The DOG Scale

Abstract. Since the 1960s Rokeach's conception and measurement of dogmatism has dominated the landscape of dogmatism research. In 1996, Altemeyer proposed a new conception of dogmatism, suggesting that it is best defined as an unchangeable and unjustified certainty in one's beliefs. This conception was operationalized in the form of the DOG Scale with validity evidence generally coming in the form of relationships between the measure and several criterion-related variables. The present study assessed the factorial validity of the measure and tested for convergent and discriminant validity. Criterion-related validity evidence was also reconsidered. The DOG Scale demonstrated reasonable factorial, discriminant, convergent, and criterion-related validity, providing additional support for the measure's construct validity.
