Limited health literacy is common among persons infected with HIV and has been linked to poor mental and physical health outcomes, but there are no well-validated screening measures of health literacy in this vulnerable clinical population. The present study evaluates the usefulness of the Newest Vital Sign (NVS) as a brief measure of health literacy in HIV disease.
Seventy-eight HIV+ adults were administered the NVS, Rapid Estimate of Adult Literacy in Medicine (REALM), and Single Item Literacy Screener (SILS). Main criterion variables included plasma HIV viral load, medication management capacity, self-efficacy for medication management, and perceived relationships with healthcare providers.
The NVS showed good internal consistency and moderate correlations with the REALM and SILS. Rates of limited health literacy were highest on the NVS (30.3%) as compared to SILS (6.6%) and REALM (9.2%). A series of regressions controlling for education showed that the NVS was incrementally predictive of viral load, medication management capacity and self-efficacy, and relationships with healthcare providers, above and beyond the REALM and SILS.
The NVS shows evidence of reliability, convergent validity, and incremental criterion-related validity and thus may serve as useful screening tool for assessing health literacy in HIV disease.
健康素养有限在艾滋病毒感染者中很常见，并且与不良的身心健康结果相关，但在这一脆弱的临床人群中，尚无经过充分验证的健康素养筛查措施。本研究评估了最新生命体征（NVS）作为艾滋病毒疾病中健康素养简短测量方法的有效性。
对78名艾滋病毒阳性成年人进行了最新生命体征测试、医学成人识字率快速评估（REALM）和单项识字筛查（SILS）。主要标准变量包括血浆艾滋病毒病毒载量、药物管理能力、药物管理自我效能感以及与医疗服务提供者的感知关系。
最新生命体征测试显示出良好的内部一致性，并且与医学成人识字率快速评估和单项识字筛查具有中等相关性。与单项识字筛查（6.6%）和医学成人识字率快速评估（9.2%）相比，最新生命体征测试中健康素养有限的比例最高（30.3%）。一系列控制教育因素的回归分析表明，最新生命体征测试在医学成人识字率快速评估和单项识字筛查之外，对病毒载量、药物管理能力、自我效能感以及与医疗服务提供者的关系具有递增预测作用。
最新生命体征测试显示出可靠性、收敛效度和递增的标准相关效度的证据，因此可作为评估艾滋病毒疾病健康素养的有用筛查工具。
