Development and Validation of the Humboldt Idealism Questionnaire

Idealism is defined as believing that desirable consequences can, with the “right” action, always be obtained. This involves decreasing the amount of negative outcomes and increasing the amount of positive outcomes. Due to the lack of a reliable and valid existing measure of idealism, our goal was to create a psychometrically sound scale. Morality and justice are two important domains that were addressed during item creation. The HIQ was compared to the Global Belief in a Just World Scale in order to establish criterion validity; the short form of the Marlowe-Crowne Social Desirability Scale was used for discriminant validity.
