Enhanced Internet Behavior Therapy for Treating Obesity

描述（由申请人提供）：鉴于肥胖症的患病率不断增加，而且许多成年人强烈倾向于在不使用任何药物的情况下减肥， 参加每周治疗会议，需要制定有效的 行为生活方式干预的替代方案，不需要面对面 contact.互联网提供了令人兴奋的机会，以提供行为改变 尽量减少面对面互动的干预措施。我们最近 开发并测试了一个互联网行为减肥计划， 一个互联网教育项目的随机试验， 该方案在6个月时产生了显著更好的体重减轻（4.1 kg）。我们 这项研究清楚地表明，利用互联网 替代治疗方案;然而，需要进行治疗效果研究 进一步开发一种互联网方法， 损失建议研究的目的是：（一）加强我们的互联网 开发最先进的互联网认知行为疗法的计划 （I-CBT）计划用于肥胖治疗;以及2）进行随机试验 将增强的计划与同样通过以下方式提供的最小CBT计划进行比较 互联网我们计划招募100名超重的成年人， 增强的互联网CBT或最小的互联网CBT计划。最小 I-CBT条件将被赋予链接到减肥网站，每周结构 减肥的认知行为课程，每周提示，以及在线 公告板。增强型I-CBT计划将具有这些相同的功能， 每周一次的在线小组治疗，电脑辅助的自我监控日记， 以及每周一次的治疗师个人电子邮件反馈主要结局是 体重减轻0-12个月次要结果将检查 体重变化和腰围、饮食、体力活动和社交活动的变化 支持.拟议的研究对扩大 通过使用互联网，肥胖治疗计划的受众。本研究 利用创新的方法，并扩大我们的方案研究， 开发了一种针对肥胖症的认知行为互联网治疗方法。

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.
