Mobile Application for Guided Imagery to Address Smoking, Diet and Physical Activ

描述（由申请人提供）：目前，女性吸烟人数接近男性，仅在美国就有大约2700万女性吸烟者。肺癌是妇女癌症死亡的主要原因，每年有18万多名妇女死于与吸烟有关的其他疾病。女性报告说，戒烟的困难更大，而且比男性更容易复发。此外，烟草使用与不良的饮食习惯和缺乏体育活动有关，92%的吸烟者报告至少有一个其他健康风险因素。 多种行为风险因素的存在大大增加了发展许多急性和慢性疾病的风险（例如，MI、COPD等）。对体重增加、负面身体形象和低自我效能感的担忧可能是影响体重相关女性吸烟者戒烟的关键因素。这些吸烟者对自己的身体不太满意，自尊心较低，比不吸烟者更担心超重。研究结果提示，针对体重关注、身体意象和自我效能感对体重关注女性吸烟者进行戒烟可能是一种有效的干预策略。一种认知方法，引导图像，已成功地用于单独的调查线，以解决身体活动，饮食和戒烟。然而，引导意象还没有被用来针对体重有关的妇女吸烟或同时针对吸烟，饮食和运动行为在一个单一的干预。这项拟议中的研究将是第一个创建一个基于理论的指导性图像干预，以帮助体重相关的女性吸烟者戒烟。虽然图像是行为改变的有效治疗工具，但交付模式通常是面对面的，限制了基于图像的指导干预措施在大规模人群中的传播。通过智能手机提供的移动的健康应用程序（移动的应用程序）提供了一个独特的渠道，通过该渠道可以分发基于图像的干预措施。使用移动的应用程序提供了一种创新的方法来解决体重相关女性戒烟努力中涉及的多种行为，并有可能接触到大量女性吸烟者。如果成功，一个移动的应用程序， 引导图像也可用于解决其他健康行为。本项目的目的是开发和测试使用引导图像的移动的保健应用程序的可行性，以便在关注体重的女性吸烟者中促进戒烟。我们还将收集参与者在接受图像干预之前和之后的饮食和身体活动行为的数据。这项研究的结果将为我们将来的随机对照试验做好准备，以测试多行为引导图像移动的健康应用程序与单一戒烟图像移动的健康应用程序的疗效和成本效益。

DESCRIPTION (provided by applicant): Tobacco use among women now approaches that of men, with approximately 27 million women smokers in the United States alone. Lung cancer is the leading cause of cancer death among women, and more than 180,000 women die of other illnesses linked to smoking annually. Women report greater difficulties quitting smoking and are more likely to relapse than men. In addition, tobacco use co-varies with poor dietary practices and lack of physical activity, with 92% of smokers reporting at least one other health risk factor. The presence of multiple behavioral risk factors greatly increases the risk of developing many acute and chronic conditions (e.g., MI, COPD, etc.). Concerns surrounding weight gain, negative body image, and low self-efficacy, may be key factors affecting smoking cessation among weight-concerned women smokers. These smokers are less satisfied with their bodies, have lower self-esteem, and are more concerned about becoming overweight than non-smokers. These findings suggest that targeting weight concern, body image and self-efficacy to quit with weight-concerned women who smoke may be an effective intervention strategy. One cognitive approach, guided imagery, has been successfully employed in separate lines of inquiry to address physical activity, diet and smoking cessation. However, guided imagery has not been employed to target weight concerned women who smoke or to simultaneously target smoking, diet, and exercise behavior in a single intervention. The proposed study would be the first of its kind to create a theory-based, guided imagery intervention to assist weight-concerned women smokers to quit. While imagery is an effective therapeutic tool for behavior change, the mode of delivery has generally been in-person, limiting the dissemination of guided imagery-based interventions to large populations. Mobile health applications (mobile apps) delivered via smart phones offer a unique channel through which to distribute imagery-based interventions. The use of a mobile app offers an innovative approach to addressing the multiple behaviors involved in smoking cessation efforts of weight-concerned women, and has the potential to reach large numbers of women smokers. If successful, a mobile application for guided imagery could be used to address other health behaviors as well. The present project aims to develop and test the feasibility of a mobile health application using guided imagery in order to increase smoking cessation among a population of weight-concerned women smokers. We will also collect data on the eating and physical activity behaviors of our participants before and after receiving the imagery intervention. Results of this study will prepare us for a future randomized controlled trial to test the efficacy and cost-effectiveness of a multi-behavioral, guided imagery mobile health application versus a single smoking cessation imagery mobile health application.
