Effects of Targeted Print Materials on Physical Activity and Quality of Life in Young Adult Cancer Survivors During and After Treatment: An Exploratory Randomized Controlled Trial
Bibliographic record
Abstract
Purpose: To explore the effects of targeted physical activity (PA) print material on PA and quality of life (QOL) in young adult cancer survivors (YACS) aged 18–39 either on or off treatment. Methods: YACS ( N =212) recruited from a cancer registry were randomly assigned to a Targeted Physical Activity Guidebook (TPAG) or the Canadian Physical Activity Guidelines (CPAG). An online or mailed survey assessed the primary outcome of self-reported PA minutes and secondary QOL outcomes. Assessments were conducted at baseline, 1 month, and 3 months for PA and at baseline and 3 months for QOL. Results: At 3 months, analyses of covariance showed no differences between the groups for the primary outcome of PA minutes/week (adjusted mean group difference=+8 minutes; 95% confidence interval [CI]: −60 to +77; p =0.81). The TPAG was superior to the CPAG for the mental component of QOL (adjusted mean group difference=+3.1; 95% CI: +0.1 to +7.3; p =0.043). In an exploratory analysis of YACS reporting ≤300 PA minutes/week at baseline ( N =108), the TPAG group was superior to the CPAG group at 3 months for PA minutes/week (adjusted mean group difference=+90; 95% CI: +10 to +170; p =0.028). Conclusion: Targeted PA print material did not increase PA compared to generic PA print material in a highly active sample of YACS. In YACS reporting ≤300 PA minutes/week at baseline—the group of interest from a PA behavior change perspective—the targeted PA print material was effective in increasing PA.

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.
