Development and validation of a measure to assess moral reasoning in Singapore secondary school students

This study presents the development and validation of the Moral Reasoning Questionnaire (MRQ) to assess students' moral reasoning in Singapore secondary schools. Anchored in Kohlberg's Theory of Moral Development, the MRQ comprises items presenting moral dilemmas that integrate prosocial, anti-social and social pressure elements within situations that should be familiar to most students. The MRQ was developed and validated in a series of stages including the use of expert reviews, cognitive interviews and methods based on latent trait measurement models.
