1. Objectifs

Intentions :
«The objective of the present study [is] to examine whether the interaction between parenting practices and inhibitory control predicts the common and/or unique variance of hyperactivity-impulsivity and inattention, and whether this interaction supports the diathesis-stress, vantage sensitivity, or differential susceptibility model. More specifically, [the authors] tested whether inhibitory control, measured at 6 years of age, moderates the link between parenting (positive parenting observed at 4 years of age and negative parenting reported at 5 years of age) and hyperactivity-impulsivity and inattention measured at 7 years of age.» (p. 911)

2. Méthode

Échantillon/Matériau :
«Participants come from a longitudinal study on the social, psychological, and cognitive development of children in Québec, Canada[.]» (p. 911) «In total, 195 mothers participated in these observations with their child (56.4% girls) and form the sample of the present study.» (p. 912)

3. Résumé

«The present study found that positive parenting and inhibitory control interact in the prediction of the common variance of hyperactivity-impulsivity and inattention. Children with low inhibitory control exhibited higher levels of hyperactivity-impulsivity/inattention regardless of parenting practices. Children with high inhibitory control had similar levels of hyperactivity-impulsivity/inattention as those with low inhibitory control when exposed to lower levels of positive parenting, but had lower levels of hyperactivity-impulsivity/inattention when exposed to higher levels of positive parenting. This interaction supported the vantage sensitivity model, which posits that some individuals show an increased sensitivity to positive experiences exclusively. The findings of this study suggest that a targeted prevention approach could be particularly efficient to reduce the risk of developing ADHD [attention deficit hyperactivity disorder] symptoms. Inhibitory control would be the intervention target when it is low, but when it is high, parenting would be the intervention target.» (p. 919)
