亲人的死亡会引发一系列情绪、行为、动机和认知反应，统称为“悲痛”。最近，人们对悲伤反应的经验兴趣重新抬头，现在普遍的共识是，7%-10%的丧失亲人的人经历了强烈的慢性反应，称为长期悲伤(PG)。然而，关于如何最好地概念化这一结构的争论仍在继续。最近的研究通过应用网络或因果系统方法推进了这场辩论。传统的精神病理学观点认为，障碍的症状反映了潜在实体的独立行为，而网络方法则认为，症状本身相互作用才会导致障碍。网络概念化为研究PG的机制提供了新的方法。然而，到目前为止，研究只集中在配偶丧失上，并且只使用了单一的档案数据集。因此，在本文中，我们应用网络分析来检验因失去配偶(研究1，N=193)和失去父母(研究2，N=180)而丧失亲人的个体样本中PG症状之间的关系。参与者完成了PG-13和抑郁症的测量。对比测试表明，每个样本产生的网络并不可靠地不同。这两个网络中最强的联系是渴望和情感痛苦之间的联系。在这两个网络中，无意义是相对核心的，而回避是次要的。研究结果参考理论模型和网络方法对理解PG症状之间的关系可能具有的潜在益处进行了讨论。
The death of a loved one can trigger a range of emotional, behavioural, motivational and cognitive reactions collectively labelled as “grief”. There has been a recent resurgence of empirical interest in grief reactions, and there is now a general consensus that 7%–10% of bereaved individuals experience intense and chronic reactions termed Prolonged Grief (PG). However, there is ongoing debate about how best to conceptualise the construct. Recent studies have advanced this debate by applying a network, or causal systems approach. Whereas traditional views of psychopathology posit symptoms of disorders reflect the independent actions of latent entities, the network approach argues that the symptoms themselves interact to give rise to the disorder. A network conceptualisation offers novel approaches to studying the mechanisms that contribute to PG. To date, however, research has focussed only on spousal loss and only used a single archival data set. Therefore, in this paper we apply network analysis to examine relationships among PG symptoms in samples of individuals bereaved by loss of a spouse (Study 1, N=193) and a parent (Study 2, N=180). Participants completed the PG-13 and a measure of depression. A comparison test suggested the networks produced from each sample were not reliably different. The strongest link in both networks was between yearning and emotional pain. Meaninglessness was relatively central, whereas avoidance was peripheral in both networks. Findings are discussed with reference to theoretical models and the potential benefits a network approach may hold for understanding relationships between symptoms of PG.
