Preparing for the Worst? Household Food Stockpiling during the Second Wave of COVID-19 in Serbia

Stockpiling and panic buying are significant components of crisis- and disaster-related consumption behaviors that have gained significant media coverage during the COVID-19 pandemic. This paper aims to analyze the features of stockpiling behavior during the second wave of COVID-19 in Serbia based on a structured online questionnaire. This study seeks to answer two questions. First, what factors triggered and affected stockpiling during the COVID-19 pandemic in Serbia? Second, how does stockpiling affect other food habits and diets? A total of 851 valid responses were received. The results highlight several features of the stockpiling behavior in Serbia. First, food stockpiling behavior is influenced by some sociodemographic variables such as gender and household composition. Second, stockpiling was fueled by several negative emotions such as fear, sadness, and depression. Third, the results confirm that stockpiling in Serbia was not triggered by supply shortages but rather by consumers’ concerns of obtaining enough food and rising food prices. Finally, food stockpiling was associated with some positive changes such as eating out less (e.g., restaurants/cafeteria), eating more with their family members, and cooking more food. Analyzing and comprehending consumer food stockpiling patterns during the COVID-19 pandemic may offer policymakers imperative information for adjusting supply and response strategies during future crises.


Introduction
Consumers are subjected to systemic tension and stress during unstable circumstances such as wars, recessions, and natural catastrophes, resulting in the development, expansion, or modification of their behaviors [1,2]. The global COVID-19 pandemic is a stressful situation that has impacted the lifestyles and behaviors of the population suddenly and dramatically and will continue to have a broad direct and indirect influence [3]. Aside from the necessary enhanced focus on human health, concerns emerge about the pandemic's effect on food systems [4,5]. The COVID-19 pandemic and associated containment measures, including mobility restrictions, social distancing, and lockdowns, significantly prejudiced diet, daily food patterns, and general functioning of food systems [6,7]. The pandemic has also affected food shopping patterns: Stockpiling, online shopping, etc. [8][9][10][11][12][13][14].
Stockpiling and panic buying are significant components of crisis-and disaster-related consumption behaviors that gained significant media coverage during the COVID-19 pandemic [15]. Indeed, during a crisis, food becomes more fundamental to the consumers' lives, and panic purchasing is a normal human response to this stressful situation. Panic buying and stockpiling were shaped by several factors, including sociodemographic factors (e.g., culture, income, gender, and personality). This compulsive buying has several adverse effects, such as increasing food prices [16], food wastage, and stock out [17], and exacerbates overconsumption (cf. obesity) and unequal food access for some vulnerable groups (e.g., poor, elderly) [18][19][20]. Understanding the interaction between these several factors is crucial for enhancing the efficiency of crisis and disaster management, as well as human and economic resilience to current and potential crisis events. Understanding consumer food hoarding during the COVID-19 pandemic may also offer governments and policymakers vital information for readjusting inventories and reaction strategies [21].
As of 15 May 2021, Serbia has confirmed 705,185 confirmed cases of COVID-19 with 6646 deaths [22]. On 6 March 2020, Serbia confirmed its first case of COVID-19 [23]. As a result, on 15 March, a state of emergency was announced. Later, Serbia adopted several containment interventions to stop the virus: Nationwide lockdown, closure of non-essential businesses, shutting of schools and universities, remote work, etc. [24,25]. On 4 December 2020, the government implemented tighter COVID-19 measures in response to a rising number of infections. Nevertheless, these measures may have influenced food-related attitudes and behaviors, such as stockpiling [26]. According to the Serbian daily newspaper, Danas, Serbian consumers spent RSD 2 billion (€17 million) more on food, drink, personal care, and housekeeping products in the three weeks ending 15 March 2020, compared to the same period in 2019. Sugar has emerged as one of the most sought-after items, followed by flour. The demand for frozen vegetables, canned tuna, eggs, pasta, frozen pastries, and edible oil also increased significantly [27]. Meanwhile, leading retail chains witnessed a 20% increase in household consumption. Furthermore, during March 2020, the opening hours of supermarkets in Serbia were reduced to contain the spread of the SARS-CoV-2 virus [27]. Some previous research confirmed that the COVID-19 pandemic changed Serbia's food consumption, food shopping, and food [26,28,29]. However, not much is known about stockpiling behavior during the pandemic and the factors behind it. Moreover, the number of studies on stockpiling in the Balkan region is very limited. In fact, academic research on the effects of the COVID-19 pandemic on food systems and consumption habits has been geographically biased, with a concentration on Western and Southern Europe, North America, and China [13,30], while developing and Balkan countries in general, such as Serbia, have been overlooked. Further, since the COVID-19 pandemic is new and we do not know how long it will continue, there is a need for information and expertise to evaluate its effects on food behaviors and purchasing habits.
Accordingly, this study aims to fill this knowledge gap by analyzing the features of stockpiling behavior during the COVID-19 pandemic in Serbia. To our knowledge, it would be the first study of its kind in Serbia and the whole Balkan region. It seeks to answer two questions. First, what factors triggered and affected stockpiling during the COVID-19 pandemic in Serbia? Second, how does stockpiling affect other food habits and diets? Before presenting and discussing the research results, we describe the methodology.

Panic Buying and Consumption Changes during Crises
Panic buying is defined as a "phenomenon of a sudden increase in buying of one or more essential goods in excess of regular need provoked by adversity, usually a disaster or an outbreak resulting in an imbalance between supply and demand" [31] (p. 100). Unmatched panic buying dominated headlines during the early days of COVID-19 in 2020 in several countries just after confirming the first coronavirus cases. Panic buying (PB) has been reported recently with the COVID-19 pandemic, but it has existed for a long time. Panic buying is an unusual social behavior that has been seen in times of crisis and emergency [32]. External traumatic crises and events such as wars, recessions, natural catastrophes, and pandemics have caused the start, intensification, or changes in consumer habits as a means of coping with stress throughout history [1]. Disasters and crises clearly influence consumption behaviors [33]. Previous research has shown panic buying as a common reaction to environmental stresses or during stressful and uncertain times [34]. Indeed, several recent disasters demonstrated risk-averse consumer behavior [35]. These behavioral changes may have an impact on food intake attitudes and behaviors [36]. Panic buying and stockpiling are shaped by several factors.
Firstly, panic buying and stockpiling seem not triggered by supply shortages but rather by consumers' fears and anxieties of a potential shortage [37][38][39]. Additionally, food purchases are a behavioral response to stress and anxiety. During a stressful situation, perceived loss of control is unpleasant and motivates consumers to reclaim control over product procurement [40]. Stockpiling storable food products provides consumers with a feeling of control over the perilous situation generated by the crisis [41]. The lack of information about a health crisis influences dread of the unknown. It generates ambiguity, which leads individuals to ponder and envision various scenarios, causing anxiety [42]. Fear, rather than the epidemic itself, is often shown to influence purchasing behavior [37,38,43]. As the awareness of the virus and its possible severity was minimal at the outset of the outbreak, consumers all over the world, concerned about the long-term outlook, focused on impulse shopping and stockpiling storable food products (e.g., flour, pasta, canned items, rice, etc.) to mitigate the risk of future shortages [44,45].
Secondly, during a health disaster, people develop risk perceptions about the situation. According to Sheu and Kuo [46], panic buying before or after a catastrophe is a kind of self-protection behavior or deliberate action to reduce risk. Therefore, when there is a high perception of threat, an individual may stockpile food to reduce the danger of contracting the disease [47]. According to several studies, the potential threat of being infected with the virus affects consumer behavior when shopping for food. Thus, despite many protective measures and regulations applied by supermarkets (e.g., the installation of protective barriers at cash registers, frequent cleaning, the limitation of the maximum number of shoppers at one time, provision of masks, gloves, and disinfectants, etc.), for many consumers, shopping at a grocery store poses an evident danger [48,49]. Accordingly, some consumers stockpiled food to make fewer grocery-shopping visits and spend more on each trip to limit supermarket visits, thus reducing their potential risk of COVID-19 exposure [17]. Panic purchasing may, in this respect, be seen as a self-protection strategy to meet safety requirements [47].
Thirdly, panic buying is linked to perceived scarcity. Therefore, a product that is expected to become unavailable soon owing to a health issue may threaten or restrict personal freedom (i.e., prevented or reduced access to the product) [50]. This would thus trigger psychological responses and an urgent need to purchase and hoard behavior [51].
Fourthly, since consumers are members of a society, which could influence their decisions, panic buying is "contagious". According to Grasso [52], the fear of scarcity is self-fulfilling; the more individuals hoard, the more others are affected by the panic, and the quicker the food runs out. The media narrative could also aggravate this behavior. The dissemination of stories, pictures, and videos depicting individuals fighting in the aisles over products and shoppers lining up early in the morning to buy essential items on social media worsened this behavior [53]. Restaurants shut simultaneously, and people started to depend nearly entirely on groceries for their meals.
Finally, panic buying and stockpiling were shaped by several factors. Household preferences and attitudes and product types may be adjusted differently through time [54]. Overall, individuals in different age groups have responded differently to the health crisis [55]. However, these changes often depend on more extensive factors than individuals and are more tightly linked to local, national, and global decisions and policies [56]. For example, according to Prentice et al. [57], government measures related to COVID-19 are linked to panic buying in Australia. Panic buying began shortly after the first coronavirus cases were confirmed and rose significantly as the lockdown was expanded and social distancing measures were tightened.
This compulsive buying has several negative consequences, such as increasing food prices, food wastage [28], and stock out [17], and exacerbates overconsumption (cf. obesity) and unequal food access for some vulnerable groups (e.g., poor, elderly) [18][19][20]. Such behaviors alter the regular market by emptying shop shelves, inconveniencing other consumers, and sending panic and fear signals to society [58]. Likewise, panic buying increased household food waste generation, especially for perishable products, due to storage limitations, bad cooking habits, or overcooking [17,59]. Furthermore, panic buying disrupts supply chains [60]. Since the food distribution system is based on just-in-time, with fast-moving and low inventory levels, the sudden and unanticipated increase in demand resulted in short-run stock-outs, jeopardizing the stability of the food system [33,61,62].

Data Collection and Questionnaire Design
The study was based on an online survey conducted in Serbia. The survey was administered in Serbian from 14 November until 10 December 2020. The survey was created using the Survey Monkey platform and circulated through social media (e.g., Twitter and Instagram). The study used the non-probability and the snowball-sampling technique [63,64]. Participants were asked to distribute the questionnaire to their friends and relatives. The study targets the broad adult population in Serbia (age > 18 years).
This study is part of the international research project "Consumer Agency, Food Consumption Behavior, and the Novel Coronavirus (COVID-19) Outbreak" sponsored by the Food Industry Research and Education Center (FIRE) at Western Michigan University [65]. The Western Michigan University Human Subjects Institutional Review Board (HSIRB) approved all research survey procedures. The Food Consumption Changes 2020 survey of West Michigan University [65] and the COVID-19 Survey of the United Nations System Standing Committee on Nutrition (UNSCN) [66] informed the questionnaire used in the online survey. The same survey, based on the same questionnaire, was conducted in several countries in the Middle East region, such as Qatar [67], Morocco [14], and Lebanon [13], and in Europe, such as Russia [68] and Bosnia [69].
The questionnaire comprised 24 different questions (multiple-choice, one option), split into three parts (Appendix A). The first section of the questionnaire included questions about the respondents' sociodemographic features, such as education level, gender, income, etc. The second part collected data on food purchase and consumption behavior during the COVID-19 pandemic, such as grocery shopping frequency-including panic buying and hoarding, diet, fears during grocery store visits, food waste, etc. Finally, the third section included questions about the positive (e.g., calm, optimistic, excited, etc.) and negative emotions (e.g., sad, bored, scared, etc.) experienced throughout the epidemic.
Two phases preceding the questionnaire distribution were completed. To first enhance the validity and reliability of the research, an expert panel performed a qualitative substance validity analysis. Based on the expert's opinion, irrelevant elements have been removed, and the rest have been amended to make them more effective and precise. Secondly, a pre-test with 25 participants to verify data precision and information was conducted before administration to improve the survey questions. As a consequence, 851 valid responses were received from which 351 respondents stockpiled food.

Data Analysis
SPSS (Statistical Package for Social Sciences) version 25.0 was used to analyze the survey results. Descriptive statistics (percentages and frequency distributions) were generated. Multiple answers were analyzed to deduce the percentages of answers and cases. Furthermore, the chi-square test was used to evaluate the association between variables since variables were examined on a nominal scale. In addition, logistic regression was applied to predict the dependent variable (stockpiling behavior) according to predictor variables. Non-parametric tests were used. Since there were only two groups, a binary logistic model was applied. The stepwise procedure was applied to estimate the model (seven steps were forwarded to find the most appropriate predictors for this study).
The probability of a 'yes' answer is P, as shown in Equation (1) below. B is the constant regression term, and B ji s is the regression coefficient for X j , which is a predictor variable with j = 1, 2, ..., j. The results section presents estimates b for the beta and the value exp (B) to ease the interpretation. This value indicates a shift in odds when the relevant predictor variable rises by one unit and the dependent variable is 1.

Sociodemographic Characteristics of the Study Participants
The sociodemographic characteristics of the respondents are described in Table 1. The findings indicate that 68% of the respondents are women, and 32.31% are married with children. Additionally, most of the respondents were middle-aged (44.77% were 25 to 45 years old), and 48% earned a higher income than other Serbian households. Overall, the sample was highly educated, as 78.26% possessed a university degree, master's, or Ph.D. In contrast, only 21.75% had a secondary school diploma or no qualifications. In terms of occupation status, of all the interviewees, 74.15% were working (full-time or part-time), 20.33% were students, and 9.82% were unemployed and searching for jobs (Table 1).

Stockpiling Dynamics during the COVID-19 Pandemic
The survey results highlight different, sometimes divergent, dynamics about food stockpiling behavior among Serbian households during the second wave of the COVID-19 pandemic.
Firstly, consumers who stockpiled food had a different shopping behavior. They made fewer grocery-shopping visits and spent more on each trip to limit supermarket visits. Indeed, 38.18% of the participants who stockpiled food made fewer grocery-shopping visits than usual compared to 26.6% for those who did not stockpile food. In addition, 40.74% of those who stockpiled food spent more than usual on each trip to limit supermarket visits, compared to 10.2% for those who did not stockpile food (Figure 1). These results suggest that many Serbians made recourse to panic buying as a kind of self-protection behavior [46] and a deliberate action to reduce the risk of contracting the disease [47] by reducing the number of trips to supermarkets and shops. Indeed, the survey shows that many Serbian consumers stockpiled food to make fewer visits to shops while spending more time on each visit/trip, thus reducing their perceived potential risk of COVID-19 exposure [17,48,49,70]. Second, as indicated in Figure 2, stockpiling during the COVID-19 pandemic was fueled by negative emotions such as fear, sadness, and depression. Indeed, participants who stockpiled food felt more nervous, worried, and/or sad than those who did not. Further, the results confirm that stockpiling is not triggered by supply shortages but rather by consumers' fears and concerns of a potential shortage. Indeed, 24.22% of the participants who stockpiled food were concerned about obtaining enough food compared to 5.6% for those who did not stockpile food. In addition, 31.62% of the participants who stockpiled food were concerned about food prices rising, compared to 19.06% for those who did not stockpile food (all by including levels 4 "very concerned" and 5 "extremely concerned") ( Figure 3). As Hansman et al. [71] underlined, this behavior has some economic explanations. Indeed, a crisis often leads to higher predicted future prices, making the current price appear as a "deal" requiring stockpiling as the optimum behavior. These results align with those obtained by Tsao et al. [39] and Maghsoudi et al. [50], who argue that panic buying and stockpiling seem triggered by consumers' fears and anxieties of a potential, perceived shortage, rather than an accurate and effective food shortage. Therefore, feelings, emotions, and perceptions (that can be fueled by social media or even 'fake news') are essential determinants of panic buying. This clearly shows the importance of effective communication during crises and emergencies [42,43], such as the COVID-19 pandemic. Communication at the onset of crises is fundamental to prevent panic buying as this 'social' behavior seems quickly 'contagious' [52,53] and can degenerates in a short time if not managed in an effective and timely way. However, as for any government measure or intervention during the COVID-19 crisis [56,57], communication and awareness-raising campaigns should be well targeted in order to yield the expected results. Such campaigns should also highlight the many negative impacts of panic buying and stockpiling on agrifood markets and supply chains [17][18][19][20]33,58,[60][61][62] and, consequently, food availability and accessibility for consumers themselves. Third, the results confirm that stocking food products provides customers with a feeling of control over the perilous situation generated by the actual health crisis. Indeed, 35.9% of the participants who stockpiled food indicated that this behavior makes them feel more secure, 24.5% indicated that it comforts them, and 30.5% indicated that it gives them a sense of control (all by including levels 4 and 5) (Figure 4). These results suggest that panic buying and stockpiling are behavioral responses to negative feelings and emotions such as stress, fear, and anxiety and a way for consumers to reclaim control over product procurement [40]. Indeed, stockpiling food provides consumers with a feeling of control [41].

Stockpiling and Food Activities during the COVID-19 Pandemic
The behavior of the participants who stockpiled food was different compared to those who did not. Firstly, 40.74% of the respondents who stockpiled food ate more with their family members, 56.7% cooked more food, and 18% made more easy meals (e.g., instant foods, frozen foods, etc.) than usual, compared to 27.6%, 38.2%, and 10.4% for those who did not stockpile food (all by counting "moderately more" and "much more" answer options).
Secondly, 63.25% of the respondents who stockpiled food ate less out (e.g., restaurants/cafeteria/fast food), and 28% ordered fewer take-away or fast-food meals with deliveries than usual, compared to 54.6% and 18.8% for those who did not stockpile food (all by counting "slightly less" and "much less" answer options). However, 31.05% of the respondents who stockpiled food ate between meals (snacks) compared to 17.8% for those who did not stockpile food (all by counting "moderately more" and "much more" answer options) ( Table 2). Further, the Chi-square test result shows a meaningful association between stockpiling food and food waste behavior (χ 2 = 23.72, p < 0.01). Thus, stockpiling food did not increase food waste. In fact, for 34.61% of the respondents who stockpiled food, their waste became less compared to 25.8% for those who did not stock food (by including "It has become much less" and "much less" answer options) ( Figure 5). These results are in agreement with those obtained by other scholars [17,59], who argue that panic buying and consequent food stockpiling increased household food waste generation, especially for perishable, short shelf-life products (e.g., fruits, vegetables, etc.). The reasons behind such an increase may be related, among others, to cold storage limitations and bad conservation/preservation conditions. Accordingly, stockpiling food did not increase food waste in Serbia during the pandemic. In other words, the increased food purchases during the pandemic did not increase food waste. This may imply that, since the coronavirus outbreak, Serbian consumers have adopted a broad range of positive food management strategies, such as better food shopping planning, enhanced in-house food storage, and enhanced use of leftovers. This points to an encouraging shift toward more sustainable food consumption habits. Overall, household food waste in Serbia is low, as in most developing countries in the Balkan region [72][73][74]. However, there is no accurate information on how much food is wasted in Serbia. According to National Geographic Serbia [75], 35 kg of food is thrown away per capita per year. Djekic et al. [76] suggest that, annually, Serbian households discard 198,712 tons of food waste associated with 687,346 tons of CO 2 emission. As has been observed in many countries, such as Italy [77], Russia [68], or Qatar [67], the COVID-19 pandemic has induced a positive behavioral shift in food waste in Serbia.
Furthermore, the logistic regression analysis results revealed that the overall predictive power of the model was 78.4%, while the substantial Chi-square (p < 0.01) showed the strength of the model, and 78.4% of the respondents were grouped correctly. In logistic regression, the value of the -2 log-likelihood statistic is widely used to measure the goodness of fit of the model (−2LL = 772.26). This statistic behaves like Chi-square, and when the estimated logit model fits with data well, its value decreases. The decrease is equal to the decrease in the improved Chi-square and the Chi-square model. The decline from 292,73 to 4.14 in the value of this figure showed the fit of the model. According to Nagelkerke R2, the variables included in the model accounted for 47.1% of the variation in the calculated variance. As a result, the estimated logit model could estimate a modest proportion of the dependent variable's values using the variables in the equation (e.g., obtaining enough food, food prices rising, food spreading COVID-19, etc.) ( Table 3).
According to the b coefficients, seven influencing factors out of sixteen entered the equation that may substantially impact the willingness to stockpile food. There was a significant positive relationship between several variables such as obtaining enough food, "stocking up on items makes me feel more secure", "stocking up on items gives me a sense of control", etc., and the dependent variable, willingness toward stockpiling behavior. By contrast, there was a significant negative relationship between the dependent variable "willing toward stockpiling behavior" and the variables "food prices rising" and "stocking up on items comforts me". Exp(B) values are the odds ratios for the predictors. They are the exponentiation of the coefficients. According to Exp(B) values, the highest effect was that stocking up on items makes me feel more secure (2.295), stocking up on items gives me a sense of control (1.907), and obtaining enough food (1.502) ( Table 3). These results confirm that stockpiling is not triggered by supply shortages but rather by consumers' fears and concerns of a potential shortage.

Effects of Sociodemographic Characteristics on the Stockpiling Behavior
During the COVID-19 pandemic in Serbia, food stockpiling was influenced by several individual and socio-economic variables such as gender, household composition, etc.
Firstly, the results reveal that women stockpiled more food than men. Indeed, only 36.72% of men stocked up food compared to 44% of women. In general, shopping for food and ensuring that enough food is available for the family are women's responsibilities. As indicated by Georgiadou et al. [78], in several countries, during the pandemic, women were less inclined to continue shopping as usual. Additionally, only 37% of the 18-24-year-old participants stocked up on food compared to 47.77% for the 45-54-year-old participants ( Table 4). Secondly, household composition influenced stockpiling behavior. For instance, respondents who were married with children (45.45%) or without children (46.6%) stockpiled more food than those living with their parents (32.53%). Meanwhile, some other sociodemographic features, e.g., income and place of residence, did not affect food stockpiling.
The results confirm that the effects of the COVID-19 epidemic on a consumer's mindset vary according to several sociodemographic characteristics such as gender, age, and household composition. For instance, larger households, especially families with children, tend to stockpile more food than smaller ones. Indeed, the consequences of COVID-19 on the economy, health, well-being, and nutrition varied not only from a household to another but also among individuals [79]. Overall, COVID-19 s effect on consumer behavior has been shaped by many factors, including sociodemographic and household preferences and attitudes [80]. In general, sociodemographic characteristics are essential in predicting consumer purchasing behavior [81] and remain prominent classification variables in marketers' segmentation tactics [82].

Conclusions
In this paper, we investigate the features of stockpiling behavior during the COVID-19 pandemic in Serbia. As observed in several countries, stockpiling behavior in Serbia had been shaped by several factors, including socio-demographics, fear of the virus, etc. Firstly, the results indicate that stockpiling food during the COVID-19 pandemic in Serbia was influenced by various individual and socio-economic variables such as gender, family, etc. Secondly, as expected, stockpiling food was triggered by several factors. For instance, consumers who stockpiled food had a different shopping behavior. They made fewer grocery-shopping visits and spent more on each trip to limit supermarket visits, thereby controlling their perceived risk of exposure to COVID-19. Thirdly, food stockpiling has several consequences. For instance, those who stockpiled food ate out less and ordered less restaurant food and coffee. Furthermore, they cooked more than usual and ate more with family members.

Practical Applications and Limitations
While there have been some promising findings of the effectiveness of the COVID-19 vaccine, the pandemic is far from over, and some countries still face significant disease pressure, but even those who currently control the virus fear more waves. The risk of new infections and waves may result in new lockdowns or new strict measures, and panic buying will likely happen again, leading to further disruption of food systems. For example, cases of panic buying were reported in many countries at the beginning of the second wave in November 2020. More recently, during May 2021, in Taiwan, new COVID-19 restrictions triggered panic buying of food items such as instant noodles [83]. This implies that continued efforts are required to adapt to and mitigate the pandemic's long-term effects. Hoarding of staples has long worried policymakers due to shortages [71]. This and other future research will serve as a foundation for organizational and government preparation for future shocks and pandemic outbreaks. In addition, the paper results indicate that increasing consumer awareness via multi-channel information and communication campaigns, as well as maintaining a consistent supply of agri-food markets, is critical to prevent stockpiling during crises such as pandemics. The study's findings are also useful in developing evidence-based strategies for the post-pandemic recovery period in Serbia and the Balkan area as a whole.
Finally, the major limitation of this study is sample bias, which is a frequent issue in computer-assisted web interviewing (CAWI), which is often employed in surveys [84][85][86][87]. The research participants were unpaid volunteers who were chosen at random (cf. selfselection of the sample). They took the survey because the topic piqued their interest. For example, women and educated people were overrepresented in our sample. Consequently, not every subgroup is represented proportionately. Indeed, web-illiterate individuals, elderly, poor households, and informal workers are excluded from online surveys. With this bias, generalizing the survey findings to the whole Serbian population is challenging. However, due to the COVID-19 epidemic, online surveys may be used to gather data remotely, which is a significant advantage when social distance is required since face-toface interviews are complicated and risky. Funding: This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.  21.
