Abstract

The 7C of the vaccination readiness scale provides a score to evaluate the willingness and readiness to get vaccinated (vaccination readiness). This cross-sectional study clarifies the cutoff vaccination readiness score to determine whether an individual is willing to be vaccinated. We conducted an online survey of 774 participants. The vaccination readiness scores for the full and short survey versions were calculated. The coronavirus disease 2019 vaccination status was used to determine whether the participant was willing to be vaccinated. Receiver operating characteristic curve analysis was performed using the Youden index. The Youden Index was at its maximum when the cutoff score was 4.02 for the full version (area under the curve [AUC]:0.94) and 4.07 for the short version (AUC:0.90). Vaccination readiness scores greater than 4 on both the full and short version may indicate a willingness to be vaccinated. This cutoff value facilitates the interpretation of the 7C scale results.
