In early December 2019, the new coronavirus-2019 (COVID-19) was first reported (
1). On March 11, 2020, the World Health Organization (WHO) officially announced COVID-19 as a pandemic (
2). COVID-19 directly affects the respiratory system, and the patients present with major symptoms such as fever, coughing, common fatigue, pneumonia, and abnormal chest CT-scan findings (
3).
Public compliance with hygienic principles is considered to be an important preventive measure against COVID-19 and infection control (
4). Currently, COVID-19 is a severe global health crisis, prompting communities, organizations, and countries to take initiative against its spread (
5). According to the WHO (1998), self-care refers to behaviors that aim to protect the mental and physical health of individuals, meet their social and psychological needs, prevent diseases and adverse events, improve diseases and chronic conditions, and maintain health after a chronic disease or discharge from the hospital. Participation and staying accountable are key to self-care so that proper behaviors could control complications (
6) or prevent disease.
In pandemics such as COVID-19, self-care encompasses the healthy behaviors recommended by the WHO, and everyone must comply with these principles as unhealthy behaviors adversely affect the health of the individual and the community; each person is responsible for their health and the health of others.
After the COVID-19 pandemic was confirmed, the WHO listed healthy behaviors such as frequent hand washing, wearing a face mask, physical distancing, and refraining from staying in indoor spaces for a long time. By adhering to these recommendations, individuals could protect themselves against the disease, while also preventing the spread of COVID-19 to others. However, people respond differently to a new phenomenon and often have difficulty accepting new principles and recommendations, with some resisting new requirements and rules. Therefore, governments and authorities must persuade the community to follow proper principles under such circumstances.
Persuasion or change of perception is a foundation of social support. Changing social life is not only affected by behaviors, but also by changes in the perspectives, beliefs, and attitudes of individuals and groups (
7). Persuasion is a conscious attempt at changing the beliefs, attitudes, and behaviors of community members (
8). Since the early 20th century, the concept of persuasion has been systematically explored in the field of social psychology (
9).
Patrick et al. reported three components of experience, subject, and language to be influential in the persuasion of individuals to accept or reject a phenomenon (
10). Various models have also been proposed for behavioral and attitude changes in individuals, and the shared features of these models are raising awareness and conveying the message. In this context, the message could change, promote, or reject one’s attitude, thereby leading to behavioral changes. Therefore, persuasion techniques play a pivotal role in conveying the message and changing attitudes on a large scale (
11).
In the present study, we selected Hovland’s persuasion model as the framework. The model introduces the four main components of persuasive communication. The first component is the source of the message; in this regard, the term ‘source’ refers to all the individuals (real person, legal person, organization, social group, author, or anchor) who are involved in presenting and conveying the message. In addition, the source has five qualities of expertise, reliability, attraction, similarity, and power (
12). According to the literature, community members often consider the words and claims of experts and knowledgeable individuals to be more reliable in regards to a specific issue (
9,
13,
14). Positive disposition could also be attained by other variables such as using attractive sources, which facilitates persuasion along with the variable of credibility (
9). Furthermore, the similarity of the message source with the audience to be another influential factor in the process of attitude change (
15).
Message features are another important component in this regard, which include the understandability of the message, number of deductions, the partiality of the message, the conclusion of the message, mentioning the source at the beginning/end of the message, order of presenting the message, message repetition and its variations, speech principles, emotional tone, and framing of the message (
16). Fear is an emotion commonly used in the process of persuasion, which is reported to be highly effective in this regard (
17).
The third component is the means of conveying the message (tools). In research compared visual, auditory, and printed media with face-to-face communication, concluding that the latter is more effective in stimulating the audience and the findings indicated that simple messages could be conveyed to the audience more effectively through visual media compared to auditory and printed media. On the other hand, complex messages are conveyed more effectively through printed media (
9). In another study, Keshavarz and Yazdkhosti reported that a pattern introduced through media is more effective in the attention and changing of beliefs, attitudes, and behaviors of the audience (
18). According to the literature, properly written messages play a key role in changing health-related behaviors such as weight control (
19), quitting smoking (
20), and medication control (
21).
Message recipients are the fourth component of persuasion. The persuasion of message recipients is influenced by several factors, such as their intelligence, education level, gender, self-esteem, elitism and purposive processing, age, engagement with the subject, personality traits, and belief systems (
16). The audience population has wide-ranging and intricate characteristics, which could determine the considerations for the method of designing and codifying the message, representing the source, and ultimately choosing the proper media. Therefore, adequate knowledge of audience characteristics enhances the effectiveness of persuasive communication (
15). A study in this regard indicated that under specific circumstances, personality traits may play a key role in targeting persuasive messages.
Gender is an important influential factor in persuasion (
22), and message repetition is another significant parameter in this regard. Studies regarding memory and news processing in individuals have shown that transitory stimuli and concepts fail to affect the human cognitive system and often remain unlearned or will be forgotten shortly after they are conveyed (
23). In this regard, Esmi et al. evaluated the level of watching commercials and compliance with safety measures, reporting that safety measures are observed better by the individuals who watch commercials more frequently (
24). Furthermore, studies show that 96.1% of students choose the food items that they have come to know through commercials (
25), while 82% of respondents in another study considered receiving three messages per day to be favorable regarding a specific service/product (
12).
Communicable diseases such as COVID-19 have imposed substantial costs on the healthcare system of Iran and several other countries, while also causing undeniable human-related consequences and complications. For optimal results, preventive measures and increasing self-care skills are known to be more effective compared to other attempts (
26). In the COVID-19 pandemic, specific and new attitudes must be adopted by individuals in terms of lifestyle and self-care in order to prevent the disease. As mentioned earlier, the WHO has published a list of healthy behaviors for the current pandemic, which must be promoted by governments to persuade each nation to comply with these rules.
In Iran and other countries, education on the prevention of COVID-19 has become increasingly important, with the mass media making the greatest endeavors in this regard. In the context of education and awareness, proper skills and techniques of persuasion could effectively correct and modify the behaviors of community members. By obtaining more information about the influential factors in this regard, the mass media could enhance the efficacy of their agenda. Therefore, the recognition of persuasion techniques could indirectly affect the prevention of COVID-19.
