, and policymakers are using lockdowns to control the virus. However, there has been a noticeable increase in aggressive social behaviors that threaten social stability. Lockdown measures might negatively affect mental health and lead to an increase in aggressive emotions. Discovering the relationship between lockdown and increased aggression is crucial for formulating appropriate policies that address these adverse societal effects. We applied natural language processing (NLP) technology to internet data, so as to investigate the social and emotional impacts of lockdowns.

OBJECTIVE

This research aimed to understand the relationship between lockdown and increased aggression using NLP technology to analyze the following 3 kinds of aggressive emotions: anger, offensive language, and hate speech, in spatiotemporal ranges of tweets in the United States.

METHODS

We conducted a longitudinal internet study of 11,455 Twitter users by analyzing aggressive emotions in 1,281,362 tweets they posted from 2019 to 2020. We selected 3 common aggressive emotions (anger, offensive language, and hate speech) on the internet as the subject of analysis. To detect the emotions in the tweets, we trained a Bidirectional Encoder Representations from Transformers (BERT) model to analyze the percentage of aggressive tweets in every state and every week. Then, we used the difference-in-differences estimation to measure the impact of lockdown status on increasing aggressive tweets. Since most other independent factors that might affect the results, such as seasonal and regional factors, have been ruled out by time and state fixed effects, a significant result in this difference-in-differences analysis can not only indicate a concrete positive correlation but also point to a causal relationship.

RESULTS

In the first 6 months of lockdown in 2020, aggression levels in all users increased compared to the same period in 2019. Notably, users under lockdown demonstrated greater levels of aggression than those not under lockdown. Our difference-in-differences estimation discovered a statistically significant positive correlation between lockdown and increased aggression (anger: P=.002, offensive language: P<.001, hate speech: P=.005). It can be inferred from such results that there exist causal relations.

CONCLUSIONS

Understanding the relationship between lockdown and aggression can help policymakers address the personal and societal impacts of lockdown. Applying NLP technology and using big data on social media can provide crucial and timely information for this effort.

The relationship between internet addiction and aggressive behavior among adolescents during the COVID-19 pandemic: Anxiety as a mediator

The COVID-19 pandemic has brought unprecedented challenges for adolescents, who tended to experience more emotional instability, impulsivity, and aggressive behavior driven by the fear of infection and the uncertainty of network information. In the present study, we investigated the relationship between Internet addiction and aggressive behavior, and the mediating effects of depression and anxiety. There were differences in Internete addiction and aggressive behavior in gender, thus the moderating role of gender between them were explored. A total of 1148 middle school students were invited to complete the Buss Perry Aggression Questionnaire, the Internet Addition Scale, the Self-rating Depression Scale (SDS), and the Self-rating Anxiety Scale (SAS) separately. The results suggested that 1) there was a significant positive correlation between Internet addiction and aggressive behavior; 2) anxiety, but not depression, mediated the effect of Internet addiction on aggressive behavior; 3) gender did not moderate the effect of Internet addiction on aggressive behavior. The practical implication of the current findings on boosting adolescents' mental health was discussed and further suggestions were provided.

Coping with the COVID-19 Pandemic: Perceived Changes in Psychological Vulnerability, Resilience and Social Cohesion before, during and after Lockdown

The COVID-19 pandemic and associated lockdowns have posed unique and severe challenges to our global society. To gain an integrative understanding of pervasive social and mental health impacts in 3522 Berlin residents aged 18 to 65, we systematically investigated the structural and temporal relationship between a variety of psychological indicators of vulnerability, resilience and social cohesion before, during and after the first lockdown in Germany using a retrospective longitudinal study design. Factor analyses revealed that (a) vulnerability and resilience indicators converged on one general bipolar factor, (b) residual variance of resilience indicators formed a distinct factor of adaptive coping capacities and (c) social cohesion could be reliably measured with a hierarchical model including four first-order dimensions of trust, a sense of belonging, social interactions and social engagement, and one second-order social cohesion factor. In the second step, latent change score models revealed that overall psychological vulnerability increased during the first lockdown and decreased again during re-opening, although not to baseline levels. Levels of social cohesion, in contrast, first decreased and then increased again during re-opening. Furthermore, participants who increased in vulnerability simultaneously decreased in social cohesion and adaptive coping during lockdown. While higher pre-lockdown levels of social cohesion predicted a stronger lockdown effect on mental health, individuals with higher social cohesion during the lockdown and positive change in coping abilities and social cohesion during re-opening showed better mental health recovery, highlighting the important role of social capacities in both amplifying but also overcoming the multiple challenges of this collective crisis.

Knowledge, Attitude, and Practice (KAP) toward COVID-19 Pandemic among the Public in Taiwan: A Cross-Sectional Study

Purpose: Knowledge, attitude, and practice (KAP) models are often used by researchers in the field of public health to explore people’s healthy behaviors. Therefore, this study mainly explored the relationships among participants’ sociodemographic status, COVID-19 knowledge, affective attitudes, and preventive behaviors. Method: This study adopted an online survey, involving a total of 136 males and 204 females, and used a cross-sectional study to investigate the relationships between variables including gender, age, COVID-19 knowledge, positive affective attitudes (emotional wellbeing, psychological wellbeing, and social wellbeing), negative affective attitudes (negative self-perception and negative perceptions of life), and preventive behaviors (hygiene habits, reducing public activities, and helping others to prevent the epidemic). Results: The majority of participants in the study were knowledgeable about COVID-19. The mean COVID-19 knowledge score was 12.86 (SD = 1.34, range: 7−15 with a full score of 15), indicating a high level of knowledge. However, the key to decide whether participants adopt COVID-19 preventive behaviors was mainly their affective attitudes, especially positive affective attitudes (β = 0.18−0.25, p< 0.01), rather than COVID-19 disease knowledge (β = −0.01−0.08, p > 0.05). In addition, the sociodemographic status of the participants revealed obvious differences in the preventive behaviors; females had better preventive behaviors than males such as cooperating with the epidemic prevention hygiene habits (t = −5.08, p< 0.01), reducing public activities (t = −3.00, p< 0.01), and helping others to prevent the epidemic (t = −1.97, p< 0.05), while the older participants were more inclined to adopt preventive behaviors including epidemic prevention hygiene habits (β = 0.18, p = 0.001, R2 = 0.03), reducing public activities (β = 0.35, p< 0.001, R2 = 0.13), and helping others to prevent the epidemic (β = 0.27, p< 0.001, R2 = 0.07). Conclusions: Having adequate COVID-19 knowledge was not linked to higher involvement in precautionary behaviors. Attitudes toward COVID-19 may play a more critical function in prompting individuals to undertake preventive behaviors, and different positive affective attitudes had different predictive relationships with preventive behaviors.

Targeting PSD95/nNOS by ZL006 alleviates social isolation-induced heightened attack behavior in mice

RATIONALE

Deregulated attack behaviors have devastating social consequences; however, satisfactory clinical management for the behavior is still an unmet need so far. Social isolation (SI) has been common during the COVID-19 pandemic and may have detrimental effects on mental health, including eliciting heightened attack behavior.

OBJECTIVES

This study aims to explore whether injection of ZL006 can alleviate SI-induced escalation of attack behavior in mice.

METHODS

Pharmacological tools, biochemical methods, and behavioral tests were used to explore the potential therapeutic effects of ZL006 targeting postsynaptic density 95 (PSD95)/neuronal nitric oxide synthase (nNOS) pathway on escalation of attack behavior induced by SI in mice.

RESULTS

ZL006 mitigated SI-induced escalated attack behaviors and elevated nitric oxide (NO) level in the cortex of the SI mice. The beneficial effects of ZL006 lasted for at least 72 h after a single injection of ZL006. Potentiation of NO levels by L-arginine blocked the effects of ZL006. Moreover, a sub-effective dose of 7-NI in combination with a sub-effective dose of ZL006 decreased both SI-induced escalated attack behaviors and NO levels in mice subjected to SI.

CONCLUSIONS

Our study highlights the importance of the PSD95/nNOS pathway in mediating SI-induced escalation of attack behavior. ZL006 may be a promising therapeutic strategy for treating aggressive behaviors.

Relationship between the Severity of Anxiety Symptoms, Aggression and Alcohol Consumption during the COVID-19 Pandemic Period

Background and objectives: There have been many reports of mental health in the pandemic period. The research conducted so far has indicated an increase in the severity of anxiety and aggression and an escalation of alcohol consumption during the COVID-19 pandemic. The aim of this study was to determine the relationship between the severity of anxiety, the amount of alcohol consumed and the severity of aggression. Materials and Methods: A total of 538 Polish residents—413 women (76.77%) and 125 men (23.23%)—participated in the study via an online survey. It included socio-demographic parameters and psychological scales: AUDIT—to determine the model of alcohol consumption, GAD-7—to measure the severity of anxiety and the Buss–Perry Aggression Questionnaire. Results: There was a correlation between the severity of anxiety and generalized aggression, and its two components—anger and hostility—in the entire study group. Moreover, relations were found between the intensity of alcohol consumption and generalized aggression and its components—anger and verbal and physical aggression. Those relationships turned out to be gender specific. The increased anxiety intensity affected the pattern of alcohol consumption and the severity of aggression. Conclusions: Psychotherapeutic and psychoeducational interactions and some elements of psychiatric treatment should aim at reducing the severity of anxiety in society, and thus minimizing the health and social consequences—aggressive behaviour and excessive alcohol consumption.

Targeting GluN2B/NO Pathway Ameliorates Social Isolation-Induced Exacerbated Attack Behavior in Mice

Exacerbated attack behavior has a profound socioeconomic impact and devastating social consequences; however, there is no satisfactory clinical management available for an escalated attack behavior. Social isolation (SI) is widespread during this pandemic and may exert detrimental effects on mental health, such as causing heightened attack behavior. To explore the therapeutic approaches that alleviate the SI-induced heightened attack behavior, we utilized pharmacological methods targeting the GluN2B/NO signaling pathway during the attack behavior. Ifenprodil and TAT-9C peptide targeting GluN2B showed that the inhibition of GluN2B mitigated the SI-induced escalated attack behavior and the SI-induced aberrant nitric oxide (NO) level in the brain. Additionally, the potentiation of the NO level by L-arginine reversed the effects of the inhibition of GluN2B. Moreover, we showed that high doses of L-NAME and 7-NI and subeffective doses of L-NAME in combination with ifenprodil or TAT-9C or subeffective doses of 7-NI plus ifenprodil or TAT-9C all decreased the SI-induced escalated attack behavior and reduced the NO level, further supporting the idea that GluN2B/NO signaling is a crucial modulator of the escalated attack behavior.
