DESCRIPTION (provided by applicant): Intensive behavioral interventions are needed to stem the obesity epidemic. Unfortunately, effective implementation of behavioral therapies is limited by the lack of an accurate system for measuring behavior and delivering immediate reinforcement. This SBIR Phase I proposal focuses on testing the feasibility of an innovative wireless platform for shaping key weight loss and maintenance behaviors, and using electronic media (TV) as reinforcement. This general idea is referred to here as "Behavioral Pay-Per-View". Behavioral measurement is based on combinations of (a) self-monitoring of key weight loss and maintenance behaviors via easy-to-use software that runs on a cell phone and (b) automatic sensors embedded in weight loss implements such as scales, pedometers, etc. Engagement in targeted behaviors such as daily measurement of body weight, careful portion estimation through weighing of foods, and regular self-monitoring of dietary intake result in immediate reinforcement through accretion of points exchangeable for access to electronic media. Because all media access in the home is earned through engagement in targeted behaviors, interventions using the technology further serve to reduce total media usage, which is a critical environmental factor related to obesity. The use of automatic sensors and usability-engineered software reduces the burden to users attempting to follow a prescribed behavior regimen. The specific aims of this proposal are: (1) develop a usability test bed of sensors and media regulators. The test bed will allow testing of the devices in situations approximating everyday use; (2) conduct iterative discount usability studies with n=15 adults to make the technology functional in the field, and; (3) conduct single-subjects experiments on the use of the technology during a 4-month, standard behavioral weight loss program in n=10 overweight adults. Successful completion of these aims will enable randomized clinical trials in Phase II and provide important data on using media access to reinforce key weight loss and maintenance behaviors in adults. The development of inexpensive clinically-validated behavioral interventions to treat and prevent obesity is a pressing National health care priority. Obesity is epidemic. The proposed research is for the testing of an innovative technology to change key behaviors related to successful weight loss and maintenance in adults.

描述（由申请人提供）：需要进行强化行为干预以阻止肥胖症流行。不幸的是，行为疗法的有效实施受到缺乏衡量行为和立即加强的精确系统的限制。该SBIR I期建议着重于测试创新无线平台来塑造关键减肥和维护行为的可行性，并使用电子媒体（TV）作为增强。此一般想法在这里称为“行为付费按次观看”。行为衡量基于（a）通过易于使用的软件对（a）自我监控对手机上运行的软件进行自我监控以及（b）嵌入体重损失的自动传感器以及（b）自动降低工具等自动传感器，例如尺度，计数器等。通过积聚可交换的点来访问电子媒体来加强。由于房屋中的所有媒体访问都是通过参与目标行为而获得的，因此使用该技术的干预措施进一步减少了媒体使用的全部用法，这是与肥胖有关的关键环境因素。自动传感器和可用性工程软件的使用减轻了试图遵循规定行为方案的用户的负担。该提案的具体目的是：（1）开发传感器和媒体调节器的可用性测试床。测试床将允许在近似日常使用的情况下测试设备； （2）对n = 15名成年人进行迭代折扣可用性研究，以使该技术在现场发挥作用，并且； （3）在n = 10个超重成年人中进行4个月的标准行为减肥计划中，进行了有关该技术使用的单受试者实验。这些目标的成功完成将使II阶段的随机临床试验能够在使用媒体访问方面加强成人关键的减肥和维持行为的重要数据。廉价的临床验证行为干预措施以治疗和预防肥胖是迫切的国家医疗保健优先事项。肥胖是流行病。拟议的研究是用于测试创新技术，以改变与成年人成功减肥和维护有关的关键行为。
