Identification of posttraumatic stress disorder (PTSD) symptoms and diagnoses in survivors of cancer is a growing area of research, but no published data exist regarding the symptom structure of PTSD in survivors of malignant disease. Findings from investigations of the PTSD symptom structure in other trauma populations have been inconsistent and have not been concordant with the re-experiencing, avoidance/numbing, and arousal symptom clusters specified in DSM-IV. The present study employed confirmatory factor analysis to evaluate the extent to which the implied second-order factor structure of PTSD was replicated in a sample of 142 breast cancer survivors. PTSD symptoms were measured using the PTSD Checklist--Civilian Version (PCL-C). Fit indices reflected a moderate fit of the symptom structure implied by the DSM-IV. These findings provide some tentative support for the DSM-IV clustering of PTSD symptoms and for the validity of cancer-related PTSD.
识别癌症幸存者中的创伤后应激障碍（PTSD）症状及诊断是一个不断发展的研究领域，但关于恶性疾病幸存者中PTSD症状结构尚无已发表的数据。对其他创伤人群中PTSD症状结构的调查结果并不一致，且与《精神疾病诊断与统计手册》第四版（DSM-IV）中规定的再体验、回避/麻木和唤醒症状群不一致。本研究采用验证性因素分析来评估PTSD隐含的二阶因素结构在142名乳腺癌幸存者样本中的复制程度。使用创伤后应激障碍检查表——平民版（PCL-C）来测量PTSD症状。拟合指数反映了DSM-IV所隐含的症状结构的适度拟合。这些发现为DSM-IV中PTSD症状的聚类以及与癌症相关的PTSD的有效性提供了一些初步支持。
