Researching the perceptions of Vietnamese migrant caregivers for an oral health literacy study in Australia

This case study focuses on gaining access to Vietnamese migrant caregivers in South Western Sydney, Australia, for an oral health literacy study. We chose to approach this topic from the phenomenological framework which provided us with an opportunity to examine and understand non-English-speaking parents'/caregivers' perceptions related to existing oral health promotion materials. The case study starts by giving a brief overview of the research project and the complexities of carrying out a research project with migrant populations, followed by detailed description of the research process, access to participants, stakeholder involvement, building trust with participants, and data collection methods. We were able to obtain in-depth understanding using multiple data collection methods such as participant observation and indepth interviews. By applying maximum variation technique in a stratified purposive sampling, we managed to capture a comprehensive sample of Vietnamese migrant caregivers in Greater Western Sydney. Therefore, we therefore recommend employing multiple qualitative techniques to conduct qualitative research with participants from non-Englishspeaking backgrounds.
