title: Extraversion, neuroticism, immoral judgment and criminal behaviour.
abstract: The present study examines delinquent behaviour by integrating two approaches until now employed separately: Eysnck's theory linking delinquency to extraversion and neuroticism, and Kohlberg's theory of moral development and its connection to moral behaviour. The study analyzes the relations between extraversion, neuroticism and moral judgment, as well as their independent and/or interactive effect upon the development of anti-social behaviour. The relationships are tested by retrospective measurements of personality traits and moral judgment in three groups: delinquency (N = 203), control (N = 82) and comparative (N = 407) groups. Findings show that criminals are higher than control subjects in neuroticism and immoral judgment but not in extraversion. Similar relationships were found between criminals and the comparative group, with one exception: here extraversion was found to be positively related to delinquency, both independently and interactively with neuroticism. The implications of these results for differential development of anti-social behaviour are discussed.
