The extent and severity of the psychological effects following chemical release disasters have not been widely reported. The aim of this study was to examine the prevalence of hydrogen fluoride (HF)-related posttraumatic stress disorder (PTSD) and to identify associated psychological risk factors. On September 2012, an estimated 8 to 12 tons of HF gas, which dissolves in air moisture to form droplets of corrosive hydrofluoric acid, escaped from an industrial complex in Gumi, South Korea. Ten months later, structured questionnaires that included items from the Impacts of Event Scale (revised Korean version) as well as questions about demographic and psychological risk factors related to PTSD were distributed to workers in the affected area. The prevalence rate of PTSD was 5.7%. The odds of PTSD in non-alcohol-dependent workers (odds ratio [OR] = 3.10, 95% confidence interval [CI] = [1.27, 7.60]) was significantly higher than in alcohol-independent workers. The OR for PTSD in workers with anxiety (OR = 7.63, 95% CI = [2.10, 27.71) was significantly higher than the OR workers without anxiety. The odds of PTSD in workers with high perceived stress scale (PSS) scores (OR = 8.72, 95 % CI = [2.29, 33.16]) was significantly higher than for workers with low PSS. Alcohol dependence, psychiatric symptoms at the time of the event, anxiety, and high PSS were associated with HF-related PTSD. Long-term employee assistance programs are needed to assist occupational health nurses and clinicians to reduce PTSD after industrial disasters.
化学物质泄漏灾难后心理影响的程度和严重性尚未得到广泛报道。本研究的目的是调查与氟化氢（HF）相关的创伤后应激障碍（PTSD）的患病率，并确定相关的心理风险因素。2012年9月，据估计有8至12吨HF气体从韩国龟尾的一个工业园区泄漏，该气体溶于空气中的水分形成腐蚀性氢氟酸液滴。十个月后，向受影响地区的工人发放了结构化问卷，其中包括事件影响量表（修订韩文版）中的项目以及与PTSD相关的人口统计学和心理风险因素问题。PTSD的患病率为5.7%。非酒精依赖工人患PTSD的几率（优势比[OR]=3.10，95%置信区间[CI]=[1.27,7.60]）显著高于非酒精依赖工人。焦虑工人患PTSD的OR值（OR=7.63，95%CI=[2.10,27.71]）显著高于无焦虑工人。感知压力量表（PSS）得分高的工人患PTSD的几率（OR=8.72，95%CI=[2.29,33.16]）显著高于PSS得分低的工人。酒精依赖、事件发生时的精神症状、焦虑和高PSS与HF相关的PTSD有关。需要长期的员工援助计划来帮助职业健康护士和临床医生减少工业灾难后的PTSD。
