本研究的目的是评估法语版 DSM-5 创伤后应激障碍检查表 (PCL-5) 的心理测量特性,这是一种创伤后应激障碍 (PTSD) 症状的自我报告测量方法,并进一步验证现有英语版本的测量方法。本科生(n = 838 名英国学生,n = 262 名法国学生)在线完成了 PCL-5 以及 PTSD 和抑郁症的其他自我报告症状测量。英语和法语版本的 PCL-5 总分均表现出出色的内部一致性(英语:α = .95;法语:α = .94),以及很强的收敛效度和发散效度。每个版本的四个子量表中的每一个都观察到很强的内部一致性(α> .79)。法国版本测量的重测信度也非常好(r = .89)。验证性因素分析表明,四因素 DSM-5 模型对数据的拟合效果不佳。七因素混合模型最适合每个样本中的数据,但仅略微优于六因素快感缺乏模型。 PCL-5 的法语版本表现出与同一测量的英语版本和 PCL 之前版本相同的心理测量品质。因此,为法语客户服务的临床医生现在可以使用这种广泛使用的筛查工具。关于 PCL-5 和 DSM-5 的新 PTSD 诊断结构的结构有效性,需要进行更多研究。非常需要在临床样本中复制我们的结果。
The purpose of this study is to assess the psychometric properties of a French version of the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), a self-report measure of posttraumatic stress disorder (PTSD) symptoms, and to further validate the existing English version of the measure. Undergraduate students (n = 838 English, n = 262 French) completed the PCL-5 as well as other self-report symptom measures of PTSD and depression online. Both the English and French versions PCL-5 total scores demonstrated excellent internal consistency (English: α = .95; French: α = .94), and strong convergent and divergent validity. Strong internal consistency was also observed for each of the four subscales for each version (α’s > .79). Test-retest reliability for the French version of the measure was also very good (r = .89). Confirmatory factor analysis indicated that the four-factor DSM-5 model was not a good fit of the data. The seven-factor hybrid model best fit the data in each sample, but was only marginally superior to the six-factor anhedonia model. The French version of the PCL-5 demonstrated the same psychometric qualities as both the English version of the same measure and previous versions of the PCL. Thus clinicians serving French-speaking clients now have access to this highly used screening instrument. With regards to the structural validity of the PCL-5 and of the new PTSD diagnostic structure of the DSM-5, additional research is warranted. Replication of our results in clinical samples is much needed.
