Using Motivational Interviewing to Improve Weight Loss Outcomes with Young Adults

描述(由申请人提供)：18-25岁的年轻人体重增加和肥胖的风险特别高，但在标准的行为减肥(BWL)计划中，他们的比例明显偏低。有人呼吁制定专门针对这一群体的计划，但几乎没有数据来指导治疗开发工作。这个应用程序的主要目的是开发和测试一个简短的、个人水平的、激励性的面试 基于这个年龄段的减肥方法；拟议的干预措施在理论上是正确的，现有的数据，以及对相关人群的大量形成工作都是正确的。参与者将是40名18-25岁的年轻人，他们的体重指数为25-40公斤/平方米，他们将被随机分为两组：基于MI的短暂行为减肥(MIBWL)或短暂行为减肥(BBWL)。两个ARM都将接受为期12周的计划，包括2个单独的面对面会议，然后是每周的BWL模块，报告关键行为，并就与目标相关的进展进行反馈，所有这些都通过电子邮件进行。在最初的两周内，MIBWL ARM的参与者将收到2个基于MI的会话，包括针对他们的行为和相对于健康标准的身体测量的个性化反馈-这些反馈将用于指导会话和增强自主动机。尽管干预者将提供核心的BWL信息，但参与者将被提供饮食、体力活动和自我监测的选项，并将 在这些领域中的每一个方面自我选择行为目标。相比之下，BBWL部门将接受两次面对面的会议，他们将在会议中获得核心BWL信息、评估措施摘要以及关于饮食、活动和自我监测的标准BWL处方。评估将在0个月、3个月和6个月进行，随后将进行离职面谈，以帮助根据需要完善方案。

DESCRIPTION (provided by applicant): Young adults 18-25 years of age are at particularly high risk for weight gain and obesity, but are dramatically underrepresented in standard behavioral weight loss (BWL) programs. There have been calls to develop programs specifically targeting this group, but little data exist to inform treatment development efforts. The primary aim of this application is to develop and test a brief, individual-level, Motivational Interviewing based approach to weight loss in this age group; the proposed intervention is routed in theory, extant data, and considerable formative work with the population of interest. Participants will be 40 young adults, 18-25 years old with a BMI of 25-40 kg/m2 who will be randomized to 1 of 2 arms: MI-based Brief Behavioral Weight Loss (MIBWL) or Brief Behavioral Weight Loss (BBWL). Both arms will receive a 12-week program, including 2 individual in-person sessions, followed by weekly BWL modules, reporting of key behaviors, and feedback on progress relative to goals, all via email. During the initial 2 weeks, participants in the MIBWL arm will receive 2 MI-based sessions, including personalized feedback on their behavior and physical measures relative to healthy standards - this feedback will be used to guide the sessions and enhance autonomous motivation. Although interventionists will present core BWL information, participants will be provided with options for diet, physical activity and self-monitoring and will self-select behavioral goals in each of these areas. In contrast, the BBWL arm will receive 2 in-person sessions in which they will receive core BWL information, a summary of their assessment measures, and standard BWL prescriptions for diet, activity and self-monitoring. Assessments will take place at 0, 3, and 6 months, followed by exit interviews to help refine the protocol as needed.
