Persons living with HIV are particularly vulnerable to COVID-19 and understanding the factors influencing their decision to take the COVID-19 vaccine are crucial. Using the Health Belief Model (HBM), our study examined the role of psychological factors in predicting vaccine intention in patients with HIV. The underlying concept of the HBM is that behaviour is determined by personal beliefs about a disease, and access to strategies to decrease its occurrence. A cross-sectional survey using a structured questionnaire was conducted between August and September 2021 at an HIV clinic in Trinidad. Data on the HBM constructs, namely patient's beliefs about the perceived severity and susceptibility to COVID-19, their perceived benefits of taking the vaccine, and external cues to action, i.e., factors that may motivate them to take the vaccine, were collected. Univariate and multivariable logistic regression analyses were used to examine associations and whether the HBM components were predictors of vaccination intention. In this study, 59.9% of patients indicated their intentions to take the vaccine. Females (OR 0.49, 95% CI 0.30-0.81) were less inclined to take the COVID-19 vaccine compared to males, while Indo-Trinidadian patients with HIV (OR 4.40, 95% CI 1.26-15.3) were more inclined to take the vaccine compared to Afro-Trinidadians. Health beliefs such as having confidence in the vaccine ( = 0.001) and believing in its perceived benefits ( = 0.001) were significant predictors of vaccination intention. Patients who were confident about the vaccine were six times more likely to take the vaccine (OR 6.45, 95% CI 2.13-19.5) than persons who were not confident in it. Having adequate information about the vaccine or the knowledge of others who received the vaccine (OR 1.48, 95% CI 1.03-2.11) were significant cues to action influencing their decision. Guided by the HBM, understanding patient's health beliefs is important in the design of tailored interventions to improve vaccine outcomes. The HBM may also be useful in the design of approaches to increase the uptake of critical HIV prevention, and treatment services.
艾滋病毒感染者尤其容易感染新冠病毒，了解影响他们接种新冠疫苗决策的因素至关重要。本研究运用健康信念模型（HBM），探讨了心理因素在预测艾滋病毒患者疫苗接种意愿方面的作用。健康信念模型的基本概念是，行为由个人对疾病的信念以及获取降低疾病发生几率策略的途径所决定。2021年8月至9月期间，在特立尼达的一家艾滋病毒诊所开展了一项使用结构化问卷的横断面调查。收集了关于健康信念模型构成要素的数据，即患者对新冠病毒感知严重程度和易感性的信念、他们对接种疫苗感知益处的信念，以及行动的外部线索，即可能促使他们接种疫苗的因素。采用单因素和多因素逻辑回归分析来检验关联情况以及健康信念模型各组成部分是否为疫苗接种意愿的预测因素。在本研究中，59.9%的患者表示有接种疫苗的意愿。与男性相比，女性（比值比0.49，95%置信区间0.30 - 0.81）接种新冠疫苗的意愿较低，而与非裔特立尼达艾滋病毒患者相比，印度裔特立尼达艾滋病毒患者（比值比4.40，95%置信区间1.26 - 15.3）接种疫苗的意愿更高。诸如对疫苗有信心（P = 0.001）以及相信其感知益处（P = 0.001）等健康信念是疫苗接种意愿的重要预测因素。对疫苗有信心的患者接种疫苗的可能性是对疫苗无信心患者的六倍（比值比6.45，95%置信区间2.13 - 19.5）。获得关于疫苗的充分信息或了解其他接种过疫苗的人的情况（比值比1.48，95%置信区间1.03 - 2.11）是影响其决策的重要行动线索。在健康信念模型的指导下，了解患者的健康信念对于设计针对性干预措施以改善疫苗接种效果至关重要。健康信念模型在设计提高关键艾滋病毒预防和治疗服务利用率的方法方面可能也很有用。
