This study investigates heterogeneity in adolescents' trajectories of global self-esteem (GSE) and the relations between these trajectories and facets of the interpersonal, organizational, and instructional components of students' school life. Methodologically, this study illustrates the use of growth mixture analyses, and how to obtain…

This study assessed the unique effects of racial identity and self-esteem on 259 African American adolescents' depressive and anxiety symptoms as they transitioned from the 7th to 8th grades (ages 12-14). Racial identity and self-esteem were strongly correlated with each other for males but not for females. For both males and females, an increase…

Investigated hypothesis that individuals evaluate self-worth differently across relational contexts while holding perceptions of global self-worth. Found that adolescents' self-worth perceptions varied across contexts. Support in a given context was more highly correlated with relational self-worth in the corresponding context than in other…

Developmental change in self-esteem was assessed from early adolescence through early adulthood. Found that males tended to increase and females to decrease in self-esteem over time and that there was rank order consistency in self-esteem over time. Within each gender, individuals' differences in developmental trajectories were related to…

The influence of the sleep patterns of 2,259 students, aged 11 to 14 years, on trajectories of depressive symptoms, self-esteem, and grades was longitudinally examined using latent growth cross-domain models. Consistent with previous research, sleep decreased over time. Students who obtained less sleep in sixth grade exhibited lower initial…

This behavioral genetic study examined perceived competence and self-worth in same-sex twins, siblings, and stepsiblings 10 to 18 years old, and again 3 years later. Findings at second assessment showed six of seven subscales heritable. Genetic contributions to stability were found for perceived scholastic competence, athletic competence, physical…

Developmental trajectories of personal and collective self-concept were examined among American Indian adolescents. Personal self-concept (self-esteem) and collective self-concept (American Indian identity, Euro-American identity, community-mindedness) were assessed 6 times over 3 years in 4 cohorts of adolescents from 3 American Indian cultural…

Seventy-seven adolescents in 2-parent families and their parents were observed in a revealed-differences interaction task when the adolescents were age 14, and the adolescents' ego development and self-esteem were assessed at both age 14 and 16. Adolescents' displays of autonomy and relatedness were strongly related to concurrent measures of ego…

Examined whether differentiating processes existed for 7 composite indices of positive and negative adolescent adjustment in 720 sibling pairs. Found that siblings born 1 year apart at Time 1 were more similar to each other than were siblings born 2 years apart, suggesting that shared environmental influences counteract sibling differentiation…
