In general practice, qualitative research contributes as significantly as quantitative research, in particular regarding psycho-social aspects of patient-care, health services provision, policy setting, and health administrations. In contrast to quantitative research, qualitative research as a whole has been constantly critiqued, if not disparaged, by the lack of consensus for assessing its quality and robustness. This article illustrates with five published studies how qualitative research can impact and reshape the discipline of primary care, spiraling out from clinic-based health screening to community-based disease monitoring, evaluation of out-of-hours triage services to provincial psychiatric care pathways model and finally, national legislation of core measures for children's healthcare insurance. Fundamental concepts of validity, reliability, and generalizability as applicable to qualitative research are then addressed with an update on the current views and controversies. Br J Gen Pract ;e
Issues of validity and reliability in qualitative research
Things are slightly different, however, in Qualitative research. Breakwell, ; Cohen et al. What seems more relevant when discussing qualitative studies is their validity , which very often is being addressed with regard to three common threats to validity in qualitative studies, namely researcher bias , reactivity and respondent bias Lincoln and Guba, It may be granted, for example, by the duration of the study, or by the researcher belonging to the studied community e.
Being a member of this community, or even being a friend to your participants see my blog post on the ethics of researching friends , may be a great advantage and a factor that both increases the level of trust between you, the researcher, and the participants and the possible threats of reactivity and respondent bias.
Peer debriefing and support is really an element of your student experience at the university throughout the process of the study.
Various opportunities to present and discuss your research at its different stages, either at internally organised events at your university e.
These events are invaluable in helping you to asses the study from a more objective, and critical, perspective and to recognise and address its limitations. This input, thus, from other people helps to reduce the researcher bias. Member checking , or testing the emerging findings with the research participants, in order to increase the validity of the findings, may take various forms in your study. It may involve, for example, regular contact with the participants throughout the period of the data collection and analysis and verifying certain interpretations and themes resulting from the analysis of the data Curtin and Fossey, Finally, member checking, in its most commonly adopted form, may be carried out by sending the interview transcripts to the participants and asking them to read them and provide any necessary comments or corrections Carlson, Whenever an emerging explanation of a given phenomenon you are investigating does nto seem applicable to one, or a small number, of the participants, you should try to carry out a new line of analysis aimed at understanding the source of this discrepancy.
If you adopt the above strategies skilfully, you are likely to minimize threats to validity of your study. Breakwell, G. In Breakwell, G. Research Methods in Psychology. London: Sage. Buchbinder, E.

I have come to see reliability and validity more as a defence of is the research rigorous, thorough and careful therefore is it morally, ethically and accurately defensible? Hi Nathan, thank you for your comment. I have read your blog article and really liked it — would you mind if I shared it on my Facebook page, and linked to it from my blog section on this page?
Are you on twitter? I do have Facebook, feel free to find me there. I also started to follow your blog so that I am notified about your content. I agree with what you said here and in your posts, and I like the topic of your blog.
This is definitely something that we should pay more attention to when doing research. It would be interesting to talk some time and exchange opinions, as our research interests seem very closely related. Have a good day!

Show all documents Investigation of validity and reliability works in postgraduate mathematics theses that adopt qualitative research in Turkey: Functions of data collection tool Abstract. In this research , master and doctorate thesis which adopts qualitative method in mathematics education studies in Turkey are thoroughly inspected in terms of their validity and reliability , thus the research has a case study as a research model. From Thesis Web site by Council of Higher Education, master thesis which are published and contains both primary and secondary mathematical studies and 27 doctorate thesis are analysed by using document analysis technique and data is resolved by means of content analysis. It was seen in almost more than half of these theses in which reliability and validity are done, that in addition to the credibility, transmissibility, consistency and confirmability strategies that is used for qualitative paradigm, Statistical calculations are also used in regards of quantitative paradigm.

Reliability is a concept that refers to producing consistent results time after time. If you commission a qualitative research or evaluation project, how can you be sure it is reliable? If a qualitative research project is reliable, it will help you understand a situation clearly that would otherwise be confusing. Qualitative research is about discussion, about delving into topics in depth, getting beneath the surface. However, clients would not commission qualitative studies if there was no sense that the results would be reliable, that they could make confident decisions based on the results.
Validity and reliability are key aspects of all research. This is particularly vital in qualitative work, where the researcher's subjectivity can so readily cloud the interpretation of the data, and where research findings are often questioned or viewed with scepticism by the scientific community.
Validity, reliability, and generalizability in qualitative research
Depending on their philosophical perspectives , some qualitative researchers reject the framework of validity that is commonly accepted in more quantitative research in the social sciences. They reject the basic realist assumption that their is a reality external to our perception of it. These qualitative researchers argue for different standards for judging the quality of research. For instance, Guba and Lincoln proposed four criteria for judging the soundness of qualitative research and explicitly offered these as an alternative to more traditional quantitatively-oriented criteria.
The reliability of qualitative research
What are the Criteria for Inferring Causality? How do we assess reliability and validity? Reliability in qualitative research refers to the stability of responses to multiple coders of data sets. It can be enhanced by detailed field notes by using recording devices and by transcribing the digital files. However, validity in qualitative research might have different terms than in quantitative research. Trustworthiness is achieved by credibility, authenticity, transferability, dependability, and confirmability in qualitative research. To operationalize these terms, long engagement in the field and the triangulation of data sources, methods, and investigators to establish credibility.
Нам нужны указания. ГЛАВА 114 - Обыщите их еще раз! - потребовал директор. В отчаянии он наблюдал за тем, как расплывчатые фигуры агентов обыскивают бездыханные тела в поисках листка бумаги с беспорядочным набором букв и цифр. - О мой Бог! - Лицо Джаббы мертвенно побледнело. - Они ничего не найдут. Мы погибли. - Теряем фильтры Протокола! - раздался чей-то голос.
