Rokeach Dogmatism Scale
a 66-item scale developed in 1960 to measure individual differences in openness or closedness of belief systems (i.e., dogmatism) across several continua, such as “isolation and differentiation between belief and nonbelief systems” and “interrelations among primitive, intermediate, and peripheral beliefs.” Some studies have found the scale more useful in assessing “general authoritarianism” and “general intolerance.” [Milton Rokeach (1918–1988), U.S. psychologist]
