A new communicable disease called coronavirus disease or COVID-19 emerged in Wuhan, China in mid-September, 2019, and rapidly spread throughout this country in a few days for various reasons (
1) and then similar cases were reported in most of the other countries. On March 11th, 2020, the World Health Organization (WHO) announced the COVID-19 outbreak a pandemic (
2). COVID-19 is an acute severe respiratory disease that is closely related to SARS-CoV-2 (
3). Early symptoms include fever, cough, respiratory problems, and severe cases experience pneumonia, acute respiratory syndrome, and eventually mortality (
4). To date, no successful vaccine or antiviral drug has been clinically confirmed for the treatment of COVID-19, and the only way to prevent the disease and control the infection is adherence to hygiene practices by the public (
5). The COVID-19 disease is an important global crisis that has necessitated individuals, organizations, and countries to carry out necessary measures to deal with the phenomenon (
6).
In general, health behaviors and habits of individuals affect the incidence and severity of diseases (
7). The WHO (1998) defines self-care as the actions performed by an individual to maintain their psychological and physical health, meet their social and mental needs, prevent diseases and incidences, improve chronic illnesses and conditions and protect their health after an acute illness or hospital discharge (
8). Core principles on self-care include participation and acceptance of responsibility by the individual so that disease complications could be controlled (
9) or the emergence of a disease could be prevented by performing the related behaviors correctly. During a pandemic in society, such as COVID-19, self-care includes a series of health behaviors announced by the WHO that should be performed by all people. This is mainly due to the fact that the unhealthy behaviors of one person not only affect their own health but also have impacts on the health of other people in the community. Therefore, everyone is responsible for taking care of themselves and others. People may not perform healthy behaviors for various reasons; firstly, the person who should take care of himself has not accurately comprehended the problem. Secondly, he does not know the correct ways to deal with the problem, and thirdly, he may not that motivated to perform self-care behaviors (
10).
Self-care is a function of factors such as knowledge, motivation, attitude, performance and skill, individual beliefs, and culture of society (
11,
12). A reduction in social interactions always exposes community members to various stressors, which affects their functioning in society and satisfaction with life. These stressors can be a combination of internal stimuli, such as personality and beliefs, which lays the foundation for failure, and external factors, including environmental stressors (
13). According to cognitive models, some of the factors affecting the emergence of depression and anxiety include cognitive distortions and dysfunctional attitudes. Dysfunctional attitudes are biased assumptions and beliefs that the subject has toward himself, his surroundings, and the future world (
14). In addition, dysfunctional attitudes are considered as predisposing factors in the onset of depressive episodes directly or as a factor of individual vulnerability due to environmental stressors (
15). These attitudes emerge immediately after the occurrence of unfortunate and negative life events and stimulate a negatively-biased pattern of information processing. In other words, they are determined by negative thinking patterns. These negative attitudes can be among the health dysfunctional factors (
16). According to Beck, dysfunctional attitudes are inflexible and perfectionist standards used by the individual to judge themselves and others. These attitudes are considered dysfunctional due to being extreme, resilient, and inflexible (
17). Negative beliefs and thoughts that people form put them under stress and decrease their quality of life in various ways (
18). Moreover, dysfunctional attitudes negatively affect individual, social and occupational performance (
19). Studies have reported a positive association between dysfunctional attitudes and depression (
20).
Attitudes of people determine their behaviors (
21). According to the theory of planned behavior, the intention to perform a self-care behavior is determined by three components: the attitude of the individual (an individual's assessment of the potential or expected outcome of performing a self-care behavior), subjective norms (the perceived social pressure to perform or not to perform the behavior), and perceived behavioral control (a person's understanding of the simplicity or difficulty of performing a self-care behavior) (
22). Studies show that attitude affects individuals’ self-care against their disease (
23-
25). In addition, research has confirmed the relationship between attitude and behavioral intention and, ultimately, performing healthy behaviors (
26,
27). A previous study was performed to evaluate the effect of self-care on dysfunctional attitudes, the results of which were indicative of a decrease in the mentioned attitudes after self-care training (
19). These results demonstrated a correlation between dysfunctional attitudes and self-care. Various studies have shown a relationship between the demographic characteristics of individuals and healthy behaviors. In this regard, a significant association has been reported between self-care behaviors and variables of age, marital status, level of education, and economic status (
19,
28,
29).
Not only do diseases such as COVID-19 impose huge financial burdens on the health systems of all countries, but also, they are associated with undeniable human consequences and complications. Implementing preventive measures and increasing self-care skills is more effective than other measures in order to achieve favorable results (
30). Given the negative role of dysfunctional attitudes in social and individual performance, it is crucial to conduct research on the relationship between these attitudes and healthy behaviors. While numerous studies have shown the association between attitude and healthy behaviors, no comprehensive research has been conducted on the relationship between demographic characteristics, dysfunctional attitudes, and performing healthy behaviors in such crises. With this background in mind, the present study aimed to evaluate the demographic characteristics and dysfunctional attitudes of individuals, which, according to the scientific background of the field, seem to be related to healthy behaviors that prevent COVID-19.
