A comparison of four measures of moral reasoning.

Kohlberg's Moral Judgment Scale, Gilligan et al.'s Sexual Moral Judgment Scale, Maitland and Goldman's Objective Moral Judgment Scale, and Hogan's Maturity of Moral Judgment Scale, were examined for reliability and inter-scale relationships. All measures except the Objective Moral Judgment Scale had good reliabilities. The obtained relations between the Moral Judgment Scale and the Sexual Moral Judgment Scale replicated previous research. The Objective Moral Judgment Scale was not found to validly assess the Kohlberg stages. The Maturity of Moral Judgment Scale scores were strongly related to the subjects's classification on the Kohlberg stages, and the scale appears to offer a reliable, quickly scored, and valid index of mature thought, although the scale's continuous scores do not permit clear stage classification.
