Pre-hospital emergency personnel as the front line are at risk of COVID-19, and adopting preventive behaviors plays an important role in reducing the rate of disease and mortality. This study aimed to determine the factors affecting preventive behaviors of covid-19 among pre-hospital emergency personnel in Fars province using the protection motivation theory. Various studies have been conducted regarding the efficiency of protection motivation theory in preventive and protection-related behaviors, the results of which indicate the effectiveness of this theory[26, 27]. Therefore, in the present study, this theory was considered as a framework in investigating the mean score of theory constructs, it was found that the protection motivation (the intention to perform protective behavior) had the strongest predicting power, so it can be concluded that the intention of the studied personnel to perform protective behavior was desirable. This can be due to high awareness, continuous use of PERSONAL PROTECTIVE EQUIPMENT including medical masks, eye protectors, gloves, and gowns, based on clinical risk assessment inappropriate size and quality, and adherence to other health behaviors in the workplace. In line with the results of this study, Barati et al. had relatively favorable preventive behaviors of covid-19 among health personnel[28]. However, the results of the study by Nga et al. showed that 30.8% of Hong Kong health personnel had attempted to receive the vaccine at the time of the seasonal influenza outbreak[29]. Protective measures against influenza were reported to be 48% among Irish health personnel[30]. Protective behaviors against diseases and workplace injuries among health care personnel and students such as physicians and nurses were also reported unfavorable in other studies[31-33]. These findings are not consistent with the results of this study. It seems that the difference in the findings of the studies is related to factors such as awareness level, not getting used to masks and gloves, interfering with tasks, especially lack time in pre-hospital missions, emergencies, perceived threat to disease, and training provided in the workplace. According to the results of this study, 44.21% of respondents considered the internet and virtual networks as the most important source of information about covid-19. It seems that social networks were better informed in implementing covid-19 disease prevention training programs than other sources such as personnel, mass media, including television, radio, or magazines, and articles. In the present study, only 4.4% of people reported receiving information about covid-19 from scientific papers, which shows that pre-hospital emergency personnel does not follow up scientific papers well in this study and learn more through cyberspace. In the study of Jaffar et al.[34] and Zare [35], cyberspaces were the most important source and reference for receiving information that is closely related to the results of the present study.
In the present study, the perceived vulnerability construct was relatively high, which was consistent with the results of the study of Ezati Rad et al. [36] which was performed on 2032 people using protection motivation theory to predict covid-19 preventive behaviors and there was a significant positive relationship between preventive behaviors and perceived vulnerability, perceived severity, response efficiency, self-efficacy and protection motivation, and of course, in this study, there was a significant positive relationship between preventive behaviors and perceived vulnerability, perceived severity, response efficiency, self-efficacy and protection motivation. And there was no significant relationship between the cost of perceived response and it was not consistent with our study. The results of this study were also consistent with the results of Najimi et al. [37], Sharifirad et al. [38], and Ezati Rad et al. [36]. Therefore, it can be said that by increasing the sensitivity of personnel to being vulnerable, increasing the fear of repeated contact and exposure to people with symptoms and vectors of the disease and showing the deterioration and seriousness of the disease in protective behavior and on the other hand, by reducing the response costs and internal and external rewards of personnel, it is likely that the intention to perform more protective behaviors in personnel will lead. The study of Cui et al. [39] on avian influenza showed that people understand the severity of avian influenza, but do not see themselves as vulnerable, which was inconsistent with the findings of the present study. It seems that for groups such as pre-hospital emergency departments due to the potential risk of COVID-19, this issue is more serious.
In the present study, self-efficacy and preventive behavior of covid-19 were significant and personnel achieved relative confidence about the ability to perform disease prevention behaviors by understanding that the ways of disease prevention are simple and low cost. In many studies, self-efficacy is the most important prerequisite for behavior change and the strongest predictor of protection motivation [40, 41]. In the study, Ahmadi Jouybari et al. [42], emphasized self-efficacy about preventive behaviors of influenza, which is in line with the results of this study. Also, in the study of Morovvati Sharifabad et al. [26], based on the theory of protection motivation, there was a significant relationship between the constructs of this theory and the intention to perform physical activity in diabetic patients, the constructs of this theory predicted 60% of the variance of physical activity intention, the most important constructs affecting self-efficacy and intention behavior and are consistent with the present study.
In the present study, there is a significant correlation between preventive behaviors and perceived severity and since personnel is aware of the consequences of the disease, they adopt preventive behaviors more carefully. These findings are consistent with a study conducted by Prasetyo et al. [23] on 649 people in Luzon Philippines. In this study, it was found that vulnerability and perceived severity constructs have a significant indirect effect on intention and intention has a significant effect on behavior and also is consistent with a study conducted by Okuhara et al. [43] on 1980 people in Japan, in this study the structures of perceived severity and self-efficacy were strong predictors, but the structures of perceived vulnerability and effectiveness were not predictors. And it also matches the study result of Tazval et al. [40] But it is inconsistent with the study of Zare et al. [44].
In the present study, there was a statistically positive and significant correlation between preventive behaviors and response efficiency, this shows that preventive behaviors are associated with increased self-esteem and increase motivation (intention) in people and are consistent with the results of Malak al Rasheed cross-sectional study conducted on 679 people in Kuwait using PMT, in this study the constructs of perceived severity, perceived vulnerability, response efficiency, and self-efficacy. There was a positive relationship with the intention of preventive behaviors from COVID-19 and in this study; the cost of response construct had a negative relationship with preventive behavior intention which is not consistent with the present study Zare Sakhvidi et al. [45].
In the present study, covid-19 preventive behavior has a significant relationship with protection motivation, which was predictive of protection motivation (intention of behavior) with the results of Bashirian et al. [22] study conducted on 761 hospital personnel in Hamadan based on PMT and its results showed that perceived vulnerability constructs and perceived severity and perceived self-efficacy and response self-efficacy were predictors of protection motivation (intention of behavior) and the intention to predict covid-19 preventive behaviors. Also, it is consistent with the study of Ezati Rad et al. [36], but the results of the study were not consistent with the study. The results of this study showed that there was a significant correlation between all constructs of protection motivation theory and behavior.
In the present study, there was a significant correlation between response cost and behavior, indicating a decrease in behaviors consistent with an increased cost of protective behaviors. Increasing the cost of protection behaviors can be an obstacle against it. Therefore, identifying behavioral barriers and eliminating them may have an impact on increasing adaptive behaviors. In line with the results of this study, 46 colleagues showed that there was a significant correlation between the protection motivation construct and perceived vulnerability, self-efficacy, response efficiency, and reward.
In the present study, behavior showed a significant correlation with all constructs of protection motivation theory. In general, the variables predicted 61.3% of the variance of coronavirus preventive behaviors. The results of this study showed that the theoretical constructs of protection motivation predicted 39% intention and 64% behavior. Also, the results of Alla et al.[46] showed that PMT structures have a considerable ability to define pro-environmental behavior, PMT constructs are "self-efficacy" and "response efficiency" with intrinsic and external rewards predicting environmentally friendly behaviors.
In the study conducted by Williams et al.[47] on 239 people based on PMT, the results showed that none of the PMT constructs had a significant prediction on social distancing behavior that was not consistent with the present study and only the constructs of self-efficacy and self-efficacy of response and fear were significant predictors of intention to address social distancing behavior and in general PMT constructs predicted 21.2% intention. In the study of Morovvati Sharifabad et al.[26] about unsafe behavior in driving, there was a significant correlation between all the constructs of protection motivation theory except fear and perceived vulnerability with unsafe driving (behavior) and unsafe driving intention (motivation) in some other researches, as well as preventive behaviors of cancer at work, response costs were very important [45].
The Study Adunlin et al. [48] showed that PMT is a useful framework for stimulating motivation to observe social distancing during the Coronavirus crisis to stop or slow the spread of COVID-19 in rural areas and need to be used in future research. The emergence of COVID-19 is a rare opportunity to use theoretical frameworks to understand social distancing behavior during this pandemic, to reduce adverse health outcomes among rural and low populations.
One of the limitations of this study was collecting information about the questionnaire through self-report and virtually that people may not have completed the information, although they were given sufficient explanations. Besides, the cross-sectional of this study is another limitation that it is suggested to design and implement interventional studies to accurately determine the effect of protection motivation theory constructs on the protective behavior of laboratory personnel. Therefore, it seems that this theory can be used as a framework for developing educational programs to improve protective behaviors in health centers and hospitals.
