抑郁症和创伤后应激障碍 (PTSD) 是高度共存的疾病，可能在遭受心理创伤后出现。本研究使用双变量潜在差异评分结构方程模型检查了它们的时间顺序和相互影响。来自 182 名急诊室患者的纵向数据显示，抑郁症状严重程度与创伤事件后不久开始的 3 个时间间隔内 PTSD 侵入、回避和过度警觉的变化呈正相关。抑郁症得分越高，预期 PTSD 症状严重程度就会增加（或恶化）。 PTSD 症状严重程度对抑郁症状严重程度变化的影响模式完全遵循健康和幸福的总体趋势。结果根据创伤后抑郁症和 PTSD 症状严重程度的动态相互作用和相关机制进行了讨论。
Depression and posttraumatic stress disorder (PTSD) are highly comorbid conditions that may arise following exposure to psychological trauma. This study examined their temporal sequencing and mutual influence using bivariate latent difference score structural equation modeling. Longitudinal data from 182 emergency room patients revealed level of depression symptom severity to be positively associated with changes in PTSD intrusion, avoidance, and hyperarousal over 3 time intervals, beginning shortly after the traumatic event. Higher score on depression anticipated increases (or worsening) in PTSD symptom severity. The pattern of influence from PTSD symptom severity to change in depression symptom severity simply followed the general trend toward health and well-being. Results are discussed in terms of the dynamic interplay and associated mechanisms of posttrauma depression and PTSD symptom severity.
