The Assessment of Fear of COVID-19 among the Elderly Population: A Cross-Sectional Study

The prevailing COVID-19 pandemic has dramatically affected the mental health and well-being of individuals. This cross-sectional study aimed to assess the perceived fear of COVID-19 among older adults in Poland and identify subpopulations with the highest risk of potential mental health disorders. The study was conducted in November–December 2020 on 500 people aged ≥60 years (mean M = 67.9, standard deviation SD = 4.2). In order to collect information on participants’ characteristics and COVID-19-related information, they were asked to complete a questionnaire based on recorded telephone calls. Perceived fear of COVID-19 was measured using Fear of COVID-19 Scale (FCV-19S), which ranges from 7 to 35. Multiple linear regression was performed to identify factors associated with the perceived fear of COVID-19. Our results showed that the highest level of fear of COVID-19 infection was observed among women (p = 0.025) and patients taking anticoagulants (p = 0.004). Moreover, older adults with higher anxiety levels were more likely to be fearful of COVID-19 (according to the GAS-10 scale; p < 0.001). These findings may help policy makers and healthcare workers to adapt and implement better mental health strategies to help the elderly fight fear and anxiety during the prevailing pandemic.


Introduction
It has been almost 2 years since we first grappled with the COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Despite many attempts to reduce viral transmission, the development of vaccines, new diagnostic methods, antiviral drugs, and treatment strategies, the virus still continues to take its toll. To date, approximately 242 million people have been infected worldwide, while around 5 million of them died due to COVID-19 infection [1]. The clinical symptoms are cough, high fever, fatigue, and shortness of breath. The elderly, immunocompromised, and/or those with pre-existing chronic diseases are at the highest risk to develop severe respiratory problems, leading to multi-organ failure, pneumonia, and death.
The observed high morbidity and mortality of SARS-CoV-2 have triggered the fear of COVID-19 infection. As an example, in a survey of 44,000 participants conducted in Belgium in April 2020, the number of people who reported anxiety (20%) or depression (16%) had increased substantially compared to the survey conducted in 2018 [2].
Furthermore, changes in daily lives and behavior and the implementation of social restrictions also led older adults to have increased stress and anxiety levels affecting

Study Design
The survey was conducted in November-December 2020 during the second wave of the COVID-19 pandemic in a group of 500 people, including 290 women (58%) and 210 men (42%), aged 60 years and more (mean M = 67.9, standard deviation SD = 4.2). Respondents were asked to complete a questionnaire based on recorded telephone calls. The response rate was 40%. A stratified sampling per the demographic structure of a voivodeship was used to obtain a representative sample of the elderly population. The proper size of the sample using the following formula: where Z 1−a/2 is the standard normal variate (at 5% type 1 error p < 0.05), -1.96; p is the expected prevalence obtained from a pilot study, -0.4; and d is the absolute precision-0.043.
Target quotas were set for age and gender strata in each geographical region. The interviewers were properly trained and prepared to ensure the quality and accuracy of the interview. A data collection supervisor supervised all interviews, and a study coordinator randomly evaluated the recordings of the dialogue. The transcripts were not returned to participants for comment and/or correction nor were repeat interviews carried out. The duration of the interview ranged from 15 to 20 min. Participants provided their consent at the beginning of the interview. No compensation was provided for participating in the study. More details regarding the study design are shown in a previously published article [12]. The study was approved by the Bioethics Committee of Wroclaw Medical University.

Measures
To assess the fear of COVID-19 in the senior population, we used "Fear of COVID-19 Scale" (FCV-19S) [13]. Participants stated their position in a questionnaire using a five point scale, ranging from "1-strongly disagree", "3-neither agree nor disagree" to "5-strongly agree". Hence, the cumulative score ranged from 7 to 35, where the higher the score, the greater the fear of COVID-19. The answers to the Fear of COVID-19 Scale are presented in Table 1.
Participants stated their position in a questionnaire using a five-point scale (ranging from "1 = strongly disagree", "3 = neither agree nor disagree", and "5 = strongly agree"). Hence, the cumulative score ranged from 7 to 35, where the higher the scores, the greater the fear of COVID-19. The answers to the Fear of COVID-19 Scale are presented in Table 1.

Statistical Analysis
To investigate the associations between the COVID-19-related fears and sociodemographic factors, and different physical and mental health conditions among our study group, descriptive statistics were calculated for continuous quantitative variables, and the non-parametric significance tests (Mann-Whitney U test and Kruskal-Wallis H test) were applied for qualitative variables (nominal and ordinal). Adjusted beta-coefficient (β) and 95% confidence interval (95% CI) were reported for regression analysis. All analyses were performed using the statistical software package Statistica v.13.3 (TIBCO Software Inc. Palo Alto, CA, USA). The p-values presented in the tables take into account the Bonferroni sequential correction (Holm-Bonferroni Method). A p-value of <0.05 was considered to be statistically significant.
According to the ADL scale, most of the participants were fit people (493/500; 98.6%). However, according to the GDS-15 scale, a significant number of patients suffered from depression (176/500; 35.2%). They exhibited less social engagement (according to LSNS-6 scale; mean = 14.2 ± 5.9) and felt lonely (according to the Gierveld Scale, mean = 13.1 ± 1.8). Most of the participants had a proper nutritional status according to the MNA scale (418/500, 83.6%). Detailed data on the psychological characteristics of the surveyed people are presented in Table S3.

Fear of COVID-19 Infection
Many different factors contribute to the perception of fear and anxiety due to the prevailing COVID-19 pandemic, including sociodemographic factors, health conditions, and mental health. Based on the Fear of COVID-19 Scale (FCV-19S), we determined that 201 people were afraid of COVID-19 infection (201/500; 40.2%), and 89 participants were strongly afraid of COVID-19 infection (89/600; 17.8%). Eighteen people did not show any concerns about the pandemic (18/500; 3.6%); they did not care about the potential dangers of contact with other people. This result is in line with another question from FCV-19S, regarding feeling uncomfortable while thinking about COVID-19 infection. There were 220 participants who agreed (220/500; 44.0%) and 69 participants who strongly agreed with this statement (69/500; 13.8%). The fear of COVID-19 infection may be seen by the exhibition of different symptoms at different levels. Thus, other statements of FCV-19S included questions if patients' hands become clammy when thinking about COVID-19 disease or if they had insomnia or rapid heartbeat because of worrying about COVID-19.
However, according to our analysis, only 37 reported their hands become clammy when thinking about COVID-19 infection (27/500; 7.4%) and six people strongly agreed with this statement (6/500; 1.2%). Furthermore, 49 people reported suffering from insomnia, likely due to the threat of COVID-19 infection (49/500; 9.8%). For 14 people, it was obvious that insomnia was caused by the fear of getting sick (14/600; 2.8%). Fear of death caused by COVID-19 infection was observed in 94 respondents (94/500; 18.8%), and 34 people strongly agreed with this statement (34/500; 6.8%). The Fear of COVID-19 Scale also determined the impact of social media on the presence of anxiousness of COVID-19 infection. Watching news and stories regarding COVID-19 infection was the reason for the threat for 155 respondents (155/500; 31.0%). Participants' reported agreement on the seven items of FCV-19 Scale is shown in Figure 1. It is worth noting many respondents reported "Neither agree nor disagree" for all statements and questions included in the questionnaire (Table 1)

Figure/Table Legend, Error in Figure/Table
In the original publication [1], there was a mistake in the legend for Figure 1. The authors mistakenly translated the FCV-19S scale from Polish to English, confusing it with a scale of their authorship. The correct legend appears below.

Figure 1. Participants agreement on seven items of The Fear of COVID-19 Scale (FCV-19S).
In the original publication, there was a mistake in the legend for Table 1   Including all sociodemographic factors analyzed in this study, we determined the most critical predictor to exhibit fear and anxiety due to COVID-19 infection in the univariate analysis was the female gender (p = 0.025, Table 2). Women, regardless of age, were more often concerned about contracting COVID-19 infection than men. Furthermore, the fear of COVID-19 infection increased in respondents with a history of coronary heart disease (p < 0.001), COPD (p = 0.007), and heart failure (p < 0.001) ( Table 3). Including clinical characteristics of all respondents, we also determined that the number of medicines taken affects the fear of COVID-19 infection levels (p = 0.002). The most crucial predictors to exhibit fear were found in people who take cardiac drugs (0 < 0.001), antihypertensive drugs (p = 0.011), analgesics (p = 0.001), digestive ailments drugs (p = 0.005), anticoagulants (p = 0.004), and antidepressants (p = 0.043) ( Table 4). Including the physical state of the respondents, the fear of COVID-19 infection was primarily associated with lowered ability to perform complex activities (according to the IADL scale; p = 0.013), reduced mental acuity (according to the AMTS scale; p = 0.013), depression (according to the GDS-15 scale; p < 0.001), higher anxiety levels (according to the GAS-10 scale; p < 0.001), social isolation (according to the LSNS-6 scale; p = 0.006), and loneliness (according to the Gierveld scale; p = 0.004). Furthermore, respondents with the danger of malnutrition and malnutrition were more concerned about contracting COVID-19 infection (according to the MNA scale; p = 0.017) ( Table 5). A multivariate regression analysis was performed to select independent predictors of a high expected fear of COVID-19. Its results are presented in Table 6. The most crucial predictors to exhibit higher fear of COVID-19 infection levels are (1) female gender (p = 0.007), (2) anticoagulants (p = 0.041), and (3) anxiety levels (according to the GAS-10 scale; p < 0.001) ( Table 6).

Discussion
The rapid spread of the COVID-19 infection throughout the world has led to the increase of mental health crises, generated by the perception of stress, anxiety, depressive symptoms, insomnia, and anger. Older adults are at the highest risk of COVID-19 morbidity and mortality. The COVID-19 fatality rate for those over 80 years of age increases fivefold [15], and, hence, it is understandable they are at a higher risk of COVID-19-related fear and stress. The findings from our study showed a significant role of COVID-19 infection in perceiving fears among the older population in Poland, with a mean fear score of 19.3 ± 5.6 on a seven-item fear scale (fear score ranged between 7 to 35) (Table 4). Furthermore, we observed a great variety in participants' agreement of the COVID-19 fear scale (Figure 1), which may result from differential emotional responses to the prevailing pandemic. This phenomenon is likely due to the lack of compliance in the mass media about SARS-CoV-2 epidemiology, routes of transmission, prevention, and/or lack of sufficient knowledge and awareness of individuals about this viral disease [16][17][18].
Our previous study determined that 10% of all surveyed Polish elderly population (50/500; 10%) canceled planned hospitalizations due to the fear of COVID-19 infection. Untreated for chronic diseases, COVID-19-infected patients are at an increased risk of death. Thus, despite the paradoxical sincere willingness to reduce the rate of SARS-CoV-2 transmission, such situations may adversely affect the clinical health of patients [12]. In this study, instead of highlighting the consequences of the fear during the COVID-19 pandemic (e.g., changes in behavior), we found subpopulations that are at the highest risk to exhibit health anxiety during the current pandemic.
At first, we found that women are more frequently associated with higher stress, anxiety, and depression due to potential COVID-19 infection (p = 0.025; Table 2, and p = 0.007, Table 6). This finding is consistent with other studies reporting the gender differences in behavior caused by the prevailing pandemic [19][20][21]. The explanation of the gender-based heterogeneity in contributing fear of COVID-19 was reported by Hosen et al. [22]. Based on the cross-sectional study, they found more irresponsible behaviors towards the COVID-19 pandemic in males, which significantly decreases their consciousness about the potential infection of the virus. In contrast, women were more inclined to adjust to governmentimposed social restrictions, such as movement restrictions, covering the mouth and nose in public places, quarantining, or using disinfectants to reduce viral transmission. This behavior results from increased consciousness and, hence, potential fears of COVID-19 infection [22]. Furthermore, women are more susceptible to social isolation [23]. During the current pandemic, more women used psychological counseling than men, and these consultations focused mainly on emotional issues [24,25]. Women, especially elderly ones, as caretakers of families, are worried about themselves and their relatives, which intensifies the fear of COVID-19 infection.
Our study indicates that the fear of COVID-19 infection increases in people with pre-existing chronic diseases, such as coronary heart disease (p < 0.001, Table 3), COPD (p = 0.007, Table 3), and heart failure (p < 0.001, Table 3), which is consistent with other studies [26,27]. For instance, in a study aiming to assess the levels of fear of COVID-19 infection performed by Al-Rahimi et al., the significant predictors turned out to be the type of chronic disease including Crohn disease, hypertension, and cardiovascular diseases [28]. It is very likely that COVID-19 may affect the course of the pre-existing diseases and increase mortality because the overall stress caused by the viral infection may influence the cardiac muscle [29]. Furthermore, the study from the United States also reported that around one-third of infected patients with COVID-19 had at least one chronic disease; the most common were cardiovascular diseases, followed by chronic lung diseases and diabetes [30]. Thus, these results indicate the fear of COVID-19 infection in people, especially elderly ones, with cardiac and pulmonary problems is justifiable.
Furthermore, an important predictor of the fear of COVID-19 infection is also the number of prescribed medicines. The more drugs taken every day, the higher the levels of health anxiety caused by COVID-19 infection. This was observed mainly in people taking cardiac drugs (p < 0.001, Table 4), antihypertensive drugs (p = 0.011, Table 4), analgesics (p = 0.001, Table 4), digestive ailments' drugs (p = 0.005, Table 4), anticoagulants (p = 0.004, Table 4), and antidepressants (p = 0.043, Table 4). It is worth noting that people taking anticoagulants were the most frequently concerned about contagion during the COVID-19 pandemic (p = 0.041, Table 6). There is mounting evidence that COVID-19 causes abnormalities in blood clotting in the veins and arteries, leading to life-threatening strokes, heart attacks, and pulmonary embolism [31]. Thus, in this case, fears of COVID-19 infection are also justifiable.
Preventive measures to reduce the spread of COVID-19 transmission (e.g., lockdowns, social distancing, mask wearing, etc.) have paradoxically caused a wide range of negative consequences, including social disconnection, mental health problems, and lifestyle changes [32], leading to increased fear levels of COVID-19 infection. The US Centers for Disease Control and Prevention (CDC) estimates that, as of June 2020, nearly one-third of US adults were suffering from anxiety or depression [33]. This result is consistent with our analysis. The fear of COVID-19 infection was increased in people with weakened mental capacity (according to AMTS scale, p = 0.013, Table 5) and those feeling depressed (according to the GDS-15 scale, p < 0.001, Table 5), lonely (according to the Gierveld Scale, p = 0.004, Table 5), and with high levels of anxiety (according to the GAS-10 scale, p < 0.001, Table 5) and social isolation (according to the LSNS-6 scale, p = 0.006, Table 5). It is worth noting that the highest fear of COVID-19 infection was reported in those exhibiting a high risk of anxiety (p < 0.001, Table 6). The current literature confirms this result. For instance, Mistry et al., conducted a cross-sectional study among 1032 older Bangladeshi adults aged ≥60 years. They determined that fear of COVID-19 infection was higher among those who felt socially isolated [18]. This study, together with our findings, suggests that we should pay more attention to the psychological support of the older community members during the pandemic.
The rapid spread of the COVID-19 disease leading to high daily rates of new cases and deaths together with the bombardment of information to which citizens are submitted through the media can influence the development of mood disorders. This affects mainly the elderly population, which tends to spend more time watching the media (radio, television, newspapers) than younger people. Moreover, the inability to visit loved ones and be visited by them due to social restrictions also increases fear and anxiety [20]. According to our study, from a total of 500 patients, 190 of them declared that watching and reading news about COVID-19 on social media made them feel nervous and scared (155/500, 31.0% agreed; and 35/500, 7.0% strongly agreed with this statement) ( Figure 1, Table 2). The observed relationship between media exposure and the fear of the COVID-19 infection creates opportunities for policy makers and journalists to affect excessive worries. For instance, all information about SARS-CoV-2 epidemiology, prevention, and treatment should be provided unambiguously, without sensationalism and disturbing images. Furthermore, it is crucial to advise the elderly to restrict their exposure to media coverage of the COVID-19 crisis and avoid sensational media, which may increase stress and decrease the well-being of individuals [34][35][36].
As we are now after the third wave of the COVID-19 pandemic (late summer and autumn 2021) and including the fact that data were collected during the second wave (November-December 2020), the question appears if there are some changes in perceiving fears due to COVID-19 infection between these two different seasons. The first wave of the COVID-19 pandemic (spring 2020) raised the alarm in society, mainly because of the lack of knowledge about the pathogenicity and routes of transmission of SARS-CoV-2. The second wave identified the country differences in incidence, prevalence, and mortality rates of COVID-19. Although there was a significant impact of developed vaccinations, the third wave further exposed varying social and financial differences in different countries [37]. Several studies focused on the characteristics of effects of viral disease in different seasons [38][39][40][41], but no study highlighted changes in perceiving fears of COVID-19 infection during different waves. For instance, Iftimie et al. reported differences in age range and severity of the disease between two periods of COVID-19 infection (March-June 2020 and July-October 2020). Patients in the second wave were younger, and the duration of hospitalizations and case fatality rates were lower than those in the first wave. Furthermore, more children, pregnant and post-partum women, and people with renal and gastrointestinal symptoms were COVID-19 infected in the second wave than in the first wave of the COVID-19 pandemic [38]. It is worth noting that the analysis of the differential perception of fear of COVID-19 infection is quite challenging because different study groups referred to different periods as waves of the COVID-19 pandemic, depending mainly on the country where the study was performed.
To reduce the fear of COVID-19, it would also be beneficial to implement effective and informative campaigns about the disease, focused on its prevention. This solution could be crucial for the elderly population, which feels defenseless to face the problematic situation of the pandemic and is afraid to be COVID-19 infected. Furthermore, older adults should be provided with support plans with effective measures to improve their standard of living, eating habits, and living conditions [20]. This strategy may contribute to enhancing their ability to cope with the prevailing pandemic. It would be advisable for clinic authorities and health professionals to instantly design and implement measures to alleviate these effects, which harm the mental health of their patients. It is already determined that those who received COVID-19-related information from health workers had lower fear scores [18]. This result shows health workers are trusted among the older population and provide information in a sympathetic manner. Thus, the role of health workers in decreasing the fear of COVID-19 infection and enhancing the well-being among the elderly population is incontestable.

Limitations
Our study has some limitations. At first, data were obtained by completing the questionnaire based on recorded telephone calls and the response rate was relatively low, 40%. The second limitation is the cross-sectional nature of the study based on self-reports. This may limit the generalizability of our results to a wider population and claims about the directionality of the results. Additionally, the authors could not assess if there were any differences between those who did and did not reply to the telephone survey as no information regarding nonrespondents was available. Furthermore, respondents recalled answers to questions. These answers may be subject to recall bias. This increases the risk of overreporting or underreporting the actual fear of COVID-19 infection.

Conclusions
To the best of our knowledge, this is the first nationwide study providing important information about fear due to COVID-19 infection among Polish older adults. This study is relevant for policy makers and healthcare workers to determine subpopulations with the highest risk to react fearfully toward the prevailing COVID-19 pandemic and for journalists to be aware of the potential impact of their work.
