Recent onderzoek toont aan dat tijdens de COVID-19 pandemie de mentale gezondheid afgenomen was, vooral onder jongvolwassenen. Psychologische flexibiliteit kan echter mogelijk de negatieve impact bufferen, met name tijdens stressvolle periodes zoals een pandemie. In de huidige studie werd getest of de mentale gezondheid het laagst was tijdens de pandemie – in vergelijking met de periode ervoor en erna – en dat dit met name voor jongvolwassenen (18-32 jaar) het geval was, ten opzichte van volwassenen (33-62 jaar) en ouderen (63+ jaar). Daarnaast werd onderzocht of mensen met een hoge psychologische flexibiliteit een betere mentale gezondheid hebben dan mensen met een lage psychologische flexibiliteit, met name tijdens de pandemie in uitdagende tijden. In een herhaald cross-sectioneel ontwerp werd data verzameld in Nederland vóór (2018, n = 531), tijdens (2020 & 2021, n = 3813) en na de pandemie (2022 & 2023, n =2143). Jongvolwassenen hadden een verlaagde mentale gezondheid tijdens de pandemie, maar de gemiddelde mentale gezondheid van alle deelnemers tijdens de pandemie bleef verrassend stabiel. Na de pandemie had iedere leeftijdsgroep een hogere mentale gezondheid dan tijdens én voor de pandemie. De mogelijke bijdrage van psychologische flexibiliteit aan de mentale gezondheid was tijdens de pandemie even relevant als na de pandemie. De kwetsbare mentale gezondheid van jongvolwassenen in crisissituaties moet in overweging worden genomen in de strategievorming van toekomstig crisisbeleid.Show less

Understanding the psychological and social factors that contribute to belief in conspiracy theories is crucial for managing the preventative measures and promoting evidence-based decision-making. However, the field of psychology has recently faced challenges regarding the replicability and robustness of research findings. This bachelor thesis aims to investigate the robustness and replicability of interaction effects in a study on beliefs in conspiracy theories and attitudes towards anti-coronavirus measures during the COVID-19 pandemic. The thesis extracts data from a study by Hudecek et al. (2022) on the psychological correlates of beliefs in conspiracy theories in Germany. Specifically, it examines the interaction effect between dark triad personality traits and social status in predicting belief in conspiracy theories. The thesis utilizes resampling to test the robustness of the interaction effects. The analysis includes three subsamples (random, central, extreme) with three dropout conditions (10%, 20%, 30%). F tests are conducted to assess the variance between two given methods. The results revealed that the distribution of the interaction coefficients remain fairly stable in the central resampling approach pointing to robustness, however, significant inconsistencies were observed in the random and extreme resampling approach. Future research calls for replicating the study in diverse populations, investigating additional predictors of belief in conspiracy theories and testing the robustness and replicability of previous findings to address the replication crisis in the social sciences.Show less

A growing number of research presents empirical evidence for the negative psychological consequences of the lockdowns, such as increased anxiety and stress. However, the long-term mental effects, especially on children and their parents, are unclear and need to be further investigated. Aims This paper aims to examine whether there is a difference in the levels of anxious and shy behaviour in five-year-old children and in parental stress in their parents due to the pandemic. Method The data was collected as part of the "Jij en Je Gezondheid" project, executed by the Gemeentelijke Gezondheidsdiensten region. Inclusion criteria included children around the age of five and their parents who live in Amsterdam. Independent samples t-test was run to investigate whether there is a difference in anxious and shy behaviour in the children and parental stress before and after the COVID lockdowns. Results Levels of anxious and shy behaviour were higher after the COVID lockdowns in children as compared to the before lockdowns group. Parental stress was reported to also increase after the COVID lockdowns. Conclusions The study emphasizes the negative effect of the COVID-19 pandemic on children’s anxious and shy behaviour and their parents' stress levels. The findings highlight the need for tailored interventions for families to decrease the long-term psychological burden of the pandemic, as well as additional research to fully understand the problem.Show less

Historically, Mexican organized crime groups have demonstrated strong resilience and overcome various challenges posed by the Mexican and American governments. However, it is not clear how the COVID-19 pandemic has impacted organized crime in Mexico. This thesis wishes to explore this by studying the changes in organized crime activity in Mexico before and during the pandemic. Based on the crime rates, it was observed that some organized crime-related activities decreased during the COVID-19 pandemic, while others remained stable. These results indicate that the COVID-19 pandemic and the subsequent regulations have had a slight, but insignificant impact on organized crime in Mexico. This strongly indicate that Mexican organized crime groups’ have the ability to show great resilience in the face of major disruptions to the social environment. This finding highlights the need for more detailed research on what mechanisms enable organized crime to remain afloat. An understanding of these mechanisms is of great significance to policymakers attempting to limit the harm of organized crime.Show less

University students are a vulnerable subgroup affected by the outbreak. It has adversely affected their academic and social lives. Previous findings indicate heightened anxiety, depression, and PTSD symptoms. Negative coping strategies such as alcohol consumption were used to overcome the effects of pandemic fear. The aim of the study is to investigate the link between pandemic fear and negative mental health issues, and alcohol use. Methods: The study had a cross-sectional design, involving 139 university students. Online self-report measures were used to assess pandemic fear, alcohol use, depressive, anxiety, and PTSD symptoms. The covariates age, gender, and educational level were controlled for in the statistical analyses. Multiple linear regression was used to examine the relationship between pandemic fear and depressive, anxiety, and PTSD symptoms. Moderated regression was used to examine the moderating effect of alcohol use on the above-mentioned link. Bonferroni correction was used to adjust alpha levels. Results: Pandemic fear was positively linked with depressive, anxiety, and PTSD symptoms among university students. However, although alcohol use might be used as a negative coping strategy, its moderating role on the link between pandemic fear and mental health outcomes was not statistically significant. Conclusion: Overall, as pandemic fear increased, mental health issues increased in university students. Future studies with longitudinal design and larger statistical power that considers other covariates, and has measures other than self-report might be more reliable in evaluating this further.Show less

This study aims to explore the leadership preferences among public servants during times of crisis, and to make concrete recommendations for further research into the underdeveloped knowledge on public leadership preferences in times of crisis. To do so, semistructured interviews were conducted with employees from the municipalities of The Hague and Gouda, during which they were asked to report their needs in terms of three leadership styles: laissez-faire, transactional and transformational. The study found that transformational leadership was preferred during the pandemic and encourages fellow researchers to verify this using quantitative means. Further recommendations include the reexamination of the usefulness of laissez-faire leadership and the usage of different leadership frameworks to touch upon other behaviors.Show less

The GEC was triggered in March of 2020 on the recommendation of the European Commission to give member states fiscal room to cope with the COVID-19 pandemic, but has remained in place for over three years, despite the subsiding of pandemic emergency measures, restored levels of economic activity, and the repeated recommendations and predictions from numerous European institutions that the rules were to be reinstated at the end of 2022 by the very latest. With the emergence of a legislative proposal from the European Commission to reform the SGP’s rules, questions have emerged from journalistic endeavours and academic literature as to the purpose of the extended suspension. This paper utilises explaining-outcome process-tracing as described by Beach and Pedersen (2013) to compare the expectations and assumptions of varying theories, particularly the “failing forward” theory of Jones et al., (2016) to investigate and explain the European Commission’s decision-making in the case of the SGP’s continual suspension. It concludes that the continual suspension can be minimally explained by ongoing reform efforts by the European Commission, in line with the theoretical expectations of Jones et al. and the findings of Schön-Quinlan and Sciponi (2017). It cannot rule out that the escalation of the Russo-Ukrainian War, and the economic knock-on effects, played a part in the decision for continual suspension. The findings of this paper have implications for understanding the European Commission as a fiscal actor in an economic crisis, and understanding the relevance of particular theories of European integration to the historical context of the COVID-19 pandemic.Show less

During the COVID-19 pandemic, populations in Western countries where the salience of the threat of the coronavirus was elevated, reported high support for preventive measures. This level of support did vary between countries which led to the question of whether the outcomes would be the same for previously excluded countries, like the Netherlands. Analysing how salience influences the support for NPIs can help governments with creating the best and most supported approach to battle contagious diseases in the future. For this research, the emphasis will be on the so far understudied Dutch population. Taking previous literature on the Netherlands and its neighbouring countries, this study argues that the salience of the threat of contagious diseases will increase Dutch citizens’ support for NPIs aimed at alleviating this threat. After conducting a survey experiment, no support was found for this hypothesis since both groups, with salience and without salience of the threat, reported an equal level of support for the implementation of NPIs. Overall, as expected from previous literature, the lowest support was found for implementing a complete lockdown. Unfortunately, these findings were not generalisable to the whole Dutch population. Future research should focus on either sampling a bigger group for a similar study, or on researching what does influence the support for NPIs in the Netherlands if it is not the salience of the threat of contagious diseases.Show less

Historically, Dutch mental healthcare has been slow to implement and utilise digital interventions, however, the new public health policies regarding social distancing presented an acute and emergent need to do so. Despite therapists’ concerns regarding its efficacy and potential technical challenges, countless mental healthcare professionals turned to videoconference therapy to conduct generalistic Basic Mental Healthcare outpatient treatments. This paradigm shift presented a rare opportunity to examine whether videoconferencing therapy yields comparable results to in-person interventions for common mental health disorders. Arkin, a large mental healthcare facility and research institute in central Amsterdam, collects routine outcome monitoring data for patients under its care, to support shared decision-making. For the purposes of this study, basic mental healthcare patients (N = 1392) were divided into three cohorts: Treatments performed prior to, treatments performed partially during, and treatments performed entirely during the COVID-19 lockdown; and pre- and post-test data were used to compare outcomes. Across the three cohort conditions, there were no differences in the treatment outcomes for videoconferencing therapy conducted during lockdowns, as compared to in-person interventions done prior to the COVID-19 pandemic, or blended treatments that had commenced as in-person treatment before the pandemic and then transitioned to videoconferencing during the lockdown. This observational study seems to indicate that videoconferencing and in-person therapies can produce similar clinical results in Basic Mental Healthcare patients with common mental health disorders, bolstering the findings of other meta-analyses and randomized controlled studies investigating this topic.Show less

To understand the implications of the proposed reforms by the EU Economic Governance Review, we conduct a case-study analysis of both COVID-19 Pandemic and the European Debt Crisis of 2009 to understand how efficient these proposed SGP reforms could be. The case-study analysis compares the public expenditures of member states to derive the efficiency of the Excessive Deficit procedure (EDP) under SGP. The author is able to derive limitations pertaining to policy failure in the analysis. Overall, even though the study might identify the subjective relevance of EDP amongst the member states, the procyclical impact of the reforms suggest further discourse in the field.Show less

With the rising survival number, investigating the long-term Health-Related Quality of Life (HRQoL) outcomes, which can be negatively influenced by depressive symptoms, became important. This study investigates whether there is a difference in depressive symptoms between COVID-19 and non-COVID patients that got admitted to the ICU; how depressive symptoms influence the HRQoL, and if there is a difference in HRQoL between COVID-19 patients and non-COVID patients; and if there is a relationship between the self-reported health, happiness, and satisfaction about the ICU stay and depressive symptoms. It was expected that COVID-19 patients would have a higher mean score on depressive symptoms than non-COVID patients, COVID-19 patients with depressive symptoms have lower HRQoL scores than non-COVID patients, and lastly, that there would be a negative relation between the self-reported health, happiness and satisfaction about the ICU stay and depressive symptoms. In this study, 278 patients participated. Approximately one year after ICU discharge, patients filled out a survey. For this study, the Patient Health Questionnaire (PHQ-9), the Euroqol Quality of Life (EQ6D), and general questions about the health, happiness, and satisfaction of the ICU stay were taken into account. An independent t-test demonstrated significant higher mean scores on depressive symptoms in COVID-19 patients than in non-COVID patients (p < .05). Regression analysis showed that depressive symptoms predicted HRQoL (p < .05), but HRQoL was not different between COVID versus non-COVID (p = .225). Regression analysis showed both health and happiness predicted depressive symptoms(p < .05), but not between satisfaction and depressive symptoms (p = .318). The results confirmed our hypothesis that there would be higher mean scores on depressive symptoms in COVID-19 patients than in non-COVID patients. Our findings are clinically relevant and can be used to provide better mental health care after ICU discharge. Follow-up studies should among other things focus on the length of ICU stay, the time during the pandemic that someone got admitted to the ICU, and the depressive symptoms two years after ICU discharge.Show less

Especially the demand for increased cross-national cooperation to accelerate data exchange for multilateral COVID-19 research to inform public health policy-making was highly critical. However, sharing health data for secondary purposes such as research is difficult, as technical, political, and ethical issues were identified before the COVID-19 pandemic. This thesis focused on data management issues and barriers such as a lack of metadata standards and data interoperability. Facilitating cross-border secondary use of health data to inform public health decisions has been on the EU's agenda for some time, leading to the creation of the Joint Action Towards the European Health Data Space and the European Commission’s recommendation on a European electronic health record exchange standard, among other things. The COVID-19 pandemic provided an excellent case study for determining whether these guidelines were adequate for guiding efficient data sharing in collaborative research. For instance, the EU made a significant investment in cooperative COVID-19 research projects with the goal of providing data to support public health policies. In this thesis, ReCoDID, ORCHESTRA, unCoVer, and SYNCHROS—four projects financed by the EU Horizon2020 program—are discussed in detail. The projects shed light on the challenges of sharing patient-level data from observational cohorts, particularly with regard to data management issues such as data interoperability. It was discovered that EU guidelines did enable the formation of research projects and that these projects were even aimed at improving data harmonisation and exchange in COVID-19 research. However, because there is still no EU-standardised agreement on the selection of data interoperability standards, this has become a difficult task. Specifically, none of the four projects examined was able to locate interoperability standards at the legal, policy, care process, information, application, or infrastructure levels.Show less
