目标。目的：对照结构化临床访谈(SCID-1)，验证创伤后应激障碍(PTSD-8)在创伤后应激障碍中的应用，并检验创伤后应激障碍在慢性疼痛患者中的潜在结构。共有51名暴露在创伤事件中的慢性非恶性疼痛患者从一个多学科疼痛中心连续招募。所有参与者都回答了一份基线问卷，然后是创伤后应激障碍-8和创伤后应激障碍诊断性访谈。最后，运用验证性因素分析(CFA)对419例慢性非恶性疼痛患者的PTSD-8的潜在结构进行了检验。总体而言，33.3%的人被诊断为创伤后应激障碍。研究发现，PTSD-8与诊断性访谈相比具有良好的总体准确性。PTSD-8量表与抑郁、焦虑因子分有较强的相关关系，具有较好的收敛效度。PTSD-8三因素结构的CFA结果与创伤后应激障碍的8种症状有很好的契合性。总体而言，结果表明，PTSD-8是评估慢性疼痛患者可能存在的创伤后应激障碍的有效短期筛查工具。此外，PTSD-8量表包括八个条目中即将出现的ICD-11创伤后应激障碍症状。因此，创伤后应激障碍-8很可能也被用来测量被提议的ICD-11创伤后应激障碍。
Objectives. The aim was to validate the short PTSD-8 scale against the Structured Clinical Interview (SCID-1) for post-traumatic stress disorder and to test the latent structure of post-traumatic stress disorder in chronic pain patients.Methods. A total of 51 chronic nonmalignant pain patients exposed to a traumatic event were consecutively recruited from a multidisciplinary pain center. All participants answered a baseline questionnaire followed by the PTSD-8 and the diagnostic interview for PTSD. Finally, the latent structure of PTSD-8 was tested in a large cohort of 419 patients with chronic nonmalignant pain using confirmatory factor analysis (CFA).Results. In total, 33.3% had a diagnosis of PTSD. A good overall accuracy was found validating the PTSD-8 against the diagnostic interview. Convergent validity was indicated as the PTSD-8 correlated strongly with scores of depression and anxiety. The results of the CFA for the PTSD-8 threefactor structure provided excellent fit for the eight post-traumatic stress disorder symptoms.Conclusions. Overall, the results showed that the PTSD-8 is a valid short screening tool to assess possible post-traumatic stress disorder among patients with chronic pain. In addition, the PTSD-8 scale comprises all of the upcoming ICD-11 posttraumatic stress disorder symptoms within its eight items. Thus, the PTSD-8 is likely also to measure the proposed ICD-11 post-traumatic stress disorder.
