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，但在标准行为减肥（BWL）计划中的代表性明显不足。有人呼吁制定专门针对这一群体的计划，但几乎没有数据可以为治疗开发工作提供信息。这个应用程序的主要目的是开发和测试一个简短的，个人层面的，动机面试 基于此年龄组的减肥方法;建议的干预措施在理论上，现存的数据和相当大的形成性工作与感兴趣的人群路由。参与者将是40名18-25岁的年轻人，BMI为25-40 kg/m2，他们将被随机分配到两组中的一组：基于MI的短暂行为减肥（MIBWL）或短暂行为减肥（BBWL）。两组都将接受为期12周的计划，包括2个单独的面对面会议，然后是每周BWL模块，报告关键行为，以及相对于目标的进展反馈，所有这些都通过电子邮件进行。在最初的2周内，MIBWL组的参与者将接受2次基于MI的课程，包括关于其行为和身体测量相对于健康标准的个性化反馈-该反馈将用于指导课程并增强自主动机。虽然干预者将提供核心BWL信息，但将为参与者提供饮食，体力活动和自我监测的选择，并将 自我选择的行为目标。相比之下，BBWL组将接受2次面对面会议，他们将在会上接受核心BWL信息、评估指标总结以及饮食、活动和自我监测的标准BWL处方。评估将在0、3和6个月时进行，然后进行离职面谈，以根据需要帮助完善方案。 公共卫生相关性：肥胖症在美国已经达到了流行病的比例，18至25岁的年轻人的风险特别高;然而，标准的行为减肥计划并不能满足这个年龄组的需求。这项拟议中的研究旨在开发和测试一种新的方法来减轻年轻人的体重;有效的治疗可以通过降低与肥胖相关的成本来产生深远的公共卫生影响。

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. PUBLIC HEALTH RELEVANCE: Obesity has reached pandemic proportions in the United States, and young adults between 18 and 25 are at particularly high risk; yet, standard behavioral weight loss programs are not meeting this needs of this age group. The proposed research seeks to develop and test a novel approach to weight loss in young adults; effective treatment could have a profound public health impact by decreasing the costs associated with obesity as this generation ages.
