1. Introduction
Fire as one of the most prominent avoidable disasters has been evident in different regions worldwide [
1,
2]. It could be seen that since the 1900s, fire-related disasters have dominantly affected the increase in death [
3]. Thus, it is evident that fire-related disaster is prominent worldwide and mitigation and preparation should be taken into consideration [
4,
5,
6,
7,
8,
9], including the man-made fire disaster. One of the countries that frequently experience man-made fire disasters is Thailand. With Thailand receiving 20 million foreign tourists since 2003, the development of the country has been crucial in all regions and provinces to engage economic development through tourism [
10]. To which, Chonburi has been expanding and developing to attain greater economic development but has poor management [
10]. With the continuous disaster brought about by fire breakouts, the challenge of strategic development, restoration, and safety have become a wide issue in Chonburi Province.
In Thailand, evident fire breakouts have been seen in Chonburi Province, however, this has been underexplored. In March 2017, an industrial estate in Chonburi Province caught fire and the plastic industry made it difficult to mitigate and stop the fire spread [
11]. This was due to the mismanagement of chemicals in the factory, creating the man-made fire. In 2020, a large fire in the district of Chonburi Province occurred and it took 10 fire trucks two hours to mitigate the fire spread [
12]. The reason for this was due to the mishandling and mismanagement of electric circuits. During April and May, two different vehicles just caught fire [
13]. Moreover, on October 2021, houses in Chonburi Province caught fire in the early morning. The same incident happened a week prior [
14]. In September 2021, a fire broke out in a famous nightclub in the same district of Chonburi Province which again took 10 fire trucks around three hours to mitigate the fire spread [
15]. The incident indicated that a lack of breaches in the club caused the man-made fire. It is evident that the area of Chonburi Province is highly likely to suffer from fire disasters, both man-made and natural fires, yet has not been explored regarding the citizen’s mitigation and intention to prepare.
Several studies from different countries have focused on the effects and behavioral aspects of dealing with natural disasters [
4]. Studies from countries such as China considered coping with fire-prone locations [
5]. Du et al. [
5] explored disaster preparedness, disaster coping ability, and risk awareness for safety measures in China. Their study showed how the lack of fire risk reduction planning and measures was evidently not considered by the village, leading to an increase in ill events. In Russia, Porfiriev [
6] showed how methodologies to mitigate natural disasters such as fires and heatwaves in Moscow were not effective against the constant trend in deaths. Moreover, dos Santos [
7] considered the government and public engagement after the fires in Brazil. Their study revealed that the effect of fire hazards would lead to engagement and environmental government action. People’s coordination and collaboration would lead to effective management in risk reduction [
7]. The different studies have highlighted how proper government management to reduce the risk of fires should be highly considered worldwide to mitigate the aftermath.
In addition, Ong et al. [
4] from the Philippines considered mitigation to prepare for “The Big One” earthquake. Their study presented how an understanding of the natural disaster leads to an increase in perceived severity and perceived vulnerability, which would lead to an indirect effect on the intention to prepare. Kurata et al. [
8] determined that geographical perspective and experience would lead to an indirect significant effect on the perceived effectiveness and intention of people to flood disaster response action. Moreover, Gumasing et al. [
9] presented how understanding, perceived severity, and self-efficacy led to the indirect effect on the efficacy of responses to typhoons. These different studies have utilized structural equation modeling (SEM) to highlight the causal relationship of factors affecting the behavior in regard to preparation and mitigation. It was evident from the studies how the effects of knowledge and experience would lead to people’s intentions. The key highlight would be the consideration of the integration and extension of the protection motivation theory (PMT) and theory of planned behavior (TPB) to holistically measure people’s intentions and response when it comes to natural disasters.
Other studies of natural disasters in Thailand have been considered. Tanwattana [
16] systematized community-based disaster management in the upstream area of Thailand. However, their study focused on urban floods and only those in prone communities. Pathnak and Ahmad [
17] considered recovery capacity in Thailand. Although significant findings such as coping mechanisms and the impact of flood disasters were evident, their study only focused on flood-related disasters. In addition, Okazumi and Nakasu [
18] considered actual situations but focused on earthquakes and tsunamis that happened in 2011. Lastly, Fakhruddin and Chivakidakarn [
19] considered early warning and disaster management for socio-economic change on influence towards disaster risk management. They highlighted how the government’s different actions and plans would be one of the best solutions to mitigate natural disasters happening in the country. Despite several studies being available, no studies regarding man-made fire disasters focusing on Chonburi Province were found. In addition, the need to explore the intention to prepare for fire hazards and disasters is evidently needed.
Measuring the intention of people towards disasters such as man-made fire disasters could be done by utilizing and extending the PMT and TPB model [
4,
8,
9]. PMT is a framework used to measure coping and threat appraisal, preceded by perception, knowledge, or understanding of a certain natural disaster. McCaughey et al. [
20] presented how the intention to perform an act in relation to health-related behavior could be measured with PMT. Several factors may be considered which represent threats and coping appraisals such as perceived vulnerability, perceived severity, and response cost [
21]. Covey et al. [
22] discussed how individual differences should be considered upon investigating protective measures and individual harm. This indicates that PMT alone cannot holistically measure both personal behavior and health-related behaviors. Justifiably, Ong et al. [
4] explored the integrated PMT and TPB and indicated how it can measure the actions and the intention of an individual to mitigate natural disasters.
TPB considers main variables such as subjective norm, perceived behavioral control, and attitude towards the behavior that affects an individual’s intention [
8]. Kurata et al. [
8] highlighted how PMT alone has been widely considered in disaster-related studies but commonly has several limitations with regard to measurements. Gumasing et al. [
9] suggested extending several factors for PMT such as behavioral variables to measure the response of individuals toward natural disasters. In this study, adapted and extended integration of PMT and TPB was utilized to measure the intention to prepare for the mitigation of fire in Chonburi Province, Thailand.
The current research utilized structural equation modeling (SEM) for the measurement of the causal relationship for intention to prepare for mitigation of disasters [
23]. Gumasing et al. [
9] utilized SEM to measure response to a typhoon natural disaster, similar to Kurata et al. [
8]. Ong et al. [
4] measured the intention to prepare for the mitigation of the “Big One” earthquake in the Philippines. Their study showed how SEM is a reliable multivariate tool to determine significant latent variables to measure people’s behavior and intention. However, several limitations were noted. Following the findings by Woody [
23], he indicated how mediating effects of latent variables in a framework may lead to low or insignificant relationships from the present causal relationship. Fan et al. [
24] explored the structure of SEM and indicated how indirect effects far from the dependent variable would cause a low to no significant relationship. Thus, to resolve the limitation present in SEM, Duarte and Pinho [
25] suggested combining SEM with another tool to help resolve the disadvantages. This study, therefore, considered an artificial neural network (ANN) to help determine key constructs that affect the intention to prepare for mitigation of fire disasters.
ANN is a machine-learning algorithm that adopted the response the human body makes through the transfer of signals from neurons to the brain [
26]. Beran and Violato [
27] explained how an ANN was utilized to determine the health-related behaviors of different individuals. To which, this study optimized the parameters set for running the ANN model. The different activation function of the hidden and output layer was considered, as well as the optimizer and the number of nodes present.
The aim of this study was to assess and predict factors affecting the intention to prepare for the mitigation of man-made fire disasters. With the evident fire-related disasters in the Chonburi Province region in Thailand, several factors such as geographic perspective, fire perspective, government response, perceived severity, response cost, perceived vulnerability, perceived behavioral control, subjective norm, and attitude were evaluated simultaneously to measure the intention to prepare. Through the integration of PMT and TPB, a hybrid of structural equation modeling (SEM) and artificial neural network (ANN) was utilized due to the limitation of SEM solely [
26]. Thus, the results of this study could be applied and extended to other disaster-related studies to measure the intention to prepare for mitigation.
This study is considered the first complete study that analyzed behavioral intention to prepare for mitigation of fire disaster in the Chonburi Province region in Thailand. In addition, the findings may be utilized by the government to create mitigation plans applicable in Thailand, and even across different countries. Lastly, the theoretical framework and methodology applied may be considered to evaluate the behavior related to man-made fire disasters worldwide.
2. Conceptual Framework
The conceptual framework utilized in this study is presented in
Figure 1. Under PMT, variables such as fire perspective (FE), perceived severity (PS), response cost (RC), and perceived vulnerability (PV) were considered. Under TPB, perceived behavioral control (PB), social norm (SN), and attitude towards behavior (AT) were considered. In addition, an extension adopted from Kurata et al. [
8] was considered with variables such as geographic perspective (GP) and government response (GR) to measure intention to prepare (IP). To which, 17 hypotheses were created and tested with SEM and ANN for the distinction of significant factors affecting the intention to prepare for the mitigation of man-made fire disasters.
Experience from prior disasters indicates historical events that an individual was in contact with. The study by McCaughey et al. [
20] presented how knowledge regarding a disaster event would lead to a significant factor affecting people’s intention to evacuate an area. In addition, Ong et al. [
28] presented how the individual understanding of risk would be a key factor affecting people’s behavior. Their study showed how the benefits of health-related activities would drive people toward acceptance. The different studies have presented how the perception of people towards a disaster would greatly affect their perception of vulnerability, severity, and even response cost. The experience of being greatly affected by a disaster would lead to heightened PS, PV, and RC [
8]. This is supported by the study by Gumasing et al. [
9], wherein response efficacy is preceded by people’s perception of a disaster, leading to perceived risk (associated with PV) and susceptibility (associated with PS). This would advance the individual’s self-efficacy and also affect RC. Thus, the following were hypothesized:
H1: FE has a significant direct effect on PS.
H2: FE has a significant direct effect on RC.
H3: FE has a significant direct effect on PV.
The GR towards the present disaster affects how people would be led to act. If the government was able to present valuable information and knowledge towards a response during a calamity, individuals would have lower costs in the aftermath of the disaster [
8]. To which, the experience people have with the mitigation plans would help develop instincts to build on regarding preparation for mitigation [
28,
29]. However, this study considered GR as a latent variable that does not directly affect PS and PV. This is because individual perceptions are being measured instead of a relative outside influence (i.e., the government). Thus, to reduce the bias of significant effect, only those that have individual perception and motives (e.g., GP and FE) were considered to directly affect PS and PV. On another note, resilience among individuals increases when a disaster would negate the tangible presence in a household [
30,
31]. This also relates to people’s geographic location. GP affects individuals’ PV and PS [
8]. Mashi et al. [
32] indicated how the perception of severity and vulnerability would increase their feelings of susceptibility when located in areas close to disasters. It could therefore be highlighted that GP affects PV and PS when the location is prone to disaster-related scenarios. Thus, it was hypothesized that:
H4: GR has a significant direct effect on RC.
H5: GP has a significant direct effect on PS.
H6: GP has a significant direct effect on PV.
The response of people towards a disaster may be accounted for. In the case of the study by Gumasing et al. [
9], RC affects the behavioral aspect of a person. Mechler [
33] indicated how RC should be considered upon creating a mitigation plan for disaster-related activities. To which, the behavioral aspects of people should be considered to attain higher response action. Covey et al. [
22] expounded on highlighting individual differences, thus RC should be considered as a factor affecting different behaviors such as PB, SN, and AT. In addition, it was seen from the studies by Ong et al. [
4] and Ong et al. [
28] how these three variables under TPB highlight the action of an individual. Thus, the following were hypothesized:
H7: RC has a significant direct effect on PB.
H8: RC has a significant direct effect on SN.
H9: RC has a significant direct effect on AT.
PS and PV are key indicators under PMT which measures the motivation of an individual to protect themselves from disaster-related events. Westcott et al. [
34] and Tang and Feng [
35] explained how threat and coping appraisal of people affects individual behavior. To which, PS was indicated to affect PB, SN, and AT. The aim of people is to reduce the risk that may affect them or the people around them. Ong et al. [
4] presented how PS and PV directly affect PB, SN, and AT—the integration section of PMT and TPB. It was highlighted that when PS is increased, these three factors would be affected in a directly proportional way. These relationships are similar to the studies presented by Prasetyo et al. [
36], Ong et al. [
28], and Kurata et al. [
8]. Thus, it was hypothesized that:
H10: PS has a significant direct effect on PB.
H11: PS has a significant direct effect on SN.
H12: PS has a significant direct effect on AT.
H13: PV has a significant direct effect on PB.
H14: PV has a significant direct effect on AT.
Under TPB, three latent variables such as PB, SN, and AT were used. Ham et al. [
37] showed how PB affects IP due to the ease or difficulty when behaviors are executed. Kahlor et al. [
38] showed how individuals decide on positive self-control compared to the negative connotation of losing self-control. Moreover, Kahlor et al. [
38] also showed that SN is one of the factors under information-seeking behavior in TPB. It is indicated in their study that SN precedes IP due to past experiences of people around an individual. To which, Lin et al. [
39] showed how the environment the individual is in impacts evacuation and preparedness. AT towards risk perception in disaster-related events is positively connected to an individual’s preventive measures [
40]. In addition, Budhatoki et al. [
41] showed how AT can be connected to the negative IP when preparedness before the event happens. Furthermore, different studies have presented how the three TPB latent variables significantly affect IP in disaster-related events [
8,
28,
42]. Thus, the following were hypothesized:
H15: PB has a significant direct effect on IP.
H16: SN has a significant direct effect on IP.
H17: AT has a significant direct effect on IP.
5. Discussion
Evident fire disaster has been seen to be present in the Chonburi Province in Thailand. The need to assess factors affecting the intention to prepare for a fire disaster should be explored. This study utilized the SEM-ANN hybrid to test the hypotheses created and predict factors affecting intention to prepare (IP) for fire disaster with factors under PMT and TPB. Several factors such as fire perspective (FE), perceived severity (PS), response cost (RC), perceived vulnerability (PV), perceived behavioral control (PB), social norm (SN), attitude towards behavior (AT), geographic perspective (GP), and government response (GR) were assessed simultaneously.
From the results, GP was seen to be the most significant factor (100%). The SEM results presented a direct effect on PS (β: 0.326;
p = 0.009) and an indirect effect on IP (β: 0.065;
p = 0.002). The respondents think that the government should classify and monitor fire risks, manage and monitor fuel consumption, and consider wildlife that may cause fire disasters. GP is an important factor affecting IP because the location of a person affects how severe the impact of a disaster would be [
8]. The more susceptible the location of an individual is to a disaster, the more likely they will prepare for it [
9]. Accordingly, Bronfman et al. [
55] highlighted how people in Chile would consider the more negative effects of disaster when dealing with IP. Similar to the study of Shi et al. [
56], people in China would consider positive and high IP when presented with high negative effect of disasters.
Second, SN was seen to directly affect IP. The SEM result suggested that SN has a highly significant direct effect on IP (β: 0.602;
p = 0.009) and is the second-highest important factor (92.3%). The influence of industries was indicated to have an effect on fire disaster, people around the individual were said to be affected by fire disaster, and the workplace and lifestyle of an individual were seen to be indicators of this factor. Kusumastuti et al. [
57] confirm the claim that SN is a significant factor affecting IP. People would respond to a disaster when people that are important to them would be affected as well. This leads to a motivation to increase IP [
38] upon dealing with how people are living day to day. Similar results were also found for people living in the Philippines [
4,
8].
Third, FE is a significant factor affecting IP (91.8%). The indicators show how the workplace and household should prepare for fire disaster based on experience, create evacuation plans, have insurance for fire disaster, and consider the installation of smoke and fire alarms. This has led to a direct significant effect on RC (β: 0.585;
p = 0.023) and PB (β: 0.481;
p = 0.006), with an indirect effect on IP (β: 0.363;
p = 0.018). Shen et al. [
58] showed how different experiences and behavior of people would lead to an act not similar to other individuals. Similarly, Gumasing et al. [
9] showed how the knowledge and understanding of people would increase their perception of the severity of a disaster, leading to an increase in their IP. Kurata et al. [
8] also presented similar findings when people’s experiences would increase their alertness and preparation for the mitigation of disasters.
Fourth, PS was seen to be an important factor affecting IP (87.6%). The indicators considered constructs such as the serious hazard of fires, loss of property, and injuries; people perceive fire as more dangerous than other disasters, and should have sanction among people that breach fire regulations. This has led to direct effects on people’s behaviors such as SN (β: 0.431;
p = 0.013) and AT (β: 0.257;
p = 0.021) with an indirect effect on IP (β: 0.198;
p = 0.0019). This is supported by the results of the study by Bollettino et al. [
59]. The increased awareness and knowledge of a disaster would also increase people’s IP. Taking into consideration available resources and information would lead to knowing PS, which will increase the motivation for IP [
60]. It could be stated that PS is directly proportional to IP when dealing with disasters [
4].
Fifth, AT directly and significantly affected IP (β: 0.296;
p = 0.042). The indicators presented the significant results of how people perceive fire as a danger to the community, wildlife, people and properties, and that people in the community are not aware of the fire. This led to a high score of importance for AT (85.2%). Ong et al. [
4] showed the increase in IP when people perceive the heightened level of danger from disasters. The way other people would feel and act would affect the attitude of an individual to act the same way. In this case, if the perceived danger is within the surroundings, then people would have a positive AT affecting IP. As support, Song and Shi [
61] explained how AT is affected by societal pressure and the evident effect of fire on their surroundings. AT was indicated to be an important factor greatly affecting an individual’s IP [
62].
Six, RC had an importance score of 83.4%, which directly affects IP. To which, a direct effect on the TPB latent variables of PB (β: 0.343;
p = 0.009), SN (β: 0.512;
p = 0.013), and AT (β: 0.629;
p = 0.005) were seen. It was shown that people believe that filing sanctions, claiming fire insurance loss fees, and paying remediation for fire victims should be in place. The increase in stress due to RC has been evident across countries [
7,
63]. The increase in the number of disasters in Oceania also increased RC [
58]. In addition, the increase of disasters in the Philippines increased RC as well [
7,
9]. Gumasing et al. [
9] highlighted that RC would lead to a positive significant effect on different behaviors of individuals when investment in risk reduction is not applied. These findings justified the results presented.
Seventh, PB was shown as the least important but significant factor affecting IP (β: 0.180;
p = 0.043). It was indicated that people know where fire alarms and extinguishers are, know emergency contacts, can perform first aid, know what to do when there is fire, believe they can mitigate fire disaster when it happens, and can evacuate easily when there is fire. This explains why PB has a low score of importance (76.9%) due to people believing they can manage fire if it occurs. Mondino et al. [
64] explained how people with prior experience and knowledge of a certain disaster know what to do when it occurs again. Individuals with details and particulars of a disaster such as fire, result in their willingness and positive behavior to prepare and mitigate it happening negatively [
65,
66].
Eighth, GR proved to be an important and significant factor affecting IP (75.7%), with a direct significant effect on RC (β: 0.519;
p = 0.005). Indicators presented constructs such as the government having to pay remediation, establish fire foundations, practice evacuation plans, manage policies, and establish reforestation campaigns. Following the study of Kurata et al. [
8], GR was shown to have a low significance level as well. Their study highlighted how retroactive governance would lead to an increase in people’s behavior to prepare and mitigate disasters. Moreover, Gumasing et al. [
9] and Ong et al. [
4] explained how the impact of the government on creating policies and plans would increase the factor affecting citizens’ intentions to prepare for the mitigation of disasters such as fires.
Lastly, PV affected IP significantly (indirect β: 0.020;
p = 0.014). People think they are vulnerable to fire, their location, family, and friends were also indicated as vulnerable. Thus, a direct significant effect on PB (β: 0.257;
p = 0.004) was seen. Seeing how people believe they can control their actions and know what to do when a disaster occurs led to the lowest score of importance for this factor (49.3%). Similar to the study by Kurata et al. [
8], PV was considered to have a low-significance effect on people’s behavior. However, Kusumastuti et al. [
57] showed that despite the low significance, people will still proactively take action to reduce the negative impact of a disaster. Moreover, Weichselgartner and Pigeon [
67] showed how knowledge and experience of a disaster would lead to low PV, but would result in gaining more information to understand disaster risks and mitigation. Thus, supporting the findings of this study.
Interestingly, it was seen from the IP indicators that people would not prefer to use old electronic appliances to prevent fires, mitigated by placing chemical substances in designated areas, maintain electronic and circuit systems, keep oils, fuels, and children away from electronics, and turn off power sources when not in use. From the findings, it could therefore be deduced that people are aware of their location being prone to fire disasters, people around and important to them are vulnerable to the disaster, and experiences due to the constant number of fires happening in the area would lead to urgency to prepare for mitigation of the fire disaster.
5.1. Theoretical and Practical Contribution
The evident results showed how the extended integrated framework of PMT and TPB could be utilized as a framework to measure people’s intention to prepare for the mitigation of disasters. The contribution of extending factors such as government response and geographic location were important since the consideration of specific areas of study was seen to be prone to fire disaster. Thus, this study posits that when dealing with specific disaster-prone areas, these factors may be included. Moreover, the implementation of the SEM and ANN hybrid led to more substantial findings for factors influencing human behavior. It could therefore be suggested to include machine learning tools with SEM to help resolve the disadvantage and flaws of the single tool alone.
Based on the findings of this study, the government would play a significant role in reducing response cost, perceived severity, and perceived vulnerability among citizens. Thus, the findings of this study could be utilized by the government sector to create mitigation plans to reduce the severity of disasters such as fire. Moreover, the government may capitalize on the findings of this study to promote the intention of people to reduce, mitigate, and prepare for any disasters that may occur. The findings of this study could also be applied and extended by other researchers dealing with disasters in different countries. Lastly, the framework and methodology of this study may be utilized for studies dealing with human behavior worldwide.
5.2. Limitations and Future Research
Despite the strong and significant findings of this study, several limitations could still be considered. First, though sufficient, this study was only able to consider a few respondents to be generalized. Second, only an online self-administered cross-sectional survey was utilized in this study. It is suggested to consider more respondents, distributed among the more diverse age groups, and even consider interviews. This way, more factors and findings may substantiate lacking information that may not be found in the paper. Third, only the SEM-ANN hybrid was utilized to confirm the findings. It is suggested that future researchers may create clustering methods such as particle swarm optimization and fuzzy clustering to determine similar indicators affecting human behavior such as intention to prepare. Lastly, it is also suggested to consider different employment statuses and marital status to highlight significant differences among factors affecting the intention to prepare when it comes to ownership of property and dependence.
6. Conclusions
The evident negative effect of man-made fire as a disaster has been seen worldwide. This has led to a constant or increased amount of damage and even death in different countries. One of the regions that suffer consistent fire disaster is Chonburi Province in Thailand. However, despite the presence of a number of fire disasters in Thailand [
68,
69,
70,
71,
72,
73], this has been considered underexplored. This study aimed to predict factors affecting the behavioral intention to prepare for the mitigation of man-made fire disasters in Chonburi Province, Thailand.
Several factors under the integrated and extended protection motivation theory and theory of planned behavior were considered in this study. Factors such as geographic perspective, fire perspective, government response, perceived severity, response cost, perceived vulnerability, perceived behavioral control, subjective norm, and attitude were evaluated simultaneously to measure intention to prepare for fire disaster in Chonburi Province, Thailand. A structural equation modeling and artificial neural network hybrid approach were utilized in this study to evaluate 20,496 datasets collected from 366 respondents. Through an online self-administered cross-sectional survey, the response was collected through convenience sampling to represent the generalized results presented.
The results indicated how geographic location, subjective norm, fire experience, and perceived severity were significantly evident and important factors affecting the intention to prepare. It was seen that people with knowledge would consider the level of severity of a disaster based on experience. In addition, the effect on the community and people that are important to an individual would heighten their behavior and attitude for intention to prepare for mitigation of fire disaster. Moreover, the geographic location was seen to be the most important factor contributing to intention to prepare. Since the Chonburi Province has been repeatedly struck with fire disasters, it explains how the geographic location is considered the most important factor affecting intention. In order to increase the level of intention among people, it was deduced that the government should implement mitigation plans, create protocols and policies, and even give sanctions to promote and mitigate fire disasters in the area. To which, government response and response cost were also considered significant factors.
The findings and results of this study may contribute to the government sector in creating plans to protect citizens in the Chonburi Province region in Thailand. In addition, the results presented may be considered by other researchers to strengthen findings of human behavior in relation to natural disaster preparedness. The framework and methodology considered in this study may be applied and extended to measure human behavior studies, not only in natural disasters. Moreover, the application of the SEM-ANN hybrid may be considered by health-related and behavioral researchers worldwide.
