Abstract

Background: Negative beliefs about vaccines can threaten herd immunity and pandemic control. Although beliefs about vaccines influence vaccination intention, there are no valid instruments that evaluate this in the Latin American population.

Aim: To evaluate the psychometric properties of two scales that measure negative beliefs towards vaccines in general and against SARS-CoV-2 and provide evidence of their association with vaccination intention (convergent validity) in a Chilean sample.

Material and methods: Two studies were carried out. The first included 263 people who answered the beliefs towards vaccines in general scale (CV-G) and the beliefs towards the SARS-CoV-2 vaccine scale (CV-COVID). Exploratory factor analyses were conducted. In the second study, 601 people answered the same scales. Confirmatory factor analyses and structural equation modeling were performed to provide evidence of validity.

Results: Both scales had an unifactorial structure and excellent reliability and showed associations with the intention of vaccination against SARS-CoV-2, providing evidence of convergent validity.

Conclusions: The scales evaluated here are reliable and valid measures that showed associations with vaccination intention in the Chilean population.

[关于对一般疫苗和SARS-CoV-2疫苗信念的两项调查的心理测量学性质]。

背景:对疫苗的负面看法会威胁到群体免疫和大流行的控制。尽管对疫苗的信念会影响疫苗接种意愿，但在拉丁美洲人口中没有有效的工具来评估这一点。目的:评估智利样本中对一般疫苗和对SARS-CoV-2疫苗的消极信念的两个量表的心理测量特性，并提供其与疫苗接种意图(收敛效度)相关的证据。材料和方法:进行了两项研究。第一组包括263人，他们分别回答了对一般疫苗量表(CV-G)和对SARS-CoV-2疫苗量表(CV-COVID)的信念。进行探索性因素分析。在第二项研究中，601人回答了同样的问题。验证性因子分析和结构方程模型提供了有效性的证据。结果:两种量表均具有单因子结构，具有良好的信度，并与接种SARS-CoV-2的意图相关，提供了趋同效度的证据。结论:这里评估的量表是可靠和有效的措施，显示了智利人口中疫苗接种意图的关联。
