Testing Evidenceof Construct Validity
The Multitrait—Multimethod Model
The application illustrated in this chapter uses confirmatory factor analysis (CFA) procedures to test hypotheses bearing on construct validity. Specifically, hypotheses are tested within the framework of a multitrait—multimethod (MTMM) design by which multiple traits are measured by multiple methods. Following from the seminal work of Campbell and Fiske (1959), construct validity research typically focuses on the extent to which data exhibit evidence of (a) convergent validity, the extent to which different assessment methods concur in their measurement of the same trait (i.e., construct; ideally, these values should be moderately high); (b) discriminant validity, ...
