War survivors often report symptoms of post-traumatic stress disorder (PTSD), depression, anxiety, and somatization. Hence, understanding symptom constellations among different populations of war survivors is critical.
Using the network approach to psychopathology, we examined symptom centrality for these conditions in war survivors from Balkan countries who had stayed in the area of former conflict compared to those individuals from Balkan countries who had fled to Western European countries (N = 4,167) with the Impact of Events Scale-Revised and the Brief Symptom Inventory. We further compared networks for war survivors who met criteria for PTSD-diagnosis (assessed with the MINI-International Neuropsychiatric Interview) to those without PTSD-diagnosis.
Globally, networks were similar across the groups, whereas specific differences emerged in symptom centrality. More consistencies were found between PTSD and Western country networks, which may be partially explained by a higher prevalence of PTSD in those who had fled to Western European than in those who had stayed in the Balkan countries.
Given the cross-sectional nature of our data, the directionality of edges in our networks remains unclear. Further, higher levels of trauma exposure and symptom severity in Western country participants may have confounded results.
The PTSD findings are in line with previous research on PTSD symptoms. They further provide novel insights into depressive, anxiety, and somatization symptoms in survivors of war. These findings need to be substantiated and call for future intervention studies that test the effects of targeting central symptoms we identified in our study.
战争幸存者常报告创伤后应激障碍(PTSD)、抑郁、焦虑和躯体化等症状。因此,了解不同战争幸存者群体的症状组合至关重要。
我们使用精神病理学网络方法,比较了来自巴尔干国家的留在前冲突地区的战争幸存者(N=4167)与逃离到西欧国家的战争幸存者(N=4167)的症状中心性,使用修订后的事件影响量表和简明症状量表进行评估。我们还比较了符合 PTSD 诊断标准(使用 MINI-国际神经精神病学访谈进行评估)的和不符合 PTSD 诊断标准的战争幸存者的网络。
总体而言,各组的网络相似,而症状中心性存在特定差异。PTSD 和西方国家网络之间存在更多的一致性,这可能部分解释了逃离到西欧的人比留在巴尔干国家的人 PTSD 患病率更高。
由于我们的数据是横断面的,网络中边缘的方向性仍不清楚。此外,西方国家参与者的创伤暴露和症状严重程度较高可能会混淆结果。
PTSD 的发现与之前关于 PTSD 症状的研究一致。它们进一步提供了关于战争幸存者的抑郁、焦虑和躯体化症状的新见解。这些发现需要得到证实,并呼吁未来进行干预研究,以测试我们在研究中确定的针对核心症状的效果。
