What are the challenges in generalising findings from qualitative studies?

Generalising findings from qualitative studies can be challenging due to their context-specific nature, small sample sizes, and subjective interpretations.

Qualitative studies often focus on understanding phenomena within specific contexts. They delve deep into the experiences, perceptions, and behaviours of individuals or groups in their natural settings. This context-specific nature of qualitative research makes it difficult to generalise the findings to other settings or populations. For instance, a study exploring the experiences of teachers in a rural school may not be applicable to teachers in urban settings. The unique characteristics of the participants and the context in which the study is conducted can significantly influence the findings, limiting their generalisability.

Another challenge is the typically small sample sizes used in qualitative research. These studies often involve in-depth interviews, focus groups, or case studies, which require a significant amount of time and resources. As a result, researchers usually work with a small number of participants. While this allows for a deep understanding of the participants' experiences, it also means that the findings may not be representative of the larger population. The small sample size can limit the ability to make statistical inferences and generalise the findings.

Subjectivity is another inherent characteristic of qualitative research that can pose challenges to generalisation. Qualitative studies often rely on the researcher's interpretations of the data. These interpretations can be influenced by the researcher's personal biases, beliefs, and experiences. This subjectivity can lead to different interpretations of the same data by different researchers. Moreover, the participants' responses can also be influenced by their relationship with the researcher, further adding to the subjectivity of the findings. This makes it difficult to replicate the study and generalise the findings.

Lastly, qualitative research often aims to generate rich, detailed data rather than to test hypotheses or make predictions. The goal is to gain a deep understanding of a phenomenon, not to produce findings that can be generalised. Therefore, the very purpose of qualitative research can be seen as a challenge to generalisation. However, it's important to note that generalisation is not always the goal of research, and qualitative studies can provide valuable insights that quantitative studies may not be able to capture.
