Discriminant Validity. 82-83) summarize convergent and discriminant validity in terms of the pattern of correlations as follows: Four aspects bear upon the question of validity. The difference in X2 is distributed asymptotically X2 with the degrees of freedom equal to the difference between the separate degrees of freedom. External validity is usually split into two distinct types. Example 2. Finally, the procedure is illustrated through a reanalysis of a portion of the data of Ostrom (1969). https://www.simplypsychology.org/validity.html#ext, https://en.wikipedia.org/wiki/Validity_(statistics), Categoriesnotifications, Psychological Testing: Theory, Research MethodologyTags. Building upon the MM approach, the general model represents the pattern of relationships among theoretical variables and operationalizations. The goal in such an analysis should be to set up a hierarchy of hypotheses such that each is a special case of another. This valorization procedure used in test design to measure how well person mastered the skill. FYBA Psychology (SPPU) Syllabus wise Notes, Psychometrics: The Science Of Psychological Assessment. The model is based on Joreskog's (1970, 1973) structural analysis of covariance matrices and builds upon the author's use of the method for sets of congeneric tests and multitrait-multimethod data (c.f., Joreskog, 1971; 1974). Roger M. Heeler and Michael L. Ray, "Measure Validation in Marketing," Journal of Marketing Research, 9(November, 1972), 361-370. Anastasi, A., & Urbina, S. (1997). For example, a test of intelligence might be influenced by reading comprehension, test anxiety, or illness. For example, self-esteem is a general attitude toward the self that is fairly stable over time. The model developed below can be used in these cases. Campbell and Fiske (1959, pp. 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. Further, neither Fisher nor Geraci deal with dynamic models allowing measurement error. Testing for this type of validity requires that you essentially ask your sample similar questions that are designed to provide you with expected answers. Finally, the procedure is illustrated through a reanalysis of a portion of the data of Ostrom (1969). Equation (1) represents the set of all possible linear relationships among the true independent and dependent variables. Derived from the common feature shared by directly observable behavior. THE EXAMPLE OF THE ATTITUDE CONSTRUCT In order to illustrate the structural equation approach to construct validity, consider the study conducted by Ostrom (1969). Figure 1 presents a causal diagram for a multitrait-multimethod matrix such as shown in table 1. Omitting irrelevant constants the logarithm of the likelihood function may be written as, 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. Second, a validity diagonal value should be higher than the values lying in its column and row in the hetero-trait-heteromethod triangles. A third category of prior information may be accommodated when data from additional samples are provided. To establish discriminant validity, you need to show that measures that should not be related are in reality notrelated. He does not, however, treat the case of prior restrictions on the covariance matrix of disturbances including the condition of correlated measurement errors. In quantitative research, you have to consider the reliability and validity of your methods and measurements.. Validity tells you how accurately a method measures something. K. G. J÷reskog, "A General Method for Analysis of Co-variance Structures," Biometrika, 57 (1970), 239-251. K. G. J÷reskog, "Analyzing Psychological Data by Structural Analysis of Covariance Matrices," in D. H. Krantz, R. D. Luce, R. C. Atkinson, and P. Suppes (eds. Most of the psychological test use this validity. What Is Validity & Its Definition, History, Types ? Robert Böhm, RWTH Aachen University 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. . Maximizing log L in (5) is equivalent to minimizing. External validity concerns the extent to which the (internally valid) results of a study can be held to be true for other cases, for example to different people, places or times. 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. The difference in X2 is distributed asymptotically X2 with the degrees of freedom equal to the difference between the separate degrees of freedom. 9+ Discriminant Validity Examples. Since X212= 99.11 and X212 = 99.01 in table 3, one must reject the hypothesis of parallel measures. revealed discriminant validity, meaning that the total ECOHIS score is capable of distinguishing children with and without dental caries. MULTITRAIT-MULTIMETHOD MATRIX OF CORRELATIONS FROM OSTROM (1969). A computer program, LISP, EL, exists for estimating the parameters of the general model (J÷reskog and van Thillo, 1972). In addition, the sample variance-covariance matrix is, where Z= (Y', X' ) is the maximum likelihood estimate of the mean vector of observations and Za are the individual instances of Z. Convergent validity is the degree to which the same aspect of a single phenomenon or construct can be accessed and quantified by different models, whereas discriminant validity is the capacity of a model to measure different aspects of a single target phenomenon from those measured by related models. Convergent Validity is a sub-type of construct validity.Construct validity means that a test designed to measure a particular construct (i.e. First consider the case when the alternative hypothesis H1 is that S is any positive definite matrix. . Validity of an assessment is the degree to which it measures what it is supposed to measure. ., zm) which may be  related compactly in the following system of linear structural relations (c.f., J÷reskog and van Thillo, 1972): In this equation, B(m x m) and G(m x n) are matrices of coefficient parameters, and z' = (z1, z2, . Roger M. Heeler and Michael L. Ray, "Measure Validation in Marketing," Journal of Marketing Research, 9(November, 1972), 361-370. All of these tests should have construct validity. 85-112. The MM approach determines convergent and discriminant validity through an analysis of the pattern of correlations among two or more traits measured by two or more method. Without a valid design, valid scientific deductions cannot be drawn. ., zm) is a random vector of disturbances (i.e., errors in equations). 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). These equations represent the system of figure 1. The notation in the diagram corresponds to that developed below. – Validity requires evidence in order to justify conclusions. Criterion validity evidence tells us just how well a test corresponds with a particular criterion. If we have discriminant validity, the relationship between measures from different constr… Each employee is administered a battery of psychological test which include measuresof interest in outdoor activity, sociability and conservativeness. Reliability was assessed with Cronbach's alpha coefficients and construction reliability. Advances in Consumer Research Volume 4, 1977    Pages 11-18 CONVERGENT AND DISCRIMINANT VALIDITY BY ANALYSIS OF COVARIANCE STRUCTURES: THE CASE OF THE AFFECTIVE, BEHAVIORAL, AND COGNITIVE COMPONENTS OF ATTITUDE Richard P. Bagozzi, University of California, Berkeley ABSTRACT - A general structural equation model is derived for determining convergent and discriminant validity. A criterion is the standard against which the test is compared. The procedure is illustrated on data from Ostrom's (1969) study of the affective, behavioral, and cognitive components of attitude. the fact of having legal force, or being legally acceptable: Election observers challenged the validity of the vote. . 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. . Lacking explicit, unambiguous criteria, the authors relied on arbitrary "counting procedures" to represent the proportion of times the correlation relationships were violated. Observational Meaningfulness of Concepts, 3. © 2021 Association for Consumer Research, The Journal of the Association for Consumer Research (JACR). Your email address will not be published. Fisher (1966) discusses the identification problem for the general model of multiple independent and dependent variables (i.e., endogenous and exogenous variables) but does not deal with the case of multiple operationalizations of theoretical constructs. CHILDREN’S PERSONALITY QUESTIONNAIRE (CPQ). and Discriminant Validity Evidence T he previous chapter presented conceptual perspectives on validity, and it summarized the types of evidence used to gauge construct validity. Second, note that the Likert scales contain a considerable amount of method variance, and the Thurstone and Guttman measures produce significantly less method variance. In the following paragraphs, a general model is derived for determining construct validity for r = 2 traits (i.e., variables) and s = 2 methods. Those parameters in S that are not restricted are termed free parameters. In addition, u = E(Y) and v = E(X). When a model is identified, one can usually find consistent estimates of all parameters (pp. It will typically involve syntactical considerations in one's theoretical structure as well as empirical testing (for a discussion of these topics, see Bagozzi, 1976b). The conclusion section is structured as a set of guidelines for applied researchers and presents two techniques. A fourth desideratum is that the same pattern of trait interrelationship be shown in all of the heterotrait triangles of both the mono-method and heteromethod blocks. In particular, each model would be estimated separately, and the respective X2 tests would be compared. More specifically, validity refers to the degree to which a certain inference or interpretation based on a test is appropriate. The TTM holds that individuals progress through qualitatively distinct stages when changing be-haviors such as smoking cessation (Prochaska & Velicer, 1997). 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. and discriminant validity of the Decisional Balance Scale of the Transtheoretical Model (TTM). For a given variable, this involves comparing its values in the validity diagonals with its values in the heterotrait-monomethod triangles. Construct validity refers to how well a test or tool measures the construct that it was designed to measure. 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. 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: OSTROM'S (1969) MM MATRIX DATA TESTED FOR CONGENERIC AND PARALLEL HYPOTHESES-- THURSTONE, LIKERT, AND GUTTMAN METHODS ONLY. Third, the Guttman scales and, to a somewhat lesser extent, the Thurstone scales show relatively high error components. Specifically, Let H0 be the null hypothesis of the model under the given specifications of fixed, constrained, and free parameters. 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). 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). An empirical analysis of nomological validity may be found in Sternthal, et al (1976). When a measure correlates well with other tests believed to measure the same construct, convergent evidence for validity is obtained. Construct underrepresentation describes the failure to capture important components of a construct. As shown in the right-hand portion of table 3, the tests for parallel measures are represented by the differences between H1 and H3 or H2 and H4. Also, to be consistent with the computer program developed by Joreskog and van Thillo (1972), the following specifications are made: B(4H4) = I , G (4x4) = I, and z = 0 .] The validity of the design of experimental research studies is a central part of the scientific method, and a concern of research ethics. The forecasting function of tests is actually a type or form of criterion validity evidence known as predictive validity evidence. The director ofHuman Resources wants to know if these three job classifications appeal to different personalitytypes. Criteria 4 and 5 are the traditional objects of the MM approach. Supplementary procedure to establish content validity should do analysis of types of errors. It shows that the measure does not include superfluous items and that the test measures something distinct from other tests. . By means of a simulation study, we show … C. Hsiao, "Identification and Estimation of Simultaneous Equation Models with Measurement Error," International Economic Review (forthcoming). Thomas J. Rothenberg, Efficient Estimation with a Priori Information (New Haven, Conn.: Yale University Press, 1973). 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 traditional method for determining construct validity has been to use the multitrait-multimethod matrix (MM) approach (Campbell and Fiske, 1959). Face validity is the mere appearance that a measure has validity. 82-83) summarize convergent and discriminant validity in terms of the pattern of correlations as follows: Four aspects bear upon the question of validity. The top part of the figure shows our theoretically expected relationships among the four items. As we’ve already seen in other articles, there are four types of validity: content validity, predictive validity, concurrent validity, and construct validity.

Franklin M. Fisher, The Identification Problem in Econometrics (New York: McGraw-Hill, 1966). Then minus twice the logarithm of the likelihood ratio is NF0 where F0 is the minimum value of F. If the model holds, this is distributed, in large samples, as X2 with d = 1/2(p+q)(p+q+l) - t degrees of freedom, where, as before, t is the total number of independent parameters estimated under H0. K. G. J÷reskog, "A General Method for Estimating a Linear Structural Equation System," in A. S. Goldberger and O. D. Duncan (eds. Nomological Validity 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. However, a number of researchers have derived criteria for various submodels. 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). Second, a validity diagonal value should be higher than the values lying in its column and row in the hetero-trait-heteromethod triangles. (adsbygoogle = window.adsbygoogle || []).push({});
. The third criterion is a strictly empirical one designed to determine the degree of internal consistency and single factoredness of one's operationalizations. ), Structural Equation Models in the Social Sciences (New York: Seminar Press, 1973), pp. Rothenberg (1973) discusses a way of finding the joint probability function for multiple samples and the corresponding estimation procedures. THE DISCRIMINANT VALIDITY OF ENTREPRENEURIAL PASSION MELISSA S. CARDON Pace University Lubin School of Business 861 Bedford Rd; Pleasantville NY 10570 CHRISTOPHER E. STEVENS Gonzaga University ABSTRACT We conducted two studies to develop and test a multi-dimensional measure of entrepreneurial passion. Arthur S. Goldberger and Otic Dudley Duncan (eds. 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. Membership in ACR is relatively inexpensive, but brings significant benefits to its members. Geraci (1974) derives a number of special cases of the most general model including the determination of measurement error in certain instances. The evidence in table 3 indicates that a decision as to construct validity must be temporarily postponed since X23 = 16.47 and X23 = 16.37. Not only may the neglect of construct validity lead to erroneous conclusions, but it may mask important relationships in one's research. As a result, the MM approach cannot be easily used to compare findings across populations, time, and settings, nor can it be readily used to diagnose why one's constructs or measures are fallible. The general identification problem for a system of multiple independent and dependent variables and multiple operationalizations has not been solved. Convergent validity tests that constructs that are expected to be related are, in fact, related. The groups (children with and without caries) in the selected studies were compared using the effect size, which was determined through the mean + standard deviation values of the ECOHIS scores (outcome variable). However, an examination of the maximum likelihood estimates reveals that the method factor due to the Guttman measure correlates unity with the other measures. For example- measures of intelligence, love, curiosity, or mental health. If they don’t, the questions might not be valid. (The original correlation matrix from Ostrom (1969) may be found at the end of the article). For example, table 1, which is adapted from Campbell and Fiske (1959, p. 82), presents a typical MM matrix where three traits (A,B,C,) are each measured by three methods (1,2,3). minant validity and synthesize this meaning as a definition. The most interesting hypotheses are those based on HI - H4 , however. What does the criterion mean? This requirement is evidence of convergent validity. Let F0 be the minimum of F under H1. Discriminant validity helps to establish construct validity by demonstrating that the construct you are interested in (e.g., anger) is different from other constructs that might be present in your study (e.g., depression). The SAT/ GRE, including its quantitative and verbal subtests, is the predictor variable, and the college grade point average (GPA) is the criterion. Unfortunately, due to certain ambiguities and a lack of explicit objective measures for determining validity in the MM approach, only "minimal support" was found for construct validity. 3-4). 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. Psychological testing (7th ed.). . Next, a general model following Joreskog's (c.f., 1970, 1971) procedures is presented. For example, self-esteem is a general attitude toward the self that is fairly stable over time. Yuwei Jiang, Hong Kong Polytechic University Although an inspection of the MM matrix in Ostrom (1969) clearly shows that convergent validity has been achieved, the degree of discriminant validity is not easily inferred from the MM matrix since some patterns of correlations do not satisfy the three discriminant validity criteria enumerated in table 2. Under a given specification, a given structure Ly, Lx, B, G, F, y, qd, qe generates one and only one S but there may be several structures generating the same S. If two or more structures generate the same S, the structures are said to be equivalent. 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. When the measure is compared to another measure of the same type, they will be related. Face validity is not validity at all, because it does not offer evidence to support conclusions drawn from test scores. G. T. Gruvaeus and K. G. Joreskog, "A Computer Program for Minimizing a Function of Several Variables," Research Bulletin 70-14 (Princeton, New Jersey: Educational Testing Service, 1970). In large samples one can then test H0 against H1. Convergent and discriminant validity were also examined. Campbell and Fiske (1959) introduced the concept of discriminant validity within their discussion on evaluating test validity. In order to determine construct validity using the analysis of covariance procedures, it is useful to analyze the data in two stages. Donald T. Campbell and Donald W. Fiske, "Convergent and Discriminant Validation by the Multitrait-Multimethod Matrix," Psychological Bulletin, 56(1959), 81-105. 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. The tests for parallel measures hypothesize that the components each have equal true score variances and equal error variances. Two types of Construct validity by Campbell & Fiske (1959). Next, a general model following Joreskog's (c.f., 1970, 1971) procedures is presented. Items, statements, or question should be reasonably related to the perceived purpose of the test. Error terms are shown as e1 - e6 and d1 - d3. There are also other methods to test the convergent and discriminant validity. The model developed below can be used in these cases. If all parameters of the model are identified, the whole model is said to be identified. 1-56. If research reveals that a test’s validity coef- Let H0 by any specific hypothesis concerning the parametric structure of the general model and let H1 by an alternative hypothesis. of construct validity including both the discriminant validity (loading of at least 0.40, no cross-loading of items above 0.40) and convergent validity (eigenvalues of 1, loading of at least 0.40, items that load on posited constructs) (Straub et al., 2004). Donald T. Campbell and Donald W. Fiske, "Convergent and Discriminant Validation by the Multitrait-Multimethod Matrix," Psychological Bulletin, 56(1959), 81-105.

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. Here, however, two of the items are thought to reflect the construct of self esteem while the other two are thought to reflect locus of control. ABSTRACT - A general structural equation model is derived for determining convergent and discriminant validity. A MULTITRAIT-MULTIMETHOD MATRIX FOR THREE TRAITS AND THREE METHODS. Finally, nomological validity is the degree to which predictions from a formal theoretical network containing the concept under scrutiny are confirmed (Campbell, 1960). Face validity is simplest form of validity. Since the X2 test depends directly on the sample size, a sufficiently large sample could be achieved which would cause one to reject virtually any model. Taking attitudes as an example, A, B, and C might depict affective, behavioral, and cognitive components, respectively, while methods 1, 2, and 3 might represent Thurstone, Likert, and Guttman scales, respectively. Franklin M. Fisher, The Identification Problem in Econometrics (New York: McGraw-Hill, 1966). We show that a test measures the same things as other tests used for the same purpose. The Likert method contains relatively small error variance. 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). William D. Perreault, Jr., Atlanta, GA : Association for Consumer Research, Pages: 11-18. Tests that constructs that are expected to be related are, in fact, related. Estimation of Parameters and the Goodness-of-fit Test, The estimation of parameters for the general model may be conveniently accomplished using the maximum likelihood procedure. Content Validity can be appropriate for Educational test, Achievement test, Employee selection and Employee Evaluation Classification. Divergent or Discriminant validity Tests that constructs should have no relationship do, in fact, not have any relationship. James R. Bettman, Noel Capon, and Richard J. Lutz, "Multiattribute Measurement Models and Multiattribute Attitude Theory: A Test of Construct Validity," Journal of Consumer Research, l(March, 1975), 1-15. For example, if discriminant validity is high, scores on a test designed to assess aggressiveness should not be positively correlated with scores from tests designed to assess intelligence. The p value gives the probability of obtaining a X2 value larger than that actually obtained, given that the hypothesized model holds.
