Global self-esteem, perceived athletic competence, and physical activity in children: A longitudinal cohort study

Objectives: The Exercise and Self-Esteem Model is used as a theoretical framework to describe associations between global self-esteem and physical activity, mediated by perceived athletic competence. We know little about how these associations develop over time in elementary school children. We examined the change in, and associations between, global self-esteem, perceived athletic competence, and moderate-to-vigorous physical activity (MVPA) in children from kindergarten to grade 4. We also investigated if this change and these associations were different for boys and girls. Design: A prospective longitudinal cohort-sequential design that consisted of two cohorts of children. Method: Children in cohort I were followed from kindergarten to grade 2, and children in cohort II were followed from grade 2 to grade 4. Global self-esteem and perceived athletic competence were measured with the Self-Perception Profile for Children (SPPC) (n=292; 148 boys), while MVPA was measured with proxy-reports for physical activity filled in by parents (n=184; 88 boys). Results: Global self-esteem, perceived athletic competence, and MVPA remained stable. Global self-esteem was the same in boys and girls, while boys reported higher levels of perceived athletic competence and were more physically active than girls. The change in global self-esteem was significantly associated with perceived athletic competence and MVPA in girls, but not in boys. Conclusion: There are few developmental changes in global self-esteem, perceived athletic competence, and MVPA from kindergarten to grade 4. The change in global self-esteem was associated with perceived athletic competence and MVPA in girls, but not in boys
