Few online interventions targeting anxiety and depression in university students are designed for universal delivery, and none for group-level delivery. This randomized controlled trial (NCT No. 04361045) examined the effectiveness of such a prevention program.
StriveWeekly is a web-based intervention designed with weekly self-guided skill modules (e.g., behavioral activation) that are synchronously delivered to all users. Student participants ( = 1,607) were recruited from one large public university, and 65.4% had no prior mental health service use. Participants were randomly assigned to 8 weeks of StriveWeekly ( = 804) or a waitlist condition ( = 803). Participants completed web-based surveys at baseline, posttest, and 3-month follow-up. The primary outcome was the self-reported Depression Anxiety and Stress Scale-21.
Piecewise linear mixed-effect models found significant group by time interactions for depression ( = -3.05, = .002), anxiety ( = -3.01, = .003), and total symptoms ( = -3.34, < .001). Relative to the waitlist, students assigned to StriveWeekly improved more from baseline to posttest (between-group = 0.18-0.21). These small effects were maintained through follow-up, and subsequently replicated by the original waitlist. The intervention was initiated by 73.0% of students in the StriveWeekly condition (modules completed: = 3.72), and 71.6% of all posttest respondents rated the intervention highly.
Findings supported StriveWeekly's effectiveness for large scale indicated prevention of anxiety and depression symptoms in university students. However, further development and research are still needed, as not all students used the intervention, reported satisfaction, or experienced improvement.

针对大学生的焦虑和抑郁的在线干预措施很少是为普遍干预而设计的，也没有针对群体水平的干预措施。本随机对照试验（NCT04361045）检验了这种预防计划的有效性。
StriveWeekly 是一种基于网络的干预措施，具有每周自我引导的技能模块（例如行为激活），这些模块同步提供给所有用户。学生参与者（n=1607）从一所大型公立大学招募而来，其中 65.4%的人以前没有使用过心理健康服务。参与者被随机分配到 8 周的 StriveWeekly（n=804）或候补名单条件（n=803）。参与者在基线、后测和 3 个月随访时完成了基于网络的调查。主要结果是自我报告的抑郁焦虑和压力量表-21。
分段线性混合效应模型发现抑郁（= -3.05，=.002）、焦虑（= -3.01，=.003）和总症状（= -3.34，<.001）的组间时间交互作用具有统计学意义。与候补名单相比，被分配到 StriveWeekly 的学生从基线到后测的改善更大（组间差异=0.18-0.21）。这些小的效果在随访中得到了维持，并随后由原始候补名单复制。在 StriveWeekly 条件下，73.0%的学生启动了干预措施（完成的模块数：=3.72），所有后测受访者中有 71.6%的人高度评价了干预措施。
研究结果支持了 StriveWeekly 在大学生中大规模有针对性地预防焦虑和抑郁症状的有效性。然而，由于并非所有学生都使用了干预措施、报告了满意度或经历了改善，因此仍需要进一步的开发和研究。
