Examining the Physical Self in Adolescent Girls Over Time: Further Evidence against the Hierarchical Model
Bibliographic record
Abstract
This research examined the direction of causal flow between global and specific dimensions of self-concept. Although the multidimensionality of self-concept has been strongly supported in the literature, the hierarchical nature of self-concept has not been established. With the use of structural equation modeling, the hierarchical nature of self-concept was tested using the Physical Self-Perception Profile (PSPP) model both with and without global self-esteem included. Adolescent girls (N = 618) completed the PSPP and Harter’s global self-esteem scale during class time in Grade 9 and a year later in Grade 10. When horizontal effects were included in the self-concept models across age, there was little support for either top-down or bottom-up effects. This contrasted with the results found when the analysis was conducted within each time period separately. This research provides further evidence against the hierarchical model of self-concept and highlights the importance of examining the hierarchical nature of self-concept over time.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
