The prevalence of preventive behaviors and associated factors during the early phase of the COVID-19 pandemic among Iranian People: Application of a Health Belief Model

INTRODUCTION: Coronavirus disease 2019 (COVID-19) has developed into a severe public health concern. The present study was aimed to evaluate the related preventive behaviors to COVID-19, and associated factors among Iranians based on the constructs of the Health Belief Model (HBM). METHODS: This cross-sectional study was conducted between March and April 2020 among Iranians. Data of 1,020 people were collected by a self-administered questionnaire based on the constructs of HBM and also a demographics questionnaire. Simple and multivariable linear regression models were used to determine the predictors of preventive behaviors concerning COVID-19. A P-value of less than 0.05 was considered significant. RESULTS: The mean score of preventive behaviors concerning COVID-19 was 4.27 (standard deviation = 0.60). 40.6% (95% CI: 38.6-43.7%), and 56.5% (95% CI: 53.4-59.5%) of the participants exhibited a high, and moderate level of preventive behaviors, respectively. 75.1% of the participants would always/often wear face masks out home or in crowded places. The most common preventive behaviors were using of personal belongings in the workplace or at home (96.1%) and staying at home except for very necessary or for work (92.9%). Results showed that all six HBM constructs, i.e., perceived susceptibility (B = 0.07, P < 0.001), perceived severity (B = 0.08, P < 0.001), perceived benefits (B = 0.25, P < 0.001), perceived barriers (B = -0.12, P = 0.001), cues to action (B = 0.07, P < 0.001), and self-efficacy (B = 0.26, P < 0.001) were significant predictors of related preventive behaviors to COVID-19. Female gender was another predictor of preventive behaviors (B = 0.18, P < 0.001). CONCLUSIONS: This study demonstrated the effectiveness of HBM constructs in predicting COVID-19 preventive behaviors. Therefore, the model as a framework for designing training programs for improving health behaviors among Iranians during the COVID-19 pandemic seems to be helpful.
