Abstract
This study investigated the changes in and the relationships among body mass index (BMI), global self-esteem, physical self-perceptions, social physique anxiety (SPA), physical activity, and dietary restraint in adolescent females over a 24-month period. Participants (N = 501) completed annual assessments in grade 9, 10, and 11. The results showed moderate covariance stability in all variables. There were several significant time effects (group mean change), with small increases in BMI, moderate decreases in physical activity, and very small changes over time in SPA and physical self-perceptions. Longitudinal analyses indicated that specific physical self-perceptions were important predictors of physical activity, dietary restraint and SPA; however, most of the variance was explained by previous year values. Evidence of bidirectional effects revealed that specific self-perceptions impact specific behaviors and SPA more so than the impact of behavior/emotion on self-perceptions. These results highlight the importance of understanding the physical self and its links to health-related behaviors and emotion in adolescents.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
