Background: Effective vaccination among children is essential for controlling the COVID-19 pandemic. Understanding the factors influencing parental decision-making is critical to improving vaccine uptake among children. This study aimed to determine parents’ intentions regarding COVID-19 vaccination for children aged 3–18 years in Guilan Province using the BASNEF model.
Methods: This analytical cross-sectional study included 688 parents selected using multistage cluster random sampling. Data were collected using a structured questionnaire comprising demographic information, knowledge, and BASNEF model constructs. Data were analyzed using SPSS software, version 21, and the significance level was set at P<0.005.
Results: Stepwise multiple regression analysis revealed that subjective norms (P<0.001), attitudes (P<0.001), knowledge (P<0.001), maternal decision-making (P=0.001), joint parental decision-making (P<0.001), parental vaccination status (P=0.03), and having a vaccinated child (P=0.002) collectively explained 56% of the variance in parental behavioral intentions.
Conclusion: Knowledge, attitudes, subjective norms, and decision-making patterns strongly influence parents’ intention to vaccinate children against COVID-19. The BASNEF model identifies these factors and guides targeted strategies to improve vaccine uptake.
