title: Brief Moral Decision-Making Questionnaire: A Rasch-derived short form of the Greene dilemmas.
abstract: In this study, we developed the Brief Moral Decision-Making Questionnaire (BrMoD) as a standardized brief form of the dilemmas compiled by Greene and colleagues (Greene, Sommerville, Nystrom, Darley, & Cohen, 2001). An initial Rasch analysis was conducted over responses to 60 dilemmas to retain the most appropriate items. The psychometric properties of the 32-item brief instrument were determined in a community sample of 133 individuals using analyses from both the Rasch model and the classical test theory. The BrMoD scores showed appropriate reliability and construct validity. Differences between dilemma categories proposed by Greene et al. were observed in the BrMoD by measuring the difficulty of decisions and response times of the participants. In addition, there was no differential item functioning by the demographic variables. Therefore, the BrMoD is a good tool for assessing moral decision making in research or professional fields.
