Abstract
In Brief OBJECTIVE Home-based cardiac rehabilitation (CR) programs have been shown to be effective in increasing exercise capacity, which is a significant predictor of longevity for patients with heart disease. However, adherence to these programs has been problematic. Therefore, it is important to identify key theoretical correlates of exercise for these patients that can be used to inform the development of behavioral interventions to help tackle the adherence problem. The purpose of this study was to determine whether protection motivation theory (PMT) explained significant variation in exercise intentions and behavior in patients receiving home-based CR. METHODS Patients (N = 76) completed a questionnaire that included PMT constructs at the beginning and midpoint (ie, 3 months) of the program and an exercise scale at 3 and 6 months (ie, at the end of the CR program). RESULTS Path analyses showed that response efficacy was the sole predictor of 3-month (β = .53) and 6-month (β = .32) intentions. However, the indirect effect of baseline response efficacy on 3-month exercise behavior through intention was nonsignificant (β = −.01), whereas it was significant (β = .11) for 3-month response efficacy on 6-month exercise behavior. Self-efficacy significantly predicted 3-month (β = .36) and 6-month (β = .32) exercise behaviors, whereas 3-month intention significantly predicted 6-month exercise behavior (β = .23). CONCLUSIONS Coping appraisal variables (ie, response efficacy and self-efficacy) are potentially useful in explaining exercise behavior during home-based CR. Patients (N = 76) receiving home-based cardiac rehabilitation (CR) completed a questionnaire pre-, mid-(ie, 3 months), and post-(ie, 6 months) home-based CR. Results showed that self-efficacy significantly predicted 3- and 6-month exercise behaviors, whereas 3-month intention significantly predicted 6-month exercise behavior.

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
