Correlates of physical activity self-efficacy among breast cancer survivors.
OBJECTIVE
To determine physical activity (PA) self-efficacy correlates in breast cancer survivors.


METHODS
Mail survey of 192 breast cancer survivors.


RESULTS
Structural equation analyses demonstrated significant and direct associations for perceived PA barriers (beta=-.29), fatigue (beta=-.24), social support (beta=.12), enjoyment (beta=.12), and prediagnosis PA (beta=.11) with barriers self-efficacy. Prediagnosis PA (beta=.51), social support (beta=.26), and barriers self-efficacy (beta=.13) demonstrated direct associations with current leisure PA. Task self-efficacy analysis results were similar except perceived barriers and prediagnosis PA were not associated with task self-efficacy.


CONCLUSIONS
Multiple potential efficacy correlates exist and may vary based on the aspect of self-efficacy examined.
