Self-efficacy and physical activity among cardiac rehabilitation graduates: The moderating role of social support
Bibliographic record
Abstract
Social support and barrier self-efficacy are important variables for adults who have followed a cardiac rehabilitation program, but few studies have examined their interacting effects. Therefore, the purpose of this study was to examine whether social support moderated the relationship between barrier self-efficacy and physical activity in adults post-cardiac rehabilitation. Participants (N = 57, Mage = 63, 85.5% males, 14.5% females) were adults who previously completed a cardiac rehabilitation program. They wore an accelerometer (Actigraph GT3X) for a 9-day period and valid 7-day moderate to vigorous physical activity data were retained for the analyses. Participants completed a questionnaire assessing barrier self-efficacy and social support. Separate moderation analyses were conducted to examine if social support from either family, peers or spouse moderated the relationship between barrier self-efficacy and physical activity. Peer social support was a significant moderator of the self-efficacy - physical activity relationship (B = -2.43, 95% CI = -2.82, -0.13, R2-change = 9%). At low levels of self-efficacy, participants with high social support from peers had greater physical activity levels than participants with low social support. However, when self-efficacy was high, physical activity levels were similar across the peer social support spectrum. Social support from family (B = -1.67, 95% CI= -2.46, 0.72, R2-change = 3%) and spouse (B = -0.96, 95% CI= -2.44, 0.31, R2-change = 3%) were not significant moderators. Cardiac rehabilitation graduates with low levels of barrier self-efficacy appear to be more physically active when they report greater social support from peers. Future post-cardiac rehabilitation interventions could utilize the power of peers to help increase physical activity levels of individuals with lower confidence and motivation to overcome physical activity-related barriers.

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.
