Effects of physical activity on depression in adult females
Bibliographic record
Abstract
A number of reviews/meta-analyses have shown the positive effects of physical activity on depression (Schuch et al., 2016). Females report twice the rates of depression than males (Pearson, Janz, & Ali, 2013). The purpose of this presentation is to report the results of 2 experimental studies examining the effects of PA on depression in female adults. The first was an RCT comparing a physical activity intervention, a behavioural activation intervention and a control condition. The second was a multiple single subject study using a physical activity counsellor to help depressed female undergraduate students increase their physical activity. For study 1, a mixed ANOVA was conducted to assess the impact of the 3 conditions on depressive symptoms. The physical activity intervention showed a significant reduction in depressive symptoms, F(2, 54.74) = 3.49, p

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
