The purpose of this study was to test the preliminary efficacy of a Zoom-based peer coaching intervention on health and risk behaviors in young adults. A convenience sample of young adults was recruited from one U.S. university (N = 89; 73.0 percent female). Participants were randomized to one of two coaching session sequences within the framework of a stepped wedge randomized controlled trial. One experimental sequence received a control condition and a single coaching session, and the second sequence received two sessions. The intervention was a 1-hour program delivered by peer health coaches in a one-on-one setting on Zoom. The program consisted of a behavior image screen, a consultation, and goal planning. Behavioral assessments were completed after each condition. Mixed-effects models were employed to test for behavior differences after coaching sessions compared with the control condition (no coaching session) adjusting for baseline scores. Participants reported significantly higher levels of vigorous physical activity (b = 750 metabolic equivalent of task minutes, p < 0.001), a lower frequency of e-cigarette use (b = -2.1 days; p < 0.001), and a lower risk of e-cigarette susceptibility after two sessions (relative risk = 0.04, p = 0.05), and higher odds of using stress reduction techniques after one session (odds ratio = 1.4, p = 0.04). A nonsignificant trend was observed for longer weekday sleep (b = 0.4 h/night, p = 0.11) after two coaching sessions. The Zoom-based peer health coaching intervention may be an efficient way to improve vigorous physical activity, lower e-cigarette use and susceptibility, and facilitate the use of stress reduction techniques in young adults. The results observed from this preliminary study warrants further investigation using powered effectiveness trials.

基于多行为缩放的同伴健康辅导干预对年轻人的初步功效：阶梯楔形随机对照试验。

本研究的目的是测试基于 Zoom 的同伴辅导干预对年轻人健康和危险行为的初步效果。从美国一所大学招募了一个方便的年轻人样本（N = 89；73.0% 为女性）。在阶梯式楔形随机对照试验的框架内，参与者被随机分配到两个辅导课程序列之一。一个实验序列接受控制条件和一次辅导，第二个实验序列接受两次辅导。该干预是由同伴健康教练在 Zoom 上一对一进行的 1 小时项目。该计划包括行为形象筛查、咨询和目标规划。在每种情况后完成行为评估。采用混合效应模型来测试辅导课程后与调整基线分数的控制条件（无辅导课程）相比的行为差异。参与者报告的剧烈体力活动水平显着较高（b = 750 代谢当量任务分钟，p < 0.001），电子烟使用频率较低（b = -2.1 天；p < 0.001），并且电子烟的风险较低- 两次疗程后对香烟的敏感性（相对风险 = 0.04，p = 0.05），以及一次疗程后使用减压技术的几率更高（优势比 = 1.4，p = 0.04）。两次辅导课程后，观察到工作日睡眠时间延长的趋势不显着（b = 0.4 小时/夜，p = 0.11）。基于 Zoom 的同伴健康辅导干预可能是改善剧烈体育活动、降低电子烟使用和易感性以及促进年轻人使用减压技术的有效方法。从这项初步研究中观察到的结果值得使用动力有效性试验进行进一步调查。
