A. Shaffer et al. This example demonstrates that researchers who use systematically biased measures cannot accurately assess discriminant validity. One thing that we can say is that the convergent correlations should always be higher than the discriminant ones. It only detects a lack of discriminant validity in more than 50% of simulation runs in situations with very heterogeneous loading patterns (i.e., 0.50 /0.70 /0.90) and sample sizes of 500 or less. While item-level correlations or their disattenuated versions could also be applied in principle, we have seen this practice neither recommended nor used. This idea is adapted from Cheung and Rensvold’s (2002) proposal in the measurement invariance literature, and the .002 cutoff is based on the simulation by Meade et al. You can be signed in via any or all of the methods shown below at the same time. and discriminant validity.27 The internal consistency was validated using composite reliability (CR), threshold value: 0.70. There are also two 3x3 blocks of discriminant coefficients (shown in red), although if you’re really sharp you’ll recognize that they are the same values in mirror image (Do you know why? Overall, χ2(cut) and CICFA (cut) can be recommended as general solutions because they meet the definition of discriminant validity, have the flexibility to adapt to various levels of cutoffs, and can be extended to more complex scenarios such as nonlinear measurement models (Foster et al., 2017), scales with minor dimensions (Rodriguez et al., 2016), or cases in which factorial validity is violated because of cross-loadings. Another group of researchers used discriminant validity to refer to whether two constructs were empirically distinguishable (B in Figure 1). While a general set of statistics and cutoffs that is applicable to all research scenarios cannot exist, we believe that establishing some standards is useful. (2015). Finally, we compare the techniques in a comprehensive Monte Carlo simulation. Notice, however, that while the high intercorrelations demonstrate the the four items are probably related to the same construct, that doesn’t automatically mean that the construct is self esteem. Eunseong Cho is a professor of marketing in the College of Business Administration, Kwangwoon University, Republic of Korea. χ2(merge), χ2(1), and CICFA(1) can be used if theory suggests nearly perfect but not absolutely perfect correlations. However, the test also has a major weakness that, in contrast to χ2(1), this test cannot be extended to other cutoffs (i.e., χ2(cut)). For statistics with meaningful interpretations, we assessed the bias and variance of the statistic and the validity of the CIs. A significant result from a nested model comparison means that the original interval hypothesis can be rejected. The email address and/or password entered does not match our records, please check and try again. If the correlation is not significantly different, repeat the model comparison by selecting the high cutoff for the next higher section (in this case 1). This result was expected because all these approaches are consistent and their assumptions hold in this set of conditions. The first three types of validity are different facets of convergent validity, the degree to which one means of measuring a construct agrees with another (Kidder & Judd, 1986). The first set of rows in Table 6 shows the effects of sample size. Multiple comparison corrections address this issue by adjusting the individual test α level to keep the familywise Type I error at the intended level. Our definition has several advantages over previous definitions shown in Table 2. Factor correlation estimation. (A) Items measure more than one construct (i.e., cross-loadings). For example, defining discriminant validity in terms of a (true) correlation between constructs implies that a discriminant validity problem cannot be addressed with better measures. If you have access to a journal via a society or association membership, please browse to your society journal, select an article to view, and follow the instructions in this box. Some studies demonstrated that correlations were not significantly different from zero, whereas others showed that correlations were significantly different from one. He earned his PhD from the Korea Advanced Institute of Science and Technology in 2004. One is CICFA(sys), which is based on the confidence intervals (CIs) in confirmatory factor analysis (CFA), and the other is χ2(sys), a technique based on model comparisons in CFA. They can also be useful as a first step in discriminant validity assessment; if any of them indicates a problem, then so will any variant of the techniques that use a cutoff of less than 1. We hypothesized that our DSM-based structured diagnostic interview for ASDs would have good concurrent and discriminant validity. Find the correlation among the construct (you must use the average you computed for each construct in step 1 above). He runs a research methods–focused YouTube channel at https://www.youtube.com/mronkko. Second, scrutinize the measurement model. In summary, CICFA(cut) and χ2(cut) are generally the best techniques. However, the few empirical studies that defined the term revealed that it can be understood in two different ways: One group of researchers used discriminant validity as a property of a measure and considered a measure to have discriminant validity if it measured the construct that it was supposed to measure but not any other construct of interest (A in Figure 1). Table 7 Discriminant Validity (HTMT Ratio) BI Mediato r PI SP Adv BI Mediato r 0.484 PI 0.64 0.478 SP 0.732 0.454 0.611 adv 0.387 0.441 0.43 0.349 Table 7 shows the HTMT ratio, which is an effective approach to access discriminant validity. Convergent and discriminant validation by the multitrait-multimethod matrix. These two variables also have different causes and consequences (American Psychological Association, 2015), so studies that attempt to measure both can lead to useful policy implications. Paradoxically, this power to reject the null hypothesis has been interpreted as a lack of power to detect discriminant validity (Voorhees et al., 2016). The original criteria, illustrated in Table 3, were as follows: (a) two variables that measure the same trait (T1) with two different methods (M1, M2) should correlate more highly than any two variables that measure two different traits (T1, T2) with different methods (M1, M2); (b) two variables that measure the same trait (T1) with two different methods (M1, M2) should correlate more highly than any two variables that measure two different traits (T1, T2) but use the same method (M1); and (c) the pattern of correlations between variables that measure different traits (T1, T2) should be very similar across different methods (M1, M2) (Campbell & Fiske, 1959). Mikko Rönkkö is associate professor of entrepreneurship at Jyväskylä University School of Business and Economics (JSBE) and a docent at Aalto University School of Science. 4.Of the AMJ and JAP articles reviewed, most reported a correlation table (AMJ 96.9%, JAP 89.3%), but most did not specify whether the reported correlations were scale score correlations or factor correlations (AMJ 100%, JAP 98.5%). Nevertheless, it is clear that the CFI comparison does not generally have a smaller false positive rate than χ2(1). ABN 56 616 169 021. (, Green, D. P., Goldman, S. L., Salovey, P. (, Green, J. P., Tonidandel, S., Cortina, J. M. (, Hamann, P. M., Schiemann, F., Bellora, L., Guenther, T. W. (, Henseler, J., Ringle, C. M., Sarstedt, M. (, Jorgensen, T. D., Pornprasertmanit, S., Schoemann, A. M., Rosseel, Y. A. Shaffer et al. However, most studies use only the lower triangle of the table, leaving the other half empty (AMJ 93.6%, JAP 83.1%). (2010) diagnosed a discriminant validity problem between job satisfaction and organizational commitment based on a correlation of .91, and Mathieu and Farr (1991) declared no problem of discriminant validity between the same variables on the basis of a correlation of .78. We refer to this rule as AVE/SV because the squared correlation quantifies shared variance (SV; Henseler et al., 2015). Full size table. Disattenuated correlations are useful in single-item scenarios, where reliability estimates could come from test-retest or interrater reliability checks or from prior studies. Instead of using the default scale setting option to fix the first factor loadings to 1, scale the latent variables by fixing their variances to 1 (A in Figure 2); this should be explicitly reported in the article. Our review of the literature provides several conclusions. That is, patients with hypertension are further subdivided into three stages according to their blood pressure level, and each level is associated with different treatments. And the answer is – we don’t know! 3.The desirable pattern of correlations in a factorial validity assessment is similar to the pattern in discriminant validity assessment in an MTMM study (Spector, 2013), so in practice the difference between discriminant validity and factorial validity is not as clear-cut. If the factors are rotated orthogonally (e.g., Varimax) or are otherwise constrained to be uncorrelated, the pattern coefficients and structure coefficients are identical (Henson & Roberts, 2006). Thus, while marketed as a new technique, the HTMT index has actually been used for decades; parallel reliability is the oldest reliability coefficient (Brown, 1910), and disattenuated correlations have been used to assess discriminant validity for decades (Schmitt, 1996). OK, so how do we get to the really interesting question? Correlations between theoretically similar measures should be “high” while correlations between theoretically dissimilar measures should be “low”. While some of the model fit indices do depend on factor correlations, they do so only weakly and indirectly (Kline, 2011, chap. We acknowledge the computational resources provided by the Aalto Science-IT project. The effect for other techniques was an increase in precision, which was expected because more indicators provide more information from which to estimate the correlation. A notable exception is Reichardt and Coleman (1995), who criticized the MTMM-based criteria for being dichotomous and declared that a natural (dichotomous) definition of discriminant validity outside the MTMM context would be that two measures x1 and x2 have discriminant validity if and only if x1 measures construct T1 but not T2, x2 measures T2 but not T1, and the two constructs are not perfectly correlated. The term “ A common criticism is that the correction can produce inadmissible correlations (i.e., greater than 1 or less than –1) (Charles, 2005; Nimon et al., 2012), but this issue is by no means a unique problem because the same can occur with a CFA. Equation 3 shows an equivalent scale-level comparison (part of category 1 in Table 2) focusing on two distinct scales k and l. The factor correlations are solved from the interitem correlations by multiplying with left and right inverses of the factor pattern matrix to correct for measurement error and are then compared against a perfect correlation. All bootstrap analyses were calculated with 1,000 replications. But, neither one alone is sufficient for establishing construct validity. Generalizing the concept of discriminant validity outside MTMM matrices is not straightforward. This effect is seen in Table 11, where the pattern of results for CFA models was largely similar between the cross-loading conditions, but the presence of cross-loadings increased the false positive rate. In contrast, defining discriminant validity in terms of measures or … Even the two relatively low correlations (between informant-report and Time 1 (2016) suggest that comparing the differences in the CFIs between the two models instead of χ2 can produce a test whose result is less dependent on sample size than the χ2(1) test. This inconsistency might be an outcome of researchers favoring cutoffs for their simplicity, or it may reflect the fact that after calculating a discriminant validity statistic, researchers must decide whether further analysis and interpretation is required. The Iris flower data set, or Fisher's Iris dataset, is a multivariate dataset introduced by Sir Ronald Aylmer Fisher in 1936. The inappropriateness of the AVE as an index of discriminant validity. To understand what organizational researchers try to accomplish by assessing discriminant validity, we reviewed all articles published between 2013 and 2016 by the Academy of Management Journal (AMJ), the Journal of Applied Psychology (JAP), and Organizational Research Methods (ORM). The third set of rows in Table 6 demonstrates the effects of varying the factor loadings. We then review techniques that have been proposed for discriminant validity assessment, demonstrating some problems and equivalencies of these techniques that have gone unnoticed by prior research. By continuing to browse Voorhees et al. Lean Library can solve it. Beyond this definition, the term can refer to two distinct concepts, factor pattern coefficients or factor structure coefficients (see Table 5), and has been confusingly used with both meanings in the discriminant validity literature.15 Structure coefficients are correlations between items and factors, so their values are constrained to be between –1 and 1. This finding and the sensitivity of the CFI tests to model size, explained earlier, make χ2(cut) the preferred alternative of the two. Table 6. 18.The two hypothetical measures have a floor and ceiling effect, which leads to nonrandom measurement errors and a violation of the assumption underlying the disattenuation. Table 5. Figure 6. Online Supplement 4 provides a tutorial on how to implement the techniques described in this article using AMOS, LISREL, Mplus, R, and Stata. Across many theoretical frameworks these functions include planning, organizing, sequencing, problem solving, decision-making, goal selection, switching between task sets, monitoring for conflict, monitoring for task-relevant information, monitoring performance levels, updating working memory, interference suppressio… Maybe there’s some other construct that all four items are related to (more about this later). Instead, it appears that many of the techniques have been introduced without sufficient testing and, consequently, are applied haphazardly. This is a genuine problem with the χ2(1) test, and two proposals for addressing it have been presented in the literature. 1.The existence of constructs independently of measures (realism), although often implicit, is commonly assumed in the discriminant validity literature. Clearly, none of these techniques can be recommended. In the studies that considered discriminant validity as the degree to which each item measured one construct only and not something else, various factor analysis techniques were the most commonly used, typically either evaluating the fit of the model where cross-loadings were constrained to be zero or estimating the cross-loadings and comparing their values against various cutoffs. Discussion . Table 11. The lack of a perfect correlation between two latent variables is ultimately rarely of interest, and thus, it is more logical to use a null hypothesis that covers an interval (e.g., ϕ12>.9). A. Shaffer et al., 2016). This product could help you, Accessing resources off campus can be a challenge. The covariances between factors obtained in the latter way equal the correlations; alternatively, when using CICFA(sys), the standardized factor solution can be inspected. The heterotrait-monotrait (HTMT) ratio was recently introduced in marketing (Henseler et al., 2015) and is being adopted in other disciplines as well (Kuppelwieser et al., 2019). Please read and accept the terms and conditions and check the box to generate a sharing link. Fourth, the definition is not tied to either the individual item level or the multiple item scale level but works across both, thus unifying the category 1 and category 2 definitions of Table 2. This tendency has been taken as evidence that AVE/SV is “a very conservative test” (Voorhees et al., 2016, p. 124), whereas the test is simply severely biased. However, we recommend CICFA(cut) for practical reasons. The proposed classification system should be applied with CICFA(cut) and χ2(cut), and we propose that these workflows be referred to as CICFA(sys) and χ2(sys), respectively. ORCID iDMikko Rönkkö https://orcid.org/0000-0001-7988-7609, Eunseong Cho https://orcid.org/0000-0003-1818-0532. That is, a correlation that is not specified as a factor correlation can almost always be regarded as a scale score correlation. One of the most powerful approaches is to include even more constructs and measures. In cases such as this where the constructs are well defined, large correlations should be tolerated when expected based on theory and prior empirical results. (2016) and Podsakoff et al. Following Cho’s (2016) suggestion and including the assumption of each reliability coefficient in the name will hopefully also reduce the chronic misuse of these reliability coefficients. 56, 2, 81-105.) In the cross-loading conditions, we also estimated a correctly specified CFA model in which the cross-loadings were estimated. The simplest and most common way to estimate a correlation between two scales is by summing or averaging the scale items as scale scores and then taking the correlation (denoted ρSS).4 The problem with this approach is that the scores contain measurement errors, which attenuate the correlation and may cause discriminant validity issues to go undetected.5 To address this issue, the use of disattenuated or error-corrected correlations where the effect of unreliability is removed is often recommended (Edwards, 2003; J. However, two conclusions that are new to discriminant validity literature can be drawn: First, the lack of cross-loadings in the population (i.e., factorial validity) is not a strict prerequisite for discriminant validity assessment as long as the cross-loadings are modeled appropriately. If the effect of measurement error can be assumed to be negligible, even using scale score correlations can be useful as a rough check. Thus, convergent and discriminant validity are demonstrated. Evidence based on test content. The number of required model comparisons is the number of unique correlations between the variables, given by k(k−1)/2, where k is the number of factors. There’s a number of things we can do to address that question. Multitrait-Multimethod Correlation Matrix and Original Criteria for Discriminant Validity. These findings raise two important questions: (a) Why is there such diversity in the definitions? (2015) and Voorhees et al. Discriminant validity was originally presented as a set of empirical criteria that can be assessed from multitrait-multimethod (MTMM) matrices. If the estimate falls outside the interval (e.g., less than .9), then the correlation is constrained to be at the endpoint of the interval, and the model is re-estimated. As expected based on our analysis, the misused version using scale score correlation, AVE/SVSS has a smaller false positive rate because the attenuation bias in the scale score correlation worked to offset the high false positive rate of the AVE comparison. To move the field toward discriminant validity evaluation, we propose a system consisting of several cutoffs instead of a single one. The responses of the 21 available replies were all scale score correlations. Our explanation for this finding is that although χ2(merge) imposes more constraints on the model, these constraints work differently when the factors are perfectly correlated and when they are not. In general we want convergent correlations to be as high as possible and discriminant ones to be as low as possible, but there is no hard and fast rule. This scale was adopted on the basis of a discriminative validity pro cedure and from FPEPS ACT 4001 at University of Malaysia, Terengganu But as I said at the outset, in order to argue for construct validity we really need to be able to show that both of these types of validity are supported. The CIs for ρCFA were obtained from the CFAs, and for ρDPR, we used bootsrap percentile CIs, following Henseler et al. And, in many studies we simply don’t have the luxury to go adding more and more measures because it’s too costly or demanding. That’s not bad for one simple analysis. Other misuses are that only one of the two AVE values or the average of the two AVE values should be greater than the SV (Farrell, 2010; Henseler et al., 2015). Fifth, the definition does not confound the conceptually different questions of whether two measures measure different things (discriminant validity) and whether the items measure what they are supposed to measure and not something else (i.e., lack of cross-loadings in Λ, factorial validity),3 which some of the earlier definitions (categories 3 and 4 in Table 2) do. We review various definitions of and techniques for assessing discriminant validity and provide a generalized definition of discriminant validity based on the correlation between two measures after measurement error has been considered. For example, a correlation of .87 would be classified as Marginal. First, exclude all correlation pairs whose upper limit of the CI is less than .80. This phenomenon leads to a higher false positive rate because while the additional constraints contribute degrees of freedom, they contribute less misfit. First, these comparisons involve assessing a single item or scale at a time, which is incompatible with the idea that discriminant validity is a feature of a measure pair. We will now prove that the HTMT index is equivalent to the scale score correlation disattenuated with the parallel reliability coefficient. To fill this gap, various less-demanding techniques have been proposed, but few of these techniques have been thoroughly scrutinized. Lucas et al. Similarly, CICFA and CIDCR were largely unaffected and retained their performance from the tau-equivalent condition. The novel arthritis-specific Work Productivity Survey (WPS) was developed to estimate patient productivity limitations associated with arthritis within and outside the home, which is an unmet need in psoriatic arthritis (PsA). Thus, a more logical approach is to change the null hypothesis instead of adjusting the tests to be less powerful. While the nested model χ2 test is a standard tool in SEM, there are four issues that require attention when χ2(1) is applied for discriminant validity assessment. Of course, if multiple measurement occasions are possible, the CFA-based techniques can also be used to model these other sources of error (Le et al., 2009; Woehr et al., 2012), and these more complex models can then be applied with the guideline that we present next. This simpler form makes it clear that HTMT is related to the disattenuation formula (Equation 4). Equation 2 is an item-level comparison (category 2 in Table 2), where the correlation between items i and j, which are designed to measure different constructs, is compared against the implied correlation when the items depend on perfectly correlated factors but are not perfectly correlated because of measurement error. Based on this indirect evidence, we conclude that erroneous specification of the constraint is quite common in both methodological guidelines and empirical applications. View or download all content the institution has subscribed to. The techniques and the symbols that we use for them are summarized in Table 4. This assumption was also present in the original article by Campbell and Fiske (1959) that assumed a construct to be a source of variation in the items thus closely corresponding to the definition of validity by Borsboom et al. Gain insights you need with unlimited questions and unlimited responses. For example, Le et al. We demonstrate this problem in Online Supplement 1. We present a definition that does not depend on a particular model and makes it explicit that discriminant validity is a feature of a measure instead of a construct:2 Two measures intended to measure distinct constructs have discriminant validity if the absolute value of the correlation between the measures after correcting for measurement error is low enough for the measures to be regarded as measuring distinct constructs. Given our focus on single-method and one-time measurements, we address only single-administration reliability, where measurement errors are operationalized by uniqueness estimates, ignoring time and rater effects that are incalculable in these designs. The main problem that I have with this convergent-discrimination idea has to do with my use of the quotations around the terms “high” and “low” in the sentence above. The question is simple – how “high” do correlations need to be to provide evidence for convergence and how “low” do they need to be to provide evidence for discrimination? This technique proliferation causes confusion and misuse. The figure shows six measures, three that are theoretically related to the construct of self esteem and three that are thought to be related to locus of control. Reliability can be estimated in different ways, including test-retest reliability, interrater reliability and single-administration reliability,7 which each provide information on different sources of measurement error (Le et al., 2009; Schmidt et al., 2003). Establishing these different types of validity for a measure increases overall confidence that the indicator measures the concept it is intended to. Thus, while a well-fitting factor model is an important assumption (either implicitly—e.g., the various ρD—or explicitly—e.g., CFA techniques), model fit itself will not provide any information on whether either of the two empirical criteria shown in Equation 2 and Equation 3 holds.
