1. Objectifs

Intentions :
«Using data from a large population-based birth cohort of children from Canada, [this study] first aimed to examine the association between MLP [moderate to late preterm] birth and the trajectory of overprotective parenting practices during preschool years. [It] also aimed to determine if parental overprotection might explain the documented relation between MLP birth status and child hyperactivity-impulsivity and inattention symptoms, and whether this parental behavior mediates or interacts with MLP in the prediction of these symptoms.» (p. 1557)

Questions/Hypothèses :
«[The authors] expected MLP birth status to be associated with a higher trajectory of parental overprotection between 5 and 29-months (i.e. more overprotective practices that persist across time). Furthermore, in line with previous literature, [they] also expected MLP birth status to be associated with higher trajectories of hyperactivity-impulsivity and inattention between 4 and 8 years of age (i.e. higher levels that persist across time). In addition, [they] predicted overprotective parenting would be a mediator in the relation between MLP birth status and the trajectory of hyperactivity-impulsivity and inattention between 4 and 8 years of age. Finally, [they] also expected overprotective parenting to interact with MLP birth status in the prediction of these trajectories.» (p. 1557)

2. Méthode

Échantillon/Matériau :
«This study used data from the Quebec Longitudinal Study of Child Development (QLSCD), a Canadian representative population-based study of children’s growth and development. […] The sample includes 2128 children born between 32 and 41 gestational weeks for which [there is] data regarding parental overprotection and hyperactivity-impulsivity or inattention during childhood. This longitudinal study used repeated measures of overprotective parenting when children were 5 [...], 17 [...], and 29 months of age [...].» (p. 1557)

3. Résumé

«The results of this study revealed that MLP birth was associated with a slower decrease in parental overprotection across the preschool period and that both MLP birth and parental overprotection were independent predictors of the trajectory of children’s hyperactivity-impulsivity. Moreover, MLP birth, but not parental overprotection, predicted inattention during childhood. […] The overall trajectory of parental overprotection from 5 to 29 months revealed a small decrease across time.» (p. 1562) «However, a relation emerged between MLP birth and overprotection across time, such that parents of MLP children were found to be more overprotective at 29 months than those of FT [full-term children.» (p. 1563) Authors also found that «parental overprotection was related to higher levels of hyperactivity-impulsivity across childhood. […] Various factors may help explain the relation between parental overprotection and hyperactivity-impulsivity in children.» (p. 1563) Finally, they observed that «children’s MLP birth status was found to be associated with higher levels of hyperactivity-impulsivity and inattention between 4 and 8 years old.» (p. 1563-1564)
