Physical activity plays an important role in individuals' physical and psychological health. However, there is scarce evidence on how physical activity is associated with socioemotional aspects in gifted students. This is of special importance since previous research showed that gifted students scored significantly lower on physical self-concept…

Introduction: According to Self-Determination Theory, it is known that motivation is an essential factor for the adherence and enjoyment of exercise, generating long-lasting habits. The importance of generating such habits from an early age is a determining factor in the future health of people. The child and youth population invests a great…

Research has established that qualities of student-teacher relationships impact children's self-concept, however, the role of teacher and child gender in these relations is unclear. This study used data from 4169 children aged 10-11 years and 3343 teachers from Wave 4 of the Longitudinal Study of Australian Children to examine the relationship…

The goal of this study was to examine links between observed social participation in the schoolyard and indices of socio-emotional functioning in early adolescence. Participants were children (N = 290) aged 9 to 12 years. Social participation (e.g., solitary play, dyadic interaction, group interaction) was assessed in the schoolyard during recess…

For decades, research has indicated that preadolescents' self-concept is comprised of subject-specific academic factors, a general academic factor, and several nonacademic factors. More recently, there have been some indications that academic self-concept might further be differentiated into competence and affect factors, at least for some…

This study aims to develop a short German version of the Self Description Questionnaire (SDQ I-GS) in order to present a robust economical instrument for measuring German preadolescents' multidimensional self-concept. A full German version of the SDQ I (SDQ I-G) that maintained the original structure and thus length of the English original SDQ I…

The current study investigated the gender differences of gifted adolescents' math/verbal self-concept and math/verbal ability by examining the Internal/External Frame of Reference Model (I/E model; Marsh, 1986). The sample consisted of 181 gifted adolescents, ranging in age from 12 to 16 years old. Gifted adolescents' math/verbal ability was…

Test-retest data (six-month interval) collected on preadolescent student self-concepts, teachers' ratings of student self-concepts, and academic ability provided strong support for the construct validity of self-concept. The multiple dimensions of self-concept showed a logical and consistent pattern of relationships with a variety of criteria.…

Two studies compared multidimensional self-concept measures in preadolescents. Findings indicated that the Self-Description Questionnaire and Self-Perception Profile for Children were highly correlated and comparable in reliability, stability, subscale interrelations, and associations with others' evaluations. Correspondence among various…

The purposes of the present investigation are to compare the structure and level of multidimensional self-concepts for boys and girls from England and Australia, and to demonstrate the use of confirmatory factor analysis (CFA) in making such comparisons. Subjects were random samples of 303 English preadolescents and 303 Australians that were…

Agreement between multidimensional self-concept ratings by preadolescents and inferred self-concept ratings by teachers and parents was studied for 188 Australian children in grades 3 through 6. Children and significant others completed the Self-Description Questionnaire I. The degree of self-other agreement is discussed. (SLD)

Confirmatory factor analysis of responses by 211 preadolescents (M age = 10.25 years,SD = 1.48) with mild intellectual disabilities (MIDs) to the individually administered Self Description Questionnaire I-Individual Administration (SDQI-IA) counters widely cited claims that these children cannot differentiate multiple self-concept factors. Results…

This analysis of 12,266 responses to the 3 Self-Description Questionnaires (which measure dimensions of self-concept in preadolescence) examined age and sex effects during preadolescence and early adulthood and alternative operationalizations of the proposition that self-concept becomes more differentiated with age. Well-defined factor structures…

The construct validity of 290 preadolescent children's responses to 3 instruments claiming to measure dimensions of self-concept was studied. Instruments administered to the fifth graders include the Self-Description Questionnaire; the Perceived Competence Scale; and the Piers-Harris Children's Self-Concept Scales. (SLD)
