Individual differences in one's perceived vulnerability to infectious diseases are implicated in psychological distress, social and behavioral disease avoidance phenomena. The Perceived Vulnerability to Disease Questionnaire (PVD) is the most extensively used measure when it comes to assessing subjective vulnerability to infectious diseases. However, this measure is not yet accessible to the Portuguese population. The present study aimed to adapt and validate the PVD with 136 Portuguese participants.
Factorial, convergent and discriminant validity (of both the scale and between each factor), and reliability analysis were assessed.
A modified bifactorial model, comprised of Perceived Infectability and Germ Aversion factors, was obtained, with acceptable goodness-of-fit indices, adequate convergent and discriminant validity, and good internal consistencies.
Overall, the 10-items European-Portuguese PVD appears to be a reliable and valid measure of one's perceived vulnerability to disease, with potential relevance for application in both research and clinical practice pertaining to disease-avoidance processes.
个体对传染病易感性的感知差异与心理困扰、社会和行为疾病回避现象有关。当涉及评估对传染病的主观易感性时，疾病感知易感性问卷（PVD）是使用最广泛的测量方法。然而，该测量方法目前还无法在葡萄牙人群中使用。本研究旨在用 136 名葡萄牙参与者对 PVD 进行适应性和验证。
评估了因子、收敛和区分效度（包括量表和每个因子之间）以及可靠性分析。
获得了一个修正的双因素模型，包括感知易感性和厌恶细菌两个因素，具有可接受的拟合优度指数、适当的收敛和区分效度以及良好的内部一致性。
总体而言，10 项欧洲-葡萄牙 PVD 似乎是一种可靠且有效的疾病感知易感性测量方法，对于疾病回避过程的研究和临床应用具有潜在的相关性。
