ABSTRACT

Background: The loss of a loved one due to suicide can be a traumatic event associated with prolonged grief and psychological distress.

Objective: This study examined the efficacy of an Internet-based cognitive-behavioural grief therapy (ICBGT) specifically for people bereaved by suicide.

Methods: In a randomized controlled trial, 58 participants with prolonged grief disorder (PGD) symptoms who had lost a close person to suicide were randomly allocated either to the intervention group (IG) or waitlist-control group (WCG). The 5-week intervention comprised ten writing assignments in three phases: self-confrontation, cognitive restructuring, and social sharing. Symptoms of PGD, common grief reactions after suicide, depression, and general psychopathology were assessed at pre-, post-test and follow-up.

Results: Between-group effect sizes were large for the improvement of PGD symptoms in treatment completers (dppc2 = 1.03) and the intent-to-treat analysis (dppc2 = 0.97). Common grief reactions after suicide and depressive symptoms also decreased in the IG compared to the WCG (moderate to large effects). The results are stable over time. Only for general psychopathology, there was no significant time by group interaction effect found.

Conclusions: The ICBGT represents an effective treatment approach for people suffering from PGD symptoms after bereavement by suicide. Considering the effect sizes, the small treatment dose, duration, and the stability of the results, the ICBGT constitutes an appropriate alternative to face-to-face grief interventions.

基于互联网的认知行为悲伤疗法对自杀丧亲者的疗效:一项随机对照试验

摘要

背景:因自杀而失去亲人可能是与长期悲伤和心理困扰相关的创伤性事件。

目的:本研究检验了基于互联网的认知行为悲伤疗法 (ICBGT) 对自杀丧亲者的疗效。

方法:在一项随机对照试验中,58 名患有长期悲伤障碍 (PGD) 症状且因自杀而失去亲人的参与者被随机分配到干预组 (IG) 或候补名单对照组 (WCG)。为期 5 周的干预包括三个阶段的十个写作作业:自我对抗、认知重构和社交分享。PGD​​ 的症状、自杀后的常见悲伤反应、抑郁和一般精神病理学在测试前、测试后和随访中进行了评估。

结果:治疗完成者的 PGD 症状改善(d ppc2  = 1.03)和意向治疗分析(d ppc2  = 0.97)的组间效应量很大。与 WCG 相比,IG 中自杀和抑郁症状后常见的悲伤反应也有所减少(中到大影响)。结果随着时间的推移是稳定的。仅对于一般精神病理学,没有发现显着的时间组交互效应。

结论: ICBGT 代表了一种有效的治疗方法,用于治疗因自杀而丧亲后出现 PGD 症状的人。考虑到效果大小、小治疗剂量、持续时间和结果的稳定性,ICBGT 构成了面对面悲伤干预的适当替代方案。
