Coenders, Germa; Saris, Willem E. – Structural Equation Modeling, 2000
Provides alternatives to the definitions of additive and multiplicative method effects in multitrait-multimethod data given by D. Campbell and E. O'Connell (1967). The alternative definitions can be formulated by means of constraints in the parameters of the correlated uniqueness model (H. Marsh, 1989). (SLD)

Corten, Irmgard W.; Saris, Willem E.; Coenders, Germa; van der Veld, William; Aalberts, Chris E.; Kornelis, Charles – Structural Equation Modeling, 2002
Compared different models suggested for the analysis of multitrait multimethod (MTMM) experiments for their fit to 87 data sets collected in the United States. The fit of models based on polychoric correlations is much worse than the fit of models based on product moment correlations, but in both cases a model that assumes additive method effects…
