Describing and testing an intermediate concept measure of adolescent moral thinking

This paper describes the development and preliminary testing of an intermediate concept measure (ICM) of moral thinking for adolescent populations. First proposed by Rest and Narvaez (1994), intermediate concepts are described as more context specific than moral stages defined within the Kohlberg tradition, but are more abstract than assessments of codes of conduct. The process of developing the adolescent ICM is described and data are presented to provide initial support for the measure. Results indicate that the adolescent ICM can distinguish age educational groups across high school and individuals who are acting out in school achieved significantly lower scores than all other students. In addition, ICM scores are related to Defining Issues Test scores providing preliminary support for the claim that both measures assess the moral domain. Coupled with the respectable psychometric properties of the measure, these findings support the adolescent ICM as a measure of moral thinking in adolescent populations and as a potential outcome measure for character education programmes.
