项目摘要

DESCRIPTION (provided by applicant): The vast majority of Americans do not engage in enough physical activity (PA) and rates of participation are particularly low for women aged 45 years or older. The association between regular PA and reduced risk for breast cancer is well established with some estimates suggesting that physically active women may be as much as 80% less likely to develop breast cancer compared to physically inactive women. For this reason, there is great public health incentive to increase PA rates among middle-aged women. How best to motivate PA behavior is an area of study in need of a more concrete theoretical framework. Research conducted across several broad areas of psychology including, clinical, social, and health have consistently implicated self-monitoring as an effective intervention for increasing participation in health behaviors (i.e., PA). In terms of what aspects of the PA experience might be most useful to self-monitor, recent work suggests that among the middle-aged female demographic, increased awareness of the immediate benefits PA holds for everyday life (i.e., affect improvement) may be important. The PA-affect relationship may be an especially relevant focus as more favorable affect during and immediately following exercise has been linked to subsequently greater PA intentions and more frequent exercise behavior over time. A crucial limitation of past work studying the PA-affect relationship has been the inherent inability to study the relationship using an experimental design. A specific aim of the proposed study is to address this gap in the literature. Although it is not possible to randomly assign an individual to have a pre-specified affective response to PA, it is possible to randomly assign an individual to attend to a pre-specified aspect of the PA experience through the use of self-monitoring. Specifically, this study will assign women aged 40-60 to self-monitor (by completing daily PA-journals) aspects of the PA experience that are psychological in nature (i.e., affect), physiological in nature (e.g., calories burned etc.), or neutral (i.e., self-reportonly the activity that was performed). The self-monitoring intervention will take part during first mont of study participation only - thereafter, participants will complete follow-up assessments at 3 and 6-months post-baseline that will assess levels of PA participation and other psychosocial variables. In addition to testing the effectiveness of the self- monitoring intervention, an exploratory aim of this project is to examine the mechanisms by which the self- monitoring interventions influenced behavior change and maintenance through a meditational analysis utilizing constructs from a novel theoretical model of PA, the Theory of Physical Activity Maintenance (PAM). The long-term objectives of this project are (1) to better understand the factors that motivate and maintain PA behavior among middle-aged women; and (2) to inform the design of future PA-based interventions and clinical trials focused on promoting women's health generally, and breast cancer prevention efforts specifically. ! ! !

描述（由申请人提供）：绝大多数美国人没有进行足够的体育锻炼（PA），而参与率对于45岁或以上的妇女来说尤其低。常规PA与乳腺癌风险降低之间的关联良好，一些估计表明，与身体不活跃的女性相比，身体活跃的女性患乳腺癌的可能性可能低高80％。因此，有很大的公共卫生动机可以提高中年妇女的PA率。如何最好地激励PA行为是一个需要更具体的理论框架的研究领域。在包括临床，社会和健康在内的几个广泛的心理学领域进行的研究一直牵涉到自我监控，作为增加对健康行为参与的有效干预措施（即PA）。就PA经验的哪些方面可能对自我监控最有用，最近的工作表明，在中年女性人群中，人们对PA对日常生活的直接利益的认识提高了（即影响改善）可能很重要。 PA与PA的关系可能是一个特别相关的重点，因为在锻炼过程中的影响更大，随后随后的PA意图和随着时间的推移更加频繁的运动行为是相关的。过去研究PA-影响关系的关键局限性是使用实验设计研究这种关系的固有无力。拟议的研究的一个具体目的是解决文献中的这一差距。尽管无法随机分配个人对PA具有预先指定的情感反应，但可以通过使用自我监控来随机分配个人参加PA体验的预先指定方面。具体而言，这项研究将把40-60岁的妇女分配给PA体验的自我监测者（通过完成每日PA-Journals）本质上是心理学（即情感），生理学本质上（例如，卡路里燃烧等）或中性（即自我报告的活动）。自我监控干预仅在研究的第一个蒙特参与期间进行 - 此后，参与者将在3和3和 6个月后，将评估PA参与水平和其他社会心理变量的水平。除了测试自我监测干预措施的有效性外，该项目的探索目的是检查自我监测干预措施通过使用新颖的PA理论模型的构造，体育活动理论维持理论（PAM）来影响行为改变和维护的机制。该项目的长期目标是（1）更好地了解激励和维持中年妇女PA行为的因素；（2）为未来的基于PA的干预措施和临床试验的设计提供信息，重点是促进妇女健康和乳腺癌预防工作。呢呢呢
