highly significantp < .001
The validity of the HIT has been supported in relation to numerous constructs, including the ability to distinguish delinquent from non-delinquent populations, and highly significant ( p < .001) positive correlations with measures of externalizing behavior ( r = .52), aggressive behavior ( r = .38), antisocial behavior ( r = .55), delinquent behavior ( r = .41), and low empathy ( r = .42) (Gini and Pozzoli 2013 ).
