Objective To develop the influenza vaccine hesitation scale for the elderly aged 60 and above and evaluate its applicability. Methods Based on the Chinese version of the parents' hesitation scale for children's influenza vaccination, combined with the characteristics of the elderly population, the influenza vaccine hesitation scale for the elderly aged 60 and above was developed, and the reliability and validity of the scale were evaluated. Results The scale finally included 3 dimensions and 14 items, the score of the total scale was 32.82 ±7.99, and the correlation coefficient between each item and the score of the total scale was between 0.20 and 0.87 (all P < 0.05). Exploratory factor analysis showed that the Kaiser -Meyer-Olkin (KMO) value of the scale was 0.916 (x²approximation = 14 315.26, P<0.05). Confirmatory factor analysis showed that the cumulative variance contribution rate of 14 common factors was 80.6%, GFI=0.909, IFI=0.961, TLI =0.952, and CFI = 0.961, indicating that the overall fitness and structural validity of the model were good. Taking whether the elderly were vaccinated with influenza vaccine or not in the influenza season in 2022, the total vaccine hesitation score and the scores of "confidences", "risk" and "support" were significantly correlated with the school standard (all P < 0.05). The Cronbach's a coefficient of the scale was 0.859, indicating that the internal consistency reliability of the scale was high. Conclusion The influenza vaccine hesitation scale for the elderly developed in this study is good in reliability, validity and applicable stability, which can be used to evaluate the hesitation level of influenza vaccine in people aged 60 and above.
