The purpose of the study was to investigate the effect of specified variation in dilemma content on the relationship among ethical attitude, political attitude, moral development and dilemma action choice. The moral development and action choice scores of individuals who differed in ethical attitude or political attitude were compared for two types of dilemmas, the Defining Issues Test dilemmas and alternate dilemmas, differing in terms of the action supported by authority. Measures of ethical attitude, political attitude and moral development were administered to 68 high school subjects and 35 university subjects. Results of multivariate analysis of variance repeated measures showed that moral development and action choice scores of subjects who differed in ethical attitude or political attitude did not vary for the two dilemma types. Ethical attitude was found to be related to moral development scores for both the Defining Issues Test and Alternate Dilemmas Test, but only to university subjects' action choice scores on the Defining Issues Test. Political attitude was found to be related to only university subjects' action choice scores on the Defining Issues Test. Stepwise regression analysis indicated that the D Index was the best predictor of the Defining Issues Test action choice scores for the high school sample and political attitude was the best predictor for the university sample. Limitations and implications of this research are discussed. / Education, Faculty of / Graduate
