Abstract

Measurement validation in consumer research is ideally performed within the context of a multi-trait multi-method matrix (MTMM). While statistically well developed, this approach has several shortcomings that limit its domain of application: (1) the requirement for sufficiently unrelated latent variables that can be measured with the same methods, (2) the requirement for conceptually different methods to disambiguate trait from methods, and most seriously (3) the difficulty in identifying a more valid over a less valid method. We compare the MTMM approach to experiment-based calibration, an alternative framework for validating those latent variables that can be externally manipulated. We show how calibration lets researchers make distinctions between even closely related measurement methods, dispenses with the need for unrelated latent variables, and enables optimization of the measurement evaluation procedure itself. Calibration can be an important part of an integrative validity argument in consumer research and, more broadly, across the social sciences.
