Qualitative Rigour
Qualitative research is sometimes criticized for being biased, small scale, anecdotal, or lacking rigour. However, when conducted with appropriate methodological care, it is impartial, in-depth, valid, dependable, and rigorous. Just as quantitative research is evaluated through concepts such as validity and reliability, qualitative research is assessed through the broader concept of trustworthiness. Watch the video below to get a brief overview on trustworthiness in qualitative studies.

Reflexivity and Rigour
In qualitative research, establishing trustworthiness is essential. Reflexivity—the ongoing examination of how a researcher’s background, assumptions, and perspectives influence the research—plays a key role in achieving rigour. This approach aligns with the framework of Lincoln and Guba (1985), who proposed criteria for evaluating the trustworthiness of qualitative research.
Rigour is commonly assessed using four criteria identified by Lincoln and Guba (1985):
- Credibility → Are the findings believable and true to the participants’ experiences?
- Dependability → Would someone else looking at the same data see similar patterns?
- Confirmability → Are the results grounded in the data, not just the researcher’s opinions?
- Transferability → Can the insights be useful in other settings or situations?
These criteria are strengthened through transparent and systematic research practices. Credibility can be enhanced through strategies such as prolonged engagement, triangulation, peer debriefing, and member checking. Transferability is supported by providing rich, detailed descriptions that allow readers to assess applicability to other settings. Confirmability is established by documenting analytic decisions and maintaining a clear link between data and interpretations. Dependability is achieved through a logical, well-documented research process that can be followed and evaluated by others.
Reflexivity underpins all of these criteria by making the research process more transparent. By continuously reflecting on how their perspectives shape data collection and analysis, researchers help ensure that findings remain grounded in participants’ voices, thereby strengthening the overall trustworthiness of the study (Lincoln & Guba, 1985).
Dr. Fehr Reflection: 
Think about a clinical situation where your own bias or experience could shape how you understood a patient’s story. How might you check yourself so the patient’s voice stays central? That’s reflexivity supporting rigour.
The following has more detail: Criteria used to establish trustworthiness include credibility, transferability, confirmability, and dependability.
- Credibility refers to the extent to which a study’s findings are believable, trustworthy, and accurately represent participants’ experiences. It reflects the connection between what participants actually shared and how the researcher portrays those perspectives. Credibility can be strengthened through prolonged engagement with participants, persistent observation, triangulation of data and researchers, and peer debriefing to provide external checks on the research process. Member checking, which involves returning findings or interpretations to participants to confirm their accuracy, is another important strategy for enhancing credibility.
- Transferability relates to how well the findings of a study can be applied to other settings or contexts. Rather than claiming universal generalizability, qualitative researchers support transferability by providing rich, detailed descriptions of the research setting, participants, and processes. These descriptions allow readers to determine whether the findings may be relevant or applicable to their own contexts.
- Confirmability focuses on ensuring that the findings are grounded in the data rather than influenced by the researcher’s personal assumptions or viewpoints. To demonstrate confirmability, researchers show how interpretations were reached by documenting analytic decisions, theoretical choices, and methodological steps. This transparency makes it clear that the conclusions arise from the participants’ accounts rather than the researcher’s preferences.
- Dependability refers to the stability and consistency of the findings over time. A dependable study has a research process that is logical, traceable, and well documented. When readers can follow how the research was conducted from beginning to end, they are better equipped to assess the reliability and rigour of the study.

The degree to which qualitative research findings are believable, dependable, and accurately reflect the experiences and perspectives of participants
A researcher's conscious and continuous reflection on how their background, perspectives, and interactions with participants may affect the collection, analysis, and interpretation of data
The degree to which research is carefully designed, systematically conducted, transparently documented, and appropriately analyzed so that its findings can be trusted
Confidence that the findings reflect the reality and viewpoints of the participants rather than than the researcher's assumptions or biases
The extent to which the research process is logical, well-documented, and could be repeated in similar context with comparable results
The degree to which the findings are shaped by the participants and the data, not by researcher bias
The degree to which the findings can be transferred to or used in contexts similar to the one studied
