This study aimed to investigate the prevalence, clinical characteristics, and the correlates of nonsuicidal self-injury (NSSI) in firefighters. We also investigated the mediating role of NSSI frequency in the association between posttraumatic stress disorder (PTSD), depression, and suicidal behavior.
A total of 51,505 Korean firefighters completed a web-based self-reported survey, including demographic and occupational characteristics, NSSI, PTSD, depression, and suicidal behavior. Multivariable logistic regression analyses and serial mediation analyses were performed.
The 1-year prevalence of NSSI was 4.67% in Korean firefighters. Female gender, the presence of recent traumatic experience, and PTSD and depression symptoms were correlated with NSSI. Serial mediation analyses revealed that NSSI frequency mediated the association between PTSD, depression, and suicidal behavior; it indicates more severe PTSD was sequentially associated with more severe depression symptoms and more frequent NSSI, leading to higher risk of suicidal behavior.
NSSI is prevalent and may play a significant mediating role when PTSD is associated with suicidal behavior in firefighters. Our results imply the need for screening and early intervention of NSSI in firefighters.
本研究旨在调查消防员中非自杀性自伤（NSSI）的患病率、临床特征及其相关因素。我们还研究了NSSI频率在创伤后应激障碍（PTSD）、抑郁和自杀行为之间的关联中所起的中介作用。
共有51,505名韩国消防员完成了一项基于网络的自我报告调查，内容包括人口统计学和职业特征、NSSI、PTSD、抑郁和自杀行为。进行了多变量逻辑回归分析和系列中介分析。
韩国消防员中NSSI的1年患病率为4.67%。女性、近期有创伤经历、PTSD和抑郁症状与NSSI相关。系列中介分析显示，NSSI频率介导了PTSD、抑郁和自杀行为之间的关联；这表明更严重的PTSD依次与更严重的抑郁症状和更频繁的NSSI相关，从而导致更高的自杀行为风险。
NSSI在消防员中很普遍，并且在PTSD与消防员自杀行为相关时可能起重要的中介作用。我们的结果表明有必要对消防员中的NSSI进行筛查和早期干预。
