OBJECTIVE The first randomized controlled trial of psychological first aid (PFA) was conducted, using crime victims as participants. For study Aim 1, investigators tested whether paraprofessional victim advocates could be trained to deliver PFA to crime victims. For study Aim 2, investigators tested the effect of PFA delivery on victims' psychiatric (i.e., symptoms of PTSD, somatization, depression, anxiety, and substance use) and adaptive functioning outcomes. METHOD Two law enforcement agencies served as study sites. A dynamic wait-listed design included a phase when advocates at both sites delivered usual services (US) to victims, a phase when one site was randomly selected to deliver PFA while the other delivered US, and a phase when both sites delivered PFA. Across all phases, 172 crime victims (mean age = 36.4 years; 81% female) were recruited, and a battery assessed their psychiatric symptoms and adaptive functioning at baseline and 1, 2, and 4 months postbaseline. RESULTS From the US to PFA phases, advocates' PFA adherence (i.e., their delivery of PFA components) increased significantly. PFA did not outperform US with regard to improvement on victims' individual psychiatric and adaptive functioning outcomes. However, on a composite global functioning outcome created for this trial, PFA yielded significantly greater improvement relative to US. CONCLUSION Paraprofessional victim advocates have the capacity to deliver PFA. Conclusions regarding the effectiveness of PFA for crime victims vary depending on the nature of the scored outcome variable (individual vs. global), highlighting the importance of careful outcome measurement considerations in future research on PFA.

基于社区的犯罪受害者心理急救随机对照试验。

目标 进行了第一项心理急救 (PFA) 随机对照试验，将犯罪受害者作为参与者。对于研究目标 1，调查人员测试了是否可以培训辅助职业受害者倡导者向犯罪受害者提供心理急救。对于研究目标 2，研究人员测试了 PFA 给药对受害者精神（即 PTSD 症状、躯体化、抑郁、焦虑和物质使用）和适应性功能结果的影响。方法 两个执法机构作为研究地点。动态的候补名单设计包括两个站点的倡导者向受害者提供常规服务（美国）的阶段，随机选择一个站点提供 PFA 而另一个站点提供 US 的阶段，以及两个站点都提供 PFA 的阶段。在所有阶段，172 名犯罪受害者（平均年龄 = 36.4 岁；81% 女性）被招募，并在基线和基线后 1、2 和 4 个月评估了他们的精神症状和适应性功能。结果 从美国到 PFA 阶段，倡导者的 PFA 依从性（即他们提供 PFA 组件）显着增加。在改善受害者的个体精神和适应功能结果方面，PFA 的表现并不优于美国。然而，在为该试验创建的综合全球功能结果中，相对于美国，PFA 产生了显着更大的改善。结论 辅助职业受害者权益倡导者有能力提供心理急救。关于心理急救对犯罪受害者的有效性的结论因评分结果变量的性质（个人与全球）而异，强调在未来 PFA 研究中仔细衡量结果的重要性。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
