Fiche synthèse

1. Objectifs


Intentions :
«In this study, [the authors] tested the putative role of peer victimization and harsh parenting in the association between childhood irritability and suicidal ideation and attempt in adolescence.» (p. 1403)

2. Méthode


Échantillon/Matériau :
«Participants were from the QLSCD [Quebec Longitudinal Study of Child Development], conducted by the Institute de la Statistique du Québec. This cohort included 2120 children born in 1997/1998, selected with a stratified random procedure, from a mother residing in the Canadian province of Québec […].» (p. 1403) «Analyses were based on 1483 children (representing 70% of the original sample) for which information on suicidal ideation and suicide attempt at ages 13, 15, 17, and 20 years (at least one data point) and irritability at ages 6, 7, 8, 10, and 12 years (at least one data point) were available.» (p. 1403)

3. Résumé


The authors «found that peer victimization mediated a significant proportion of the association between irritability and suicide attempt, but not suicidal ideation. Specifically, [they] found that children following rising and persistent trajectories of irritability in childhood were more likely to attempt suicide in adolescence, and that 33–35% of this risk was explained by exposure to peer victimization. [They] did not find evidence for a mediating role of harsh parenting in the association between rising and persistent irritability trajectories and suicide attempt.» (p. 1407) The authors «found that children with persistent irritability experienced harsher parenting practices than children with low levels of irritability. However, [they] did not find a mediation effect of harsh parenting in the association between irritability and suicide attempt, suggesting that this is not a mechanism accounting for the heightened suicidal risk of irritable children.» (p. 1407-1408)
