目的考察警察职业风险及其与创伤后应激症状之间的关系。方法2016年9—12月,在全国12个省份选取警察3160名,使用事件影响量表修订版(IES-R)和警察职业风险调查问卷对被试进行创伤后应激症状评估以及职业风险调查。结果发生率较高的警察职业风险有:言语辱骂(63.8%,1887/2958)、遇到过恶意投诉(39.6%,1171/2958)、曾受到要殴打和伤害自己的威胁恐吓(31.8%,941/2958)、受到非器具攻击(26.0%,769/2958)。17.2%(509/2958)的被试警察处于创伤后应激障碍高风险状态。警察职业风险的4个因子分别与事件影响量表得分有正相关(r=0.38、0.39、0.37、0.41,均P<0.01)。回归分析发现,在控制性别、警龄的情况下,发现警察职业风险的4个因子得分均可预测事件影响量表得分(β=0.08、0.23、0.09、0.25,均P<0.001)。结论本研究提示我国警察的创伤后应激症状检出率较高,警察职业风险可预测创伤后应激症状。

Objective To explore the prevalence of work-related violence exposure and its association with posttraumatic stress symptoms among police officers.Methods Totally 3 160 police officers were recruited with convenience sampling in 12 provinces and surveyed with The Impact of Event Scale-R (IES-R) and the Questionnaire of Work-Related Violence for Police Officers between September and December 2016.Results Among the 2 958 respondents with eligible information, the proportions of reporting work-related violence exposure were 63.8%(n = 1 887) to verbal insult, 39.6%(1 171) to malicious complaint, 31.8%(941) to verbal or physical violence threat, and 26.0%(769) to unarmed physical attack, respectively. Of the respondents, 17.2%(509) were identified at a high risk of post-traumatic stress disorder. The total IES-R score of the respondents was positively correlated significantly with their work-related violence exposure to verbal insult (r = 0.38), threat (r = 0.39), attack or injury (r = 0.37), and being afraid of injury in future (r = 0.41)(P < 0.01 for all) and the four work-related violence exposures were significant predictors of total IES-R score after adjusting for gender and years of working as a police officer, with the β values of 0.08, 0.23, 0.09, and 0.25 (all P < 0.001).Conclusion The results of the study suggest that the detection rate of posttraumatic stress symptoms is high and work-related violence exposure could predict the incidence of posttraumatic stress symptoms among police officers in China.
