Social Cognitive Theory and PA after Endometrial Cancer

描述(由申请人提供)： 体力活动已被证明有益于癌症幸存者的身心健康，然而，很少有研究关注癌症幸存者人群采用体力活动生活方式的过程和决定因素。该项目的目标是研究久坐不动的子宫内膜癌幸存者接受增加体力活动干预的坚持体力活动的预测因素。本研究的具体目的是(1)在接受增加体力活动干预的久坐子宫内膜癌患者中检验体力活动采用的社会认知理论模型；(2)阐明体力活动中心肺适能和躯体感觉对自我效能的作用；(3)确定干预剂量是否与坚持体力活动有关；(4)测试坚持体力活动对子宫内膜癌患者生活质量的影响。267名静坐的I-IIa期子宫内膜癌幸存者将被招募参加这项为期6个月的研究。参与者将每两个月完成一次健康测试、问卷调查和认知测试，以评估功能能力和效率、体力活动和社会认知理论相关变量。所有参与者都将接受增加体力活动的干预，包括定制的运动处方、电话咨询和书面材料。这项研究的结果将对社会认知理论应用于体力活动提供严格的测试，并将为癌症幸存者制定有效的干预措施提供信息。

DESCRIPTION (provided by applicant): Physical activity has been shown to benefit cancer survivors' physical and emotional well-being, however, few studies have focused on the process and determinants of the adoption of physically active lifestyles in cancer survivors populations. The goal of the project is to study predictors of adherence to physical activity in sedentary endometrial cancer survivors who receive an intervention to increase their physical activity. The specific aims of the study are (1) To test a Social Cognitive Theory-based model of physical activity adoption among sedentary endometrial cancer survivors who receive an intervention to increase physical activity; (2) to elucidate the role of cardiorespiratory fitness and somatic sensations during physical activity on self-efficacy; (3) to determine whether intervention dose is related to physical activity adherence; and (4) to test the effects of adherence to physical activity on endometrial cancer survivors' quality of life. Two hundred sixty-seven sedentary Stage I-IIIa endometrial cancer survivors will be recruited to participate in this six month study. Participants will complete fitness tests, questionnaires, and cognitive tests every two months to assess functional capacity and efficiency, physical activity, and Social Cognitive Theory-related variables. All participants will receive an intervention to increase their physical activity, consisting of a customized exercise prescription, telephone counseling, and written materials. Results of the study will provide a rigorous test of Social Cognitive Theory as it is applied to physical activity, and will inform the development of effective interventions for cancer survivors.
