Intelligence, Executive Functions, and Decision Making as Predictors of Antisocial Behavior in an Adolescent Sample of Justice-Involved Youth and a Community Comparison Group

摘要

A clinical sample of justice-involved male adolescents and a community comparison group were compared on a battery of cognitive ability tasks (intelligence and executive functions), decision making measures, and other individual difference measures, including ratings of self-control, recognition of morally debatable behaviors, and antisocial beliefs. The clinical sample displayed lower performance on cognitive abilities and decision making than the community comparison group. In particular, the clinical group displayed less otherside thinking and more hostile attribution biases in unintentional situations compared with the community comparison group. Cognitive abilities and the decision making performance predicted group membership. Then, group membership, ratings of self-control, attitudes about morally debatable behaviors, and antisocial beliefs predicted ratings of antisocial behavior in the full sample. These findings suggest that measures of cognitive ability and decision making make separate contributions to explaining antisocial behaviors. In addition, the predictors of group membership and antisocial behavior did not overlap, suggesting that antisocial behavior engagement in clinical samples may be separable from the continuum of antisocial behavior across the full sample. Cognitive science models of decision making can provide a framework for understanding antisocial behavior in clinical and community samples of adolescents. Copyright (c) 2015 John Wiley & Sons, Ltd.
