Validity, reliability, and generalizability in qualitative research

Harvard Educational Review 1 September ; 62 3 : — Qualitative researchers rely — implicitly or explicitly — on a variety of understandings and corresponding types of validity in the process of describing, interpreting,and explaining phenomena of interest. In this article, Joseph Maxwell makes explicit this process by defining five types of understanding and validity commonly used in qualitative research.

After discussing the nature of validity in qualitative research,the author details the philosophical and practical dimensions of: descriptive validity,interpretive validity, theoretical validity, generalizability, and evaluative validity. In each case, he addresses corresponding issues of understanding. In conclusion,Maxwell discusses the implications of the proposed typology as a useful checklist of the kinds of threats to validity that one needs to consider and as a framework for thinking about the nature of these threats and the possible ways that specific threats might be addressed.

How To Determine Validity in Qualitative Research

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. The essence of qualitative research is to make sense of and recognize patterns among words in order to build up a meaningful picture without compromising its richness and dimensionality. Unlike quantitative research which deals primarily with numerical data and their statistical interpretations under a reductionist, logical and strictly objective paradigm, qualitative research handles nonnumerical information and their phenomenological interpretation, which inextricably tie in with human senses and subjectivity. While human emotions and perspectives from both subjects and researchers are considered undesirable biases confounding results in quantitative research, the same elements are considered essential and inevitable, if not treasurable, in qualitative research as they invariable add extra dimensions and colors to enrich the corpus of findings.

Validity relates to the appropriateness of any research value, tools and techniques, and processes, including data collection and validation Mohamad et al. These eight validation strategies are not in order of importance.


Instead, terminology that encompasses both, such as credibility, transferability, and trustworthiness is used. To understand the meaning of reliability and validity, it is necessary to present the various definitions of reliability and validity given by many qualitative researchers from different perspectives.


How is reliability and validity realized in qualitative research?

Like many concepts in the social sciences, there are referred to as contested terms. Validity and reliability as quality indicators have an uneasy standing in qualitative research and are subject to numerous debates. Validity, evaluation research, validity checklist, reliability, policy research Introduction Since the days of ethnographic pioneers such as the Anthro- pologist Franz Boas and members of the Chicago School of Urban Sociology, a vast literature has developed on the proce-dures and underlying philosophies of qualitative research.

Skip to search form Skip to main content You are currently offline. Some features of the site may not work correctly. The use of reliability and validity are common in quantitative research and now it is reconsidered in the qualitative research paradigm.

It aims at understanding the concept, illuminating reality, and extrapolation of the situation to other similar situations, rather than effect predictions, generalize, or make causal determination. All research requires validity and reliability. Validity shows the soundness of the research methodology and the results generated, based on the extent to which the research remains in congruity with universal laws, objectivity, truth, and facts. The validity of statistics driven quantitative research depends on the soundness the instrument adopted. Validity in qualitative research however depends on the ability and effort of the researcher, as the researcher is the instrument. Credibility refers to believability or reasonableness. Credibility as an element of validity of qualitative research denotes the extent to which the research approach and findings remain in sync with generally accepted natural laws and phenomenon, standards, and observations.

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.

Nature of Qualitative Research versus Quantitative Research

Published on July 3, by Fiona Middleton. Revised on June 26, Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method , technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.

 Извините, что я вас побеспокоил, но скажите: вы, случайно, не были сегодня на площади Испании.

 Если Танкадо перестанет быть фактором? - вслух размышлял Нуматака.  - Тогда мы с вами придем к соглашению. - Буду держать вас в курсе, - произнес голос, и вслед за этим в трубке раздались короткие гудки. ГЛАВА 14 Беккер впился глазами в труп.

 Не стану вас затруднять, - ухмыльнулась она, - благодарю за предложение. Но все же кто. Беккер держался своей легенды: - Я из севильской полиции. Росио угрожающе приблизилась. - Я знаю всех полицейских в этом городе.

Я видел его в Интернете. Мои люди несколько дней пытаются его взломать. - Это зашифрованный вирус, болван; ваше счастье, что вам не удалось его вскрыть. - Но… - Сделка отменяется! - крикнул Стратмор.
