Paper III Qualitative research methodology
Objective 1.3 To what extent can findings be generalized from qualitative studies
Generalizability refers to the extent to which research findings are applicable to other populations or samples. • It involves the usefulness of one set of findings in explaining other similar situations. • It is sometimes equated with terms of transferability and external validity. GeneralizationBuilding Context
There is however considerable debate over the nature of the knowledge produced by qualitative methods and whether a term such as generalizability, derived from the quantitative paradigm, can mean the same when used to judge the rigor of qualitative research design, or whether a completely different term should be applied. GeneralizationBuilding Context
There seem to be three sometimes overlapping views in the research literature about qualitative research with regard to its generalizability or not. • One is a relative acceptance that generalizability is not the main purpose of qualitative research, but there are plenty of other good reasons for employing it (e.g. Myers 2000:2); GeneralizationBuilding Context
The second view is that, yes, you can generalize, but if you do, you have to issue cautions about the limited capacity to do so based on the limited numbers (e.g., Benz and Newman 1998), • The third view, named by Stake (1980) in reference to case study research, is one of formalizing the idea that qualitative research is generalizable. GeneralizationBuilding Context
According to Lewis and Richie (2003), qualitative research could distinguish between generalizabilty and the term transferability. • Transferability is applied by the readers of research. Although generalizability usually applies only to certain types of quantitative methods, transferability can apply in varying degrees to many qualitative approaches. “Rethinking” Generalizability
Unlike generalizability, transferability does not involve broad claims, but invites readers of research to make connections between elements of a study and their own experience. • The qualitative researcher can enhance transferability by doing a thorough, unbiased job of describing the research context and the assumptions that were central to the research. “Rethinking” Generalizability:Transferability (Inferential Generalizability)
The person who wishes to "transfer" the results to a different context is then responsible for making the judgment of how sensible the transfer is. • Thus, generalization is the job of the reader, not of the researcher. “Rethinking” Generalizability:Transferability (Inferential Generalizability)
Would the results from the sample (e.g. views and experiences) be similar to those found in the population? • When a qualitative research study accurately depicts the views of the intended population, it is considered representationallygeneralizable. Representational generalization
Representational generalization is not based on statistics and it is not about the prevalence of particular views or experiences, but it is about mapping a range of views or experiences. • It is based on the quality of the research in capturing and interpreting the phenomenon and how far the sample contains diversity and constituencies present in the specific population sampled. • Thus, to some extent, externally valid research is considered to be representationallygeneralizable Representational generalization
Since data for qualitative research are generally drawn from a single setting, qualitative investigators often talk about theoretical (or analytic) generalization (i.e. considering the generalizability of cases to theoretical propositions rather than populations). Inferential Generalization
Murphy and colleagues (1998) described this approach to generalization by citing the case of genie where researchers developed a theory arguing that language acquisition happens during a critical stage of cognitive development. • They argued that, although this was one single case, theoretical generalization could be taken from a well documented rich data filled qualitative study. Inferential Generalization
In conclusion: • Transferability, rather than generalizability is usually the aim of qualitative data • Lincoln and Guba propose that is up to the reader, rather than the original investigator, to determine if the findings can be transferred or applied to another setting. Final Notes
Strengthening “generalizability”: • Rich, thick description: The researcher provides rich, thick description to help place the reader in the context, and to allow the reader to determine if findings are transferable. • Triangulation: Designing a study in which multiple informants and multiple data collection methods are used can strengthen the study’s usefulness for other settings. Final Notes
Strengthening “generalizability”: • Use peer debriefing: Process involves locating a person who reviews and ask questions about the study so that the account will resonate with people other than the researcher. Final Notes
