1. Objectifs

Intentions :
«L’objectif de la présente thèse [par articlse] était [...] d’identifier les patrons et les différences individuelles dans le développement des comportements prosociaux au cours de l’enfance et de l’adolescence, ainsi que d’examiner les associations longitudinales entre les comportements prosociaux et les problèmes extériorisés et intériorisés.» (p. v) The goal of the second article is to «describe and predict the joint development of prosocial behaviours with physical aggression, anxiety, and depression from 2 to 11 years of age.» (p. 55)

2. Méthode

Échantillon/Matériau :
«Participants were 10 700 children from the National Longitudinal Survey of Children and Youth. Developmental trajectories, spanning ages 2 to 11, were modeled using an accelerated group-based design.» (p. 55)

Instruments :
Questionnaires

Type de traitement des données :
Analyse statistique

3. Résumé

«Children following a high prosocial trajectory were more likely to follow a low physical aggression, and low depression trajectory. However, they were also more likely to follow a low or high anxiety trajectory. Boys were significantly more likely to follow a low prosocial behaviour trajectory, particularly in the context of high physical aggression or decreasing anxiety trajectory membership. Positive parenting was most strongly associated with prosocial behaviours, while hostile parenting was most predictive of physical aggression, anxiety, and depression development. Low family income and maternal depression increased the likelihood of jointly exhibiting high prosocial behaviours and high problem behaviours. [...] Individual differences exist in the association of prosocial behaviours with mental health. While high prosocial behaviour levels tend to develop in the context of low problem behaviours, high prosocial and problem behaviours can co-occur in subgroups of individuals. Child, mother, and family characteristics are predictive of individual differences in joint prosocial and problem behaviour development. Mechanisms underlying these associations warrant future investigations.» (p. 55)
