A Scoping Review of Health Literacy Measurement Tools in the Context of Cardiovascular Health

Background. Despite the strong link between health literacy and cardiovascular health outcomes, health literacy measurements remain flawed and fragmented. There exists a gap in the knowledge when formulating a valid measurement to capture the broad concept of health literacy. The existence of various tools for health literacy measurement also hampers the availability of health literacy data. Additionally, little research is available on a valid measurement tool for cardiovascular health literacy. Objective. This study aims to provide an overview of the health literacy measurement tools used in the context of cardiovascular health. Method. A scoping review was conducted. Two electronic databases, Medline and Embase, were searched to identify studies that described a tool for the measurement of health literacy in the context of cardiovascular health. Results. After reviewing the available studies, 53 studies met the inclusion criteria. A total of 26 health literacy measurement tools were identified in the studies. Among the 26 tools, 16 used an objective measurement approach, 9 adopted a subjective approach, and 1 employed a mixed approach. Additionally, 28 studies used tools to measure print literacy, 15 studies measured print literacy and numeracy, and 5 studies measured print literacy, oral literacy, and numeracy. Conclusions. STOFHLA, TOFHLA, and REALM were the mostly commonly used tools in the selected studies. The majority of tools were based heavily on reading skills and word recognition. Researchers should focus on the development of more comprehensive and reliable health literacy measurement tool(s) specific to cardiovascular health to assist health care providers to more efficiently and accurately identify people with cardiovascular problems who have inadequate health literacy.
