Abstract
This article presents a longitudinal-sequential analysis of the developmental and reciprocal relationships between self-reported delinquency and moral reasoning (as measured with the Dutch version of the short form of the Defining Issues Test). Between 1991 and 1997 a large sample of 846 Dutch adolescents and young adults (15–23 years in 1991) was measured three times with an interval period of 3 years. Moral reasoning scores increased with age both cross-sectionally and longitudinally, while delinquency scores dropped sharply, resulting in modest negative correlations between delinquency and moral reasoning. Structural equation modelling of the data delivered a satisfactory fit, suggesting statistical reciprocal effects between delinquency and moral reasoning for the total sample. A multigroup analysis for three different age cohorts revealed a consistent negative effect of previous delinquency on moral reasoning between the ages of 21 to 23 years. Between the ages of 24 to 26 years, however, delinquency scores were, in turn, negatively affected by previous moral reasoning. Although substantial gender differences in delinquency were reported, no such differences were obtained for either moral reasoning or its relationship with delinquency. The results are discussed in view of the need for a multidimensional process approach of the relation between moral judgment and delinquency.
