Most suicides in the United States are enacted with firearms, and firearm ownership/access and unsafe storage are associated with elevated suicide risk. Exaggerated perceptions of threat, which are characteristic of post‐traumatic stress disorder (PTSD), might lead to the acquisition and/or unsafe storage of firearms, thereby increasing suicide risk. In this systematic review, we evaluated 17 peer‐reviewed manuscripts (18 studies) that examined the relation between PTSD and firearm ownership/access, firearm storage practices, and related features thereof. We found it challenging to interpret results of the existing literature due to heterogeneity of methods employed and methodological limitations (e.g., asynchronous assessment of constructs). We identify multiple avenues for future research to better understand the extent to which PTSD is related to firearm‐related variables.

创伤后应激障碍和枪支拥有权，使用权和保管做法：系统回顾

在美国，大多数自杀是与枪支相关的，枪支的拥有/使用和不安全的存放都与自杀风险增加有关。创伤后应激障碍（PTSD）的特征是对威胁的夸大理解可能会导致枪支的获取和/或不安全存放，从而增加自杀风险。在本系统评价中，我们评估了17篇经过同行评审的手稿（18项研究），这些手稿检查了PTSD与枪支所有权/使用权，枪支存储做法及其相关特征之间的关系。我们发现，由于所采用方法的异质性和方法学上的局限性（例如，结构的异步评估），难以解释现有文献的结果。
