Reliability assessment of observation data: A possible methodological problem. “If the information produced by observing is to be of any long-term or general use, it has to be repeatable information; in other words, it has to be information that would be obtained by any one else attempting to make the same observations” (Saslow, 1982, p. 10). Yin (2009) proposed three (3) principles of data collection to deal with the problems of establishing the construct validity and reliability of the case study evidence which are; … “Sampling, Reliability and Validity in Qualitative Research” Introduction Qualitative research is a way of finding solution, exploration for a problem in a society in a systematical way. The insights garnered here will move novice researchers and doctoral students to a better conceptual grasp of the complexity of reliability and validity and its ramifications for qualitative inquiry. USA.gov. Accordingly, qualitative research has a more difficult task when trying to establish the reliability and validity of its data. Generally speaking, recording by highly trained observers is more reliable than recording by poorly trained or untrained observers, observers operate more consistently if they know that their accuracy is going to be regularly checked than if no accuracy checks are implemented, recording by outside observers is more reliable than recording by the participants themselves, simple coding schemes with well defined categories can be applied more reliably than complex coding schemes or coding schemes with poorly defined categories, and so on (Cooper, Heron & Heward, 1987; Johnson & Bolstad, 1973; Kazdin, 1977; Reid, 1970). TECKS. Rigor in qualitative research: the assessment of trustworthiness. The first question which may be asked of the data collected during the course of a research investigation is the question “Did the observation procedure operate in a consistent fashion from one occasion to the next?”. Beverly Hills: Sage Publications. An interesting result of a qualitative research: Academic exhaustion barrier to professionalism in medical students. 2004 Nov;48(4):388-96. doi: 10.1111/j.1365-2648.2004.03207.x. (1982). Multiple strategies can be used to ensure validity in qualitative research, such as triangulation, member checking, rich description, prolonged time in the field, and use of external auditors (Creswell, 2014; Creswell & Poth, 2018). Health SA. What standards are used when assessing the believability of reports of learning, Accuracy, threats to accuracy and the assessment of accuracy, Measurement validity, threats to validity and the assessment of validity. A note on percentage of agreement. Am J Occup Ther. The test is administered to a sample of learners, the items in the test are divided into two halves (e.g. NLM Understanding Young People and Their Care Providers' Perceptions and Experiences of Integrated Care Within a Tertiary Paediatric Hospital Setting, Using Interpretive Phenomenological Analysis. Kazdin, A. E. (1977). Strictly speaking this procedure does not provide a measure of the reliability of either of the observers (because only one record of the same events is obtained from each observer) and it does not provide a measure of the accuracy of the data obtained by the primary observer (because the accuracy of the second observer is also unknown). Interobserver agreement data provide important information regarding data quality in situations where neither reliability nor accuracy can be assessed but a measure of interobserver agreement is not a measure of either reliability or accuracy (Johnston & Pennypacker, 1993). odd numbered items and even numbered items), and the degree of correlation between the scores on the two sets of items is calculated. New York: Pergamon. Mirmoghtadaie Z, Ahmady S, Kohan N, Rakhshani T. J Educ Health Promot. Cooper, J. O., Heron, T. E., & Heward, W. L. (1987). In order to assess the reliability of a data collection procedure, that procedure must be applied to the same events on more than one occasion and the degree of identity between the two separate records assessed. Rigor or rigor mortis: the problem of rigor in qualitative research revisited. Reliability issues often come up when researchers adopt a subjective approach to research (Wilson, 2010), which on the other hand is consciously allowed in qualitative research. If your method has reliability… Critical Analysis of Strategies for Determining Rigor in Qualitative Inquiry. Understanding Reliability and Validity in Qualitative Research. The conditions upon which learning depends, Teacher Education’s Core Knowledge and Skills. In this article, I have discussed about the threats to reliability in qualitative research and measures to enhance reliability. Belmont, CA: Wadsworth. In educational research, the extent to which an observation or measurement procedure has been operated in a consistent fashion is referred to as its reliability. Strictly speaking this procedure does not provide a measure of test reliability because each learner completes each item only once. Copyright © This text describes objectivity in qualitative research by focusing on the issues of validity and reliability in terms of their limitations and applicability in the social and natural sciences. Beliefs about the nature of reality and what can be observed. 2. What, exactly, is observed by the three main approaches to research? This can be due to many factors including poor question wording, bad instrument design or layout, illegibility of field notes, and so on. In studies where you are evaluating a program you can introduce noise through poor reliability of treatment implementation. Frameworks for ensuring trustworthiness and rigour of qualitative research have been in existence for many years (Shenton 2004). Test reliability may also be compromised in many ways: by tests which are too difficult, by ambiguously worded test questions, by test items which allow guessing, by tests which are too long, by inadequate test administration instructions, by changes in the testing conditions, by changes in motivation on the part of those completing the test, by inadequate marking guides, by failure to provide adequate training for test markers, and so on. She also had interest in different topics to research including teleworking, organization attractiveness, and old-age workers.  |  University of Toronto, Toronto, Ontario, Canada . Verification strategies for establishing reliability validity in qualitative research. New York: Macmillan Publishing Co. Johnson, S. M., & Bolstad, O. D. (1973). Reliability shows how trustworthy is the score of the test. The measures of correspondence which are most commonly calculated and reported are either the percentage of inter-occasion agreement or else the degree of inter-occasion correlation. New York: Random House. A synthesis of the historical development of validity criteria evident in the literature during the years is explored. However, to refresh your memory and ensure that we all attach the same meaning to validity, reliability and qualitative research… Reliability refers to the consistency of the measurement. Since reliability and validity Whereas quantitative researchers uses methods and designs to address threats to validity in advance of the research, qualitative researchers “must try to rule out most validity threats after the research has begun, using evidence collected during the research itself to make these alternative hypotheses implausible” (Maxwell, 1996, p. 88). How is learning to be observed and recorded? & Niwa, S. (1985). In order to calculate the reliability of a test, it is necessary to administer the same test to the same learner(s) on more than one occasion and to compare the scores obtained by each learner on each of the several administrations of the test. - 2021 Assessing the reliability of a test is a relatively simply matter. Threats to measurement reliability. There is … Issues are still raised even now in the 21st century by the persistent concern with achieving rigor in qualitative research. These preconceptions might have included factors such as: (a) the gymnast’s previous performance or track record (halo effect); (b) the gymnast’s nationality; and (c) the gymnast’s style, just to name a few. Hillsdale, NJ: Lawrence Erlbaum Associates. Introduction to measurement theory. Methodological issues in naturalistic observation: Some problems and solutions for field research. John Church, PhD, School of Educational Studies and Human Development. 7-67). Nahid Golafshani . sociology, medicine, business & economics, psychology, anthropology) (Huberman & Miles, 2002). Barlow, D. H., & Hersen, M. (1984). If the collected data shows the same results after being tested using various methods and sample groups, the information is reliable. Research workers should record interviews accurately and completely. c) Reliability. In L. A. Hamerlynck, L. C. Handy, & E. J. Mash (Eds. Threats to construct validity can arise from the choice of treatment (the operationalization of the IV, and the administration of the treatment), the choice of oucome measure (the operationalization of the DV, and the administration of the measurement). For example, a survey designed to explore depression but which actually measures anxiety would not be considered valid.

A note on the split-half method of calculating test “reliability”. Definition. 2020 Aug 18;8(1):96-103. doi: 10.1002/nop2.607. In educational research, the extent to which an observation or measurement procedure has been operated in a consistent fashion is referred to as its reliability. Controversies generalizability primary care research Clipboard, Search History, and several other advanced features are temporarily unavailable. Keywords. One common procedure which is used to assess the “reliability” of the observations made by an observer (or the classifications made by a coder) is to arrange for two separate observers (or coders) to make parallel and independent records of the same events. Identify and explain threats to credibility, dependability, confirmability, and transferability. Descriptive validity : What a person is unable to record while gathering data often is as significant as what is collected. All rights reserved. This site needs JavaScript to work properly. The measuring instrument in qualitative research consists of an individual without the support of standard instruments or baseline criteria. Fundamental concepts of validity, reliability, and generalizability as applicable to qualitative research are then addressed with an update on the current views and controversies. Please enable it to take advantage of the complete set of features! They provide some information regarding data quality because it is unlikely that high degrees of agreement could be obtained unless both observers were operating in a reliable (consistent) fashion. Epub 2015 Jul 16. Rural Homecare Nurses' Challenges in Providing Seamless Patient Care in Rural Japan. Qualitative Research Determine whether you are going to use interviewing or observation as your data recording technique. Develop a qualitative research plan for a topic and research question applicable to a specific field of specialization. Champaign, IL: Research Press. [Reconsidering evaluation criteria regarding health care research: toward an integrative framework of quantitative and qualitative criteria]. qualitative research also states that reliability is a consequence of the validity in a study.  |  Int J Qual Res, 1, pp.1–19. The trustworthiness of qualitative research generally is often questioned by posi-tivists, perhaps because their concepts of validity and reliability cannot be addressed in the same way in naturalistic work. 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 researcher then calculates the degree of inter-observer agreement (or inter-coder agreement) between the two independently obtained records. Validity. eCollection 2020. 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). Which approaches to research are collecting the most believable data on learning? Englewood Cliffs, NJ: Prentice Hall. 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, 1985). Qual Health Res. Prepared by Recommendations are made for use of the term rigor instead of trustworthiness and the reconceptualization and renewed use of the concept of reliability and validity in qualitative research, that strategies for ensuring rigor must be built into the qualitative research process rather than evaluated only after the inquiry, and that qualitative researchers and students alike must be proactive and take responsibility in ensuring the rigor of a research study. Research methodology is judged for rigor and strength based on validity, and reliability of a research [Morris & Burkett, 2011]. (Some qualitative researchers use the term dependability.) Modern educational measurement. Generally speaking, tests are more likely to function reliably if they consist of items which test a single skill or a small collection of well defined skills, use a number of items to assess each specific skill or understanding, consist of well written questions and items which discourage guessing, and are administered and marked by well trained personnel who have been provided with clear test administration guidelines and clear marking instructions (Allen & Yen, 1979; Popham, 1981). Research methodology provides us the principles for organizing, planning, designing and conducting a good research. Both of these measures are measures of the extent to which the two records of the same performance match each other. This article presents the concept of rigor in qualitative research using a phenomenological study as an exemplar to further illustrate the process. How are the effects of teaching on learning to be measured? The concept of reliability in qualitative research needs to be studied keeping in mind the interpretivist or naturalist paradigm of the research. She also served as Human research Manager in a large hospital in private sector. B. 1991 Mar;45(3):214-22. doi: 10.5014/ajot.45.3.214. Adolescent mothers' lived experiences whilst providing continuous kangaroo mother care: A qualitative study. This means that the reliability of an observational (or coding) procedure using human observers (or coders) can only be assessed if a sample of the behaviours of interest can be preserved in some way - as a written product, audio recording, or video recording, for example. The basic measure of recorder reliability, coder reliability, and test-retest reliability is the degree of correspondence or identity between independently obtained records (or codes) of the same behaviour, test performance, or self-report.
