■这项荟萃分析旨在评估基于互联网的自助干预措施对青少年和大学生心理健康的影响。
我们对随机对照试验(RCT)进行了系统评价,该试验调查了基于互联网的自助干预措施,旨在减轻焦虑和抑郁等心理健康症状,以及管理高水平的压力,在青少年和大学生中。我们的搜索跨越了包括WebofScience在内的数据库,PubMed,科克伦图书馆,和Embase,直到11月1日,2022年。必须强调的是,我们的重点是对症状的评估(持续的结果),而不是特定精神障碍的诊断。使用R版本4.3.1进行荟萃分析。效应大小测量为标准化平均差(SMD),和随机效应模型用于汇集来自符合条件的随机对照试验的数据。进行了亚组分析,以检查基于样本类型等因素的干预效果的变化,干预方式,导向型,和干预持续时间。
■荟萃分析基于25个比较,涉及4480名参与者。与对照组(n=2125)相比,接受干预的参与者(n=2355)报告焦虑症状显著减轻,抑郁症,和压力,以及生活质量的显著提高。具体来说,对于抑郁症,我们观察到中度干预效果(SMD=-0.42,95%CI:-0.56,-0.27),在生活质量方面也观察到了类似的模式(SMD=0.36,95CI:0.22,0.49)。对焦虑(SMD=-0.35,95%CI[-0.48,-0.22])和应激(SMD=-0.35,95%CI[-0.51,-0.20])的干预效果较小。鉴于显著的异质性,对焦虑和抑郁进行亚组分析,考虑样品类型等因素,干预方法,和干预持续时间。值得注意的是,与青少年相比,大学生在缓解焦虑和抑郁方面的获益更大。长期干预(>8周)在减少焦虑和抑郁方面特别有效。此外,第三波认知行为疗法(CBT)在两种结局指标中均显示出明显的干预效果,而指导的存在并没有显著影响结果.
这项荟萃分析强调了基于互联网的自助计划在缓解青少年和大学生心理障碍症状方面的积极影响。然而,必须承认现有证据显示不一致和局限性。因此,使用严格方法的进一步研究对于验证和扩大本荟萃分析的发现是必要的.
UNASSIGNED: This meta-analysis aims to evaluate the impact of Internet-based self-help interventions on the mental health of adolescents and college students.
UNASSIGNED: We conducted a systematic review of randomized controlled trials (RCTs) that investigated Internet-based self-help interventions aiming to mitigate mental health symptoms such as anxiety and depression, as well as managing high levels of stress, among adolescents and college students. Our search spanned databases including Web of Science, PubMed, Cochrane Library, and Embase, up until November 1st, 2022. It is essential to emphasize that our focus was the evaluation of symptoms (continuous outcomes), rather than the diagnosis of specific mental disorders. The meta-analysis was performed using the R version 4.3.1. The effect size measure was the standardized mean difference (SMD), and random-effects models were used to pool data from eligible RCTs. Subgroup analyses were carried out to examine variations in intervention effects based on factors such as sample type, intervention modality, guidance type, and intervention duration.
UNASSIGNED: The meta-analysis was based on 25 comparisons involving a total of 4480 participants. In comparison to the control group (n = 2125), participants receiving interventions (n = 2355) reported significant reductions in symptoms of anxiety, depression, and stress, along with a significant improvement in quality of life. Specifically, for depression, we observed moderate intervention effects (SMD = -0.42, 95 % CI: -0.56, -0.27), and a similar pattern was seen for quality of life (SMD = 0.36, 95%CI: 0.22, 0.49). Small intervention effects were found for anxiety (SMD = -0.35, 95 % CI [-0.48, -0.22]) and stress (SMD = -0.35, 95 % CI [-0.51, -0.20]). Given significant heterogeneity, subgroup analyses were conducted for anxiety and depression, considering factors such as sample type, intervention method, and intervention duration. Notably, college students experienced more significant benefits in both anxiety and depression alleviation compared to adolescents. Longer interventions (>8 weeks) were particularly effective in reducing anxiety and depression. Additionally, third-wave cognitive-behavioral therapy (CBT) showed pronounced intervention effects in both outcome measures, while the presence of guidance did not notably influence results.
UNASSIGNED: This meta-analysis underscores the positive impact of Internet-based self-help programs in alleviating the symptoms of psychological disorders among adolescents and college students. However, it is crucial to acknowledge that the available evidence exhibits inconsistencies and limitations. Therefore, further research utilizing rigorous methodologies is necessary to verify and broaden the findings of this meta-analysis.
