Given the importance of writing for academic achievement, this study aimed to understand how early oral language contributes to later writing skills. The first objective was to determine if preschool language skills were associated with high school writing, and if so, whether they contributed directly or indirectly through school age language. The…

Morneau-Vaillancourt, Geneviève; Matte-Gagné, Célia; Cheesman, Rosa; Brendgen, Mara; Vitaro, Frank; Tremblay, Richard; Dionne, Ginette; Boivin, Michel – Developmental Psychology, 2021
The present study examined, within a longitudinal family-informed design and across middle childhood, the predictive associations between preference for solitude and social wariness, two forms of social withdrawal, and peer difficulties. Specifically, preference for solitude, rather than social wariness, was expected to predict peer victimization…

There is little research to date on the academic implications of teaching twins in the same or different classroom. Consequently, it is not clear whether twin classroom separation is associated with positive or negative educational outcomes. As a result, parents and teachers have insufficient evidence to make a well-informed decision when twins…

Background: The number line task assesses the ability to estimate numerical magnitudes. People vary greatly in this ability, and this variability has been previously associated with mathematical skills. However, the sources of individual differences in number line estimation and its association with mathematics are not fully understood. Aims: This…

Guimond, Fanny-Alexandra; Laursen, Brett; Vitaro, Frank; Brendgen, Mara; Dionne, Ginette; Boivin, Michel – International Journal of Behavioral Development, 2016
This study used a genetically controlled design to examine the direction and the magnitude of effects in the over-time associations between perceived relationship quality with mothers and adolescent maladjustment (i.e., depressive symptoms and delinquency). A total of 163 monozygotic (MZ) twins pairs (85 female pairs, 78 male pairs) completed…

Brendgen, Mara; Vitaro, Frank; Boivin, Michel; Girard, Alain; Bukowski, William M.; Dionne, Ginette; Tremblay, Richard E.; Perusse, Daniel – Journal of Child Psychology and Psychiatry, 2009
Background: Genetic risk for depressive behavior may increase the likelihood of exposure to environmental stressors (gene-environment correlation, rGE). By the same token, exposure to environmental stressors may moderate the effect of genes on depressive behavior (gene-environment interaction, GxE). Relating these processes to a peer-related…

Vitaro, Frank; Barker, Edward D.; Brendgen, Mara; Tremblay, Richard E. – Journal of Child Psychology and Psychiatry, 2012
Objective: This study aimed to identify the pathways through which a preventive intervention targeting young low-SES disruptive boys could result in lower crime involvement during adulthood. Method: The preventive intervention was implemented when the children were between 7 and 9 years and included three components (i.e. social skills, parental…

Veronneau, Marie-Helene; Vitaro, Frank; Brendgen, Mara; Dishion, Thomas J.; Tremblay, Richard E. – Developmental Psychology, 2010
This study tested a transactional model of reciprocal influences regarding students' peer experiences (peer acceptance, peer rejection, and friends' academic achievement) and students' academic achievement from middle childhood to early adolescence. This longitudinal model was tested on 452 students (198 girls), mostly Caucasian and French…

Rivizzigno, Alessandra S.; Brendgen, Mara; Feng, Bei; Vitaro, Frank; Dionne, Ginette; Tremblay, Richard E.; Boivin, Michel – Merrill-Palmer Quarterly: Journal of Developmental Psychology, 2014
Enriched environments may moderate the effect of genetic factors on prosocial leadership (gene-environment interaction, G × E). However, positive environmental experiences may also themselves be influenced by a genetic disposition for prosocial leadership (gene-environment correlation, rGE). Relating these processes to friendships, the present…

Witvliet, Miranda; van Lier, Pol A. C.; Brendgen, Mara; Koot, Hans M.; Vitaro, Frank – Journal of Clinical Child and Adolescent Psychology, 2010
This study examined the longitudinal link between clique membership status and the development of psychopathology in 451 children followed annually from age 9 to 12 years. Classroom clique membership status was identified through social network analysis, and internalizing and externalizing problems were assessed using peer nominations. Controlling…
