Abstract：
This survey study aimed to contribute to the extensive debate on the dimensionality of the Posttraumatic Stress Disorder Checklist for the DSM-5 (PCL-5) questionnaire by examining the psychometric properties and construct validity of its Hungarian version and relying on the inspection of a conceptual network of related variables, that is, perceived stress, hostility, and resilience. Confirmatory factor analysis (CFA), exploratory structural equation modelling (ESEM) and path analysis were applied on data collected from 177 paramedics and 66 professionals from the social field (58.4% male; Mage = 43.5 ± 9.96 years). Despite the acceptable fit indices gained with CFA when testing the original four-factor DSM-5 model of PCL-5, strong associations (r = 0.69-0.90) between subscales were found. Thus, ESEM was applied and as a result a new, three-factor version of the DSM-5 model of PCL-5 was proposed due to significant crossloadings that was theoretically also supported. The Reexperiencing and Avoidance subscales were merged and named Difficulty with Assimilation of Experience (DAE). In the path analysis only two of the tested associations were not significant using the new factor structure, in which stress fully mediated the relationship between resilience and DAE, and resilience and Hyperarousal. Overall, the hypothesised pathways between variables fit the collected data well. (weighted least squares mean-and variance-adjusted χ2 = 503.750 (df = 270), comparative fit index = 0.948, Tucker-Lewis index = 0.939, root mean square error of approximation (90% confidence interval) = 0.064 (0.055-0.073), weighted root mean square residual = 1.024). Our analysis of the Hungarian version of PCL-5 contributes to the testing of a DSM-5-based questionnaire measuring posttraumatic stress disorder symptomology.
摘要：
这项调查研究旨在通过检查匈牙利版本的心理测量学特性并构建其有效性，并依靠检查来促进对DSM-5（PCL-5）问卷的创伤后应激障碍清单维度的广泛辩论相关变量的概念网络，也就是说,感知压力，敌意,和韧性。验证性因素分析(CFA)探索性结构方程模型(ESEM)和路径分析应用于从177名护理人员和66名来自社会领域的专业人员(58.4%为男性;Mage=43.5±9.96岁)收集的数据。尽管在测试PCL-5的原始四因素DSM-5模型时，CFA获得了可接受的拟合指数，但发现了子量表之间的强关联（r=0.69-0.90）。因此，ESEM被应用，结果是一种新的，由于理论上也支持的显着交叉载荷，提出了PCL-5的DSM-5模型的三因素版本。将重新体验和避免子量表合并，并命名为经验同化困难（DAE）。在路径分析中，使用新的因子结构，只有两个测试的关联不显著，其中压力完全介导了韧性和DAE之间的关系，和韧性和过度唤醒。总的来说,变量之间的假设路径与收集的数据吻合良好.(加权最小二乘均值和方差调整后的χ2=503.750(df=270)，比较拟合指数=0.948,塔克-刘易斯指数=0.939,近似均方根误差(90%置信区间)=0.064(0.055-0.073),加权均方根残差=1.024)。我们对匈牙利版本的PCL-5的分析有助于测试基于DSM-5的问卷，该问卷测量了创伤后应激障碍的症状学。
