Abstract
Although both reflect a self-centered, antisocial personality, psychopathy
and low self-control have seldom been examined together. This study created scales reflecting both common and unique elements of both constructs, investigated their factor structure, and explained variance in delinquency. Four alternative hypotheses were tested: that low self control and psychopathy constitute a single construct, that they constitute primary and secondary psychopathy or interpersonal and intrapersonal traits, or that they constitute Antisociality - the tendency to perform antisocial acts- and (low) Self-Direction-the tendency to act in one's long-term benefit. Models containing Antisociality and Self-Direction fit better than alternatives and accounted for substantial variance in offending.
