本研究采用验证性因素分析（CFA）方法，探讨创伤后应激障碍（PTSD）和酒精使用障碍（AUD）的相关因素，以进一步了解这两种障碍之间的共病关系。有海外部署史的俄亥俄州国民警卫队士兵参加了调查（n = 1215）。受试者完成PTSD量表和用于诊断AUD的全国药物使用调查中的12个项目的调查。CFA的结果表明，PTSD的四个因素和一个单一AUD因素的组合模型非常适合数据。PTSD的因素和潜在的AUD因素之间的相关系数为0.258-0.285，PTSD的焦虑因素表现出最强的相关性。然而，Wald检验的参数约束表明，AUD与PTSD的烦躁不安的相关性并不比其他PTSD因素更高。PTSD的烦躁不安模型的所有四个因素都表现出与AUD的相关性。烦躁不安的PTSD的结构的作用进行了讨论。
The objective of this study was to evaluate the relationship between factors of posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) using confirmatory factor analysis (CFA) in order to further our understanding of the substantial comorbidity between these two disorders.CFA was used to examine which factors of PTSD's dysphoria model were most related to AUD in a military sample. Ohio National Guard soldiers with a history of overseas deployment participated in the survey (n = 1215). Participants completed the PTSD Checklist and a 12-item survey from the National Survey on Drug Use used to diagnosis AUD.The results of the CFA indicated that a combined model of PTSD's four factors and a single AUD factor fit the data very well. Correlations between PTSD's factors and a latent AUD factor ranged from correlation coefficients of 0.258-0.285, with PTSD's dysphoria factor demonstrating the strongest correlation. However, Wald tests of parameter constraints revealed that AUD was not more correlated with PTSD's dysphoria than other PTSD factors.All four factors of PTSD's dysphoria model demonstrate comparable correlations with AUD. The role of dysphoria to the construct of PTSD is discussed.
