Abstract
In Brief OBJECTIVE: Limited research has identified theoretical correlates of physical activity (PA) change in patients not receiving cardiac rehabilitation. The purpose of the present study was to determine whether changes in self-efficacy, PA intention, perceived severity and susceptibility, and PA benefits/barriers were associated with changes in PA over a 12-month period in these patients. METHODS: Patients (N = 555) not attending cardiac rehabilitation completed a psychosocial questionnaire in hospital and 6 and 12 months after hospitalization for a cardiac event. RESULTS: Hierarchical regression analyses showed that the increase in PA from baseline to 6 months was significantly related to an increase in self-efficacy and PA intentions and a decrease in the impact of health-related barriers. Furthermore, the decrease in PA from 6 to 12 months was significantly related to a decrease in health-related benefits and PA intentions and an increase in time and health-related barriers. Finally, the increase in PA from baseline to 12 months was significantly related to an increase in health-related benefits and intentions and a decrease in health-related barriers. CONCLUSIONS: Changes in PA levels over a 12-month period were associated with changes in various theoretical variables. Interestingly, the associations among these variables with PA varied as a function of time after hospitalization. Five hundred fifty-five cardiac patients completed a questionnaire in hospital, and 6 and 12 months after hospitalization. Results showed that changes in physical activity throughout the 12-month period were significantly associated with changes in self-efficacy, physical activity intentions, physical activity barriers, and physical activity benefits.

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
