Risk Perception and Behavioral Responses Related to COVID-19 Among the Iranian General Population: An Application of the Extended Parallel Process Model
Abstract Background: The novel coronavirus disease 2019 (COVID-19) has emerged as a major global public health challenge. Psychosocial and cultural factors affect adherence to health advice. This study aims to investigate how people have perceived the COVID-19 outbreak using the components of EPPM (i.e., recommended response efficacy, self-efficacy, susceptibility, and severity) and how their behavioral responses contributed to the prevention and control of the disease.Methods: This cross-sectional study was conducted online in Iran in March and April. Data were collected using an electronic questionnaire via Porsline. Participants were recruited using online applications and posts on platforms such as Telegram, WhatsApp, and Instagram asking people to take part. The posts asked people aged 15 years and over to take part in a study investigating the control and prevention of COVID-19. EPPM was used to develop a questionnaire measuring the risk perception of and behavioral responses to COVID-19. We used a 29-item, standardized, structured format. Analysis of variance (ANOVA) and t-tests were used to compare groups. In all tests, a value of p < 0.05 was considered statistically significant.Results: A total of 3,727 individuals with a mean age (SD) of 37.0 (11.1) years participated in the study. The results by age category revealed significant progressive increases in perceived susceptibility, perceived self-efficacy, and avoidance response scores, particularly among those aged 60 and over. A total of 56.4% of participants were engaging in danger control processes and 43.6% in fear control processes. Women had significantly higher scores than men for self-efficacy, reactance, and avoidance defensive responses; men had higher perceived susceptibility scores for COVID-19 than women. We also found significantly higher scores for behavioral responses among people with advanced educational backgrounds. Conclusion: more than half of all participants motivated by danger control. This indicates that more than half of participants had high perceived efficacy (i.e., self-efficacy and response efficacy) scores. Self-efficacy scores were significantly higher among participants who were older, female, single, lived in rural areas, or had good economic status. The results of our study suggest that socioeconomic and demographic factors are the main determinants of psychological responses to controlling the COVID-19 pandemic.
