Enhanced Internet Behavior Therapy for Treating Obesity

描述(申请人提供)：鉴于肥胖症的流行日益普遍，以及许多成年人强烈倾向于在没有 每周参加治疗会议，需要制定有效的治疗方案 行为生活方式干预的替代方案需要更少的面对面 联系。互联网提供了令人兴奋的机会来改变人们的行为 尽量减少面对面互动的干预措施。我们最近做了 开发并测试了一项互联网行为减肥计划，与 一个互联网教育项目在随机试验中发现了行为 该计划在6个月时体重减轻(4.1公斤)明显好于对照组。我们的 研究清楚地确定了使用互联网交付的潜力 替代治疗方案；然而，治疗效果研究是需要的 进一步开发一种互联网方法，促进长期体重 损失。建议研究的目的是：i)加强互联网 开发最先进的互联网认知行为疗法的计划 (I-CBT)肥胖症治疗计划；以及2)进行随机试验 将增强计划与也通过以下方式提供的最低CBT计划进行比较 互联网。我们建议招募100名超重成年人并随机分配 增强的互联网CBT或最小的互联网CBT计划。最小的 I-CBT条件将被提供到减肥网站的链接，每周结构化 关于减肥的认知-行为课程，每周的提示，和一个在线 公告牌。增强的i-CBT计划将具有这些相同的功能以及 每周一次的在线团体治疗，电脑辅助的自我监控日记， 以及每周一次来自治疗师的个人电子邮件反馈。主要结果是 体重减轻0-12个月。次要结果将检查以下模式 体重变化和腰围、饮食、体力活动和社交的变化 支持。这项拟议的研究对扩大 通过互联网为肥胖治疗方案服务的受众。本研究 采用创新的方法，并扩大我们对 开发一种认知行为互联网治疗肥胖症。

DESCRIPTION (provided by applicant): Given the increasing prevalence of obesity and fact that many adults have a strong preference to lose weight without attending weekly treatment meetings, there is need to develop effective alternatives to behavioral lifestyle interventions requiring less face-to-face contact. The Internet offers exciting opportunities to deliver behavior change interventions that minimize face-to-face interaction. We have recently developed and tested an Internet behavioral weight loss program compared with an Internet educational program in a randomized trial and found the behavioral program produced significantly better weight losses (4.1 kg) at 6 months. Our study clearly establishes the potential for using the Internet to deliver alternative treatment programs; however, treatment efficacy research is needed to further develop an Internet approach that will promote longer-term weight loss. The objectives of the proposed study are I) to enhance our Internet program to develop a state of the art Internet Cognitive-Behavior Therapy (I-CBT) program for obesity treatment; and 2) to conduct a randomized trial comparing the enhanced program with a Minimal CBT program also delivered via the Internet. We propose to recruit 100 overweight adults and randomly assign them to Enhanced Internet CBT or Minimal Internet CBT programs. The Minimal I-CBT condition will be given links to weight loss websites, weekly structured cognitive-behavioral lessons for weight loss, weekly prompting, and an on-line bulletin board. The Enhanced I-CBT program will have these same features plus weekly on-line group therapy sessions, computer-aided self-monitoring diaries, and weekly individual e-mail feedback from a therapist. The primary outcome is weight loss from 0-12 months. Secondary outcomes will examine patterns of weight change and changes in waist, diet, physical activity, and social support. The proposed research has significant implications for expanding the audience served by obesity treatment program by using the Internet. This study utilizes an innovative approach and extends our programmatic research on the development of a cognitive-behavioral Internet treatment for obesity.
