本研究探讨了重度抑郁症症状的潜在因素与DSM-5创伤后应激障碍（PTSD）症状之间的关系（美国精神病学协会，2013）。266名有创伤史的非临床样本参与了这项研究。进行了解释性因素分析，以评估DSM-5 PTSD模型和烦躁模型的拟合，以及由躯体和非躯体因素组成的抑郁模型。DSM-5 PTSD模型表现出比烦躁模型更好的拟合。Wald测验表明，PTSD在认知和情绪因子上的负性改变与抑郁症的非躯体因素的相关性比躯体因素的相关性更强。这项研究进一步探讨了PTSD和抑郁因素之间的关系，以更好地了解这两种疾病之间的高共患病率的性质。此外，本研究提供了一个初步的分析，新的DSM-5诊断标准的PTSD。
This study examined the relationship between the underlying latent factors of major depression symptoms and DSM-5 posttraumatic stress disorder (PTSD) symptoms (American Psychiatric Association, 2013). A nonclinical sample of 266 participants with a trauma history participated in the study. Confirmatory factor analyses were conducted to evaluate the fit of the DSM-5 PTSD model and dysphoria model, as well as a depression model comprised of somatic and nonsomatic factors. The DSM-5 PTSD model demonstrated somewhat better fit over the dysphoria model. Wald tests indicated that PTSD's negative alterations in cognitions and mood factor was more strongly related to depression's nonsomatic factor than its somatic factor. This study furthers a nascent line of research examining the relationship between PTSD and depression factors in order to better understand the nature of the high comorbidity rates between the two disorders. Moreover, this study provides an initial analysis of the new DSM-5 diagnostic criteria for PTSD.
