criterion validity in qualitative research

Validity is a very important concept in qualitative HCI research in that it measures the accuracy of the findings we derive from a study. Note that reliability may differ between levels of measurement. Well-documented analyses, triangulation, and consideration of alternative explanations are recommended practices for increasing analytic validity, but they have their limits. Yun Yang, in Temporal Data Mining Via Unsupervised Ensemble Learning, 2017. Strategies for determining how much content to use for this purpose vary, but a general rule of thumb is to have multiple coders overlap in their coding of at least 10% of the sample. ity and validity in qualitative research is such a different process that quantitative labels should not be used. It is distinct from validity in that you can have a reliable indicator that does not really measure the latent variable. For minimizing bias errors, the researchers did not express to the participants opinions nor have any expectation. Coders must be trained especially well for making decisions based on latent meaning, however, so that coding decisions remain consistent within and between coders. AFC systems typically analyze behaviors in single images or video frames, and reliability is calculated on this level of measurement. Among the two most important properties are the validity and the reliability of the indicators. Yet, content analysis research attempts to minimize the influence of subjective, personal interpretations. We have repeated the experiment in order to confirm our initial findings with students. Moreover, a set of experiments on time series benchmark shown in Table 7.1 and motion trajectories database (CAVIAR) shown in Fig. Validity in qualitative research. This article explores the extant issues related to the science and art of qualitative research and proposes a synthesis of contemporary viewpoints. To obtain more solid evidence for the criterion validity of SNS engagement scales, validation researchers can improve the field by adopting more sophisticated alternative methods such as objective measures (e.g., objective logs) and mixed methods (e.g., subjective reports and objective logs). 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. A general definition of the reliability of an indicator is the variance of the ‘true’ (latent variable) variance divided by the total indicator variance. Level of measurement. Such coders must all be trained to use the coding scheme to make coding decisions in a reliable manner, so that the same television messages being coded are dealt with the same way by each coder each time they are encountered. The horizontal axis depicts the skew ratio while the vertical axis shows the given metric score. They were also given a deadline as in the real world to deliver the architecture documentation. However, validity in qualitative research might have different terms than in quantitative research. According to Lather (1991) he identified four types of validation (triangulation, construct validation, face validation, and catalytic validation) as a “reconceptualization of validation.”. 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). It is established through sampling as well as through attempts to reduce artificiality. Reliability has to do with whether the use of the same measures and research protocols (e.g., coding instructions, coding scheme) time and time again, as well as by more than one coder, will consistently result in the same findings. The F1 score or balanced F-score is the harmonic mean of precision and recall. For more details regarding each subtype—see Chapter 9 “Reliability and Validity” in Wrench et al. Credibility refers to believability or reasonableness. External validity has to do with the degree to which the study as a whole or the measures employed in the study can be generalized to the real world or to the entire population from which the sample was drawn. However, we believe there are practices common to all business-related (not critical or real time) domains. The last stage of the grounded theory method is the formation of a theory. Max Orovitz Building Room 315-A Furthermore, the generalizability of the system (i.e., its inter-system reliability in novel domains) must be maximized. They used both criterion validity and construct validity to measure the efficacy of the model and the scale (Suh et al., 2016). There are three primary approaches to validity: face validity, criterion validity, and construct validity (Cronbach and Meehl, 1955; Wrench et al., 2013). However, validity is better evidenced in quantitative studies than in qualitative research studies. That is, to take validity as an observable criterion in qualitative research and then to argue that it is possible for qualitative research to be properly valid. Construct validity is … The data sources may be different instances of the same type of data (for example, multiple participants in interview research) or completely different sources of data (for example, observation and time diaries). Inter-system reliability is the primary measure for the performance of an AFC system. If you decide to repeat your experiment, clear documentation of the procedures is crucial and careful repetition of both the original protocol and the analytic steps can be a convincing approach for documenting the consistency of the approaches. Interpretations that account for all—or as much as possible—of the observed data are easier to defend as being valid. Criterion validity. Other researchers use Pearson's correlation to determine the association between the coding decisions of one coder compared to another (or multiple others). The rejection of reliability and validity in qualitative inquiry in the 1980s has resulted in an interesting shift for "ensuring rigor" from the investigator’s actions during the course of the research, to the reader or consumer of qualitative inquiry. In our case, we did not restrict the teams to work in specific hours and times such as in a lab. According to Frey, (2018), They are Credibility, transferability, validity and reliability. According to Creswell & Poth (2013) they consider “validation” in qualitative research as it is trying to assess the “accuracy” of the results, as best described by the researcher, the participants, and the readers. Procedures and products of your analysis, including summaries, explanations, and tabular presentations of data can be included in the database as well. In addition, other TAM studies have also found similar correlations (Davis, 1989). Criterion validity relates to the ability of a method to correspond with other measurements that are collected in order to study the same concept. The Pearson correlation coefficient (PCC) is a linearity index that quantifies how well two vectors can be equated using a linear transformation (i.e., with the addition of a constant and scalar multiplication). Here Pa and Pb are labelings for two partitions that divide a data set of N objects into Ka and Kb clusters, respectively. It is important to match the analyzed level of measurement to the particular use-case of the system. The combination of a latent categorical variable with continuous effect indicators are less extensively developed than are the cases of continuous latent variables with continuous or categorical effect indicators. In order to compute intercoder reliability, the coders must code the same content to determine whether and to what extent their coding decisions align. We found that evidence supporting the criterion validity of SNS engagement scales is often derived from respondents’ self-report of their estimated time spent on the SNS or frequency of undertaking specific SNS behaviors. It is a test … Researcher bias refers to any kind of negative influence of the researcher’s knowledge, or assumptions, of the study, including the … Unlike quantitative researchers, who apply statistical methods for establishing validity and reliability of research findings, qualitative researchers aim to design and incorporate methodological strategies to ensure the ‘trustworthiness’ of the findings. Rooted in the positivist approach of philosophy, quantitative research deals primarily with the culmination of empirical conceptions (Winter 2000). On the other hand, that type of detailed measure enhances validity because it acknowledges that news stories can present degrees of positivity or negativity that are meaningful and potentially important with respect to how audiences actually respond to the stories. Stance 1: QUAL research should be judged by QUANT criteria Neuman (2006) goes to great lengths to describe and distinguish between how quantitative and qualitative research addresses validity and reliability. If you can show that your interpretation is firmly grounded in the data, you go a long way towards establishing validity. Because such labels are used to train and evaluate supervised learning systems, inter-observer reliability matters. https://www.deakin.edu.au/__data/assets/pdf_file/0004/681025/Participant-observation.pdf, Whittemore, R., Chase, S. K., & Mandle, C. L. (2001). Latent class or latent structure analysis (Lazarsfeld and Henry 1968) also deals with effect indicators. Rigor is simply defined as the quality or state of being very exact, careful, or with strict precision8 or the quality of being thorough and accurate.9 The term qualitative rigor itself is an oxymoron, considering that qualitative research is a journey of explanation and discovery tha… University of Miami, School of Education and Human Development Still other formulas, such as Scott's pi, take chance agreement into consideration. In 1984, ANES even discovered voting records in a garbage dump. The weighted consensus function has outstanding ability in automatic model selection and appropriate grouping for complex temporal data, which has been initially demonstrated on a complex Gaussian-generated 2D-data set shown in Fig. Construct validity, for instance, assesses whether the indicator is associated with other constructs that it is supposed to relate to and not associated with those that it should not. From traditional validity testing in quantitative research study, scholars have initiated determination of validity in qualitative studies as well (Golafshani 2003). Finally, we proposed a Weighted clustering ensemble with multiple representations in order to provide an alternative solution to solve the common problems such as selection of intrinsic cluster numbers, computational cost, and combination method raised by both former proposed clustering ensemble models from the perspective of a feature-based approach. Phone: 305-284-2869 Inter-observer reliability refers to the extent to which labels assigned by different human annotators are consistent with one another. Reliability of measurement. Though it is difficult to maintain validity in qualitative research but there are some alternate ways in which the … The content analysis codes or categories used to measure the healthiness of the foods and beverages shown in commercials would ideally reflect all of these potential indicators of the concept. Carmines and Zeller argue that criterion validation has limited use in the social sciences because often there exists no direct measure to validate against. Of course, true objectivity is a myth rather than a reality. The degree of classification error of the observed categorical variables provides information on the accuracy of the indicator. Votes may be improperly recorded. In a recent study, Suh and her colleagues developed a model for user burden that consists of six constructs and, on top of the model, a User Burden Scale. Secondly, reliability and validity as used in quantitative research are discussed as a way of providing a springboard to examining what these two terms mean and how they can be tested in the qualitative research paradigm. This may not be a bad thing—rival explanations that you might never find if you cherry-picked your data to fit your theory may actually be more interesting than your original theory. There is a threat that the academic context is not similar to industrial. As the example of ANES vote validation demonstrates, criterion validity is only as good as the validity of the reference measure to which one is making a comparison. The choice of correlation type should depend on how measurements are obtained and how they will be used. Qualitative Health Research, 11, 522–537. Accuracy, as stated earlier, is the percentage of agreement. If the causal indicator itself contains measurement error, then this needs to be part of the measurement model. Metrics for quantifying reliability. Rigor of qualitative research continues to be challenged even now in the 21st century—from the very idea that qualitative research alone is open to questions, so with the terms rigor and trustworthiness. Lincoln and Guba (1985) used “trustworthiness” of a study as the naturalist’s equivalent for internal validation, external validation, reliability, and objectivity. That does not mean that criterion validation may be useful in certain contexts. Whittemore, Chase, and Mandle (2001), analyzed 13 writings about validation and came up with key validation criteria from these studies. Michael P. McDonald, in Encyclopedia of Social Measurement, 2005. The other type of validity is internal validity, which refers to the closeness of fit between the meanings of the concepts that we hold in everyday life and the ways those concepts are operationalized in the research. In HCI research, establishing validity implies constructing a multifaceted argument in favor of your interpretation of the data. Validity shows how a specific test is suitable for a particular situation. The researcher wants to determine what proportion of the newscast is devoted to coverage of the presidential candidates during election season, as well as whether those candidates receive positive or negative coverage. Construct validity: The internal consistency of the questions was verified with the Cronbach’s α. See Nunnally and Bernstein (1994) for further discussion. Contact Information: The criteria of sample selection should be in accordance with the topic and aims of the research. Under such an approach, validity determines whether the research truly measures what it was intended to measure. In studies of television content, the goals of establishing validity and reliability must be balanced. It is critical to understand rigor in research. 7.2 as the motivation described in Section 7.2.1, then a set of experiments on time series benchmarks shown in Table 7.1 in comparison with standards temporal data clustering algorithms, Table 7.2 in comparison with three state-of-the-art ensemble learning algorithms, Table 7.3 in comparison with other proposed clustering ensemble models on motion trajectories database (CAVIAR). To attempt to resolve this issue, a number of alternative metrics have been developed including the F-score, receiver operator characteristic (ROC) curve analyses, and various chance-adjusted agreement measures. Jonathan Lazar, ... Harry Hochheiser, in Research Methods in Human Computer Interaction (Second Edition), 2017. To confirm that the results are transferable between the researcher and those being studied, thick description is needed. Leif Sigerson, Cecilia Cheng, in Computers in Human Behavior, 2018. Adapted from [37]. In addition to training coders on how to perform the study, a more formal means of ensuring reliability— calculations of intercoder reliability—is used in content analysis research. However, accuracy is a poor choice when the categories are highly imbalanced, such as when a facial behavior has a very high (or very low) occurrence rate and the algorithm is trying to predict when the behavior did and did not occur. There are three primary approaches to validity: face validity, criterion validity, and construct validity (Cronbach and Meehl, 1955; Wrench et al., 2013). Content validity examines whether the indicators are capturing the concept for which the latent variable stands. Qualitative research does not lend itself to such mathematical determination of validity, rather it is highly focused on providing descriptive and/or exploratory results. From the technical perspective, construct or factorial validity is based on the statistical technique of “factor analysis” that allows researchers to identify the groups of items or factors in a measurement instrument. According to Creswell & Poth (2013) they consider “validation” in qualitative research as it is trying to assess the “accuracy” of the results, as best described by the researcher, the participants, and the readers. A discussion that shows not only how a given model fits the data but how it is a better fit than plausible alternatives can be particularly compelling. It also makes a number of assumptions that might be difficult to satisfy in practice. Construct or factorial validity is usually adopted when a researcher believes that no valid criterion is available for the research topic under investigation. While this may sound like the ideal case of validating a fallible human response to an infallible record of voting, the actual records are not without measurement error. Well-documented data and procedures are necessary, but not sufficient for establishing validity. Inter-system reliability refers to the extent to which labels assigned by AFC systems are consistent with labels assigned by human annotators. Qualitative inquiry and research design : Choosing among five approaches (Fourth ed.). To operationalize these terms, long engagement in the field and the triangulation of data sources, methods, and investigators to establish credibility.
