Weight control programs that incorporate group sessions produce greater weight losses, but this has not been explored in the context of online programs. Further, counselor-crafted self-monitoring feedback is a core element of lifestyle interventions, although pre-scripted, modular feedback which does not require detailed counselor review may adequately promote weight loss. The current study explored the weight losses achieved in an online program that included facilitated group sessions, as well as outcomes when counselor-crafted self-monitoring feedback was provided.
A 2 × 2 pilot factorial randomized participants (90% women) with overweight/obesity ( = 73) to facilitated group sessions (yes/no) and type of feedback (counselor-crafted/pre-scripted, modular) within a 16-week online behavioral weight control program. Weight change outcomes were collected digitally. Treatment engagement and intervention delivery time were also tracked.
Individuals offered weekly facilitated online group sessions lost more weight (-5.3% ± 4.9%) than those receiving the same digital program without group sessions (-3.1% ± 4.0%; = 0.04). Those receiving group sessions also demonstrated significantly greater treatment engagement. Individuals receiving pre-scripted, modular feedback lost significantly more weight (-5.3% ± 4.8%) than those receiving the more traditional counselor-crafted feedback (-3.1% ± 4.1%; = 0.04), but treatment engagement did not differ between conditions. However, interventionist time required to provide feedback was markedly lower for pre-scripted than counselor-crafted feedback (1.4 vs. 3.5 h per participant over 16 weeks, respectively, = 0.01).
Incorporating weekly facilitated online group sessions significantly increased weight losses achieved in a digital lifestyle program. Further, pre-scripted, modular feedback required significantly less staff time than counselor-crafted feedback without diminishing weight losses. Thus, group sessions and pre-scripted feedback warrant consideration when designing digital lifestyle programs.
包含小组课程的体重控制计划能带来更多的体重减轻，但在线计划方面尚未对此进行探索。此外，咨询师精心设计的自我监测反馈是生活方式干预的核心要素，尽管是预先设定的模块化反馈，无需咨询师详细审核，也可能充分促进体重减轻。本研究探讨了在一个包含线上辅助小组课程的在线计划中实现的体重减轻情况，以及提供咨询师精心设计的自我监测反馈时的结果。
一项2×2的试点析因随机试验，将超重/肥胖的参与者（90%为女性，n = 73）随机分配到一个为期16周的在线行为体重控制计划中的线上辅助小组课程（是/否）和反馈类型（咨询师精心设计/预先设定的模块化）。通过数字方式收集体重变化结果。还跟踪了治疗参与度和干预实施时间。
每周参加线上辅助小组课程的个体比那些接受相同数字计划但没有小组课程的个体体重减轻更多（-5.3%±4.9% 对比 -3.1%±4.0%；P = 0.04）。参加小组课程的个体治疗参与度也显著更高。接受预先设定的模块化反馈的个体比接受更传统的咨询师精心设计反馈的个体体重减轻显著更多（-5.3%±4.8% 对比 -3.1%±4.1%；P = 0.04），但不同条件下的治疗参与度没有差异。然而，提供预先设定的反馈所需的干预人员时间明显低于咨询师精心设计的反馈（分别为16周内每位参与者1.4小时与3.5小时，P = 0.01）。
纳入每周的线上辅助小组课程显著增加了数字生活方式计划中实现的体重减轻。此外，预先设定的模块化反馈所需的工作人员时间比咨询师精心设计的反馈显著更少，且不减少体重减轻效果。因此，在设计数字生活方式计划时，小组课程和预先设定的反馈值得考虑。
