Many have expressed concerns about the safety and ethics of conducting suicide research, especially intense suicide research methods that expose participants to graphic depictions of suicidality. We conducted two studies to evaluate the effects of one such method called virtual reality (VR) suicide. Study 1 tested the effects of VR suicide exposure over the course of one month in participants with (n = 56) and without a history of suicidality (n = 50). Study 2 exposed some participants to VR suicide scenarios (n = 79) and others to control scenarios (n = 80). Participants were invited to complete a follow-up assessment after an average of 2 years. For both studies, the presence of suicidality post exposure was the primary outcome, with closely related constructs (e.g., capability for suicide, agitation) as secondary outcomes. Study 1 found no pre-post increases in suicidality or related variables, but revealed several significant decreases associated with small to medium effect sizes in suicide-related constructs. In Study 2, VR suicide exposure did not cause any significant increases in suicidality or related variables. Together with prior research, these findings suggest that methods involving intense suicide stimuli appear safe and consistent with utilitarian ethics.
许多人对进行自杀研究的安全性和伦理道德表示担忧,特别是那些使用可能使参与者接触到自杀相关生动描述的高强度自杀研究方法。我们进行了两项研究,评估了一种名为虚拟现实(VR)自杀的方法的效果。研究 1 在有(n=56)和无自杀史的参与者(n=50)中,测试了 VR 自杀暴露在一个月内的影响。研究 2 将一些参与者暴露于 VR 自杀场景中(n=79),将另一些参与者暴露于控制场景中(n=80)。参与者平均在 2 年后被邀请完成后续评估。对于这两项研究,暴露后的自杀意念的存在是主要结果,与自杀相关的构造(例如自杀能力、激动)是次要结果。研究 1 发现,自杀意念或相关变量没有出现前后增加,但与自杀相关结构的小到中等效应量相关的几个显著减少。在研究 2 中,VR 自杀暴露并未导致自杀意念或相关变量出现任何显著增加。结合先前的研究,这些发现表明,涉及强烈自杀刺激的方法似乎是安全的,符合功利主义伦理。
