A means of transforming multitrait-multimethod (MTMM) matrices into a classical multiple group factor analysis is outlined. A reanalysis of two numerical illustrations shows that the classical procedure yields results similar to those reached by D. N. Jackson's (1975) two-step procedure for analysis of MTMM matrices.

The composite direct-product model for the multitrait-multimethod (MTMM) matrix is reparamaterized as a second-order factor analysis model. This process facilitates the use of widely available computer programs--LISREL and LISCOMP--for fitting the model. If bounds on phi and theta are not imposed to avoid inadmissible values, convergence problems…

The construct validity of 14 measures used in college faculty personnel decisions was evaluated through a multitrait-multimethod matrix for data from 89 faculty members in 7 departments. The three-pronged model of teaching, research, and service was not validated. Exploratory factor analysis identified five or six behavior domains for evaluation.…
