Evidence shows that the centrality of a loss-event maintains emotional distress following loss. Aims of the current study were to examine (i) if subgroups of bereaved people can be distinguished based on their endorsement of different manifestations of loss-centrality, (ii) if subgroup membership was associated with socio-demographic and loss-related variables, and (iii) the linkage of subgroup membership with symptom-levels of prolonged grief (PG), posttraumatic stress (PTS), and depression assessed concurrently and 6 months later.
Three-hundred ninety-eight bereaved people completed the 7-item Centrality of Event Scale, with their loss as anchor-event and completed symptom-measures concurrently and 6 months later. Latent profile analysis (LPA) was used to identity profiles of loss-centrality.
LPA revealed a three-profile solution representing low, average, and high centrality classes, respectively. The death of a partner and younger age increased the likelihood of membership of classes evidencing stronger centrality. Membership of the low centrality class was associated with lower concurrent PG, PTS, and depression; membership of the high centrality class predicted elevated PG 6 months later, beyond baseline PG.
Subgroups of loss-centrality were distinguished by increasing endorsement of all (rather than some) manifestations of loss-centrality. Clinical implications are discussed.
有证据表明，丧失事件的中心地位会在丧失后持续引起情绪困扰。本研究的目的是检验：（i）是否可以根据丧亲者对丧失中心性不同表现的认可程度来区分亚组；（ii）亚组成员资格是否与社会人口学和与丧失相关的变量有关；（iii）亚组成员资格与同时评估和 6 个月后评估的延长哀伤（PG）、创伤后应激（PTS）和抑郁的症状水平之间的联系。
398 名丧亲者完成了 7 项事件中心性量表，以他们的丧失为锚定事件，并同时和 6 个月后完成症状测量。潜在剖面分析（LPA）用于确定丧失中心性的特征。
LPA 揭示了一个三特征解决方案，分别代表低、中、高中心性类别。伴侣的死亡和年龄较小增加了具有更强中心性特征的类别成员的可能性。低中心性类别的成员资格与同时发生的 PG、PTS 和抑郁程度较低相关；高中心性类别的成员资格预测 6 个月后 PG 升高，超出基线 PG。
通过越来越多地认可丧失中心性的所有（而不是一些）表现，区分了丧失中心性的亚组。讨论了临床意义。
