discriminant validity meaning

As a construct, intelligence does not exist as a separate thing we can touch or feel, so it cannot be used as an objective criterion. The meaning of a goodness of fit found for any model should be interpreted with care. “My stomach gets upset when I think about taking tests”, “My heart starts pounding fast whenever I think about results.”. The p value gives the probability of obtaining a X2 value larger than that actually obtained, given that the hypothesized model holds. The Multitrait-Multimethod Matrix (MTMM) is a formal method of measuring these two validity concepts together to determine the extent to which the instrument is meets convergent and discriminant validity measures. That is, a validity value for a variable should be higher than the correlations obtained between that variable and any other variable having neither trait nor method in common. . In attitude theory research, for example, Ostrom (1969) and Kothandapani (1971) used the method to test the utility of representing attitudes through the tripartite model consisting of affective, behavioral, and cognitive components. Not only may the neglect of construct validity lead to erroneous conclusions, but it may mask important relationships in one's research. When the measure is compared to another measure of the same type, they will be related. R. Fletcher and M. J. D. Powell, "A Rapidly Convergent Descent Method for Minimization," The Computer Journal, 6 (1963), 163-169. Discriminant validity was assessed through CFA by comparing the w 2 differences between a con-strained confirmatory factor model with an interfac-tor correlation set to 1 (indicating they are the same construct) and an unconstrained model with an inter-factor correlation set free. This test, termed congeneric in the literature, is a test of whether the three components of attitude are indeed measures of a single construct or not. The notation in the diagram corresponds to that developed below. A construct is defined as something built by mental synthesis. Arthur S. Goldberger and Otic Dudley Duncan (eds. In general, construct validity can be determined by analyzing the following six criteria for one's constructs (Bagozzi, 1976a): 1. They stressed the importance of using both discriminant and convergent validation techniques when assessing new tests. However, a number of researchers have derived criteria for various submodels. Lacking explicit, unambiguous criteria, the authors relied on arbitrary "counting procedures" to represent the proportion of times the correlation relationships were violated. There is Fisher’s (1936) classic example o… The first two are semantic criteria and refer to the internal consistency of the language used to represent a concept and the conceptual relationship between a theoretical variable and its operationalization(s), respectively. Finally, the procedure is illustrated through a reanalysis of a portion of the data of Ostrom (1969). 85-112. Discriminant validity assessment has become a generally accepted prerequisite for analyzing relationships between latent variables. For example, a test might be used to predict which engaged couples will have successful  marriages and which ones will get divorced. In the following paragraphs, a general model is derived for determining construct validity for r = 2 traits (i.e., variables) and s = 2 methods. We then assess what researchers mean by discriminant validity and synthesize this meaning as a definition. 82-83) summarize convergent and discriminant validity in terms of the pattern of correlations as follows: Four aspects bear upon the question of validity. In order to obtain an unique solution of the parameters in S ,it is necessary to have at least as many unique equations relating observable variables to the structural parameters as there are parameters. Design of Experiments > Convergent Validity and Discriminant Validity. . Omitting irrelevant constants the logarithm of the likelihood function may be written as EQUATION   (5) where N = M - 1 , M is the number of observations, log is the natural logarithm, and tr stands for the trace (c.f., Thiel, 1971, Chap. This article attempts to derive and illustrate a methodology for determining the portion of construct validity represented in criteria 4 and 5 above: convergent and discriminant validity. Furthermore, it is assumed that z is uncorrelated with x and that B is nonsingular. In particular, x1 , x2 and x3 represent three traits (variables), and x4, x5, and x6 depict three methods. The symbols, e and d, are vectors of errors of measurements in Y and X , respectively and are assumed uncorrelated with each other and the theoretical constructs. In the first place, the entries in the validity diagonal should be significantly different from zero and sufficiently large to encourage further examination of validity. Therefore, only two method factors were used and the fit of the model was X2 = 10.16 (14d.f., p = .75) which is also a good fit. convergent definition: 1. coming closer together: 2. becoming more similar: 3. coming closer together: . Specifically, Let H0 be the null hypothesis of the model under the given specifications of fixed, constrained, and free parameters. Let H0 by any specific hypothesis concerning the parametric structure of the general model and let H1 by an alternative hypothesis. Divergent or Discriminant validity Tests that constructs should have no relationship do, in fact, not have any relationship. Table 4 presents a summary of the maximum likelihood estimates for this model, table 5 summarizes the residuals, and table 6 shows the variance components due to attitude components, methods, and error. . Discriminant validity. Face validity is the mere appearance that a measure has validity. Criterion-related validity studies mean nothing at all unless the criterion is valid and reliable. The matrices Ly(p x m) and Lx(q x n) are regression matrices of y on h and x on x , respectively. . Construct validity defines how well a test or experiment measures up to its claims. The director ofHuman Resources wants to know if these three job classifications appeal to different personalitytypes. It is a systematic examination of test content to determine whether it covers a representative sample of all dimensions / domain to be measured. Those parameters in S that are not restricted are termed free parameters. . The model provides an explicit, overall X2 goodness-of-fit test, and it can be used to partition the variance due to construct, method, and error. In large samples one can then test H0 against H1. The last three criteria provide evidence for discriminant validity. Face validity is when a test appears to measure a certain criterion; it does not guarantee that the test really measures phenomena in that factor. A test created to measure depression, it must only measure that specific construct, not closely related ideals like stress or anxiety. In particular, each model would be estimated separately, and the respective X2 tests would be compared. The program also calculated an overall goodness of fit X2 test. For construct validity, the most important hypothesis to examine is whether F12 = F23 = F13 = 1 or not. Henseler, Ringle and Sarstedt (2015) show by means of a simulation study that these approaches do not reliably detect the lack of discriminant validity in commo… Discriminant Validity. External validity is usually split into two distinct types. Thomas J. Rothenberg, Efficient Estimation with a Priori Information (New Haven, Conn.: Yale University Press, 1973). Finally, the procedure is illustrated through a reanalysis of a portion of the data of Ostrom (1969). We demonstrate specific relationships that we can expect if the test is really doing its job. Typically, this will require that restrictions be placed on elements of S. In general, two classes of restrictions are possible: fixed parameters and constrained parameters. For variance-based structural equation modeling, such as partial least squares, 1. the Fornell-Larcker criterion and 2. the examination of cross-loadingsare the dominant approaches for evaluating discriminant validity. The X2 test is derived from the likelihood ratio technique, and it' tests the null hypothesis of a given model in S versus the alternative hypothesis that S is any positive definite matrix. Maximizing log L in (5) is equivalent to minimizing EQUATION   (7) J÷reskog and his colleagues have derived a procedure to minimize (7) (the details may be found in J÷reskog and van Thillo, 1972; J÷reskog, 1973; and Gruvaeus and J÷reskog, 1970). It is the relationship between a test and a criterion is usually expressed as a correlation. The dimension of S is [(p + q) x (p + q)] . In both the Ostrom (1969) and Kothandapani (1971) studies of attitudes, for example, many of the correlation patterns for discriminant validity were not satisfied. Therefore, only two method factors were used and the fit of the model was X2 = 10.16 (14d.f., p = .75) which is also a good fit. What are basic Types of Motivation: Physiological, Psychological & Social? K. G. J÷reskog and Marielle van Thillo, "LISP, EL: A General Computer Program for Estimating a Linear Structural Equation System Involving Multiple Indicators of Unmeasured Variables," Research Bulletin 72-56 (Princeton, New Jersey: Educational Testing Service, December, 1972). The procedure was illustrated using the tripartite attitude model data of Ostrom (1969). Theoretical Meaningfulness of Concepts 2. ABSTRACT - A general structural equation model is derived for determining convergent and discriminant validity. Discriminant validity, on the other hand, is the extent to which scores on a measure are not correlated with measures of variables that are conceptually distinct. The traditional method for determining construct validity has been to use the multitrait-multimethod matrix (MM) approach (Campbell and Fiske, 1959). First note that only hypothesis H4 provides a satisfactory fit in that p value for the X2 test is greater than the p = .10 rule of thumb (c.f., Lawley and Maxwell, 1971, p. 42). The X2 test is derived from the likelihood ratio technique, and it' tests the null hypothesis of a given model in S versus the alternative hypothesis that S is any positive definite matrix. (Joreskog and van Thillo, 1972, p. 8). After defining what discriminant validity means, we provide a detailed discussion of each of the techniques identified in our review. V. Kothandapani, "Validation of Feeling, Belief, and Intention to Act as Three Components of Attitude and Their Contribution to Prediction of Contraceptive Behavior," Journal of Personality and Social Psychology, 19(September, 1971), 321-333. Using a maximum likelihood estimation procedure, the model provides for an overall c2 goodness-of-fit test, and it explicitly partitions the variance due to construct, method, and error. The difference in X2 is distributed asymptotically X2 with the degrees of freedom equal to the difference between the separate degrees of freedom. . Discriminant validity and convergent validity are the two components of construct validity. Since the theoretical constructs, h and x , are not directly observed, it is necessary to form the following equations relating theoretical constructs to observable variables; Y = u + Lyh + e   (2) X = v + Lx x + d (3) FIGURE 1 A CAUSAL DIAGRAM FOR A MULTITRAIT-MULTIMETHOD MATRIX WITH THREE TRAITS AND THREE METHODS where Y' = (Y1, Y2,...,Yp) and X'  = (X1, X2,...,Xq) . Anastasi, A., & Urbina, S. (1997). intelligence) is actually measuring that construct. This page provides all possible translations of the word discriminant validity in almost any language. A third common-sense desideratum is that a variable correlate higher with an independent effort to measure the same trait than with measures designed to get at different traits which happen to employ the same method. The basis for restricting parameters may be due to prior theoretical knowledge, logical criteria, empirical evidence, or experimental design considerations. If they say ‘yes’ to both question, Can we conclude that person is anxious? In general, from the goodness-of-fit test, one may conclude that convergent and discriminant validity have been achieved for the data of Ostrom (1969) when one confines the analysis to the Thurstone, Likert, and Guttman methods. Discriminant validity is the degree to which scores on a test *do not* correlate with scores from other tests that *are not* designed to assess the same construct. If all parameters of the model are identified, the whole model is said to be identified. Then F1 = F0 and minus twice the logarithm of the likelihood ratio becomes N(F0 B F1). A number of interesting findings from table 6 deserve mention. However, a number of researchers have derived criteria for various submodels. Brian Sternthal, Alice M. Tybout, C. S. Craig, and Richard P. Bagozzi, "In Search of the Holy Grail: The Validity of the Tripartite Classification of Attitudes" (unpublished working paper), Northwestern University, 1976, Henri Theil, Principles of Econometrics (New York: Wiley, 1971). Face validity is not validity at all, because it does not offer evidence to support conclusions drawn from test scores. J÷reskog and his colleagues have derived a procedure to minimize (7) (the details may be found in J÷reskog and van Thillo, 1972; J÷reskog, 1973; and Gruvaeus and J÷reskog, 1970). In contrast, frontal theta was characterized by one low‐ variance component, low signal quality, lack of a distinct spectral peak, and mixed validity. If all of the criteria are satisfied in table 2, then one may conclude that convergent and discriminant validity have been achieved. It shows the extent to which the test scores precisely estimate an person’s current state with respects to the criterion. As developed by Campbell and Fiske (1959), the MM approach is designed to ascertain (1) the degree to which two or more attempts to measure the same concept through maximally different methods are in agreement (convergent validity) and (2) the degree to which a concept differs from other concepts (discriminant validity). TABLE 4 STANDARDIZED MAXIMUM LIKELIHOOD ESTIMATES OF PARAMETERS FOR THE DATA OF OSTROM (1969) WITH THREE METHODS (THURSTONE, LIKERT, AND GUTTMAN) AND TWO METHOD FACTORS TABLE 5 RESIDUALS FOR DATA OF OSTROM (1969) WITH THREE METHODS AND TWO METHOD FACTORS TABLE 6 PARTITIONING OF VARIANCE DUE TO ATTITUDE COMPONENT, METHOD, AND ERROR FOR THE DATA OF OSTROM (1969)--THREE METHODS AND TWO METHODS FACTORS In general, from the goodness-of-fit test, one may conclude that convergent and discriminant validity have been achieved for the data of Ostrom (1969) when one confines the analysis to the Thurstone, Likert, and Guttman methods. ), Structural Equation Models in the Social Sciences (New York: Seminar Press, 1973), pp. Lacking explicit, unambiguous criteria, the authors relied on arbitrary "counting procedures" to represent the proportion of times the correlation relationships were violated. He does not, however, treat the case of prior restrictions on the covariance matrix of disturbances including the condition of correlated measurement errors. As Joreskog and van Thillo (1972) note: Identification depends on the specification of fixed, constrained, and free parameters. C. Hsiao, "Identification for a Linear Dynamic Simultaneous Error-Schock Model" (working paper), Department of Economics, University of California, Berkeley, 1975. Example 1.A large international air carrier has collected data on employees in three different jobclassifications: 1) customer service personnel, 2) mechanics and 3) dispatchers. This branch of validity operates under the principle that tests and methods shouldn’t overlap when the constructs they are meant to measure aren’t related in theory. Posted onOctober 11, 2020December 20, 2020AuthorBalaji NiwlikarLeave a comment, Reliability_and_validity 2 by careershodh. . The discriminant validity assessment has the goal to ensure that a reflective construct has the strongest relationships with its own indicators (e.g., in comparison with than any other construct) in the PLS path model (Hair et al., 2017). Both essential elements in judging the strength of an experimental design. However, an examination of the maximum likelihood estimates reveals that the method factor due to the Guttman measure correlates unity with the other measures. Validity of a test means, What the test measures and how well it does? Building upon the MM approach, the general model represents the pattern of relationships among theoretical variables and operationalizations. In table 1, the bold face type indicates validity diagonals, heterotrait-monomethod triangles are shown as solid lines, and heterotrait-heteromethod triangles are drawn as broken lines. Domains, sections, types, etc should be fully described in advance. In-other-words there is a causal relationship between the independent and dependent variable. Not only do these procedures fail to provide objective means for determining whether one has achieved construct validity or not, but they do not indicate the degree to which operationalizations measure concepts. If they don’t, the questions might not be valid. A third category of prior information may be accommodated when data from additional samples are provided. T. Campbell and Fiske (1959) introduced an important set of logical considerations for establishing evidence of construct validity. 85-112. . validity coefficients, are fundamental for establishing validity. These equations represent the system of figure 1. After presenting the multitrait-multimethod approach to construct validity and discussing its limitations, a general model based on the analysis of covariance structures due to Joreskog (1970, 1971, 1973) was derived for determining convergent and discriminant validity. Notes for MA Psychology North Maharashtra University, INDUSTRIAL AND ORGANIZATIONAL (I/O) PSYCHOLOGY, Breaking news from SPPU- about the regular offline classes. Using a maximum likelihood estimation procedure, the model provides for an overall c2 goodness-of-fit test, and it explicitly partitions the variance due to construct, method, and error. Hypotheses HI - H4 are each tested against the most general alternative that Z is unconstrained (see discussion in the previous section). After defining what discriminant validity means, we provide a detailed discussion of each of the techniques identified in our review. Let H0 by any specific hypothesis concerning the parametric structure of the general model and let H1 by an alternative hypothesis. Discriminant validity, as a subset of construct validity, will assure researchers that the test, assessment, or method used in evaluating the non-numerical construct is appropriate and applicable in the given context.

Bagozzi, "Construct Validity in Consumer Research" (unpublished working paper), School of Business Administration, University of California, Berkeley, 1976a. The hypothesis may be tested by observing the difference between either hypotheses H1 and H2 or H3 and H4, depending on whether one assumes parallel forms or not. In both the Ostrom (1969) and Kothandapani (1971) studies of attitudes, for example, many of the correlation patterns for discriminant validity were not satisfied. The tests for parallel measures hypothesize that the components each have equal true score variances and equal error variances. These appearances can help to motivate test takers by showing relevance. A computer program, LISP, EL, exists for estimating the parameters of the general model (J÷reskog and van Thillo, 1972). V. J. Geraci, "Simultaneous Equation Models with Measurement Error" (unpublished doctoral dissertation), Department of Economics, University of Wisconsin, July, 1974. validity coefficients, are fundamental for establishing validity. When one cannot accept the hypothesis that the three components are congeneric, method factors should be introduced, and the following structural equation system should be solved: EQUATION TABLE 3 OSTROM'S (1969) MM MATRIX DATA TESTED FOR CONGENERIC AND PARALLEL HYPOTHESES-- THURSTONE, LIKERT, AND GUTTMAN METHODS ONLY These equations represent the system of figure 1. What are the important Perspectives of Psychology? The solution of these equations using the methods described above yields a goodness-of-fit X2 = 5.03 (12d.f., p = .96) which represents a very good fit.

Briefly, the minimization method is based on the iterative procedure of Fletcher and Powell (1963). A general structural equation model is derived for determining convergent and discriminant validity. Traditionally, content validity evidence has been of greatest concern in educational testing. Discriminant validity assessment has become a generally accepted prerequisite for analyzing relationships between latent variables.

Finally, we compare the techniques in a comprehensive Monte Carlo simulation. As we’ve already seen in other articles, there are four types of validity: content validity, predictive validity, concurrent validity, and construct validity.
