Family history of cancer as a cue to action for physical activity behaviour and beliefs
Bibliographic record
Abstract
Objective: Examine if family history of cancer serves as a cue to action prompting adults to assess their personal risk of cancer, consider the consequences, and engage in physical activity (PA) if they believe it will reduce their risk.Design: Cross-sectional survey of adults with and without a close relative with cancer.Main Outcome Measures: Health Belief Model (HBM) constructs of perceived cancer vulnerability, perceived cancer severity, response effectiveness of PA, self-efficacy for PA, and barriers to PA, and moderate-to-vigorous intensity PA (MVPA).Results: Perceived barriers and self-efficacy correlated with MVPA in both groups (p < .05), and perceived vulnerability and response effectiveness correlated with MVPA in participants with a close relative with cancer (p < .05). In multiple regression analyses, HBM constructs accounted for 18.5% and 8.3% of the variability in MVPA among participants with and without a close relative with cancer, respectively. Participants with a close relative with cancer had greater perceived vulnerability to cancer compared to participants without a close relative with cancer (p < .001).Conclusion: Adults with and without a close relative with cancer may be differentially influenced by HBM constructs, and as a result may respond differently to PA interventions and public health messaging.

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.
