Abstract
This study explored agreement and potential relationships among perceived stress (self-reported using the Perceived Stress Scale), hair cortisol concentration (HCC), and mental disorders in a clinical sample of youth and their parents. Data were collected from a cross-sectional sample of 48 youth (38 females; mean age = 15.6 years) with a mental disorder and 72 parents (65 females; mean age = 45.49 years). Agreement was assessed using Bland-Altman plots and intraclass correlation coefficients. Multiple regression was used to model the association between covariates and HCC and perceived stress for youth and parents. Agreement between perceived stress and HCC was low for both youth and parents (ICC = 0.15 to 0.31). Among youth, lower income (β = 0.24) and parent psychopathology (β = 0.42) were associated with higher HCC. Female sex (β = 0.42) and higher parent psychopathology (β = 0.28) were associated with higher perceived stress, whereas chronic physical illness was associated with lower perceived stress (β = -0.24). Among parents, female sex (β = -0.21) was associated with lower HCC and family functioning (β = 0.46) was associated with higher perceived stress. In youth, higher HCC was associated with generalized anxiety (OR = 1.14) and higher perceived stress was associated with major depressive episode (OR = 1.33), generalized anxiety (OR = 1.10), and separation anxiety (OR = 1.14). Among parents, higher HCC was associated with depression (β = 0.27) and perceived stress was associated with depression (β = 0.53) and anxiety (β = 0.45). This exploratory study shows that agreement between psychological and physiological stress is low in a clinical sample of youth and their parents. Sociodemographic and psychosocial factors, and mental health, are differentially associated with psychological and physiological stress.

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
