Accurate data collection is a cornerstone of epidemiological research. Bilingualism plays a critical role in this process by breaking down language barriers. When researchers can communicate directly with participants in their native language, it reduces the risk of miscommunication and misinterpretation, leading to more reliable data. Additionally, bilingualism enables the inclusion of non-English-speaking populations in studies, which enhances the representativeness and generalizability of the research findings.
