294–295). Although the tests and measures used to establish 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 evaluate qualitative research.2–4 In the broadest context these terms are applicable, with validity referring to the integrity and application of … But how do researchers know that the scores actually represent the characteristic, especially when it is a construct like intelligence, self-esteem, depression, or working memory capacity?

One of the key factors affecting validity and reliability is error. It depends on the nature of the measurement (e.g., focus/attention affects reaction times, hunger/tiredness leads to reduced physical/mental performance, etc.). 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. (2002, p. 15) concluded that this had resulted in a “plethora” of terms and criteria that often brought more confusion than clarity in establishing the validity of qualitative research. It is, however, with a more general discussion of qualitative inquiry and validity that my exploration must begin. Member checking and peer debriefing, for example, can be applied in all three paradigms. Many qualitative researchers still regard these criteria as methodological standards. Please read and accept the terms and conditions and check the box to generate a sharing link. Negative case selection is the process of data analysis through which the interpretation of the data is stretched by consciously seeking out and explaining outliers (negative cases) in the data (see also Miles & Huberman, 1994). Two fundamental criteria of measurement in scientific research are reliability and validity [19,20,[43][44][45][46] [47] [48]. The social interaction with the respondent thus requires tact and sensitivity of the researcher. (p. 301). Change ), You are commenting using your Twitter account. In community and social work, it seems the reverse is at work. But for an evaluator or policy researcher who has to make an assessment of the impact of a social measure in, say, 2 months because the political situation calls for it, the situation is different. Related approaches call for a political function of qualitative research by requiring that they should be focused on bringing change of one kind or another: for example, by challenging capitalism, racism, homophobia, or social disadvantage. Validity also establishes the soundness of the methodology, sampling process, d… what are its main working components (process evaluation)? Given their properties and focal points, these evaluation purposes can be linked with the paradigm assumptions Creswell and Miller distinguish. It elegantly unites different worldviews or paradigms within qualitative research with key perspectives by which the validity of qualitative research can be assessed: that of the researcher, the respondent, and the external reader. In their eyes, qualitative research should certainly be transparent and accountable but not at the expense of the interests of the respondent and its context. Creswell and Millers’ work advances the debate on validity in qualitative research in several ways. By highlighting these errors, both researcher and end-user more fully appreciate research outcomes and understand what they have (or don’t have). For instance, because it turns out that practitioners of a social program do not perform well or that their particular approach is actually counterproductive. Naturally, as is the case with Cresswell and Miller’s original model, the assessment procedures are partly interchangeable. If you have the appropriate software installed, you can download article citation data to the citation manager of your choice. However, the concept of determination of the credibility of the research is applicable to qualitative data. Can methodological choices be justified? If the evaluation has an emancipatory intent (empowerment), then reflexivity of the researcher in the study becomes particularly important. Moreover, in several European countries, institutions and government agencies that are active in community and social work have set up databases of “effective interventions” analogous to the already established evidence-based databases in the health sectors (treating interventions as “independent instruments”: postpositivist paradigm, see, e.g., the Cochrane reviews and Campbell Collaboration). Qualitative research methods primarily include observations and interviews where the researcher charts behavior … At the same time, we should not simply accept at face value methodological pluralism, reinforcing it by treating each qualitative approach as having its own unique set of quality criteria. what are its working components? Qualitative research requires that the researcher talks to people and observes them up close and captures their behaviors and experiences accurately. the site you are agreeing to our use of cookies. Not because ethical considerations are not important, but because the objective of upholding certain ethical standards in evaluation research is to some extent naïve. Department of Health/NHS Institute for Innovation and Improvement. Table 1. The procedures within this paradigm hence look for an alternative vocabulary for validity labels, for example, transferability instead of “external validity.” The third paradigm assumption involves the critical perspective. It is important to note that the framework presented in this article can serve as a checklist for qualitative evaluations. However, another reply, that … What factors affecting the reliability and validity of data might you need to analyze? Credibility as an element of validity of qualitative research denotes the extent to which the research approach and findings remain in sync with generally accepted natural laws and phenomenon, standards, and observations. On what data are these conclusions based? 1.One can pose the question if the model should be supplemented with ethical criteria, such as those formulated by Davies and Dodd (2002). It can contribute to or focus on the instrumental effectiveness of the policy itself (does it work? It argues that different purposes of qualitative evaluations can be linked with different scientific paradigms and perspectives, thus transcending unproductive paradigmatic divisions as well as providing a flexible yet rigorous validity framework for researchers and … It argues that different purposes of qualitative evaluations can be linked with different scientific paradigms and perspectives, thus transcending unproductive paradigmatic divisions as well as providing a flexible yet rigorous validity framework for researchers and reviewers of qualitative evaluations. It can be expected, therefore, that practitioners and policy makers will continue to make use of different types of qualitative evaluations—emphasizing different purposes and starting from different paradigms—to evaluate their specific programs and policies. Today, still, methodological textbooks on this point show a lot of overlap and most criteria are directly obtained from the themes first conceptualized by Guba and Lincoln. Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article. The constructivist researcher assumes more pluralistic, interpretive, and contextualized perspectives of reality (i.e., sensitive to time, place, and situation). ), the criteria triangulation, member checking, and conducting an audit trail are essential. Its aim is to minimize the risk of misinterpretations by the researchers. Qualitative data is as important as quantitative data, as it also helps in establishing key research points. What are additional effects? While it’s fundamentally important to have correctly recruited respondents and researchers who have good eliciting and listening skills, know how to manage interpersonal dynamics, build relationships,analyse and interpret(the foundations of quality), it is possible for their styles and approaches to vary dramatically. Given its main purpose—evaluating the effectiveness of the program itself—it is essential that from the evaluator’s perspective, triangulation is performed (do findings from interviews with teenagers, observations of the execution of the program by practitioners and document analysis overlap?) The study thereby provided depth to the understanding of problem-solving interventions for informal hospice caregivers which can be used to enhance existing support services. Therefore, the measurement is not valid. In marketing research in particular, insight and understanding is the goal, and the variability of interviewers/ situations/ techniques can be seen as a benefit in bringing different perspectives to bear on the research problem. Credibility refers to believability or reasonableness. I totally agree. Find out about Lean Library here, If you have access to journal via a society or associations, read the instructions below. Although validity in qualitative research has been widely reflected upon in the methodological literature (and is still often subject of debate), the link with evaluation research is underexplored. In the positivistic, rational tradition of science methodology, “validity” can be defined as the degree to which the indicators or variables of a research concept are made measurable, accurately represent that concept. These criteria counterbalance a too-one-sided report of the experiences of particular individuals (disconfirming evidence) or circumstances (prolonged engagement) and allow for a thorough understanding of the experiences of respondents (thick description). This perspective emerged as a critique of alleged structural inequalities of modern society and power structures and was embraced among qualitative researchers who committed to the empowerment of marginalized groups, for instance, through action research (see e.g., Barnes & Cotterell, 2011; Reason & Bradbury, 2001). But the model nonetheless poses priority in which procedures are especially important for what paradigm and evaluation purpose. Change ), You are commenting using your Facebook account. Validity Procedures Within Qualitative Lens and Paradigm Assumptions. The health sector in particular has seen a surge in approaches and writings on evidence-based procedures and evaluation research that involve or require inclusion of qualitative methods (see, e.g., Pope & Mays, 2006). Potential variability associated with the: IMHO you forgot the main aspect: the recruitment quality. In the case study, interviews, observations, and documentation analysis are conducted. Staying with our hypothetical example, research questions in such an evaluation could read: Did the teenage pregnant mothers themselves benefit from the information gathered in the evaluation? Validity and reliability In Research 2. Validity in qualitative research can also be checked by a technique known as respondent validation. Error is inherent in all investigations and is inversely related to validity and reliability. Under such an approach, validity determines whether the research truly measures what it was intended to measure. Should the qualitative researcher be transparent about such possible outcomes in advance, then it would be unlikely he or she could count on much cooperation from respondents in the field. Post was not sent - check your email addresses! The concept of reliability in qualitative research needs to be studied keeping in mind the interpretivist or naturalist paradigm of the research. What Hammersley shows with this example is that research in the social domain is framed by a series of value assumptions which can produce serious differences. How do the trainers shape it? It seems to me that applying values from additional paradigms of thinking, may assist in evaluating the contributions of qualitative/ affective research. For a large part, the report draws on the input from key stakeholders who attended workshops and sets out arguments for how the NHS can improve services and patients’ experience of health care (see Robert & Cornwell, 2011).

Validity relates to the appropriateness of any research value, tools and techniques, and processes, including data collection and validation (Mohamad et al., 2015). Lean Library can solve it. However, the thermometer has not been calibrated properly, so the result is 2 degrees lower than the true value. Learn how your comment data is processed. In this sense, one must keep in mind that the framework is an ideal type. Thick description involves the detailed description of the setting, the participants, and the themes of the study. Discussion Please talk about the level of reliability and validity of your results and their influence on values. This article provides a discussion on the question of validity in qualitative evaluation. Detail is the key word here. Obviously, this rational definition of validity does not work well in qualitative naturalistic research—which does not focus on variables on interval or ratio level. Like Rolfe and Sandelowski, Hammersley ultimately rejects the idea that a final set of universal criteria can be formulated. One also has to share the assumption that certain disparities in the classroom affect educational performance, defined in terms of exam success. Several authors have therefore sought to develop specific research procedures and criteria aimed at increasing the validity of qualitative outcomes. The countless discussions and experiments conducted on various aspects of survey design give ongoing support for a “quality framework” by which providers and users can gauge research results. Thank you, Joanna. The more the categories and conclusions are confirmed by different data sources, the more valid the results. METHODS: Due to limited behavioral studies related to child MITS, we developed an innovative qualitative methodology to determine the barriers, facilitators, and other factors that affect the implementation and sustainability of CHAMPS surveillance across 7 diverse locations in sub-Saharan Africa and South Asia. Sample size: The data collection tool used in research – in particular, questionnaires and interview schedules, are tested for their reliability to ensure they are not sensitive to the research conditions / researcher / respondents, etc. In their 2001 paper (“Why We Need to Reassess Focus Group Research”), Catterall and Clarke discuss the work that has been done in focus group research to better understand the effect of variables such as: the inclusion of professional participants, the presence of observers, and interviewer (moderator) effects. Thank you, Andrea. One such classification scheme looks like this: 13 Factors Impacting the Quality of Qualitative Research. According to Guba and Lincoln, each paradigm requires specific criteria to determine the veracity of the research. And, yes, I agree—the researcher IS the instrument, and honing our skills is critical to quality in both qual and quant. While research-on-research is critical to improving the quality of what we do, the qualitative marketing research world has been blatantly absent from the investigative scene. Instrumental effectiveness corresponds to postpositivism. To accept this as a relevant research topic, argues Hammersley, it is vital that one believes in the equality of the sexes (which may not be shared by certain religious groups or sociobiologists). Does it work? View or download all the content the society has access to. In case of a qualitative evaluation that primarily focuses on the instrumental effectiveness of a particular policy or program (does it work? ), and it can follow an emancipatory approach in which the research itself aims to empower or educate those involved in the program (see, e.g., the many forms of participatory action research).

Login failed. Such alternative criteria should be much more formulated in terms of education, politics, ethics, aesthetics, or even economics (e.g., does the study offer value for money?). FACTORS AFFECTING RELIABILITY ESTIMATE Range of Ages. Triangulation can be enhanced by contrasting outcomes with findings from other types of research or previous research outcomes (see Onwuegbuzie & Leech, 2007). Prolonged engagement implies that the investigator performs the study for a considerable period. Sandelowski, 1993, p. 3). In the wake of Guba and Lincoln, many authors supplemented or perfected their criteria, or suggested alternative terminology for similar procedures. It is critical to understand rigor in research. On the other hand, Patton (2001) states that validity and reliability are two factors which any qualitative researcher should be concerned about while designing a study, analysing results and … If the goal is to uncover the meaning of the intervention for clients and target groups, then the research should acknowledge disconfirming evidence (or negative case selection), there must be prolonged engagement in the field (not a snapshot study) and external readers should be able to identify the experiences of respondents adequately through thick description. How do the teenagers experience the support program? In positivism or quantitative research, the use of reliability and validity is very common but the questions always arise that how to maintain the concept of reliability in qualitative research studies. Each procedure in effect serves as a counterweight for inherent methodological weaknesses of the respective evaluation purposes. Historically, highly influenced by postmodern and constructivist schools of thought, programs in community and social work are now increasingly fitted into experimental or “quantized” research models reminiscent of the old modus operandi in the health sector. (, Rossi, P. H., Lipsey, M. W., Freeman, H. E. (, Washington, K. T., Demiris, G., Oliver, D. P., Wittenberg-Lyles, E., Crumb, E. (, Whittemore, R., Chase, S. K., Mandle, C. L. (. Rooted in the positivist approach of philosophy, quantitative research deals primarily with the culmination of empirical conceptions (Winter 2000). In this article, I will explore aspects of validity of qualitative research with the explicit objective of connecting them with aspects of evaluation. This product could help you, Accessing resources off campus can be a challenge. Elliott, Fischer, and Rennie (1999, p. 221) argue for “owning one’s perspective,” whereby authors specify their theoretical orientations and personal anticipations, both as known in advance and as they become apparent during the research (see also Choudhuri, Glauser, & Peregoy, 2004; Morrow, 2005). Oliver, Aicken, and Arai (2013) used this procedure to help policy makers make better decisions on childhood obesity. Excerpts and links may be used, provided that full and clear credit is given to Margaret R. Roller and Research Design Review with appropriate and specific direction to the original content. Its most important feature is that it avoids “taking sides” in a paradigmatic and epistemological sense. These lenses constitute the researchers’ own perspective, that of the participants in the research or that of external reviewers or readers. FundingThe author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: Financial support for the study underlying this article was received from Movisie, Netherlands Institute for Social Development; RIVM National Institute for Public Health and the Environment; Netherlands Institute for Sport and Physical Activity. Within the postpositivist worldview, a particular social program or policy is primarily seen as a separate entity—as an “instrument”—whose independent effect can be evaluated accordingly. Change ), You are commenting using your Google account. Potential variability associated with the: Particular venue/setting (incl., face-to-face and online) Presence of observers/interviewers as well as other participants (e.g., groups … The principle of fair dealing (Dingwall, 1992; see also Mays & Pope, 2000) is a logical addition to disconfirming evidence and is particularly relevant when the evaluation aims to uncover multiple realities. Some of the reasons for this are an increased understanding and acknowledgment of the limits of experiment or questionnaire-based quantitative research on “what works” (see, e.g., Oakley, Strange, Bonell, Allen, & Stephenson, 2006; Roe & Lysaker, 2012; Lub, 2014), a growing demand for ethical considerations in evaluations (see, e.g., Parahoo, 2014), insight into clients’ and patients’ well-being (see, e.g., Haber, Carlson, & Braga, 2014), and the need for a more thorough understanding of how experimentally determined evidence-based interventions connect to people’s emotions, culture, experiences, and habits (see, e.g., Gibbs, Jewkes, Sikweyiya, & Willan, 2015; Lohan, Aventin, Maguire, Clarke, Linden & McDaid, 2014). Most EU Research Calls demand involvement of practitioners and negotiations with stakeholders and require that proposals elaborate on how such “end users” will benefit from the undertaken research. ... VALIDITY IN QUALITATIVE RESEARCH. By linking these purposes and paradigms, we can create a new model with relevant validity criteria, specifically for qualitative evaluation (see Table 2). Coventry: NHS Institute for Innovation and Improvement, Concerns and issues that have emerged with the evolution of evidence-based practice, Validity, trustworthiness and rigour: Quality and the idea of qualitative research, Rigor or rigor mortis: The problem of rigor in qualitative research revisited, When does evidence-based policy turn into policy-based evidence? How does a client, an end-user, or buyer evaluate the quality of our qualitative research? Researchers should describe, for instance, interactions with informants, personal experiences, or provide a detailed description of the emotions of the respondents. Davies and Dodd (2002) argue that because of this, the quest for greater rigor cannot be separated from the interaction with the research subject and the ethics that the researcher should take into account (see, e.g., Grol, 2001, on building bridges between professional pride, payer profit, and patient satisfaction).
