Extraversion, Neuroticism, Psychoticism and Self-reported Delinquency: Evidence from Eight Separate Samples

Eight separate samples of high school and university students (Total N = 410) in Britain and Canada were used to test predictions from Eysenck’s theory that delinquents should be high scorers on scales of extraversion, neuroticism, and psychoticism. Self-report paperand pencil-questionnaire measures of both personality and delinquency were administered under conditions that ensured anonymity. The evidence showed clear support for a relationship between high delinquency scores and high scores on both extraversion and psychoticism. These relationships held up across diverse samples and different ways of analyzing the data. No support was found for a relationship between delinquency scores and the dimension of neuroticism.
