Consider the most general model consisting of a random vector of true (i.e., measured without error) dependent variables h' = (hl,h2,...,hn) and true independent variables z' = (z1, z2, . In both the Ostrom (1969) and Kothandapani (1971) studies of attitudes, for example, many of the correlation patterns for discriminant validity were not satisfied. 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. Under H0 this is distributed approximately as X2 with degrees of freedom equal to the difference in number of independent parameters estimated under H1 and H0. Results: Based on the results of the PCA and consideration of the meaning of our items, a three-factor solution, explaining 60.38% of the variance, was identified. By the mid-1950s, researchers / investigators concluded that no clear criteria existed for most of the social and psychological characteristics they wanted to measure. It makes use of the first-order derivatives and large sample approximations to the elements of the matrix of second-order derivatives to achieve minimization. The dimension of S is [(p + q) x (p + q)] . Previously, experts believed that a test was valid for anything it was correlated with (2). The third criterion is a strictly empirical one designed to determine the degree of internal consistency and single factoredness of one's operationalizations. By means of a simulation study, we show … CRITERIA FOR CONVERGENT AND DISCRIMINANT VALIDITY IN THE CAMPBELL AND FISKE MULTITRAIT MULTIMETHOD MATRIX (THREE TRAITS AND THREE METHODS). Discriminant Validity. Becoming an Association for Consumer Research member is simple. Traditionally, content validity evidence has been of greatest concern in educational testing. . Content validity establishment should consider the adequacy of representation of the conceptual domain the test is designed to cover. Specifically, Let H0 be the null hypothesis of the model under the given specifications of fixed, constrained, and free parameters. Those correlations, sometimes called . For example, any school / college test will have this face validity. Theoretical entities, not directly observed. He does not, however, treat the case of prior restrictions on the covariance matrix of disturbances including the condition of correlated measurement errors. 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. which represent the model due to attitude components and measurement error only (termed the congeneric model): Four hypotheses can be derived from this system of equations: Table 3 presents the results of hypotheses H1 - H4 applied to the data of Ostrom (1969). where Y' = (Y1, Y2,...,Yp) and X' = (X1, X2,...,Xq) . The validity of the design of experimental research studies is a central part of the scientific method, and a concern of research ethics. Construct validity is determined through an overall c2 goodness-of-fit test, and the variance due to constructs, methods, and error is partitioned through the model. 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. Campbell and Fiske (1959) introduced the concept of discriminant validity within their discussion on evaluating test validity. For example, many students do poorly on tests because of anxiety or reading problems
Estimating and Evaluating Convergent and Discriminant Validity Evidence 257 correlated with those crucial variables, test developers and test users gain increased confidence in the test. A number of interesting findings from table 6 deserve mention. ), Contemporary Developments in Mathematical Psychology, Vol. Geraci (1974) derives a number of special cases of the most general model including the determination of measurement error in certain instances.
