This study compared the Five-Factor and HEXACO personality correlates of two common self-control constructs - Tangney self-control and Grasmick self-control - and their relations with delinquency. In both a student and a community sample, conscientiousness (mainly the prudence facet) was the most consistent and strongest correlate of both constructs. HEXACO honesty-humility was an important correlate of Grasmick self-control but not of Tangney self-control. Additionally, honesty-humility (mainly the fairness facet) was the most consistent predictor of delinquency, whereas the two self-control scales differed in the extent to which they predicted delinquency across samples. © 2013.
