Designing and validating a measure of moral judgment: Stage preference and stage consistency approaches.

The Defining Issues Test (DIT) of moral judgment is discussed in light of the recent challenge by G. Lind (1995) with the Moral Judgment Test (MJT), which is widely used in Europe. The 2 tests represent alternative methods as well as support different conclusions about moral judgment. The key difference is a stage-consistency (MJT) vs. a stage-preference (DIT) approach. Construct validity is defined in terms of 7 types of studies, and the approaches are compared. The stage-preference approach systematically outperforms the stage-consistency approach. Benchmarking by using classic studies in moral judgment illustrates an empirical, multistudy, quantitative approach to moral judgment research.
