COVID-19 is an imminent public health concern. To manage the spread and social impact of this pandemic, it is crucial that citizens be engaged in preventative behaviors such as social distancing, use of personal protective equipment, personal hygiene, and limited presence in the community as much as possible. Understanding the cause of differences in these behaviors is imperative, as such, the present study aimed to investigate the public’s preventive behavioral responses and their barriers and drivers during the COVID-19 outbreak.
The findings indicated that socio - demographic and economic characteristics differently affect some aspects of protective behaviors (PPE, SOD, GHH, and ROA). For example, although women have greater intention to use protective equipment than men, they exhibit equal intention to adhere to social distancing. Additionally, the intention to adopt person-based measures was less affected by demographic and economic characteristics, compared to community-based measures. Previous studies have shown that exhibiting preventive behaviors over the outbreak of infectious diseases varies depending on the transparency of measures (exactly what they should do) and their practicality (if it is possible for the individual to adopt them) (
24,
25). Based on a study on preventive behaviors in the initial phases of the influenza A virus subtype H1N1 outspread in 2009, a larger proportion of participants tended to wash their hands more frequently or avoid those with cold symptoms (55 - 67%) compared to the individuals who were willing to avoid going to crowded places, contact with specific races, or cancel their traveling programs (13 - 27%) (
24). According to an examination of preventive behaviors over the SARS outbreak in 2003, the practice rates of hygienic behaviors, including washing hands, using face masks, and disinfecting, were reported as high as approximately 65 - 87%; however, the rates of avoiding specific places including markets or hospitals along with the use of public transport were as low as 24 - 75% (
25).
In line with previous research, the findings of this study showed that the main drivers for protective behaviors are related to risk perception, social responsibility, and sensitivity to ensure personal and family health. Kim and Kim (2018) showed that individuals perceiving a lower risk of contracting MERS had totally undesirable attitudes regarding quarantine (
2). Choi and Kim (2016) confirmed that attitude and perceived risk were the main variables strengthening preventive behaviors among nursing students during the MERS outbreak (
26). Moreover, Brug et al. (2004) found a correlation between the perception of risk and precautionary actions to avoid SARS (
27). Yoo et al. (2016) recommended public health authorities and communication professionals to employ social network sites (SNS) for the effective management of social and economic challenges brought by the outspread of infectious diseases through highlighting the impact of SNS communications on public perceptions regarding risk as well as preventive behaviors (
28). Accordingly, with considerable stress on the severity of COVID-19 along with social responsibility to frame messages about the importance of preventative behaviors during the pandemic, citizens’ compliance with health officials and government recommendations may be improved (
29).
The main barriers to the protective behaviors of social distancing and good hand hygiene are cultural and informational barriers. Therefore, in accordance with a systematic review by Jefferson et al. (2009), efforts should be mainly focused on the reduction of transmission from young children by efficient educational programs at school regarding hygiene. Moreover, social investments need to concentrate on more convenient face masks with more favorable designs and barrier apparatus to make them more compatible with their application (
30). Dyson et al. (2010) explained that identifying further barriers can be helpful in addressing non-compliance with hand hygiene (
31).
In the case of using protective equipment, the main problem was accessibility, and job was a major obstacle to follow this advice in the case of restricting economic activities. The findings revealed that despite problems with access to masks and disinfectants during the study period, the use of preventive equipment had no significant relationship with the economic situation. Teasdale et al. (2014), in a systematic review, highlighted socio-economic barriers to adoption of social distancing behaviors. This is consistent with our study and showed that individuals engage in the active evaluation of non-pharmaceutical interventions considering their perceived necessity, efficiency, admissibility, and practicality. To promote uptake, addressing primary barriers seems essential, among which beliefs regarding the transmission of the infection, rejecting individual infection risks, concerns regarding the possible costs, and stigma related to specific interventions can be mentioned (
32).
Furthermore, Sun et al. (2013) explained the determining factors of health literacy and its relationships with health behaviors. According to their study, these two variables showed positive mutual associations (
33). The results of our study also showed that most of the preventive behaviors are exhibited by the educated.
In line with our study, Jang et al. (2019) asserted that awareness regarding the efficiency of preventive behaviors enhances the adoption of these behaviors (
13). On the other hand, Lunn et al (2020), in their recent study, specified that education and information, while important, were not sufficient to change behaviors (
34). Furthermore, the level of education not only promotes favorable perceptions of preventive behaviors, but also promotes the quality of preventive measures (
13).
Lunn et al. (2020) also displayed that isolation duration is important. In this regard, clarity and certainty of the timelines were both important (
34). The issue seems to have indirectly affected our study, as well. This is because the study was conducted in the first months of the epidemic, and the participants were likely to answer questions with the assumption that the outbreak would be controlled soon during the next few months.
In line with our research, Bish and Michie (2010) referred to demographic behavioral differences, including being at an older age and female gender, while having higher education was related to more chances of behavioral adoption (
16). Based on the available evidence, higher levels of perceived susceptibility and perceived severity of the disease, along with higher belief in the efficiency of the proposed behaviors for protection against the disease can be considered significant predicting factors of behaviors (
16,
22).
In line with our findings, Webster et al. (2020) claimed that the most prevalent factors influencing individuals’ commitment to quarantine included their knowledge on the outspread of infectious diseases along with quarantine protocols, social norms, perceived advantages of quarantine, perceived risk of diseases, and practical aspects of applying quarantine (
35). It has been also indicated that such factors affect commitment to other protective health behaviors exhibited for infectious diseases, including washing hands, use of face masks, and avoidance of crowds, and vaccination (
35). Previous studies have detected various factors having significant effects on behavioral changes toward healthy behaviors in infectious diseases, which include health literacy, education, prior knowledge, age, gender, economic status, health status, attitudes toward the severity of diseases, etc. (

5.1. Limitations and Suggestions for Future Research
Several limitations of the current work should be mentioned before generalizing the findings so that they would be dealt with through further studies. First, the uncertainty of the epidemic duration can change the findings, and more studies need to be conducted over time to determine how people behave.
Second, this analysis used cross-sectional survey data; therefore, the correlations observed among the variables in the study are not sufficient to establish causal claims. Nevertheless, the within-regression model was grounded in strong theoretical reasoning, and the interpretation of the findings is in line with previous research. Future research adopting a longitudinal or panel approach is recommended to make stronger causal claims or investigate the changes in preventive/protective behaviors in accordance with changes in the COVID-19 epidemic. Third, the study examined the single issue of COVID-19 in Iran, which may limit the generalizability of the findings to other issues or other countries. Future studies may benefit from examining a broader range of risk and health issues or this topic in various countries to obtain a deeper perception of the barriers and drivers of preventive measures during the COVID-19 outbreak. Fourth, another point to consider is the study timing, which coincided with the New Year’s holidays in our country. Under such a condition, many economic and social activities were automatically closed, except for travel and sightseeing businesses, by implementing government policies. Accordingly, it is still unclear whether individuals will still keep their social distance after this period. Finally, the evaluation of preventive behaviors’ efficiency was not possible in the present work since only questions concentrating on if participants performed these behaviors or not and the related drivers and barriers had been considered.
5.2. Conclusion
The study findings have remarkable implications for policymakers to have an effective plan for risk and health communication during this ongoing outbreak and future national risk events affecting public health. Therefore, to manage the social response to the COVID-19 pandemic, the drivers should be used effectively, and the obstacles should be controlled as much as possible. Also, each group of the audience should be specifically alerted, and targeting risk communications are recommended. Collaborative prevention measures require appropriate public considerations according to efficient risk communication.
