The role of core self-evaluations and ego-resiliency in predicting resource losses and gains in the face of the COVID-19 crisis: the perspective of conservation of resources theory.

OBJECTIVES: The purpose of the present study was to investigate, through the lens of conservation of resources theory, the predictive role of 2 positive personality traits in the form of core self-evaluations (CSE) and ego-resiliency (ER) in resource losses and gains triggered by the COVID-19 crisis. MATERIAL AND METHODS: The 2 personality traits, constituting positive person-related resources, were examined in relation to resource losses and gains in both general and distinct life domains: hedonistic and vital, spiritual, family, economic and political, and finally power and prestige. RESULTS: The findings from a nationwide sample of 1000 working adults (65% women; age M±SD 38.93±10.9 years) indicated that CSE negatively predicted resource losses, whereas ER served as a positive predictor of resource gains. The predictive role of personality traits was demonstrated both for resource losses and gains in general and in different life domains. CONCLUSIONS: The results of this study highlight in particular the role of CSE as a protective factor of resource losses, and the role of ER as a promotive factor of resource gains, suggesting that both traits might evoke divergent resilience responses when facing prolonged stressful life events.

Effect of COVID-19 on Blood Pressure Profile and Oxygen Pulse during and after the Cardiopulmonary Exercise Test in Healthy Adults.

Several reports have shown the impact of COVID-19 history on exercise capacity. This study compared the blood pressure (BP) response and oxygen pulse (O2 pulse) characteristics in normotensive patients with and without a history of COVID-19 during the cardiopulmonary exercise test (CPET) and post-exercise recovery. This cross-sectional study involved 130 healthy Caucasian adult volunteers (71 participants with a history of COVID-19). All patients underwent the CPET with blood pressure measurements during exercise and post-exercise recovery. The post-COVID group had significantly higher systolic, diastolic, and mean blood pressure after 9 min of recovery and achieved a significantly lower max O2 pulse (2.02 mL/beat on average) than the controls. It should be noted that the COVID group tended to have higher blood pressure values in all steps, with no differences in heart rate, pulse pressure, and saturation at any step. The COVID-19 outbreak was associated with a higher blood pressure response, significantly, in post-exercise recovery, a lower maximum O2 pulse, and a lower maximum load achievement. Future studies are needed to determine if these abnormalities during the CPET and the blood pressure variation have prognostic value.

Not so good hybrid work model? Resource losses and gains since the outbreak of the COVID-19 pandemic and job burnout among non-remote, hybrid, and remote employees.

OBJECTIVES: The COVID-19 pandemic contributing to the dissemination of alternative work models such as fully remote or hybrid work models. The present study focused on these 2 types of unplanned changes in the working environment. The conservation of resources theory, the first aim of this study was to examine the predictive role of resource losses and gains since the outbreak of the COVID-19 pandemic in job burnout. Moreover, the authors investigated how non-remote, remote, and hybrid employees differ in resource losses and gains and job burnout. MATERIAL AND METHODS: A cross-sectional online comparative study was conducted a year after the outbreak of the COVID-19 pandemic. The respondents provided sociodemographic data, reported their current work model, and completed validated measures of resource losses and gains and job burnout: the Conservation of Resources Evaluation and the Oldenburg Burnout Inventory. Based on the data collected from 1000 working adults from the Polish population, the authors tested the differences in losses and gains of different categories of resources and job burnout components between the 3 groups of employees representing distinct working models, i.e., non-remote, hybrid, and remote. RESULTS: In general, the associations of losses and gains with job burnout subscales have been confirmed, regardless of the level of analysis of losses and gains. The authors' findings indicated that hybrid workers experienced significantly higher resource losses and gains (both in general and in different domains) in comparison to non-remote and remote workers. In turn, non-remote employees scored significantly higher on disengagement, which is one of the job burnout components. CONCLUSIONS: Hybrid workers experienced the highest levels of both resource losses and gains during the COVID-19 pandemic, compared to non-remote and remote workers, suggesting that this form of working arrangement involves the greatest changes in different life domains, bringing both positive and negative consequences for the employee.

Experience of COVID-19 disease and fear of the SARS-CoV-2 virus among Polish students.

Background: The SARS-CoV-2 virus pandemic has significantly affected individuals and entire societies. It has caused a number of adverse consequences for public health. It has contributed to lower average life expectancy and significantly reduced the sense of health security. It has affected not only physical but also mental health. COVID-19 infections have become so common in many countries, including Poland, that almost every member of society has either experienced it themselves or has a family member or friend who have been affected by the disease. The investigations undertaken in the article concern the fear of COVID-19 infection among Polish university students, determined by the experience of the disease -whether direct or among loved ones. Methods: An online survey was conducted with 851 students. It took place between 1 and 15 March 2021, a year after detection of the first case of infection with the virus in Poland. The aim of the study was to find out about the relationship between the experience of COVID-19 disease (whether direct or among people close to the respondent) and fear of this disease among university students in Poland. The analysis used intergroup comparison tests (Mann-Whitney U Test and t-test). Results: The results indicate that the level of fear of COVID-19 among Polish university students was low (M = 1.98; SD = .49), with women (M = 2.04; SD = .75) presenting statistically higher (t (620.46) = 3.05; p = .002) fear than men (M = 1.87; SD = .74). The situation of the respondent having had a close person fall ill with COVID-19 or die as a result of coronavirus infection was found to be significant for the level of experienced fear of COVID-19 in the studied group (t (469.46) = -2.98; p = .003). Conclusions: The significantly higher level of fear in the group of young people who knew someone close with severe (fatal) COVID-19 disease indicates that psychological support may be more significant for such people than for individuals who have not experienced such a situation. A similar conclusion can be formulated taking into account the gender criterion, as the results make it possible to predict that women expect more support in a pandemic situation.

Well-being of Polish university students after the first year of the coronavirus pandemic: The role of core self-evaluations, social support and fear of COVID-19.

BACKGROUND: The SARS-CoV-2 pandemic represents an unprecedented situation in the most recent history. It has had a number of negative consequences for individuals and for whole societies. Individual effects of the pandemic include not only loss of life and of physical health, but also deteriorated quality of life. OBJECTIVE: This study examines the effect of core self-evaluations (CSE), social support and fear of COVID-19 on the well-being of university students in Poland during the COVID-19 pandemic. METHODS: We conducted an online survey on a nationwide group of 1,000 students of Polish universities. The survey was carried out between 1 and 15 March 2021. The respondents filled out the following set of tools: World Health Organization Quality of Life Scale, Core Self-Evaluations Scale, Multidimensional Scale of Perceived Social Support and The Fear of COVID-19 Scale. RESULTS: The findings showed that core self-evaluations (CSE) were significantly positively associated with well-being in each of the four domains studied: physical health (r = 0.519), psychological (r = 0.763), social relationships (r = 0.465) and environment (r = 0.496). Similarly, social support correlated positively with physical health (r = 0.277), psychological health (r = 0.306), social relationships (r = 0.552) and environment (r = 0.496). Fear of COVID-19 correlated negatively with well-being in the domain of physical health (r = 0.188), in social relationships (r = 0.042) and with regard to the environment (r = 0.071), the correlations were weak. However, the relationship between fear of COVID-19 and well-being in the psychological domain was not confirmed. CONCLUSION: The findings point to the significant role of CSE and the role of social support in the perceived quality of life of young people during the pandemic. They provide valuable data concerning individuals who are particularly vulnerable to the adverse psychological effects at the time of the pandemic. They also prove that research conducted to explore other factors protecting individual well-being in difficult situations, including that of the pandemic, should be continued.

Mood Disorder Detection in Adolescents by Classification Trees, Random Forests and XGBoost in Presence of Missing Data.

We apply tree-based classification algorithms, namely the classification trees, with the use of the rpart algorithm, random forests and XGBoost methods to detect mood disorder in a group of 2508 lower secondary school students. The dataset presents many challenges, the most important of which is many missing data as well as the being heavily unbalanced (there are few severe mood disorder cases). We find that all algorithms are specific, but only the rpart algorithm is sensitive; i.e., it is able to detect cases of real cases mood disorder. The conclusion of this paper is that this is caused by the fact that the rpart algorithm uses the surrogate variables to handle missing data. The most important social-studies-related result is that the adolescents' relationships with their parents are the single most important factor in developing mood disorders-far more important than other factors, such as the socio-economic status or school success.

[The feeling of threat and stress: the mediating role of social ties in the workplace on the example of the mine rescuer occupation]. / Poczucie zagrozenia a stres − mediujaca rola wiezi spolecznych w miejscu pracy na przykladzie zawodu ratownika górniczego.

BACKGROUND: Working in high-risk occupations is associated with the feeling of threat and stress. The aim of the research conducted from December 2016 to May 2017 was to examine the relationship between these variables in the group of mine rescuers. It was assumed that the quality of social ties with co-workers would act as a mediator of the assumed relationship. MATERIAL AND METHODS: The sample consisted of 232 mine rescuers employed in emergency stations in Poland. The risk assessment at work was determined using Kwestionariusz poczucia zagrozenia w pracy (The Feeling of Threat at Work Questionnaire) by Mamcarz; Kwestionariusz poczucia stresu (The Feeling of Stress Questionnaire) by Plopa and Makarowski was used to study the feeling of stress, and the quality of social ties was measured using Skala wiezi spolecznych (The Social Ties Scale) by Skarzynska. RESULTS: A negative relationship was observed between the feeling of threat and the level of the experienced stress. The sense of social ties with co-workers acts as a mediator in the relationship between these variables. CONCLUSIONS: Social ties reduce stress caused by the feeling of threat, and they are also an important factor supporting the coping with negative emotions. The obtained results make it possible to present practical recommendations, aimed mainly at strengthening the adaptation and integration activities in teams carrying out their tasks in hazardous conditions. The authors of the study point out that these activities should concern primarily the following 3 areas: the adaptation of new members of the group, the strengthening of positive relationships in teams, and support in a traumatic situation during convalescence.
