This study evaluated the effectiveness of a web-based stress management program among community college students that focused on increasing perceived control over stressful events.
Students (N = 257) were randomly assigned to a Present Control Intervention or a Stress-information only comparison group.
Primary outcomes were perceived stress and stress symptoms; secondary outcomes were depression and anxiety. Self-report measures were completed online at preintervention, postintervention, and three-week follow-up. Intervention effects were estimated using linear mixed models. Seventy-five percent of the sample (n = 194) completed the pretest and comprised the intent-to-treat sample.
Participants in the intervention group reported significant increases in present control, and significant decreases in all four primary and secondary outcome measures from baseline to postintervention and follow-up. Within-group effect sizes were small to medium at postintervention (mean d = -.34) and follow-up (mean d = -.49). The mean between-group effect size on the four outcome measures was d = .35 at postintervention but d = .12 at follow-up, due to unexpected decreases in distress in the comparison group.
Our online program is a cost-effective mental health program for college students. Limitations and future direction are discussed.
本研究评估了一项针对社区学院学生的基于网络的压力管理项目的有效性,该项目侧重于增强对压力事件的感知控制。
学生(N = 257)被随机分配到当前控制干预组或仅接受压力信息的比较组。
主要结局指标为感知压力和压力症状;次要结局指标为抑郁和焦虑。在干预前、干预后及三周随访时通过在线方式完成自我报告测量。使用线性混合模型估计干预效果。样本的75%(n = 194)完成了预测试,构成意向性分析样本。
干预组参与者报告称,从基线到干预后及随访时,当前控制显著增加,所有四项主要和次要结局指标均显著下降。干预后(平均d = -.34)和随访时(平均d = -.49)组内效应量为小到中等。由于比较组的痛苦意外减少,干预后四项结局指标的组间平均效应量为d = .35,但随访时为d = .12。
我们的在线项目是一项对大学生具有成本效益的心理健康项目。讨论了研究的局限性和未来方向。
