Methods : A large American sample ( N = 2732) was used. 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 means that two latent variables that represent different theoretical concepts are statistically different. Another alternative is to do a nested model comparison against a model where The criteria for discriminant validity are well summarised by Farrell ( p. 324): “Discriminant validity is the extent to which latent variable A discriminates from other latent variables (e.g., B, C, D). In some cases, the original correlation estimate may already be greater than the cutoff, making it redundant to fit a … For variance-based structural equation modeling, such as partial least squares, the Fornell-Larcker criterion and the examination of cross-loadings are the dominant approaches for evaluating discriminant validity. Technically, discriminant validity requires that“atestnot correlatetoohighlywithmeasuresfromwhich it is supposed to differ” (Campbell 1960, p. 548). ADANCO is a user-friendly software for composite-based structural equation modeling and confirmatory composite analysis. h�b```f``_���� � ̀ �@1v��'}�NY$�x���*01�0KAhj�g�U�K^�%�g���f���-�\O�_o��Xd̺�c�PC�j�Q.�W�fI/>�D4j��*ȸy�D���L����b&�7���ٱ6�իd٩n��Ǿ�����Rq�c×����D�9~�w�E$���s��Z>nec��^vW�Ý�^^ٕ֭t4�w�N+㥗��oX�t����E�� �C͌��wN^������9�\����T/d��cW���W^N��ٖ����b����R�{E�����̍:�z��震�N@ö�e]����[{��x*6�;k����Yf�D���3]s��q�`�Ե���K/, �+m�ż��h)����^d����� \R�����4 �vq��M�fPa TRUE.

")if (length(lavNames(object,"lv.y"))>0)warning("The model has at least one endogenous latent variable (",paste(lavNames(object,"lv.y"),collapse=", "),"). Discriminant validity assessment has become a generally accepted prerequisite for analyzing relationships between latent variables. 0000039803 00000 n Hence the measurement model is free from the redundant items and the discriminant validity is achieved (Zainudin, 2015). The two scales measure theoretically different constructs. 0000020895 00000 n An investigation of the factor structure and convergent and discriminant validity of the five-factor model rating form ... the structural validity of the domain-level assessment has not yet been evaluated. 0000004730 00000 n <]/Prev 1487003>> This rule is known as Fornell–Larcker criterion. Discriminant validity means that a latent variable is able to account for more variance in the observed variables associated with it than a) measurement error or similar external, unmeasured influences; or b) other constructs within the conceptual framework. In their widely cited article on tests to evaluate structural equation models, Fornell and Larcker suggest that discriminant validity is established if a latent variable accounts for more variance in its associated indicator variables than it shares with other constructs in the same model.

Since Campbell and Fiske (1959) defined convergent validity and discriminant validity, the tests for convergent validity and discriminant validity have evolved from checking the “high” and “low” correlation coefficients in the multitrait-multimethod context to specific rules of thumbs suggested by Fornell and Larcker (1981) in a multitrait-monomethod context. The typical purpose of this test is to demonstrate that the estimated factor correlation is well below the cutoff and a significant chi^2 statistic thus indicates support for discriminant validity.
