  Abstract 


Aims: Increasing staff awareness in the workplace can reduce the damage caused by natural disasters and emergencies. The aim of this study was developing a valid and reliable tool to measure the level of the public awareness on emergency response and assess this in Iran dairy industry. Materials and Methods: The awareness level was assessed by constructing a researcher-made questionnaire. A 62-item questionnaire was provided. After face validation, content validity was assessed using content validity ratio and content validity index method and finally 56 final questions were prepared. The construct validity of the questionnaire was assessed using Kaiser-Meyer-Olkin (KMO) index test and Bartlett's sphericity test. To assess the reliability of the questionnaire, it was investigated on 425 Iran Dairy industry staff using Richardson Kouder 20 test. Principal factors were extracted using exploratory factor analysis by analysis of variance method by SPSS version 22. Results: The KMO index was 0.331, so factor analysis was not possible. Bartlett's sphericity test also showed P < 0.001, and confirmation was successful. The reliability coefficient of the questionnaire by using Richardson's Kouder 20 test was 0.711. The public awareness on emergency response in Iran dairy industry staff was evaluated as moderate to optimal. Conclusion: The public awareness on emergency response in the workplace questionnaire which has been designed has appropriate validity and reliability and can be used to assess public awareness on emergency response in the workplace.

  Introduction Top


Emergency is a situation created by nature (without human intervention) or by humans intentionally or inadvertently causing enormous human, material, and environmental damage.[1] Emergencies are sometimes referred to as crises, all natural events such as tornadoes, tsunamis, hurricanes, snowstorms, volcanic activity, explosions, fires, and floods called external assistance needs.[2] Crises are divided into three categories: natural, technological, and terrorism.[3] Emergencies are identified as an unpredictable situation, threatening companies, workers and society and disrupting or stopping operations.[4] Every year, 200 million people get involved in unexpected events and hundreds of thousands die. The number of natural disasters has doubled in recent years.[5] Disaster-prone countries suffer an average of about 3% of their gross domestic product annually, which indicates the importance of awareness and planning in dealing with these disasters.[6] Climate change, human manipulation of nature, and the rapid growth of technology have increased the vulnerability of people and the occurrence of events. Studies show that Iran is a disaster-prone country and one of the most susceptible countries in the world for disasters. In general, Iran is one of the 10 disaster-prone countries and 90% of its population is exposed to flood and earthquake hazards.[7] Apart from being known as the most deadly earthquake in the world,[8] other disasters and accidents also account for a significant proportion of deaths. In other words, Iran is the fourth country in Asia after India, China, and Bangladesh, and the sixth largest in the world in casualties, indicating the importance and awareness of how to deal with emergencies.[7] In addition to natural disasters accidents such as fires and fires are known as disasters caused by human activity. Fire and explosion accidents in small and large industries cause many financial, environmental and environmental damages to different communities each year.[9] Even today, radiation accidents are significant disasters, with the dangers of ever fearing the possibility of a terrorist attack on power plants and reactors and unintentional incidents within power plants, including explosions and leaks of radioactive materials and radiation accidents in parts. It is medical therapy.[10] Since emergencies are rarely occurring and the timing of their occurrence is unclear, it is therefore necessary to coordinate with them beforehand so identifying potentials and maintaining preparedness to respond to emergencies can to minimize the damage caused by such events.[4] Although most disasters are out of human control, the damages and damages caused by it can be substantially controlled.[11] Raising awareness among officials and the public can be helpful and prevent the spread of disabilities and communicable diseases.[12] There are always two main behaviors when responding to emergencies: law-based behavior and knowledge-based behavior.[13] Knowledge-based behavior is the awareness[14] that is background of preparedness. Preparedness is a collection of natural disaster management capabilities. Preparedness includes a collection of activities and proceedings before the event of natural disasters to foretaste, warning, release people and finance from threats, and effective response to critical situations.[15] Extensive research has so far been undertaken to assess the awareness and preparedness of organizations and communities for disasters and disasters. The tools used in these studies have each been used to measure disaster awareness or preparedness.

In a research by Masoud et al., the preparedness of Tabriz hospitals for emergencies was evaluated.[6] Hospital readiness was assessed by a checklist that examined only the level of logistical readiness and management and did not include the readiness of individuals. In addition, only unexpected events were investigated. In another research from Vosoughi Nayeri et al., they examined the knowledge of health students of Tehran University of Medical Sciences about emergencies.[11] Researchers developed a 20-item questionnaire to measure people's awareness of health issues and emergencies. In another research from Ghafari et al., it examined the preparedness of hospitals affiliated to the University of Social Welfare and Rehabilitation Sciences for unexpected events.[16] Based on the researcher-made questionnaire, hospital readiness for unexpected events was assessed. In another research from Hayati et al., they examined the preparedness of Bandar Abbas hospitals for natural disasters.[17] Using a researcher-made checklist of 220 questions with yes and no answers, hospital readiness was simply measured. In another research from Kihila, in which fire preparedness and situational analysis were examined in Tanzanian higher education institutions,[18] this research was conducted using a researcher-made questionnaire that just measure fire preparedness. A research by the Banister Institute, which examined household preparedness for emergencies and disasters, used a 20-item questionnaire.[19] In another study by Glauberman and Qureshi that examined citizen readiness of high-rise buildings,[20] the research used a researcher-made questionnaire to measure fire accident preparedness.

According to the researches, so far, a questionnaire with validity and reliability has not been developed to measure the level of awareness of people in the face of emergencies and disasters in the workplace. Therefore, this study will be conducted in order to developing and psychometrically measure the public awareness about coping with emergencies in the workplace.


  Materials and Methods Top


This research is a descriptive study aimed at development and psychometric of questionnaire measuring the public awareness emergencies response in the workplace. Studied population in this research to assess face validity and content validity of the questionnaire, was 15 health, safety, environment (HSE) experts, occupational health, environmental health, safety, disaster and emergency health management, and disaster management with minimum master's degree. Studied population to evaluate the reliability of the questionnaire was 425 employees of one of the subsidiaries of Iran dairy industries.

For carrying out the present research, the following steps were taken:

  1. Studying internal and external books and articles and reviewing effective information on emergency response
  2. Providing an initial framework using the results of the studies
  3. Identify effective factors on awareness of emergency response
  4. Prepare a questionnaire bank
  5. Check the face validity and content validity of the initial questionnaire
  6. Check the reliability of the final questionnaire.


The questions were categorized into three categories including preemergency, during emergency, and postemergency. This classification was according to [Table 1].

The questions were mult choice question (four selection format) with one correct answer.

The initial questionnaire was sent to two HSE experts to apply their opinions by studying the questionnaire. After receiving the comments of the experts, modified questions for content validity were presented.

The content validity of the questionnaire was assessed using the opinions of 15 experts through the method of Lawshe. In this method, criteria of necessity are calculated using relative content validity ratio (CVR) and criteria of proportionality using content validity index (CVI).[21]

[Table 2] shows Lawshe's decision to calculate the CVR.

In the present study, according to the experts, questions with CVR score higher than 0.49 were accepted and questions with CVR score less than 0.49 were removed in questions bank.(Based on the Lawshe's table). Questions with a CVI score higher than 0.7 were accepted and <0.7 were reviewed. After confirming the content validity, the original questionnaire was distributed among the studied sample (425 persons), and after completing the questionnaires, the data were analyzed by SPSS ver 16 (SPSS Co, Chicago, ILL, USA).

After collecting data, to investigate the construct validity of questionnaire, because the answers to the questions were scored true and false, the Kouder–Richardson 20 (Kr20) internal consistency method was selected and used.[22] In this method, the test was performed only once, but all test factors were analyzed. If the index is more than 0.7, the questionnaire is valid. Kr20 equation is:



Note: n is number of questions – p is ratio of correct answers – q is ratio of wrong answers – S2 is variance of total scores.

Construct reliability was assessed using Kaiser–Meyer–Olkin (KMO) test and Bartlett's sphericity test. These are part of factor analysis tests.[23]

Descriptive analysis was performed on the scores of awareness of emergency response and others variables based on analysis of variance (ANOVA).

After completing the initial bank of questions containing 62 questions, the face validity was assessed. Content validity was assessed after face validation. Finally, the final number of questions was reduced from 62 questions to 56 questions and questionnaire was distributed among the sample population. [Table 3] shows the CVI of the questionnaire for preemergency phase, [Table 4] shows the CVI of the questionnaire for during emergency phase, and [Table 5] shows the CVI the questionnaire for postemergency phase of this research.

According to the Kr20, the validity coefficient of the questionnaire was 0.711.



According to KMO test, factor analyzing was not possible (KMO = 0.331), but Bartlett's of spheriity test showed factor analyzing is possible (P < 0.001).

The following quantitative results were obtained from this research.

83.5% of the study population were men and 16.5% women. The highest age group was 30–40 years old (41%). The highest level of education was in university education (71%). Most of the work experience was related to people with 5–10 years' work experience (50%).

[Table 6] shows the mean and standard deviation scores of the study population in terms of emergency response according to the demographic characteristics of the study population.

There were significant correlation between emergency response score of the study population with gender, educational level, work experience and work unit (P < 0.05). However, there was not significant correlation between awareness emergencies response scores in the study sample and age (P > 0.05 and P = 0.336).

Since the mean scores received (35.36 = 63%) were higher than the mean of the total scores (28 = 50%), the scores of emergency response awareness were evaluated as appropriate and desirable.

Given the mean received scores were higher the mean of the total scores of, awareness emergency response scores in the study sample was rated as appropriate to desirable.


  Discussion Top


In this research, a questionnaire of 56 questions with appropriate validity and reliability was prepared that can be used for measurement emergency response awareness in many communities and workplaces.

To date, low questionnaires have been developed to measure people's emergency response awareness. In most studies, the preparedness of units and operational organizations has been investigated or the focus has been on natural disasters.

In this research, emergency response awareness score was obtained 68% that show public awareness in sample population on emergency and disaster situation is appropriate and desirable. According to Jahangiri et al.'s study (2005), 31.4% of the people has moderate of earthquake response awareness and 37.2% has acceptable, which is consistent with the results of the present research.[24] Jahangiri et al. in a research by title “preparedness, awareness, and risk perception, in staff at Shiraz University of Medical Sciences against earthquake in 2013” found that their preparedness, awareness, and risk perception were at moderate level,[25] which is consistent with recent research results. However, in the research of Jokar et al. (2018), 8.5% of Arak hospital staff had basilar information about the appropriate response to nuclear events, and 6.45% had not nothing information.[26] According to the research by Vosoughi Nayeri et al., only 11.2% of medical university students had a significant level of awareness about health issues at emergency. This was indicative of the low level of awareness of the participants in the study.[11] Furthermore, the results of Rakhshani et al. research showed that most households in Fars province had not awareness against earthquake response and they had high vulnerability to possible earthquake hazards.[27] According to studies by Kurita et al., more than 90% of Sri Lankan residents before the 2004 tsunami had not necessary awareness about the tsunami and its response.[28] Also, in a research by Rezaei et al. (2001), which Arak citizens surveyed about natural disasters reaction at the disasters time, 47.3% of surveyed people had very low information about natural disasters, and only 6.5% had appropriate information.[29] A study by Kihila, who surveyed fire response preparedness in Tanzanian higher education institutions, also assessed the preparedness at a low level.[18] However, according to a research by Glauberman and Qureshi, which surveyed qualitatively the preparedness among citizens of high-rise buildings, the preparedness of people was different.[20]

Therefore, it seems that according to the results of previous research, the awareness and preparedness for emergency and disasters is different, which it may be due to differences in measuring method (questionnaire).

For this reason, the questionnaire developed in this research is expected to cover an acceptable measure of Public Awareness on Emergency Response in the Workplace at pre emergency, during emergency and post emergency situation. As well as this questionnaire covering kinds of emergency such as earthquakes, fires, storms, chemical accidents, and droughts.


  Conclusion Top


This questionnaire with acceptable construct validity and reliability can be used as a valid tool to measure the awareness of people to emergencies reactions in the workplace and other. It is suggested that the forgotten questions in this questionnaire be reviewed by other researchers developed and used in another questionnaire. It is recommended that to measure awareness of emergency response, a questionnaire has to be developed for each emergency situation such as flood, storm, and earthquake. It is recommended that the instrument should be used separately to measure the awareness of people to deal with humanitarian accidents such as traffic accidents, fires and explosions, and radioactive and nuclear accidents.
