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

我们提出了一项 2 臂、平行组、随机对照试验来测试添加两种药物的功效 创新的“明智”社会心理干预——成长心态和自我肯定——至6个月大 以家庭为基础的团体行为干预，控制肥胖儿童的体重，以减少体重 与单独的行为干预相比，12 个月内的指数轨迹。 总共 200 名 8-12 岁肥胖儿童（BMI ≥ 95%）将被随机分配到两组 条件。所有孩子都将与父母一起参加为期六个月、以家庭为基础的团体、 行为体重控制计划。此外，家庭随机接受社会心理干预 病情将接受两种创新的“明智”社会心理干预——成长心态和自我认知 肯定——有策略地选择并适时加强行为干预。 仍然非常需要创新方法来增加和维持减肥 肥胖儿童。体重控制干预措施在许多儿童中的成功可能部分受到限制 因为他们在尝试控制体重时面临心理障碍和威胁。其中之一 行为科学最近最令人兴奋的突破是看似微小但 “明智的”干预——通常包括基于社会心理学的简短练习和信息 科学——对行为产生强大而积极的长期改变。这些干预措施有助于 人们通过改变看待自己和环境的方式来实现繁荣。我们 提出其中两项具有最强实证支持的干预措施将特别有效 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。体重成长心态创造了一个重要信念：只要努力就能成功 和努力工作。自我肯定可以让人们专注于其他事物，从而帮助他们应对刻板印象的威胁 自我价值的来源，从而使他们摆脱可能确认自我价值的分心和焦虑 他们不会成功的刻板印象。因此，这种方法有可能显着改善 治疗结果并减少儿童肥胖症并发和未来的发病率。 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：与随机接受基于家庭的常规护理的儿童相比，组 仅行为体重控制计划，儿童随机接受基于家庭、小组的常规护理 行为体重控制计划加上明智的社会心理干预将有显着的效果 12 个月内 BMI 轨迹减弱。

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.
