Gorin, Hillary. 2016. «The Emergence of Psychopathic Traits: Examining a Temperament X Environment Interaction». Mémoire de maîtrise, Chicago (Illinois), Université Rosalind Franklin de medicine et de science, Département de psychologie.
Intentions : «[T]he present study was designed to examine how temperament in toddlerhood is related to the development of psychopathic traits in later childhood, how negative life events/hostile-reactive parenting is related to the development of psychopathic traits in later childhood, and whether Temperament X Environment (negative life events/hostile-reactive parenting) interactions predict growth or change in psychopathic traits over time.» (p. 4)
Questions/Hypothèses : «I hypothesized that higher scores on negative life events and hostile-reactive parenting would be related to more psychopathic traits and growth in psychopathic traits over time.» (p. 38)
Échantillon/Matériau : «The data for this study were obtained in the Quebec Longitudinal Study of Child Development (QLSCD) (or the ELDEQ database) [...]. [The QLSCD] has gathered data on youth from 5 months (in 1998) thru 17 years of age. Data have been collected annually since 1998 in a cohort of 2,223 Québec infants.» (p. 40) «Although data were available in the ELDEQ dataset for 2,233 children, data from only 1250 of these children were included in measurement model analyses and data from 1148 of these children were included in the primary analyses of this study […]» (p. 41)

The author concludes that, «[o]verall, it appears that extraversion and hostile reactive parenting in early childhood are uniquely predictive of the development of psychopathic traits in middle childhood» (p. 5) and adds that «[i]n regard to environmental predictors, the level of hostile reactive parenting at age 29 months positively predicted the levels of lifestyle/antisocial and interpersonal features at 6 years of age.» (p. 81) Results show that «[h]ostile reactive parenting did not predict change in any component of psychopathic traits [and also] did not predict affective traits […].» (p. 82) «It is possible the instant finding suggests that hostile reactive parenting may not be as prominent a risk factor in the development of affective traits as it is in the development of interpersonal and lifestyle/antisocial traits.» (p. 83)
