Wise Social Psychological Interventions to Improve Outcomes of Behavioral Weight Control in Children with Obesity

我们提出了一项双臂、平行分组的随机对照试验，以测试两组相加的疗效 创新的“明智”社会心理干预--成长心态和自我肯定--至6个月 以家庭为基础的集体行为干预对肥胖儿童的体重控制，以减少体重 与单纯的行为干预相比，指数在12个月内的轨迹。 总共200名8-12岁肥胖儿童(体重指数≥第95百分位数)将被随机分为两组 条件。所有的孩子都将和他们的父母一起参加一个为期六个月的以家庭为基础的日常护理小组， 行为体重控制程序。此外，家庭随机接受社会心理干预 Condition将接受两种创新的“智慧”社会心理干预--成长心态和自我 肯定-有策略地选择和选择时机，以加强行为干预。 仍然非常需要创新的方法来增加和维持减肥 肥胖儿童。体重控制干预可能在一定程度上限制了许多儿童的成功 因为他们在试图控制体重时面临着心理障碍和威胁。其中一个 行为科学最近最激动人心的突破是看似微小但 “明智的”干预--通常由简短的练习和基于社会心理的信息组成 科学--对行为产生强有力的、积极的长期改变。这些干预措施有助于 人们通过改变他们思考自己和环境的方式而繁荣起来。我们 建议其中两项具有最强经验支持的干预措施将特别 有助于为更一致和成功的行为改变创造正确的心理环境 还有减肥。体重增长的思维模式使人们坚信，只要努力，成功是可能的。 和艰苦的工作。自我肯定通过让人们专注于他人来帮助他们应对刻板印象的威胁 自我价值的来源，从而使他们从可能确认 他们不会成功的刻板印象。因此，这种方法具有显著改进的潜力 治疗结果并减少伴随儿童肥胖症的同时和未来的发病率。 测量将在基线、3个月、6个月(行为治疗结束)和12个月时收集。 (治疗结束后6个月)。 基本假设：与随机接受常规护理的儿童相比，家庭为主的组 单独实施行为体重控制计划，儿童随机接受以家庭为基础的常规护理，组 行为体重控制计划加上明智的社会心理干预将会有显著的 体重指数在12个月内呈下降趋势。

We propose a 2-arm, parallel group, randomized controlled trial to test the efficacy of adding two innovative “wise” social psychological interventions—growth mindset and self-affirmation—to 6-month family-based, group behavioral intervention for weight control in children with obesity, to reduce body mass index trajectory over 12 months, compared to the behavioral intervention alone. A total of 200 8-12 year old children with obesity (BMI ≥ 95th percentile) will be randomized to the two conditions. All children will participate with their parents in a usual care six-month, family-based, group, behavioral weight control program. In addition, families randomized to the social psychological intervention condition will receive two innovative “wise” social psychological interventions—growth mindset and self- affirmation—strategically selected and timed to enhance the behavioral intervention. There remains a great need for innovative approaches to increase and sustain weight loss among children with obesity. Weight control interventions may be limited in their success in many children in part because of psychological barriers and threats they face when attempting to manage their weight. One of the most exciting recent breakthroughs in the behavioral sciences is the development of seemingly small but “wise” interventions—typically consisting of brief exercises and messages grounded in social psychological science—that produce powerful and positive long-term changes in behavior. These interventions help people flourish by altering the ways in which they think about themselves and their environments. We propose that two of these interventions with some of the strongest empirical support will be particularly useful in creating the right psychological landscape for more consistent and successful behavior change and weight loss. A growth mindset of body weight creates the vital belief that success is possible with effort and hard work. Self-affirmation helps people cope with stereotype threat by allowing them to focus on other sources of self-worth, thus freeing them from the distraction and anxiety of possibly confirming the stereotype that they won't succeed. As a result, this approach has the potential to substantially improve treatment outcomes and reduce the concurrent and future morbidities that accompany childhood obesity. Measures will be collected at baseline, 3 mos, 6 mos (end of the behavioral treatment), and 12 months (6 months after the end of treatment). Primary Hypothesis: Compared to children randomized to receive the usual care family-based, group behavioral weight control program alone, children randomized to receive the usual care family-based, group behavioral weight control program plus the wise social psychological interventions will have a significantly attenuated BMI trajectory over 12-months.
