ABSTRACT

Suicidal individuals rarely seek help and receive professional psychological intervention on their initiative. Internet-based cognitive behavioral therapy(iCBT) can increase availability and reduce stigma compared to face-to-face interventions for suicide.However, conclusions about the effectiveness of iCBT on suicide are controversial. The review aimed to determine the effectiveness of iCBT on reducing suicidal ideation (primary outcomes) and other outcomes related to suicide like suicide attempts(secondary outcomes). PubMed, the Cochrane Library, EMBASEwere searched up to March 2020 for RCTs of iCBT which aimed to reduce suicide.The potential bias was assessed by the Cochrane risk of bias tool. Data analyses wereperformed by RevMan5.3.Four studies meeting the eligibility criteria were included which reported data on a total of 1225 participants. We found iCBT was associated with reducing an individual’s suicidal ideation, and first indications suggest that the treatment effect might be even more pronounced in the short term and in adults.Additionally, there was insufficient evidence to prove its effectiveness in reducing suicide attempts and suicide death.Overall, iCBT can overcome the disadvantages of traditional interventions and show promise on suicidal ideation. While ensuring safety and ethics, further studies are warranted, focusing on suicide specific behavior like suicide attempts.

摘要

有自杀倾向的人很少主动寻求帮助和接受专业的心理干预。与面对面的自杀干预相比，基于互联网的认知行为疗法 (iCBT) 可以增加可用性并减少耻辱感。然而，关于 iCBT 对自杀的有效性的结论存在争议。该评价旨在确定 iCBT 在减少自杀意念（主要结果）和与自杀相关的其他结果（如自杀未遂）（次要结果）方面的有效性。截至 2020 年 3 月，PubMed、Cochrane 图书馆、EMBASE 搜索了旨在减少自杀的 iCBT 随机对照试验。通过 Cochrane 偏倚风险工具评估潜在偏倚。数据分析由 RevMan5.3 执行。包括四项符合资格标准的研究，报告了总共 1225 名参与者的数据。我们发现 iCBT 与减少个体的自杀意念有关，初步迹象表明，治疗效果在短期内和成人中可能更加明显。此外，没有足够的证据证明其在减少自杀企图和自杀死亡方面的有效性.总体而言，iCBT 可以克服传统干预措施的缺点，并显示出对自杀意念的希望。在确保安全和道德的同时，还需要进一步研究，重点关注自杀未遂等特定的自杀行为。没有足够的证据证明其在减少自杀企图和自杀死亡方面的有效性。总体而言，iCBT 可以克服传统干预措施的缺点，并显示出对自杀意念的希望。在确保安全和道德的同时，还需要进一步研究，重点关注自杀未遂等特定的自杀行为。没有足够的证据证明其在减少自杀企图和自杀死亡方面的有效性。总体而言，iCBT 可以克服传统干预措施的缺点，并显示出对自杀意念的希望。在确保安全和道德的同时，还需要进一步研究，重点关注自杀未遂等特定的自杀行为。
