Abstract

Background

Bangladesh has consistently prioritized vaccination to address health issues. While high hesitation continues to be a significant barrier to vaccination success, vaccination fear is a distinct psychological construct that might affect the decision to vaccinate. Despite this, no valid and reliable tool exists to assess vaccination fear in the Bangladesh population.

Aim

We aim to validate culturally and adapt the Vaccination Fear Scale (VFS-6) in Bangladesh.

Method

We conducted a cross-sectional study among 1098 participants using a non-random convenient sampling method. A total of 1089 were included in the study (mean age = 34.28 years, SD = 12.78), with the majority being female (55,5 %). Descriptive statistics were carried out to get an overall idea of the dataset, and inferential analysis including exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Rasch statistics, were employed to validate the VFS-6 Bangla version.

Result

The internal consistency of the overall VFS-6 scale was 0.818.I In CFA substantial loadings were observed, ranging from 0.713 to 0.935. The significant correlation between the somatic and cognitive factors of VFS-6 was 0.48, and the correlation with DASS-21 was weak but significant (r = 0.29). CFA indicated a good model fit. Rasch analysis demonstrated good item and person separation reliability (0.82 and 0.80, respectively), with a substantial relationship between scores, ability, and probability.

Conclusion

The Bangla version of the VFS-6 has proven to be a reliable and valid measure to assess vaccination fear.

孟加拉版疫苗接种恐惧量表（VFS-6）的心理测量特性：经典和现代测试理论的双重方法

孟加拉国一直把接种疫苗作为解决健康问题的优先事项。虽然高度犹豫仍然是疫苗接种成功的重大障碍，但疫苗接种恐惧是一种独特的心理结构，可能会影响疫苗接种的决定。尽管如此，没有有效和可靠的工具来评估孟加拉国人口对疫苗接种的恐惧。我们的目标是在孟加拉国从文化上验证和调整疫苗接种恐惧量表（VFS-6）。方法采用非随机方便抽样方法，对1098名被试进行横断面调查。共纳入1089例患者，平均年龄34.28岁，SD = 12.78，以女性居多（55.5%）。采用描述性统计获得数据集的总体思路，并采用探索性因子分析（EFA）、验证性因子分析（CFA）和Rasch统计等推理分析对VFS-6孟加拉语版本进行验证。结果整体VFS-6量表内部一致性为0.818。在CFA中观察到大量的负荷，范围从0.713到0.935。VFS-6的躯体因子与认知因子的相关性为0.48，与DASS-21的相关性虽弱但显著（r = 0.29）。CFA表明模型拟合良好。Rasch分析显示了良好的项目和人分离信度（分别为0.82和0.80），得分、能力和概率之间存在实质性的关系。结论孟加拉国版本的VFS-6已被证明是评估疫苗接种恐惧的可靠和有效的措施。
