INTRODUCTION The death of a significant person through suicide is a very difficult experience and can have long-term impact on an individual's psychosocial and physical functioning. However, there are only few studies that have examined the effects of interventions in suicide survivors. In the present study, we examine an online-group intervention for people bereaved by suicide using a group-webinar. METHODS The intervention was developed based on focus groups with the target group. The cognitive-behavioral 12-module webinar-based group intervention focuses on suicide bereavement-related themes such as feelings of guilt, stigmatization, meaning reconstruction and the relationship to the deceased. Further, the webinar includes testimonial videos and psychoeducation. The suicide survivors are randomized to the intervention or the waiting list in a group-cluster randomized controlled trial. Primary outcomes are suicidality (Beck Scale for Suicide Ideation) and depression (Beck Depression Inventory-II) and secondary outcomes are symptoms of prolonged grief disorder (Inventory of Complicated Grief-German Version ), posttraumatic stress disorder ( Revised Impact of Event Scale ), stigmatization (Stigma of Suicide and Suicide Survivor ) and posttraumatic cognitions (Posttraumatic Cognitions Inventory). DISCUSSION Previous studies of Internet-based interventions for the bereaved were based on writing interventions showing large treatment effects. Little is known about the use of webinars as group interventions. Advantages and challenges of this novel approach of psychological interventions will be discussed.

通过使用网络研讨会进行自杀丧亲后的在线小组干预：随机对照试验的研究方案。

引言 重要人物因自杀身亡是一种非常艰难的经历，并且会对个人的心理社会和身体机能产生长期影响。然而，只有少数研究检查了干预措施对自杀幸存者的影响。在本研究中，我们使用小组网络研讨会检查了对自杀身亡者的在线小组干预。方法 干预是基于与目标群体的焦点小组制定的。基于认知行为的 12 模块网络研讨会小组干预侧重于与自杀丧亲相关的主题，例如内疚感、耻辱感、意义重建以及与死者的关系。此外，网络研讨会还包括推荐视频和心理教育。自杀幸存者被随机分配到组群随机对照试验中的干预或等待名单中。主要结果是自杀（Beck Scale for Suicide Ideation）和抑郁症（Beck Depression Inventory-II），次要结果是长期悲伤障碍的症状（Inventory of Complicated Grief-German Version）、创伤后应激障碍（事件量表的修订影响）、污名化（Stigma of Suicide 和 Suicide Survivor）和创伤后认知（Posttraumatic Cognitions Inventory）。讨论 以前对失去亲人的基于互联网的干预措施的研究是基于书面干预措施，显示出巨大的治疗效果。关于使用网络研讨会作为群体干预措施知之甚少。将讨论这种新的心理干预方法的优势和挑战。试验注册德国临床试验注册，DRKS00014426。注册于 2018 年 4 月 12 日。协议版本 3，2019 年 10 月 21 日。
