Physical activity (PA) has been associated with lower risk of disease recurrence and longer survival in colorectal cancer (CRC) survivors; however, less than one-third of CRC survivors are meeting PA guidelines. Interventions to promote PA in CRC survivors need to understand the most critical beliefs that influence PA behavior.
The objective of this study was to examine the strength of associations between the most common PA beliefs of CRC survivors and motivational constructs from the Theory of Planned Behavior (TPB) as well as PA behavior.
INTERVENTION/METHODS: Colorectal cancer survivors (n = 600) residing in Alberta, Canada, completed self-report questionnaires assessing medical and demographic variables, PA beliefs, constructs from the TPB, and PA behavior.
Colorectal cancer survivors identified improved fitness (69.5%), family members (67.3%), and medical/health problems (8.8%) as the most prevalent behavioral, normative, and control beliefs, respectively. All PA beliefs were significantly correlated with all TPB constructs and PA.
Physical activity interventions for CRC survivors should target many salient beliefs including behavioral, normative, and control beliefs.
Insights into the salient beliefs for PA in CRC survivors can guide nurses in developing successful strategies to promote PA in this population and likely improve quality of life and possibly disease outcomes.
体力活动（PA）与结直肠癌（CRC）幸存者疾病复发风险降低及生存期延长相关；然而，不到三分之一的CRC幸存者达到PA指南要求。促进CRC幸存者进行PA的干预措施需要了解影响PA行为的最关键信念。
本研究的目的是检验CRC幸存者最常见的PA信念与计划行为理论（TPB）中的动机结构以及PA行为之间的关联强度。
干预措施/方法：居住在加拿大艾伯塔省的600名CRC幸存者完成了自我报告问卷，评估医学和人口统计学变量、PA信念、TPB中的结构以及PA行为。
CRC幸存者分别将提高身体素质（69.5%）、家庭成员（67.3%）和医疗/健康问题（8.8%）确定为最普遍的行为、规范和控制信念。所有PA信念均与所有TPB结构和PA显著相关。
针对CRC幸存者的体力活动干预应针对许多显著信念，包括行为、规范和控制信念。
对CRC幸存者PA显著信念的深入了解可指导护士制定成功策略，以促进该人群的PA，并可能改善生活质量以及疾病结局。
