Psychometric Properties of Health Literacy Instruments and their Medical Contexts in Research with Hispanics/Latinos: a Systematic Review
摘要
Hispanic/Latino populations experience high rates of preventable conditions like heart disease and diabetes, emphasizing the importance of health literacy in promoting informed health decisions and reducing existing disparities. This systematic review aimed to identify frequently used health literacy measures used with Hispanic/Latino adults in the United States, describe the psychometric properties of these measures, and examine the medical contexts and health conditions of the included studies. A comprehensive search across four databases yielded 2,431 studies; After screening, 168 studies met inclusion criteria. Eleven health literacy measures were identified, and the Short Test of Functional Health Literacy (STOFHLA), Newest Vital Sign (NVS), and Brief Health Literacy Screener (BHLS) were the most frequently used. Study medical context and health conditions included general health (23%), diabetes (15%), cancer (14%), among others. While several health literacy measures demonstrated acceptable to good reliability and validity, gaps were identified regarding cultural appropriateness and tailoring to Hispanic/Latino communities. Enhancing health literacy measures is critical to help inform interventions and improve health outcomes in this population.
