The present study aimed to investigate the psychometric properties of the Italian version of the PTSD Checklist for the DSM-V (PCL-5) in a group of adults who had experienced heterogenous traumatic events.
Six hundred and one participants met the inclusion criteria and completed a set of questionnaires through an online survey. Before administering the survey, the PCL-5 was translated into Italian according to the back-translation method. The factorial structure of the PCL-5 was assessed through multiple confirmatory factor analyses. Gender measurement invariance and concurrent and criterion validity were also evaluated.
The instrument had a seven-factor structure and it worked in a similar manner for males and females. With regard to the concurrent validity, results showed that higher PCL-5 scores were associated with higher levels of depression and rumination and lower levels of life satisfaction. Regarding criterion validity, results revealed that PCL-5 scores were, on average, higher for females than for males, and the temporal distance from the traumatic event was negatively correlated with the total PCL-5 score.
The findings indicated that the Italian version of the PCL-5 was able to provide valid and reliable scores for the assessment of PTSD symptoms in the Italian population.
本研究旨在调查经历过异质创伤事件的成年人中，DSM-V 创伤后应激障碍检查表（PCL-5）意大利语版本的心理测量特性。
601 名符合纳入标准的参与者通过在线调查完成了一组问卷。在进行调查之前，根据反向翻译法将 PCL-5 翻译成意大利语。通过多项验证性因素分析评估了 PCL-5 的因子结构。还评估了性别测量不变性和同时效和效标效度。
该工具具有七因子结构，对男性和女性的作用方式相似。关于同时效效度，结果表明，较高的 PCL-5 分数与较高的抑郁和反刍水平以及较低的生活满意度相关。关于效标效度，结果表明，女性的 PCL-5 分数平均高于男性，创伤事件的时间距离与总 PCL-5 分数呈负相关。
研究结果表明，PCL-5 的意大利语版本能够为评估意大利人群的 PTSD 症状提供有效可靠的分数。
