Abstract:
Objective To systematically explore the psychological decision-making pathways influencing influenza vaccination intentions among Chinese residents, and to identify the key driving factors in the transformation process from cognition and belief to final intention. Methods This study employed a cross-sectional survey design and surveyed 303 Chinese residents via an online questionnaire. Three independent multiple linear regression analyses were conducted to sequentially test the path models of “Knowledge → Beliefs”(Stage 1), “Beliefs → Attitude”(Stage 2), and “Attitude → Intention” (Stage 3). The role of demographic variables in each stage was also analyzed. Results In Stage 1, influenza knowledge was a significant predictor of forming key beliefs, significantly positively predicting the social responsibility belief of “being responsible for family” (B=0.242, P < 0.001), and significantly negatively predicting “doubt about vaccine effectiveness” (B=−0.210, P < 0.001). In Stage 2, the public's vaccine-supportive attitude was significantly influenced by “social responsibility” (B=0.234, P < 0.001), “doubt about vaccine effectiveness” (B=−0.153, P=0.002), traditional media reports (B=0.233, P=0.002), and place of residence (B=−0.265, P=0.005). In Stage 3, vaccine-supportive attitude was the core predictor of future vaccination intention (B=0.597, P< 0.001), confirming its key mediating role. Additionally, previous vaccination history (B=0.143, P=0.001) and recommendations from friends and family (B=0.184, P=0.018) were two independent driving factors for vaccination intention. Specific occupations also showed significant influence in this final decision-making stage. Conclusion The public's decision-making process for influenza vaccination is a hierarchical transformation process from “Knowledge-Beliefs” to “Attitude" and then to “Intention.” Public health intervention strategies should implement targeted interventions based on the status of key driving factors at different stages..
