| 目的 初步编制维和官兵创伤及压力暴露量表，并评价其信度及效度。方法 基于文献回顾和访谈法确定量表的理论模型和结构模型，建立条目池，编制测试条目，经专家修订形成基本条目。于2019年10月对某2批赴南苏丹维和步兵营733名官兵进行测试，通过项目分析等进行条目筛选，应用探索性因素分析等形成基本量表。运用量表于2020年1月对另一批赴南苏丹维和步兵营595名官兵进行验证性测试，以Cronbach's α系数和分半信度检验量表的信度，通过相关分析、验证性因素分析等验证量表的结构效度，以军事应激症状核查表（PCL-M）为校标表进行校标关联效度检验，通过ROC曲线评估量表的预测效度。结果 量表最终形成5个因子，分别为维和期创伤性事件、个人生活应激源、人际关系应激源、任务评价和过去创伤性事件，共25个条目，累积贡献率达62.909%。验证性因子分析结果显示总量表同质信度Cronbach's α系数为0.909，分半信度为0.806。结构效度检验中各拟合指数均处于理想标准值范围内，χ2/df=2.438，均方根残差=0.042，近似误差均方根=0.082。各维度得分均与总分呈正相关（r=0.411～0.727，P均<0.01）。量表总分与PCL-M校标表总分的校标关联效度为0.623（P<0.01）。以5%为划分点计算量表的预测效度，AUC值为0.937（95% CI 0.907～0.967）。结论 经过严格的条目筛选后初步编制了维和官兵创伤及压力暴露量表，量表的条目符合代表性好、灵敏度高、区分性好的原则，达到了编制的要求。 |

| Abstract: |
| Objective To develop a trauma and stress exposure scale for peacekeepers and to evaluate its reliability and validity. Methods The theoretical and structural models of the scale were determined based on literature review and interview, and an item pool was established, which was revised by experts to form basic items. In Oct. 2019, 733 soldiers and officers from 2 peacekeeping infantry battalions to South Sudan were tested, items were screened through project analysis, and basic scale was formed by exploratory factor analysis. A confirmatory test was conducted on 595 officers and soldiers of another peacekeeping infantry battalion to South Sudan in Jan. 2020. The reliability of the scale was verified by the Cronbach’s α coefficient and the split-half reliability test scale, and the validity was verified by correlation analysis and confirmatory factor analysis. The post-traumatic stress disorder (PTSD) check list-military version (PCL-M) scale was used as the calibration table to test the calibration correlation validity, and the predictive validity of the scale was evaluated by ROC curve. Results The scale finally included 25 items in 5 factors (traumatic events during peacekeeping, personal life stressors, interpersonal stressors, task evaluation and past traumatic events), with an overall cumulative contribution rate of 62.909%. Confirmatory factor analysis showed that the Cronbach’s α coefficient was 0.909 for homogeneity reliability and 0.806 for the split-half reliability of the whole scale. In the structural validity test, all the fitting indexes were in the ideal standard range (χ2/df=2.438, root mean square residual=0.042, and root mean square error approximation=0.082). The score of each dimension was positively correlated with the total score (r=0.411-0.727, all P<0.01). The calibration correlation validity between the total scores of the scale and the PCL-M scale was 0.623 (P<0.01). The predictive validity of the scale was calculated at 5%, and the area under curve was 0.937 (95% confidence interval 0.907-0.967). Conclusion The trauma and stress exposure scale for peacekeepers has been preliminarily developed after strict item selection. The items of the scale are in line with the principles of good representativeness, high sensitivity and good differentiation, and meet the requirements of the development. |
