Nurses are at high risk for workplace violence, which can lead to psychological problems. The purpose of this study was to determine the relationship between workplace violence, self-efficacy, and PTSD, and to further explore whether self-efficacy mediates the relationship between workplace violence and PTSD among Chinese nurses.
This cross-sectional study was conducted in Liaoning Province, China in 2020. A total of 1,017 valid questionnaires were returned. Each questionnaire included the Workplace Violence Scale, the General Self-Efficacy Scale, the Post-traumatic Stress Disorder Scale (PTSS-10), and demographics information. A hierarchical multiple regression approach was used to explore the mediating role of self-efficacy in the relationship between workplace violence and PTSD. The mediation model was then tested by the PROCESS macro in SPSS.
A total of 1,017 nurses were included in this study, and the average score of PTSD among Chinese nurses was 26.85 ± 13.13 (mean ± SD). After further adjustment for control variables, workplace violence was positively associated with PTSD, explaining 13% of the variance. High self-efficacy was associated with low PTSD, explaining 18% of the variance. Self-efficacy partially mediated the role of workplace violence and PTSD.
The high scores of PTSD among Chinese nurses demand widespread attention. Workplace violence is an important predictor of PTSD in nurses. Self-efficacy is a significant factor in improving PTSD in nurses and mediates the relationship between workplace violence and PTSD. Measures and strategies to improve self-efficacy may mitigate the effects of workplace violence on PTSD in nurses.
护士面临工作场所暴力的高风险，这可能导致心理问题。本研究的目的是确定工作场所暴力、自我效能感和创伤后应激障碍（PTSD）之间的关系，并进一步探讨自我效能感是否在中国护士中中介工作场所暴力与PTSD之间的关系。
本横断面研究于2020年在中国辽宁省进行。共回收1017份有效问卷。每份问卷包括工作场所暴力量表、一般自我效能感量表、创伤后应激障碍量表（PTSS - 10）和人口统计学信息。采用分层多元回归方法探讨自我效能感在工作场所暴力与PTSD关系中的中介作用。然后通过SPSS中的PROCESS宏对中介模型进行检验。
本研究共纳入1017名护士，中国护士PTSD的平均得分为26.85±13.13（均值±标准差）。在进一步调整控制变量后，工作场所暴力与PTSD呈正相关，解释了13%的变异。高自我效能感与低PTSD相关，解释了18%的变异。自我效能感部分中介了工作场所暴力与PTSD的作用。
中国护士中PTSD的高分值得广泛关注。工作场所暴力是护士PTSD的重要预测因素。自我效能感是改善护士PTSD的重要因素，并中介了工作场所暴力与PTSD之间的关系。提高自我效能感的措施和策略可能减轻工作场所暴力对护士PTSD的影响。
