The 7C of the vaccination readiness scale measures the 7 psychological components that structure people's vaccination readiness. We aimed to develop the Japanese version of this scale (7C scale Japanese version) and to assess its validity and reliability.
The full and short versions of 7C scale Japanese were developed based on translation guidelines provided by the ISPOR Task Force. An Internet survey, including 709 participants, was performed to assess the scale's validity and reliability within a confirmatory factor analysis (CFA) framework (men: 38.8%, age range: 20-92 years). Invariance analysis using multiple-group CFA was conducted to test cross-cultural validity between participants in this study and those in the 7C original version study. McDonald's omega and intraclass correlation coefficient were calculated to evaluate internal consistency and test-retest reliability, respectively. To clarify the criterion validity, regression analysis, with previous COVID-19 vaccination status as the dependent variable, was performed to calculate pseudo R.
The 7C scale Japanese version exhibited good content validity, structural validity, configural invariance, and criterion validity. The results showed good internal consistency, and test-retest reliability, except for the "calculation" component.
7C scale Japanese version exhibited acceptable reliability and validity; however, "calculation" may be a less reliable subscale.
接种准备量表的 7C 衡量了构成人们接种准备的 7 个心理组成部分。我们旨在开发该量表的日文版（7C 量表日文版），并评估其有效性和可靠性。
根据 ISPOR 工作组提供的翻译指南，制定了 7C 量表日文的完整和简短版本。在确认性因素分析（CFA）框架内进行了一项包含 709 名参与者的互联网调查，以评估量表在内部一致性和测试-重测可靠性方面的有效性和可靠性（男性：38.8%，年龄范围：20-92 岁）。使用多组 CFA 进行不变性分析，以测试本研究参与者与 7C 原始版本研究参与者之间的跨文化有效性。计算 McDonald's omega 和组内相关系数，分别评估内部一致性和测试-重测可靠性。为了明确效标效度，进行了回归分析，以以前的 COVID-19 疫苗接种状况为因变量，计算伪 R。
7C 量表日文版具有良好的内容效度、结构效度、组态不变性和效标效度。结果显示，除了“计算”部分外，该量表具有良好的内部一致性和测试-重测可靠性。
7C 量表日文版具有可接受的可靠性和有效性；然而，“计算”可能是一个不太可靠的分量表。
