Background: Dysfunctional attitudes are biased assumptions and beliefs that the subject has toward himself, his surroundings, and the future world. Objectives: The present study aimed to predict COVID-19 preventive healthy behaviors based on dysfunctional attitudes in five countries. Methods: This was a descriptive, correlational study, and the statistical population of the study included all individuals over the age of 18 years residing in Iran, Australia, England, Sweden, and Canada. Subjects were selected by the voluntary sampling method in the Spring of 2020. In total, 498 electronic questionnaires encompassing three sections of demographic characteristics, dysfunctional attitude scale (1987), and COVID-19 preventive health behaviors questionnaire (2020) were completed online. In addition, data analysis was performed in SPSS version 21 using Pearson’s correlation coefficient and stepwise multiple regression. Results: In this study, there was a significant negative relationship between dysfunctional attitudes and COVID-19 preventive healthy behaviors (P < 0.001). In addition, perfectionism, gender, and age predicted healthy behaviors (P < 0/001). The results of the comparison of Iran with other countries also demonstrated a significant reverse correlation between dysfunctional attitudes and healthy behaviors (P < 0.001). Moreover, there was a significant association between marital status, age, level of education, gender (P < 0.001), and economic status (P < 0.05) with healthy behaviors in Iran while no significant relationship was observed in other countries studied in this regard. Conclusions: It is suggested that workshops on changing dysfunctional attitudes and strengthening positive attitudes in community members be held in-person or via cyberspace before or during the occurrence of crises such as the COVID-19 outbreak.

Background: Persuasion is a method used to correct and modify the attitude and behaviors of community members to protect collective benefits, especially during crises. Objectives: The present study aimed to predict COVID-19 preventive behaviors based on persuasion techniques in five countries. Methods: This descriptive, correlational study was conducted on the population aged more than 18 years in Iran, Australia, the United Kingdom, Sweden, and Canada. The sample size determined by Morgan’s table was 498 individuals who were selected via convenience sampling in the spring of 2020. Data were collected online using a Demographic Questionnaire, a Persuasion Scale (2020), and the Questionnaire of Healthy Preventive Behaviors for COVID-19 (2020). The inclusion criteria were the age of more than 18 years and basic literacy, and the exclusion criterion was incomplete questionnaires. Data analysis was performed in SPSS version 21 using Pearson’s correlation-coefficient and multiple regression analysis. Results: A positive significant correlation was observed between persuasion techniques and healthy preventive behaviors for COVID-19 (P < 0.001). Among the components of persuasion, fear, interest in the messenger, frequency of the message, and reliability of the messenger could most significantly predict healthy behaviors (P < 0.001). Conclusions: According to the results, the mass media and authorities could enhance the effectiveness of their agenda by identifying the influential factors in the success of persuasion techniques. These findings could be beneficial to social psychiatrists, authorities, and the mass media.
