Mechanisms to increase the reliability and validity of qualitative research Ultimately, improve research rigor and usefulness Verification strategies. In current-day practice, qualitative approaches are once again gaining considerable momentum as useful methods for building knowledge in social work and other allied helping professions (Finlay & Ballinger, 2006; Padgett, 2008; Pope & Mays, 2006). Accordingly, qualitative research has a more difficult task when trying to establish the reliability and validity of its data. They also assure readers that the findings of the study are credible and trustworthy. Abstract. A similar exploration of validity and proposed alternatives follows. The reason why they are discussed in a chapter of their own is to provide a better understanding of what their role was in this study. Due to this, methodology, methods and results naturally differ accordingly (Goertz & Mahoney, 2012). Qualitative Validity. The use of reliability and validity are common in quantitative research and now it is reconsidered in the qualitative research paradigm. 21 The nature and purpose of the quantitative and qualitative traditions are also different that it is erroneous to apply the same criteria of worthiness or merit. The concept of reliability is then analysed, establishing the traditional understanding of the term, and evaluating alternative terms. Noble, H., Smith, J.

Validity in qualitative research: Application of afeguards. Evidence Based Nursing, 18, (2): 34-35. Evaluating the quality of research is essential if findings are to be utilised in practice and incorporated into care delivery. There are particular steps to take when attempting internal validity, test -retest reliability, etc. 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. This article discusses the use of reliability and validity in the qualitative research paradigm specifically in case study method. Author content. Determine whether you are going to use interviewing or observation as your data recording technique. Validity and reliability as quality indicators have an uneasy standing in qualitative research and are subject to numerous debates. It is also through this association that the way to achieve validity and reliability of a research get affected from the qualitative researchers’ perspectives which are to eliminate bias and increase the researcher’s truthfulness of a proposition about some social phenomenon using triangulation. That is, they mean different things to different researchers. Verification processes ensure congruence (alignment) among the research questions, published literature, participants, data collection, and analysis Design Implementation Dissemination Methodological coherence = Congruence. The reliability and validity of your results depends on creating a strong research design, choosing appropriate methods and samples, and conducting the research carefully and consistently. Quantitative and qualitative research is based on different research paradigms that reflect the researcher’s scientific worldview. In this chapter validity and reliability are discussed.

The rejection of reliability and validity in qualitative inquiry in the 1980s has resulted in an interesting shift for “ensuring rigor” from the investigator's actions during the course of the research, to the reader or consumer of qualitative inquiry. Meticulous attention to these two aspects can make the difference between good research and poor research and can help to assure that fellow scientists … When handled meticulously, the reliability and validity parameters help differentiate between good and bad research. Reliability and Validity in Qualitative Research 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. Quantitative research is the process of a systematic investigation, primarily using numerical techniques (statistical, mathematical or computational), to test hypothetical generalisations. Instrument: A valid instrument is always reliable. Qualitative Research. Techniques used to establish reliability and validity in quantitative research are clear and well-established. ity and validity in qualitative research is such a different process that quantitative labels should not be used. For all secondary data, a detailed assessment of reliability and validity involve an appraisal of methods used to collect data [Saunders et al., 2009].

Establishing validity and reliability in qualitative research can be less precise, though participant/member checks, peer evaluation (another researcher checks the researcher’s inferences based on the instrument (Denzin & Lincoln, 2005), and multiple methods (keyword: triangulation), are convincingly used. 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. The roles of reliability and validity as used in qualitative research designs has been subjected to disagreement by different researchers. Understanding Reliability and Validity in Qualitative Research Reliability in qualitative studies is mostly a matter of “being thorough, careful and honest in carrying out the research” (Robson, 2002: 176). The reliability and validity of the research tool can also be enhanced by using different techniques to collect data are used to get in depth and reliable results. So being able to critique quantitative research is an important skill for nurses. How to make sure (or provide evidence) that our study is valid and reliable? how validity and reliability are achieved in quantitative research? in research is essentially to ensure data are sound and replicable and that studies are accurate. In order to appreciate the quality of academic research, it makes sense to apply different criteria for (1) quantitative and (2) qualitative methods. Validity Reliability; Meaning: Validity implies the extent to which the research instrument measures, what it is intended to measure. Validity and reliability increase transparency, and decrease opportunities to insert researcher bias in qualitative research [Singh, 2014]. Reliability and validity are analogues and are determined differently than in quantitative inquiry. VALIDITY AND RELIABILITY IN QUALITATIVE RESEARCH H.I.L. trustworthiness.
