The current study examined the relation between interpersonal callousness trajectories during adolescence (ages 14 to 18) and characteristics of antisocial personality and internalizing problems in young adulthood (age 26), using a community sample of 506 boys. The influence of several parent and peer factors on callousness trajectories during adolescence was also explored. Although the mean interpersonal callousness trajectory for the entire sample was relatively flat, there was substantial individual variability in both the initial status and rate of change of interpersonal callousness over time. Trajectories of interpersonal callousness were associated with higher levels of antisocial personality features in early adulthood but were unrelated to adult internalizing problems. Conduct problems and parent-child communication difficulties were the best predictors of elevated levels of interpersonal callousness throughout adolescence. However, none of the parenting and peer factors examined predicted substantive changes in interpersonal callousness over time.
Keywordscallous; psychopathy; antisocial personality; development; longitudinal; parenting; peers A defining feature of adult psychopathy is the presence of a callous interpersonal style, including being deceitful, manipulative, grandiose, superficially charming, lacking empathy and guilt, and not accepting responsibility for transgressions. Features of interpersonal callousness (IC) have been identified in children and adolescents, and emerging research suggests that these features delineate a particularly malignant form of antisocial behavior (Frick, Cornell, Barry, Bodin, & Dane, 2003;Loeber, Burke, & Lahey 2002;Loeber et al., 2005;Pardini, 2006;Pardini, Obradović, & Loeber, 2006). Although some have speculated that features of IC in youth are stable across time and represent the foundation for adult antisocial or psychopathic personality disorders (Lynam et al., 2005), relatively few longitudinal studies have examined the within-individual stability of IC during adolescence or examined the association between IC features in adolescence and later adult antisocial personality (AP; for exceptions, see Burke, Loeber, & Lahey, 2007;Loeber et al., 2002). Furthermore, although many researchers have emphasized the potential genetic and neurobiological factors underlying the development of IC, there is little research examining the influence of important socializing agents (e.g., parents, peers) on changes in IC during adolescence. However, a growing body of evidence suggests that parenting practices and peer characteristics may be important for understanding the development of IC in youth Correspondence regarding this article may be sent to Dustin Pardini, Ph.D., University of Pittsburgh Medical Center, 120 Lytton Ave., University Center #250, Pittsburgh, PA 15213; dap38@pitt.edu.
