PARDINI, Auteur Article en page(s) : p.55-63 Langues : Anglais (eng) Mots-clés : Interpersonal callousness  conduct problems  psychopathy  trajectories Index. décimale : PER Périodiques Résumé : Background Studies have demonstrated a robust association between interpersonal callousness (IC) and the development of severe and chronic conduct problems (CP) in youth. Although children exhibiting IC are also believed to be at particularly high risk for developing psychopathic personality features in adulthood, there is little longitudinal evidence supporting this assumption, particularly after controlling for co-occuring CP severity. Methods This study used data collected on a longitudinal cohort of boys (n = 508), with an oversampling of youth exhibiting elevated conduct problems. Analyses examined the unique and interactive association between latent growth curve trajectories of IC and CP assessed bi-annually from late childhood to early adolescence (~ages 10–13) and features of psychopathy in early adulthood (age ~ 24) assessed using the Psychopathy Checklist – Short Version (PCL:SV; Hart, Cox, & Hare, 1995). Results Growth curve analysis indicated that initial levels of IC and CP in childhood (~age 10 intercept) both uniquely predicted the development of the interpersonal/affective features of adult psychopathy, and boys with a combination of high initial levels of IC and CP were at particularly high risk for developing the impulsive/antisocial features of the disorder. Boys who exhibited systematic increases in CP from late childhood to early adolescence also demonstrated higher adult psychopathy scores, but changes in IC across this developmental period did not significantly add to the prediction of adult psychopathy. Conclusions Findings highlight the importance of developing targeted interventions for boys exhibiting severe IC and CP in childhood, as they appear to be at high risk for developing adult psychopathic features.

The stability of psychopathy across adolescence / Donald R. LYNAM in Development and Psychopathology, 21-4 (November 2009)  

Public ISBD [article]  inDevelopment and Psychopathology > 21-4 (November 2009) . - p.1133-1153 Titre : The stability of psychopathy across adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Donald R. LYNAM, Auteur ; Terrie E. MOFFITT, Auteur ; Rolf LOEBER, Auteur ; Magda STOUTHAMER-LOEBER, Auteur ; Adrian RAINE, Auteur ; Richard CHARNIGO, Auteur Année de publication : 2009 Article en page(s) : p.1133-1153 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The current diagnostic system suggests that personality disorder categories be applied to children and adolescents in rare circumstances because of expected changes in personality pathology across development. The present study examined the stability in personality pathology, specifically psychopathy, across childhood and adolescence. Using a short form of the CPS and mixed models incorporating fixed and random effects, we examined the reliability, individual stability, mean-level stability, and predictive utility of juvenile psychopathy as a function of age (i.e., from 7 to 17 years old) in over 1,500 boys from the three cohorts of the Pittsburgh Youth Study. If adolescent development contributes to instability in personality pathology, large age-related fluctuations in reliability, stability, and predictive utility should be observed, particularly in the latter part of adolescence when normative changes are hypothesized to influence levels of psychopathy. Such fluctuations were not observed. In general, juvenile psychopathy could be reliably assessed beginning in childhood, was fairly stable across short and long intervals, showed little mean-level fluctuation, and predicted delinquency across adolescence. These results suggest that concerns about large changes in personality pathology across childhood and adolescence may be overstated. Implications and future directions are discussed.
