Evidence

Though the correlation of the I-CG to other constructs and methods was not perfect, the results did closely meet most of Campbell and Fiske’s (1959) guidelines for the MTMM approach. In fact, the I-CG met, and in some cases exceeded, the MTMM criteria of the more established measures of RWA and TF with the sample used in the current study. — Sherman A. Lee, Chelsea A.
