Thus, the accuracy and consistency of the instrument form a significant aspect of the research methodology known as validity and reliability (27). Download Full PDF Package. The value of instrument reliability ⦠And, in general, checking for validity of an instrument is more difficult than checking for reliability because validity is measuring data related to knowledge whereas reliability only concerns with the consistency of scores. Accordingly, qualitative research has a more difficult task when trying to establish the reliability and validity of its data. study method. However, validity is better evidenced in quantitative studies than in qualitative research studies. A CRITERION FOR ASSESSING RELIABILITY Compared to validity, reliability is more easily assessed. the validity and reliability of quantitative research cannot be applied to qualitative research, there are ongoing debates about whether terms such as validity, reliability and generalisability are appropriate to evalu-ate qualitative research.2â4 In the broadest context these terms are applicable, with validity referring to the integ- Evaluating the quality of research is essential if findings are to be utilised in practice and incorporated into care delivery. Reliability and Validity in Qualitative Research [Page 273] It is important for qualitative studies to emulate the scientific method in striving for empirical groundedness, generalizability, and minimization of bias (Hammersly, 1992). It is critical to understand rigor in research. xref However, since it cannot be quantified, the question on its correctness is critical. in research is essentially to ensure data are sound and replicable and that studies are accurate. Techniques used to establish reliability and validity in quantitative research are clear and well-established. Guba2 (1981), Guba and Lincoln3 (1982), and Lincoln and Guba1 (1985) refer to trustworthiness as something that evolved from 4 major concerns that relate to it in %%EOF 2190 0 obj <>/Filter/FlateDecode/ID[<1C8D369C3C51574FA954BE063D2A7018>]/Index[2143 64]/Info 2142 0 R/Length 191/Prev 1444916/Root 2144 0 R/Size 2207/Type/XRef/W[1 3 1]>>stream The rejection of reliability and validity in qualitative inquiry in the 1980s has resulted in an interesting shift for "ensuring rigor" from the investigatorâs actions during the course of the research, to the reader or consumer of qualitative inquiry.

Are the research questions clear and are the features of the study design similar to them? reliability, validity and triangulation, if they are relevant research concepts, particularly from a qualitative point of view, have to be redefined in order to reflect the multiple ways of establishing truth.

Instrument: A valid instrument is always reliable. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure. Establishing validity and reliability in qualitative research can be less precise, though participant/member checks, peer evaluation (another researcher checks the researcherâs inferences based on the instrument (Denzin & Lincoln, 2005), and multiple methods (keyword: triangulation), are convincingly used. The use of reliability and validity are common in quantitative research and now it is reconsidered in the qualitative research paradigm.
