In systems engineering, dependability is a measure of a system's availability, reliability, and its maintainability, and maintenance support performance, and, in some cases, other characteristics such as durability, safety and security. In software engineering, dependability is the ability to provide services that can defensibly be trusted within a time-period. 2.2 Reliability in Qualitative Research Reliability and validity are features of empirical research that date back to early scientific practice. In qualitative research, researchers look for dependability that the results will be subject to change and instability rather than looking for reliability. The criteria used to test rigor in the convention, scientific paradigm are well known. There are four aspects of trustworthiness that qualitative researchers must establish: credibility, dependability, transferability, and confirmability. Reliability and validity should be taken into consideration by qualitative inquirers while designing a study, analyzing results, and judging the quality of the study, 30 but for too long, the criteria used for evaluating rigor are applied after a research is completed—a considerably wrong tactic. Each process in the study should be reported in detail to enable an external researcher to repeat the inquiry and achieve similar results. Credibility cannot be attained in the absence of dependability, just as validity in quantitative research cannot be achieved in the absence of reliability. Data trustworthiness has four key components: credibility, transferability, dependability, and … BMJ 2001;323:799–803. Slevin E. Enhancing the truthfulness, consistency, and transferability of a qualitative study: using a manifold of two approaches. Fraser S, Greenhalgh T. Coping with complexity: educating for capability. This also enables researchers to understand the methods and their effectiveness. Dependability ensures that the research findings are consistent and could be repeated. Qualitative research tends to assume that each researcher brings a unique perspective to the study. Qualitative research must be reflective, maintaining a sense of awareness and openness to the study and results. Reliability in qualitative studies is mostly a matter of “being thorough, careful and honest in carrying out the research” (Robson, 2002: 176). 7. There are a number of strategies for enhancing confirmability. Since we consistently get questions about issues of trustworthiness in qualitative research, we decided to do a four-part series that really goes in-depth about each aspect of trustworthiness and how it can be established. There are various ways in which the reliability of the research instrument can be enhanced although it is impossible to ascertain that you get a 100 percent reliable research instrument in a qualitative research. The use of reliability and validity are common in quantitative research and now it is reconsidered in the qualitative research paradigm. 1993 Apr;15(2):263-6. doi: 10.1177/019394599301500212. If you are talking about social research, you can’t: and those that suggest you can are misguided. Although reliability and validity are treated separately in quantitative studies, these terms are not viewed separately in qualitative research. 9. validity and reliability of research findings, qualitative researchers aim. 2. Each of the research approaches involve using one or more data collection methods.These are some of the most common qualitative methods: Observations: recording what you have seen, heard, or encountered in detailed field notes. This is the third standard for judging qualitative studies and refers to the stability or consistency of the inquiry processes used over time. Such strategies include: 1. The concept of confirmability is the qualitative investigator’s comparable concern to objectivity. To check the dependability of a qualitative study, one looks to see if the researcher has been careless or made mistakes in conceptualizing the study, collecting the data, interpreting the findings and reporting results. How to enhance the reliability in a qualitative research. Qualitative research allows a researcher to provide an interpretation of observed experiences and actions of individuals and groups in different contexts. Int J Qual Res 2002;1:1–19. Frameworks for ensuring trustworthiness and rigour of qualitative research have been in existence for many years (Shenton 2004). This article discusses the use of validity and reliability in the qualitative research paradigm. Qualitative content analysis is used mostly when the researcher wants to analyze qualitative data. Dependability - showing that the findings are consistent and could be repeated; Confirmability - a degree of neutraility or the extent to which the findings of a study are shaped by the respondents and not researcher bias, motivation, or interest. The researcher needs a self-critical attitude, taking into account how his or her preconceptions affect the research. There are various techniques for improving confirmability. In this topic, the first discussion is what about Morse, Barrett, Mayan, Olson, and Spiers have to say about validity and reliability as essential quantitative concepts and then a new conclusion will be provided (Silverman, 2004). This section describes the qualitative methods to assess the rigour of the qualitative study. Data accuracy and reliability are very important concerns in doing good research because inaccurate and unreliable data lead to spurious or wrong conclusions. In the audit, another researcher who is not connected to the study but has qualitative research experience examines the audit trail, including study findings and conclusions. Since reliability and validity are rooted in positivist perspective then they should be redefined for their use in a naturalistic approach. Qualitative research: the evaluation of its credibility, fittingness, and auditability West J Nurs Res. If, for some reason, you inadvertently input wrong data into the computer, output will still be produced. Qualitative researchers are not interested in causal laws but in people’s belief, experience and meaning systems from the perspective of the people. 2019 again: “Quantitative researchers have sometimes made the mistake of evaluating qualitative research reports using the standards of quantitative research, expecting IRR regardless of the nature of the qualitative research. Methodological rigour. establishing reliability validity in qualitative research. But of course, the results are erroneous because the data entered is faulty. Evaluating the intercoder reliability (ICR) of a coding frame is frequently recommended as good practice in qualitative analysis. Therefore, 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. 2 It lends itself to health services research in general and social pharmacy research in particular, where an in-depth understanding of the participants’ experiences is needed. A sequential, mixed-model research design was used, in which both qualitative and quantitative research methods were applied. The concept of reliability broadly describes the extent to which results are reproducible, for example, from one test to another or between two judges of behavior [29]. Confirmability This criterion is concerned with establishing that the data represent the information participants provided and that the interpretations of those data are not imagined by the inquirer. Confirmability in Qualitative Research means the degree to which the outcomes could be confirmed or corroborated by other people. Interviews: personally asking people questions in one-on-one conversations. Research DIMENSION Rigor or Reliability and Validity in Qualitative Research: Perspectives, Strategies, Reconceptualization, and Recommendations Brigitte S. Cypress, EdD, RN, CCRN Issues are still raised even now in the 21st century by the persistent concern with achieving rigor in qualitative research… the validity and reliability of a qualitative study. Confirmability refers to the degree to which the results could be confirmed or corroborated by others. Trustworthiness is the truth value. Qualitative research methods. Dependability. Accounting for personal biases which may have influenced findings; 6. MacDonald et al. Dependability refers to consisten-cy of the findings; it’s achieved through an external audit of the study. Confirmability occurs once credibility, transferability and dependability have been established. In qualitative research. ICR is a somewhat controversial topic in the qualitative research community, with some arguing that it is an inappropriate or unnecessary step within the goals of qualitative analysis. 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. Reliability is a concept that simply does not apply to qualitative social research. Trustworthiness of qualitative research, most of the time is questioned by positivists reason being that validity and reliability is not addressed like how it is done in naturalistic work. However, validity and reliability … RELIABILITY The term qualitative research is really an umbrella term representing a variety of research approaches which share certain common elements. 8. Answering this real need, qualitative researchers have proposed trustworthiness as the qualitative equivalent to reliability and validity in quantitative research. The trustworthiness of qualitative research is frequently interrogated by positivists, perhaps because their concepts of validity and reliability cannot be addressed in the same way in naturalistic study. This is measured by the standard of which the research is conducted, analysed and presented. Focus groups: asking questions and generating … Author C T Beck 1 Affiliation 1 University of Rhode Island, Kingston. Nurse Res 2002;7:79–197. to design and incorporate methodological strategies to ensure the ‘trustworthiness’ of the findings. Qualitative research is important because it measures things that numbers might not be able to define, qualitative methods sometimes identify trends before they show up in the quantitative data. The researcher can document the procedures for checking and rechecking the data throughout the study. Moreover, in qualitative research, the researcher is considered as the instrument and the reliability and validity of the research to a large extent dependent on the researcher’s own ability to immerse into the research.
