项目摘要

Abstract Adults attempting weight loss through lifestyle modification (LM) typically find maintenance of behavior change difficult. Outcomes might be improved if participants are provided with sustained sources of accountability and support and ongoing opportunities to reflect with others on goal progress. This study proposes that sharing digital data (i.e., body weight from wireless scale, physical activity from wearable sensor, and dietary intake from smartphone app) with other parties has the potential to improve long-term weight loss. The benefit of device data sharing has not yet been rigorously tested, and traditional LM programs do not yet incorporate digital data sharing in a systematic way. The proposed study will enroll adults (N = 320) with overweight/ obesity in a 24-month LM program and instruct them to use digital tools for self-monitoring of weight, physical activity, and eating on a daily basis. Groups will meet face-to-face weekly in months 1-3 to initiate weight loss. In months 4-24, intervention contact will be remote and will include the following: quarterly group meetings held via videoconference; brief phone calls with the coach held twice per quarter; and monthly text messages with the coach, with a small group of fellow group participants, and with a friend or family member outside of the program. A 2 x 2 x 2 factorial design will test the independent effects of three types of data sharing partnerships: Coach Share, Group Share, and Friend/Family Share. Half of the participants will receive Coach Share and half will not; half will receive Group Share and half will not; and half will receive Friend/Family Share and half will not. In Coach Share, the behavioral coach will view digital self-monitoring data throughout the program and will directly address data observations during intervention contacts. In Group Share, participants in a given LM group will view each other’s self-monitoring data in their small-group text messages. In Friend/Family Share, a friend or family member outside of the group will view the participant’s data via automated text message. Each party with whom data are shared will be trained to respond by eliciting reflection from the index participant on his/her goal progress, which is a key component of self-regulation, and supporting the participant’s motivation to meet program goals. Amount of intervention contact between the participant and each party (Coach, Group, Friend/Family) will be comparable across treatment conditions, isolating the effects of data sharing components. Outcomes will be measured at months 0, 6, 12, and 24. The study will determine if Coach Share, Group Share, and Friend/Family Share each improve long-term weight loss, PA, and calorie intake (i.e., outcomes will be compared for participants who are randomized to engage in that data sharing partnership, versus those who are not). The study also will examine if effects are additive when participants are assigned to engage in more than one type of data sharing partnership. Mediators and moderators of intervention effects will be examined. As digital technology makes data sharing increasingly feasible, it is critical to determine how to optimize these partnerships to improve long-term outcomes in LM.
抽象的 尝试通过生活方式改变(LM)减肥的成年人通常会发现行为改变可以维持 如果提供持续的问责来源,结果可能会得到改善。 支持和与他人反思目标进展的持续机会。 数字数据(即无线秤的体重、可穿戴传感器的身体活动以及饮食摄入量 来自智能手机应用程序)与其他方合作有可能改善长期减肥。 设备数据共享尚未经过严格测试,传统的LM程序尚未纳入 拟议的研究将招募超重/的成年人(N = 320)。 在为期 24 个月的 LM 计划中,指导他们使用数字工具自我监测体重、身体状况 小组将在第 1-3 个月每周进行一次面对面的活动和饮食,以开始减肥。 在第 4 至 24 个月中,干预接触将是远程的,包括以下内容: 举行季度小组会议 通过视频会议;每季度与教练进行两次简短的电话会议以及每月一次的短信; 教练与一小群团体参与者以及团体之外的朋友或家人一起 2 x 2 x 2 因子设计将测试三种类型的数据共享的独立效果。 合作伙伴:教练分享、团体分享和朋友/家人分享 一半的参与者将获得教练。 分享,一半不会;一半将获得团体分享,一半不会;一半将获得朋友/家人分享; 在 Coach Share 中,行为教练将在整个过程中查看数字自我监控数据。 计划并将在干预接触期间直接处理数据观察,参与者。 给定LM组中的每个人都会在小组短信中查看彼此的自我监控数据。 朋友/家人共享,群组外的朋友或家人将通过以下方式查看参与者的数据 自动短信。共享数据的每一方都将接受培训以引发回应。 指数参与者对其目标进展的反思,这是自我监管的关键组成部分,以及 支持实现参与者计划目标的动机 参与者之间的干预接触量。 并且各方(教练、团体、朋友/家人)在参与者的治疗条件上具有可比性, 隔离数据共享组件的影响将在第 0、6、12 和 24 个月进行衡量。 研究将确定教练分享、团体分享和朋友/家人分享是否都能改善长期体重 损失、PA 和卡路里摄入量(即,将比较随机参与的参与者的结果) 该研究还将检查效果是否具有累加性。 当参与者被分配参与不止一种类型的数据共享伙伴关系时。 随着数字技术使数据共享日益增多,干预效果的调节因素将受到检验。 在可行的情况下,确定如何优化这些伙伴关系以改善LM的长期成果至关重要。
