Purpose: The objective of this study was to compare children with persistent versus transient preschool language delay on language, academic, and psychosocial outcomes in elementary school. Method: Children with persistent language delay (n = 30), transient language delay (n = 29), and no language delay (controls; n = 163) were identified from a…

This study examined the associations between intrinsic motivation and achievement in mathematics in a sample of 1,478 Canadian school-age children followed from Grades 1 to 4 (ages 7-10). Children self-reported their intrinsic motivation toward mathematics, whereas achievement was measured through direct assessment of mathematics abilities.…

This study examined the contribution of nonparental child-care services received during the preschool years to the development of social behavior between kindergarten and the end of elementary school with a birth cohort from Québec, Canada (N = 1,544). Mothers reported on the use of child-care services, while elementary school teachers rated…

This study explored whether early elementary school aged children's externalizing problems impede academic functioning and foster negative social experiences such as peer victimization, thereby making these children vulnerable for developing internalizing problems and possibly increasing their externalizing problems. It also explored whether early…

This study assessed the genetic and environmental contributions to peer difficulties in the early school years. Twins' peer difficulties were assessed longitudinally in kindergarten (796 twins, "M"[subscript age] = 6.1 years), Grade 1 (948 twins, "M"[subscript age] = 7.1 years), and Grade 4 (868 twins, "M"[subscript…

Background: There are two approaches to the differential examination of school motivation. The first is to examine motivation towards specific school subjects (between school subject differentiation). The second is to examine school motivation as a multidimensional concept that varies in terms of not only intensity but also quality (within school…

Several authors consider high and frequent conflicts between friends during childhood as a serious risk for subsequent conduct problems such as generalized physical aggression toward others (e.g., Kupersmidt, Burchinal, & Patterson, 1995; Sebanc, 2003). Although it seems logical to assume that friendship conflict could have some negative…

This study evaluated the relations of peer status, self-perceptions, and other-perceptions of social competence among 9- and 11-year-old children. Self-esteem, self-perception in different domains, and teachers' assessments were examined along with peer status. (PCB)

This study examined the changes in children's social network and specific self-perceptions during the transition from elementary school to junior high school (JHS). The participants were 200 preadolescent children (104 girls, 96 boys). Children's self-perceptions (global self-worth, perceived academic competence, and perceived social acceptance)…

Evaluated a social process model describing how aggression and withdrawal lead to negative social self-perception. Subjects were 793 French Canadian elementary school children. Found that withdrawal behavior uniquely predicted social self-perceptions. Both negative peer status and peer victimization successively mediated the impact of social…

Evaluated the factor structure, reliability, and validity of a French version of the Self-Perception Profile for Children. The profile was administered to elementary school students in Quebec, and results were correlated with teacher and peer assessments. Results supported a five-factor solution and indicated that each factor was reliably…
