Are authoritarianism and dogmatism parts of the same underlying variable, or are they discriminable entities? To answer this and other questions, the F and D Scales were administered to 1239 Ss in New York, Michigan, and Louisiana. The F and D item intercorrelations were factor analyzed with the principal axes method and oblique proequamax rotations. The F and D items for the most part were loaded on different factors, even though the factors and the F and D total scores were positively correlated. Factor analysis of the correlations among the 10 oblique 1st-order factors yielded 3 2nd-order factors, which were interpreted as Dogmatism, Fascistic Authoritarianism, and Authoritarian Aggression and Submission. The F and D Scales thus seem to be factorially discriminable, even though both are measures of authoritarianism. (22 ref.) (PsycINFO Database Record (c) 2016 APA, all rights reserved)
