The degree to which breast cancer survivors use behavioral processes of change has not been investigated. Additionally, the relationship between behavioral processes and other theory-based mediators of adult physical activity behavior has not been extensively studied among breast cancer survivors. The objectives of this study were to: (1) determine the extent to which breast cancer survivors use behavioral processes associated with physical activity behavior change, and (2) examine the inter-relationships between behavioral processes, self-efficacy, and physical activity behavior among breast cancer survivors.
Sixty-nine breast cancer survivors completed surveys examining behavioral processes and exercise-specific self-efficacy. Six months later they completed a self-report physical activity questionnaire.
Findings showed the majority of breast cancer survivors did not use approximately half of the behavioral processes on a regular basis, and self-efficacy completely mediated the relationship between behavioral processes and physical activity.
Health care professionals may help enhance self-efficacy and ultimately increase physical activity behavior in breast cancer survivors by teaching behavior skills such as enlisting social support.
乳腺癌幸存者对行为改变过程的运用程度尚未得到研究。此外，在乳腺癌幸存者中，行为过程与其他成人体育活动行为的理论中介变量之间的关系也没有得到广泛研究。本研究的目的是：（1）确定乳腺癌幸存者使用与体育活动行为改变相关的行为过程的程度，（2）检验乳腺癌幸存者中行为过程、自我效能与体育活动行为之间的相互关系。
69 名乳腺癌幸存者完成了调查，调查内容包括行为过程和特定于运动的自我效能。6 个月后，他们完成了一份自我报告的体育活动问卷。
研究结果表明，大多数乳腺癌幸存者并没有定期使用大约一半的行为过程，而且自我效能完全中介了行为过程与体育活动之间的关系。
卫生保健专业人员可以通过教授行为技能，如争取社会支持，来帮助提高自我效能，并最终增加乳腺癌幸存者的体育活动行为。
