An overview of qualitative research methodology for public health researchers

Qualitative research methodology enables researchers to explore social and behavioural issues related to public health that are not achievable with quantitative methods. Several complex public health issues can be better understood by exploration using qualitative methodologies. However, these methodologies are underutilized in public health research particularly in developing countries. This paper aims to introduce qualitative research to students and researchers in public health in developing countries and to encourage its use in research by presenting an overview of how to undertake a qualitative research study. Key aspects of this methodology include choosing and working within a theoretical framework, recruitment of participants, following the right process of data analysis, and presentation of findings for publication.
