摘要

目的采用经典测试理论（CTT）和Rasch测量分析对西班牙普通人群的COVID-19疫苗接种健康素养问卷（CVHL-Q）进行描述，并对其心理测量特性进行检验。研究设计于2022年2月在西班牙普通人群中进行了一项横断面观察性研究。方法对全国代表性的1067名18岁及以上的人进行在线调查。为了测量COVID-19疫苗接种健康素养（CVHL），研究小组开发了一份简短的问卷。使用Rasch分析和CTT对CVHL-Q的心理测量特性进行了探索，并遵循了评估量表验证的推荐实践。结果CVHL指数平均值为34.3 (SD: 11.6，范围：0-50)，39.7%的参与者对COVID-19疫苗的识字率有限（得分≤33分）。仪器显示出令人满意的内部一致性。在判别效度方面，并非所有先验假设都得到证实：年龄越小的个体CVHL-Q得分越低，且与教育水平无关。基于300名参与者的随机子样本的最终模型显示出与Rasch模型的良好拟合（χ2 = 31.9，经Benferroni校正后p = 0.044）和令人满意的信度（PSI = 0.718）。所有项目显示有序阈值和可接受的剩余拟合。CVHL-Q是一份简短的问卷，具有稳健的测量特性，可用于评估人群查找、理解、使用和评估COVID-19疫苗信息的能力。它可能有助于设计宣传运动和评估大流行病的防范工作。

The COVID-19 vaccination health literacy questionnaire (CVHL-Q): Design and validation according to classic psychometric and Rasch analyses

Objectives

This study aimed to describe the COVID-19 vaccination health literacy questionnaire (CVHL-Q) and test its psychometric properties in the Spanish general population using Classic Test Theory (CTT) and Rasch measurement analysis.

Study design

A cross-sectional, observational study was conducted among the Spanish general population in February 2022.

Methods

An online survey was administered to a nationally representative sample of 1067 people aged 18 years or older. To measure COVID-19 Vaccination Health Literacy (CVHL) a short questionnaire was developed by the research team. The psychometric properties of the CVHL-Q were explored using Rasch analysis and CTT, following recommended practices for validation of rating scales.

Results

The CVHL index mean was 34.3 (SD: 11.6, range: 0–50) with 39.7 % of participants showing limited COVID-19 vaccine literacy (score ≤33 points). The instrument exhibited satisfactory internal consistency. Regarding discriminative validity, not all the a-priori hypotheses were confirmed: younger individuals had lower CVHL-Q scores, and no association was found with education level. A final model based on a random subsample of 300 participants showed a good fit to the Rasch model (χ² = 31.9, p = 0.044 with Benferroni correction) and satisfactory reliability (PSI = 0.718). All items displayed ordered thresholds and acceptable residual fit.

Conclusions

The CVHL-Q is a short, questionnaire with robust measurement properties that allow assessing the ability of population to find, understand, use and appraise the information on COVID-19 vaccines. It might be useful in designing communication campaigns and to assess pandemic preparedness.
