Quality in quantitative research: Reliability
• There is a need for reliability in quantitative research > reliability essentially looks at whether the same results can be achieved with different researches and on different populations.
○ The more replications you have, the more reliable the method is considered to be (this is linked to the replication crisis in psychology that a lot of classic, more modern studies are no longer replicable.)
○ The researcher should be able to be removed from the research process
- But the problem with using this in qualitative research is that we focus on individual meanings which can be understood in several different ways thus interpretations may not always replicate or match
Quality in quantitative research: Validity
• Validity looks to identify whether the researcher has measured what it intends to measure.
○ Different types of validity > e.g. internal (if the concept has been measured and not some additional variable > e.g. making sure depression measure is measuring depression + not anxiety)
• This would be an important means of assessing quality and quantitative research.
• However, the core problem with using this as a means to assess quality in qualitative research is that individual meanings can differ + qualitative data collection largely relies on semi-structured interview guides meaning that there is a lesser standard of standardisation.
- Qualitative research is also sensitive to the cultural context of participants, meaning that often other aspects are considered within the interpretation.
Quality in quantitative research: Generalisability
• Generalisability looks to establish the findings can be applied to other contexts outside of the research environment
• In quantitative research, the more generalisable the findings, the more that it can tell us about the phenomenon.
• However, problem w/ using this in qual research is mainly because qualitative research understands help us participant accounts which are contextually and historically bound. > There is little scope for findings, then, to apply readily outside the research context.
- Focus is on the detail of the phenomena
Quality in qualitative research (Yardley, 2008)
Sensitivity
- Because qualitative and quantitative methods are different. They tell us different things + explore issues in different ways > would be inappropriate to expect the same standards of quality to be applied to.
• Qualitative research needs to be sensitive to the context in which it is being produced and to the accounts of participants + ensure that they are being reported on in a sensitive way without misleading.
• We also need to ensure that we act as ethical practitioners and ensure that participants are aware of the true nature of the study and their rights as participants. - An inductive approach is needed for data interpretation
Quality in qualitative research (Yardley, 2008)
Commitment and rigour
• We also need to appropriately report on the accounts of participants in a faithful way without misrepresenting their voices.
• The data collection also needs to be appropriate to the study.
• So, for example, if you’re interested in exploring personal experiences of sexual assault, perhaps the focus group may not be the best place to explore participant accounts
• Also need to make sure that the analytic technique is appropriate to the types of questions you want answered and that the process is conducted in a competent way.
- There needs to be a clear engagement with an understanding of the topic
Quality in qualitative research (Yardley, 2008) Transparency
• process of interpretation needs to be clear on the analytic process and decision making needs to be retained clear and explicit discussion in the process > this is to account for the particular way that you do your analysis.
• The quote selected need to be appropriate means that they match the point and the interpretation being outlined in the analysis.
- There needs to be a clear discussion of how data fits with the research question and an embedding and addressing of any points of reflexivity.
Quality in qualitative research (Yardley, 2008)
Impact
- This is where qualitative researchers need to think about the impact that they have had on those around them and in the field of study
- In applied settings, the needs to be a consideration of how these insights can help address and improve current practises and in theoretical considerations.
- In theoretical considerations, need to think about how these results push theory forward
- Are there issues that could be taken away from this research that have a lasting impact on others lives or inform future work that may lead to this?
- Research as a political act is usually done for a purpose (whether it’s genuine interest in the topic and wanting to bring about change) > the impact of research stretches beyond the person who’s conducting it and there needs to be a consideration as to whether the research would likely be used politically to help, but also to hinder populations.
Addressing quality (Cresswell & Miller, 2001) Triangulation
• Can be done in two ways > methodological or researcher
• Methodological triangulation: use different data collection methods or analytic techniques to improve the quality of the insights you can achieve about a phenomenon or population.
○ Consistency in themes > greater trustworthiness of findings
• Researcher triangulation: where multiple researchers would analyse the same dataset in the hopes of getting a high rate of agreement between two or more researchers.
○ Consistency in themes > greater trustworthiness of findings
- There are problems with this however > if you’re more inclined towards critical method, then this can actually measure some of the sentiment of reliability as a marker of quality and may not address the importance of researcher interpretation, especially when using more critical methods or looking at the latent level of themes.
Addressing quality (Cresswell & Miller, 2001) Audit trail
• This is the process of producing a clear overview of the research decisions made > e.g. field notes
• Field notes involve taking notes after the interviews/focus groups + identifying issues you felt were particularly pertinent to the participants > e.g. commenting in how the interview went etc…
• Also need a clear + evidenced analytic process
• Audit trail: the process of providing a clear account of your procedure, analytic process and any decisions made > e.g. why you used semi-structured interviews, why it matters for your topic, what will it contribute?
• Deviant cases: not all data will fit together on systematically, there will be cases that don’t fit and don’t make sense. And there needs to be an appreciation of these what we call deviant cases.
May perhaps offer an alternative account of experiences or perceptions.
Addressing quality (Cresswell & Miller, 2001) Reflexive practice
• need to ensure that you have provided a clear discussion of the reflexive processes of doing research, and you need to be thinking about whether or not the design was well considered and justified
• Example of reflexive practice include considering: are concepts meaningful? Are the methods appropriate?
○ have you analysed your data carefully, faithfully and well?
○ are your conclusions while supported and are they applicable?
- Reflexivity happens throughout the research process + also think about what you’ve brought to the research as well other assumptions that you had of the topic the population or have you also learnt something about the topic + population, thinking about how it’s changed us as researchers
Addressing quality (Cresswell & Miller, 2001) Collaboration
• This is where the voices of participants and other experts are used to develop the research insights.
○ for example, some researchers will ask participants to check their transcripts or themes to make sure that they are happy that the researcher has been faithful to their voice
○ this could lead to censoring of the participants voice > they may not like some of the interpretation and ask for it to not be included.
○ this could have ramifications for the quality of the final product, but also it may further allow participants to be happy with their contribution
• researchers may also call on experts in the fields, such as practitioners, to help and understand and work through data.
Critiques: Lacking objectivity
The critique
• Qualitative research is critiqued for lacking objectivity
○ Objectivity is associated with limited researcher-influence
○ Objectivity is considered to be a marker of ‘good’ scientific enquiry
• Thus suggesting qualitative research sits outside of good scientific enquiry
• This may be evidence of social constructionism in action > objectivity = truth, fact, neutrality, and reality
• Whereas subjectivity = tentative, less-than-real, biased, non-useable things in psychology
• qualitative research is subjective in nature and therefore biased and unhelpful in telling us things about human experience according to the notions of objectivity.
The response
• In qualitative research the methods are subjective but this is never denied but rather embraced.
• Subjectivity is acknowledging and exploring the interwoven role of the researcher, the studied, and the socio-historical-political context in the research process
• Subjectivity is an accepted aspect of qualitative research
○ It is not seen as a limitation
○ It is an acceptable and essential aspect of qualitative research
Addressed through methodology & reflexivity which acknowledge the personal subjectivities of the researcher
Critiques: Lacking generalisability
• Importantly, research is always limited. It can never be truly generalisable across all populations, cultures and situations > there are natural limits to the applicability of the research.
• E.g. a study looking at conscientiousness in final year students may not relate to the rest of the student population
• Instead, it is about thinking about how a body of evidence can build up a picture of the phenomenon over time > So using qualitative methods, we can add to that growing body of evidence.
• Even if a qual study is not generalisable (even in quantitative), instead, we can think about the weight of evidence and what the weight of evidence is telling us about phenomenon in populations.
- We also need to think about the idea of science as something that is continual progression and is not necessarily about reaching “the answer”, is about reaching an answer that provides an insights and offers of opportunities for development.
Critiques: Sample size
- Sample sizes in qualitative research tend to be smaller than in quantitative research
- The criticism levied at qualitative research is primarily focused on the notion of generalised ability and reliability. The more data a researcher collects, the more reliable the data tends to be, and the more generalisable it is therefore likely to be in qualitative research
- There needs to be an adequate and detailed justification for sample sizes
- However, developing a justification for sample sizes is often difficult and an unwieldy task for researchers to explain and justify
When to stop data collection
Saturation
• Movement by researchers to use an ocean of saturation
• Saturation is concerned with stopping data collection based on the premise that no new ideas were being generated > themes were saturated
• some researchers went so far as to provide numerical or statistical explanations for why and when projects projects would stop recruited based on expectations, when data would be saturated
• This is a highly criticised concept and not aligned to more critical approaches in qualitative research. This premise moves quite strongly towards statistical remits of knowledge, and some would say that the concept of saturation is inappropriate for qualitative research.
• Saturation focus on no new insights being developed.
○ Vague and impractical (O’Reiley & Parker, 2012) > no guidance for researchers
○ Not consistent with critical qualitative approaches (Braun & Clarke, 2019) > assumes we can know something absolutely about data (data exists + is up to us to remove it)
Fails to address issues like diversity, theoretical context, and specific qualities of the study (Sim, Saunders, Waterfield, & Kingstone, 2018)
