背景技术背景：对即时满足的偏见与适应不良的饮食行为有关，并且与肥胖有着横断面和前瞻性的相关性。参与情景式未来思维，这涉及到心理自我投射到预先经历的未来事件，减少了超重/肥胖成人和儿童的这种偏见和能量摄入。为了研究如何将情景式未来思维纳入临床干预措施中，我们创建了一个基于网络的系统，为成人和儿童在日常生活中提供培训。OBJECTIVE：我们的研究探讨了一个基于网络的系统的技术可行性、可用性和可接受性，该系统可通过移动的设备访问，并适应情景式未来思维，用于家庭肥胖干预措施。我们从周围社区招募了20对父母-孩子（N=40），并随机分配到情景未来思维与营养信息思维对照组，以测试为期4周的基于网络的干预的可行性。父母年龄为44.1（SD 7.8）岁，BMI为34.2（SD 6.8）kg/m2。儿童年龄为11.0岁（SD 1.3），BMI百分位数为96.0（SD 1.8）。家庭每周与个案经理会面，为期4周，每天使用该系统。通过基于网络的系统收集依从性，并在干预后评估对基于网络的系统的感知接受度。在基线和干预4周后收集身体成分和饮食摄入量的测量结果。结果：所有20个家庭完成了干预，并参加了所有会议。结果显示，家长和孩子有很高的坚持基于Web的系统，并认为它是易于使用，有用的，和有帮助的。在父母（P=.65）或儿童（P=.27）的依从性方面没有发现条件之间的差异。此外，结果表明，基本的营养信息沿着情节的未来思维通过我们的基于网络的系统提供可能会减少能量摄入和weight.CONCLUSIONS：我们表明，我们的基于网络的系统是一个公认的技术和可行的实用程序。此外，研究结果提供了初步证据，表明我们的系统可以纳入以家庭为基础的治疗，针对与体重控制相关的行为。这些结果表明，使用我们的基于Web的系统在干预措施中有前途的实用程序。
BACKGROUND: The bias toward immediate gratification is associated with maladaptive eating behaviors and has been cross-sectionally and prospectively related to obesity. Engaging in episodic future thinking, which involves mental self-projection to pre-experience future events, reduces this bias and energy intake in overweight/obese adults and children. To examine how episodic future thinking can be incorporated into clinical interventions, a Web-based system was created to provide training for adults and children in their everyday lives.OBJECTIVE: Our study examined the technical feasibility, usability, and acceptability of a Web-based system that is accessible by mobile devices and adapts episodic future thinking for delivery in family-based obesity interventions.METHODS: We recruited 20 parent-child dyads (N=40) from the surrounding community and randomized to episodic future thinking versus a nutritional information thinking control to test the feasibility of a 4-week Web-based intervention. Parents were 44.1 (SD 7.8) years of age with BMI of 34.2 (SD 6.8) kg/m(2). Children were 11.0 (SD 1.3) years of age with BMI percentile of 96.0 (SD 1.8). Families met weekly with a case manager for 4 weeks and used the system daily. Adherence was collected through the Web-based system, and perceived acceptance of the Web-based system was assessed postintervention. Measurements of body composition and dietary intake were collected at baseline and after the 4 weeks of intervention.RESULTS: All 20 families completed the intervention and attended all sessions. Results showed parents and children had high adherence to the Web-based system and perceived it to be easy to use, useful, and helpful. No differences between conditions were found in adherence for parents (P=.65) or children (P=.27). In addition, results suggest that basic nutrition information along with episodic future thinking delivered through our Web-based system may reduce energy intake and weight.CONCLUSIONS: We showed that our Web-based system is an accepted technology and a feasible utility. Furthermore, results provide initial evidence that our system can be incorporated into family-based treatments targeting behaviors related to weight control. These results show promising utility in using our Web-based system in interventions.
