Political identification and the defining issues test: reevaluating an old hypothesis.

Research on the association between the development of moral judgment (as measured by the Defining Issues Test [DIT]; J. R. Rest, 1979) and political attitudes has demonstrated that these factors are often reliably related. N. Emler (1987, 1990) and colleagues have asserted that DIT scores actually measure test-takers' political identity rather than their developmental level. To test this claim, these researchers have designed "faking studies" in which respondents are asked to complete the DIT as if they were of a particular political orientation, regardless of their real political views. These faking studies have yielded contradictory conclusions, whereas tests of the incremental validity of the DIT have provided some evidence for its empirical distinctiveness. In the present study, the authors reexamined this issue by pitting scores on the DIT, Version 2 (DIT-2; J. R. Rest, D. Narvaez, S. J. Thoma, & M. J. Bebeau, 1999) against several more concrete measures of political identification in several predictive models of attitudes toward human rights and civil liberties. DIT-2 scores and political identification emerged as significant predictors in nearly all regression analyses.
