Abstract

The COVID-19 pandemic has resulted in the worst public health catastrophe in recent history, impacting people's mental health and increasing concern over vaccinations. Between early May and late June 2021, a web-based survey that included higher education institutions from three countries (Albania, Belgium, and Cyprus) was conducted. The purpose was to assess the impact of the COVID-19 pandemic on the mental health of academic staff, what affects their readiness to get the COVID-19 vaccine, and whether there is a link between the country of residence and readiness to be vaccinated. The short version of the Depression, Anxiety, and Stress Score (DASS) questionnaire and a section of questions on vaccination readiness supported by the Health Belief Model were used for data collection. The final study sample was composed of 87 academics, both in Albania (n = 57) and in European Union (EU) countries (n = 30). Females comprised 91.2% of the Albanian participants and 63.3% of the EU countries participants. 89.7% of Albanian participants reported significantly higher proportions of prior COVID-19 (p = 0.001), compared to only 10.3% of EU country participants. Participants from Albania were less likely to vaccinate family members against COVID-19, and there was a significant association between this finding and whether an institution was affiliated with the EU (p = 0.007). In the two study groups, the DASS indicators showed a significant association between stress (p = 0.012) and depression (p = 0.011). The findings indicated that the pandemic affected the academic staff's mental health. When compared to academic staff members working in the EU, Albanian participants exhibited a larger prevalence of moderate-to-extremely severe depression and stress, which had an impact on their intentions to vaccinate against COVID-19. The results are essential to developing mental health coping strategies and approaches for increasing vaccination uptake, especially in developing countries.

1. Introduction

The COVID-19 outbreak has triggered the largest global public health crisis since the SARS (severe acute respiratory syndrome) epidemic of 2003 [1]. Due to the situation, the World Health Organization (WHO) declared a pandemic on January 30, 2020. According to the WHO, there have been 474,659,674 confirmed cases of COVID-19 worldwide as of March 24, 2022, with 6,103,355 deaths and a total of 10,925,055,390 vaccine doses delivered [2]. The first COVID-19 vaccine, created by BioNTech and Pfizer, was recommended for use in the European Union (EU) on December 21 to prevent coronavirus disease 2019 (COVID-19) in individuals aged 16 and up, and the European Commission subsequently granted market authorization for use across the entire EU [3]. COVID-19 vaccinations have been shown to inhibit transmission and extend protection to those in close proximity to those vaccinated [4]. However, even bigger benefits exist if the population immunity threshold is reached and vaccine uptake increases [5]. Many people can be vaccinated but refuse to do so [6]. Fortunately, when COVID-19 vaccinations became available, there were some signs that vaccine hesitancy had decreased [7,8]. Before the vaccine, the most often reported reason for being unwilling to get vaccinated was a fear of adverse reactions to the COVID-19 vaccine [9]. In particular, adults from lower socioeconomic backgrounds are more likely to be hesitant or unable to accept a booster vaccine and, in turn, more likely to be seriously affected by the virus. Studies on the public perception of booster doses also showed this unwillingness to vaccinate, highlighting several relevant factors [10]. The scale of vaccination reluctance ranges from full acceptance to complete refusal of all vaccines. Some variables associated with a greater impact on vaccination uptake were confidence, belief in the need for or value of a vaccine, belief in the vaccine's supplier, and convenience [11]. Vaccine hesitancy was associated with a lack of trust in the COVID-19 vaccine's safety and scientific foundations and doubts about its effectiveness [12]. On the other hand, it is found that the COVID-19 pandemic was linked to extremely high levels of psychological discomfort, which frequently exceed the requirements for clinical significance worldwide. Being female, being part of the younger age group (<40 years), the presence of chronic or psychiatric disorders, being unemployed, being a student, and having regular exposure to social media or news on COVID-19 were some of the risk factors identified as related to distress measures [13,14]. In addition, these impacts were present in all countries independently, whether they were EU members or not. For example, studies in Cyprus identified a mental health burden for younger adults [15], with nurses reporting increased depressive and post-traumatic stress disorder symptoms compared to other healthcare professionals [16]. However, results from a cross-sectional study that included nurses and physicians from five hospitals in Belgium revealed a high prevalence of burnout, insomnia, depression, and anxiety among participants from the COVID-19 pandemic [17]. While another study identified the key factors that affected how many people in Belgium received the first dose of the COVID-19 vaccination. The COVID-19 vaccine was less likely to be received by immigrants, persons living alone, single parents, or people from socioeconomically disadvantaged groups [18]. According to a study of COVID-19 vaccinations in six European countries, vaccination hesitancy was more common in younger people, lived alone in smaller areas, and didn't have children. The hesitant profile, however, was linked to decreased institutional trust, a lack of COVID-19 preventive activities, and increased pandemic fatigue [19]. However, a survey conducted in the Western Balkans, including Albania, showed regional differences in the factors that influence social trust in the COVID-19 vaccination, showing the necessity for different strategies in communication efforts [20]. Despite this, vaccination significantly reduced the psychological distress linked to COVID-19, according to a new study [21]. Although the literature is rich in studies on the mental impact of the COVID-19 pandemic and vaccination readiness in various target populations, the academic medical staff lacks representation as a study population. To our knowledge, this is the first study comparing the benefits of getting vaccinated against COVID-19 by academic staff with a medical background in a non-EU country to those in EU countries.

2. Materials and Methods

2.1 Study Setting

We used data from a web-based survey that included academic staff members from four higher education institutions across three countries: Albania, Belgium, and Cyprus, the latter two of which are members of the European Union (EU), while Albania is a candidate. Participants in the study included full-time academic and research staff from Frederick University in Cyprus, Thomas More Health Care Campus Turnhout, Belgium, the University of Medicine Tirana (Faculty of Technical Medical Sciences), and the University of Vlore "Ismail Qemali," Faculty of Health in Albania. These educational institutions offer degree programs in health-related fields. The research partnership was established based on existing cooperation among the institutions involved in international programs, as well as active agreements and individual collaborations in national and international scientific research projects.

2.2 Study Design and Sample

Due to the breakthrough in the higher education system caused by the pandemic, all the countries involved were pursuing efforts to continue teaching and researching through alternative channels, mostly online; therefore, this study was conducted as a cross-sectional, web-based survey. The primary outcome of the survey was to assess the impact of the COVID-19 pandemic on the mental health of academic staff by better-understanding health beliefs and factors that affect their readiness to get the COVID-19 vaccine and whether to identify if there is a link between the country of residence, vaccine type, and readiness to be vaccinated in different European countries (EU and non-EU). The Cochran formula: n = (Za) 2 (p × q)/d2 was used to determine the sample size. Based on this formula, p = depression prevalence (according to Albanian, Belgian, and Cypriot studies, we took an average of about 11%) [14,15,17] q = prevalence complement, error margin = d, alpha = 95 percent significance level, and n = 2.85 × 2.85 (0.11 × 0.95)/0.1 × 0.1 = 92. According to the formula, 85 participants made the optimal sample size. Finally, 87 academic staff members were willing to participate in the survey. The response rate was 76% for the Faculty of Health, 85% for the Faculty of Technical Medical Sciences, Albania, 53% for Frederick University, Cyprus, and 46% for Thomas More, Belgium.

2.3 Questionnaire Development

The questionnaire was developed based upon consulting the pertinent literature review using the following elements: 1) socio-demographic data, 2) evaluation questions on the effect of COVID-19 on staff mental health using the short version of the Depression, Anxiety, and Stress Score (DASS) [22]; and 3) a section on vaccination readiness supported by Health Belief Model questions [23]. Selected data collection questionnaires are available in English, and since the questionnaire was administered in English, translation, reconciliation, and posterior validation in the local language weren't needed. Socio-demographic questions included age, gender, years of teaching, institution, conjugal status, advanced education degree completed, and other data suggested by the study research group that was considered applicable after approval by the external experts, who assessed each item separately. The selection of the DASS instrument was made due to the trustworthiness and proven validity of its use both for scientific research and clinical practice [24] in countries with different socio-economic and cultural backgrounds [25] as well as during pandemics [26]. The DASS is a quantitative measure of distress focused on three axes of depression, anxiety, and stress, with the rating scale as follows: 0 = Never; 1 = occasionally; 2 = frequently; 3 = almost always. Based on the score, each variable outcome (depression, anxiety, and stress) was classified as normal, mild, moderate, severe, and extremely severe. The Health Belief Model (HBM) [27] assessed readiness to get the COVID-19 vaccine. HBM is the theory that is most often applied to explain people's behaviors related to health. The model is based on six predictors of health behaviors, such as risk susceptibility, risk severity, benefits and barriers, self-efficacy, and cues to action. This theory is valuable for explaining behaviors and designing interventions [8,28]. This model was selected because the literature suggests that it has been widely used to explain people's behavior about receiving the COVID-19 vaccine [28,29], flu vaccine [30], and human papillomavirus vaccine [31,32]. The literature-based questionnaire contained 19 statements, including three general vaccine statements. The statements addressed participants’ perceived susceptibility and severity of the COVID-19 virus and their perceived benefits and barriers to the COVID-19 vaccination. Yes-or-no questions assessing past flu vaccination history (2 items) were also used to identify other cues to identify other cues to action. A four-point Likert scale (1 = very unlikely to 4 = very likely) was used for the two questions that directly asked participants about their intention to recommend or vaccinate their family members. All authors offered their expertise in designing and adopting the questionnaire, as well as its transition into Google Forms' electronic format for administration.

2.4 Data Collection

Data was collected between early May and late June 2021. The anonymous questionnaire was distributed in English to our colleagues' official e-mail addresses. Participants were recruited using the Google Forms platform and snowball sampling. The authors from each institution were the contact point and the reference for the data collection. The email was sent at different times to increase participation. Participants were asked to agree to the informed content by clicking a button at the beginning of the survey, failing which they were directed outside. The informed message explained that they would be asked to answer a series of questions and specified that all data would be treated anonymously. All the participants were able to complete the questionnaire once, and the survey was voluntary. The submission of incomplete questionnaires was avoided by making all the questions mandatory. Participants could not proceed with the next question or submit the questionnaire if all sections were incomplete.

2.5 Statistical Methods

Comparisons of characteristics between the study groups were made using chi-square (χ2) or Fisher’s exact test for categorical variables and the Mann-Whitney or Kolmogorov-Smirnov-Z test for continuous variables, as appropriate. Data were presented as medians accompanied by interquartile ranges (IQRs), where possible, or as numbers accompanied by their percentages. All normality assumptions were checked. Some variable categories were regrouped. For the selected variables, country and associated factors were presented. A p-value of 0.05 or less was considered statistically significant. An analysis of dichotomous outcomes was used to estimate the association between the different covariates and the following outcomes of interest: positive attitude about the effectiveness of the COVID-19 vaccine and the three-axis of the DASS, respectively, depression, anxiety, and stress. The Checklist reported results for Reporting Results of Internet E-Surveys (CHERRIES) [33]. The survey has been approved by the Research Ethics Committee (REC) of the Faculty of Health, the University of Vlore "Ismail Qemali," Vlorë, Albania, Decision No. 1, dated March 15, 2021. Every stage of the survey's design and implementation was guided by the Declaration of Helsinki's Ethical Principles for Medical Research Involving Human Subjects and the European Union's Ethics for Researchers. Before starting the survey, participants could read a paragraph in which the study goal and objectives were explained, including the risks and benefits of the participants as well as intended data use and management by the Declaration of Helsinki and the European Code of Conduct for Research Integrity.

3. Results

3.1 Sociodemographic Characteristics of Study Participants

Of the 150 invited subjects, only 87 completed the survey. The final study sample included in this analysis was composed of 87 academic healthcare professionals both in Albania (n = 57) and in European Union (EU) countries (n = 30) (14 from Belgium and 16 from Cyprus). Female participants comprised 91.2% of the Albanian participants and 63.3% of the EU countries participants. The majority of participants, both from Albania and EU countries, were married (77.2% vs. 76.7%). The educational background of Albanian participants was predominantly medicine (47.3%) and nursing (43.9%), while the majority of EU participants had a nursing background (56.7%). Most Albanian participants had a Ph.D. degree (43.9%), compared to 56.7% of EU participants with a postgraduate degree. The mean age of Albanian participants was 41.9, compared to 47.7 for EU participants. Table 1 shows the sociodemographic characteristics of the study participants.

Table 1 Sociodemographic characteristics of study participants.

3.2 COVID-19-Related Characteristics of Study Participants

Table 2 shows the COVID-19-related characteristics of study participants. 89.7% of Albanian participants reported significantly higher proportions of prior COVID-19 (p < 0.001), compared to only 10.3% of EU country participants who reported COVID-19. Among those vaccinated, the most common types of vaccines used among Albanian subjects were vector-based vaccines (72.5%), while mRNA-based vaccines comprised most of the vaccines received by EU-based participants (40%). There was a significant association between the two groups and how the type of vaccine affected their decision to vaccinate (p = 0.071).

Table 2 COVID-19-related characteristics of study participants.

3.3 Depression, Anxiety and Stress among Participants

Table 3 shows the level of depression, anxiety, and stress among participants about COVID-19. Depression (p = 0.006), anxiety (p = 0.011), and stress (p = 0.008) scores were significantly higher among Albanian academic healthcare professionals. The DASS indicators show significant associations between EU and non-EU participants in the study.

Table 3 Depression, anxiety and stress among participants.

3.4 Depression, Anxiety and Stress by Willingness to Vaccinate Family Members against COVID-19 among Participants

Table 4 shows depression, anxiety, and stress as measured by willingness to vaccinate family members against COVID-19 among participants. Among Albanian participants, some participants had expressed an unwillingness to vaccinate family members against COVID-19, while there were none among EU-country participants. Among Albanian participants, there was a statistically significant difference between the depression (p = 0.040) and anxiety (p = 0.039) scores of those willing and those unwilling to vaccinate their family members, with those unwilling having lower scores compared to those willing. This difference in scores was not observed for stress.

Table 4 Depression, anxiety and stress by willingness to vaccinate family members against COVID-19 among participants.

3.5 Depression, Anxiety and Stress among Those Who Were Unvaccinated but Willing to Vaccinate Family Members by EU/Non-EU

Table 5 shows depression, anxiety, and stress among those who were unvaccinated but willing to vaccinate family members, EU or non-EU. Even when the three indicators showed a severe to extremely severe score, no statistical association was found between depression, anxiety, and stress scores among study participants. Yet, EU-based professionals had lower but more variable depression, anxiety, and stress scores.

4. Discussion

We analyzed the data to evaluate the readiness of the academic staff included in the study to be vaccinated against COVID-19 and the effects of COVID-19 on their mental health. Most of the academic staff in the study were married. The academic staff from EU countries had a more extensive educational background in nursing, while the staff from Albania was a mix of doctors and nurses. As suggested by Table 1, there were significant associations between gender (p = 0.001), educational background (p < 0.001), and academic institutions in Albania and the EU, with a larger proportion of females in Albanian institutions and a larger proportion of other healthcare professions among the EU academic institutions. In this regard, the results of our study were in line with a similar study conducted in the Eastern Mediterranean Region, where female healthcare workers and those working in teaching hospitals had higher depression and stress scores due to the pandemic [34]. As shown in the results of Table 1 participants from Albania were significantly younger compared to their EU-based counterparts (p = 0.014). A study conducted in Belgium provided evidence that young people experienced high levels of mental distress during the COVID-19 pandemic [18]. While in Cyprus, as reported by a study, nurses were more likely than physicians to suffer from depression [16].

A characteristic of this study is that the academic staff from Albania had passed COVID-19 before the vaccine was available. The most common types of vaccines used among Albanian subjects (72.5%) were vector-based vaccines, while mRNA-based vaccines made up the majority of vaccines received by EU-based participants (40%). No statistical association was found between vaccine type and the need to be vaccinated. Differences were discovered for those who were willing to vaccinate family members. The unwillingness to vaccinate family members for COVID-19 was higher among Albanian participants (n = 12). There was a significant association between the willingness to vaccinate family members and whether institutions were EU- or non-EU-based (p = 0.007). No EU-based participant was unwilling to vaccinate family members, Table 2. A study that evaluated the willingness of academic nursing staff to be vaccinated evidenced their higher willingness than that of students, but with reservations mainly related to the uncertainty of the vaccine and the side effects associated with it [35]. There was a significant association between the two groups and how the type of vaccine affected their decision to vaccinate (p = 0.071). In this regard, the findings are consistent with previous research. Low acceptance and uptake were associated with low perceived benefits of vaccination and health concerns [36]. In contrast to studies conducted in Belgium among nursing healthcare workers, it was discovered that fear of unknown future effects and fear of side effects influenced vaccination uptake [37]. According to other studies, the national vaccination plan and the properties of new vaccines (such as their safety, side effects, effectiveness, etc.) play a major role in how well the COVID-19 vaccine is accepted [38]. The results of the assessment of depression, anxiety, and stress among participants about COVID-19 revealed moderate-to-extremely severe depression (p = 0.006), anxiety (p = 0.011), and stress (p = 0.008) scored significantly higher among Albanian academic health care professionals. When categorized according to the scoring criteria and further dichotomized, there was a significant association between depression (p = 0.011) and stress (p = 0.012) and the two study groups, with Albanian participants having a higher representation of moderate to extremely severe depression and stress (Table 3).

These results contrast with those of a longitudinal study among seven European countries, which found that in all waves of COVID-19 the participants had probable depression and anxiety, even if at a low or moderate rate [39]. At the same time, a study of healthcare workers in Albania discovered that mild anxiety and moderate depression were expressed, similar to the results of our study [40]. Depression, anxiety, and stress as measured by willingness to vaccinate family members against COVID-19 among Albanian participants appeared statistically significant for the depression (p = 0.040) and anxiety (p = 0.039) scores of those willing and those unwilling to vaccinate their family members, with those unwilling having lower scores compared to those willing. In this regard, our results are inconsistent with the literature. A study revealed that having a postgraduate degree is associated with fewer concerns and a greater willingness to vaccinate [41]. But in our study, the Albanian participants in Table 1 had more postgraduate and PhD degrees than EU participants. Similar worries about vaccinating family members are more closely tied to the safety and effectiveness of the vaccination [42]. Also, a study has revealed different factors for being unvaccinated and for delaying the COVID-19 vaccination. Unvaccinated appears linked to a general mistrust of preventative efforts [43]. Depression, anxiety and stress among those who were unvaccinated but willing to vaccinate family members by EU or non-EU, Table 5 measured a severe to extremely severe score with no statistical association among study participants. EU-based academic professionals had lower but more variable depression, anxiety, and stress scores. Depression, anxiety, and stress were common among unvaccinated but willing to vaccinate family members, EU or non-EU. Table 5 revealed a severe to extremely severe score with no statistical association among study participants. EU-based academic professionals had lower but more variable depression, anxiety, and stress scores. According to a study, participants who had received the COVID-19 vaccine had a 25% higher likelihood of reporting both anxiety and depression than those who had not received the vaccine [44]. However, the research points to social anxiety as a significant element connected to COVID-19's impacts and attitudes toward vaccine compliance [45]. The results of our study, particularly for the unvaccinated Albanian participants, can be explained by the fact that most of them got the COVID-19 infection prior to vaccination (Table 1). Evidence from a study supports this fact. It is suggested that psychological distress before to infection could be a risk factor for post-COVID-19 disorders involving mental health symptoms [46]. Finally, a multinational study stated that inadequate or inaccurate information that fails to adequately explain the advantages and disadvantages of the available vaccines might also contribute to vaccine hesitancy [47].

5. Limitations

Our study has several limitations. First, our study population was small and predominantly Albanian compared to participants from other EU countries. The nonrandom study population and the web-based survey type may introduce bias into the study. Also, the different educational backgrounds of the academic staff involved in the study might have contributed to biased results. In addition, since the sample's mental state before the pandemic was unknown when it was tested, this cross-sectional methodology doesn't reveal anything about how the results for mental health have changed over time. All of the factors above limit the external validity of the data and the extent to which our study's findings can be generalized. Nevertheless, our study has several strengths. Depression and anxiety were measured using validated scales. We assessed perceived stress and worried about COVID-19 and the need to be vaccinated in an unstudied target population group, such as academic staff with a medical background. Knowing how people perceive stress and depression about the pandemic in European countries with different socio-economic, cultural, and health systems adds value to developing preventive and support strategies for academics who disseminate knowledge to the general population.

6. Conclusions

To conclude, various determinants contributed to COVID-19 mental health impact and vaccination hesitancy in a sample of academic staff from three European countries (EU and non- EU). The three indicators of mental health impact analyzed, such as depression, anxiety, and stress, showed a severe to extremely severe score even if EU-based academic staff had lower but more variable depression, anxiety, and stress scores. The study found that the academic staff from Albania expressed more severe depression, anxiety, and stress scores. Considering the small sample size in the study (Belgium and Cyprus), it was found that the profile of the COVID-19 vaccine-hesitant in Albania is a person of a younger age, with Ph.D. degrees, and with greater reluctance to vaccinate their families against the COVID-19 vaccine. Furthermore, even if they had the COVID-19 infection prior to the vaccine's rollout, the Albanian academic staff were significantly more prone to psychological distress. The findings are essential for developing vaccination uptake and mental health coping strategies, especially in developing countries. Further research in the form of large-scale studies which also more closely consider the socio-demographic and economic profiles of each country could be beneficial in creating a complete picture of the impact of the pandemic on the mental health of healthcare professionals in particular.
