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). Since reliability and validity How are the effects of teaching on learning to be measured? Reliability and validity in qualitative research. COVID-19 is an emerging, rapidly evolving situation. She also served as Human research Manager in a large hospital in private sector. This article presents the concept of rigor in qualitative research using a phenomenological study as an exemplar to further illustrate the process. Copyright © Strategies and tactics of behavioral research (2nd ed.). If the reliability of a direct observation procedure was being assessed by getting two observers each to independently code a videotaped sample of classroom interactions using a complex 15 category code, then something better than 80 per cent agreement between the observers might be accepted by readers as demonstrating an adequate degree of coder reliability (Barlow & Hersen, 1984). Champaign, IL: Research Press. Reliability assessment of observation data: A possible methodological problem. 2020 Aug 18;8(1):96-103. doi: 10.1002/nop2.607. Krakower, J. The concept of reliability in qualitative research needs to be studied keeping in mind the interpretivist or naturalist paradigm of the research. She also had interest in different topics to research including teleworking, organization attractiveness, and old-age workers. Understanding Reliability and Validity in Qualitative Research. Qual Health Res. Reliability, threats to reliability and the assessment of reliability, Approaches to research into learning and teaching. Child Development, 41, 1143-1150. The judges and the crowd both had preconceived notions about the gymnast. This site needs JavaScript to work properly. 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; ⦠(Some qualitative researchers use the term dependability.) Epub 2015 Jul 16. 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. 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). These preconceptions might have included factors such as: (a) the gymnastâs previous performance or track record (halo effect); (b) the gymnastâs nationality; and (c) the gymnastâs style, just to name a few. Foundations of behavioral research: Educational and psychological inquiry. 1993 Dec;16(2):1-8. doi: 10.1097/00012272-199312000-00002. Int J Environ Res Public Health. eCollection 2020. | Keywords. Please enable it to take advantage of the complete set of features! TECKS. 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. 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. Identify how to address a researchers pre-understanding, preconceptions, and biases about the research topic. A test which generates the same score when it is completed by the same individual on several occasions (without any intervening learning) is referred to as a reliable test and a coding procedure which generates the same count of behaviour when it is applied to the same videotape of learner performance on several separate occasions is said to be a reliable coding procedure (Johnston & Pennypacker, 1993; Kerlinger, 1964).

Prepared by Understanding Young People and Their Care Providers' Perceptions and Experiences of Integrated Care Within a Tertiary Paediatric Hospital Setting, Using Interpretive Phenomenological Analysis. & 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. Verification strategies for establishing reliability validity in qualitative research. 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. Kerlinger, F. N. (1964). 3. 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.

This can be due to many factors including poor question wording, bad instrument design or layout, illegibility of field notes, and so on. What, exactly, is observed by the three main approaches to research? Int J Qual Res, 1, pp.1â19. If your method has reliability⦠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. Understanding Reliability and Validity in Qualitative Research. Reliability shows how trustworthy is the score of the test. Validity. (1982). New York: Macmillan Publishing Co. Johnson, S. M., & Bolstad, O. D. (1973). Issues are still raised even now in the 21st century by the persistent concern with achieving rigor in qualitative research. There are many factors which can operate (during the course of a series of observations) to compromise the reliability of a measurement procedure. The measuring instrument in qualitative research consists of an individual without the support of standard instruments or baseline criteria. There is also a continuing debate about the analogous terms reliability and validity in naturalistic inquiries as opposed to quantitative investigations. All rights reserved. ANS Adv Nurs Sci. 2020 Dec 8;25:1450. doi: 10.4102/hsag.v25i0.1450. Frameworks for ensuring trustworthiness and rigour of qualitative research have been in existence for many years (Shenton 2004). Saslow, C. A. In this article, I have discussed about the threats to reliability in qualitative research and measures to enhance reliability. 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. 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. 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). New York: Pergamon. How is learning to be observed and recorded? synthesize the threats to validity and reliability in quantitative and qualitative parts of mixed methods research using the quality standards of each. Having a reliable measure or increasing the reliability of a measure does not guarantee validity, credibility, or transferability of research. 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. This research method helps us to gain an understanding to improve ideas, get new opinion based on a topic or issue that we undergoing. Even with good reliability over time in the observations of a single researcher, qualitative data still face problems with interrater reliability and, in turn, measurement construct validity. Assessing and reporting measurement reliability. Hillsdale, NJ: Lawrence Erlbaum Associates. Reid, J. As a measure of data quality, measures of interobserver agreement are simply that - measures of interobserver agreement. 2020 Aug 31;9:212. doi: 10.4103/jehp.jehp_703_19. The test is simply administered twice to the same subjects taking care to ensure that no learning or practice of the tested skills and understandings occurs during the two administrations. Threats to measurement reliability. Develop a qualitative research plan for a topic and research question applicable to a specific field of specialization. Cooper, J. O., Heron, T. E., & Heward, W. L. (1987). Journal of Applied Behavior Analysis, 10, 141-150. The test is administered to a sample of learners, the items in the test are divided into two halves (e.g. (1970). (1981). Applied behavior analysis. Is a move to evidence-based teaching practice feasible at this time? 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). An interesting result of a qualitative research: Academic exhaustion barrier to professionalism in medical students. Research methodology is judged for rigor and strength based on validity, and reliability of a research [Morris & Burkett, 2011]. Accordingly, qualitative research has a more difficult task when trying to establish the reliability and validity of its data. Noble, H. & Smith, J., 2015. University of Toronto, Toronto, Ontario, Canada . qualitative research also states that reliability is a consequence of the validity in a study. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Definition. Kazdin, A. E. (1977). Beliefs about the nature of reality and what can be observed. Elaborating on epistemological and theoretical conceptualizations by Lincoln and Guba, strategies congruent with qualitative perspective for ensuring validity to establish the credibility of the study are described. Critical Analysis of Strategies for Determining Rigor in Qualitative Inquiry. Observer reliability may be compromised by coding schemes which are too complex, by coding categories which are inadequately defined, by failing to provide adequate training for observers, by failing to provide observer reliability checks at regular intervals, by fatigue or loss of motivation on the part of observers, and so on.

Johnson H, Simons M, Newcomb D, Borkoles E. Int J Integr Care. Strictly speaking this procedure does not provide a measure of test reliability because each learner completes each item only once. Whereas quantitative researchers uses methods and designs to address threats to validity in advance of the research, qualitative researchers âmust try to rule out most validity threats after the research has begun, using evidence collected during the research itself to make these alternative hypotheses implausibleâ (Maxwell, 1996, p. 88). reliability in qualitative studies and in particular the tactics and strategies suggested by various qualitative researchers for avoiding or weakening the potential risks and threats. 2015 Sep;25(9):1212-22. doi: 10.1177/1049732315588501. 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. There is also a continuing debate about the analogous terms reliability and validity in naturalistic inquiries as opposed to quantitative investigations. 7-67). We then introduce an integrative framework of mixed methods research quality by Teddlie and Tashakkori (2003, see also and Tashakkori and Teddlie, 2008). However, to refresh your memory and ensure that we all attach the same meaning to validity, reliability and qualitative research⦠One important threat is low reliability of measures (see reliability). Introduction to measurement theory. 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. The Qualitative Report, 8(4), pp.597â607. The reader's reaction to differing levels of reported inter-occasion agreement depends to some extent on the complexity of the coding scheme which is being applied. 2010 What are the main issues in observing and recording learning? Validity is defined as the extent to which a concept is accurately measured in a quantitative study. If inter-marker agreement was being calculated for the marking and check marking of written answers to a set of mathematics exercises then anything less than 100% agreement between the two markers would probably be regarded as unreliable. Qualitative research has seen an increased popularity in the last two decades and is becoming widely accepted across most disciplines (e.g. Issues are still raised even now in the 21st century by the persistent concern with achieving rigor in qualitative research. sociology, medicine, business & economics, psychology, anthropology) (Huberman & Miles, 2002).

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).

Rural Homecare Nurses' Challenges in Providing Seamless Patient Care in Rural Japan. | The researcher then calculates the degree of inter-observer agreement (or inter-coder agreement) between the two independently obtained records. Methodological rigour within a qualitative framework. 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. 2020 Dec 13;17(24):9330. doi: 10.3390/ijerph17249330.

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. Artefact, bias, and complexity of assessment: the ABCs of reliability. ), Behavior change: Methodology, concepts and practice (pp. Modern educational measurement. Issues of validity and reliability in qualitative research. (This is most commonly referred to as the test-retest procedure for assessing test reliability.). In research, reliability means ârepeatabilityâ or âconsistencyâ; it is achieved if a measure will always provide the same result (Trochim, 2006). Hence, it is the science and philosophy behind all researches [Legesse, 2014]. 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?”. - 2021 Englewood Cliffs, NJ: Prentice Hall. Single case experimental designs: Strategies for studying behavior change (2nd ed.). Both of these measures are measures of the extent to which the two records of the same performance match each other. “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). 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). How is learning measured in the three main approaches to research? | Adolescent mothers' lived experiences whilst providing continuous kangaroo mother care: A qualitative study. 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. However, validity and reliability ⦠The use of reliability and validity are common in quantitative research and now it is reconsidered in the qualitative research paradigm. If the collected data shows the same results after being tested using various methods and sample groups, the information is reliable. For example, a survey designed to explore depression but which actually measures anxiety would not be considered valid. Reliability refers to the consistency of the measurement. Reliability in quantitative research stems from statistical results that have consistency (Roberts & Priest, 2006). Nevertheless, several writers on research methods, notably Silverman [1], have demonstrated how qualitative researchers can HHS (Some qualitative researchers use the term dependability.) CONCLUSION The subject study was well conducted and it fulfill majority of parameters including validity and reliability tests. 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). A note on the split-half method of calculating test “reliability”. The rejection of reliability and validity in qualitative inquiry in the 1980s has resulted in an interesting shift for âensuring rigorâ from the investigator's actions during the course of the research, to the reader or consumer of qualitative inquiry. Research methodology provides us the principles for organizing, planning, designing and conducting a good research. Qualitative Research Determine whether you are going to use interviewing or observation as your data recording technique. Often however, a less onerous procedure is used. In L. A. Hamerlynck, L. C. Handy, & E. J. Mash (Eds. NLM 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. Nahid Golafshani . 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). Beverly Hills: Sage Publications. Fundamental concepts of validity, reliability, and generalizability as applicable to qualitative research are then addressed with an update on the current views and controversies. Maxwell identified five threats to validity in qualitative research. 2006 May;53(5):319-28.
