BACKGROUND
Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) are frequently comorbid. One explanation for this comorbidity is that PTSD has a constellation of "dysphoria" symptoms resembling depression.
METHOD
Using confirmatory factor analysis we tested the role of DSM-5 PTSD׳s dysphoria factor in relation to MDD symptom dimensions of somatic and non-somatic psychopathology. 672 Ohio National Guard soldiers completed DSM-5 measures of PTSD and MDD symptoms in an epidemiological study.
RESULTS
Results indicated that in contrast to other PTSD factors, PTSD׳s dysphoria factor was more related to MDD׳s somatic and non-somatic factors.
LIMITATIONS
Limitations include generalizability to the epidemiological population of trauma-exposed military veterans rather than civilians, and reliance on self-report measures.
CONCLUSIONS
Implications concerning clinical psychopathology and comorbidity of PTSD are discussed, including whether PTSD should be refined by removing its non-specific symptoms.
背景
创伤后应激障碍（PTSD）和重度抑郁障碍（MDD）经常共病。这种共病的一个解释是 PTSD 有一系列类似于抑郁的“心境恶劣”症状。
方法
我们使用验证性因子分析来测试 DSM-5 PTSD 的心境恶劣因子与 MDD 症状的躯体和非躯体精神病理学维度之间的关系。672 名俄亥俄州国民警卫队士兵在一项流行病学研究中完成了 DSM-5 PTSD 和 MDD 症状的测量。
结果
结果表明，与其他 PTSD 因素相比，PTSD 的心境恶劣因子与 MDD 的躯体和非躯体因素更为相关。
局限性
局限性包括对创伤后暴露的退伍军人的流行病学人群的普遍性，而不是对平民的普遍性，以及对自我报告测量的依赖。
结论
讨论了与 PTSD 的临床精神病理学和共病相关的问题，包括是否应该通过去除其非特异性症状来改进 PTSD。
