Fiche synthèse

1. Objectifs


Intentions :
« The objectives of the study were to model the developmental trajectories of physical aggression (PA) from toddlerhood to pre-adolescence and to identify risk factors that distinguish typical (normative) from atypical developmental patterns. » (p. 68)

Questions/Hypothèses :
« (1) [W]hat are the typical (normative) developmental trajectories of PA between 2 and 11 years of age?
(2) Is there a group of children who follow atypically elevated trajectories of PA throughout that age period?
(3) Is there a group of children who are not physically aggressive during toddlerhood but become physically aggressive as they enter school?
(4) Do sex differences become gradually larger between 2 and 11 years of age? and
(5) What risk factors distinguish children who follow an atypically high PA trajectories from those who do not? » (p. 71)

2. Méthode


Échantillon/Matériau :
« Ten cohorts of approximately 1,000 children (n = 10,658) drawn form a nationally representative (Canadian) sample were followed over 6 years. » (p. 68)

3. Résumé


« Using a group-based trajectory approach, we identified three groups of children with distinct developmental trajectories between 2 and 11 years of age. One third of the children (31.1%) followed a low desisting trajectory, reflected in infrequent use of PA in toddlerhood and virtually no PA by pre-adolescence. The majority of children (52.2%) followed a moderate desisting trajectory, reflected in occasional use of PA in toddlerhood and infrequent use by pre-adolescence. One sixth of the children (16.6%) followed a high stable trajectory of PA. Multivariate logistic regression indicated that children in the high PA trajectory group were more likely to be boys [...], from low income families [...], from families where the mother had not completed high school [...] and who reported using hostile/ineffective parenting strategies [...]. In sum, the results indicate that the typical developmental pattern of PA was one of occasional and declining use over time. However, about one sixth of children, mostly boys from disadvantaged families, exhibited an atypical developmental pattern reflected in more frequent and stable use of PA. The results suggest that most children learned relatively well to inhibit PA by the end of childhood and that a minority failed to do so. Family risks traditionally found to be associated with antisocial behaviors during adolescence appear to interfere with the socialization of PA during early and middle childhood. » (p. 68)
