The purpose of this study was to investigate the relationship between self-reported offending and personality. A total of 1603 students in further education in Iceland completed the Mak Self-Reported Delinquency Scale as well as a number of psychological tests, namely the Eysenck Personality Questionnaire (EPQ and IVE), the Gough Socialisation Scale, the Rosenberg Self-Esteem Scale, and the Gudjonsson Compliance Scale. Multiple regression analyses showed that five out of the 10 individual personality scales contributed 27 and 30 per cent to self-reported offending for males and females, respectively. Overall, the Gough Socialisation Scale and EPQ psychoticism contributed most to the variance in self-reported offending, but impulsivity, extraversion and a low lie score also added significantly to the variance after interactions among the personality measures had been taken into account. Some gender differences emerged with impulsivity being a better predictor of offending among the males than females. Overall, the findings give strong support for the hypothesis that personality, particularly those relating to antisocial personality traits, is significantly related to self-reported offending in both males and females.
