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.

我们提出了一个2臂，平行组，随机对照试验，以测试增加两个 创新的“智慧”社会心理干预-成长心态和自我肯定-至6个月 以家庭为基础的团体行为干预，用于控制肥胖儿童的体重，以减少体重 12个月的指数轨迹，与单独的行为干预相比。 共200例8-12岁肥胖儿童（BMI ≥第95百分位数）将随机分配至两组 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家庭护理小组， 行为体重控制计划另外，将家庭随机分配到社会心理干预组 条件将得到两个创新的“明智”的社会心理干预-成长心态和自我， 肯定策略选择和时间，以加强行为干预。 仍然非常需要创新的方法来增加和维持体重减轻， 肥胖儿童。体重控制干预措施在许多儿童中的成功可能有限， 因为他们在试图控制体重时面临心理障碍和威胁。之一 行为科学最近最令人兴奋的突破是发展了一种看似很小， “明智的”干预-通常包括简短的练习和基于社会心理学的信息。 科学-产生强大和积极的长期行为变化。这些干预措施有助于 人们通过改变他们对自己和环境的思考方式而繁荣。我们 我建议，这些干预措施中有两个具有最强有力的经验支持， 有助于创造正确的心理环境，以实现更一致和成功的行为改变 和减肥。体重增长的心态创造了一个重要的信念，即成功是可能的努力 努力工作自我肯定通过让人们关注他人，帮助他们科普刻板印象的威胁。 自我价值的来源，从而使他们摆脱分心和焦虑，可能确认 他们不会成功。因此，这种方法有可能大大改善 治疗结果，并减少伴随儿童肥胖的并发症和未来的发病率。 将在基线、3个月、6个月（行为治疗结束）和12个月时收集测量结果 （治疗结束后6个月）。 主要假设：与随机接受常规护理的儿童相比， 行为体重控制计划单独，儿童随机接受常规护理家庭为基础，组 行为体重控制计划加上明智的社会心理干预， 在12个月内BMI轨迹变缓。
